In order to make the shared traditional Chinese medicine （TCM） pharmacy develop more efficiently and normatively at the grass-roots level， using the “shared TCM pharmacy” as the retrieval word， this paper uses the literature research method to retrieve the reports， documents and policies from CNKI， the websites of people’s governments at all levels， the official websites of the State Administration of Traditional Chinese Medicine， people.com， China News Network， Xinhua News and other platforms before May 20， 2022， sort out the development mode and history of two “Internet plus” TCM pharmacies， namely “shared TCM pharmacies” and “smart TCM pharmacies”， and compare them with each other. Combined with the actual work of community hospitals and community service centers （stations）， the necessity and advantages （such as reducing the costs of the intermediate links of drug circulation and standardizing the grass-roots drug use process） of the development of “shared TCM pharmacy” are obtained from the perspective of primary medical care. Combined with the current situation of the promotion and application of shared TCM pharmacy in county medical communities， it is concluded that the shared TCM pharmacy should be further constructed from four aspects： improving the work process of drug centralized procurement under the background of normalization， improving the compatibility and synchronization of the whole process dispensing information system module， unifying pharmaceutical services and personnel training， defining the authority of data query and clarifying the boundaries of patient privacy to further build a shared TCM pharmacy. Finally， it integrates information technology， summarizes the definition of shared TCM pharmacy and its future construction direction， and provides reference for the next development of shared TCM pharmacy at the grass-roots level.

Objective: To explore the characteristics of viral infections in children with diarrhea in Beijing from 2018 to 2022. Methods: Real-time PCR and enzyme-linked immunosorbent assay were used to detect viral nucleic acid of Norovirus (NoV), Sappovirus (SaV), Astrovirus (AstV), Enteric Adenovirus (AdV) or antigen of Rotavirus (RV) in 748 stool samples collected from Beijing Capital Institute of Pediatrics from January 2018 to December 2021. Subsequently, the reverse transcription PCR or PCR method was used to amplify the target gene of the positive samples after the initial screening, followed by sequencing, genotyping and evolution analysis, so as to obtain the characteristics of these viruses. Phylogenetic analysis was performed using Mega 6.0. Results: From 2018 to 2021, the overall detection rate of the above five common viruses was 37.6%(281/748)in children under 5 years old in Beijing. NoV, Enteric AdV and RV were still the top three diarrhea-related viruses, followed by AstV and SaV, accounting for 41.6%, 29.2%, 27.8%, 8.9% and 7.5%, respectively. The detection rate of co-infections with two or three diarrhea-related viruses was 4.7% (35/748). From the perspective of annual distribution, the detection rate of Enteric AdV was the highest in 2021, while NoV was predominant in the other 4 years. From the perspective of genetic characteristics, NoV was predominant by GⅡ.4, and after the first detection of GⅡ.4[P16] in 2020, it occupied the first two gene groups together with GⅡ.4[P31]. Although the predominant RV was G9P[8], the rare epidemic strain G8P[8] was first detected in 2021. The predominant genotypes of Enteric AdV and AstV were Ad41 and HAstV-1. SaV was sporadic spread with a low detection rate. Conclusion: Among the diarrhea-related viruses infected children under 5 years of age in Beijing, the predominant strains of NoV and RV have changed and new sub-genotypes have been detected for the first time, while the predominant strains of AstV and Enteric AdV are relatively stable.

Aim To clarify the effect of circulating exosomes on hypertension, screen out miRNAs which plays a key role, and explore its function.Methods The plasma exosomes of spontaneously hypertensive rats were extracted and injected into Sprague Dawley rats.The blood pressure changes of rats were detected.Plasma exosomes and exosomal RNA of hypertensive patients and SHR were extracted.Real time PCR was used to verify the expression changes of the selected 8 miRNAs; Western blot was used to detect the expression changes of LKB1 and PTEN protein levels in human umbilical vein endothelial cells transfected with miR-17-5p mimics.Results The plasma exosomes of SHRs significantly increased the blood pressure of SD rats(P<0.05).The expression of miR-17-5p and miR-218-5p in the plasma exosomes of hypertensive patients and SHRs both significantly increased.miR-17-5p inhibitors significantly attenuated the effect of SHR-exos on raising blood pressure.miR-17-5p mimics down-regulated the expression of LKB1 and PTEN in HUVECs cultured in vitro.Conclusions The plasma exosomes of SHR can significantly increase blood pressure of Sprague Dawley rats.miR-17-5p may be the key miRNA.exo-miR-17-5p may promote the occurrence and development of hypertension by regulating the LKB1/PTEN signal.

