BACKGROUND:Whether embryonic stem cel transplantation can be an effective method for treatment of cerebrovascular disease has become a hot spot. OBJECTIVE:To investigate the effect and feasibility of embryonic stem cel-differentiated neural precursor cel transplantation for the treatment of cerebrovascular disease. METHODS:The rat models of Parkinson’s disease, ischemic brain injury and vascular dementia were established and the embryonic stem cells were in vitro cultured and induced to differentiate into the neural precursor cells. The embryonic stem cel-differentiated neural precursor cells were transplanted into the rat brains with corresponding cerebrovascular disease, and then the rotational behavior changes, pathological changes in the brain tissue as wel as changes in the hippocampal structure and the number of nerve cells in the rats with cerebrovascular disease were observed. RESUTLS AND CONCLUSION:After the embryonic stem cel-differentiated neural precursor cells transplanted into the rat brains with Parkinson’s disease, the frequency of apomorphine-induced rotation was decreased and in the downward trend, while the striatal dopamine levels were significantly increased. After transplantation of embryonic stem cel-differentiated neural precursor cells into the rat brains with ischemic brain injury, the cells could survive for a long time, and then migrated and distributed in the injured hippocampus to form the hippocampal structure;the cells could differentiate into neurons, and the number of nerve cells in the injured hippocampus was significantly increased. The results indicate that the transplanted glial cel line-derived neurotrophic factor gene-modified embryonic stem cells can improve the learning and memory function of vascular dementia rats, enhance neural plasticity, and induce self-directed migration and differentiation into mature neurons.

Objective To investigate the clinical curative effect of oral and acupoint application of traditional chinese medicine combined with Azithromycin for the children with Mycoplasma Pneumonia. Methods A total of 160 children with mycoplasma pneumonia were divided into two groups according to digital random table method, with 80 cases in each group. The patients of the two groups were given conventional treatment to relieve cough and reduce phlegm; On the basic treatment of conventional treatment, the control group were treated with azithromycin, wile the treatment group were treated with oral traditional chinese medicine Tinghuang runfei decotion and acupointion application of Tinglizi, Baijiezi, Shengnanxing, Dahuang, and Bingpian. The treatment of both groups last 3 weeks. The time of defervescence, the disappearance time of cough and pulmonaryrales of the two groups were compared, and the serum levels of inter leukin 8 (IL-8), tumor necrosis factor-a (TNF-a), thrombin regulatory proteins (TM), D-dimer were compared before and after treatment. The total effect rate and the incidence of adverse events were compared.Results The defervesce time (3.79 ± 1.68 dvs. 4.88 ± 1.61 d,t=3.846), disappearance time of cough (8.21 ± 2.42 dvs. 10.35 ± 2.60 d,t=5.389) and disappearance time of pulmonary rales (6.21 ± 1.89 dvs. 7.78 ± 2.08 d,t=4.997) in the treatment group were significantly less than those in the control group (P<0.01). The levels of IL-8 (9.98 ± 4.26 ng/Lvs.14.18 ± 4.82 ng/L, t=5.840), TNF-a (20.78 ± 5.93ng/Lvs. 26.07 ± 6.42 ng/L,t=5.414), TM (9.63 ±  2.88μg/Lvs. 13.08 ± 3.37μg/L,t=6.961), D-dimer levels (0.09 ± 0.04 ng/Lvs. 0.15 ± 0.06 ng/L,t=7.442) the treatment group were significantly better than those in the control group (P<0.01). The total effect rate in the treatment gruop was significantly higher than that of the control group (97.5%vs. 88.8%;χ2=4.783,P=0.029), but there was no significant difference in the incidence of adverse events between the two groups (16.3%vs. 10.0%;χ2=1.370,P=0.272).Conclusions Oral and acupointion of traditional chinese medicine Tinghuang runfei decotion combined with azithromycin could relieve the symptoms, improve the clincal effect and show its safety for the children with mycoplasma pneumonia.

