Objective To investigate the effect of left lateral segmentectomy combined with fiber choledochoscope for hepatobiliary calculus.Methods Eighty-seven patients with hepatobiliary calculus who underwent hepatectomy from December,1998 to December,2008 were reviewed retrospectively.Forty-six patients underwent the section of common bile duct to remove calculus combined with left lateral segmentectomy and fiber choledochoscope( Group A),41 patients underwent left hepatectomy and section of common bile duct to remove calculus( Group B).The postoperative stone residual rate,complications and long-term outcome were compared between the two groups.Results The postoperative stone residual rate of either group was zero.Intraoperative bleeding ( 401.1 ± 180.4ml) ,operative times ( 202.5 ±36.6 rmin) of group A were significantly lower than those of the group B (515.9 ± 200.6ml and 257.3 ± 42.9min) ( P ＜ 0.001 and 0.01,respectively) .Hospital stays of group A was lower than that of group B,but this is no statistical significance ( P ＞ 0.05 ) .The incidence of postoperative complications were similar in the two groups( 15.2% v.s.24.4% ,P ＞ 0.05 ).The effective rates of the two groups were similar (91.3 % VS 92.7 %,P ＞ 0.05 ).Conclusions The long-term and short-term outcome of left lateral segmentectomy combined with fiber choledochoscope for hepatobiliary calculus is similar to that of left hepatectomy ,and can successfully shorten the hospital stay and reduce the hospital fee.

Objective To observe the effect of electroacupuncture(EA) on the hippocampal expression of GluA1,pGluA1,CaMK Ⅱ and pCaMK Ⅱ in rats with vascular dementia(VD),so as to find out the underlying mo lecular mechanisms of EA in treating VD.Methods Thirty-two Wistar rats were randomly divided into a shamoperation group,a model group,a sham-acupuncture group,and an EA group (8 in each group).Permanent bilateral common carotid artery occlusion was performed to model vascular dementia in the model group,the shamacupuncture group and the EA group,while exposure but no occlusion of the bilateral common carotid were performed in the sham-operating group.Novel object recognition test was adopted to prove the establishment of VD rat model.All the rats were kept in an immobilization apparatus while receiving treatments.EA was applied ontoBaihui (GV20) and Zusanli (ST36) in EA group for 30 min,once daily for 7 days.Sham-acupuncture group were treated with needles inserted 0.5 mm superficially.And the sham-operation group and the model group were only immobilized.The protein expression of GluA1,pGluA1,CaMK Ⅱ and pCaMK Ⅱ in hippocampal tissue was detected by western blotting.Results The expression of GluA1 in the model group (1.216 ± 0.102) was significantly less than in the sham-operating group (1.918 ± 0.137) (P ＜ 0.05).The expression of GluA1 in the EA group (1.653 ± 0.169) was significantly higher than in the model group (1.216 ± 0.102) and in sham-acupuncture group (1.231 ±0.188) (P＜0.05).The expression of CaMKⅡ in the model group (1.516±0.392) was less than in the sham-operating group (2.187 ± 0.231) (P ＜ 0.05).The expression of CaMK Ⅱ in the EA group (2.733 ±0.387) was significantly higher than in the model group (1.516 ±0.392) and sham-acupuncture group (1.493 ±0.205) (P＜0.05).The expression ofpGluA1 in the model group (1.502 ±0.419) was less than in the sham-operating group (2.253 ± 0.244) (P ＜ 0.05).The expression of pGluA1 in the EA group (2.382 ± 0.308) was significantly higher than in the model group (1.502 ± 0.419) and the sham-acupuncture group (1.498 ± 0.223) (P ＜ 0.05).The expression of pCaMK Ⅱ in the model group (0.394 ± 0.227) was less than in the sham-operating group (0.667 ±0.175) (P＜0.05).The expression ofpCaMKⅡ in the EA group (1.189± 0.346) was significantly higher than in the model group (0.394 ± 0.227) and the sham-acupuncture group (0.408 ± 0.231) (P ＜ 0.05).Conclusion EA can enhance the protein expression and phosporylation of GluA1 and CaMK Ⅱ,causing silent synapses transforming into functional synapses,and consequently,long term potentiation was facilitated and cognitive impairment was improved by EA.

