OBJECTIVE: To explore the clinical efficacy of Wenshen Chushi Decoction combined with low intensity pulsed ultrasound (LIPUS) on erectile dysfunction (ED) caused by renal deficiency and phlegm-dampness syndrome. METHODS: One hundred and twenty ED patients were included from the Department of Andrology in the First Hospital of Hunan University of Traditional Chinese Medicine. The patients in control group were treated with Wenshen Chushi Decoction. While the patients in observation group were treated with Wenshen Chushi Decoction combined with LIPUS for 8 consecutive weeks. After the treatment, the efficacy was evaluated using the International Index of Erectile Function-5 (IIEF-5) score, Penile Flow Index (PFI), Traditional Chinese Medicine Syndrome Score, Self-Rating Depression Scale (SDS) score, and Self-Rating Anxiety Scale (SAS) score. Safety was also observed. And the efficacy was followed up 4 weeks after the end of treatment. RESULTS: Fifty-seven cases were enrolled into control group finally with 55 cases in the treatment group. After the treatment, all the patients in both of groups showed an improvement in IIEF-5 scores (P<0.01). Compared with the control group (19.09 ± 2.22), the IIEF-5 score in observation group (20.42 ± 2.39) increased significantly (P<0.01). After the treatment, the scores of PFI, TCM syndrome and SDS in both groups decreased (P<0.01, P<0.05, P<0.01). Compared with the control group (［3.77 ± 1.21］, ［9.91 ± 1.71］ and ［39.88 ± 2.63］ points), the observation group (［2.92 ± 1.08］, ［4.78 ± 1.45］, and ［34.51 ± 2.09］ points） showed a more significant decrease (P<0.01). There was no significant difference in total effective rate between the two groups (P>0.05). During follow-up, the IIEF-5 scores of both groups of patients were higher than those before (P<0.05, P<0.01), and the observation group score was higher than that in the control group (［17.15 ± 3.37］ vs ［13.63 ± 1.96］, P<0.01). No adverse reaction and abnormality of indicators occurred in both of two groups. CONCLUSION Wenshen Chushi Decoction has a significant therapeutic effect on ED caused by renal deficiency and phlegm-dampness syndrome. It can not only improve the quality of erection, but also improve the physical and mental symptoms associated with ED， which makes therapeutic effect lasting longer.

Objective:To investigate the techniques of digit-tip replantation with anastomosis of superior digital arch artery in children and to evaluate the clinical effects.Methods:From January 2020 to September 2022, 62 children (62 digits) with completely severed digit-tips were admitted to the Department of Paediatric Orthopaedics, Suzhou Ruihua Orthopaedic Hospital. All the injury planes were distal to the nail root. All arterial dissections were distal to the digital arterial arch with the vessel calibre from 0.15 mm to 0.35 mm. The superior arch arteries of the digital arterial arch were successfully anastomosed. After surgery, a significant blood flux to the replanted digit body were observed. Postoperative necroses or failures were analysed for the causes. All children with survived digit-tips were entered into scheduled follow-ups through a combination of visit of outpatient clinics or via WeChat and telephone reviews. Postoperative follow-up included digit body fullness, motion of distal interphalangeal joint, nail growth, scarring, and response of the replanted digit-tips to needling. Clinical outcomes were evaluated according to the evaluation criteria for finger replantation function.Results:Of the 62 replanted digit-tips, 56 survived after replantation. Two digits had wound infection after surgery, and survived by dressing change and applying sensitive antibiotics. Necrosis occurred in 6 replanted digit-tips, of which 2 necrotic digit bodies were amputated, and the stumps at the distal interphalangeal joint were repaired. The other 4 necrotic digits were healed after dressing change under the scab due to a smaller digit body. A total of 52 children (including 2 survivals from postoperative infection after dressing changes and 4 survivals with healing underneath-eschar after necrosis) and with 10 lost during follow-up (including 2 with stump repairs after necrosis). The follow-up period ranged from 2 to 30 months, with an average of 6 months. The shape and function of replanted digit-tips recovered well. According to the evaluation criteria for finger replantation function, 44 digits were of excellent, 6 of good, and 2 of fair.Conclusion:In children, the superior arch arteries of digital arterial arches of the digit-tips are small in diameter. However, the vessels in smaller calibres can be anastomosed, should proper surgical techniques are applied. Therefore, due to the satisfactory outcomes, microsurgeons should try the best efforts to replant a digit severed at the plane of digit-tip.

