Objective To explore the clinical application of function-preserving pancreatic surgery for treating pancreatic neuroendocrine neoplasms (pNENs).Methods Twenty-eight patients with pNENs treated by the function-preserving pancreatic surgery at Anhui Province Hospital from January 2002 to December 2015 were analyzed retrospectively.Results Among the 28 patients, enucleation surgery was performed in 18 cases, distal pancreatectomy was performed in 8 cases, and middle pancreatectomy was performed in 2 patients.Total average operation time was (197±68) min, and the blood loss was (106±99) ml.The postoperative pancreatic fistula was observed in 7 patients, seroperitoneum was in 4 patients, incisional infection was in 1 patient, pulmonary infection was in 2 patients, and all the patients were cured by conservative treatment.There was no death during perioperative period.The postoperative hospital stay was (13±6)d.Analysis of pathological examination and clinical symptoms showed that 24 cases were diagnosed as functional pNENs (including 23 with insulinoma and 1 with gastrinoma), and 4 cases were as non-functional pNENs.The tumor grade G1 was categorized in 19 cases, G2 was in 9 cases.The TNM was I stage in all patients.There were no vascular or nerve invasion or lymph node metastasis.The follow-up period ranged from 4 to 144 months.2 patients were lost, and other patients were all alive.No diabetes or hypoglycemia occurred.Conclusions The function-preserving surgery for pNENs was safe and feasible, especially for well-differentiated functional pNENs.

Objective To investigate the expression of STAT3 signaling pathway genes including Survivin and COX-2 in cholangiocarcinoma,as well as the relationship between expression of these genes and prognosis of patients with cholangiocarcinoma.Methods The tumor and normal tissue samples were respectively collected from 43 patients with cholangiocarcinoma and 12 patients with intra-and extrahepatic bile duct stones or hepatic duct injury in the Affiliated Provincial Hospital of Anhui Medical University from September 2007 to July 2012.The expression of STAT3,phosphorylated-STAT3 (p-STAT3),Survivin and COX-2 were examined using immunohistochemistry,and the relationship between the expression of these genes and the clinical pathological features and prognosis of patients with cholangiocarcinoma was analyzed.Patients were followed-up through outpatient examination and telephone interview until March 2014.Categorical data were analyzed using the chi-square test.Correlation analysis was done by Spearman's method.The survival curve was generated using the Kaplan-Meier method,and the survival analysis was conducted using the log-rank test.Results The positive expression rates of STAT3,p-STAT3,Survivin and COX-2 in the tumor samples were 69.8％ (30/43),65.1％ (28/43),72.1％ (31/43),79.1％ (34/43),respectively,which were compared with 41.7％ (5/12),8.3％ (1/12),16.7％ (2/12) and 41.7％ (5/12) in the normal tissue samples,showing a significant difference for the last 3 indexes (x2=12.136,9.811,4.679,P ＜ 0.05).Overexpression of p-STAT3,Survivin and COX-2 protein was correlated with lymph node metastasis (x2 =14.700,5.959,4.075,P ＜ 0.05).Overexpression of p-STAT3 was also related to neural invasion (x2=10.384,P ＜ 0.05).Expression of Survival and COX-2 protein was not associated with lymph invasion (x2=2.718,3.024,P ＞ 0.05).Expression of p-STAT3,Survivin and COX-2 was however not associated with gender,age and tumor location,differentiation and diameter (x2=0.148,0.720,1.835,1.040,0.236 ; 0.001,0.009,0.029,1.863,0.197 ; 0.433,0.686,0.002,2.974,0.029,P ＞ 0.05).Expression of Survivin and COX-2 protein was positively correlated to p-STAT3 protein (r =0.524,0.583,P ＜ 0.05).All the 43 patients were followed up for 6-60 months.Among the 17 patients with hilar cholangiocarcinoma,the median survival time was 7,9,9 months for patients with positive expression of p-STAT3,Survivin and COX-2 protein,compared with 18,11 and 11 months for patients with negative expression of these proteins.The survival rates of the patients with positive and negative expression of p-STAT3 protein were 33.3％ and 68.6％,respectively,with a statistical significance for p-STAT3 protein (x2=12.916,P ＜ 0.05).Of the remaining 26 patients with common bile duct carcinoma,the median survival time was 9,10 and 9 months for patients with positive expression of p-STAT3,Survivin and COX-2 protein,compared with 20,20 and 20 months for patients with negative expression of these proteins.The survival rates of the patients with positive expression of p-STAT3,Survivin and COX-2 protein were 20.8％,9.4％ and 8.5％,which were lower than 37.5％,37.5％ and 50.0％ of patients with the negative expression of these proteins,with a statically significance for all the 3 proteins (x2=12.787,6.245,11.161,P ＜ 0.05).Conclusions The p-STAT3,Survivin,COX-2 proteins are highly expressed in the cholangiocarcinoma and the expression levels of these proteins are positively correlated.The survivin and COX-2 may be the downstream genes of STAT signaling pathway,which are involved in the progression and prognosis of cholangiocarcinoma.

