Objective: To observe the influence of acupuncture at Zusanli (ST 36) and Xuanzhong (GB 39) on cerebral vasomotoricity of ischemic stroke and its possible mechanism.Methods: All the appropriate cases were randomly divided into treatment and control groups with 80 cases in each group. The routine treatment of cerebral apoplexy was given to the two groups. Zusanli (ST 36) and Xuanzhong (GB 39) were added to the treatment group. The change of velocity of blood blow of the cerebral central artery was observed by transfrontal Doppler ultrasound detecting method before and after treatment to evaluate the cerebral basomotoricity of the patients. Results: The cerebral vasomotoricity in the treatment group was greatly improved compared with pre-treatment (P＜0.05) and there was a significant difference compared with the control group (P＜0.05). Conclusion: Acupuncture at Zusanli (ST 36) and Xuanzhong (GB 39) could obviously improve the cerebral vosomotoricity of the patients with cerebral ischemic stroke, which might be one of the action mechanisms of acupuncture treatment for cerebral ischemic stroke.

Objective To investigate the predictive value of inflammatory cells and clinical features in the prognosis of immune checkpoint inhibitors (ICIs) treating non-small cell lung cancer (NSCLC).Methods The data of 163 cases of stage Ⅲ and Ⅳ NSCLC patients treated with the ICIs in this hospital from January 1,2017 to December 31,2022 were collected.The CT examination was conducted after 6-8 weeks treatment.The pa-tients were divided into the objective remission group[complete remission (CR)+partial remission (PR)]and non-objective remission group[stable disease (SD)+progressed disease (PD)],disease control group (CR+PR+SD) and non-disease control group (PD),persistent clinical benefit group (DCB) and non-DCB group.The differences in clinical features and inflammatory cells indicators were compared among the differ-ent groups.The receiver operating characteristic (ROC) curve was adopted to evaluate the predictive efficiency of the inflammatory cells indicators for DCB.The influencing factors analysis of progression free survival (PFS) time and overall survival (OS) time adopted the Cox regression analysis.Results The lymphocyte count (ALC) in the disease control group was higher than that in the non-disease control group.The neutro-phil to lymphocyte ratio (NLR),platelet-lymphocyte ratio (PLR) and mononuclear lymphocyte ratio (MLR) were lower than those in the non-disease control group.The proportions of squamous cell carcinoma,stage Ⅲ,ECOG score 0-1 point,adverse reactions in the DCB group were higher than those in the non-DCB group (P<0.05),the PLT count,NLR,PLR and MLR were lower than those in the non-DCB group (P<0.05). The ROC curve analysis results showed that PLT,NLR,PLR and MLR could serve as the indicators for pre-dicting DCB,the area under of ROC curve (AUC) was 0.633,0.602,0.635 and 0.604 respectively,the opti-mal cut off values were 187×109/L (P=0.004),5.0 (P=0.026),235 (P=0.003) and 0.35 (P=0.024) re-spectively.The multivariate Cox regression analysis showed that non-squamous carcinoma including adenocar-cinoma (HR=1.565,95％CI:1.057-2.316) and other pathologic types (HR=2.285,95％CI:1.326-3.936),ECOG score 2-3 points (HR=2.375,95％CI:1.652-3.415),AMC≥0.65×109/L (HR=1.847,95％CI:1.160-2.938) and PLR≥235 (HR=1.557,95％CI:1.016-2.386) were the independent risk factors for short PFS.The ECOG score 2-3 points (HR=4.615,95％CI:2.882-7.391),AMC≥0.65×109/L (HR=5.161,95％CI:2.984-8.925) and PLR ≥235 (HR=1.732,95％CI:1.059-2.833) were the independent risk fac-tors for short OS (P<0.05),and having adverse reactions (HR=0.472,95％CI:0.294-0.757) was the independ-ent protective factor for short OS (P<0.05).Conclusion Lower PLT,AMC,NLR,MLR and PLR,higher ALC,squamous cell carcinoma,TNM stage Ⅲ,ECOG score 0-1 point and immunotherapy related adverse reactions could prompt that the prognosis is good in ICIs treating advanced NSCLC.PLT,NLR,PLR and MLR could serve as the indicators for predicting DCB.

