Neuropathic pain, a debilitating condition caused by dysfunction of the somatosensory nervous system, remains difficult to treat due to limited understanding of its molecular mechanisms. Bioinformatics analysis identified cerebellin 2 (CBLN2) as highly enriched in human and murine proprioceptive and nociceptive neurons. We found that CBLN2 expression is persistently upregulated in dorsal root ganglia (DRG) following spinal nerve ligation (SNL) in mice. In addition, transcription factor SOX11 binds to 12 cis-regulatory elements within the Cbln2 promoter to enhance its transcription. SNL also induced SOX11 upregulation, with SOX11 and CBLN2 co-localized in nociceptive neurons. The siRNA-mediated knockdown of Sox11 or Cbln2 attenuated SNL-induced mechanical allodynia and thermal hyperalgesia. High-throughput sequencing of DRG following intrathecal injection of CBLN2 revealed widespread gene expression changes, including upregulation of numerous NF-κB downstream targets. Consistently, CBLN2 activated NF-κB signaling, and inhibition with pyrrolidine dithiocarbamate reduced CBLN2-induced pain hypersensitivity, proinflammatory cytokines and chemokines production, and neuronal hyperexcitability. Together, these findings identified the SOX11/CBLN2/NF-κB axis as a critical mediator of neuropathic pain and a promising target for therapeutic intervention.

Objective To analyze the status and gene subtype distribution of human papillomavirus(HPV)infec-tion in male patients in dermatology outpatient department,provide reference for the prevention and treatment of male HPV infection.Methods Male patients who visited and conducted HPV detection in the dermatology outpa-tient department of a hospital from January 2022 to March 2023 were retrospectively surveyed.Patients were divi-ded into five groups:viral warts group,dermatitis and rash group,urinary tract infection group,balanoposthitis group,and asymptomatic group.Relationship between genotype distribution and patient age,clinical diagnosis,and symptom types was statistically analyzed.Results A total of 1 035 male patients underwent HPV detection,out of which 567 were positive,with a positive detection rate of 54.78％.286,164,6,109,and 470 cases were from viral warts,dermatitis and rash,urinary tract infection,balanoposthitis,and asymptomatic group,respectively.21 sub-types of HPV were detected,with the top three subtypes being type 6(17.97％),11(12.37％),and 52(8.70％).The positive rate of single type HPV infection was 29.86％,accounting for 54.50％.Positive rates of infection,low-risk infection,and multiple mixed infection in different age groups were compared,differences were all statisti-cally significant(all P＜0.05).The positive infection rate in the age group of＜20 years old was higher than that in the age groups of 20-＜30,30-＜40,and 40-＜50 years old,differences were all statistically significant(all P＜0.05).Among the positive patients,199 cases(35.10％)had no clinical symptoms,while 368(64.90％)had clinical symptoms,mainly manifested as viral warts(40.74％,n=231).In viral warts group,HPV-positive pa-tients were mainly of low-risk type,accounting for 80.95％;In balanoposthitis group,HPV-positive patients were mainly of high-risk type,accounting for 84.78％;In asymptomatic group,HPV-positive patients were mainly infected with high-risk types,accounting for 86.43％.Conclusion HPV infection in male outpatient department of derma-tology is mainly single type infection.The clinical diagnosis of low-risk infection is mainly viral warts,while high-risk in-fection is mainly manifested as balanoposthitis.In asymptomatic group,positive infections are mainly of high-risk type.