Objective To establish the quality standard of Gansu granules (GGs) and effectively control the quality of GGs. Methods TLC identification method of Gansu granules was improved by using pinocembrin-7-O-β-D-glucoside as the indicator. In HPLC analysis, Agilent ZorbaxSB-C₁₈ (4.6 mm×250 mm, 5 μ m) was used as a chromatographic column, and acetonitrile-0.5% formic acid solution was used as the mobile phase. The detection wavelength of 280 nm was used to analyze the content of pinocembrin-7-O-β-D-glucoside in GGs. Results The separation of characteristic spots was good and clear when the established TLC method was used to identify Gansu granules. Quantitative analysis showed that the concentration of pinocembrin-7-O-β-D-glucoside has a good linear relationship with the peak area in the range of 2.4-240 µg/ml (r= 0.9999). The average sample recovery rate of pinocembrin-7-O-β-D-glucoside is 100.76% with RSD value of 0.66%. The accuracy was good. Conclusion The TLC identification method and HPLC content determination method established in this experiment have strong specificity and good reproducibility, and can be used as an improved standard for the quality control of Gansu granules.

OBJECTIVE: To observe the effect of electroacupuncture (EA) at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) on mental state, visceral sensitivity and protein expression of nerve growth factor (NGF), tyrosine kinase receptor A (TrkA) and transient receptor potential vanilloid 1 (TRPV1) of colonic tissue in diarrhea-predominant irritable bowel syndrome (IBS-D) rats, and to explore its possible mechanism on treating IBS-D. METHODS: A total of 36 male SD rats of SPF grade were randomized into a blank group, a model group, an EA group and a western medication group, 9 rats in each group. In the model group, the EA group and the western medication group, IBS-D model was established by enema of dinitrobenzene sulfonic acid (DNBS) combined with chronic restraint stress method. In the EA group, EA was applied at "Tianshu" (ST 25) and "Shangjuxu" (ST 37), with disperse-dense wave, in frequency of 2 Hz/100 Hz, 20 min each time, once a day for 7 days. In the western medication group, pinaverium bromide suspension was given by gavage (15 mg•kg^-1•d^-1) for 7 days. Before and after model establishment, and after intervention, the body mass, 24 h food intake and fecal water content were observed, the visceral sensitivity was detected by abdominal withdrawal reflex (AWR); after intervention, the mental state was evaluated by elevated plus maze (EPM) test, the protein expression of NGF, TrkA and TRPV1 was detected by immunohistochemistry and Western blot in the 4 groups. RESULTS: After model establishment, compared with the blank group, the body mass and 24 h food intake were decreased (P<0.05), first systolic latency of AWR was shortened and number of contraction wave of AWR was increased (P<0.05), and fecal water content was increased (P<0.05) in the model group, the EA group and the western medication group. After intervention, compared with the blank group, open arm residence time ratio (OT%) of EPM was decreased (P<0.05) and protein expression of NGF, TrkA, TRPV1 in colonic tissue was increased in the model group (P<0.05); compared with the model group, the body mass and 24 h food intake were increased (P<0.05), first systolic latency of AWR was lengthened and number of contraction wave of AWR was decreased (P<0.05), the fecal water content was decreased (P<0.05), OT% of EPM was increased (P<0.05), and protein expression of NGF, TrkA, TRPV1 in colonic tissue was decreased (P<0.05) in the EA group and the western medication group. CONCLUSION Electroacupuncture at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) can relieve the anxiety and depression-like behaviors in IBS-D rats, down-regulate the protein expression of NGF, TrkA, TRPV1 in colonic tissue, so as to reduce the visceral sensitivity and relieve symptoms.

