Teaching clinics represent a unique form of outpatient training of resident physicians and serve as a crucial instrument and core component of standardized training of general practice residents. This article reviews the common model and innovations of teaching clinics of general practice in China, and analyzes their reported effectiveness in enhancing the capabilities of consultation of resident physicians, the teaching capabilities of general practice trainers, as well as satisfaction levels of involved participants. It outlines the challenges encountered in implementing teaching clinics, including inadequate teaching facilities and equipment, incomplete incentive system for teaching, difficulties in patient recruitment, and weaknesses in the teaching capabilities of trainers. To address these challenges, this article proposes corresponding strategies based on realistic needs, including the improvement of facilities and equipment in teaching clinics, the establishment of incentive systems for teaching clinics, the expansion of patient recruitment channels for teaching clinics, and the enhancement of training for trainers' teaching capabilities. This is envisaged to provide both theoretical bases and practical guidance for the effective execution and standardized development of teaching clinics in general practice residency training bases.

Background::Limited information exists regarding the impact of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection on psoriasis patients. The objective of this study was to identify clinical factors associated with the prognosis of psoriasis following SARS-CoV-2 infection.Methods::A retrospective, multicenter study was conducted between March and May 2023. Univariable and multivariable logistic regression analyses were employed to identify factors associated with coronavirus disease 2019 (COVID-19)-related psoriasis outcomes. The study included 2371 psoriasis patients from 12 clinical centers, with 2049 of them having been infected with SARS-CoV-2.Results::Among the infected groups, lower exacerbation rates were observed in individuals treated with biologics compared to those receiving traditional systemic or nonsystemic treatments (22.3% [236/1058] vs. 39.8% [92/231] vs. 37.5% [140/373], P <0.001). Psoriasis progression with lesions (adjusted odds ratio [OR] = 8.197, 95% confidence interval [95% CI] = 5.685–11.820, compared to no lesions), hypertension (adjusted OR = 1.582, 95% CI = 1.068–2.343), traditional systemic (adjusted OR = 1.887, 95% CI= 1.263–2.818), and nonsystemic treatment (adjusted OR= 1.602, 95% CI= 1.117–2.297) were found to be associated with exacerbation of psoriasis after SARS-CoV-2 infection, but not biologics (adjusted OR = 0.931, 95% CI = 0.680–1.274, compared to no treatment), according to multivariable logistic regression analysis. Conclusions::A reduced risk of psoriasis exacerbation after SARS-CoV-2 infection was observed with biologics compared to traditional systemic and nonsystemic treatments. Significant risk factors for exacerbation after infection were identified as existing psoriatic lesions and hypertension.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the changing distribution and antibiotic resistance profiles of clinical isolates of Staphylococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Staphylococcus according to the unified protocol of CHINET(China Antimicrobial Surveillance Network)using disk diffusion method and commercial automated systems.The CHINET antimicrobial resistance surveillance data from 2015 to 2021 were interpreted according to the 2021 CLSI breakpoints and analyzed using WHONET 5.6.Results During the period from 2015 to 2021,a total of 204,771 nonduplicate strains of Staphylococcus were isolated,including 136,731(66.8％)strains of Staphylococcus aureus and 68,040(33.2％)strains of coagulase-negative Staphylococcus(CNS).The proportions of S.aureus isolates and CNS isolates did not show significant change.S.aureus strains were mainly isolated from respiratory specimens(38.9±5.1)％,wound,pus and secretions(33.6±4.2)％,and blood(11.9±1.5)％.The CNS strains were predominantly isolated from blood(73.6±4.2)％,cerebrospinal fluid(12.1±2.5)％,and pleural effusion and ascites(8.4±2.1)％.S.aureus strains were mainly isolated from the patients in ICU(17.0±7.3)％,outpatient and emergency(11.6±1.7)％,and department of surgery(11.2±0.9)％,whereas CNS strains were primarily isolated from the patients in ICU(32.2±9.7)％,outpatient and emergency(12.8±4.7)％,and department of internal medicine(11.2±1.9)％.The prevalence of methicillin-resistant strains was 32.9％in S.aureus(MRSA)and 74.1％in CNS(MRCNS).Over the 7-year period,the prevalence of MRSA decreased from 42.1％to 29.2％,and the prevalence of MRCNS decreased from 82.1％to 68.2％.MRSA showed higher resistance rates to all the antimicrobial agents tested except trimethoprim-sulfamethoxazole than methicillin-susceptible S.aureus(MSSA).Over the 7-year period,MRSA strains showed decreasing resistance rates to gentamicin,rifampicin,and levofloxacin,MRCNS showed decreasing resistance rates to gentamicin,erythromycin,rifampicin,and trimethoprim-sulfamethoxazole,but increasing resistance rate to levofloxacin.No vancomycin-resistant strains were detected.The prevalence of linezolid-resistant MRCNS increased from 0.2％to 2.3％over the 7-year period.Conclusions Staphylococcus remains the major pathogen among gram-positive bacteria.MRSA and MRCNS were still the principal antibiotic-resistant gram-positive bacteria.No S.aureus isolates were found resistant to vancomycin or linezolid,but linezolid-resistant strains have been detected in MRCNS isolates,which is an issue of concern.

