Chi-square test was performed to compared between counting data groups; Quantitative data were expressed by M ( Q1, Q3), and rank sum test was used for comparison between groups; Single factor survival analysis was performed by Kaplan-Meier method and Log rank test; Cox regression analysis were used for multivariate survival analysis. Results:①The male group had a higher proportion of rash at the sun exposure area [67.1%(47/70) vs 52.8%(93/176), χ2=4.18, P=0.041] and V-sign [50.0%(35/70) vs 30.7%(54/176), χ2=8.09, P=0.004] than the female group. The male group had higher levels of creatine kinase [112(18, 981)U/L vs 57 (13.6, 1 433)U/L, Z=-3.50, P<0.001] and ferritin [1 500 (166, 32 716)ng/ml vs 569 (18, 14 839)ng/ml, Z=-5.85, P<0.001] than the female group. The proportion of ILD [40.0%(28/70) vs 59.7%(105/176), χ2=7.82, P=0.020] patients and the red blood cell sedimentation rate[31.0(4.0, 101.5)mm/1 h vs 43.4(5.0, 126.5)mm/1 h, Z=-2.22, P=0.026] in the male group was lower than that of the female group, but the proportion of rapidly progressive interstitial lung disease (PR-ILD) [47.1%(33/70) vs 31.3%(55/176), χ2=5.51, P=0.019] was higher than that of the female group. ②In male patients with positive anti-MDA5 antibodies,the death group had a shorter course of disease[1.0(1.0, 3.0) month vs 2.5(0.5,84) month, Z=-3.07, P=0.002], the incidence of arthritis [16.7%(4/24) vs 42.2%(19/45), χ2=4.60, P=0.032] were low than those in survival group,while aspartate aminotransferase (AST)[64(22.1, 565)U/L vs 51(14,601)U/L, Z=-2.42, P=0.016], lactate dehydrogenase (LDH) [485(24,1 464)U/L vs 352(170, 1 213)U/L, Z=-3.38, P=0.001], C-reactive protein (CRP) [11.6(2.9, 61.7) mg/L vs 4.95(0.6, 86.4) mg/L, Z=-1.96, P=0.050], and ferritin levels [2 000(681, 7 676) vs 1 125 (166, 32 716)ng/ml, Z=-3.18, P=0.001] were higher than those in the survival group, and RP-ILD [95.8%(23/24) vs 22.2%(10/45), χ2=33.99, P<0.001] occurred at a significantly higher rate. ③Cox regression analysis indicated that the course of disease LDH level, and RP-ILD were related factors for the prognosis of male anti-MDA5 antibodies [ HR (95% CI)=0.203(0.077, 0.534), P=0.001; HR (95% CI)=1.002(1.001, 1.004), P=0.003; HR (95% CI)=95.674 (10.872, 841.904), P<0.001]. Conclusion:The clinical manifestations of male anti-MDA5 antibody-positive patients are different from those of female. The incidence of ILD is low, but the proportion of PR-ILD is high. The course of disease, serum LDH level, and RP-ILD are prognostic factors of male anti-MDA5 antibody-positive patients.

According to the characteristics of pain and disease process， postherpetic neuralgia （PHN） can be classified into the category of "collaterals disease" in traditional Chinese medicine. The key pathogenesis of PHN includes toxin， stasis and deficiency. The main syndromes of collaterals disease are pathogenic toxin burning collaterals， static blood blocking collaterals， and collaterals depletion. Ashi points are mainly selected for treatment of PHN. For the syndrome of pathogenic toxin burning collaterals， dense fire needling is suitable for removing toxin and relieving pain. For the syndrome of static blood blocking collaterals， collateral bloodletting is suitable to remove stasis and relieve pain. For the syndrome of collaterals depletion， the combination of encircling fire needling， hair needling and transverse insertion with filiform needles， and Jiaji acupoint （EX-B2） needling is suitable for nourishing collaterals and relieving pain. In clinical practice， the most appropriate acupuncture regimen can be selected according to the differentiated syndrome of "collaterals disease"， and with adoption of the holistic pattern differentiation and treatment， the clinical efficacy can be strengthened.

