ObjectiveTo investigate the diagnostic and prognostic significance of serum human kallikrein11 ( KLK11 ) in patients with ovarian cancer. MethodsThe level of serum KLK11 was determined by enzyme-linked immunoassay(ELISA) for 30 patients with ovarian cancer, 26 patients with benign gynecologic processes and 32 healthy subjects,and the KLK11 value beyond the upper-limit of 95％ credibility interval( 95％ CI) based on the health controls was used as the positive value. The positive rate of KLK11 was compared among the three groups.ResultsThe positive rate of KLK11 in patients with ovarian cancer was significantly higher than those in patients with benign gynecologic processes or in healthy subjects[(73.3％) and(7.7％ ) or(6.3％ ) ,all P ＜0.01 )] ,and there was no significant difference between ovarian benign tumor group and the healthy control group ( P ＞ 0.05 ).ConclusionThe serum KLK11 should be a novel tumor marker in the clinical diagnosis of ovarian cancer.

Objective To observe the effect of electroacupuncture(EA) on the expression of glucose transporter-1(GLUT-1) of hippocampal microvascular endothelial cells in focal cerebral ischemia(CI) rats.Methods Sixty male Wistar rats were randomly divided into sham-operation,model and electroacupuncture(EA) groups.CI model was established by middle cerebral artery occlusion with a piece of thread embolus.EA(4 Hz/20 Hz,1 mA) was applied to bilateral "Neiguan"(PC 6) for 30 min,once daily for 15 days.GLUT-1 expression in the hippocampus was detected with immunohistochemistry and Western blot,respectively.Results After the treatment,compared with the sham-operation group,the expression of GLUT-1 in microvascular endothelial cells of the hippocampus in model group shown by both histochemical and Western blot techniques decreased apparently(P

Clopidogrel is an essential drug for the treatment of ischemic stroke.It has been recommended by the multinational stroke treatment guidelines and has been widely used in clinical practice.Many patients with ischemic stroke may still have stroke recurrence after the standard treatment of clopidogrel; therefore,we must pay attention to the phenomenon of clopidogrel resistance.This article reviews the biochemical mechanisms,gene polymorphism,laboratory testing,and response measures of clopidogrel resistance.

Objective To discuss adhesion blocking experiment of vascular endotelial cells with platelets.Methods The expression,regulation and adhesion of CD226 on vascular endothelial cells incubated by sera from 10 PIH patients and 10 normal pregnant women repectively was detected by flow cytometry,then incubated with interacted platelets by PTA1/Ig protein.Results The positive rate of CD226 in PIH group was significantly higher than that in normal pregnant woman group(P

Aim To investigate the effect of chronic intermittent hypobaric hypoxia ( CIHH) on the paeonol induced vasomotion of isolated rat ’ s thoracic aorta rings and its underlying mechanisms. Methods Spra-gue-Dawlay ( SD ) rats were randomly divided into 2 groups: control group ( CON ) and CIHH treatment group ( CIHH) . CIHH rats were exposed to hypoxia in a hypobaric chamber simulating 5 000 m altitude, 6 hours daily for 28 days. CON rats lived in the same en-vironment as CIHH animals except hypoxia. Organ bath technique was used to observe the effect of pae-onol on isolated thoracic aorta rings of rats. Results There were no significant differences of noradrenaline ( NE )- and KCl-induced contraction in thoracic aorta rings among CIHH and CON rats;CIHH enhanced va-sodilative effects of paeonol on isolated thoracic aorta rings of rats; the vasodilative effects on CIHH rats could be partly decreased by β-receptor blocker prop-ranolol,ATP-sensitive potassium channel ( KATP ) bloc-ker glibenclamide and NO synthase inhibitor L-NAME. Paeonol significantly inhibited NE-induced intracellular and extracellular calcium-dependent contraction in CIHH rats. Paeonol didn ’ t inhibit NE-induced con-traction by intracellular calcium release and its inhibi-tory effect couldn ’ t be blocked by glibenclamide in CON. Vasodilative effects of paeonol couldn ’ t be re-versed by indomethacin, a cyclooxygenase inhibitor, in CIHH and CON rats. Conclusion CIHH significantly enhances vasodilative effects of paeonol on isolated tho-racic aorta rings of rats. Besides promoting the signa-ling pathway of paeonol in CON, CIHH significantly enhances vasodilative effects of paeonol via activating KATP and inhibiting Ca2+ release from sarcoplasmic re-ticulum.

Objective To evaluate the incidence and significance of perineural invasion (PNI) in cervical cancer. Methods Retrospective chart review of patients with cervical cancer (stages Ⅰa2-Ⅱb) who underwent radical hysterectomy and pelvic lymphadenectomy from 2007 to 2012. To evaluate the incidence and significance of PNI in cervical and uterine tissues by microscopic examination. Results A total of 238 patients were included, 9.2% (22/238) patients with PNI in the cervical stroma. Patients with PNI were more likely to have adverse histopathologic features, including lymphoma vascular space invasion, parametrical invasion, depth of invasion, tomor size and lymph nodes metastases (all P<0.05). PNI were independent of age, international federation of gynecology and obstetrics (FIGO) stage, histopathology type and grade, and positive vaginal margin (all P>0.05). Patients with PNI had shorter disease-free and overall survival (P=0.002 and P=0.008, respectively). On multivariate analysis, risk factors for recurrence and death included parametrical invasion and depth of invasion (P<0.05). Similarly, risk factors for recurrence included lymph nodes metastases (P=0.024). However, PNI was not identified as an independent risk factor for either recurrence or death (P>0.05). Conclusions PNI exists in early cervical cancer. PNI is associated with tumor size, depth of invasion, parametrical invasion, lymphoma vascular space invasion and lymph nodes metastases. PNI represente a decreasing disease-free and overall survival in patients with early-stage cervical cancer, and is independently associated with multiple high-risk factors, which be informed management decisions regarding adjuvant therapy.

