ObjectiveTo evaluate the clinical efficacy of Huayu Tongluo Formula （化瘀通络方， HTF） in patients with mid-stage diabetic kidney disease of blood stasis syndrome and explore its potential mechanisms. MethodsA multi-center， randomized， double-blind， placebo-controlled clinical trial was conducted. Ninety patients of mid-stage diabetic kidney disease of blood stasis syndrome were divided into a control group of 46 cases and a treatment group of 44 cases. Both groups received conventional western medicine treatment， the treatment group additionally taking HTF， while the control group taking a placebo of the formula. The treatment was administered once daily for 24 weeks. The primary outcomes included 24-hour urine total protein （24 h-UTP）， serum albumin （Alb）， glycated hemoglobin （HbA1c）， and serum creatinine （Scr）.The secondary outcomes included changes in levels of endothelin-1 （ET-1）， nitric oxide （NO）， vascular endothelial growth factor （VEGF）， and traditional Chinese medicine （TCM） syndrome scores before and after treatment. Clinical efficacy was evaluated based on TCM syndrome scores and overall disease outcomes. Adverse reactions and endpoint events were recorded. ResultsIn the treatment group after treatment， 24 h-UTP， ET-1， and VEGF levels significantly decreased （P＜0.05）， Alb and NO levels significantly increased （P＜0.05）； while the TCM syndrome scores for edema， lumbar pain， numbness of limbs， dark purple lips， dark purple tongue or purpura， and thin， rough pulse all significantly decreased （P＜0.05）. In the control group， no significant changes were observed in any of the indicators after treatment （P＞0.05）.Compared with the control group， the treatment group showed significant reductions in 24 h-UTP， ET-1， and VEGF levels， and increases in Alb and NO levels （P＜0.05）. The TCM syndrome scores for edema， lumbar pain， dark purple tongue or purpura， and thin， rough pulse were all lower in the treatment group than in the control group （P＜0.05）. The total effective rate of TCM syndrome in the treatment group was 59.09% （26/44）， and the overall clinical effective rate was 45.45% （20/44）. In the control group， these rates were 15.22% （7/46） and 8.7% （4/46）， respectively， with the treatment group showing significantly better outcomes （P＜0.05）. A total of 7 adverse events occurred across both groups， with no significant difference （P＞0.05）. No endpoint events occurred during the study. ConclusionOn the basis of conventional treatment of Western medicine， HTF can further reduce urinary protein levels and improve clinical symptoms in patients with mid-stage diabetic kidney disease of blood stasis syndrome. The mechanism may be related to its effects on endothelial function.

Objective To investigate the prevalence and molecular characteristics of Anaplasma infections in sheep and goats in Anhui Province in 2020, so as to provide insights into ovine anaplasmosis prevention and control. Methods A total of 355 fresh blood samples were collected from 7 sheep and goat farms in Linquan County of Fuyang City, Lixin County of Bozhou City, Yu'an District of Lu'an City, Wangjiang County of Anqing City, Nanling County of Wuhu City, and Tianchang City and Fengyang County of Chuzhou City in Anhui Province from June to December 2020. A. bovis and A. phagocytophilum 16S ribosomal RNA (16S rRNA) gene, A. ovis major surface protein 4 (MSP4) gene and A. capra citric acid synthase (gltA) gene were amplified using PCR assay in all blood samples, and the prevalence of A. bovis, A. phagocytophilum, A. ovis and A. capra infections was calculated in sheep and goats. In addition, the positive amplification products were sequenced and subjected to genetic evolutionary analysis. Results The overall prevalence of Anaplasma infections was 17.5% (62/355) in sheep and goats in Anhui Province, and the prevalence of A. bovis, A. phagocytophilum, A. ovis and A. capra infections was 2.8% (10/355), 2.5% (9/355), 2.5% (9/355), and 7.0% (25/355), while the prevalence of A. bovis and A. phagocytophilum, A. phagocytophilum and A. ovis, A. phagocytophilum and A. capra and A. bovis, A. phagocytophilum and A. ovis co-infections was 0.8% (3/355), 1.1% (4/355), 0.3% (1/355) and 0.3% (1/355), respectively. No Anaplasma was detected in the sheep and goat farms in Fengyang County, while at least three Anaplasma species were detected in other sheep and goat farms, with co-infections of multiple Anaplasma species identified. The prevalence of Anaplasma infections was 14.7% (24/163) in goats and 19.8% (38/192) in sheep, and the prevalence of Anaplasma infections was 31.0% (31/100) in goats and sheep under 6 months of age, and 12.2% (31/255) in goats and sheep at ages of 6 months and older, respectively. A. bovis, A. phagocytophilum, A. ovis and A. capra were identified in sheep and goats of different breeds and ages. Conclusions Multiple Anaplasma species infections were commonly prevalent in goats and sheep in Anhui Province in 2020, notably A. phagocytophilum, A. ovis and A. capra, which have zoonotic risks. Improved surveillance and prevention and control of Anaplasma infections are required in sheep and goats in Anhui Province.