AIM: To explore the effect of lncRNA SNHG6 on injury of human retinal microvascular endothelial cells(hRMECs)induced by high glucose and its possible mechanism.METHODS: The D-glucose-induced hRMECs were used to establish normal glucose(NG)and high glucose(HG)cell injured model. In the HG group, the hRMECs were cultured in DMEM medium at a concentration of 25 mmol/L D-glucose for 24 h, while in the NC group, they were cultured in DMEM medium at a concentration of 5.5 mmol/L D-glucose; according to experimental design, si-NC, si-SNHG6, si-SNHG6 and anti-miR-NC and si-SNHG6 and anti-miR-186-5p were transfected into hRMECs, and then incubated at a concentration of 25 mmol/L D-glucose for 24 h, with HG+si-NC group, HG+si-SNHG6 group, HG+si-SNHG6+anti-miR-NC group and HG+si-SNHG6+anti-miR-186-5p group marked, respectively. The quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression of lncRNA SNHG6 and miR-186-5p; dual-luciferase reporter assay was used to detect the targeting relationship; MTT assay and flow cytometry were used to detect the cell proliferation and apoptosis, respectively; enzyme linked immunosorbent assay(ELISA)was used to detect the levels of IL-1β, TNF-α, IL-8, IL-10; testing kits were used to detect activity of SOD and level of MDA; the Western blot was used to detect the protein expression of cleaved-caspase3, Bax and Bcl-2.RESULTS: The lncRNA SNHG6 expression increased in the HG group, while miR-186-5p expression decreased(both P<0.05). There was target binding of lncRNA SNHG6 with miR-186-5p. After the transfection of si-SNHG6, cell inhibition rate, apoptosis rate, cleaved-caspase3, Bax protein levels, IL-1β, TNF-α, IL-8 contents, and MDA activity were decreased(P<0.05), while Bcl-2 protein, IL-10 contents, and SOD activity were increased(P<0.05). Co-transfection of si-SNHG6 and anti-miR-186-5p increased cell proliferation inhibition rate, apoptosis rate, cleaved-caspase3, Bax, IL-1β, TNF-α, IL-8, and MDA(P<0.05), but decreased Bcl-2, IL-10 and SOD(P<0.05).CONCLUSION: Interfering with lncRNA SNHG6 could inhibit cell apoptosis, inflammation and oxidative stress of high-glucose- induced hRMECs by elevating the expression of miR-186-5p.

Objective: To investigate the difference in influencing factors for diabetes between urban and rural residents in Hefei City, so as to provide the basis for control and research of diabetes. Methods: The residents aged 18 years and older were selected using the stratified multistage random sampling method from 5 districts (counties) in Hefei City from August to December 2021. Demographic information, smoking, self-rated health status and sleep duration were collected through questionnaire surveys. Height, body weight and fasting blood glucose were measured. The crude prevalence of diabetes was calculated and standardized by age using China Statistical Yearbook 2022. Factors affecting diabetes were identified using a multivariable logistic regression model. Results: Totally 10 443 residents were investigated, including 6 386 urban residents (61.15%) and 4 057 rural residents (38.85%). There were 4 690 males (44.91%) and 5 753 females (55.09%). Diabetes were detected in 1 492 cases, with a standardized prevalence of 9.57%. The standardized prevalence of diabetes among urban and rural residents were 9.21% and 12.58%, respectively, and the difference was statistically significant (P<0.05). Multivariable logistic regression analysis showed that region, age, educational level, occupation, body mass index and self-rated health status were influencing factors for diabetes. Further analysis stratified by urban and rural area showed that, in addition to the above factors, gender and smoking were influencing factors for diabetes among urban residents, while sleep duration was the influencing factor for diabetes among rural residents (all P<0.05). Conclusions There are urban-rural differences in the prevalence of diabetes among residents in Hefei City, and the prevalence of diabetes is associated with age, educational level, occupation, body mass index and self-rated health status.