OBJECTIVE: To compare the clinical efficacy and safety among three different entry points of needle knife, including tenderness point, intervertebral foramen point and articular process node, for lumbar disc herniation (LDH). METHODS: A total of 105 patients with LDH were randomly divided into a tenderness point group (35 cases, 1 case dropped off ), an intervertebral foramen point group (35 cases) and an articular process node group (35 cases, 1 case dropped off ). In the three groups, the needle knife was given at positive tenderness points of lumbosacral and hip, the external point of intervertebral foramen and the node of vertebral joint process respectively, once a week for a total of 4 times. The scores of Japanese Orthopaedic Association (JOA), Oswestry disability index (ODI), visual analogue scale (VAS) were recorded before treatment, 2 weeks and 4 weeks into treatment, and 3 months follow-up after treatment, and the clinical efficacy and safety was observed. RESULTS: Compared before treatment, the JOA scores in each group were increased 2, 4 weeks into treatment and in the follow-up (P<0.05); 4 weeks into treatment and in the follow-up, the JOA scores in the tenderness point group and the articular process node group were higher than those in the intervertebral foramen point group (P<0.05). Compared before treatment, except for ODI score 2 weeks into treatment in the intervertebral foramen point group, the ODI and VAS scores in each group were decreased 2, 4 weeks into treatment and in the follow-up (P<0.05), and the ODI scores in the tenderness point group and the articular process node group were lower than those in the intervertebral foramen point group (P<0.05). In 2 weeks into treatment, the VAS scores in the tenderness point group and the articular process node group were lower than those in the intervertebral foramen point group (P<0.05); in 4 weeks into treatment and follow-up, the VAS scores in the tenderness point group were lower than the other two groups (P<0.05). After treatment, the clinical efficacy of each group was similar (P>0.05); during the follow-up, the total effective rate in the tenderness point group was higher than that in the intervertebral foramen point group (P<0.05). There were no serious adverse events in each group. CONCLUSION The three different entry points of needle knife all could improve the symptoms of patients with LDH. The comprehensive effect of improving the subjective symptoms, lumbar function, pain degree and long-term curative effect is better in the tenderness point group.

OBJECTIVE: To observe the effect of electroacupuncture (EA) on vascular endothelial growth factor-C (VEGF-C), vascular endothelial growth factor receptor-3 (VEGFR-3), proinflammatory factors and apoptosis in myocardial tissue in mice with acute myocardial ischemia (AMI), and to explore the mechanism of EA for AMI. METHODS: Fifty male C57BL/6 mice were randomly divided into a sham operation group, a model group, an EA group, an inhibitor group and an inhibitor+EA group, 10 mice in each group. Except for the sham operation group, the mice in the remaining groups were intervented with ligation at the left anterior descending (LAD) coronary artery to establish AMI model. The mice in the sham operation group were intervented without ligation after thoracotomy. The mice in the EA group were intervented with EA at "Shenmen" (HT 7) and "Tongli" (HT 5), disperse-dense wave, 2 Hz/15 Hz in frequency, 1 mA in current intensity, 30 min each time, once a day, for 3 d. The mice in the inhibitor group were treated with intraperitoneal injection of SAR 131675 (12.5 mg•kg^-1•d^-1, once a day for 3 d). The mice in the inhibitor+EA group were injected intraperitoneally with SAR 131675 30 min before EA. The ECG before modeling, 30 min after modeling and 3 d after intervention was detected, and the ST segment displacement was recorded; after the intervention, the ELISA method was applied to measure the contents of serum creatine kinase isoenzyme (CK-MB), aspartate aminotransferase (AST) as well as tumor necrosis factor-α (TNF-α) and interleukin-23 (IL-23) in myocardial tissue; the HE staining method was used to observe the morphological changes of myocardial tissue; the immunofluorescence double labeling method was applied to measure the number of co-expression positive cells of VEGF-C/VEGFR-3 in myocardial tissue; the TUNEL method was used to detect the level of cardiomyocyte apoptosis; the Western blot method was applied to measure the protein expressions of VEGF-C, VEGFR-3, b-lymphoma-2 (Bcl-2), activated caspase-3 (Cleaved Caspase-3) and activated poly adenosine diphosphate ribose polymerase-1 (Cleaved PARP-1). RESULTS: Compared with the sham operation group, in the model group the ST segment displacement was increased (P<0.01); the contents of CK-MB, AST, TNF-α and IL-23 were increased (P<0.01); the arrangement of myocardial fibers was disordered, and interstitial inflammatory cell infiltration was obvious; the number of co-expression positive cells of VEGF-C/VEGFR-3 was decreased (P<0.01); the number of cardiomyocyte apoptosis was increased (P<0.01); the expressions of VEGF-C, VEGFR-3 and Bcl-2 were decreased (P<0.01); the expressions of Cleaved Caspase-3 and Cleaved PARP-1 were increased (P<0.01). Compared with the model group, in the EA group the ST segment displacement was decreased (P<0.01); the contents of CK-MB, AST, TNF-α, IL-23 were decreased (P<0.01); the severity of myocardial pathological injury was reduced; the number of co-expression positive cells of VEGF-C/VEGFR-3 was increased (P<0.01); the number of cardiomyocyte apoptosis was reduced (P<0.01); the expressions of VEGF-C, VEGFR-3 and Bcl-2 were increased (P<0.01); the expressions of Cleaved Caspase-3 and Cleaved PARP-1 were reduced (P<0.01). There was no significant difference in all the indexes between the model group and the inhibitor group (P>0.05). Compared with the model group, the protein expression of VEGF-C was increased in the inhibitor+EA group (P<0.01). Compared with the inhibitor group, in the EA group the ST segment displacement was decreased (P<0.01); the contents of CK-MB, AST, TNF-α, IL-23 were decreased (P<0.01); the severity of myocardial pathological injury was reduced; the number of co-expression positive cells of VEGF-C/VEGFR-3 was increased (P<0.05); the number of cardiomyocyte apoptosis was reduced (P<0.01); the expressions of VEGF-C, VEGFR-3 and Bcl-2 were increased (P<0.01); the expressions of Cleaved Caspase-3 and Cleaved PARP-1 were reduced (P<0.01). Compared with the inhibitor+EA group, all the indexes in the EA group were improved except the protein expression of VEGF-C (P<0.01). CONCLUSION EA could relieve the inflammatory reaction and apoptosis in AMI mice, and its mechanism may be related to activating VEGF-C/VEGFR-3 pathway and promoting lymphangion genesis.

