Objective To evaluate the role of procalcitonin in patients with different severity grades of acute cholangitis (AC).Methods A retrospective study was carried out on 147 patients with different severity grades of AC who were treated from May 2012 to November 2013 at the Dongyang People's Hospital.Results Of 147 patients,the PCT concentrations were (165.63 ± 32.67) pg/ml,(348.97 ± 45.78) pg/ml,(758.91 ± 28.94) pg/ml for patients with mild,moderate and severe AC respectively.The PCT concentrations were significantly higher in patients with severe AC than those with moderate AC (P ＜ 0.05),and also in patients with moderate AC than those with mild AC (P ＜ 0.05).The top three bacteria obtained from blood culture from the different severity grades of AC showed no significant diferences (P ＞ 0.05).Conclusion Serum PCT concentrations were elevated in patients with AC and it may be used as a parameter to assess the severity of AC.

Objective To evaluate the clinical significance of juxtapaillary duodenal diverticula (JPDD) in patients of acute calculous cholangitis (AC) with different severity grade.Methods A retrospective analysis was carried out for 488 AC cases of different severity from January 2011 to December 2013 who underwent duodenoscopy in Dongyang People's Hospital.Results Of the 488 patients, the JPDD was found in 2.87％, 6.15％ and 4.10％ in patients with mild, moderate and severe AC, respectively.The prevalence of JPDD in severe AC were significantly higher in the moderate and mild AC (x2 =4.486, P =0.034;x2 =14.686, P ＜ 0.001);Procalcitonin (PCT) concentrations in severe AC of JPDD were significantly higher in moderate and mild AC of JPDD (t =10.420 9, P ＜ 0.001;t =4.870 4, P ＜ 0.001).The cannulation failure rate and the amylase were significantly higher in JPDD patients compares to patients without JPDD (x2 =36.95, P ＜ 0.001;t =8.29, P ＜ 0.001).Conclusions JPDD detection rate increases with aging and seems to be associated with acute cholangitis (AC) with different severity grade and PCT concentration.JPDD predicts a higher cannulation failure rate and the amylase level after duodenoscopy.

Objective:To discuss the effect of pharmacist intervention on the use of antimicrobial agents in the clinical pathway of community-acquired pneumonia ( CAP) in our hospital to standardize the rational medication and promote the rational use of antimicro-bial agents. Methods:Totally 100 bacterial CAP patients in 2013 ( before the intervention) and 2014 ( after the intervention) in the pneumology department were studied. The antibacterial drug cost, total hospitalization cost, use intensity of antimicrobial drugs, hospi-talization time, therapeutic effects and so on in the two groups were observed during the treatment. Results: There were significant differences between the two groups in antibacterial drug cost, total hospitalization cost, use intensity of antimicrobial drugs, hospitaliza-tion time and so on, whereas there was no significant difference in the curative effect. Conclusion:After the pharmacist intervention, the application of antibiotics is more rational, the antibiotics use density and per capita cost are reduced, the hospitalization day is shortened and the value of pharmacists is also improved.

Objective To evaluate the clinical significance of different localizations of juxtapaillary duodenal diverticula of patients with endoscopic retrograde cholangiopancreatography for pancreaticobiliare disease.Methods We studied patients in whom juxtapaillary duodenal diverticula was detected during endoscopic retrograde cholangiopancreatography form January 2010 to April 2016 in Department of Hepatobiliary Surgery,Dongyang People's Hospital of Zhejiang Province.The influence of juxtapaillary duodenal diverticula on the success rate of endoscopic retrograde cholangiopancreatography and the incidence of associated complications was analyzed.Measurement date were represented as ((x) ± s) comparison between the groups was analyzed by the t test.Count date were evaluated by the frequency and percentage,comparison between the groups was analyzed by the chisquare test or Fisher exact probability method.Results Juxtapaillary duodenal diverticula were present in 67 (14.11％) of the 475 patients undergoing endoscopic retrograde cholangiopancreatography for various indictions.Of the 67 patients,38 (56.72％) patients were peridiverticular papilla and 29 (43.28％) patients were intradiverticular papilla.The presence of cannulation success on first attempt was signicantly different between juxtapaillary duodenal diverticula group and non-juxtapaillary duodenal diverticula group(P =0.022),whereas the presence of c annulation success on total attempt was no-different between two groups(P =0.086).The presence of cannulation success on first attempt and total attempt was signicantly different between peridiverticular papilla group and intradiverticular papilla group(P =0.002,P =0.001).The presence of post-ERCP pancreatitis and bleed were more frequently in juxtapaillary duodenal diverticula group (P =O.023,P =0.003),but the different was non-signicantly between peridiverticular papilla group and intradiverticular papilla group (P =1.000,P =1.000).Conclusion Juxtapaillary duodenal diverticula detection rate and different location increase the difficulty of endoscopic retrograde cholangiopancreatography and maybe increase the presence of complications.

