Objective To observe the effects of lower limb motion control training using virtual games combined with core stability training (CST) on the lower limb motor function of hemiplegic patients after stroke.Methods Sixty hemiplegic stroke patients were divided into an observation group and a control group (n =30 in each) using a random number table.The control group was given conventional treatment and CST,while the observation group received lower limb motion control training using virtual games in addition to conventional treatment and CST.All of the patients were assessed using the Fugl-Meyer lower limb assessment (FMA),the Berg balance scale (BBS),the modified Barthel index (MBI),10 metre maximum walking speed (MWS) and functional ambulation categorization (FAC)before and after 8 weeks of treatment.Results Before the intervention there was no significant difference between the two groups in any of the measurements.After the treatment,however,the average FMA,BBS,MBI,MWS and FAC in the observation group were significantly better than those before treatment and those in the control group.Conclusions Lower limb motion control training using virtual games combined with core stability training can improve effectively the lower limb motor function of hemiplegic patients after stroke.Such a combination is worth applying in clinical practice.

The fasting blood sugar (FBS), blood insulin (INS), insulin sensitivity index (ISI) and resistant hormone of INS in 46 patients with NIDDM were observed before and after the treatment. It was showed that the good effect was achieved in the cases by acupuncture and moxibustion, while the contents of FBS and INS in plasma were all decreased and ISI was increased in the cases treated by acupuncture and moxibustion, the degree of decrease of FBS and INS, and increase of ISI being closely related to therapeutic effect. The level of resistant hormone of INS and lipid in patients tend to normal level. Acupuncture and moxibustion had a good regulatory effect on the function of endocrine,sugar and lipid metabolism. It suggests that IR can be corrected by acupuncture and moxibustion,which is a key to therapeutic effect.

Objective To provide references for enriching and innovating patterns of TCM syndrome differentiation by exploring the relationship between pathological changes and TCM syndrome differentiation of delayed graft function (DGF) after renal transplantation. Methods Totally 57 patients with DGF after renal transplantation who were diagnosed by pathological biopsy were also diagnosed by TCM doctors to obtain TCM syndromes. And the pathological diagnoses were compared with the distribution of TCM syndromes to discuss the relationship between them. Results All the patients were classified into four TCM syndromes:spleen-kidney qi deficiency, liver-kidney yin deficiency, qi-stagnation and blood stasis, and deficiency of both qi and yin. The results of pathological biopsy were as follows:acute tubular necrosis, calcineurin inhibitor toxicity and acute rejection. Quantitative corresponding relation was found between the pathological diagnoses and the TCM syndromes. Conclusion There are inner links between pathological diagnosis and TCM syndromes of DGF, which can be references for diagnosis and treatment of TCM syndrome differentiation.

Objective To observe the effectiveness of early enteral nutrition (EEN) in managing ICU mechanically ventilated patients.Methods Totally 47 patients who had been ventilated for more than one week were randomly divided into EEN group and control group.The EEN group was supplied with enteral nutrition (EN) 12-24 hours after ICU admission,whereas the control group received EN 72 hours-5 days later.The function of intestinal mucosal barrier was evaluated by the reabsorb concentration of disaccharides lactulose/mannitol (L/M).In addition,the body mass index (BMI),body temperature,urine L/M ratio,serum albumin,pre-albumin,and ventilation days were recorded or calculated.Results On the seventh day,the L/M ratio was (0.036 ±0.004) in the EEN group,which was significantly lower than that (0.108 ±0.020) in the control group (t =2.746,P ＜0.01) ; the average body temperature was significantly lower in the EEN group than in the control group [(38.25 ± 1.20) ℃ vs (38.92 ± 1.40) ℃ ; t =2.683,P ＜ 0.05)] ; the incidences of adverse reactions such as constipation and diarrhea were significantly lower in the EEN group [16.7％ (4/23) vs 27.3％ (6/22),P＜0.05].The weaning rate within 2 weeks also favoured the EEN group [90％ (18/20) vs 80％ (16/20),P ＜ 0.05].Compared with the control group,the nutritional status of serum albumin and pre-albumin also showed a favourbale trends in the EEN group.Conclusions EEN can improve intestinal mucosal barrier and increase the weaning possibility in patients with mechanical ventilation.

Objective: To investigate the effect of UGT2B7 A268G and UGT2B7 G211T genetic polymorphism on serum drug concentration of valproic acid (VPA).
Methods:Genetic polymorphisms of UGT2B7 A268G and UGT2B7 G211T were tested in 248 epileptic patients by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). Data including basic information, epilepsy type, times and doses of drug, treatment response and liver and kidney functions were collected. Statistical analysis was performed by SPSS 13.0 through multivariate linear regression, one-way ANOVA,χ2 test, and paired T-test.
Results:Based on multivariate linear regression, there was no significant difference between gender, age, or body mass index and VPA, but concentration-to-dose ratios (CDRs) were positively correlated with VPA. hTe genetic polymorphisms of UGT2B7 A268G and UGT2B7 G211T were consistent with Hardy-Weinberg equilibrium. UGT2B7-268A>G allele frequency distribution A was 30.05%, and G was 69.95%. Variance analysis showed that serum drug concentration was significantly different in the genotype of AA, AG, or GG (F=5.477, P=0.005). Further analysis of paired T test showed that AA type was significantly different from GG type (P=0.048), and that serum concentration of AA type was much higher than that of GG type, while no signiifcant difference between AA type and AG type, GG type and AG type. UGT2B7 G211T allele frequency distribution G was 77.24%, and T was 22.58%. hTere was no signiifcant difference in standardized serum concentration among genotypes of GG, GT, and TT.
Conclusion:hTis study reveals UGT2B7 A268G genetic polymorphism distribution in Chinese epilepsy population. UGT2B7 A268G plays an important role in VPA’s metabolism, and has certain effect on VPA’s serum concentration. Epilepsy patient with this genotype should be adjusted the dose of VPA to make a therapeutic effect.