Objective To explore the significance of IL-17 and IL-10 in patients with different types of hepatic cystic echinococcosis ( CE ) in cyst stages , to investigate the values of evaluation of hydatid cyst activity . Methods 33 patients with hepatic hydatid disease and 21 healthy people (control group) were enrolled, divided into 4 groups, according to WHO ultrasonic classification for CE:Control group (n=21), CEⅠ,Ⅱgroup (active, n=14), CEⅢgroup (transitional, n=10), and CEⅣ,Ⅴgroup (inactive, n=9). The serum concentrations of IL-17 and IL-10 were measured by enzyme-linked immunosorbent assay. Results Serum levels of IL-17 in CEⅢgroup were significantly higher than other groups (P<0.05). There were no significant difference in serum IL-17 levels between CEⅠ,Ⅱgroup [(38.57 ± 3.83) pg/mL] and CEⅣ,Ⅴgroup [(40.22 ± 5.15) pg/mL]. Serum levels of IL-10 were significantly higher in CEⅢgroup [(14.65 ± 2.15) pg/mL] than CEⅠ,Ⅱgroup [(11.38 ± 0.71) pg/mL] (P<0.05), while CEⅠ,Ⅱgroup were significantly higher than CEⅣ,Ⅴgroup [(7.60 ± 0.46) pg/mL] (P<0.05). There were no significant difference of IL-17/IL-10 ratio between CEⅠ, Ⅱgroup (3.44 ± 1.04) and CEⅢgroup (4.60 ± 2.40), and there were no significant difference of IL-17/IL-10 ratio between CEⅢgroup and CEⅣ,Ⅴgroup (5.39 ± 1.95). IL-17/IL-10 ratio in CEⅠ, Ⅱgroup was significantly lower than CEⅣ, Ⅴgroup (P<0.05). The serum concentrations of IL-17 has no correlation with IL-10 in different cyst stages. Conclusions The synergy effect of IL-17 and IL-10 may play the certain role to promote the parasite progress. Neither IL-17 nor IL-10 level could be as an independent marker of echinococcal cysts activity, while IL-17/IL-10 ratio reflect the hydatid cyst activity in certain degree, but as a echinococcal cysts activity marker, further evidence should be needed.

OBJECTIVEThis study aims to explore the method that uses primary tumor contralateral facial artery musculocutaneous (FAMM) flap to reconstruct defects of the tongue and floor of mouth.

METHODSSix cases were selected for the use of primary tumor contralateral FAMM flap to reconstruct tongue and floor of mouth defects after tumor resection.

RESULTSThe FAMM flap of the six cases had a long pedicle that could reach the contralateral tongue and floor of mouth. All flaps were intact until post-operation. All patients experienced post-operation complications, such as temporary facial tension and limited mouth opening, which improved after 3 months. Half a year later, the flaps still did not show signs of shrinking.

CONCLUSIONFeatures of the primary tumor contralateral FAMM flap include the tissue-like material provided for reconstructing tongue or floor of mouth defects, easy acquisition, and high survival rate with minimal donor site morbidity. As such, it is an ideal material for repairing tongue and floor of mouth defects.

ObjectiveTo investigate the association between ZJU index and the onset of nonalcoholic fatty liver disease （NAFLD） in the Uygur population and the value of ZJU index in predicting the risk of NAFLD. MethodsThe Uighur community of The 51st Regiment of The Third Division of Xinjiang Kashgar Corps was selected as the investigation site， and the Uygur residents who lived in this area and had an age of >18 years were selected as subjects. Follow-up studies were conducted in 2019， 2020， and 2021， and the investigation of outcomes was completed in June to August of 2021. Finally 10 597 subjects were enrolled for analysis. The Kruskal-Wallis H test was used for comparison of continuous variables between groups， and the chi-square test was used for comparison of categorical variables between groups. The subjects were divided into Q1-Q4 groups according to the level of ZJU index. The Kaplan-Meier curve was used to predict the incidence rate of NAFLD， and the Cox regression model was used to analyze the association between ZJU index and the risk of NAFLD； the area under the ROC curve （AUC） was used to evaluate the value of ZJU index in predicting the risk of NAFLD. ResultsDuring the median follow-up time of 4.92 years， the incidence rate of NAFLD was 9.4% （992/10 597） among the study population. After adjustment for multiple factors， there was a significant increase in the risk of NAFLD with the increase in ZJU index， with a hazard ratio of 2.55 （95% confidence interval ［CI］： 1.60‍ — ‍4.06）， 7.32 （95%CI： 4.78‍ — ‍11.20）， and 21.74 （95%CI： 14.32‍ — ‍33.00）， respectively （all P_trend<0.001）. The ROC curve showed that ZJU index had a higher value in predicting NAFLD （AUC=0.816）， and the male subgroup had a significantly higher predictive accuracy of ZJU index than the female subgroup （AUC： 0.829 vs 0.809）. ConclusionZJU index is a predictive factor for the onset of NAFLD in the Uygur population in rural areas of Xinjiang and has a good value in predicting the risk of NAFLD.
