Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ2=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

Objective:To investigate the clinical effect of free anterolateral thigh perforator flap(ALTPF) in reconstruction of temporal scalp defect after blood circulation reconstruction surgery for moyamoya disease.Methods:From May 2020 to July 2022, 7 patients with scalp defect after revascularisation of moyamoya disease were treated in Department of Hand and Foot Microsurgery, Henan Provincial People’s Hospital (People’s Hospital of Zhengzhou University). The patients were 4 males and 3 females, aged 33-59 years old, at 43 years old in average. There were 5 defects in left tempus and 2 in right tempus. The sizes of scalp defect were 4.5 cm × 5.5 cm-7.5 cm × 9.5 cm. Debridement and VSD management were primarily performed. After wounds were stabilised, ultrasound location of perforator vessels of ALTPFs was performed. Having confirmed that the perforator vessels were suitable for the surgical requirements, flap transfers were then performed. The descending branch of the lateral femoral circumflex artery was end-to-side anastomosed with the superficial temporal artery, and the descending branch of the lateral femoral circumflex vein was end-to-end anastomosed with the superficial temporal vein. Postoperative follow-up was conducted through outpatient clinic visits, telephone and WeChat reviews. Appearance, texture of ALTPFs and the flap donor sites were observed in follow-ups. Comparisons of the changes of nervous system before and after surgery were made. Cognitive function of the patients was assessed with the Mini Mental State Examination (MMSE), together with the Activities of Daily Living (ADL) .Results:All 7 flaps survived. One flap had vascular compromise 6 hours after surgery, and was rectified after surgical intervention. All the patients were included in the postoperative follow-up for 7-33 (average 19) months. All flaps had good appearance with soft texture. There was no obvious difference in colour comparing with the skin around the recipient region. The donor sites healed well without hypertrophic scar. Examinations of nervous system of the patients were found the same as that before surgery. Using Manual Muscle Testing (MMT), the average limb muscle strength of the patients was 4 before surgery and 4 after surgery, without change; Using the Ashworth assessment scale, the average preoperative and postoperative limb muscle tension in this group of patients was 1, without change; The Berg balance scale was used to evaluate the patient's balance function, with an average score of 42 before surgery and 42 after surgery, without any changes; There was no change in limb sensation before and after surgery; Using the MMSE, the average preoperative score and postoperative score of this group of patients were 25 points, without any change. Using the modified Barthel index scoring standard, the average preoperative score for this group of patients was 75 points, and the average postoperative score was 79 points, and the ADL of the patient had improved to various levels.Conclusion:Reconstruction of scalp defect with free ALTPF after revascularisation of moyamoya disease has obvious advantages, such as it closes the wound quickly, prevents infection and achieves a good appearance. This surgical procedure can produce a good clinical effect.