Objective:To deeply analyze the effect path of shared decision making(SDM)level on the quality of family doctor contracted service for multimorbidity among the elderly population,and to provide reference for promoting the health management of chronic diseases,improving the patient's medical experience and the quality of contracted service.Methods:A multi-stage random sampling method was used to conduct a questionnaire survey on 599 elderly patients with multimorbidity and their corresponding 63 contracted doctors in Wuhan and Guiyang.The hierarchical regression model was used to analyze the effect of SDM level on the quality of contracted services.Results:The score of SDM in elderly patients with multimorbidity in the central and western regions of China was 32.07±6.46,and the score of family doctor contracted service quality was 95.20±8.73,among which the scores of economy and vertical continuity were lower.The results of hierarchical regression model analysis showed that the level of SDM had a positive impact on the quality of contracted services(β=0.369,P＜0.05),and family doctors had a positive moderating effect on the degree of trust in contracted patients(β=0.548,P＜0.05).Conclusion:The level of SDM and the quality of contract service for elderly patients with multimorbidity in the central and western regions of China are at a medium level and still need to be improved.Shared decision-making significantly improves the quality of contracted service.The degree of trust in contracted patients strengthens the positive effect of SDM on service quality.In the future,we should strengthen the SDM,standardize the referral service of patients with chronic diseases,strengthen the communication and trust between doctors and patients,and effectively improve the quality of family doctor contracted service.

Objective:To explore the application value and treatment effects of multiple free anterolateral perforator flaps of calf for reconstruction of multiple digital wounds in single hand.Methods:From August 2020 to March 2022, 12 patients with soft tissue defects in 35 digits were treated in Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. Ten patients were male and 2 were female, aged 25 to 58 years old. Of the patients, 1 had soft tissue defects in 5 digits, 3 in 4 digits, 2 in 3 digits and 6 in 2 digits. The size of defects was from 1.2 cm ×1.2 cm to 7.0 cm×3.5 cm after debridement. The vascular perforators discovered from intraoperative explorations were found originating from the superficial peroneal artery in 24 flaps, from the peroneal artery in 7 flaps and from the anterior tibial artery in 4 flaps. During surgery, the perforator artery and accompanying veins of the flaps were anastomosed with the proper digital artery and palmar or dorsal subcutaneous veins in the recipient site, respectively. The size of the flaps was from 1.5 cm×1.5 cm to 7.5 cm×4.0 cm. No nerve was affected in the surgery. The wound at donor sites in the calf was sutured directly. Regular postoperative follow-ups were conducted at outpatient clinics. The comprehensive evaluation scale of flap was used to assess the conditions of the donor and recipient sites.Results:In this study, all 35 soft tissue defects of digits in 12 patients were reconstructed by the anterolateral perforator flaps of calf. All the 35 flaps survived after surgery, with a 100% of survival rate. The patients were instructed to carry out early functional training after surgery. Follow-up lasted 6 to 24 months, with an average of 11 months. Twenty-five flaps were found in slightly swollen, and further flap thinning surgery were carried out 3 months after the primary surgery, while the rest of the flaps had good appearance and texture. At 6 months after surgery, all flaps recovered a partial deep and shallow sensory and sense of touch. All wound at donor sites in calf had one-stage healing without dysfunction. The comprehensive evaluation scale was excellent in 28 flaps and good in 7 flaps. The excellent and good rate was 100%.Conclusion:It is an effective method to use multiple free anterolateral perforator flaps of calf to reconstruct multiple digit defects in single hand. The flaps can be conveniently harvested and the multiple digital defects in single hand can be reconstructed in primary surgery with small damages to the donor sites and together with satisfactory clinical outcomes.

Vascular anastomosis is one of the most basic techniques of microsurgery, and the quality of anastomosis largely determines the success of the surgery. With the continuous development of microsurgical techniques, more and more new technologies have been used in vascular anastomosis, but hand suturing is still the "gold standard" method for microvascular anastomosis. This article summarized the advantages and disadvantages as well as application of traditional microvascular suturing techniques and improved techniques and their methods at home and abroad, aiming to provide reference for clinical application of microvascular suturing techniques.

