A total of 192 poststroke patients with depression and anxiety were assigned randomly into study group (n =96) and control group (n =96).The study group received both capsules Shugan-jieyu and paroxetine while the control group paroxetine alone.Compared with the control group,scores of both Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) were significantly different at the end of week 2 and 6 in the study group (P ＜ 0.05).The HAMD and HAMA deduction rate and the scores of mangled extremity severity,mini-mental state examination and modified Barthel index at the end of week 6 of the study group were better than those of the control group (all P ＜ 0.05).The combined use of capsules Shugan-jieyu and paroxetine could improve symptoms of depression and anxiety,offer a higher safety and accelerate the rehabilitation of extremity function.

Objective To explore the influence of the combination therapy of probucol with atorvastatin on levels of serum high sensitivity C-reactive protein (hs-CRP), oxidized low-density lipoproteins (ox-LDL), and marix metallopro? teinase-9 (MMP-9) and resolution of carotid plaque in patients with acute cerebral infarction (ACI). Methods One hun? dred-six patients with acute cerebral infarction who had carotid artery color Doppler ultrasound-confirmed atherosclerot? ic plaques , were included in the present study. The patients were randomly divided into two groups: conventional treat? ment group ( 40 cases) which received atorvastatin (20mg/d) and co-treatment group (40 cases) which received Atorvas? tatin (20mg/d) and Probucol (500mg/d). Levels of hs-CRP, ox-LDL and MMP-9 were detected in all patients before treat? ment and 1, 6 and 12 months after drug therapy. The Intima-media thickness, area and numbers of carotid plaques were evaluated by using Doppler ultrasonography during a 12 months follow-up period. Results ① Serum hs-CRP and MMP-9 levels were significantly decreased at 1, 6 and 12 months after treatment, (conventional treatment group:t =14.662, 23.586, 28.179 and co-treatment group:t =47.023, 50.239, 50.774,P <0.01). The ox-LDL levels was obviously de? creased in the combined treatment group (t =4.592, 5.011, 5.892,P <0.01) but not in conventional treatment group (P > 0.05) at 1, 6 and 12 months after treatment. Serum hs-CRP, ox-LDL and MMP-9 levels were significantly lower in com? bined treatment group than in the conventional treatment group at all time points after treatment (t =7.655, 5.271, 2.492, t =4.927, 3.772, 4.673 andt =16.862, 4.251, 2.045.P <0.01 orP <0.05). ②There were not statistically differences in the IMT, plaque area and plaque numbers between these two groups before treatment (P >0.05). The IMT, plaque area and plaque numbers were significantly smaller in combined treatment group than in conventional treatment group (t =6.117, 3.290, 2.158,P <0.05). Conclusions The combination therapy of probucol with atorvastatin can greatly reduce levels of serunl hs-CRP,ox-LDL and MMP-9, indicating that the combination therapy has a strong anti-oxidant function, thereby reversing and stabilizing the atherosclerosis plaque.

Objective To understand the prevalence and distribution features of mild cognitive impairment(MCI)among elderly in Xinjiang Uygur and Han ethnic groups so as to provide evidence for etiological study and prevention. Methods From July 2007 to October 2008, according to the criteria of DSM-IV for MCI,a randomized, stratified and cluster sampling procedure was used in the Uygur and Han elder people aged ≥60 years in south Xinjiang, east Xinjiang and Urumchi region. Results A total of 2986 people were surveyed, including 1519 Uygur people and 1467 Han people, and 1435 males and 1551 females. (1) According to the age composition of national census in 2000, the total crude prevalence rate of MCI was 10.21%, and the total standardized prevalence rate of MCI was 10.58% in Uygur and Han elder people. In general Uygur and Han population, the crude prevalence rates of MCI were 9.61% and 10.84%, and the standardized prevalence rates of MCI were 10.29%and 10.86%, respectively. The prevalence of MCI was higher in Han population than in Uygur population, but there was no statistical difference(χ~2 = 1.225, P>0.05). (2) In males and females, the crude prevalence rates of MCI were 9.34% and 11.03%, and the standardized prevalence rates of MCI were 9.26% and 11.62%, respectively. There was no difference in prevalence rate between different sex populations(χ~2 =2.314,P>0.05). (3) In elder people aged 60～69, 70～79 and≥80 years, the MCI prevalence rates were 6.83%, 13.22% and 22.22% in Uygur population and 8.64%, 12.50% and 19.30% in Han population, respectively, and the prevalence rate of MCI was increased with aging in the two thnic roups(χ_(for trend)~2=34.753, 14.081, both P<0.05). (4)There were statistical differences in prevalence rates of MCI among different education levels, and it was decreased with enhancement of education levels in Uygur and Han population(χ_(for trend) = 14.785, 21.059, both P<0.05). Conclusions In Xinjiang Uygur and Han ethnic elderly people, the prevalence rates of MCI are significantly different among elderly with different ages and education levels, and it is increased with aging, but is decreased with enhancement of education levels.

