Objective To investigate the effects of electroacupuncture (EA) on expression of phosphatase and tensin homology deleted on chromosome ten (PTEN) protein and growth associated protein-43 (GAP-43) in rats with Barrel cortex focal ischemia. Methods 24 adult male Sprague-Dawley rats were divided into sham group (n=8), model group (n=8) and EA group (n=8). The EA group accepted EA at Baihui (DU20) and Fengfu (DU16) acupoints 3 days after modeling, 30 min a time, once a day. They were assessed with Corner Test 1 day before modeling, and 3 days, 7 days and 14 days after medication. The expression of GAP-43 and PTEN around infarct zone were detect with Western blotting 14 days after medication. Results The frequence of turn-right decreased in the EA group compared with that in the model group (P<0.001) 14 days after modeling. The expression of GAP-43 increased in the model group compared with that in the sham group (P<0.05), and increased more in the EA group than in the model group (P<0.05). There was no significantly difference in PTEN expression between the model group and the sham group (P=0.460), and significantly decreased in the EA group (P<0.001). Conclusion EA may inhibit expression of PTEN protein and increase expression of GAP-43, which may be involved in nerve regeneration and functional recovery.

Objective In patients with pulmonary atresia and intact ventricular septum ( PAIVS) without right ventricular-dependent coronaries, catheter techniques including the use of a sniff wire, lasers, and radiofrequency have been the most widely used initial therapy. However, percutaneous perforation and balloon valvuloplasty were associated with higher rate of procedural failure and serious complications. Methods We report our experience with a hybrid approach for pulmonary atresia with intact ventricular septum, combining surgery and interventional catheterization techniques. Between March 2005 and March 2010, hybrid procedure was carried out successfully in 30 newboms and infants with favorable anatomy. The age ranged from 1 day to 48 months with a mean of (4.59 ±3.21) months. The heart was exposed through median sternotomy. A pursestring suture was placed in the right ventricular outflow tract 2 cm away from the pulmonary trunk. Then a 16-gauge intravenous catheter was punctured through the right ventrical and perforated the atretic PV with the guidance of echocardiography. A guide wire was then inserted into the sheath and used to guide the balloon across the PV. Sequential dilations were performed until a full opening of the PV with the guidance of epicardial echocardiography. In patients ＜ 3 months PDA ligation was performed followed by modified Blalock-Taussig (B-T) shunt. In patients ＞ 3 months PDA ligation was not performed. A modified B-T shunt was inserted if severe systemic oxygen desaturation occurred after PDA ligation. Bidirectional Glenn shunt was performed for severe hypoplasia. Hybrid procedure was achieved in all patients. The simultaneous procedures included 25 cases of PDA ligation. 6 newborns underwent modified B-T shunt placement (3.5 to 5 mm) after pulmonary valvuloplasty and PDA ligation, and 2 patients ＞ 1 month underwent modified B-T shunt. Another 2 patients were selected for univentricular palliative surgery because of a diminutive monopartite right ventricle and bidirectional Glenn procedure was performed. No pericardial effusion or cardiac tamponade was observed in all patients. Another case without PDA ligation underwent a modified B-T shunt because of hypoxemia three days after hybrid procedure, and the rest patients were discharged without any further surgical intervention.During the follow-up period of 1.5 to 62.0 months, 5 patients died. 25 (83.3%) survived and were all in New York Heart Association functional class 1. Peripheral oxygen saturation increased from 0.73 ± 0.08 to 0.94 ± 0.04 (P ＜ 0.05). One patient remains in a single-ventricle pathway, whereas 24 patients achieved a two-ventricle circulation. Results Conclusion Perventricular balloon pulmonary valvuloplasty using a hybrid approach is a safe and feasible procedure for patients with PAIVS.

Objective To study the expression of chemokine receptor 5 (CCR5) in breast cancer and metastatic axillary nodes and the frequency of polymorphism CCR5-△32,and its effect on breast cancer metastasis.Methods Specimens were collected from Aug.2008 to Jun.2009 in Department of Breast and Thyroid Surgery,Liaocheng People's Hospital.The relative expression quantity of CCR5 mRNA was detected by real-time fluorescence quantitative PCR (RT-PCR),and polymorphism CCR5-△32 was tested by DNA electrophoresis.The data was processed by SPSS software.Results 1.The relative expression quantity of CCR5 mRNA was significantly higher in breast cancer tissues than in paracarcinoma tissues(P ＜ 0.01)and breast fibroadenoma tissues (P ＜ 0.05).The difference of relative expression quantity of CCR5 mRNA had statistical significance between breast cancer tissues in stage Ⅱ and Ⅲ(P ＜ 0.05 ),but not between breast fibroadenoma tissues and paracarcinoma tissues(P ＞0.05).2.The relative expression quantity of CCR5 mRNA was significantly higher in metastatic axillary nodes than in nonmetastatic nodes (P ＜ 0.05 ).3.Polymorphism CCR5-△32 wasn't found in any specimen.4.The relative expression of CCR5 mRNA had connection with breast oncogene C-erbB-2 and whether there was axillary lymph node metastasis,but no connection with other immunological and biochemical indicators.Conclusions CCR5 mRNA is significantly higher expressed in breast cancer and metastatic axillary nodes.The interaction between CCR5 and its ligands promotes the progress of breast cancer and axillary lymph node metastasis.CCR5 can be taken as a molecular indicator to predict axillary lymph node metastasis in breast cancer and provides new targert for clinical therapy.