This study aims to systematically evaluate the clinical efficacy and safety of Kushen Gelatum combined with antibiotics for treating bacterial vaginosis. The randomized controlled trial(RCT) of Kushen Gelatum for treating bacterial vaginosis were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, and Cochrane Library with the time interval from inception to January 2023. Data were extracted from the included RCT by 2 investigators, including the sample size, characteristics of patients, interventions and controls, outcome indicators, and adverse effects. The Cochrane collaboration network's bias risk assessment tool was used for methodolo-gical quality evaluation of the included trials. RevMan 5.4 was employed to perform the Meta-analysis. A total of 19 RCTs were inclu-ded, involving 1 980 patients with bacterial vaginosis. Meta-analysis showed that, compared with nitroimidazoles alone, Kushen Gelatum + nitroimidazoles improved the total response rates in terms of clinical symptoms and laboratory tests(RR=1.24, 95%CI[1.13, 1.36], P<0.000 01), laboratory tests(RR=1.16, 95%CI[1.06, 1.26], P=0.000 9), and clinical symptoms(RR=1.26, 95%CI[1.08, 1.46], P=0.003), and reduced the leukocyte esterase positive rate(RR=0.29, 95%CI[0.17, 0.48], P<0.000 01) and the recurrence rate(RR=0.37, 95%CI[0.23, 0.58], P<0.000 1). Compared with lincomycin antibiotics(clindamycin) alone, Kushen Gelatum + lincomycin antibiotics(clindamycin) improved the total response rates in terms of clinical symptoms and laboratory tests(RR=1.18, 95%CI[1.06, 1.31], P=0.003) and laboratory tests(RR=1.27, 95%CI[1.04, 1.54], P=0.02), reduced the recurrence rate(RR=0.20, 95%CI[0.05, 0.75], P=0.02), and shortened the time to relief of burning sensation(MD=-1.70, 95%CI[-2.15,-1.26], P<0.000 01), vaginal itching(MD=-0.82, 95%CI[-1.30,-0.34], P=0.000 8), and abnormal leucorrhea(MD=-1.52, 95%CI[-1.98,-1.06], P<0.000 01). Compared with nitroimidazoles + probiotics, Kushen Gelatum + nitroimidazoles + probiotics improved the total response rate in terms of clinical symptoms and laboratory tests(RR=1.18, 95%CI[1.02, 1.36], P=0.03) and reduced the recurrence rate(RR=0.27, 95%CI[0.09, 0.76], P=0.01). Kushen Gelatum combined with antibiotics demonstrates a potential therapeutic effect on bacterial vaginosis, whereas the number and quality of the relevant clinical studies remain to be improved. The process of clinical trial should be standardized to improve the quality of evidence, so as to provide strong evidence to guide the application of Kushen Gelatum in clinical practice.

AIM: To investigate the changes in retinal nerve fiber layer(RNFL)and macular retinal thickness(MRT)in children with refractive abnormalities and amblyopia, and their predictive value of outcome.METHODS: A total of 168 children with myopic refractive abnormalities and monocular amblyopia admitted to our hospital from January 2020 to October 2022 were selected as the observation group, with 118 cases of mild to moderate amblyopia and 50 cases of severe amblyopia, and 168 children with normal vision were included as the control group in a 1:1 ratio during the same period. The changes of RNFL and MRT in two groups of children were statistically counted, and the correlation between the severity of refractive abnormalities and RNFL and MRT in children with amblyopia was analyzed. Additionally, the observation group was divided into effective subgroup and ineffective subgroup based on the therapeutic effect. The general information, as well as RNFL and MRT of the effective subgroup and the ineffective subgroups before and after treatment were compared. Logistic was used to analyze the factors influencing efficacy, and ROC curves was plotted to analyze the predictive value of RNFL and MRT alone or in combination for efficacy.RESULTS: RNFL and MRT of cases of severe amblyopia were higher than those of the mild to moderate amblyopia and the control groups(all P<0.05); the severity of amblyopia in children with refractive abnormalities is positively correlated with RNFL and MRT(rs=0.745 and0.724, both P<0.001); among patients of mild to moderate and severe, there were statistically significant differences between the effective and ineffective subgroups in terms of initial treatment age, fixation form, treatment compliance, as well as RNFL, MRT, and their differences before and 1mo postoperatively(all P<0.05). Logistic analysis showed that initial treatment age, fixation nature, treatment compliance, RNFL and MRT before and 1mo postoperatively were all factors influencing the therapeutic effect of amblyopia with refractive abnormalities in children(all P<0.05); after 1mo of treatment, the combined prediction of RNFL and MRT was significantly better than that of single prediction in children with mild to severe amblyopia.CONCLUSION:There are differences in RNFL and MRT in children with abnormal refractive amblyopia, and they are closely related to the different degrees and curative effects of children. The combination of RNFL and MRT after 1mo of treatment has certain value in predicting children with different degrees of abnormal refractive amblyopia.

