OBJECTIVE:To provide data and reference for pharmacist legislation. METHODS:Questionnaire survey was de-signed investigate and analyze the staffing situation,education level,professional composition,age composition,professional titles composition,continuing education and wage of pharmacists who worked in medical and health institutions from 16 states (cities) in Yunnan province,and suggestions were put forward for relevant legislation. RESULTS:Totally 10 questionnaires were received from provincial medical and health institutions,and 16 from state (city) Health and Family Planning Commission,with effective recovery of 100%;data covered 1 561 medical and health institutions,involving 7 409 pharmacists. The numbers of pharmacy per-sonnel/hospital beds in tertiary hospitals,secondary hospitals and class-1 hospitals were 1∶15.49,1∶17.50,1∶20.68,numbers of pharmacy personnel/health professional and technical personnel in hospital accounted for 5.62%,6.18%,5.30%,respectively;most pharmacists in tertiary hospitals were mainly undergraduate degree(35.21%),doctor degree accounted for 0.15%,the high-est ratio of education was junior college degree in secondary hospitals(41.60%)and class-1 hospitals(57.51%);most pharmacists graduated in pharmacy in tertiary hospitals(94.14%),70.22% in secondary hospitals and only 10.50% in class-1 hospitals;phar-macy personnel mainly held the pharmacist professional titles in tertiary,secondary and class-1 hospitals (33.83%,37.89% and 63.55%),senior professional titles accounted for 5.88%,2.71% and 0.21%,respectively;only a few have learning experience and almost less than 6 months (9.17%,5.84% and 21.32%),and 80 pharmacists were certificated as clinical pharmacists in the whole province;generally,all wage was concentrated in 2 000-2 999 per month (27.72%,41.80% and 55.90%,respectively). CONCLUSIONS:Shortage of hospital pharmacists and lack of senior personnel are the main problems in Yunnan province,and wage is not high,especially in primary hospital,this situation is more obvious. The current situation of pharmacists in the hospital should be more taken into consideration during the legislative process in aspects of clearing and guaranteeing access qualifications, responsibilities,status,rights and interests,and pharmaceutical technology and service charges should be established.

Objective To investigate the clinical characteristics of the human Adenovirus (HAdv) infections in allogeneic hematopoietic stem cell transplantation ( allo-HSCT) patients and explore the clinical significance of HAdv monitoring .Methods A total of 845 cases underwent allo-HSCT were included retrospectively in Perking University People′s Hospital from October 2012 to August 2014.Peripheral blood HAdv load were monitored twice weekly within 100 days after allo-HSCT, or whenever necessary quantitatively by real-time PCR. Meanwhile, other clinical samples such as stool , urine, and bronchoalveolar lavage fluid ( BLAF ) were also detected qualitatively whenever necessary .The follow-up period was at least six months after allo-HSCT.All clinical data were collected and analyzed .Results The total positive rate of HAdv was 3.4% ( 29/845 ) .The incidence of HAdv infection was higher in children [3.8%(6/155), <18y] than that of adults [3.3%(23/690),≥18y].HAdv infection diagnosed within 100 days after allo-HSCT accounted for 72.4%(21/29) of the total number of positive cases .There were 19 cases detected positive in peripheral blood , 16 cases in stool , 9 cases in urine , and 1 cases in BLAF , respectively.One patient was positive in peripheral blood , stool and urine.The overall median time of HAdv was 69 (13-189) d.The median time was 56 (53 -144) d in stool ,which was earlier than that of in peripheral blood , urine and stool.Among 29 cases of HAdv positive patients , 17 patients were coinfected with Cytomegalovirus(CMV) and 11 casess with Epstein-Barr virus(EBV).Twenty-five cases of HAdv were diagnosed with acute graft-versus-host disease(aGVHD) before HAdv infection, and 4 cases were diagnosed with chronic graft-versus-host disease ( cGVHD ) . The most common clinical manifestation was HAdv enteritis (14 cases), followed by hemorrhagic cystitis (7 cases).Two cases complicated with multiple organ injury ( >2 ) clinically, 1 cases with pneumonia.There were 8 cases of death at the end of follow-up.Conclusions HAdv is an important pathogen causing infection in patients after allo-HSCT. The infenction is characterized with multiple organ involvement .CMV and EBV coinfection is common .HAdv monitoring was of great significance in allo-HSCT patients.

