To evaluate the present status of treatment of chronic pancreatitis, 116 consecutive patients with chronic pancreatitis during the last decade (1986～1996) have been surveyed retrospectively. The clinical date has been analized statisticaly. Etiology: biliogenic 56 cases (48.3%), alcoholic 17 (14.6%), idiopathic 34 (29.3%) and other 9 cases (7.8%). Better result was achieved in surgical treatment group (81 cases) than in conservative group (35 cases), pain free: 65.5% vs 33.3%. The accumulated five-year survival rate was 56.3%, 92.2% and 78.1% in alcoholic, billiogenic and idiopathic type of chronic pancreatitis respectively. Morbidity and mortality of diarrhea and diabetes mellitus increased at followup. The authors conclude that the chronic pancreatitis patients associated with obstruction of biliopancreatic duct should undergo operation early and will ameliorate abdominal pain.
ObjectiveTo review the current situation of total knee arthroplasty (TKA) used in young patients with osteoarthritis. MethodsThe recent literature in the treatment of osteoarthritis with TKA in young patients was extensively reviewed. The characteristics, curative effect, and postoperative satisfaction degree of TKA in young patients were analyzed and summarized. ResultsYoung patients have longer life expectancy and higher activity, which may lead to much higher expectation of the TKA. Comparing with elderly patients, young patients obtain equal or better effectiveness after TKA, but they are likely to not be satisfied with the effects because of low survival rate of the prosthesis. At present, continuous development of implant design, prosthesis material, and operation technique are in progress to reduce wear, hence to prolong the implant survivorship so as to meet the desire of young patients. However, the studies of the big samples and long-term follow-up are required to confirm the clinical advantages of such developments. ConclusionWith the trend of TKA in young patients, surgeons should have a good understanding of the patients' demands, select suitable prosthesis and give appropriate preoperative counseling to build up an objective expectation of curative effect, which will lead to a better doctor-patient relationship.
Objective To probe the relationship of differentiation degree with spread or survival prognosis in retinoblastoma (RB). Methods Clinical data, follow up status and eyeball specimens in 156 RB cases were investigated retrospectively. The tumors were divided into differentiated and undifferentiated groups. Conditions of the tumor invasion of ocular or surrounding tissues were reviewed. The fatality rate was obtained from the follow-up materials of 82 cases of RB. The fatality rate and the invasion rate between the two types were compared statistically by Chi-square test. In addition, the relation between the tumor invasion and death ,and the average survival time for dead people after surgery were explored. Results Local invasion of tumor cell was found in 8 eyes among 17 eyes with differentiated RB (47.06%),and in 66 eyes among 139 eyes with undifferentiated RB (47.48%).There was no significant difference with regards to the local invasion between the two types ( The fatality rate of cases of differentiated RB was 27.27%,and 22.54% in undifferent iated RB, and there was no statistical difference between the two types .The fat ality rate for patients with orbital and scleral extension was 100%, optic nerve invasion (grade Ⅳ) was 62.50%,and uveal invasion was 22.22%.The survival time for the dead victims were from 5 months to 41 months and averaged to 21.92 months. Conclusion There was no significant differ ence both in survival prognosis and local invasion between the two types. The survival prognosis of metastatic RB was dependent on the degree of spread and the efforts of treatment and regardless of the types of differentiation of RB cells.

Objective To evaluate the influence of histopathological invasion on the survival prognosis of patients with unilateral retinoblastoma. Methods Seventyseven patients with unilateral retinoblastoma who were treated by primary enucleation were followed up after treatment. The patients were followed up for a median period of 49 months (range from 1 week to 89 months). The survival data were collected by follow-up appointment, telephone or letter. The Kaplan-Meier method was used to calculate the cumulative survival rate and curve comparison was done with the log-rank test including the degree of the optic nerve invasion, choroidal invasion, choroidal invasion with or without optic nerve invasion, as well as the anterior segment involvement or not. Results The two years survival rate was 88.31%. The survival rate of the group with tumor involvement in the cut end of optic nerve was 16.67%, and significantly lower than other groups with optic nerve involvement (chi;2=19.51, 18.42, 18.42, 14.39; P=0.000 0).The survival rate of the group with massive choroidal invasion and scleral involvement was 60.00% and significantly lower than the group without choroidal involvement (chi;2=7.69，P=0.005 5). The survival rate of the group with optic nerve involvement and massive choroidal invasion was 75.00%, and the survival rate of the group with optic nerve involvement and scleral or orbital invasion was 60.00%. The survival rate of those two groups were significantly lower respectively than the group only with optic nerve invasion（chi;2=4.25, P=0.039 3;chi;2=7.59, P=0.005 9）.There was no significant difference of survival rate between groups with or without anterior segments involvement (chi;2=0.05，P=0.823 5).Conclusions The risk factors for RB death include the surgical marginal involvement of optic nerve, massive choroidal invasion combined with optic nerve and scleral involvement. The anterior segment involvement has no effect on prognosis of patients with unilateral retinoblastoma.