Objective:To develop and validate a nomogram model for predicting microvascular invasion (MVI) in hepatocellular carcinoma (HCC) based on preoperative enhanced computed tomography imaging features and clinical data.Methods:The clinical data of 210 patients with HCC undergoing surgery in the Second Affiliated Hospital of Anhui Medical University from May 2018 to May 2022 were retrospectively analyzed, including 172 males and 38 females, aged (59±10) years old. Patients were randomly divided into the training group ( n=147) and validation group ( n=63) by systematic sampling at a ratio of 7∶3. Preoperative enhanced computed tomography imaging features and clinical data of the patients were collected. Logistic regression was conducted to analyze the risk factors for HCC with MVI, and a nomogram model containing the risk factors was established and validated. The diagnostic efficacy of predicting MVI status in patients with HCC was assessed by receiver operating characteristic (ROC) curve, calibration curves, decision curve analysis (DCA), and clinical impact curve (CIC) of the subjects in the training and validation groups. Results:The results of multifactorial analysis showed that alpha fetoprotein ≥400 μg/ml, intra-tumor necrosis, tumor length diameter ≥3 cm, unclear tumor border, and subfoci around the tumor were independent risk factors predicting MVI in HCC. A nomogram model was established based on the above factors, in which the area under the curve (AUC) of ROC were 0.866 (95% CI: 0.807-0.924) and 0.834 (95% CI: 0.729-0.939) in the training and validation groups, respectively. The DCA results showed that the predictive model thresholds when the net return is >0 ranging from 7% to 93% and 12% to 87% in the training and validation groups, respectively. The CIC results showed that the group of patients with predictive MVI by the nomogram model are highly matched with the group of patients with confirmed MVI. Conclusion:The nomogram model based on the imaging features and clinical data could predict the MVI in HCC patients prior to surgery.

OBJECTIVE: The mode of human immunodeficiency virus (HIV) transmission via injection drug use (IDU) still exists, and the recent shift in IDU-related transmission of HIV infection is largely unknown. The purpose of this study was to analyze the spatiotemporal sources and dynamics of HIV-1 transmission through IDU in Guangxi. METHODS: We performed a molecular epidemiological investigation of infections across Guangxi from 2009 to 2019. Phylogenetic and Bayesian time-geographic analyses of HIV-1 sequences were performed to confirm the characteristics of transmission between IDUs in combination with epidemiological data. RESULTS: Among the 535 subjects, CRF08_BC (57.4%), CRF01_AE (28.4%), and CRF07_BC (10.7%) were the top 3 HIV strains; 72.6% of infections were linked to other provinces in the transmission network; 93.6% of sequence-transmitted strains were locally endemic, with the rest coming from other provinces, predominantly Guangdong and Yunnan; 92.1% of the HIV transmission among people who inject drugs tended to be transmitted between HIV-positive IDUs. CONCLUSION HIV recombinants were high diversity, and circulating local strains were the transmission sources among IDUs in Guangxi. However, there were still cases of IDUs linked to other provinces. Coverage of traditional prevention strategies should be expanded, and inter-provincial collaboration between Guangxi, Yunnan, and Guangdong provinces should be strengthened.

This study aimed to observe the effect of terpinen-4-ol(T4O) on the proliferation of vascular smooth muscle cells(VSMCs) exposed to high glucose(HG) and reveal the mechanism via the Krüppel-like factor 4(KLF4)/nuclear factor kappaB(NF-κB) signaling pathway. The VSMCs were first incubated with T4O for 2 h and then cultured with HG for 48 h to establish the model of inflammatory injury. The proliferation, cell cycle, and migration rate of VSMCs were examined by MTT method, flow cytometry, and wound healing assay, respectively. The content of inflammatory cytokines including interleukin(IL)-6 and tumor necrosis factor-alpha(TNF-α) in the supernatant of VSMCs was measured by enzyme-linked immunosorbent assay(ELISA). Western blot was employed to determine the protein levels of proliferating cell nuclear antigen(PCNA), Cyclin D1, KLF4, NF-κB p-p65/NF-κB p65, IL-1β, and IL-18. The KLF4 expression in VSMCs was silenced by the siRNA technology, and then the effects of T4O on the cell cycle and protein expression of the HG-induced VSMCs were observed. The results showed that different doses of T4O inhibited the HG-induced proliferation and migration of VSMCs, increased the percentage of cells in G_1 phase, and decreased the percentage of cells in S phase, and down-regulated the protein levels of PCNA and Cyclin D1. In addition, T4O reduced the HG-induced secretion and release of the inflammatory cytokines IL-6 and TNF-α and down-regulated the expression of KLF4, NF-κB p-p65/NF-κB p65, IL-1β, and IL-18. Compared with si-NC+HG, siKLF4+HG increased the percentage of cells in G_1 phase, decreased the percentage of cells in S phase, down-regulated the expression of PCNA, Cyclin D1, and KLF4, and inhibited the activation of NF-κB signaling pathway. Notably, the combination of silencing KLF4 with T4O treatment further promoted the changes in the above indicators. The results indicate that T4O may inhibit the HG-induced proliferation and migration of VSMCs by down-regulating the level of KLF4 and inhibiting the activation of NF-κB signaling pathway.