Objective: To investigate the prevalence and influencing factors of hyperuricemia among adults in Xinjiang Uygur Autonomous Region, so as to provide insights into the prevention and intervention of hyperuricemia. Methods: Permanent residents at ages of 18 years and above in 8 counties (cities, districts) of Xinjiang Uygur Autonomous Region were sampled using a multi-stage cluster random sampling method from July 2018 to November. Demographic data, smoking, alcohol consumption, body mass index and serum uric acid were collected through questionnaire surveys, physical examination and laboratory testing. Factors affecting hyperuricemia were analyzed using a multivariable logistic regression model. Results: A total of 4 690 residents were collected, including 2 093 males (44.63%) and 2 597 females (55.37%), and had a mean age of (49.45±14.57) years. There were 1 795 overweight residents (38.27%), 1 198 residents with obesity (25.54%), 983 smokers (20.96%), 1 224 drinkers (26.10%), and 268 residents with hyperuricemia (5.71%). Multivariable logistic regression analysis showed that a higher risk of hyperuricemia was seen among adults who were males (OR=1.409, 95%CI: 1.036-1.917), aged 60 years and above (OR=2.092, 95%CI: 1.495-2.928), had high school education or above (high school, OR=2.003, 95%CI: 1.366-2.937; college and above, OR=4.876, 95%CI: 3.196-7.438), were overweight (OR=2.343, 95%CI: 1.618-3.395) or obese (OR=4.754, 95%CI: 3.291-6.868) and had alcohol consumption (OR=1.494, 95%CI: 1.104-2.020). Conclusion The risk of hyperuricemia may be associated to gender, age, educational level, body mass index and alcohol consumption among adults in Xinjiang Uygur Autonomous Region.

ObjectiveTo investigate the clinical features of clonorchiasis diagnosed during biliary surgery, and to provide more comprehensive and effective information for the surgical treatment of clonorchiasis. MethodsA retrospective analysis was performed for the clinical data of 15 patients who were diagnosed with clonorchiasis during and after biliary tract surgery in our department from January 2013 to January 2016, and their clinical features were summarized. ResultsAll the 15 patients were male, among whom 5 once ate uncooked freshwater fish and shrimps. Of all patients, 8 underwent laparoscopic bile duct exploration and 7 underwent endoscopic retrograde cholangiopancreatography (ERCP). Adult Clonorchis sinensis was found in intraoperative or postoperative drainage. All the patients achieved clearance of Clonorchis sinensis after regular anthelmintic treatment. ConclusionIf bile duct exploration finds grey-black or bright-red melon seed-like floccules, clonorchiasis should be highly suspected. Intraoperative T-tube drainage is recommended, and if suspected Clonorchis sinensis is found after laparoscopic bile duct exploration and T-tube drainage or after ERCP and nasobiliary drainage, microbiological examination should be performed next. As for the patients with a definite diagnosis of clonorchiasis, they should not eat uncooked freshwater fish or shrimps and should be given regular anthelmintic treatment.

Objective To explore rationale and clinical application of simplified modified radical thyroideetomy for differentiated thyroid carcinoma.Methods From Jan.2007 to Jun.2010,349 cases of differentiated thyroid carcinoma received simplified operative procedure based on standard modified radical thyroidectomy.The simplified procedure took a low small collar incision(about 10-12 cm).In separating upper and lower skin flaps,subcutaneous tissues covering posterior triangle of neck and posterior edge of sternoeleidomastoid muscle were spared to protect sensory nerves.Subtotal thyroidectomy Was performed to resect the affected lobe,isthmus,and the majority of opposite lobe without considering the size of primary tumor or whether metastasis to the neck lymph nodes happened.Soft tissues of the mainly metastatic areas(Ⅱ a、Ⅲ、Ⅳ、Ⅴb)were cleared.The accessory nerve was not exposed routinely to avoid stimulation.Lymph nodes metastasis in different areas was recorded respectively.Complications in different operative modes were compared.Results Compared with standard modified radical thyroidectomy,the simplified mode had shorter scar-and no limit of neck mobility.Because of muscles and nerves pemervation,movement dysfunction and abnormal sensation of neck and shoulder decreased obviously.The operation duration was shortened.Cervical lymph node status Was evaluated,which provided basis for prognosis judgment and comprehensive treatment.Conclusions The simplified modified radical procedure has the benefit of decreased trauma while maintains the similar recurrence rate compared to modified radical thyroidectomy.It improvs the life quality of patients.This procedure fits the principle of functional radical neck dissection better.

OBJECTIVETo evaluate the potential role of BME-10X collagen/hydroxyapatite (HA) bone graft in periodontal tissue regeneration.

METHODSFour 18 months old male beagles in the experiment were treated with non-surgical periodontal therapy. At the sites of mandibular 3rd and 4th premolars at the time of dogs were treated with non-surgical periodontal therapy one week later, the teeth with the same name in the same jaw were selected to the experimental group (T group) or the control group (C group) at random. The defects in T group were filled with BME-10X collagen/HA bone graft while the defects in C group were filled with nothing. The dogs were sacrificed in twelve weeks and analyzed by histopathology.

RESULTSThe defects in T group got more tissue regeneration compared with the defects in C group. The height of new bone (NB) was (3.01 +/- 0.14) mm in T group versus (1.32 +/- 0.11) mm in C group (P < 0.05). The height of new periodontal ligament (NP) was (3.12 +/- 0.19) mm in T group versus (1.35 +/- 0.12) mm in C group (P < 0.05). The height of new cementum (NC) was (3.30 +/- 0.15) mm in T group versus (2.70 +/- 0.12) mm in C group (P > 0.05). The new tissue guided by the bone graft was the same as the normal tissue in histopathology analysis.

CONCLUSIONThe results of the study suggest that BME-10X collagen/HA bone graft is a good bone graft for periodontal tissue regeneration.
