Objective:To identify the vision care access in rural primary health institutions and the utilization of vision inspections among rural residents. Methods:Survey data was collected from primary health institutions ( town-ship health centers and village clinics) and households. The descriptive statistics and multivariate regression analysis were applied to analyze data. Results:The household survey data shows that 33. 2% of rural residents self-reported having poor vision, and 22. 1% of rural residents stated that they had ever used vision care (vision screening or vison examinations) . The health facilities survey data shows that 84% of township health centers and 44% of village clinics can provide vision care. The multivariate analysis shows that the vision care access in township health centers is sig-nificantly correlated with the probability of residents’ utilization of vision care, but there is no significant correlation between the provision of vision care in village clinics and its utilization. Conclusions:The vision care access is low in rural China though there is a huge demand therefore. Inadequate supply of primary vision care services in primary health institutions may result in low utilization among rural residents. It is suggested that the government further pro-mote the National Public Health Service Program and strengthen the capacity of primary health facilities to provide primary vision care. To do so, an increase in the utilization of vision care among rural residents can be expected, which would thereby reduce potential losses caused by further vision impairment.

A plasmids of continuous expressing shRNAs targeting the NDV NA-1 Phosphoprotein (P) gene was designed.Virus titration,Real Time RT-PCR,CPE indicated that P-specific siRNA could inhibit virus replication at 36 h post-virus infection.In future studies,a combination of siRNAs targeting the NP and L gene may be used as a tool to study NDV replication and antiviral therapy.

Characteristic clinical manifestations of Newcastle disease include leukopenia and immunosuppression. Peripheral blood mononuclear cells (PBMCs) are the main targets of Newcastle disease virus (NDV) infection. To survey changes in proteomic expression in chicken PBMCs following NDV infection, PBMC proteins from 30 chickens were separated using two-dimensional electrophoresis (2-DE) and subjected to mass spectrometry analysis. Quantitative intensity analysis showed that the expression of 78 proteins increased more than two-fold. Thirty-five proteins exhibited consistent changes in expression and 13 were identified as unique proteins by matrix assisted laser desorption ionization-time of flight mass spectrometer/mass spectrometer including three that were down-regulated and 10 that were up-regulated. These proteins were sorted into five groups based on function: macromolecular biosynthesis, cytoskeleton organization, metabolism, stress responses, and signal transduction. Furthermore, Western blot analysis confirmed the down-regulation of integrin-linked kinase expression and up-regulation of lamin A production. These data provide insight into the in vivo response of target cells to NDV infection at the molecular level. Additionally, results from this study have helped elucidate the molecular pathogenesis of NDV and may facilitate the development of new antiviral therapies as well as innovative diagnostic methods.

Objective:To explore the surgical method and therapeutic effect of repairing digital tip defect with free flap of proximal perforating branch of proper palmar digital artery.Methods:From March, 2009 to January, 2021, 15 patients with soft tissue defects at the tip of 16 digits were repaired with free perforator flap of proper palmar digital artery. The flap was obtained from the ulnar side of an index finger, on both sides of a middle finger and on the proximal side of the radial side of the ring finger. The size of flaps was 1.8 cm × 1.2 cm - 4.5 cm × 2.2 cm. The flap carried dorsal branch of proper palmar digital nerve and 0.5-4.5 cm of arteriae digitales palmares propriae. The donor digital artery was re-anastomosed in 3 cases 3 digits, transferred and anastomosed in 2 cases and un-anastomosed in 10 cases 11 digits. The dorsal branch of the proper palmar digital nerve in the flap was anastomosed with the proper palmar digital nerve of the finger stump at the recipient site to restore the sensation of flap, and the donor sites at the wrist transverse stripes or elbow transverse stripes were directly sutured. Regular follow-up via outpatient visit, telephone or WeChat interviews was conducted to observe the appearance, sensation and recovery of the flap and finger joint function.Results:After surgery, the flaps and donor site skin grafts of 15 cases with 16 digits were all survived, with first stage healing. A 4 months to 12 years follow-up showed that the flaps were in good texture and full shape with TPD at 7 - 11 mm. The joint function of digits was recovered well, and there was no complaint about uncomfortable donor site. According to the Michigan Hand Function Questionnaire, all 15 patients were satisfied with the overall appearance and function of the hands. According to TAM evaluation standard, all the digits of 15 patients were in excellent.Conclusion:Free flap of the proximal perforating branch of proper palmar digital artery is an ideal in the repair of digital tip soft tissue defect, as it has the advantages of an anatomical constant vessel, hidden donor site, less trauma caused, simple flap resection and good therapeutic effect.