Objective To discuss the feasibility of laparoscopic simple oblique side-to-side duodenoduodenostomy in treating congenital annular pancreas in neonates.Methods Medical records of neonates with the diagnosis of congenital annular pancreas undergoing laparoscopic simple oblique side-to-side duodenoduodenostomy at Huai'an Women and Children's Hospital from January 2015 to May 2017 were reviewed.The age ranged from 1 d to 4d with a median age of 2d at operation.The body weight at operation was 2.5-3.5 kg with a mean of 3.1 kg.By a lower-pressure pneumoperitoneum of 5-8 mmHg (1 mmHg =0.133 kPa) and a suspending suture for liver elevator,the procedure was performed using 4 ports.A transumbilical 5-mm port was for the laparoscopy and 3 3-mm trocars were placed for inserting instruments.The diagnosis was made after laparoscopic exploration,and then the distal duodenum was incised longitudinally 0.5-1 cm away from the annular pancreas,the proximal duodenum was incised O.5 cm away from the annular pancreas obliquely.The duodenoduodenostomy was performed as a "simple oblique" side-to-side anastomosis with 5-0 PDS running suture.Results All the 6 cases were treated by laparoscopic simple oblique side-to-side duodenoduodenostomy.Three of cases were annular pancreas complicated with congenital intestinal malrotation,and Ladd's procedure was accomplished in the mean time.The average operative time was 98 min (70-120 min).The blood loss during operation was 3-10 ml.Fluid diet started on postoperative day 3 to 7 (mean 4.5 d),without abdominal distention and vomit,and all the cases were discharged uneventfully in a median of 7-14 (mean 9 d) postoperative day without any postoperative complications.No cases were transferred to open abdominal surgery,and there were no intraoperative and postoperatuve adverse events.The cases were followed-up for 1-30 months (mean 13 months),and all the cases grew well without intestinal obstruction.Conclusions The laparoscopic simple oblique duodenoduodenostomy in treating congenital annular pancreas was conveniently performed,the intestinal function recovered quickly,which can be safely done in neonatal period even if the neonate was complicated with congenital intestinal malrotation.

Objective:To investigate whether endogenous hydrogen sulfide (H2 S)was involved in the pathogenesis of osteoarthritis (OA)and its underlying mechanism,to detect H2 S and its synthases ex-pression in knee cartilage in patients diagnosed with different severity of OA,and to explore the transcrip-tion and expression of gene MMP-13 in chondrocytes treated with IL-1βor H2S.Methods:Synovial fluids of the in-patients with different severity of OA hospitalized in Peking University First Hospital were collected for measurement of H2 S content using methylene blue assay.Articular cartilages of the patients who underwent knee arthroplasty were collected for the cell culture of relatively normal chondrocytes.The chondrocytes were cultured to the P3 generation and H2 S molecular probes were used for detection of endogenous H2 S generation in the chondrocytes.Immunocytochemistry was used to detect the localization of H2 S synthases including cystathionine β-synthase (CBS),cystathionine-γ-lyase (CSE),and mercap-topyruvate sulfurtransferase (MPST)in OA chondrocytes.Western blot was used to quantify the protein expressions of CSE,MPST,and CBS in cartilage tissues of the patients who were diagnosed with OA and underwent knee arthroplasty.The relatively normal human chondrocytes were cultured to passage 3 and then divided into 4 groups for different treatments:(1 )the normal control group,no reagent was added;(2)the IL-1βgroup,5 μg/L of IL-1βwas added;(3)the IL-1β+H2S group,200 μmol/L of NaHS was added 30 min before adding 5 μg/L of IL-1β;(4)the H2 S group,200 μmol/L of NaHS was added. The transcription and expression of gene MMP-13 in chondrocytes of each group were determined with Real-time PCR and Western blot,respectively.And the total NF-κB p65 and phosphorylated NF-κB p65 in chondrocytes were detected with Western blot.Results:The content of H2 S in the synovial fluid of degenerative knee was (14.3 ±3.3)μmol/L.Expressions of endogenous H2 S and its synthases including CBS,CSE and MPST were present in the cytoplasm of chondrocytes.CSE protein expression in Grade 3 (defined by outerbridge grading)cartilage tissues was significantly increased as compared with that of Grade 1 cartilage tissues (1.67 ±0.09 vs.1.26 ±0.11,P<0.05).However,no significant difference of CBS or MPST expression among the different groups was observed.The expression of MMP-13 protein in the IL-1βgroup was significantly higher than that in the normal chondrocytes (1 .87 ±0.67 vs.0.22 ± 0.10,P<0.05 ),and that in the IL-1β+H2 S group was significantly decreased than that in the IL-1βgroup (0.55 ±0.11 vs.1.87 ±0.67,P<0.05),and that in the H2S group had no significant difference compared with that in the normal control group.The transcription of MMP-13 protein in the IL-1βgroup was significantly higher than that in the normal chondrocytes (31.40 ±0.31 vs.1.00 ±0.00,P<0.05), and that in the IL-1β+H2 S group was significantly decreased than that in the IL-1βgroup (24.41 ± 1.28 vs.31.40 ±0.31,P<0.05),and that in the H2S group had no significant difference compared with that in the normal control group.The total NF-κB p65 in the IL-1βgroup was significantly higher than that in the normal chondrocytes (2.13 ±0.08 vs.0.73 ±0.08,P<0.05),and that in the IL-1β+H2S group was significantly decreased than that in the IL-1βgroup (1 .24 ±0.13 vs.2.13 ±0.08,P<0.05 ),and that in the H2 S group had no significant difference compared with that in the normal control group.The phosphorylated NF-κB p65 in IL-1βgroup was significantly higher than that in the normal chondrocytes (1.30 ±0.13 vs.0.19 ±0.04,P<0.05),and that in IL-1β+H2S group was significantly decreased than that in the IL-1βgroup (0.92 ±0.26 vs.1.30 ±0.13,P<0.05),and that in the H2S group had no significant difference compared with that in the normal control group.Conclusion:H2 S affected the cartilage degeneration by partly inhibiting the degradation of extracellular matrix.