Objective To investigate the short and long-term outcomes and risk factors after open surgery or and endoscopic hepatolithotomy for hepatolithiasis. Methods A retrospective study was made on cases of hepatolithiasis who underwent hepatolithotomy by open surgery or endoscopically from Jan 2001 to Dec 2008.Of 254 patients,189 were followed-up including 127 after open surgery and 62 endoscopically.The univariate and multivariate analyses were performed to determine the risk factors. Results Complete stone clearance was achieved in 85.0 ％ ( 108/127 ) of open surgery including hepatecomy,61.3 ％ ( 38/62 )of endoscopic treatment.After a median follow-up period of 6.0 years (2.5 to 10.5 years),stone recurred in 32.8％ (62/189) of patients,biliary cirrhosis in 7.4％ ( 14/189),cholangiocarcinoma in 7(3.7％ ),all cancer cases were dead with a mortality rate of 7(3.7％ ).Bile duct stricture (OR:7.522,95％ CI:2.642 -21.415),stones in both lobes (OR:11.630,95％ CI:3.989 -33.912),and endoscopic treatment ( OR:21.374,95％ CI:6.713 - 68.056 ) were independent risk factors ( P ＜ 0.05 ) for incomplete stone clearance by unconditional Logistic regression analysis.In addition,recurrent stones and/or cholangitis were associated with residual stones ( OR:3.059,95％ CI:1.307 - 7.159),stricture ( OR:3.702,95％ CI:1.567-8.745) and endoscopic therapy (OR:4.841,95％ CI:1.946 - 12.043) (P ＜ 0.05).Conclusions Stricture,stone in both lobes and endoscope therapy were independent risk factors for residual stones; Residual stones,bile duct stricture and endoscope therapy were independent risk factors for recurrent stones and/or cholangitis.

Objective: To observe the effects of tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder on pain and shoulder joint function in subacromial impingement syndrome (SIS). Methods: Eighty patients with SIS were recruited and divided into a control group and a treatment group by the random number table method, with 40 cases in each group. The control group was given JIN's three-needle therapy for the shoulder, and the treatment group received additional tendon-regulating and stretching manipulation. The visual analog scale (VAS) score and constant-Murley score (CMS) were observed before and after the intervention, and the total effective rate was also observed. Results: The total effective rate was 92.5％ in the treatment group versus 70.0％ in the control group, and the difference was statistically significant (P<0.05). The VAS score and CMS changed notably after treatment in both groups (P<0.05), and the improvements were markedly greater in the treatment group than in the control group (P<0.05). Conclusion: Tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder can facilitate the relief of pain and the improvement of shoulder joint function in SIS patients.

Objective To summarize the experience of diagnosis and treatment for pancreatic neuroendocrine neoplasms (pNENs).Methods Forty-seven patients with pNENs who were treated at Anhui Province Hospital during January 2002 to December 2013 were retrospectively analyzed.They were followed by telephone or clinic interview,and the deadline date was January 31st,2014.Survival was analyzed with the Kaplan-Meier method,and the prognostic factors for survival were identified.Results Among the47 patients,there were 13 males and 34 females,aged from 16 to 74 years old,with a median age of 45 years,There were 17 cases of non-functioning pNENs,30 cases of functioning pNENs.The detection rate of B ultrasound,CT,MRI was 71.8％ (28/39),92.7％ (38/41),75.6％ (6/8).Forty-six patients underwent radical surgery,and 1 patient underwent palliative surgery.The pathologic type included 41 cases of pancreatic neuroendocrine neoplasms,6 cases of neuroendocrine cancer.There were 22,19,6 cases of grade G1,G2,G3 lesions,respectively.There were 32,11,4 cases of TNM staging Ⅰ,Ⅱ,Ⅲ,respectively.Vascular structure was invaded in 15 cases,and nerve was invaded in 18 cases.Lymph node was examined in 15 cases,and 5 were found to have metastatic lesion.After surgery,pancreatic fistula occurred in 9 patients,ascites in 4 patients,wound infection in 4.The follow-up period ranged from 2 to 144 months.The overall 1,3,5-year survival rates were 94.9％,88.4％,and 84.4％.The 5-year survival rates of patients with grade G1,G2,G3 were 100％,73.3％,60％;and the 5-year survival rates of patients with TNM staging Ⅰ,Ⅱ,Ⅲ were 100％,70.0％,33.3％.It was showed that TNM staging system,WHO classification,lymph node metastasis,vascular and neural invasion were associated with the prognosis.Conclusions CT is the imaging test of choice for pNENs,while surgery is the first choice for treatment.Surgical resection of pNENs results in long-term survival.TNM staging,WHO classification,lymphatic metastasis,vascular and neural invasion are closely related to the prognosis of pNENs.