Objective To explore the role of apoptosis and the expression of X-linked inhibitor of apoptosis protein(XIAP) in polymorphonuclear neutrophils(PMNs) during acute pancreatitis(AP).Methods Blood from normal control(NC,n=15),mild acute pancreatitis(MAP,n=15) and severe acute pancreatitis(SAP,n=15) were collected.PMNs apoptosis was detected by flow cytometry.PMNs were isolated from each group and XIAPmRNA and protein levels were assessed by RT-PCR and Western Blotting.Results PMNs apoptosis in SAP group was(2.15?0.40)%,MAP group was(4.16?0.14)%,NC group was(4.31?0.12)%.PMNs apoptosis rate in SAP and MAP groups was decreased compared to NC group(P

Objective To analysis the clinical features of dorsal pancreas agenesis ( DPA) and the associated diabetes, pancreatitis and other congenital organ malformations.Methods Chinese databases of Sinomed, CQVIP and CNKI using the term of short pancreas, pancreas agenesis, bulbar pancreas and dorsal pancreas, and English databases of PubMed using the term of dorsal pancreas agenesis, short pancreas and pancreas hypoplasia were searched.The clinical manifestation, pancreatic head characteristics and associations with diabetes, pancreatitis and other congenital organ malformations were analyzed.Results Six related publications from Chinese databases were searched and 21 patients were included with 2 cases excluded.Sixty-one publications from English database were searched and 71 patients were included.Thus, a total of 91 patients with DPA were analyzed.Abdominal pain was the most common manifestation, which was reported by 61.5% of the patients. 15.3% patients were identified during regular physical examination. Other manifestations including jaundice, fatigue, abdominal discomfort and diabetes were rare.After removing cases with insufficient information, 39 patients (61.9%) carried abnormal pancreatic head.Prevalence of diabetes or impaired glucose tolerance was 56.7% and the percentage of insulin-dependent diabetes in patients with abnormal glycaemia was 47.3%(n=18).20 patients (26.7%) were associated with pancreatitis, including 15 patients (75.0%) with acute pancreatitis, 1 patient (5.0%) with recurrent pancreatitis, and 4 patients (20.0%) with chronic pancreatitis. Thirty-three patients ( 36.2%) suffered other congenital organ malformations, including 21 patients (63.6%) with splenic malformation, 8 patients (24.2%) with heart malformation, and 17 patients (51.5%) with multi-organs malformations like gastrointestinal malformation, azygos vein and inferior cava vena fusion, duodenal and biliary atresia and renal absence.Conclusions The main diagnostic criteria of DPA was the absence of dorsal pancreatic duct.Diabetes was the most common complication followed by pancreatitis.

Objective To investigate the application value of magnetic-controlled capsule endoscopy (MCE) for gastric diseases in physical examination of asymptomatic population.Methods Data of 211 asymptomatic individuals who received MCE examinations from July 2015 to December 2016 in Changhai Hospital were collected and rctrospectively analyzed.The tolerance and safety of MCE were studied by analyzing the detection rate for the focal lesions and the rate of endoscopy transfer.Results Among 211 patients,the detection rate of the gastric focal lesions was 9.5％ (20/211).The detection rate in male was higher than that in female (P＜0.05).All patients completed MCE examination successfully and no adverse event was reported.Conclusion MCE,a non-invasive endoscopic modality,is safe and better tolerated than conventional endoscopy,and can be used as a promising approach to screening the gastric diseases in asymptomatic population due to high detection rate of these diseases.

Objective : To compare the clinical effect of the tunnel technique (TUN) and vestibular incision subperiosteal tunnel access (VISTA) combining connective tissue grafts (CTGs) on recovering the exposed root surface in a case of gingival recession over the upper anterior teeth and then to provide clinical evidence for gingival recession treatment. Methods: A case of gingival recession (Miller I type) over teeth 13-14 and 22-23 was treated using different techniques bilaterally. 22-23 were treated by a TUN combined CTG transplantation,while teeth 13-14 were treated by a VISTA technique combined with CTG transplantation. The gingival retraction height (GRH), gingival retraction width (GRW), keratinized gingival width (KW), root coverage aesthetic score (RES) and visual analog scale (VAS) were measured after operation. Results : The effect of post-operation were ideal and complete ginglval recovering were achieved, the postoperative effects of the two methods were stable, GRH and GRW decreased, and KW increased. RES was 10. The VAS score of VISTA combined with CTG transplantation was 6, which was higher than that of TUN+CTG. Conclusion Gingival recession can be treated by TUN+CTG or VISTA+CTG with ideal prognosis. VISTA with an additional incision facilitates the operative procedure but leads to less comfort.