ObjectiveTo observe the clinical efficacy of Qushi Huayu granules in treating non-alcoholic fatty liver disease （NAFLD） with dampness-heat accumulation. MethodSixty NAFLD patients with the syndrome of dampness-heat accumulation treated in the outpatient and inpatient departments of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine from July 2018 to May 2020 were selected according to the diagnostic criteria and inclusion criteria of both traditional Chinese medicine （TCM） and Western medicine. The patients were assigned into a control group and an observation group by a random， controlled， double-blind， and double simulated method. The observation group was treated with Qushi Huayu granules combined with the mimetic agent of Dangfei Liganning capsules， and the control group was treated with Dangfei Liganning capsules combined with the mimetic agent of Qushi Huayu granules. The treatment course of both groups was 24 weeks. The TCM symptom scores， liver imaging parameters ［controlled attenuation parameter （CAP） in Fibroscan and liver-to-spleen ratio in upper abdominal computerized tomography （CT）］， serum levels of alanine aminotransferase （ALT） and γ-glutamyl transpeptidase （γ-GT）， and safety indicators of the two groups were measured. Result① The total response rate in terms of TCM symptoms in the observation group was 89.29% （25/28）， which was higher than that （48.15%， 13/27） in the control group （Z=-3.582，P<0.01）. The total score of the primary and secondary symptoms in both groups of patients declined after treatment （P<0.05）， and the observation group outperformed the control group in decreasing the total score of the main and secondary symptoms as well as the scores of right rib swelling pain， abdominal fullness and distension or pain， sticky stool， and yellow urine （P<0.05）. ② The response rate in terms of Fibroscan CAP of the liver in the observation group was 75.00% （21/28）， which was higher than that （48.15%， 13/27） in the control group （Z=-1.968，P<0.05）. ③ The response rate in terms of the serum enzyme levels in the observation group was 75.00% （21/28）， which was higher than that （44.44%， 12/27） in the control group （Z=-2.018，P<0.05）. The serum levels of ALT and γ-GT in the two groups declined after treatment （P<0.05， P<0.01） and were lower in the observation group than in the control group （P<0.05， P<0.01）. ④ The response rate in terms of liver CT in the observation group was 67.86% （19/28）， which was higher than that （30.77%，8/26） in the control group （Z=-2.507，P<0.05）. ConclusionQushi Huayu granules were safe and effective in the clinical treatment of NAFLD patients with the syndrome of dampness-heat accumulation， which improved the evidence in TCM treatment of NAFLD and was worthy of in-depth clinical research and promotion. Qushi Huayu granules outperformed Dangfei Liganning capsules in terms of TCM symptoms， serum levels of ALT and γ-GT， and liver imaging parameters.

OBJECTIVE： To observe improvement effects of fingolimod on middle cerebral artery occlusion/reperfusion （MCAO/R） injury model rats. METHODS： Male SD rats were randomly divided into sham operation group， model group and fingolimod low-dose， medium-dose and high-dose groups （0.5， 1， 2 mg/kg）， with 8 rats in each group. Except for sham operation group， MCAO/R injury model was induced by suture-occluded method in other groups. Administration groups were given relevant medicine intragastrically after reperfusion [1 h after reperfusion （1st day）， 22.5 h after reperfusion （2nd day）， and then every 24 h until 142.5 h of reperfusion （7th day）]. Sham operation group and model group were given constant volume of normal saline intragastrically， once a day， for consecutive 7 d. The scores of neurological deficit and balance beam test， the times of memory error [work memory error （WME）， reference memory error （RME） and total error] were recorded in each group. The contents of serum inflammatory cytokines （IL-6， IL-8， IL-10， TNF-α） were determined by ELISA， and triphenyl tetrazolium chloride staining method was used to detect the rate of cerebral infarction. RESULTS： Compared with sham operation group， neurological deficit scores （at different time points of 1st-7th day after administration）， balance beam test scores （2nd， 4th， 7th day after administration）， times of memory error （2nd， 4th， 7th day after administration）， the contents of serum inflammatory cytokines and the rate of cerebral infarction were increased significantly in model group （P＜0.05 or P＜0.01）. Compared with model group， neurological deficit scores （low-dose group at different time points of 3rd-7th day， medium-dose and high-dose groups at different time points of 2nd-7th day after administration）， balance beam test scores （low-dose group at 7th day， medium-dose group at 4th and 7th day， high-dose group at 2nd， 4th， 7th day）， RME times and total error times （low-dose group at 4th and 7th day， medium-dose group and high-dose group at 2nd， 4th， 7th day after administration）， WME times （administrations groups at 7th day after administration）， serum contents of IL-6， IL-8 and IL-10 （administrations groups）， serum contents of TNF-α （medium-dose and high-does groups） and cerebral infarction rate （medium-dose and high-dose groups） were all decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS： Intragastric administration of fingolimod can significantly reduce neurological deficit score， balance beam test score and the times of memory error in MCAO/R injury model rats， and has a protective effect on cerebral tissue and memory function. These effects may be related to the down-regulation of inflammatory cytokines such as IL-6 and TNF-α by fingolimod.

Mouse cortical radial glial cells (RGCs) are primary neural stem cells that give rise to cortical oligodendrocytes, astrocytes, and olfactory bulb (OB) GABAergic interneurons in late embryogenesis. There are fundamental gaps in understanding how these diverse cell subtypes are generated. Here, by combining single-cell RNA-Seq with intersectional lineage analyses, we show that beginning at around E16.5, neocortical RGCs start to generate ASCL1
