Objective To observe the effect of core stability training combined with eye acupuncture on motor function in patients with hemiplegia after stroke.Methods Eighty patients with hemiplegia after stroke were randomly divided into a treatment group and a control group (40 cases in each).Both groups were given regular rehabilitation training, but the patients in the treatment group also were taught core stability training of their waist and abdominal muscle groups, their shoulder muscles, trunk and pelvis.They were also given eye acupuncture.A trunk control test (TCT) , Berg's balance scale (BBS), the modified Barthel index (MBI), functional ambulation categories (FACs) and the Fugl Meyer assessment scale (FMA) were used to assess motor function before and after treatment.Results At the end of 6 weeks of treatment, all of the measurements in both groups had significantly improved.The average TCT, BBS, MBI, FMA, and FAC scores of the treatment group significantly exceeded those of the control group.Conclusions Core stability training and eye acupuncture together can significantly improve the motor function of hemiplegic stroke survivors.The combination therapy is worthy of clinical popularization and application.

Aim To confirm the inhibitory effect of chronic intermittent hypobaric hypoxia ( CIHH) on my-ocardial apoptosis induced by metabolism syndrome ( MS) , and to investigate its mechanism. Methods A rat model of MS induced by fructose was used. The blood pressure and the plasma content of glucose, tri-glyceride, cholesterol, and insulin after 12 h fasting were detected. HE stain were used to detect the cardi-ac structure. The TUNEL staining and activity of caspase-3 were used to detect the apoptosis of myocar-dium. The protein expression of Bcl-2 and Bax was detected by Western blot . Results Compared with the control rats, the blood pressure and the plasma content of glucose, triglyceride, cholesterol, and insu-lin were all increased in rats with MS. In rats with MS, the impairment of cardiac structure and the increase of apoptosis were also observed. The protein expression of Bcl-2 was significantly down-regulated, and that of Bax was significantly up-regulated in MS rats. The ratio of Bcl-2/Bax was also significantly decreased. Interest-ingly, CIHH could ameliorate all of the above issues. There was no significant difference between control group and CIHH group. Conclusion CIHH may im-prove the increased apoptosis in rats with MS via inhib-iting the mitochondrial pathway of apoptosis. This stud-y might provide new targets for therapy and the preven-tion of MS patients.

BACKGROUND: Umbilical cord mesenchymal stem cells (UC-MSCs) are a group of cells that have self-renewal, highly proliferative and multidrug differentiation potential. The properties of UC-MSCs and their tumor tropism make them an ideal tool for glioma cell therapy. These cells can act by paracrine or as a delivery system for genes and drugs. It has been demonstrated that UC-MSCs can inhibit the growth of glioma and improve the survival after transplantation into the brain. OBJECTIVE: To summarize the molecular mechanisms and safety of UC-MSCs in the treatment of glioma and to provide a useful reference for further research. METHODS: We searched the PubMed and CNKI databases from 2000 to 2017 with the English terms of "glioma; umbilical cord mesenchymal stem cells" and the Chinese terms of "glioma; umbilical cord mesenchymal stem cells; safety; molecular mechanism". Based on the inclusion and exclusion criteria, 55 articles were finally reserved for review. RESULTS AND CONCLUSION: UC-MSCs have obvious effect on treating glioma. These cells can treat glioma through homing mechanism and paracrine mechanism as gene carrier and co-culture. Moreover, UC-MSCs have certain safety in the treatment of glioma.

We explored the status of Babesia infection in natural hosts in Fujian Province.Rodents in Fujian Province were captured by the night trapping method during 2014-2016.Heart blood samples were collected.At the same time blood samples of ox,goats and dogs were also collected,from which the fragments of 18S rRNA gene of Babesia were amplified by polymerase chain reaction (PCR).Data on infection rate were analyzed with Chi-square or Fisher exact test to indicate statistical significance.Results showed that 5 917 cages were laid and 381 rodents were captured,density of rodent was 6.44％.The o verall Babesia infection rate in rodents was 7.61％,while infection rate in domesticated rodents was 1.68％,and the infection rate in wide rodents was 12.87％.The infection rate was higher in wild rodents than that in domesticated rodents,and the statistical analysis result revealed a significant difference.The infection rates in region of Central Fujian and Eastern Fujian was high,and no infection was found in Southern Fujian region.The statistical analysis result revealed a significant difference in infection rate among different regions.The infection rate of goats and dogs were determined to be 1.79 ％ and 0.55 ％,and no infection was found in ox.The infection rate was higher in rodents than that in other host animals,and the statistical analysis result revealed a significant difference.It is suggested that the rodents,especially the wide rodents are the main natural hosts of Babesia.