ObjectiveTo overview the various molecular biological index to judge the prognosis of intrahepatic cholangiocarcinoma (ICC), in order to promote ICC patients follow-up treatment, improve survival rate, and quality of life of the patients. Methods"ICC" and "prognostic factor" were searched as key words by PubMed and CNKI series full-text database retrieval systems from 2000 to 2015. Totally 48 English papers and 15 Chinese papers were obtained. Choice criteria:the molecular biological index that affect the prognosis of ICC patients, and can effectively guide treatment. According to the choice criteria, 45 papers were finally analyzed. ResultsThe indicators of Homer1, mucin 1 (MUC1)\mucin 4 (MUC4), lactate dehydrogenase A (LDH-A), Beclin1, Smad4, protein tyrosine kinase-7 (PTK7), IMP3, cytokeratin 7 (CK7)/cytokeratin 20 (CK20), and sphingosine kinase 1 (SPHK1) could be used as prognostic factors in the survival of patients with ICC, and to determine tumor size and stage, vascular invasion, nerve injury, and lymph node metastasis, are of great clinical significance. ConclusionThese indicators have a significant meanning in the prognosis of ICC and the adjustment of the follow-up treatment.
ObjectiveTo observe the clinical characteristics and survival rate of the patients with extraocular retinoblastoma (RB). MethodsThis is a retrospective case analysis. From November 2003 to May 2015, 38 eyes of 31 patients with RB in the extra-ocular stage from 213 RB patients were enrolled in this study. There were 18 males and 13 females. Bilateral lesions were observed in 7 patients and unilateral lesions were observed in 24 patients.19 patients were diagnosed at less than 2 years old, 10 patients at 2 to 5 years old, and 2 patients at age over 5 years old. First visit time was less than 1 month in 12 patients, from 1 to 3 months in 15 patients, over 3 months to 6 months in 4 patients. Medical history and family history were record at the first visit. All patients underwent orbital CT, MRI, double color Doppler imaging and wide angle digital retinal imaging system. CT and (or) MRI examination detected tumor extraocular invasion. Histopathological examination showed that there were tumor cells invasion of the scleral, optic nerve root and optic nerve. Chemotherapy was done after surgery. In the extra-ocular stage, 3 to 6 rounds of intensive chemotherapy combined with orbital radiotherapy were done. The average follow-up period was (25.5±4.5) months after treatment. The cumulative survival rate was observed after 6 months, 1 and 5 years after treatment, and the relationship between the initial age, time, sex, single eye, tumor and survival time of the patients was analyzed. ResultsThe extraocular RB accounted 14.55% of all RB patients in this study. There is no family history of RB, no special history. There were 15 patients with leukocoria and yellow-white reflection in the pupil; 5 patients with lacrimation, swelling, photophobia and exophthalmos; 11 patients with strabismus. The cumulative survival rate at 6 months, 1, 5 years after treatment was (78.0±9.0)%, (62.0±11.0)%, (57.0±11.0)% respectively. The average survival time was (53.9±7.8) months; the cumulative survival rate was (59.3±11.3)%. When the age of first visit was less than 1 month, 1-3 months, 3-6 months, the median survival time was 78, 15 and 18 months respectively, the cumulative survival rate was 100.0%, (40.0±21.9)% and (25.0±21.7)%, respectively. The survival time of the newly diagnosed patients at 1 month was more than at 1 to 6 months, and the difference was statistically significant (t=9.20, P < 0.05). Conclusions14.55% of all RB patients was extraocular RB in this study. One of the most common clinical manifestations is leukocoria at the first visit. The cumulative survival rate of extraocular RB is lower, while the survival rate of patients with the age of first visit time was less than 1 month is higher.
Objective Through conducting a meta-analysis using the methodology of Cochrane review, to assess the effectiveness and safety of graft-versus-host disease (GVHD) prophylaxis with antithymocyte globulins (ATGs) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Such databases as PubMed (1966 to March 2011), EMbase (1974 to March 2011), the Science Citation Index databases (1900 to March 2011), The Cochrane Library (1996 to March 2011), CBMdisc (1978 to March 2011), and CNKI (1979 to March 2011) were electronical1y searched. The references of all identified studies were retrieved for collecting more randomized controlled trials (RCTs) and non-RCTs. Two reviewers independently screened the trials according to inclusion and exclusion criteria, abstracted the data, and assessed the methodology quality of the included studies. Meta-analyses were performed using RevMan 5.0.2 software. Results Thirteen clinical trials were included, of which 2 were RCTs involving 310 patients and the other 11 were non-RCTs involving 1480 patients. The results of meta-analyses showed that compared with the Non-ATG group, the pooled risk ratio (RR) and 95%CI of the ATG group in acute GVHD II-IV incidence rate, acute GVHD III-IV incidence rate, chronic GVHD (limited plus extensive) incidence rate, chronic GVHD (extensive) incidence rate, overall survival (OS) rate, non-relapse mortality (NRM) rate, and relapse rate were 0.77 (0.67, 0.87), 0.54 (0.44, 0.68), 0.58 (0.51, 0.65), 0.35 (0.26, 0.46), 1.14 (1.04, 1.25), 0.81 (0.69, 0.93), and 1.24 (0.98, 1.57), respectively. Conclusion The addition of ATGs to GVHD prophylaxis can reduce the incidence of acute and chronic GVHD, decrease NRM, and increase OS, but has no obvious interference with relapse rate.