Objective:To analyze the positioning error of vacuum pad and breast bracket in base note radiotherapy for breast cancer with breast conserving surgery based on cone beam CT (CBCT).Methods:A total of 120 patients who received IMRT after breast conserving surgery for breast cancer in the radiotherapy department of Nantong Cancer Hospital from April 2020 to April 2022 were retrospectively selected. According to the fixation method, the patients were divided into two groups: group A ( n=60) was fixed with a vacuum pad, and group B ( n=60) was fixed with a breast bracket. CBCT was used to evaluate the placement, and the placement errors and the occurrence of radiation dermatitis in each group were analyzed. Results:The translation errors of group A and group B in the left and right directions were (0.33±0.12)cm and (0.34±0.15)cm, respectively, and there was no statistically significant difference between the groups ( P>0.05). The errors in the direction of the abdomen and back were 0.32(0.11, 0.42)cm and 0.15(0.09, 0.21)cm, respectively, while the errors in the direction of the head and foot were 0.34(0.16, 0.34) cm and 0.23(0.15, 0.37)cm, respectively. The translation errors of the head, foot, and abdomen and back in group B were smaller than those in group A (all P<0.05). Patients in group B had significantly smaller translation errors in the left and right directions [group A: (0.31±0.13)cm, group B: (0.18±0.05)cm, P<0.05], and after rotation in the ventral and dorsal directions [group A: (0.31±0.11)cm, group B: (0.23±0.08)cm, P<0.05]. There was no statistically significant difference in translation errors after rotation in the head and foot directions ( P>0.05). The rotation error in the left and right directions of group B was smaller than that of group A [A: (0.98 0.12)°, group B: (0.67±0.31)°, P<0.05]. There was no statistically significant difference in the comparison of head foot and abdominal back rotation errors (all P>0.05). The planned center point (MIDM) of group B patients was located 10 cm to the left and right horizontally (MIDL, MIDR), with MIDM moving 8 cm to the head side (SM), MIDL moving 8 cm to the head side (SL), MIDR moving 8 cm to the head side (SR), MIDM moving 8 cm to the foot side (IM), MIDL moving 8 cm to the foot side (IL), and MIDR moving 8 cm to the foot side (IR). The thickness of the phantom was lower than that of group A (all P<0.05). At the completion of treatment, the total incidence of high-grade radiation dermatitis in group A was 61.67%(37/60), while the total incidence of high-grade radiation dermatitis in group B was 41.67%(25/60). The incidence of high-grade radiation dermatitis in group B was lower than that in group A ( P<0.05). Conclusions:Using breast bracket for breast fixation after breast conserving surgery for breast cancer can reduce the positioning error, the phantom thickness and the incidence of high-grade radiation dermatitis during intensity modulated radiotherapy, which is of high clinical value.

ObjectiveTo investigate the safety and efficacy of endoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips in the treatment of cirrhotic patients with gastric varices and gastric-renal shunt （GRS）. MethodsThe patients who attended Beijing Ditan Hospital， Capital Medical University， due to liver cirrhosis and gastric varices from February to June 2023 were enrolled， and all patients were confirmed to have GRS and received endoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips. The primary evaluation index was alleviation or disappearance of varicose veins after surgery， and the secondary evaluation indices were surgical completion and complications. ResultsA total of 11 patients were enrolled in this study， among whom there were 7 male patients and 4 female patients， with a median age of 55 years. Of all patients， 1 had Child class A liver function， 7 had Child class B liver function， and 3 had Child class C liver function. The maximum （median） diameter of the shunt was 8 mm， and the minimum （median） diameter of the shunt was 4 mm. The median blood flow velocity of the target vessel was 11 cm/s before treatment and 5 cm/s after occlusion with metal clips. The median amount of tissue adhesive injected was 2 mL， and the amount of lauromacrogol used was 1 mL. Disappearance of blood flow signals was observed in all patients after surgery （100%）， and the success rate of surgery was 100%. No patient experienced rebleeding after follow-up for 6 weeks. Gastroscopy at 1 month after surgery showed that gastric varices were eradicated or almost disappeared in 9 patients and were alleviated in 2 patients. ConclusionEndoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips is a feasible， safe， and effective treatment method for cirrhotic patients with gastric varices and GRS.