OBJECTIVETo investigate the association between atrial fibrillation and the single nucleotide polymorphism (SNP) of slow delayed rectifier K(+) channel (I(Ks)) genes in Han nationality Chinese.

METHODSThree hundred and eighty of Han nationality Chinese (142 atrial fibrillation, 120 in-hospital and 118 out-hospital control) were enrolled in this study. Asian specific non-synonymous SNPs of KCNQ1 P448R, KCNQ1 R519H, KCNQ1 G643S, KCNE1 G38S and KCNE1 D85N were genotyped by restriction fragment length polymorphism analysis. A newly cloned KCNE4 gene was also screened for any possible SNP.

RESULTSThe minor allele frequency of KCNQ1 P448R, KCNQ1 R519H, KCNQ1 G643S, KCNE1 G38S and KCNE1 D85N in out-hospital subjects was 0.079, 0, 0.042, 0.317 and 0.004, respectively. None of these SNPs was relationed with any atrial fibrillation phenotype. A KCNE4 E145D was discovered and proven statistically to relation significantly to atrial fibrillation by logistic regression analysis (OR = 1.66, P = 0.044). The minor allele frequency of KCNE4 E145D was as high as 0.271 in out-hospital subjects.

CONCLUSIONSNone of the SNPs of KCNQ1 P448R, KCNQ1 R519H, KCNQ1 G643S, KCNE1 G38S and KCNE1 D85N was associated with atrial fibrillation phenotype, but KCNE4 E145D may relation to atrial fibrillation. The effect of KCNE4 E145D variation on the function of I(Ks) channel is to be determined.

OBJECTIVETo investigate the dynamic trend of specific antibody against severe acute respiratory syndrome (SARS)-CoV in serum collected at various periods among employees in Guangzhou Xinyuan animal market.

METHODSVolunteers from employees of the animal market were recruited and their serum specific antibody against SARS-CoV were determined by enzyme linked immunesorbent assay (ELISA) method.

RESULTSPositive SARS-CoV specific IgG antibody was found 25.61% (n = 328), 13.03% (n = 238), 12.59% (n = 135), 5.04% (n = 139) and 9.43% (n = 53) among volunteers, which were sampled in May 2003, Dec. 2003, Jan. 2004, July 2004 and June 2005 respectively. No specific IgM antibody was found in all of those samples. Among 129 samples which were tested twice or more, 97 were all negative, 18 all positive, 13 changed from positive to negative but only one sample from negative to positive. When the volunteers were divided by the duration of their working experiences as short-term or long-term, those who had worked at animal market for less than or more then 6 months when being tested, the positive rate for long-term employees were relatively constant, however, all of the persons employed after January 2004, when the palm civets and raccoon dogs were culled from the market, were tested negative.

CONCLUSIONThe prevalence of specific antibody against SARS-CoV in employees of the animal market were somehow related with the presence or absence of palm civet. No serum was tested positive for persons who were employed after palm civets and raccoon dogs were culled from market. This data indicated that the SARS-CoV might have been from the palm civets and raccoon dog, and the animal market seemed to serve as one of the sources of infection.

The present study was designed to investigate the role of opioid receptors in the vasorelaxation effect of chronic intermittent hypobaric hypoxia (CIHH) in thoracic aorta rings and the underlying mechanism in rats. Adult male Sprague-Dawley (SD) rats were randomly divided into 2 groups: CIHH treatment group and control group. The rats in CIHH group were exposed to hypoxia in a hypobaric chamber (simulated 5 000 m altitude) for 28 days, 6 h per day. The rats in control group were kept in the same environment as CIHH rats except no hypoxia exposure. The relaxation of thoracic aorta rings was recorded by organ bath perfusion technique, and expression of opioid receptors was measured by Western blot. Results are shown as follows. (1) The acetylcholine (ACh)-induced endothelium-dependent relaxation of thoracic aorta in CIHH rats was increased obviously in a concentration-dependent manner compared with that in control rats (P < 0.05). (2) This enhancement of ACh-induced relaxation in CIHH rats was abolished by naloxone, a non-specific opioid receptor blocker (P < 0.05). (3) The expressions of δ, μ and κ opioid receptors in thoracic aorta of CIHH rats were up-regulated compared with those in control rats (P < 0.05). (4) The enhancement of CIHH on relaxation of thoracic aorta was reversed by glibenclamide, an ATP-sensitive potassium channel (KATP) blocker (P < 0.05). The results suggest that opioid receptors are involved in CIHH-enhanced ACh-induced vasorelaxation of thoracic aorta through KATP channel pathways.