Objective The survival data of patients with colon cancer who were treated by laparoscopic-assisted surgery and open surgery three years after operation were analyzed and contrasted, which provided data to support the future treatment. Methods The 217 patients who were cured by laparoscopic-assisted surgery and 193 patients who were cured by open surgery were followed up, and the rates of local recurrence, metastasis, implantative, and survival were contrasted and analyzed. Results Three years after laparoscopic-assisted surgery and open surgery, the disease-free survival rate was 86.2% （187/217） and 85.5% （165/193）, respectively, and the overall survival rate was 91.2% （198/217） and 92.7% （179/193）, respectively, the difference between the two groups was not statistic significance（P＞0.05）. The differences of the rates of local recurrence, metastasis, and implantative between the two groups were not statistic significance（P＞0.05）. Conclusions Laparoscopic-assisted surgery is similar with open surgery in the rates of local recurrence, forward metastasis, and overall survival. So laparoscopic-assisted surgery is a safe and radical curative surgery.
Abstract： Objective To evaluate the clinical significance of bilateral supraclavicular lymph node dissection after esophagectomy for patients with intrathoracic esophageal carcinoma. Methods A total of 197 patients with esophageal carcinoma but no obvious supraclavicular lymph node metastasis who underwent esophagectomy in Zhongshan Hospital of Xiamen University from March 1997 to September 2004 were included in this study. All the patients were divided into 2 groups， the control group and the study group. In the control group (non-supraclavicular lymphadenectomy group)， there were 96 patients including 62 males and 34 females with their age of 40-69 （55.2±3.1） years， who received 2-field lymphadenectomy (intrathoracic lymphatic drainage area and left paracardial lymph nodes) without supraclavicular lymph node dissection. In the study group (supraclavicular lymphadenectomy group)， there were 101 patients including 68 males and 33 females with their age of 41-68 （53.8±4.5） years， who received 3-field lymphadenectomy including intrathoracic lymphatic drainage area， left paracardial lymph nodes and bilateral supraclavicular lymph node dissection. Postoperative survival rate， lymph node metastasis rate， anastomotic site recurrence rate， and long-term supraclavicular lymph node metastasis rate were compared between the 2 groups. Results The overall 5-year survival rate of all the patients was 39.59% （78/197）. There was no statistical difference in 5-year survival rate between the 2 groups ［37.50％ （36/96） vs. 41.58％（42/101）， P＞0.05］. However， the 5-year survival rate of the patients with esophageal carcinoma in the upper third of the esophagus in the study group was significantly higher than that of the control group ［38.10％（8/21） vs. 29.17％ （7/24）， P＜0.05］. The intrathoracic lymph node metastasis rate （14.58% vs. 12.87%）， abdominal lymph node metastasis rate （6.25% vs. 7.92%）and anastomotic site recurrence rate （5.20% vs. 5.94%）of the control group and study group were not statistically different （P＞0.05）. However， long-term supraclavicular lymph node metastasis rate of the study group was significantly lower than that of the control group （2.97％ vs. 8.33％， P＜0.05） Conclusion Bilateral supraclavicular node dissection can significantly increase postoperative survival rate and decrease long-term supraclavicular lymph node metastasis rate of patients with esophageal carcinoma in the upper third of the esophagus.
Objective To compare the clinical effect of continuous renal replacement therapy (CRRT) and intermittent hemodialysis (IHD) in the treatment of severe acute renal failure (ARF). Methods A hundred patients with severe ARF treated between May 2011 and December 2014 were chosen to be the study subjects. According to the order of admission, they were divided into control group and observation group with 50 patients in each. Patients of the control group underwent IHD, while those in the observation group underwent CRRT. Serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine clearance rate (Ccr), treatment effective rate and survival rate were compared between the two groups before and after the treatment. Results Scr, BUN and Ccr were all improved after treatment in both the two groups. However, Scr, BUN and Ccr in the observation group [(225.1±162.7) μmol/L, (14.2±9.3) mmol/L, (23.4±10.5) mL/min] were significantly better than those in the control group [(588.4±183.6) μmol/L, (29.1±10.4) mmol/L, (15.9±8.2) mL/min]. The treatment effective rate and patients’ survival rate in the observation group were respectively 60% and 70%, both significantly higher than those in the control group (40% and 52%) All the differences were significant (P<0.05). Conclusion CRRT is superior in the treatment of severe ARF with a higher survival rate of the patients, which is worthy of clinical promotion.
