Objective To explore the impact of juxtapapilary duodenal diverticulum on the formation of choledocholithiasis and biliary manometry after surgery.Methods The clinical data of 97 patients with common bile duct stones who successfully underwent ERCP and biliary manometry treatment from May 2011 to March 2014 were retrospectively analyzed.Ninty-seven common bile duct stone patients were divided to two groups,that is,52 cases of juxta-papilary duodenal diverticulum (experimental group) and 45 cases without juxta-papilary duodenal diverticulum (control group).The biliary manometric results before and after EST of both groups were compared.Results The basal pressure of sphincter Oddi of the experimental group before EST [(84.8 ± 26.1) mmHg] was higher than that of the control group before EST [(75.5 ± 14.6) mmHg] (P ＜ 0.05,1 mmHg =0.133 kPa);and that after EST was also higher than that of the control group after the operation[(19.8 ± 14.2)mmHg VS (15.9 ± 9.8)mmHg,P ＜ 0.05].The biliary pressure of common bile duct stone patients with JPD was higher than those without JPD before and after EST but with no significant difference(P ＞ 0.05).The biliary manometry was performed in 81 patients after one month and it was found that the basal pressure of sphincter Oddi of experimental group was still higher than that of the control group [(34.8 ± 17.1) mmHg VS (29.6 ± 15.3)mmHg,P ＜ 0.05].The biliary pressure of common bile of the experimental group was higher than that of the control group [(19.9 ± 11.2) mmHg VS (17.1 ± 13.1)mmHg,P ＜0.05].Conclusion The existence of juxtapapilary duodenal diverticulum increases the pressure of common bile duct and Oddi sphincter and leads to CBD stones.

OBJECTIVE To investigate the pathogenic causes of community-acquired pneumonia(CAP) in adult patients in Tongling.METHODS A prospective study was performed on 260 consecutive adult patients with CAP in Tongling city during last three years.Bacteria culture of sputum and serological tests in paired serum samples were detected.RESULTS Of 260 patients with etiological evaluation,128(49.2%) patients had an identifiable etiology,63(24.2%) had positive outcome from sputum cultured,atypical pathogens were detected from 75(28.8%)patients.Pathogens identified in 128 patients were:Mycoplasma pneumoniae(35.4%),Chlamydia pneumoniae(17.7%) and Streptococcus pneumoniae(13.6%).6.5% All patients had mixed infection.The resistance rate of S.pneumoniae to penicillin and erythromycin was 5 and 50%,respectively.CONCLUSIONS Atypical pathogens have important role in CAP,of which M.pneumoniae is the most common pathogen.S.pneumoniae and K.pneumoniae are the commonly encountered bacteria for CAP in Tongling.

Objective To explore the clinical features and operative method of complicated spinal tuberculosis. Methods Totally 562 inpatients suffering from spinal tuberculosis during January 1997 to December 2006 were reviewed retrospectively. A new definition of complicated spinal tuberculosis was made. Complicated spinal tuberculosis was classified into different types. Every type had its special surgical operation approach. Results Among the 87 cases being followed up for 45 months, 75 patients were totally recovered, and 12 patients were obvious improved on the mend according to Dr. Fang Xian-zhi’s standard. The classification of function which above good was 97.1%. The fusion rate was 96.3% during 87 patients who received bone grafting treatment 9 months ago. Posterior convex angle was 24? to 57?, average 35.3?. Conclusion We consider that complicated spinal tuberculosis will not be surgical contraindication. Different types of complicated spinal tuberculosis by different operation approach, and careful preparation before operation will gain good curative outcome.

