Methods:The determination of antimicrobial effectiveness of 10% chloral hydrate solution from two different manufacturers was carried out according to Chinese Pharmacopoeia (2015 edition). Results:The antimicrobial effectiveness of 10% chloral hydrate solution met the require-ments of Chinese Pharmacopoeia (2015 edition). Conclusion:10% Chloral hydrate solution shows adequate antimicrobial effective-ness.

Objective:To investigate the prognostic values of tumor–stroma ratio and tumor-infiltrating lymphocytes in colorec-tal cancer. Methods:A total of 218 stageⅡorⅢprimary colorectal cancer patients were analyzed for the tumor–stroma ratio (TSR) and tumor-infiltrating lymphocytes (TIL) by using HE stained histological sections. The relationship between TSR and clinicopatholog-ic variables and the difference in clinical outcomes of different groups were also analyzed. Results:Overall survival rates for the stro-ma-low group were significantly higher than the stroma-high group in stagesⅡandⅢcolorectal cancer (P＜0.05). However, the differ-ences in TSR were not correlated with clinicopathologic features such as gender and age (P>0.05). Overall survival rates of patients with high TIL were significantly higher than patients with low TIL (P＜0.05). Patients with high TIL had notable better prognosis than patients with low TIL (P＜0.05) in the stroma-low group. Conclusion:TSR and TIL are independent prognostic factors for stagesⅡandⅢcolorectal cancer. The combined estimates of TSR and TIL in routine pathology diagnoses may provide more evidence to predict the prognosis of stagesⅡandⅢcolorectal cancer.

Objective To observe the effect of dual-task interference on postural sway and hand flexibility of patients with early Parkinson's disease (PD).Methods Twenty-tree patients with early PD and twcnty-three healthy,sex-and age-matched control subjects were examined.Postural sway was measured with an accelerometer at the centre of mass at the lower spine.Two parameters of postural sway were computed from the acceleration signals including root mean square acceleration (RMS) and jerkiness of sway (JERK).Purdue pegboard test,single-task tests and dual-task test were performed respectively to record the numbers of nails inserted with left hand,right hand and both hands within 30 seconds.Results In the usual conditions,no significant differences of postural sway parameters were found between the control group and PD group in eye open and eye closed condition.In dualtask condition,PD patients showed an increase of RMS values (eye open conditions:PD group (0.156±0.112) m/s2,control group (0.086±0.026) m/s2;eye closed conditions:PD group (0.204±0.162)m/s2,control group (0.095±0.023)m/s2) of sway acceleration,compared with control subjects (P＜0.01).These differences reached significance during cognitive task performance in eye open and eye closed with dual task.PD patients showed larger JERK values with increasing difficulty of the sway task which also reached significance during cognitive task performance(P＜0.05).The number of pegs inserted within 30 s in patients with PD (17.33±4.87)was significantly lower than that in controls (20.77±4.13) (P＜0.05).Conclusion The hand flexibility of patients with early PD obviously decrease.The balance of patients with early PD may deteriorate when their attention is diverted or reduced because of attempting to perform cognitive tasks.

Objective To investigate the effects of climate change on the geographical distribution of Astragalus membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao in Gansu Province,and predict its potential habitat;To provide a theoretical basis for resource conservation of cultivation of A.membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao.Methods Based on the distribution data of A.membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao from field surveys,the maximum entropy model and geographic information system were used to simulate its potential habitat in Gansu Province for the current(1970-2000)and future(2041-2060)periods,and the contribution of environmental factors and the results of the knife-cut test were integrated to assess the important factors governing the distribution of A.membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao.Results The dominant environmental variables governing the geographical distribution of A.membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao were precipitation in the wettest month,average temperature in the wettest season,and elevation.The potential suitable area of A.membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao in Gansu Province under current climatic conditions was 65 902.66 km2,and the high suitable area was mainly concentrated in Dingxi District.In the future period,the suitable areas of A.membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao under the scenarios of SSP126,SSP370 and SSP585 all showed a decreasing trend,especially the area of the high suitable areas decreased significantly.Conclusion Future climate change will lead to a significant reduction in the suitable habitat for A.membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao in Gansu Province.The suitable habitat will mainly move towards high-altitude mountainous areas,and the continuity of A.membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao resources can be maintained by establishing ecological protection zones.

BACKGROUND/OBJECTIVES: The study examined the association between homocysteine and diabetes mellitus in patients with H-type hypertension and assessed the possible effect modifiers. SUBJECTS/METHODS: This cross-sectional study included 1,255 eligible participants in the ‘H-type Hypertension Management and Stroke Prevention Strategic International Science and Technology Innovation Cooperation Project’ among rural Chinese people with H-type hypertension. A multivariate logistic regression model was used to evaluate the relationship between homocysteine and diabetes mellitus. RESULTS: The mean level of total homocysteine (tHcy) in the diabetes mellitus population was 19.37 μmol/L, which was significantly higher than the non-diabetic patients (18.18 μmol/L). When tHcy was analyzed as a continuous variable, the odds ratio (OR) of diabetes was 1.17 (95% confidence interval [CI], 1.01–1.35; per interquartile range). When tHcy was stratified according to the quintile, the ORs for diabetes were 2.86 (95% CI, 1.22–6.69) in the highest quintile (tHcy ≥ 20.60 μmol/L) compared to the reference group (tHcy < 12.04 μmol/L). When tHcy was grouped by 15 μmol/L and 20 μmol/L, patients with tHcy ≥ 20 μmol/L had a significantly (P = 0.037) higher risk of diabetes (OR, 2.03; 95% CI, 1.04–3.96) than in those with tHcy < 15 μmol/L. Subgroup analysis showed that the tHcy-diabetes association was unaffected by other variables. CONCLUSION In this study of rural Chinese people with H-type hypertension, the tHcy levels showed a positive association with diabetes mellitus. This independent association is unaffected by other potential risk factors.

OBJECTIVE To explore the potential geographic distribution of Pinellia Ternata (Thunb.) Breit. in Gansu province, clarify its habitat requirements, and provide a theoretical basis for rational cultivation. METHODS Based on 100 geographic distribution points of Pinellia Ternata (Thunb.) Breit. and 39 environmental variables (including 19 bioclimatic variables, 17 soil variables and 3 topographic variables), the maximum entropy model(MaxEnt) and ArcGIS geographic information system software were used to make the habitat suitable for its evaluation and classification of suitable areas, the result of Jackknife test was used to evaluate the environmental variables that affect the habitat of Pinellia Ternata (Thunb.) Breit., the area under the ROC curve(AUC) was used to evaluate the degree of reliability of the prediction results. RESULTS The AUC was 0.993, indicating that the prediction results of the MaxEnt model were reliable. Monthly average daily temperature difference, isotherm, standard deviation of seasonal variation of temperature, annual precipitation, the wettest month precipitation, the driest month precipitation, the driest season precipitation, the coldest season precipitation and altitude were the main environmental variables affecting the growth of Pinellia Ternata (Thunb.) Breit.. The suitable areas for Pinellia Ternata (Thunb.) Breit. in Gansu were mainly concentrated in Longnan, Tianshui and Pingliang, where the areas of high, medium and low suitable areas were 16 180.4, 15 413.96, 21 204.84 km2, respectively. CONCLUSION The research results can provide a theoretical reference for the protection and standardized cultivation of Pinellia Ternata (Thunb.) Breit. resources.
