Objective To investigate the influence of acupuncture on Nestin expression in the cerebral cor- tex of hypoxia-ischemic neonatal rats.Methods A total of 72 Sprague-Dawley(SD)rats aged 7 days were random- ly divided into three groups:A normal group(n=24),the hypoxic-ischemic encepbalopathy(HIE)group(n=24), and an acupuncture+HIE group(n=24).The rats were sacrificed at time points including 3d,7d,14d and 28d af- ter insult,their brains were removed and sections were made.Any nerve stem cells(NSCs)in the cerebral cortex were detected using immunohistochemical staining of Nestin.Results Nestin-positive cells were found in the cere- bral cortex in the normal neonatal SD rats early after birth.After HI insult,the Nestin-positive cells had increased in the injured areas of the cortex and in contralateral mirror areas,especially around the injured areas.Peak Nestin ex- pression was 3 days after insult.In the acupuncture+HIE group,Nestin positive cells were significantly increased when compared with that in the HIE group,the peak was postponed,and the peak was longer than in the HIE group. The Nestin positive cells decreased,were seldom seen,and were not different among three groups 28 days after the HI insult.Conclusions Endogenous neural stem cells in the cerebral cortex were increased by acupuncture in hy- poxia-ischemic in neonatal rats,and acupuncture made the peak of Nestin expression longer.

Objective To investigate the effects of methylprednisolone(MP) on the expression of matrix metalloproteinase(MMP)-9 and airway inflammation in murine models of asthma. Methods Thirty female BALB/c mice were randomly divided into asthma group,MP group and control group(n=10).Murine models of acute asthma were established by ovalbumin(OVA) via peritoneal injection and intranasal instillation.The pathological changes of lung tissues were observed with HE staining,and cell quantitation was conducted in bronchalveolar lavage fluid(BALF).The expression of MMP-9 protein was determined by immunohistochemistry and gelatin zymogram,and the expression of MMP-9 mRNA was detected by RT-PCR. Results Compared with control group,there were more significant airway spasm and more infiltration of inflammatory cells in histologic examination,and there was higher eosinophil cell quantitation in BALF in asthma group(P

Objective To observe any effect of intensive training on the degree of depression and the expression of Kalirin-7 in the hippocampus of rats modeling with post-stroke depression,and to investigatc possible mechanisms.Methods Forty male Wistar rats were randomly divided into a post-stroke depression (PSD) group,a routine training group,an intensive training group and a sham-operation group (n =10 for each group).All except the sham-operation group were given the middle cerebral artery occlusion using the intraluminal thread method,and chronic mild stress was applied.The PSD group and the sham-operation group were not given any training.The routine training group was trained oncc a day,and the intensive training group was trained twice a day.The sucrose preference test,open field test and forced swimming test were conducted at the outset and after 14 and 28 days of training.The expression of Kalirin-7 in the left hippocampus was detected using Western blotting.Results After 14 days of training,significant differences were found in the test results of the sham-operation group compared with the other groups (P＜0.05).There were also significant differences in the average results on all 3 tests among all of the groups except the sham-operation group.At both 14 and 28 days after training,the average expression of Kalirin-7 in both the routine and intensive training groups was significantly higher than in the PSD group (P＜0.05),and that of the intensive training group was significantly higher than that of the routine training group at the same time points (P＜0.05).Conclusion Intensive training can relieve depression and increase the expression of the Kalirin-7 in the hippocampus,at least in rats.

AIM:To analyze the characteristics of optical coherence tomography ( OCT ) in diabetic optic neuropathy ( DON ) retrospectively.
●METHODS:Retrospective study. A total of 175 cases of type ll diabetes with fundus lesions from Dec. 2013 to Dec. 2015 were selected and the clinical information was collected. These cases were diagnosed by consultation between Departments of Ophthalmology and Endocrinology in the Second Affiliated Hospital of Xi′an Jiao Tong University. The results of body examination were recorded and cases were examined by color fundus photography, fluorescein fundus angiography ( FFA) and OCT. All these data were analyzed.
●RESULTS: A total of 49 cases ( 90 eyes, 25. 7%) were diagnosed DON through FFA which manifested abnormal fluorescence in optic papilla. Results of OCT showed:among 90 eyes of DON patients, 15 eyes ( 16. 7%) had normal optic nerve form; 20 eyes(22. 2%) of excavation of optic disc became smaller or disappeared, with prelaminar tissue and peripapillary retinal nerve fiber layer (RNFL) swelling;26 eyes (28. 9%) manifested optic cup deep and cup/disc ratio increasing;18 eyes (20. 0%) had tissue hyperplasia in the hollow or on the surface of optic disc; 11 eyes(12. 3%) had symptoms including vitreous traction optic papilla and optic disc rim rising. DON eyes which had similar fluorescence features could manifest different tissue morph by OCT.
●CONCLUSION: FFA defines DON by change of blood circulation in optic nerve. However, OCT can show differences of tissue morph of optic nerve that FFA fails to do. So OCT can manifest the causes and sites of optic neuropathy more clearly and also provide basis for treatment. The advantages of OCT are conducive to reviews and curative effect tracking among DON patients and these advantages including noninvasive, convenient, inexpensive and repeatable.

OBJECTIVETo observe therapeutic effect of Shaoshanhuo needling method on periarthritis of shoulder.

METHODSOne hundred and twenty cases were randomly divided into two groups: a treatment group of 57 cases and a control group of 63 cases. The treatment group were treated with Shaoshanhuo needling method and massage combined with functional exercise of shoulder joint, and the control group were treated with warming acupuncture and moxibustion combined with massage and functional exercise of shoulder joint. Their therapeutic effects were evaluated after 2 courses.

RESULTSThe effective rate and the cured rate were 96.5% and 70.2% in the treatment group, and 88.9% and 50.8% in the control group respectively, with no significant difference between the two groups in the effective rate (P>0.05), but with a significant difference between the two groups in the cured rate (P<0.05), the treatment group being higher than the control group.

CONCLUSIONShaoshanhuo needling method has a better therapeutic effect on periarthritis of shoulder.

Objective: To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. Methods : The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model. Results: Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. Conclusions The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

ObjectiveTo investigate the neuropsychological impairments and risk factors that caused cognitive disturbance in patients with silent brain infarction (SBI). Methods36 SBI subjects and 25 normal controls were compared on a comprehensive neuropsychological test battery. Logistic regression was used to analysis the risk factors. ResultsThe SBI group scored lower on the visual retention test (VRT), the WAIS RC full scale IQ, standard scores of the perceptual organization factor and memory/attention factors than did the control group. The score of self rating depression scale (SDS) was higher in SBI group. Hypertension and leukoaraiosis (LA) were correlates of cognitive impairment in logistic regression analyses. Conclusions SBI has some degree of neuropsychological impairment, especially deficits of visuospatial ability, disturbance of perceptual organization, memory and attention, and some degree of depression. Hypertension and LA independently contribute to the risk factors of cognitive disturbance.