Objective:Based on the previous animal experiments, to preliminarily explore the safety and efficacy of self-developed new smartphone-controlled vibrating capsule (VC) in the treatment of patients with functional constipation (FC).Methods:At the Outpatient Department of Gastroenterology, Changhai Hospital, Naval Medical University, 24 patients with FC were prospectively enrolled. The trial process included basic period for ≥two weeks, treatment period for six weeks, and follow-up visits ≥six (once every two weeks). During treatment period, the patients were assigned into sham capsule group, VC at low frequency mode group and VC at high frequency mode group and the patients swallowed 12 corresponding capsules. The safety of VC treatment was evaluated based on the observation the occurrence of adverse events (AE) in patients of three groups, which included abdominal pain, abdominal distention, capsule retention and abnormal laboratory indicators. The efficacy of VC treatment was assessed by comparison of the patients of three groups in mean complete spontaneous bowel movements (CSBM) per week, mean spontaneous bowel movements (SBM) per week, capsule discharge time, patient assessment of constipation quatity of life questionnaire (PAC-QOL), patient assessment of constipation symptom questionnaire (PAC-SYM). Chi-square test, least significant difference- t test, Kruskal-Wallis test, Wilcoxon rank sum test and Fisher exact test were used for statistical analysis. Results:Two patients were lost in follow up. In the end, seven, eight and seven patients were enrolled in sham capsule group, VC at low frequency mode group and VC at high frequency mode group. AE occurred in three patients. At the sixth week of treatment, the difference between average CSBM in one week and baseline of sham capsule group, VC at low frequency mode group and VC at high frequency mode group was 0.0 (0.0, 2.0), 2.0 (1.0, 2.8) and 1.0 (0.0, 5.0), respectively; and the difference between average SBM in one week and baseline of sham capsule group, VC at low frequency mode group and VC at high frequency mode group was -1.0 (2.0, 2.0), 1.0 (-0.8, 2.0) and 1.0 (0.0, 4.0), respectively. During the six weeks of treatment period, the difference between mean CSBM per week and baseline of three, seven and five patients of sham capsule group, VC at low frequency mode group and VC at high frequency mode group was more than one, and the difference between SBM per week and baseline of two, five and five patients was more than one. At the sixth week of treatment, capsule discharge time of VC at low frequency mode group and VC at high frequency mode group was shorter than that of sham capsule group ((65.7±9.3) and (59.1±3.4) h vs. (96.7±10.0) h), and during the whole treatment period capsule discharge time of VC at low frequency mode group and VC at high frequency mode group was shorter than that of sham capsule group ((63.6±8.6) and (59.8±6.6) h vs. (100.5±13.1) h), and the differences were statistically significant ( t=3.119, 3.584, 2.832 and 3.036, all P<0.05). The PAC-SYM score of patients of sham capsule group, VC at low frequency mode group and VC at high frequency mode group during the period of treatment was 14.3±2.0, 9.9±2.3 and 7.0±2.0, respectively, there were no statistically significant differences among the three groups ( P>0.05). The PAC-QOL score of patients of sham capsule group, VC at low frequency mode group and VC at high frequency mode group during the period of treatment was 31.3±4.4, 24.0±3.8 and 13.9±4.1, respectively, and the PAC-QOL score of VC at high frequency mode group was lower than that of sham capsule group, and the difference was statistically significant ( t=2.808, P=0.012), however, there was no statistically significant difference in the PAC-QOL score between VC at low frequency mode group and sham capsule group, and between VC at high frequency mode group and VC at low frequency mode group (both P>0.05). Conclusions:VC can be safely used in patients with FC, which can promote defecation and relieve the symptoms of constipation. However, there is no significant difference in the therapeutic effect of capsules with different vibration frequencies.

Objective To analyze the optimal timing of endoscopic stone extraction combined with extracorporeal shock wave lithotripsy (ESWL) in the treatment of chronic pancreatitis (CP) with pancreatic stones. Methods Data regarding 170 pancreatic stone patients receiving ESWL and endoscopic stone extraction at Shanghai Changhai Hospital from February 2014 to February 2015 were retrospectively analyzed. Based on the the prior history of endoscopic treatment,patients were divided into group A and B,and then sub-divided into three groups according to the timing of endoscopic intervention after ESWL including <12 h,12~36 h and >36 h subgroup. The success of pancreatic ductal cannulation, clearance of stone in the main pancreatic duct, and ERCP-related complications were evaluated. Results Among all the enrolled 170 patients,107 previously received ERCP(group A) while the others didn't(group B). The overall success rate of cannulation and clearance rate of stones at different times showed no significant difference. The success rate and clearance rate in group A in <12 h,12~36 h and >36 h subgroup were 91.7%,95.2%,78.0%,and 91.7%,95.2%,80.0%,and no significant difference existed. In group B, the success rate and clearance rate in <12 h, 12~36 h and >36 h subgroup were 66.7%, 71.4%, 96.3%, and 60.0%, 76.2%, 92.6%, and the differences were statistically different. The success rate and clearance rate of >36 h subgroup in group B were obviously higher than that in <12 hours (P=0.025) and 12~36 h subgroup (P=0.04). The timing of endoscopic stone extraction did not influence ERCP-related complications. Conclusions Early endoscopic stone extraction after ESWL can be considered in patients with pancreatic stones who previously underwent ERCP. Delayed endoscopic stone extraction after ESWL is recommended in patients without prior ERCP,which can help promote the therapeutic efficacy.