Objective To explore the clinical value of laparoscopic hepatectomy for the treatment of hepatic hemangioma.Methods Clinical data of forty-six patients treated with hepatic hemangioma hepatectomy in Dongfeng Hospital Affiliated to Hubei University of Medicine from February 2014 to February 2017 were collected.The patients were divided into the laparoscopic hepatectomy group (LH group 26 cases) and the open hepatectomy (OH group 20 cases) by retrospective descriptive study.The operation time,hepatectomy time,intraoperative blood loss,postoperative complications,postoperative liver function recovery time,hospitalization time,total hospitalization cost,number of residual tumor tissues and follow-up recurrence rate of the two groups were compared.Results The length of incision in the laparoscopic hepatectomy group was significantly lower than that in the open hepatectomy group ((5.41±0.53) cm vs.(19.72±1.26) cm,t=52.335,P=0.000),the intraoperative blood loss,operation time,exhaust time,indwelling drainage time,first postoperative feeding time and postoperative hospitalization time in the LH group were significantly lower than those in the OH group ((572.23±16.92) ml vs.(911.75±19.41) ml,(149.52±18.14) min vs.(171.47±21.35) min,(2.84±0.63) d vs.(3.46±0.57) d,(5.74±3.380) d vs.(10.62±3.59) d,(2.08±0.52) d vs.(3.10±0.61) d,(8.91±2.16) d vs.(14.84±2.09) d,t=63.287,3.767,3.447,4.725,6.117,9.360,P<0.05);in the LH group,liver function recovery index alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were significantly lower than those in the OH group ((45.73±2.16) U / L) vs.(149.29±3.44) U/L,(47.32±1.89) U/L vs.(50.60±3.53) U / L,t=124.985,4.051,P<0.05).Conclusion Laparoscopic hepatectomy for patients with hepatic hemangioma is characterized by less trauma,quicker recovery and higher safety.

AIM:We generated transgenic mice of NKCC1-/-(homozygous mutant),NKCC1+/-(heterozygous)and NKCC1+/+(wild-type)that have a targeted disruption in the NKCC1 gene to investigate the role of Na-K-2Cl(NKCC1)channel in auditory function of the inner ear.METHODS:Hearing threshold and endocochlear potential(EP)were measured in the NKCC1-/-,NKCC1+/-and NKCC1+/+ mice by auditory brainstem response(ABR)and EP recordings,respectively.The inner ears of the mice were removed and examined morphologically with the light microscope.RESULTS:The auditory function of NKCC1+/+ mice was normal,the mean value for ABR thresholds in response to click sound was [(23.13?3.78)dB,SPL],EP was(98?16)mV.The mean value for ABR thresholds to click sound was elevated in NKCC1+/-mice [(38.49?12.29)dB,SPL],relative to that significantly increased in NKCC1+/+ mice(P

Aim To investigate the effects of suppressor of cytokine signaling-1(SOCS-1)on advanced glycation end products(AGEs)induced-renal tubular epithelial-myofibroblast transdifferentiation and activation of JAK/STAT in cultured human renal tubular epithelial cells(HKC).Methods Stable transfections of HKC with pCR3.1 vector and pCR3.1/SOCS-1 were performed with Lipofectamine 2000,and cells were selected with geneticin.Cells were stimulated with BSA and AGEs. The protein expressions of SOCS-1,α-SMA,E-cadherin,Col I,signal transducer and activatior of transcription 1,3(STAT1,STAT3),p-STAT1 and p-STAT3 were observed by Western blot.The protein synthesis of TGF-β_1 in the supernatants of the HKC was detected by enzyme-linked immunoadsorbent assay(ELISA).α-SMA and E-cadherin mRNA were measured by reverse transcription and polymerase chain reaction(RT-PCR).Results Compared with control group,the expression levels of α-SMA protein and mRNA and Col I were significantly increased in HKC with AGEs stimulation and there was a higher concentrations of TGF-β_1 in the supernatants.However,the expression of E-cadherin protein and mRNA were decreased with AGEs stimulation.Overexpression of SOCS-1 inhibited AGEs-induced activation of STAT1 and STAT3 and high expression of α-SMA protein and mRNA and Col I,and reversed the expression of E-cadherin protein and mRNA induced by AGEs.Meanwhile,overexpression of SOCS-1 reduced the concentration of TGF-β_1 in the supernatants of HKC with AGEs stimulation.Conclusion Overexpression of SOCS-1 inhibits AGEs-induced renal tubular epithelial-myofibroblast transdifferentiation maybe partly through blocking activation of JAK/STAT.

To investigate whether the change of E-cadherin (ECD) expression plays a role in the injury and repair of airway epithelial cells (AEC) caused by smoking, porcine AECs were cultured by using an enzyme-dispersed method. After exposure of the AECs to cigarette smoke extract(CSE), the ECD expression in the cells was detected by using immunocytochemistry and in situ hybridization. The results showed that ECD was distributed on the plasma membrane at the cell junctions of AECs. After exposure to 20% CSE, the membranous ECD expression was decreased, the cytoplasmic ECD expression was increased (P＜0.01) as the exposure time went on.But the content of ECD mRNA in the AECs did not chang. It suggests that the change of ECD expression is regulated at the posttranslational level and plays a role in the injury and repair of AEC caused by smoking.
