The model of membranous nephropathy was established according to the modified Border method. The successfully modeling rats were divided into model group, benazepril group and Qizhi Tongluo Prescription low-, medium- and high-dosage groups using random number table method. Benazepril group was gavaged with benazepril hydrochloride 10 mg/kg, Qizhi Tongluo Prescription low-, medium- and high-dosage groups were gavaged with Qizhi Tongluo Prescription solution 1.22 g/kg, 2.43 g/kg and 4.86 g/kg, and blank group and model group were gavaged with equal volume of normal saline, once a day, for 4 weeks. The 24-hour urine was collected to detect the 24-hour urinary protein quantification, and the blood was taken from the abdominal aorta to detect the levels of total cholesterol (TC), triglyceride(TG), and serum albumin(ALB); the pathological changes of rat kidney were observed by light microscope and transmission electron microscope; the protein expressions of sonic hedgehog factor (Shh), zinc finger protein 1 (Gli1) and α-smooth muscle actin (SMA) in renal tissues were detected by immunohistochemistry; the protein expressions of Shh, Gli1, α-SMA, TGF-β1, Collagen Ⅳ and plasminogen activator inhibitor-1 (PAl-1) in renal tissues were detected by Western blot. Results:Compared with the model group, the quantitative level of 24-hour urinary protein of rats in each administration group decreased ( P<0.05), serum TC and TG levels increased ( P<0.05), ALB level decreased ( P<0.05), the positive expressions of Shh, Gli1, α-SMA protein in renal tissue decreased ( P<0.05), and the protein expressions of Shh, Gli1, α-SMA, Collagen Ⅳ, TGF-β1, PAI-1 in renal tissue decreased ( P<0.05). Conclusion:Qizhi Tongluo Prescription can improve renal interstitial fibrosis in membranous nephropathy rats, possibly by inhibiting the Shh/Gli1 signaling pathway to delay renal interstitial fibrosis.

Objective:This study aims to investigate the current application and the level of knowledge of intraoperative facial nerve monitoring among medical staff in China.Methods:A comprehensive online questionnaire was conducted among medical professionals across different regions in China from October 2022 to February 2023. The survey exclusively targeted departments specializing in otolaryngology, head and neck surgery, neurosurgery, and oral and maxillofacial surgery. The questionnaire covered various aspects including general information, intraoperative facial nerve monitoring practices, training history, indications for monitoring, parameters used during monitoring procedures, as well as factors influencing its implementation.Results:A total of 417 participants from 31 provincial, municipal, and autonomous regions were included. Intraoperative facial nerve monitoring was found to be implemented in 227 (54.4%,227/417) repondents of 53 institutions (24.9%, 53/213). The top three indications for implementing this technique were acoustic neuroma, parotid gland surgery, and modified middle ear surgery (mastoidectomy). Herein 81.1%(184/227) medical staff involved in intraoperative facial nerve monitoring had received relevant training, 57.3%(130/227)-92.1%(209/227) reported a lack of clear description regarding recording thresholds, stimulation currents/frequencies/wave widths.Conclusion:The majority of the institutions surveyed have not yet adopted intraoperative facial nerve monitoring. Furthermore, significant gaps concerning the procedure exist. It is imperative to establish standards or guidelines to promote its better development and application.

Objective:To explore the feasibility of non-invasive prenatal testing (NIPT) for detecting fetal chromosomal copy number variants (CNV).Methods:A retrospective analysis was carried out on NIPT positive samples in Suzhou Municipal Hospital from January 1, 2019 to December 31, 2021. The effect of NIPT on fetal CNV detection was assessed by comparison with the results of karyotype analysis and/or chromosomal microarray analysis (CMA).Results:Among the 525 NIPT positive samples, 146 were CNV cases, of which 84 were further verified by karyotyping and/or CMA, 29(34.5%) were true positive. Among them, 12 cases were pathogenic variants, 2 cases were likely pathogenic variants and 15 cases were variants of uncertain significance.Conclusion:NIPT could detect CNV with high accuracy, and to combine CNV detection and chromosomal aneuploidy detection has great significance to improve the prenatal and postnatal care.