Objective To evaluate the treatment of gastroentero-pancreatic neuroendcorine neoplasms with liver metastasis.Methods Two gastroentero-pancreatic neuroendcorine neoplasms with liver metastases treated at Anhui Provincial Hospital Affliated of Anhui Medical University were analyzed retrospectively.Results In first patient liver metastases from duodenal papilla neuroendocrine neoplasm was treated by four courses of TACE until the liver metastases completely disappeared.The patient then underwent pancreaticoduodenectomy to eradicate the primary tumor.The patient was followed up for 2 years and was doing well.In second patient, liver metastasis, noted four years after distal pancreatectomy for a neuroendocrine tumor, was initially managed by high dosage of octreotide and sunitinib.After these attempts failed, the patient received a liver transplantation four years ago and was followed up until March 1, 2015 without tumor recurrence.Conclusion Liver metastasis of gastroenteropancreatic neuroendcorine neoplasms responds positively to liver transplant with pretty good prognosis.

Objective To explore the effects of Yishen Capsule on the soluble endothelium protein C receptor (sEPCR) and P-selectin (CD62P) as well as the serum levels of immunoglobulin (Ig) and complement 3 (C3) in patients with chronic glomerulonephritis (CGN). Methods The changes of sEPCR and CD62P levels in plasma as well as Ig and C3 levels in serum were assessed in 40 normal subjects and 78 patients before and after treatment by double-antibody enzyme-linked immunosorbent assay, flow cytometry and immunoturbidimetry, respectively. Results Compared with those in normal group before treatment, the levels of sEPCR and CD62P in plasma as well as IgA in serum increased obviously (P<0.01), and the levels of IgG and IgM as well as C3 in serum decreased significantly in CGN patients (P<0.01). After three months' treatment with Yishen Capsule, the levels of sEPCR and CD62P in plasma and IgA in serum decreased significantly (P<0.05 or P<0.01), and the levels of IgG and IgM in plasma as well as C3 in serum increased obviously (P<0.05 or P<0.01). Conclusion The mechanism of Yishen Capsule's effect in treating patients with CGN may be correlated with decreasing sEPCR and CD62P levels in plasma as well as regulating the levels of Ig in serum and C3.

Objective To explore the effects of early hospital-family comprehensive rehabilitation on the development of pretenn infants. Methods A total of 256 premature infants were chosen and divided into an early intervention group (n = 148) and a control group (n =108). Besides being given the conventional mothering instruction , the early intervention group was given early assessment, regular visits and hospital-family comprehensive rehabilitation treatment. The control group was only given the conventional mothering instruction. The fine and gross motor growth quotients, adaptation, verbalisation and social behavior and general growth quotient of all the premature infants were assessed periodically using the infant neuropsychology growth scale. Results The growth quotient assessment indicators of the infants receiving the intervention were obviously better at the 6th, 12th, 18th and 24th month after birth, and the differences between the two groups were statistically significant. The incidence of cerebral palsy in the early intervention group was 0.71% (1/148), with only one cerebral palsy infant in the early intervention group who was at level Ⅲ of the gross motor function classification system ( GMFCS) , while the incidence of cerebral palsy in the control group was 5.1% (5/98) , with 5 cerebral palsy infants, one of whom was at GMFCS level Ⅲ and 4 of whom were at level Ⅳ. Conclusions Early systematic hospital-family comprehensive rehabilitation can improve the general growth of premature infants, decrease the incidence of cerebral palsy, and neurobehavior deficits.
