Objective: To investigate the treatment outcomes and influencing factors among elderly patients with pulmonary tuberculosis in Lishui City, Zhejiang Province, so as to provide a basis for optimizing the prevention and control strategies of pulmonary tuberculosis and reducing the risk of adverse treatment outcomes among elderly patients. Methods: Data on patients aged ≥60 years with pulmonary tuberculosis in Lishui City from 2016 to 2022 were collected from the Tuberculosis Information Management System of the China Disease Prevention and Control Information System, including basic information, diagnosis and treatment details, and laboratory test results. The successful treatment rate and the incidence of adverse treatment outcomes were calculated. Factors affecting adverse treatment outcomes among elderly patients with pulmonary tuberculosis were analyzed using multivariable logistic regression model. Results: A total of 3 094 elderly patients with pulmonary tuberculosis were registered in Lishui City from 2016 to 2022, with a median age of 70 (interquartile range, 13) years. There were 2 396 male patients (77.44%) and 698 female patients (22.56%). A total of 2 676 patients achieved successful treatment, with a successful treatment rate of 86.49%. The successful treatment rate demonstrated a significant upward trend from 2016 to 2022 (P<0.05). There were 418 patients with adverse treatment outcomes, accounting for an incidence of 13.51%. The main types of adverse outcomes were death and loss to follow-up, with 199 and 100 patients, accounting for 47.61% and 23.92%, respectively. Multivariable logistic regression analysis showed that elderly patients with pulmonary tuberculosis who were male (OR=1.333, 95%CI: 1.018-1.745), aged ≥70 years (70-<80 years, OR=1.909, 95%CI: 1.469-2.481; ≥80 years, OR=3.878, 95%CI: 2.967-5.068), living in rural areas (OR=1.332, 95%CI: 1.068-1.661), with positive etiological results (OR=1.470, 95%CI: 1.143-1.889), and undergoing retreatment (OR=1.923, 95%CI: 1.419-2.607) had a higher risk of adverse treatment outcomes. Conclusions The successful treatment rate showed an upward trend among elderly patients with pulmonary tuberculosis in Lishui City from 2016 to 2022. Gender, age, place of residence, etiological results, and treatment type were influencing factors for adverse treatment outcomes among elderly patients with pulmonary tuberculosis.

Objective To observe the clinical efficacy of traditional Chinese medicine(TCM)sequential therapy in treating patients with psoriasis vulgaris in Shenzhen,and to explore the syndrome differentiation and treatment for the patients with psoriasis vulgaris in Shenzhen region.Methods From January 2019 to February 2024,70 cases of psoriasis vulgaris admitted to Shenzhen Bao'an Traditional Chinese Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine(Shenzhen Bao'an Traditional Chinese Medicine Hospital Group)were retrospectively analyzed.The patients were divided into the observation group(39 cases)and the control group(31 cases)according to the treatment plans.In the control group,only topical application of Calcipotriol Ointment was given throughout the treatment,while in the observation group the patients were treated with TCM sequential therapy according to the illness stage on the basis of treatment for the control group,i.e.,internal administration of modified Shuiniujiao Huanglian Decoction was given in the acute stage and modified Sijunzi Shuiniujiao Decoction was given in the remission stage.Both groups were treated for 3 months.Before and after the treatment,the changes of Psoriasis Area and Severity Index(PASI)scores,Dermatology Life Quality Index(DLQI)scores and TCM syndrome scores in the two groups were observed.After treatment,the clinical efficacy and drug safety of the two groups were evaluated.Results(1)After 3 months of treatment,the total effective rate of the observation group was 89.74%(35/39),and that of the control group was 74.19%(23/31).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the PASI scores for evaluating the severity of skin lesions in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the DLQI scores for evaluating the quality of life in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the scores of TCM syndromes such as erythema,itching,vexation and dry mouth in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(5)During the treatment period,no obvious adverse reactions occurred in the two groups of patients,with high safety.Conclusion On the basis of conventional western medicine treatment,application of TCM sequential therapy exerts certain clinical efficacy in treating patients with psoriasis vulgaris in Shenzhen region,and the combined therapy is effective on controlling the patients'illness conditions,significantly alleviating the symptoms and improving the quality of life of the patients.