Objective:To study the protective effect and mechanism of Chaenomelis Fructus alcohol extract (CFE) on the synovium of rheumatoid arthritis (RA). Method:Sixty male SD rats were randomly divided into normal group and model group. RA model was made by injection of complete Freund's adjuvant, and then was randomly divided into model group, CFE low, medium and high dose group and Tripterygium glycoside group according to the inflammatory score. The CFE groups (0.15,0.30,0.60 g·kg-1·d-1) had intragastric administration once a day for 30 d after the model establishment. The blank control group and the model group were given the same volume saline water by gavage. After all the drugs were given, the blood, joint tissues and synovium tissue of rats were collected. The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factor (TNF)-α in serum were detected by enzyme linked immunosorbent assay (ELISA), the pathological changes of synovium were observed by hematoxylin eosin (HE) staining, and the expressions of B-cell lymphoma-2 (Bcl-2),Bcl-2 associated X protein (Bax) and death factor (Fas) in joints were detected by Western blot. Result:Compared with normal group, the swelling degree and inflammation index of rats' feet in model group increased significantly, the levels of inflammatory factors IL-1β, IL-6, TNF-α in serum increased (P<0.01), anti-inflammatory factor IL-10 decreased (P<0.01), the protein expression of Bax, Fas and Bcl-2 increased, and the statistical results of Bcl-2 showed significant difference (P<0.05). Compared with model group, the swelling degree and inflammatory index of the plantar of RA rats were improved in the middle and high dose groups of CFE (P<0.01), the pathological changes such as synovial tissue hyperplasia and inflammatory cell infiltration were reduced in each dose group, and the levels of IL-1β, IL-6 and TNF-α in serum were reduced (P<0.05), anti inflammatory factor IL-10 increased (P<0.05), the disorder of inflammatory cytokine in the model was corrected, Bax, Fas expression increased, Bcl-2 protein expression decreased (P<0.01). Conclusion:CFE can reduce the degree of inflammation in RA joint and has obvious anti RA effects, which may be related to the apoptosis of synoviocytes induced by CFE.
Résumé
Respiratory syncytial virus (RSV) is an RNA virus, which belongs to the paramyxoviridae family, and is transmitted by air droplets and close contact and the main pathogen causing acute lower respiratory tract infection in infants, the elderly and immunocompromised individuals.Although there have been studies on the prevention and treatment of RSV drugs and RSV infection in patients, many medical demands have not been met.And there is no specific antiviral therapy.The only two drugs approved to be applied in RSV prevention and treatment are perizol and ribavirin.However, the former must be used prophylactically, and primarily in high-risk children, while the latter is less effective, and some children even suffer from airway spasm.Therefore, it is urgent to propose new methods for prevention and treatment of RSV.In recent years, traditional Chinese medicine(TCM) has shown a good anti-RSV effect, with a fewer side effects, less resistance to drugs and broad-spectrum antiviral advantage.There are also newly developed biological and chemical anti-RSV drugs.Some new drugs have shown a good efficacy, with an extended half-life and reduced costs, such as fusion inhibitors, monoclonal antibodies.This paper reviews the research progress of anti-RSV drugs in the aspects of TCM, biological drug and chemical drugs, laying a foundation for the development of new anti-RSV drugs and the formulation of new therapeutic strategies.

Objective@#To investigate the factors associated with the anastomotic leakage after anterior resection in rectal cancer.@*Methods@#From January 2014 to January 2017 471 patients underwent Dixon procedure for rectal cancer in The Affiliated Hospital of Qingdao University. The data of those patients was collected and reviewed retrospectively. Inclusion criteria included: 1) rectal cancer confirmed by preoperative electron colonoscopy; 2) the standard of total mesorectal excision followed by the surgeon during the surgery; and 3) elective surgery. Exclusion criteria included multi-primary rectal cancer, secondary surgery for tumor recurrence, palliative surgery, Miles procedure, Hartmann procedure, hormone drugs used, presence of rheumatic and immune diseases, and distant metastasis of rectal cancer. The variables, including demograpic characteristics, ASA score, diabetes mellitus, preoperative radiochemotherapy, histopathologic grade, pathological T stage, laparoscopic or open surgery, distance of the tumor from the anal verge ≤5 cm, were analyzed to identify the risk factors for anastomotic leakage.@*Results@#Of 471 patients, 285 and 186 were men and women, respectively, with a mean age of 61 years (range, 31-92) years. Symptomatic clinically anastomotic leakage occurred in 31 patients (6.6%, 31/471) after Dixon procedure for rectal cancer. On univariate analysis, the occurrence of anastomotic leakage was associated with diabetes (χ2 = 10.972, P = 0.001) , serum albumin level < 35 g/L (χ2 = 9.784, P = 0.002) , neoadjuvant chemoradiotherapy (χ2 = 6.867, P = 0.009) , distance ≤5 cm between the tumor and anal edge (χ2 = 5.993, P = 0.014) , preventive colostomy (χ2 = 5.630, P = 0.018) , and the use of double-perfusion cannula for abdominal flushing (χ2 = 4.232, P = 0.040) . Multivariate analysis revealed that diabetes (OR = 3.632, 95%CI: 1.620-8.145, P = 0.002) , neoadjuvant chemoradiotherapy (OR = 3.177, 95%CI: 1.283-7.867, P = 0.012) and distance ≤5 cm between the tumor and anal edge (OR = 2.444, 95%CI: 1.172 - 5.059, P = 0.017) were independent risk factors for anastomotic leakage, while preventive colostomy (OR = 0.138, 95%CI: 0.056 - 0.345, P = 0.000) and the use of double-perfusion cannula for abdominal flushing (OR = 0.223, 95%CI: 0.086 - 0.575, P = 0.002) were independent protective factors for anastomotic leakage.@*Conclusions@#For patients with rectal cancer with diabetes, undergoing neoadjuvant chemoradiotherapy, or distance ≤5 cm between the tumor and anal edge, anastomotic leakage after anterior resection of rectal cancer must be paid attention. When necessary, preventive colostomy or use of double-perfusion cannula for abdominal flushing should be considered.