Objective To propose diagnostic criteria for radicular lumbar disease(RLD)and evaluate its surgical outcomes.Methods A retrospective study was conducted on 31 patients with RLD who were admitted to Department of Spinal Surgery of our hospital from Mar.2020 to Oct.2023.The nerve root tension during the operation was recorded,and the surgical complications,visual analog scale(VAS)score,Oswestry disability index(ODI),Japanese Orthopaedic Association(JOA)score,and modified MacNab score were statistically analyzed.Results There were 13 males and 18 females,with an average age of(56.39±9.96)years.All the patients underwent modified transforaminal lumbar interbody fusion(TLIF),including 2 cases of single-level operation,22 cases of two-level operation,4 cases of three-level operation,2 cases of four-level operation,and 1 case of six-level operation.The follow-up duration was(15.29±4.34)months.The nerve root tension during the operation was higher(25.00[22.00,28.25]g),while it decreased immediately after the operation(2.00[0.00,3.00]g),with significant differences(P＜0.01).The VAS score,ODI and JOA score after operation were improved compared with those before operation(all P＜0.01).At the last follow-up,there were 24 cases of"excellent",5 cases of"good",2 cases of"fair",and no"poor"in the modified MacNab score,and the excellent and good rate was 93.55%(29/31).Surgical complications(including cerebrospinal fluid leakage and incision infection)were occurred in 1 case each.Conclusion The remarkable clinical feature of patients with RLD is high tension of nerve.These patients can be treated by modified TLIF to improve the nerve hypertonia;early and accurate diagnosis and timely intervention are the keys to a good prognosis.

Objective Genotypes(G)1,3,and 5 of the Japanese encephalitis virus(JEV)have been isolated in China,but the dominant genotype circulating in Chinese coastal areas remains unknown.We searched for G5 JEV-infected cases and attempted to elucidate which JEV genotype was most closely related to human Japanese encephalitis(JE)in the coastal provinces of China. Methods In this study,we collected serum specimens from patients with JE in three coastal provinces of China(Guangdong,Zhejiang,and Shandong)from 2018 to 2020 and conducted JEV cross-neutralization tests against G1,G3,and G5. Results Acute serum specimens from clinically reported JE cases were obtained for laboratory confirmation from hospitals in Shandong(92 patients),Zhejiang(192 patients),and Guangdong(77 patients),China,from 2018 to 2020.Seventy of the 361 serum specimens were laboratory-confirmed to be infected with JEV.Two cases were confirmed to be infected with G1 JEV,32 with G3 JEV,and two with G5 JEV. Conclusion G3 was the primary infection genotype among JE cases with a definite infection genotype,and the infection caused by G5 JEV was confirmed serologically in China.