Objective: This study sought to investigate the impact of different obesity patterns on coronary microvascular function in male patients with non-obstructive coronary artery disease. Methods: We retrospectively analyzed clinical data of male patients diagnosed with suspected coronary microvascular dysfunction (CMD) in the First Hospital of Shanxi Medical University between December 2015 and August 2021. All patients underwent the one-day rest and stress ¹³N-ammonia positron emission tomography myocardial perfusion imaging. Overall obesity was defined by body mass index (BMI) ≥28 kg/m² and abdominal obesity was defined by waist circumference ≥90 cm. Hyperemic myocardial blood flow (MBF)<2.3 ml·min^-1·g^-1 or coronary flow reserve (CFR)<2.5 were referred as CMD. All patients were grouped based on their BMI and waist circumference. MBF, CFR, the incidence of CMD, hemodynamic parameters, and cardiac function were compared among the groups. Results: A total of 136 patients were included. According to BMI and waist circumference, patients were categorized into 3 groups: control group (n=45), simple abdominal obesity group (n=53) and compound obesity group (n=38). Resting MBF did not differ between groups (F=0.02,P=0.994). Compared with the control group, hyperemic MBF was significantly lower in the simple abdominal obesity and compound obesity groups ((2.82±0.64) ml·min^-1·g^-1, (2.44±0.85) ml·min^-1·g^-1 and (2.49±0.71) ml·min^-1·g^-1, both P<0.05, respectively). Hyperemic MBF was comparable among the groups of patients with obesity (P=0.772). CFR was significantly lower in the simle abdominal obesity group compared with the control group (2.87±0.99 vs. 3.32±0.62,P=0.012). Compared with the control group, CFR tended to be lower in the compound obesity group (3.02±0.91 vs. 3.32±0.62,P=0.117). The incidence of CMD was significantly higher in both the simple abdominal obesity and compound obesity groups than in the control group (62.3%, 52.6% vs. 22.2%, both P<0.01, respectively). Waist circumference was an independent risk factor for male CMD (OR=1.057, 95%CI: 1.013-1.103, P=0.011). Conclusions: In male patients with non-obstructive coronary artery disease, abdominal obesity is associated with decreased coronary microvascular function. Male patients with simple abdominal obesity face the highest risk of CMD.

Objective: To investigate the safety, feasibility and short-term efficacy of total laparoscopic loop ileostomy reversal in patients after resection of rectal cancer. Methods: The clinical data of 20 patients who underwent total laparoscopic loop ileoscopic loop ileostomy after radical resection of rectal cancer at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, or Beijing Chaoyang District Sanhuan Cancer Hospital from October 2019 to June 2020 were collected and retrospectively analyzed. Results: All patients had successfully underwent total laparoscopic ileostomy reversal without conversion to open surgery or discontinued operation. No perioperative related death cases were found. In the whole group, the median operation time was 97 (60-145) minutes and the median intraoperative blood loss was 20 (10-100) milliliters. The median Visual Analogue Scale (VAS) score was 1.9 (1-5) one day after the operation. Nobody needed to use additional analgesic drugs. The median time to grand activities was 25 (16-42) hours, the median time to flatus was 44 (19-51) hours, and the median hospitalization after operation was 6.9 (5-9) days. No patients underwent operation related complications such as operative incision infection, abdominal and pelvic infection, intestinal obstruction, anastomotic leakage, bleeding and so on. Conclusions: Total laparoscopic loop ileostomy reversal appears to be safe, feasible and with promising efficacy for selected patients.

Objective:To evaluate the efficacy of remimazolam combined with low-dose propofol for sedation during induction of anesthesia.Methods:A total of 228 patients of both sexes, aged 18-64 yr, with body mass index of 19-35 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic cholecystectomy, were divided into 2 groups ( n=114 each) by a random number table method: remimazolam combined with low-dose propofol group (group R) and propofol group (group P). Anesthesia was induced with intravenous injection of sufentanil 0.3 μg/kg, remimazolam 0.3 mg/kg, propofol 0.5 mg/kg and micuronium 0.2 mg/kg in group R, and sufentanil 0.3 μg/kg, propofol 2 mg/kg and micuronium 0.2 mg/kg in group P. Endotracheal intubation was performed when bispectral index value ≤ 50.Before induction (T 0), immediately before intubation (T 1), at 1 min (T 2) and 3 min (T 3) after intubation, mean arterial pressure (MAP) and heart rate (HR) were recorded.The anesthesia induction time and the incidence of hypotension and bradycardia were recorded in the two groups. Results:There was no significant difference in MAP and HR at T 0 between the two groups ( P>0.05). Compared with the value at T 0, MAP in two groups and HR were significantly decreased at T 1-3 in group P ( P<0.01). Compared with group P, the anesthesia induction time was significantly prolonged, and hypotension and bradycardia was decreased in group R ( P<0.05). Conclusion:The combination of remimazolam and low-dose propofol exerts better efficacy for sedation during induction of anesthesia than propofol alone.