Objective: To examine the safety and effectiveness of a new stent graft system for endovascular repair of abdominal aortic aneurysm(AAA). Methods: This is a prospective,multi-center,single-arm clinical trial. The patients with AAA treated with a new stent graft system were enrolled at 21 centers from September 2018 to September 2019 in China. Follow-up was performed before discharge, and at 30, 180, 360 days after operation, respectively. The primary safety endpoint was the incidence of major adverse events(MAE) within 30 days. The primary efficacy endpoint was the success rate of AAA treatment at 360 days. Secondary safety endpoints were the incidence of perioperative access complications and acute lower limb ischemia,all-cause mortality, AAA related mortality and incidence of serious adverse events (SAE) at 180 and 360 days. Secondary efficacy endpoints were the incidence of type Ⅰ or Ⅲ endoleak,stent displacement,and conversion to open surgery or re-intervention at 180 and 360 days. Results: One hundred and fifty-six patients were enrolled,including 137 males and 19 females. The age was (68.9±6.9) years (range:48.2 to 84.6 years).Maximum aneurysm diameter was (50.8±11.2) mm (range:25.0 to 85.0 mm),diameter of proximal landing zone was (21.2±2.5) mm (range:17.0 to 29.5 mm),and length of proximal landing zone was (31.4±13.0) mm (range:11.0 to 75.0 mm).The incidence of MAE was 1.3% (2/156) at 30 days,both were all-cause death cases. The success rate of AAA treatment was 88.5% (138/156) at 360 days. No perioperative access complication and acute lower limb ischemia occurred. All-cause mortality was 2.0% (3/154) at 180 days and 2.6% (4/153) at 360 days,and there was no AAA related death. The incidence of SAE was 23.0%(35/152) at 180 days and 30.5%(46/151) at 360 days, and no device-related SAE occurred. The incidence of type Ⅰor Ⅲ endoleak was 3.4% (5/147) at 180 days and 3.5% (5/144) at 360 days. Conclusion: The new stent graft system is easy to operate,and early-term safety and effectiveness results are expected.