Fresh Chinese herbal medicine,being distinct from the dried herbs,is one of the therapies of traditional Chinese medicine(TCM)widely used in dermatology.It is employed to treat various skin diseases,namely herpes simplex,herpes zoster,common warts,flat warts,boils,carbuncles,erysipelas,acne vulgaris,fungal skin diseases,psoriasis,contact dermatitis,insect bite dermatitis,and eczema.The commonly-used fresh herbs for skin diseases are fresh Portulacae Herba,fresh Houttuyniae Herba,fresh Rubiae Radix,fresh Lygodii Spora,fresh Patriniae Herba,fresh Aloe,fresh Plataginis Herba,fresh Pinelliae Rhizoma,and fresh Taraxaci Herba.These herbs usually have the actions of clearing heat,detoxifying,and cooling blood.For the treatment of skin diseases,fresh herbal medicine can be administered orally or applied topically,with a predominant use of topical application or a combination of oral and topical administration.Due to the rapid development of modern society,the supply and standardization of fresh herbs fail in meeting the demands of a large population of the patients,leading to their gradual decline in use.However,the efficacy of fresh herbs cannot be entirely replaced by that of the dried herbs.This article reviewed the advances in the modern application of fresh Chinese herbal medicine in dermatology,aiming to promote further research and expand its clinical application in treating skin diseases.

Objective: To investigate the status of regular HIV testing and post exposure prophylaxis (PEP) behaviors among men who have sex with men (MSM) in Lishui City, Zhejiang Province, so as to provide the reference for developing targeted intervention strategies. Methods: A total of 389 MSM were selected from Lishui City by convenient sampling method from April to August 2022, and demographic information, sexual behaviors, HIV testing and PEP behaviors were collected through questionnaire surveys. MSM were clustered using two step clustering analysis, and regular HIV testing and PEP behaviors among different groups of MSM were compared. Factors affecting regular HIV testing and PEP behaviors were evaluated using a multivariable logistic regression model. Results: The MSM surveyed had a median age of 31.00 (interquartile range, 16.00) years. There were 146 MSM undergoing regular HIV testing, accounting for 37.53%, and 47 MSM receiving PEP, accounting for 12.08%. MSM were divided into two groups. There were 28.05% of MSM with regular HIV testing in group 1, which was lower than the 44.44% in group 2; and 22.56% receiving PEP, which was higher than the 4.44% in group 2 (both P<0.05). Multivariable logistic regression analysis identified age (OR=1.030, 95%CI: 1.011-1.050), sexual roles (both receptive and insertive, OR=2.999, 95%CI: 1.732-5.194) and homosexual behaviors in the past 6 months (use condoms every time, OR=4.567, 95%CI: 2.593-8.044) as factors affecting regular HIV testing among MSM; age (OR=0.970, 95%CI: 0.942-0.999), sexual orientation (OR=0.292, 95%CI: 0.139-0.612) and homosexual behaviors in the past 6 months (not use condoms, OR=0.135, 95%CI: 0.040-0.460; use condoms every time, OR=0.076, 95%CI: 0.018-0.326) as factors affecting PEP behaviors among MSM. Conclusion MSM with different characteristics of sexual behaviors have different preferences for HIV regular testing and PEP, with homosexual behaviors in the past 6 months, sexual roles and sexual orientation being the main influencing factors.