Objective Less surveys on the economic burden of hepatitis B (HB)-related diseases have been conducted in China,so the socioeconomic harm caused by the diseases is not clear and the key parameters for economic evaluation of hepatitis B prevention and treatment are lacking.This study aimed to analyze the direct,indirect and intangible expenditures of hospitalized patients with HB-related diseases during hospitalization and during a year in different areas of China.Methods The hospitals for infectious diseases and the large general hospitals in 12 areas in China were selected in the study.All the inpatients with HB-related diseases were surveyed by cluster sampling of consecutive cases.The direct expenditure included direct medical cost and direct non-medical cost.The indirect expenditure,including work loss of patients and caregivers,were calculated by using human capital method for urban and rural populations in 12 areas.The intangible expenditure were reflected by willing to pay and stochastic tournament.The influencing factors of direct and indirect costs were identified by stepwise linear multi-variation regression analysis.Results A total of 27 hospitals in 12 areas were included in the survey.A total of 4 718 cases were surveyed,the overall response rate was 77.7％.The average hospital stay was 29.2 days (27-34) and the hospitalization expenditure was averagely 16 832.80 yuan (RMB) per case,in which the highest proportion (61.2％)was medicine fees [10 365.10 yuan (RMB)].The average direct expenditure and indirect expenditure were consistent with the severity of illness,which were 18 336.10 yuan (RMB) and 4 759.60 yuan (RMB) respectively,with the ratio of 3.85:1.The direct medical expenditure [17 434.70 yuan (RMB)] were substantially higher than the direct non-medical expenditure [901.40 yuan (RMB)].It was found that the hospitalization expenses was highest in direct medical expenditure and the transportation expenses was highest in direct non-medical expenditures.Among the average indirect expenditure,the loss of income for the patients [3 832.50 yuan (RMB)] was higher than that for the caregivers [927.20 yuan (RMB)],The total direct and indirect expenditure was highest for liver transplantation,followed by severe hepatitis,hepatocellular carcinoma and decompensated cirrhosis,acute hepatitis B,compensated cirrhosis and chronic hepatitis B.The influencing factors for both direct and indirect expenditure were high hospital level,severity of hepatitis B,living in urban area,antiviral therapy,long hospitalization and monthly income of family.For average 3.74 outpatient visits and 1.51 hospitalization,the average annual direct,indirect and intangible expenditure for HB-related diseases were 30 135.30,6 253.80 and 44 729.90 yuan (RMB) [totally 81 119.00 yuan (RMB)],accounting for 37.3％,7.7％ and 55.0％,respectively.Of the annual direct medical expenditure [28 402.80 yuan (RMB)],which were much higher than non-medical expenditure [1 732.50 yuan (RMB)],hospitalization expenditure [26 074.20 yuan (RMB)] was higher than outpatient visit expenditure [4 061.10 yuan (RMB)].The annual indirect expenditures for outpatient visit and hospitalization were 763.60 and 5 490.10 yuan (RMB),respectively.Of the annual intangible expenditure,the highest was that for/primary hepatocellular carcinoma,followed by cirrhosis,chronic hepatitis B,severe hepatitis B,liver transplantation and acute hepatitis B.Conclusions A heavy economic burden has been caused by HB-related diseases in China,and patients are more likely to rely on medical service rather than non-medical service.It is necessary to take effective treatment measures to prevent the adverse outcome of HB related diseases and achieve significant economic benefits.The influence of HB related diseases on mental health of the people can be reflected by an economics term,intangible expenditure.

Objectives:This study aimed to evaluate the effect of the strategies on COVID-19 outbreak control in Shenzhen, and to clarify the feasibility of these strategies in metropolitans that have high population density and strong mobility.Methods:The epidemic feature of COVID-19 was described by different phases and was used to observe the effectiveness of intervention. Hierarchical spot map was drawn to clarify the distribution and transmission risk of infection sources at different time points. The Susceptible-Exposed-Infectious-Asymptomatic-Recovered model was established to estimate case numbers without intervention and compare with the actual number of cases to determine the effect of intervention. The positive rate of the nucleic acid test was used to reflect the risk of human exposure. A survey on COVID-19 related knowledge, attitude and behaviors were used to estimate the abilities of personal protection and emergency response.Results:The epidemic of COVID-19 in Shenzhen experienced the rising, plateau and decline stage. The case number increased rapidly at the beginning, with short duration of peak period. Although the epidemic curve showed human-to-human transmission, the "trailing" was not obvious. From the spot map, during the intervention period, the source of infection was widely distributed. More cases and higher transmission risk were observed in areas with higher population density. After the effective intervention measures, both infection sources and the risk of transmission decreased. After compared with the estimated case numbers without intervention, actual number proved the COVID-19 control strategies were effective. The positive rate of nucleic acid test for high risk populations decreased and no new cases reported since February 16. Shenzhen citizens had high knowledge, attitude and behavior level, and high protection ability and emergency response.Conclusions:Although the response initiated by the health administration department played a key role at the early stage of the epidemic, it was not enough to contain the outbreak of COVID-19. The first-level emergency response initiated by provincial and municipal government was effective and ensured the start of work resumption after the Spring Festival. Metropolitans like Shenzhen can also achieve the goals of strategies and measures for containment and mitigation of COVID-19.
