Objective To study the expression of KAI1 and CD40 in gastric cancer and their correlation with clinicopathologic features and prognosis.Methods The expression of KAI1 and CD40 of 64 gastric cancer tissues was examinated by S-P immunohistochemieal methods.Results The overall positive rate of KAI1 was 22% in gastric cancer.Expression of KAI1 was positively related to the degree of tumor differentiation,it was negatively related to invasion depth and lymph node metastasis and the tumor clinical stage.The 5-year survival rate of cases with positive expression of KAII was significantly higher than that of cases with negative expression(X~2=42.426,P=0.000).The expression rate of CD40 in gastric cancer tissue was 34%.The expression of CD40 was significantly correlated with metastasis and clinical stage of gastric cancer.The 5-year survival rate of cases with positive expression of CD40 was significantly lower than that of cases with negative expression(X~2=4.841,P=0.028).There is no relationship between KAI1 and CD40 expression in gastric cancer.Conclusion KAI1 is associated with gastric cancer differentiation,invasion and metastasis.CD40 status helps to evaluate metastasis,and predict prognosis of gastric cancer.

An HPLC method for the determination of 18alpha-glycyrrhetinic acid and 18beta-glycyrrhetinic acid in rat plasma was established, which was used subsequently to determine the pharmacokinetic profiles of both epimers of glycyrrhetinic acid in rats. alpha-glycyrrhetinic acid, beta-glycyrrhetinic acid, and a mixture of alpha-glycyrrhetinic and beta-glycyrrhetinic acids were administered to rats via gastric infusion. Blood samples were collected at different time intervals and extracted by liquid-liquid extraction. Separation was achieved by using a Kromasil C18 column (150 mm x 4.6 mm, 5 microm) with the mobile phase composed of acetonitrile--4 mmol x L(-1) ammonium acetate solution (46 : 54, v/v) at a flow rate of 1.0 mL x min(-1), and the detection wavelength was set at 250 nm. The pharmacokinetic parameters were calculated using the software DAS 2.0. In a combined administration, the main pharmacokinetic parameters of beta-glycyrrhetinic acid are significantly different from that of alpha-glycyrrhetinic acid (P < 0.05), while no significant difference was obtained when administrated individually. Compared to the single administration, significant differences (P < 0.05) on the values of AUC(0-t) and AUC(0-infinity) of beta-glycyrrhetinic acid were observed when this chemical was administrated together with alpha-glycyrrhetinic acid. In contrast, the pharmacokinetic parameters of alpha-glycyrrhetinic acid were not affected even under the co-administration. Here, a sensitive, specific, rapid and reproducible HPLC method was developed for the pharmacokinetic studies of alpha-glycyrrhetinic acid and beta-glycyrrhetinic acid in rat plasma.

AIM: To estimate the pooled prevalence of myopia among primary school students in mainland China during 1980- 2013. Myopia had become a growing public health issue, with high prevalence rates in mainland China, particularly among children. However, we still had no population-based nationwide studies of the prevalence of myopia among primary school students in recent years. METHODS: Wanfang, Chinese National Knowledge Infrastructure and PubMed databases were searched independently until Dec. 31, 2013 to identify relevant articles. Data from the eligible articles were extracted by two reviewers. All of the data analyses were conducted using Meta-Analyst software (version 3. 13, USA).
RESULTS: Thirty - seven eligible studies published between 1980 and 2013 were selected with a total of 245248 individuals. The pooled prevalence of myopia among the included individuals was 26. 5% (95% CI: 21. 8% -31. 7%). The prevalence of myopia increased with age (from 8. 4%at 6-8y to 57. 4% at 12-14y).
CONCLUSION: The pooled prevalence of myopia among primary school students in mainland China was much higher than that of western countries or regions. The prevalence of myopia increased with age among primary school students. This study should be valuable for myopia prevention and treatment in mainland China.

OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.

METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.

RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.

CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.

Objective To investigate the effect of local injection of Botulinum toxin type A(BTXA) on spasticity and function of the affected upper limb in stroke patients.Methods A total of 32 stroke patients were re- cruited and randomly divided into two groups:a BTXA group and a control group.All the patients had spasticity of upper limb muscles,which scored grade 2 to 3 with the Modified Ashworth Scale(MAS) ,and decreased elbow joint range of motion.The 16 patients in the BTXA group received BTXA injection in the biceps brachii muscles and flexor muscles of forearm on 10～15 points,while those in the control group did not.All the patients in both groups were treated with rehabilitation training techniques.The MAS,Fugl-Meyer upper limb function assessment and Barthel In- dex were employed to evaluate the changes of muscle tone,upper limb function and activity of living (ADL)perform- ance of the patients before injection and at 1st,2nd,6th 12th weeks after injection.Results The therapeutic effect between the BTXA group anti control group was significantly different in terms of biceps muscle tone,the scores of Fugl-Meyer upper limb function assessment and Barthel Index.Compared with preinjection,muscle tone was de- creased significantly and ADL performance was improved after injection in BTXA group.The effects of BTXA lasted more than 12 weeks.Conclusion Intramuscular muhipoint injection of BTXA was useful in reducing muscle spas- ticity,and was helpful for increasing motor ability of the affected upper limb and ADL performance of the stroke pa- tients.

AIM: To investigate the ocular complication after radiation therapy for nasopharyngeal carcinoma(NPC).METHODS: The authors performed a previous study on keratopathy in 213 NPC patients who received first stage radiation and had at least 10 months of follow-up. These patients were categorized into three groups depending on NPC clinic stages. Rates and proportions of keratopathy occurring in these groups were compared and analyzed with Chi-square Test and Spearman rank correlation coefficient.RESULTS: Radiation keratopathy developed in 19 patients, about 8.9% (19/213). The latency value was 3 to 30days. The effect of NPC clinic stages and radiation did on the development of keratopathy was not statistically significant (P＞0.05).CONCLUSION: The NPC clinic stages and radiation doses plays few effects on the development of keratopathy. It may play a key role that corneal nerves damage induced ocular surface diseases. It can not be excluded that individuals have different sensitivities to radiation.

Objective To compare the clinical outcomes of in vitro fertilization-embryo transfer(IVF-ET) in polycystic ovary syndrome(PCOS) patients with different body mass index(BMI).MethodsEighty-seven PCOS patients who received IVF-ET were classified into four groups according to BMI: group A,BMI0.05).ConclusionThe doses of gonadotropins are increased in PCOS patients with increasing BMI.The number of usable embryo is significant decreased in PCOS patients with BMI≥25 kg/m2.