OBJECTIVE To reveal the role of the basal forebrain(BF)GABAergic neurons in the regulation of isoflurane anesthesia and to elucidate the underlying neural pathways.METHODS The activity of BF GABAer-gic neurons was monitored during isoflurane anesthesia using a genetically encoded calcium indicator in Vgat-Cre mice of both sexes.The activity of BF GABAer-gic neurons was manipulated by chemogenetic and opto-genetic approaches.Sensitivity,induction time and emer-gence time of isoflurane anesthesia were estimated by righting reflex.The electroencephalogram(EEG)power and burst-suppression were monitored by EEG recording.The effects of activation of GABAergic BF-thalamic reticu-lar nucleus(TRN)pathway on isoflurane anesthesia were investigated with optogenetics.RESULTS The activity of BF GABAergic neurons was generally inhibited during isoflurane anesthesia,obviously decreased during the induction of anesthesia and gradually restored during the emergence from anesthesia.Activation of BF GABAergic neurons with chemogenetics and optogenetics promoted behavioral emergence from isoflurane anesthesia,with decreased sensitivity to isoflurane,delayed induction and accelerated emergence from isoflurane anesthesia.Optogenetic activation of BF GABAergic neurons prom-oted cortical activity during isoflurane anesthesia,with decreased EEG delta power and burst suppression ratio during 0.8%and 1.4%isoflurane anesthesia,respectively.Similar to the effects of activating BF GABAergic cell bod-ies,photostimulation of BF GABAergic terminals in the TRN also strongly promoted cortical activation and behav-ioral emergence from isoflurane anesthesia.CONCLU-SION The GABAergic neurons in the BF is a key neural substrate for general anesthesia regulation that facilitates behavioral and cortical emergence from general anesthe-sia via the BF-TRN pathway.

Objective:To investigate the application effect of medical sterile gloves-assisted cutting cloth samples in the repair of finger degloving injury.Methods:The clinical data of patients with finger skin and soft tissue degloving defects treated in Jiangnan Hospital Affiliated with Binjiang College of Zhejiang University of Traditional Chinese Medicine from April 2015 to December 2021 were analyzed retrospectively. Medical sterile gloves were used to make cloth samples of finger defects, and then the dorsal foot flap or toenail flap was cut according to the cloth samples to repair finger defects. The survival of flaps and the appearance of the fingers’ body were observed after surgery, and the patients’ satisfaction was investigated. The finger function was evaluated by the trial standard of upper limb function evaluation of the Hand Surgery Society of Chinese Medical Association.Results:A total of 12 patients with 13 fingers were enrolled. There were 9 males (10 fingers) and 3 females (3 fingers), aged 17-54, average of 37-year-old. There were 5 cases (5 fingers) in the left hand and 7 cases (8 fingers) in the right hand, all with unilateral finger injury. The size of the dorsal flaps and great toenail flaps harvested were appropriate, ranging from 5.5 cm×4.5 cm to 10.5 cm×5.8 cm. After surgery, all patients were regularly followed up for 3-15 months, an average of 7 months. All the dorsal flap and great toenail flap of the foot after surgery survived, and the appearance of the finger body was not bloated. All patients were very satisfied with the appearance and function of the hand, and the finger function was evaluated as excellent in 7 cases and good in 5 cases.Conclusion:The application of sterile gloves-assisted cutting cloth samples for the treatment of finger degloving injury can simplify the procedure, reduce donor damage, make up for the lack as much as needed, and the repaired fingers can obtain better shape and function.

[Objective] To explore the correlation between the 5-factor modified frailty index (mFI-5) and acute kidney injury (AKI) after laparoscopic radical nephrectomy in elderly patients with renal cancer, so as to provide reference for the prevention and treatment of postoperative AKI. [Methods] A retrospective analysis was conducted on the clinical data of 214 elderly patients (≥60 years) who underwent laparoscopic radical nephrectomy at our hospital during Dec.2018 and Dec.2021.Patients were divided into frail group (n=75, mFI-5≥2) and non-frail group (n=139, mFI-5<2). The incidence of AKI and sub items of mFI-5 were compared between the two groups.According to the occurrence of AKI, patients were divided into AKI group (n=77) and non-AKI group (n=137). Univariate and multivariate logistic analyses were conducted to identify risk factors of AKI.Receiver operating characteristic (ROC) curves were plotted to test the effectiveness of mFI-5 in predicting AKI. [Results] The incidence of AKI was significantly higher in the frail group than in the non-frail group (64.00% vs. 20.86%, P<0.05). Univariate analysis showed that the incidence of AKI was related to gender, diabetes, hypertension, nonfunctional independent status, weakness and split kidney glomerular filtration rate (GFR). Multivariate logistic regression analysis showed that male (OR=2.454, 95%CI: 1.193—5.047), complicated weakness (OR=6.580, 95%CI: 3.380—12.811), and low split kidney GFR (OR=0.945, 95%CI: 0.911—0.980) were independent risk factors of AKI (P<0.05). The area under the ROC curve of AKI predicted by mFI-5 was 0.711. [Conclusion] Preoperative mFI-5 score is an effective predictor of AKI in elderly patients undergoing laparoscopic radical nephrectomy.As patients with frailty have a higher risk of AKI, preoperative evaluation and monitoring should be strengthened and timely intervention should be taken to improve the prognosis.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