ObjectiveTo explore the role of efficacy evaluation methods in providing evidence for traditional Chinese medicine （TCM） clinical practice guidelines based on a demonstration study of clinical efficacy evaluation of TCM for allergic rhinitis （AR），aiming to enrich the sources of evidence for guideline development. MethodReal-world data of TCM medication for AR were collected and efficacy evaluation was carried out. SPSS 16.0 software was used to calculate the conformity of clinical syndromes，main prescriptions， and medications to the guidelines. Correlation analysis of efficacy and medications was performed according to guideline conformity to compare the differences in medications between real-world clinical applications and current guidelines. ResultA total of 198 cases were collected and the clinical medications were compared with the relevant guidelines for AR. It was found that the clinical syndrome conformity was above 70%，and in addition to the guideline syndrome，there were also syndromes in six meridians and other mixed syndromes in clinical practice. The guideline conformity of the main prescriptions used in clinical practice showed a positive correlation trend with efficacy. There were some differences between the commonly used drugs in clinical practice and those recommended by the guidelines. For example，for lung Qi deficiency and cold syndrome，drugs such as Angelicae Dahuricae Radix， Magnoliae Flos， and Schisandrae Chinensis Fructus were often used. For kidney Yang deficiency syndrome，drugs such as Atractylodis Macrocephalae Rhizoma and Ostreae Concha were often used. For spleen Qi deficiency and weakness syndrome，drugs such as Poria， Cinnamomi Ramulus， and Magnoliae Flos were used. For lung Qi deficiency and cold syndrome in children，drugs such as Chebulae Fructus， Cicadae Periostracum， Zingiberis Rhizoma， and Ginseng Radix et Rhizoma were used. For lung and spleen Qi deficiency syndrome，drugs such as Dioscoreae Rhizoma， Menthae Haplocalycis Herba， Amomi Fructus， and Zingiberis Rhizoma were used. There were also some differences in the commonly used drugs for adults and children. For example，for lung Qi deficiency and cold syndrome，adults often used Angelicae Dahuricae Radix， Magnoliae Flos， and Tribuli Fructus，while children often used Ginseng Radix et Rhizoma， Paeoniae Radix Alba， and Poria. For lung meridian hidden heat syndrome， adults often used Bupleuri Radix， Asari Radix et Rhizoma， Pinelliae Rhizoma， and Xanthii Fructus， while children often used Houttuyniae Herba， Menthae Haplocalycis Herba， Citri Reticulatae Pericarpium， and Massa Medicata Fermentata. ConclusionEffective medication regimens can be screened out based on efficacy evaluation methods，which can help supplement immediate， objective， and clinically relevant evidence of medication for the development of clinical practice guidelines in TCM from the perspective of clinical effectiveness.

OBJECTIVE To discuss the application effect of health care failure mode and effect analysis(HFMEA) and root cause analysis(RCA) in the intelligent management of narcotic use in the hospital. METHODS Set up an analysis team to use HFMEA to list potential failure modes in the flow chart of intelligent management of narcotic use in the hospital, and analyze and evaluate the key failure modes in combination with RCA, determine the root cause, and then formulate improvement measures and evaluate the effects after implementation. RESULTS After the implementation of the improvement measures, the risk priority number of the eight potential failure modes decreased significantly(P<0.05). The satisfaction of pharmacists, doctors and nurses with the intelligent management process of narcotic use in the hospital increased from (88.39±2.21)% to (98.04±0.51)%, from (87.79±1.36)% to (97.55±1.24)%, and from (90.79±1.39)% to (95.68±1.30)%, respectively. CONCLUSION HFMEA combined with RCA can reduce the risk of narcotic drug abuse, ensure drug quality and safety, reduce the occurrence of dispensing errors, and ensure the rational clinical use of narcotic drugs.