Objective To explore the clinical value of portal exposure in laparoscopic treatment of children with type Ⅲ biliary atresia (BA).Methods From June 2013 to October 2017,30 infants with type Ⅲ BA who treated with laparoscopic portoenterostomy in Huai'an Women and Children's Hospital were selected.A percutaneous suture was used to snare the round ligament and retract the liver,other percutaneous stay sutures were then introduced and fundus and neck of gallbladder were sutured to elevate the liver to expose the portal hepatis.The fibro cord and hepatic vessels were mobilized,and then two rubber bands were put around the left and right portal veins and hepatic arteries.The portal hepatis was exposed by laterally stretching the two elastic rubber bands.The fibro cord was removed and then laparoscopic portoenterostomy was accomplished.In 20 cases,the liver was enlarged,part of hepatic lobus quadratus was removed laparoscopiclly for exposure of the portal hepatis.Results There were 30 cases in this group,2 cases were converted to open surgery by a micro transverse incision.There was no surgical death.Time of laparoscopic procedure varied from 210 to 280 min.All cases survived the surgery without any intraoperative complications.Blood loss during operation was minimal,without necessity for blood transfusion.One case died of respiratory failure one week after surgery.Two cases were lost follow-up.Twenty-five cases were followed up for 3～51 months(mean 22.4 months).Three cases died because of repeated cholangitis and liver failure at 10,16,35 months postoperatively.Nineteen patients' total bilirubin had dropped to normal,three others' bilirubin levels dropped significantly after surgery.Conclusion The technique of laparoscopic hepatic porta exposure can help to complete hepatic portoenterostomy successfully,reduce the conversion rate of laparoscopic surgery,and improve the surgical effect.

Objective:To explore the possibility of laparoscopic simple oblique duodenoduodenostomy in the management of congenital duodenal obstruction in neonates.Methods:The clinical data of neonates with congenital duodenal obstruction undergoing laparoscopic simple oblique duodenoduodenostomy at Huaian Women and Children′s Hospital from February 2015 to February 2018 were retrospectively reviewed.By a lower-pressure pneumoperitoneum of 5-8mmHg and a suspending suture for right liver elevator, the procedure was performed using 4 ports: a transumbilical 5-mm port for the camera and another three 3-mm ports for instruments.After kocherizing of the proximal and distant part of the duodenum, the lower duodenum was incised longitudinally 0.5-1cm distal to the blocked end, the upper duodenum incision was placed 0.5cm away from the blocked end extended downward obliquely.The duodenoduodenostomy was performed as a " simple" " oblique" anastomosis with 5-0 PDS suture.Results:Fifteen patients were identified with a median age at operation of 2 days.Of all the cases, 4 cases were duodenal atresia (type Ⅲ), 11 cases were annular pancreas, and 7 cases of them were annular pancreas complicated with congenital intestinal malrotation.All cases were treated with laparoscopic simple oblique duodenoduodenostomy.Ladd procedure was accomplished in 7 cases with congenital intestinal malrotation in the meantime.The average operative time was (115.0±25.5) min (70-145 min). Feedings were started on postoperative 4-10d (mean 6.0d), without abdominal distention and vomit, all patients were discharged in good health with a median postoperative hospital stay of 7-14d(mean 10.6d). There was no mortality rate, no conversion to laparotomy, and no intraopertive complications in the group.The cases were followed-up for 2-36 months (mean 15.6 months), and all cases were doing well.Conclusion:Laparoscopic simple oblique duodenoduodenostomy is safe and efficacious in neonatal period, and can be a viable option in the treatment of neonates with congenital duodenal obstruction.