ObjectiveTo explore the effectiveness and safety of vibration-kneading abdominal tuina as an adjunct treatment for insomnia of phlegm-heat harassing the interior syndrome with "stomach disharmony" symptom. MethodsSeventy-six insomnia patients of phlegm-heat harassing the interior syndrome with "stomach disharmony" symptom were recruited， and randomly divided into the treatment group and the control group with 38 cases in each group. The control group received eszopiclone 2mg once a night and sleep hygiene guidance， while the treatment group received vibration-kneading abdominal tuina additionally， 5 times a week， 30 min each time. Both groups were treated for 4 weeks. The Pittsburgh Sleep Quality Index （PSQI） （including sleep quality， time to fall asleep， sleep duration， sleep efficiency， sleep disorders， daytime functioning scores， and total scores） and traditional Chinese medicine （TCM） symptom scores of "stomach disharmony" was assessed before and after 4-week treatment and at follow-up （12 weeks after treatment）. Adverse events were also observed and recorded during the study. Pearson correlation analysis was used to assess the correlation between the pre-treatment PQSI total score and TCM symptom score of "stomach disharmony". ResultsThe PSQI scores of sleep quality， time to fall asleep， sleep duration， sleep efficiency， sleep disorders， daytime dysfunction scores， and total scores reduced in both groups decreased after treatment and at follow-up （P＜0.05 or P＜0.01）， as well as the TCM symptom score of "stomach disharmony" （P＜0.01）. After treatment， the PSQI scores of sleep quality， sleep duration， and TCM symptom score of "stomach disharmony" of the treatment group were lower than those of the control group （P＜0.05 or P＜0.01）. At follow-up， the PSQI scores of sleep quality， sleep duration， sleep efficiency， daytime dysfunction score， total score， and TCM symptom score of "stomach disharmony" of the treatment group were lower than those of the control group （P＜0.05 or P＜0.01）. No adverse reactions occurred in any participants during the study. There was a positive correlation between the patients' pre-treatment PQSI total scores and TCM symptom score of "stomach disharmony" （r=0.88， P＜0.01）. ConclusionVibration-kneading abdominal tuina as an adjunct treatment could significantly improve the symptoms of stomach and epigastric symptoms in insomnia patients of phlegm-heat harassing the interior syndrome with "stomach disharmony" symptom， and improve the quality of sleep， with good immediate and long-term therapeutic effects， and sound safety.

Objective:To evaluate the role of autophagy in hydrogen-rich solution-induced reduction of remifentanil-induced hyperalgesia in rats.Methods:Thirty-two clean-grade healthy male Sprague-Dawley rats, aged 2-3 months, weighing 240-260 g, were divided into 4 groups ( n=8 each) by a random number table method: incisional pain group (group I), remifentanil+ incisional pain group (group RI), hydrogen-rich solution+ remifentanil+ incisional pain group (group HRI), and hydrogen-rich solution + autophagy inhibitor+ remifentanil+ incisional pain group (MHRI group). The tail vein was catheterized, the equal volume of normal saline was intravenously infused for 60 min while the incisional pain model was developed in group I, and remifentanil was intravenously infused at a rate of 1 μg·kg -1·min -1 for 60 min while the incisional pain model was developed in RI, HRI and MHRI groups, hydrogen-rich solution 10 ml/kg was intraperitoneally injected at 10 min before preparing the model in group HRI, and 3-MA 15 mg/kg was intraperitoneally injected at 1 h before preparing the model in MHRI group, and the other treatments were similar to those previously described in group HRI. The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were determined at 24 h before and 2, 6, 24 and 48 h after the end of infusion. The rats were sacrificed under anesthesia after the behavioral testing, and the lumbar enlargement segment of the spinal cord was removed for determination of the expression of microtubule-associated protein 1 light chain 3Ⅱ (LC3Ⅱ), Beclin-1 and P62 by Western blot. Results:Compared with the baseline at T 0, the MWT was significantly decreased and TWL was shortened at T 1-4 in the four groups ( P<0.05). Compared with group I, the MWT was significantly decreased and TWL was shortened at T 1-4, the expression of LC3 II and Beclin-1 was up-regulated, and the expression of P62 was down-regulated in group RI and group HRI ( P<0.05). Compared with group RI, the MWT was significantly increased and TWL was prolonged at T 1-4 in group HRI and group MHRI, the expression of LC3 II and Beclin-1 was significantly up-regulated, and the expression of P62 was down-regulated in group HRI, and the expression of LC3 II and Beclin-1 was significantly down-regulated, and the expression of P62 was up-regulated in group MHRI ( P<0.05). Compared with group HRI, the MWT was significantly decreased and TWL was shortened at T 1-4, the expression of LC3 II and Beclin-1 was down-regulated, and the expression of P62 was up-regulated in group MHRI ( P<0.05). Conclusions:The mechanism by which hydrogen-rich solution alleviates hyperalgesia may be related to enhancing the level of autophagy in the spinal cord of rats with incisional pain induced by remifentanil.