Objective: To observe the effect of electroacupuncture (EA) at Huantiao (GB 30) and Weizhong (BL 40) on thigmesthesia, gait function, and expression levels of serum immunoglobulin G (IgG) and immunoglobulin M (IgM) in rabbits with lumbar intervertebral disc herniation (LIDH). Methods: Forty healthy New Zealand rabbits were randomly divided into a blank control group, a model group, an EA at acupoint group and an EA at non-acupoint group, with 10 rabbits in each group. The LIDH pathological model of rabbit was established using the self-made LIDH model maker. The thigmesthesia and gait function of rabbits were recorded by Siegal method. The serum IgG and IgM expression levels were detected by enzyme-linked immunosorbent assay. Results: EA at Huantiao (GB 30) and Weizhong (BL 40) could improve the clinical symptoms of thigmesthesia and gait function, and inhibit the expressions of serum IgG and IgM in the LIDH rabbits, which were significantly different compared with those in the model group and EA at non-acupoint group. Conclusion: EA at Huantiao (GB 30) and Weizhong (BL 40) can improve the clinical symptoms of LIDH rabbits, which is associated with inhibition of the serum IgG and IgM expressions and reduction of the immunoinflammatory factor release. This may be one of the mechanisms of EA at Huantiao (GB 30) and Weizhong (BL 40) in the treatment of LIDH.

In accordance with the hearing curve, those patients were divided into four types, i.e., low and intermediate frequency descent type; high frequency descent type; fall flat type; and total deafness type. Each type was treated by four different treatment options, according to the unified design of the random table, and randomly selected one of the options for treatment. The efficacy of the patients with sudden deafness with vertigo and dizziness was analyzed statistically after the follow-up for 4 weeks. SPSS 13.0 software was used to analyze the data.</p><p><b>RESULTS</b>In August 2007 to October 2011, 33 hospitals in the country included 1 024 patients with sudden deafness in line with the inclusion criteria, of whom 296 (28.91%) were accompanied by vertigo/dizziness symptoms, 126 were males and 170 were females, with an average age of (41.2 ± 13.5) years old. types of the different audiometric curves of sudden deafness, the occurrence of complete deafness with vertigo/dizziness was the highest (44.93%), followed by flat down type (25.87%), high frequency descent type (21.28%) and low intermediate frequency descent type (18.54%). After the standard treatment, the vertigo and dizziness symptoms of the sudden deafness patients could disappear, and the hearing in each group was obviously improved. The hearing curative effect on patients accompanied by vertigo/dizziness of low frequency and intermediate frequency descent type was the best, and the total efficiency can reach up to 94.74%, with the cure rate of 68.42%; followed by flat type, in which the total effective rate was 80.76%, with the recovery rate of 22.12%; and the effects on patients in high frequency descent type and total deafness type effect were relatively poor, in which the total effective rates were 70.00% (recovery rate of 10.00%) and 65.32% (recovery rate of 5.65%), respectively. The total effective rate of patients with sudden deafness associated with halo had no statistical significance (P > 0.05), in comparison to that of patients without halo; but, the cure rate of patients with no vertigo/dizziness of total deafness and the high frequency decreased patients with sudden deafness was significantly higher than that of vertigo/dizziness patients, with a statistical difference (P < 0.05).</p><p><b>CONCLUSIONS</b>The patients with sudden deafness in each type have a certain proportion of vertigo/dizziness, especially the deaf type. The possibility of hearing complete recovery in patients with vertigo/dizziness was significantly lower than that without vertigo/dizziness.</p>
