Objective To study the clinical manifestations,diagnosis and surgical treatment of tubular adenoma in the extrahepatic bile duct.Methods The clinical data of 3 patients with tubular adenoma in the extrahepatic bile duct who were admitted to the Affiliated Hospital of Inner Mongolia Medical University from July 2010 to February 2012 were retrospectively analyzed.Results The tumors were located at the middle and lower part of the common bile duct.All the 3 patients received resection of the common bile duct and Roux-en-Y cholangioenterostomy,and recovered well.The results of pathological examination showed that all the patients were with tubular adenoma,and 2 patients had moderate atypical hyperplasia.Conclusions Tubular adenoma in the extrahepatic bile duct could be diagnosed by pathological examination.Radical resection and rerouting of the bile duct can get a better outcome.

OBJECTIVETo investigate the clinical effect of penile augmentation with superficial fascia retrocession.

METHODSThe first annular incision line was designed, reserving the inner plate 0.5 -0.8 cm. The second annular incision line was determined, according to the length of penile erection. The skin tissue between the double loops was stripped, reserving the superficial fascia and the superficial dorsal veins. Before the closure of two annual incision with no tension, the superficial fascia tissue was pushed proximally and fixed sectionally to augment penis.

RESULTSFrom Jun 2009 to Jun 2011, 60 patients with redundant prepuce or phimosis were treated with this method. During 3 to 12 months follow-up, the postoperative penile perimeter increased significantly. The glans were exposed and the prepuce looked smooth. The function of the penis maintained undamaged.

CONCLUSIONSThe penile augmentation with superficial fascia retrocession can make full use of autologous tissue to augment penis, meanwhile, redundant prepuce can be resected. It is very practical for clinical application.

Objective To evaluate the therapeutic efficacy and safety of transcatheter closure of atrial septal defect (ASD) and patent ductus arteriosus (PDA) using Amplatzer occluder. Methods Routine cardiac catheterization and angiography were performed in 50 patients (23 male, 27 female, age ranging from 3 to 64 years old), including 19 cases of ASD and 31 cases of PDA under local or general anesthesia. After balloon sizing of the ASD, the optimal Amplazter septal occluder (ASO) was transmitted into the left atrial, and the left and right disks were released in turn. The Amplatzer occluder was completely released after transthoracic echocardiography confirmed that there was no residual shunts or new onset mitral valve regurgitation. The Amplatzer duct occluder (ADO) size was selected according to the narrowest point of PDA measured by angiography, and the occluder was released after the repeated angiography showed no residual shunts. Results ① The mean diameter of the ASD measured by balloon was 13-31 (23?6) mm and the diameter of ASO was (17-40) mm. The immediate closure rate was 100%. ② Angiography confirmed that closure of the ductus using ADO was achieved in 30 patients, and closure of the large size (12 mm) was achieved in 1 case of PDA patient using ASO (17 mm). No complications were encountered. Conclusion Transcatheter closure of ASD and PDA using Amplatzer device, with the advantages of simple operation, confirmative occlusion efficacy, minimal invasiveness, wide indications, and less complications, has a bright future of clinical application.

OBJECTIVETo probe and systematize the ancient cauterization with pyropuncture needle for evacuation of pus.

METHODSOne hundred and eight cases of body surface abscess were randomly divided into 2 groups. The cauterization group (n=84) were treated by drainage with electric cauterization and the incision group (n=24) by drainage with incision. Clinical therapeutic effect, the healing time and the scar area of the wound were compared between the two groups.

RESULTSAll of the patients in the two groups were effective with a similar therapeutic effect (P > 0.05); the cauterization group in the healing time and the scar area of the wound was superior to the incision group (P < 0.05).

CONCLUSIONElectric cauterization for evacuation of pus has advantages of rapid healing and small scar area of wound.

A water-soluble polysaccharide fraction from root of Potentilla anserine was obtained. Gas chromatogram, FT-IR, physical and chemical characteristics of the Potentilla anserine polysaccharide fraction (PAPF) were analyzed. The protective effects of PAPF against the H2O2 induced process of apoptosis of murine splenic lymphocytes were investigated in vitro. Morphological assessment of apoptosis was performed with light microscope and laser scanning confocal microscope. DNA fragmentation was visualized by agarose gel electrophoresis. The amount of apoptotic cells was measured by flow cytometry. The results showed that PAPF is composed of rhamnose, arabinose glucose and galactose. H2O2 (200 micromol x L(-1)) induced apoptosis of murine splenic lymphocytes with the cell volume reduced, cytoplasm and nuclear shrunk and DNA stained non-uniformly. Condensed chromatin and formation of apoptotic body were observed in the apoptotic cells. Apoptotic bodies in the cells treated with PAPF and H2O2 were less than those in H2O2 treatment alone. DNA fragmentation assay showed that PAPF (50, 100, 200, and 400 microg x mL(-1)) obviously reduced H2O2-induced ladder bands. Flow cytometry analysis showed that H2O2 increased the populations of apoptotic sub-G1 cells from 5.60% (control) to 45.40%, and PAPF decreased H2O2-induced apoptosis to 37.80%, 22.70%, 17.70%, and 8.50%, respectively. In conclusion, PAPF reduced H2O2-induced oxidative damage in a dose dependent manner.

OBJECTIVETo examine the effect of hydraulic residence time (HRT) on the performance and stability, to treat dilute wastewater at different operational temperatures in a carrier anaerobic baffled reactor (CABR), and hence to gain a deeper insight into microbial responses to hydraulic shocks on the base of the relationships among macroscopic performance, catabolic intermediate, and microcosmic alternation.