To optimize the water extraction process for glycyrrhiza. Methods: HPLC was used to determine the con-tents of glycyrrhizic acid and liquiritin. The comprehensive index included the contents of glycyrrhizic acid and liquiritin and the yield of dry extract. The water amount and the extraction time were selected as the independent variables, and the comprehensive index was set as the dependent variable. Design-expert 8. 06 software was used to fit multivariate linear or quadratic multinomial models for the experimental values. Response surface methodology was used to optimize the water extraction process. The prediction was carried out through comparing the observed and predicted values. Results:The regression coefficient of binomial fitting complex model was as high as 0. 979 7. The optimum conditions of extraction process were as follows:12-fold amount of water, extracting 3 times with 90 min for each time. The deviation between the observed and predicted values was -1. 72%. Conclusion: Central composite design-response surface methodology is convenient and highly predictive in optimizing the water extraction process for glycyrrhiza, which can be applied in the further membrane separation and purification.

Objective To investigate the effectiveness of intermittent pneumatic compression (IPC) devices combined with anticoagulants for the prevention of deep vein thrombosis (DVT) after joint replacement surgery.Methods All of 400 patients were involved in this prospective randomized control study with 100 total knee arthroplasty (TKA) patients and 100 total hip arthroplasty (THA) patients in each group.All patients were operated under the general anesthesia.Patients in the control group received 10 mg of rivaroxaban per day beginning 6-8 hours after the surgery.Besides the prescription of rivaroxaban, IPC devices were used just after the anesthesia in the operating theater and lasted for 48 hours in the experimental group.The diagnosis of DVT in the lower extremities was made by color Duplex sonography on the second postoperative day.The incidence rate of DVT and symptomatic pulmonary embolism was recorded.The incidence rates of total DVT, proximal DVT (p-DVT, proximal to the trifurcation of the popliteal vein), distal DVT (d-DVT, in the anterior tibial vein, posterior tibial vein or peroneal vein) and intermuscular DVT were recorded.CT pulmonary angiography was used to confirm the pulmonary embolism if it was suspected.Results The incidence rates of overall, proximal, distal and intermuscular DVT were 9.5％, 0.5％, 0.5％, 8.5％ in the experimental group and 30％, 0.5％, 5.5％, 24％ in the control group respectively.The incidence rates of total DVT, distal DVT and intermuscular DVT were significantly lower in the experimental group.The incidence rate of DVT in TKA patients and THA patients were significantly lower in the experimental group than in the control group respectively.For patients with DVT, enoxaparin was used instead of rivaroxaban, and DVT was found disappeared by color Duplex sonography 10-12 days postoperatively.Conclusion Compared with the use of rivaroxaban alone, IPC devices combined with anticoagulants can significantly reduce the incidence rate of distal DVT and intermuscular DVT in the early postoperative period after joint replacement surgery.

BACKGROUND:Some studies have focused on bone marrow mesenchymalstem cells (BMSCs) combined with allograft bone or artificial bone substitute materials for bonedefect repair. But there is no report on BMSCs combined with Bio-oss for repair of rabbit skull defects as yet.OBJECTIVE:To observe the effect ofBMSCs combined with Bio-oss in repairing skull defects in rabbits.METHODS:BMSCs from male rabbits were isolated, cultured, and used as seed cells. In the skull of the female rabbits,three full-thickness bone defects with the same external diameter of 6 mm were made by a ring bone drill. Ninety-six female rabbits were randomly divided into four groups, and given Bio-oss/BMSCs in combination group, Bio-oss alone in Bio-oss group, BMSCs implantation in BMSCs group, and no intervention in blank group. All the implant surfaces were covered with guided tissue regeneration membrane.RESULTS AND CONCLUSION:The osteogenic effect in the combination group was better than that in the other three groups, and the Bio-oss group showed better osteogenesis in comparison with BMSCs and blank groups. But there was no significant difference between the BMSCs and blank groups. These findings indicate that the combined use of BMSCs as seed cells and Bio-oss as a scaffold material exerts overt osteogenic effects in rabbit skull defect area, which provides a new idea for the clinical treatment of bone defects.

Objective To investigate the clinical effect of the V-Y advancement flap based on double perfo-rators of the posterior tibial artery for reconstruction of small-area tissue defect in the achilles tendon. Methods From June, 2014 to June, 2017, a total of 8 patients with small-area tissue defect in the achilles tendon were repaired by the V-Y advancement flap based on double perforators of the posterior tibial artery. The size of defects ranged from 1.5 cm ×3.5 cm to 3.5 cm ×5.0 cm, and the size of flaps ranged from 2.0 cm ×8.0 cm to 4.0 cm ×12.0 cm. The donor area was directly sutured. Eight cases were followed-up, and the appearance, quality, color and elasticity was raorded. Results All V-Y advancement flaps based on double perforators of the posterior tibial artery survived, and all donor sites were directly sutured. Followed-up for 3 to 12 months. All V-Y advancement flaps were flat with the sur-rounding tissue. The appearance, quality, color and elasticity of flaps were good. According to the related evaluation criteria made by the American Orthopedic Foot and Ankle Surgery Society (AOFAS), the results of 8 patients were ex-cellent in 6 cases, and good in 2 cases. The patients had a high degree of satisfaction. Conclusion Application of the V-Y advancement flap based on the double perforators of the posterior tibial artery is an ideal method to repair the small-area tissue defect in the achilles tendon. This kind of surgery is simple, safe and has minimal donor site mor-bidity.