With the aging process of population in the society, the prevalence of cardiovascular diseases (CVD) in China is increasing continuously and the number of dental patients with CVD is increasing gradually too. Due to the lack of guidelines for dental patients with CVD in our country, how to implement standardized preoperative evaluation and perioperative risk prevention remains a problem to be solved for dentists at present. The present expert consensus was reached by combining the clinical experiences of the expert group of the Fifth General Dentistry Special Committee, Chinese Stomatological Association and respiratory and cardiology experts in diagnosis and treatment for CVD patients, and by systematically summarizing the relevant international guidelines and literature regarding the relationship between CVD and oral diseases and the diagnosis and treatment of dental patients with heart failure, hypertension and antithrombotic therapy. The consensus aims to provide, for the dental clinicians, the criteria on diagnosis and treatment of CVD in dental patients in China so as to reduce the risk and complications, and finally to improve the treatment levels of dental patients with CVD in China.

OBJECTIVE: To explore the mechanisms underlying the proliferative inhibition of Chinese herbal medicine Kang-Ai injection (KAI) in gastric cancer cells. METHODS: Gastric cancer cell lines MGC803 and BGC823 were treated by 0, 0.3%, 1%, 3% and 10% KAI for 24, 48 and 72 h, respectively. The cell proliferation was evaluated by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. The apoptosis and cell cycle were evaluated by flow cytometry. Interleukin (IL)-6 mRNA and protein expression levels were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-linked immune sorbent assay (ELISA), respectively. The protein expression levels of cyclin A, cyclin E, cyclin B1, cyclin D1, p21, retinoblastoma (RB), protein kinase B (AKT), extracellular regulated protein kinases (ERK), signal transducer and activator of transcription (STAT) 1 and STAT3 were detected by Western blot. RESULTS: KAI inhibited the proliferation of MGC803 and BGC823 gastric cancer cells in dose- and time-dependent manner. After treated with KAI for 48 h, the proportion of G1 phase was increased, expression level of cyclin D1 and phosphorylation-RB were down-regulated, whereas the expression of p21 was up-regulated (all P<0.01). Furthermore, 48-h treatment with KAI decreased the phosphorylation level of STAT3, inhibited the mRNA and protein expressions of IL-6 (all P<0.01). IL-6 at dose of 10 ng/mL significantly attenuated the proliferative effect of both 3% and 10% KAI, and recovered KAI-inhibited STAT3 phosphorylation and cyclin D1 expression level (all P<0.01). CONCLUSION KAI exerted an anti-proliferative function by inhibiting IL-6/STAT3 signaling pathway followed by the induction of G₁ phase arrest in gastric cancer cells.

The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical micro-biome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenor-rhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.

Objective:This article analyzes the cognition and satisfaction evaluation of patients in medical alli-ance. Under the medical alliance mode,the present study tries to explore the choice of medical treatment of patients, the first diagnosis of primary health care institutions and its influencing factors, in order to provide reference for the construction of medical alliance. Methods:With the help of stratified sampling method,eighteen (18) medical alli-ances were selected from 16 districts and counties in Beijing. The survey questionnaire was designed to be used as the tool for data collection. A total of 1 280 patients in medical alliance participated in this study. The Chi-square Test and binary logistic regression model were used for statistical analysis. Results:59.12% of patients understand the medical association and related policies. 39.12% of the patients are satisfied with the medical association,51.44% of patients are willing to take first diagnosis at primary health care institutions. The distribution of medical resources in various districts is uneven. The type of hospital visited,the degree of understanding of medical alliance,the expe-rience of medical alliance and the satisfaction toward medical alliance will have an impact on the willingness about basic initial diagnosis,and the influence make a significant statistical sense. Conclusions:The Medical alliance con-struction in Beijing has achieved a certain effect,as first visit at primary health care institutions will be the initial for-mation. But the unbalanced distribution of medical resources in various districts,the service capacity of primary care institutions which does not meet the needs of patients,the insufficient sensitization of relevant policy and the current health insurance policy are seen as limiting factors to the development of medical alliance.