METHODSCOD, VFAs, and microbial activity were detected with constant feed strength (300 mg/L) at different HRTs (9-18 h) and temperatures (10 degrees C-28 degrees C) in a CABR.

RESULTSThe removal efficiencies declined with the decreases of HRTs and temperatures. However, the COD removal load was still higher at short HRT than at long HRT. Devastating reactor performance happened at temperature of 10 degrees C and at HRT of 9 h. HRTs had effect on the VFAs in the reactor slightly both at high and low temperatures, but the reasons differed from each other. Microbial activity was sensitive to indicate changes of environmental and operational parameters in the reactor.

CONCLUSIONThe CABR offers to certain extent an application to treat dilute wastewater under a hydraulic-shock at temperatures from 10 degrees C to 28 degrees C.

Objective: To treat the depressed scars by injecting nanofat and investigate its therapeutic effect. Methods: Autologous fat was harvested from abdomen or thigh using low-pressure suction. The lipoaspirate was mechanically emulsified after rinsing. Emulsification of the fat was achieved by shifting the fat between two 5 ml syringes connected to each other by a three direct connector. After this emulsification process, the fatty liquid was again filtered over the sterile nylon cloth. Nanofat was injected into the dermis of depressed scars using a 26-gauge needle and the injection volume was 1-2 ml/cm². After three months, another injection would be performed if the depressed scar remained obvious. Results: From January 2016 to October 2017, eighteen patients and thirty-three depressed scars were treated. There was a temporary erythema of the injected area that lasted two to three weeks. The clinical result gradually improved over time and were maximal from three months postoperatively for most cases. Three months after nanofat injecting, the cavity of scars was significantly decreased; The color of scars were significantly improved and more close to the adjacent skin; The stiffness of scars was also obvious decreased. The follow-up ranged 4 months to 18 months and the average was 11.0±4.6 months. Seventeen patients were satisfied with the result, one patients was not satisfied and the satisfaction rate was 94%. No infections, fat cysts, granulomas, or other unwanted side effects were observed. Conclusions Nanofat injecting is a definite and effective treatment for depressed scars with fewer complications.

OBJECTIVETo evaluate the effectiveness and safety of the combination chemotherapy of capecitabine (X) with fractionated administration of cisplatin (C) in Chinese patients with advanced gastric cancer (AGC).

METHODS141 patients with AGC were enrolled between July 2002 and August 2004. All patients had measurable tumor according to the criteria of RECIST, Karnofsky performance status > or = 60, adequate bone marrow, renal and hepatic functions. Prior radiotherapy or adjuvant chemotherapy was not permitted. Patients received oral administration of capecitabine at a dose of 1000 mg/m(2) twice a day on D1-D14, and intravenous infusion of fractionated cisplatin at a dose of 20 mg/m(2)/day on D1-D5. The regimen was repeated every 3 weeks, totally for 6 cycles.

RESULTSOf the 141 evaluable patients, there were 104 men and 37 women, with a median age of 54 years (range, 23 - 80 years). Metastases before chemotherapy were detected in lymph nodes (46.8%), liver (40.4%), lung (5.7%) and other area (10.6%). The median treatment duration was 6 cycles (range, 3 - 6 cycles). The objective response rate (RR) was 36.2% (51/141). The median follow-up period was 17.5 months. The median time to progress (TTP) was 9.0 months, and the median overall survival (OS) was 12.0 months. The most common treatment-related adverse events (grade 3/4) were: hand-foot syndrome (HFS) (2.1%), leucopenia (0.7%), abnormal alanine transaminase elevation (2.8%). There was no treatment-related death.

CONCLUSIONCapecitabine combined with fractionated cisplatin is highly effective and well tolerated as a first-line treatment for advanced gastric cancer, with comparable results to 5-Fu plus cisplatin combination therapy.

OBJECTIVETo further explore the effect of annexin I on the tumor growth of human pancreatic cancer in nude mice.

METHODSTo knock down the expression of annexin I in pancreatic carcinoma cells by RNAi. A nude mouse model of human pancreatic cancer was established by subcutaneous inoculation of human pancreatic cancer cell line Suit-II cells. The effect of annexin I on tumor growth was assessed by tumor growth curve and tumor weight records, and Westen blot and flow cytometry were used to examine the expression of annexin I after annexin I-knocking down.

RESULTSThe results of Western blot revealed that the expression of annexin I was significantly decreased in Suit-II cells transfected with pSilencer-annexin I-siRNA1, and almost completely inhibited in the cells transfected with pSilencer-annexin I-siRNA2 and pSilencer-annexin I-siRNA3. The growth of tumors transfected with annexin I-siRNA2 and annexin I-siRNA3 was inhibited by 76.6% and 68.4%, respectively, in comparison with that of tumor from the parent Suit-II cells. At 44 days after tumor cell inoculation, the tumor weight was 0.8987 g (transfected with annexin I-siRNA2) and 0.8992 g (transfected with annexin I-siRNA3), significantly lower (P < 0.001) than that of tumor from parent Suit-II cells (2.5866 g) and transfected with annexin I-siRNAN (2.4070 g).

CONCLUSIONannexin I promotes the growth and proliferation of pancreatic carcinoma cells in vivo and increases the ability of tumor formation in nude mice. The results of this study support that annexin I may become a potential target in gene therapy for this disease.