This study was performed to investigate the inhibitory effects of Xuebijing injection(XBJ)on lipopolysaccharide(LPS)-induced inflammatory signals on EA.hy926 vascular endothelial cells and the underlying mechanism,and to provide a theoretical basis for the treatment of sepsis with XBJ.WST-1 assay was used to detect the effects of XBJ on the cell viability;Western blot analysis was performed to detect the protein expression levels of IκBα,p-p65,p-ERK,p-JNK,p-p38,p-AMAD17 in cell lysates and the content of sTLR4 fragment in the concentrated culture supernatants.ADAM17 sheddase activity in cells was detected by using a commercial available kit.Data showed that all of the TLR4-mediated inflammatory signals were significantly inhibited by the treatment of XBJ(P＜0.01).ADAM17 phosphorylation and shedding activity were induced by XBJ treatment,simultaneously the sTLR4 contents in the culture media were increased.XBJ-induced shedding of TLR4 was suppressed by the preteatment of 10 μmol/L TAPI-1(an ADAM17 inhibitor).Taken together,XBJ can induce the shedding of TLR4 from cell membrane by up-regulating ADAM17 shedding activity,thereby inhibiting the activation of TLR4-mediated intracellular inflammatory signals in EA.hy926 cells.

Scavenger receptor class B, member 2 (SCARB2) is linked to Gaucher disease and Parkinson's disease. Deficiency in the SCARB2 gene causes progressive myoclonus epilepsy (PME), a rare group of inherited neurodegenerative diseases characterized by myoclonus. We found that Scarb2 deficiency in mice leads to age-dependent dietary lipid malabsorption, accompanied with vitamin E deficiency. Our investigation revealed that Scarb2 deficiency is associated with gut dysbiosis and an altered bile acid pool, leading to hyperactivation of FXR in intestine. Hyperactivation of FXR impairs epithelium renewal and lipid absorption. Patients with SCARB2 mutations have a severe reduction in their vitamin E levels and cannot absorb dietary vitamin E. Finally, inhibiting FXR or supplementing vitamin E ameliorates the neuromotor impairment and neuropathy in Scarb2 knockout mice. These data indicate that gastrointestinal dysfunction is associated with SCARB2 deficiency-related neurodegeneration, and SCARB2-associated neurodegeneration can be improved by addressing the nutrition deficits and gastrointestinal issues.

Objective　To understand the infection status and typing of Wolbachia in Culex pipiens pallens population in coastal areas of Shandong Province, and to provide new research directions and theoretical basis for the prevention and control of mosquito-borne diseases. Methods　From June 2022 to August 2023, mosquito samples were collected from 8 sites in four coastal cities of Yantai, Qingdao, Rizhao, and Dongying in Shandong Province by light lure method. The collected samples were identified as Culex pipiens pallens by combining morphological and molecular methods. Then, using the PCR detection method established by the Wolbachia surface protein (wsp) gene sequence, the Wolbachia infection rate of Culex pipiens pallens collected in the field from 8 sites along the coast of Shandong Province was detected. In addition, the representative strain of Wolbachia was downloaded from the GenBank database, and the obtained gene sequences were subjected to phylogenetic analysis using Mega5.2 software for typing. Results　Wolbachia infection was found in all four coastal areas of Shandong Province, with an average infection rate of 80.8% (261/323). Among them, Yanti had the highest infection rate of 100% (46/46), while Wulian County, Rizhao City had the lowest infection rate of 60.6% (20/33). A total of 12 wsp haplotypes were identified, with 92.5% infection rates for Hap1, 70.0% for Hap2, and lower rates for Hap3 to Hap12. From the perspective of haplotype sources, Hap1 was detected in all 8 sampling sites, while other haplotypes were only detected in some geographical populations of sampling sites. Among them, Dongying District, Dongying City had the highest haplotype diversity, with six haplotypes detected. Phylogenetic tree analysis concluded that the Wolbachia strains found in all eight sampling points belonged to group B. Conclusions　Infection of Wolbachia group B is common in Culex pipiens pallens in coastal areas of Shandong Province. Still, there are certain differences in the haplotypes of Wolbachia infections in different regions. This provides a valuable theoretical basis for targeted prevention and control of specific mosquito-borne diseases in the region．