OBJECTIVES: To compare the clinical effect on Bell's facial palsy in the acute stage between the staging comprehensive treatment with acupuncture-moxibustion and western medication. METHODS: Sixty patients with Bell's facial palsy in the acute stage were randomly divided into an observation group and a control group, with 30 cases in each one. The patients in the control group were administered orally with prednisone acetate tablets and methylcobalamin tablets until the 28th day of illness. In the observation group, the staging comprehensive treatment with acupuncture-moxibustion was adopted. On the affected side, Qianzheng (EX-HN 16), Yifeng (TE 17), Sibai (ST 2), Yangbai (GB 14), Jiache (ST 6), Dicang (ST 4) and Touwei (ST 8), etc. were stimulated. In the acute stage (Day 1 to 7 of illness), the routine acupuncture and the point-toward-point needle insertion were delivered, no any manipulation was exerted at acupoints, and the needles were retained for 30 min. In the subacute stage (Day 8 to 14 of illness), on the base of the treatment as the acute stage, the depth of needle insertion was adjusted at a part of acupoints and the even needling technique was operated by twisting needle. Besides, electroacupuncture (EA) was attached to Qianzheng (EX-HN 16) and Dicang (ST 4), with continuous wave of low intensity and high frequency, 100 Hz, for 20 min. In the recovery stage (Day 15 to 28 of illness), on the base of the treatment as the subacute stage, the heavy stimulation of acupuncture was given, in which, the sticking and lifting needle techniques were delivered after the needles were inserted from Sibai (ST 2) toward Dicang (ST 4), and from Dicang (ST 4) toward Jiache (ST 6), separately; warm needling was operated at Yifeng (TE 17), and EA changed to stimulate the acupoints with the intermittent wave of high intensity and low frequency, 2 Hz, for 30 min. Acupuncture-moxibustion was given once every other day until the end of the 28th day of illness. The level of House-Brackmann facial nerve function rating scale (H-B grade),the score of Sunnybrook facial nerve grading system (Sunnybrook), the score of facial disability index (FDI), the temperature difference in the infrared thermal imaging facial area and electromyogram (EMG) situation of the affected muscle group were observed before and after treatment in the two groups. Using musculoskeletal ultrasound,the facial nerve diameter was detected and the clinical effect was compared between the two groups. RESULTS: After treatment, the level of H-B grade, Sunnybrook score, the scores of physical function and social life function in FDI were improved when compared with those before treatment in the patients of either group (P<0.01, P<0.05), and the results of these evaluations in the observation group were better than those of the control group (P<0.05). After treatment, the temperature difference of the frontal area, the eye area, the zygomatic area and the mouth corner was declined in comparison with that before treatment in the two groups (P<0.05), and the temperature difference in each area in the observation group was lower than that of the control group (P<0.05).The root mean square (RMS) of the frontal muscle group, the zygomatic muscle group and the orbicularis muscle group on the affected side increased in comparison with that before treatment in the two groups (P<0.01), and RMS of the observation group was higher than that of the control group (P<0.05) after treatment. Before treatment, the diameter of the facial nerve on the affected side was larger than that on the healthy side (P<0.01), and after treatment, the diameter on the affected side was reduced when compared with that before treatment in the two groups (P<0.01); the diameter of the facial nerve on the affected side in the observation group was smaller than that of the control group (P<0.05), while, the diameter on the affected side was larger when compared with the healthy side in the control group (P<0.05). The total effective rate of the observation group was 93.3% (28/30), higher than that of the control group (83.3% [25/30], P<0.05). CONCLUSIONS The staging comprehensive treatment with acupuncture-moxibustion is clearly effective on Bell's facial palsy in the acute stage, which affirms the effectiveness of acupuncture-moxibustion for the acute stage of Bell's facial palsy in comparison with conventional western medication.

OBJECTIVE To systematically evaluate the efficacy and safety of Shenfu injection combined with chemical medicine in the treatment of coronary heart disease combined with heart failure. METHODS Retrieved from CNKI， CBM， VIP， Wanfang， PubMed， Embase and the Cochrane Library， randomized controlled trials （RCTs） about Shenfu injection combined with chemical medicine （trial group） versus chemical medicine （control group） in the treatment of heart failure with coronary heart disease were collected during the inception to August 2022. After literature screening and data extraction， the qualities of included literature were evaluated and rated by using Cochrane manual and GRADE system. Meta-analysis and Egger’s were performed with RevMan 5.3 software， and TSA 0.9.5.10 Beta software was used for trial sequential analysis. RESULTS Seventeen studies were included， with a total sample of 1 355 patients. The quality grade evidence of GRADE was all low. Meta-analysis showed that cardiac function efficacy [RR＝1.23， 95%CI （1.16，1.30）， P＜0.000 01]， the decrease of brain natriuretic peptide [MD＝－96.06， 95%CI （－116.47， －75.64）， P＜0.000 01] and the increase of left ventricular ejection fraction [MD＝5.32， 95%CI （4.03，6.60）， P＜0.000 01] in trial group were significantly better than control group； there was no statistical significance in the incidence of ADR between 2 groups [RR＝0.52，95%CI（0.22，1.22），P＝0.13]. The results of sequential analysis showed that the sample size included in this study met the requirements of meta-analysis； the results of Egger’s test showed that the results were robust and publication bias had no significant effect on the results. CONCLUSIONS Shenfu injection combined with chemical medicine in the treatment of coronary heart disease combined with heart failure can further improve the clinical symptoms and related indicators， and no serious adverse reaction is observed.