Objective:To investigate the effect of low-dose ketamine on neuroinflammation and microcirculation in mice with traumatic brain injury (TBI).Methods:Sixty adult male C57BL/6 mice, weighing 22-28 g, were randomly divided into sham-operated group, TBI group, Sham+ketamine group, and TBI+ketamine group ( n=15). A controlled cortical impingement (CCI) method was used to establish TBI models in the later 2 groups. Sham+ketamine group and TBI+ketamine group were intraperitoneally injected with 30 mg/kg ketamine once daily for 3 d at 30 min after TBI; sham-operated group and TBI group were intraperitoneally injected same amount of saline at the same time points. Cerebral cortical blood flow in 6 mice from each group was measured by laser speckle contrast imaging (LSCI) before, immediately after, 30 min after, 1 d after and 3 d after modeling, respectively. Three d after modeling, immunohistochemical staining and immunofluorescent double label staining were used to detect the nuclear translocation of microglia markers, ionized calcin-antibody-1 (Iba-1) and nuclear factor (NF)-κB p65 in damaged cortical brain tissues in 6 mice from each group. The remaining 3 mice in each group were sacrificed and tissue plasma was extracted 3 d after modeling; levels of NF-κB p65, phosphorylated (p)-NF-κB p65, p-IκB and inducible nitric oxide synthase (iNOS) in cortical brain tissues were detected by Western blotting. Expressions of tumor necrosis factor-α (TNF-α), interleukin-1-β (IL-1β) and interleukin-6 (IL-6), iNOS, reactive oxygen species (ROS) and reactive nitrogen species (RNS) in cortical brain tissues were detected by ELISA. Results:LSCI indicated that, 3 d after modeling, relative blood flow in local cerebral microcirculation of TBI+ketamine group was significantly increased compared with that of TBI group ( P<0.05). Immunohistochemical staining indicated that compared with the sham-operated group and Sham+ketamine group, the TBI group and TBI+ketamine group had significantly increased number of Iba-1 positive cells in the cerebral cortex ( P<0.05); compared with the TBI group, the TBI+ketamine group had significantly decreased number of Iba-1 positive cells ( P<0.05). ELISA indicated that compared with the sham-operated group and Sham+ketamine group, the TBI group and TBI+ketamine group had significantly increased expressions of TNF-α, IL-1β, IL-6, iNOS, ROS and RNS in damaged cortical brain tissues ( P<0.05); compared with the TBI group, the TBI+ ketamine group had significantly decreased expressions of TNF-α, IL-1β, IL-6, iNOS, ROS and RNS in damaged cortical brain tissues ( P<0.05). Immunofluorescent double label staining indicated obviously inhibited NF-κB p65 nuclear translocation in TBI+ketamine group when it was compared with TBI group. Western blotting indicated that compared with the sham-operated group and Sham+ketamine group, the TBI+ketamine group had significantly increased iNOS, NF-κB p65, p-NF-κB p65 and P-IκB protein expressions in damaged cortical brain tissues ( P<0.05); compared with the TBI group, the TBI+ketamine group had significantly decreased protein expressions of iNOS, NF-κB p65, p-NF-κB p65 and p-IκB in damaged cortical brain tissues ( P<0.05). Conclusion:Low-dose ketamine reduces neuroinflammation and improves cerebral microcirculatory blood flow after open TBI, whose mechanism may be related to inhibition of microglia NF-κB/iNOS pathway.

Diabetic kidney disease （DKD） is the main cause of end-stage renal disease. Its high prevalence， mortality rate， and medical cost bring a heavy economic burden to society and families， and DKD has become one of the most important public health problems. Intestinal microecology is the most important and complex micro-ecosystem in the human body， which is involved in important life activities such as material and energy metabolism， immune system regulation， and signal transduction， thereby maintaining the dynamic balance of the human internal environment. The dynamic balance between the intestinal microecology and the body is essentially a Yin-Yang balance. Once this balance is broken， intestinal microbiota imbalance， intestinal mucosal barrier damage， immune dysfunction， and reduction of metabolite short-chain fatty acids （SCFAs） will occur， which play an important role in the progression of DKD. From the perspective of the Yin-Yang theory of traditional Chinese medicine （TCM）， the imbalance of intestinal microecology in DKD is equivalent to the excessive or insufficient constraint of Yin and Yang， or Yin deficiency affecting Yang， or Yang deficiency affecting Yin， or waning and waxing of Yin and Yang. For different pathogenesis changes， "Yin disease treated through Yang"， "treating Yin for Yang"， or "treating Yang for Yin" methods are adopted to regulate intestinal microbiota， inhibit immune inflammation， protect intestinal mucosal barrier， and increase SCFAs through TCM， thereby reconciling Yin and Yang to achieve the condition where "Yin is at peace and Yang is compact". Based on the Yin-Yang theory， this paper intended to interpret the scientific connotation of TCM in the treatment of DKD with intestinal microecology as the target and TCM in the treatment of DKD by regulating intestinal microecology as the breakthrough point to provide a novel insight for the occurrence and development of DKD and the mechanism of TCM.