Objective To observe the incidence of malnutrition, the therapeutic effect of nutritional support and the prognosis of patients with chronic obstructive pulmonary disease (COPD) under mechanical ventilation (MV) in patients with different traditional Chinese medicine (TCM) syndrome types and discuss the relationships between these indicators and the differentiation of cold-heat/deficiency-excess syndrome. Methods One hundred and three patients with COPD and MV admitted to Zhuji Hospital of TCM from September 2015 and July 2017 were enrolled, according to the different TCM syndromes, they were divided into an excess-heat syndrome group 42 cases and an asthenia-cold syndrome group 61 cases, and the differences in nutrition indexes and prognosis between the two groups were compared. Results The acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) score, nutritional risk screening 2002 (NRS2002) score and the incidence of malnutrition in excess-heat syndrome group were significantly lower than those in the asthenia-cold syndrome group, while the body mass index (BMI) in excess-heat syndrome group was obviously higher than that in the asthenia cold syndrome group [APACHE Ⅱ score: 20.1±5.4 vs. 22.0±3.4,NRS2002 score: 5.2±0.6 vs. 6.2±0.8, incidence of malnutrition: 61.9% (26/42) vs. 80.3% (49/61), BMI (kg/m2): 22.6±3.8 vs. 19.9±4.8, all P < 0.05]. The levels of albumin (Alb), prealbumin (PA) and transferrin (TF) of the excess-heat syndrome group were higher than those in the asthenia-cold syndrome group, and the differences between the two groups were statistically significant on the 7th day under MV [Alb (g/L): 36.14±2.97 vs. 34.40±3.37, PA (mg/L): 237.67±28.01 vs. 185.34±30.86, TF (g/L): 2.13±0.38 vs. 1.95±0.12, all P < 0.05]. In the excess-heat syndrome group, the percentage of weaning from MV was higher than that of the asthenia-cold syndrome group [85.7% (36/42) vs. 65.6% (40/61)], the 28-day mortality [14.3% (6/42) vs. 31.1% (19/61)] and ICU stay time (days: 9.21±2.96 vs. 11.13±3.96) were lower than those of the asthenia cold syndrome group (all P < 0.05). Conclusion The analysis of TCM differentiation of cold-heat/deficiency-excess syndrome has a certain reference value to realize the changing rules in nutritional status and prognosis of patients with COPD under mechanical ventilation.

Objective Platelet-to-lymphocyte ratio(PLR) has been proved to be a new biomarker of inflammation in various diseases. The purpose of this study was to explore the relationship between PLR and early neurological deterioration(END) in patients with acute ischemic stroke(AIS). Methods We retrospectively analyzed the clinical and laboratory data of 1 116 patients with AIS admitted to the Department of Neurology of Shanghai Yangpu District Central Hospital from May 2018 to October 2020.The patients were grouped for analysis according to whether END occurred within 72 hours. They were also grouped by the quartiles of PLR(platelet count divided by lymphocyte count). Univariable and multivariable logistic regression analyses were used to explore independent factors influencing END in patients with AIS. The predictive ability of PLR for the occurrence of END was evaluated by using a receiver operating characteristic(ROC) curve. Results A total of 1 116 patients with AIS were included in the study,with 125 patients(11.2%) in the END group and 991 patients(88.8%) in the non-END group. The univariable analysis showed that PLR in the END group was significantly higher than that in the non-END group(151.68 vs 132.89,P<0.05). The multivariable analysis showed that the risks of END in the PLR Q3 and Q4 groups were 2.172 times[odds ratio(OR)=2.172,95% confidence interval(CI) 1.201-3.929,P=0.01)]and 2.571 times(OR=2.571,95%CI 1.441-4.589,P=0.001) that of the PLR Q1 group. According to the ROC curve,the area under the curve for PLR predicting END was 0.587(95%CI 0.536-0.639,P< 0.001),and the optimal critical value was 119.40,with a sensitivity of 77.6% and a specificity of 39.4%. Conclusion PLR is an independent risk factor for END in patients with AIS. The increase of PLR is associated with a higher risk of END,which demonstrates certain predictive ability of PLR for the occurrence of END.

Objective To investigate the impact of ultrasound-targeted microbubble destruction ( UTMD) combined with carboplatin sustained release microspheres on the temperature of the tumor microenvironment and the concentration of the drug release in target tumor . Methods Twenty tumor bearing rabbits were randomly assigned into 4 groups : the control group without any treatment ; the carboplatin-loaded PLGA microspheres (CPMs) group ,only intratumoral injection of carboplatin sustained-release microspheres ;the S2000 group ,diagnostic ultrasound irradiation using S2000 equipment on local chemotherapy tumor tissue combined with lipid microbubbles ;the AP-170 group ,the same treatment as the S2000 group except the application of AP-170 instead of S2000 . Far-infrared thermography was performed to measure the tumor temperature . The experimental equipment of extracorporeal circulation was set up . The experimental conditions were assigned into 4 groups :37℃ CPMs group ,37℃ S2000 group ,37℃ AP-170 group ,40℃ AP-170 group . After irradiation experiment ,the carboplatin absorbance was measured at 229 nm wavelength . The absorbance difference of each group was compared with the 37℃ CPMs group ,and each group was tested 10 times . Results The intratumorous temperature in AP-170 group increased to (40 .24 ± 0 .72) ℃ ,which was significantly different from all the other groups ( P ＜ 0 .01).The in vitro drug release experiment showed that the absorbance in the 40 ℃ AP-170 group was 0 .1537 ± 0 .0094 ,which was significantly different from other groups ( P ＜ 0 .01).Higher temperature promoted the release of chemotherapeutic drugs from carboplatin sustained-release microspheres , thus enhanced the chemotherapeutic effect .This might be the mechanism that UTMD affects the microenvironment in this experiment .Conclusions UTMD increases the permeability of tumor cells .The increase of temperature promotes more drugs into the microenvironment of tumor cells .Thus ,the local chemotherapeutic effect is enhanced in the tumor .