Objective:To analyze the characteristics of adults (non-pregnant women) infected with Listeria monocytogenes and to provide evidence for diagnosis and treatment of this disease. Methods:Patients admitted in West China Hospital of Sichuan University between January 2008 and April 2020 with Listeriadisease were enrolled in this study. The clinical data of patients including age, symptoms, underlying diseases and prognosis, as well as the laboratory results of WBC, neutrophil ratio (N%), procalcitonin (PCT), interleukin-6 (IL-6) and C-reactive protein (CRP), were obtained for analyzing the clinical infection and prognosis characteristics of the patients. Results:A total of 57 patients were included, patients were 18-83 (52.8±15.9) years old, percent of over 60 years old patients accounted for 35.09% (20/57). The incidence rate in summer season was the highest (45.61%, 26/57). There were 48 cases with comorbidities, sepsis occurred in 31 cases and meningitis in 18 cases. The time of diagnosis of Listeriosis was (6.1±2.9) days. After diagnosis, the target therapy was applied: such as carbapenem (26.32%, 15/57) and penicillins (22.81%, 13/57). The levels of WBC (6.77 [2.99, 9.54]×10 9/L vs 10.23 [6.71, 16.55]×10 9/L), NLR (3.07 [1.66, 8.16] vs 11.26 [5.66, 20.08]) and CRP (40.7 [16.9, 91.9] g/L vs 92.8 [59.9, 142.7] g/L) were significantly lower after treatment than those before treatment in 47 hospitalized patients (all P<0.05). Thirty-eight patients were treated according to the guidelines, 33 cases improved, 2 cases had poor prognosis and 2 cases died. Conclusion:The main risk factors of Listeria monocytogenes infection in adults (non-pregnant women) are underlying diseases, especially autoimmune diseases and pulmonary infections. Penicillins can be used as the first choice for empirical therapy. Carbapenems and erythromycin serve as the combination medications during the full course of treatment.

BACKGROUND: Acquired immune deficiency syndrome (AIDS)-related non-Hodgkin lymphoma (AR-NHL) is a high-risk factor for morbidity and mortality in patients with AIDS. This study aimed to determine the prognostic factors associated with overall survival (OS) and to develop a prognostic nomogram incorporating computed tomography imaging features in patients with acquired immune deficiency syndrome-related non-Hodgkin lymphoma (AR-NHL). METHODS: A total of 121 AR-NHL patients between July 2012 and November 2019 were retrospectively reviewed. Clinical and radiological independent predictors of OS were confirmed using multivariable Cox analysis. A prognostic nomogram was constructed based on the above clinical and radiological factors and then provided optimum accuracy in predicting OS. The predictive accuracy of the nomogram was determined by Harrell C-statistic. Kaplan-Meier survival analysis was used to determine median OS. The prognostic value of adjuvant therapy was evaluated in different subgroups. RESULTS: In the multivariate Cox regression analysis, involvement of mediastinal or hilar lymph nodes, liver, necrosis in the lesions, the treatment with chemotherapy, and the CD4 ≤100 cells/μL were independent risk factors for poor OS (all P < 0.050). The predictive nomogram based on Cox regression has good discrimination (Harrell C-index = 0.716) and good calibration (Hosmer-Lemeshow test, P = 0.620) in high- and low-risk groups. Only patients in the high-risk group who received adjuvant chemotherapy had a significantly better survival outcome. CONCLUSION A survival-predicting nomogram was developed in this study, which was effective in assessing the survival outcomes of patients with AR-NHL. Notably, decision-making of chemotherapy regimens and more frequent follow-up should be considered in the high-risk group determined by this model.

Objective: To explore the influence of murine cytomegalovirus on phenotypic modulation of vascular smooth muscle cell and modulation of PI3K/Akt pathway. Methods: Male apoE knockout mice were injected abdominally with 2×10⁵ PFU MCMV, followed by 16 weeks feeding. Then aortas were sectioned for HE staining and immunohistochemical staining of smooth muscle 22 alpha (SM22α) and osteopontin (OPN). Mouse aortic smooth muscle cells(MOVAS)were incubated with MCMV, then proliferation of MOVAS and expression of SM22a and OPN were tested. Western blotting test was applied to reveal MCMV’s modulation of PI3K/Akt pathway. Results: The degree of atherosclerosis of apoE^-/- mice in MCMV infection group was severe than that in control group, and OPN stain positive signals predominated in the arterial wall. After 24 hours of incubation with MCMV by 3×10⁴ PFU, the expression of SM22a decreased (P=0.023), while OPN increased (P=0.034) in MOVAS. MCMV increased expression of Akt phosphorylation compared with the control group (P=0.035). The inhibitor of PI3K pathway LY294002 not only inhibited the phenotypic modulation of smooth muscle by MCMV, but also blocked the Akt phosphorylation after MCMV infection (P=0.031), however no significant influence was observed in control group. Conclusions MCMV induces phenotypic modulation of vascular smooth muscle, PI3K/Akt signaling pathway may be involved in the process of MCMV promoting the phenotype transformation of smooth muscle cells.