Background: and Purpose X-linked Charcot-Marie-Tooth disease type 1 (CMTX1) is characterized by peripheral neuropathy with or without episodic neurological dysfunction. We performed clinical, neuropathological, and genetic investigations of a series of patients with mutations of the gap-junction beta-1 gene (GJB1) to extend the phenotypic and genetic description of CMTX1. Methods: Detailed clinical evaluations, sural nerve biopsy, and genetic analysis were applied to patients with CMTX1. Results: We collected 27 patients with CMTX1 with GJB1 mutations from 14 unrelated families. The age at onset (AAO) was 20.9±12.2 years (mean±standard deviation; range, 2–45 years). Walking difficulties, weakness in the legs, and pes cavus were common initial symptoms. Compared with female patients, males tended to have a younger AAO (males vs. females=15.4±9.6 vs. 32.0±8.8 years, p=0.002), a longer disease course (16.8±16.1 vs. 5.5±3.8 years, p=0.034), and more-severe electrophysiological results. Besides peripheral neuropathy, six of the patients had special episodic central nervous system (CNS) evidence from symptoms, signs, and/or reversible white-matter lesions. Neuropathology revealed the loss of large myelinated fibers, increased number of regenerated axon clusters with abnormally thin myelin sheaths, and excessively folded myelin. Genetic analysis identified 14 GJB1 variants, 6 of which were novel. Conclusions These findings expand the phenotypic and genetic spectrum of CMTX1. Although CMTX1 was found to have high phenotypic and CNS involvement variabilities, detailed neurological examinations and nerve conduction studies will provide critical clues for accurate diagnoses. Further exploration of the underlying mechanisms of connexin 32 involvement in neuropathy or CNS dysfunction is warranted to develop promising therapies.

Objective To evaluate the effect of different techniques of hepatic artery reconstruction on postoperative hepatic artery complications and clinical prognosis in liver transplantation. Methods Clinical data of 140 liver transplant recipients were retrospectively analyzed. All recipients were divided into the conventional hepatic artery reconstruction group (n=123) and special hepatic artery reconstruction group (n=17) according to hepatic artery reconstruction methods. Intraoperative and postoperative clinical indexes, the incidence of postoperative hepatic artery complications and survival rate were compared between two groups. Results The alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels at postoperative 1 d, total bilirubin (TB) at postoperative 7 d and prothrombin time international normalized ratio (PT-INR) at postoperative 30 d in special hepatic artery reconstruction group were higher than those in conventional hepatic artery reconstruction group, and the differences were statistically significant (all P < 0.05). There were no significant differences in the operation time, anhepatic phase, intraoperative blood loss, intraoperative transfusion volume of red blood cells, cold or warm ischemia time, the length of intensive care unit (ICU) stay, the length of hospital stay and postoperative blood flow of liver allograft between two groups (all P > 0.05). In the conventional hepatic artery reconstruction group, 5 recipients developed hepatic artery complications, whereas no hepatic artery complications occurred in the special hepatic artery reconstruction group, with no significant difference between two groups (P > 0.05). In the special hepatic artery reconstruction group, the 1-, 3- and 5-year cumulative survival rates were equally 82.4%, compared with 85.0%, 78.9% and 75.6% in the conventional hepatic artery reconstruction group, respectively. There was no significant difference between two groups (all P > 0.05). Conclusions When hepatic artery variations and (or) lesions are detected in donors and recipients, use of special hepatic artery reconstruction may effectively restore the hepatic arterial blood flow of liver allograft after liver transplantation, and will not affect the incidence of hepatic artery complications and survival rate of the recipients following liver transplantation.

Objective To summarize clinical experience of transabdominal pericardial anastomosis of suprahepatic vena cava of the donor and right atrium of the recipient in liver transplantation for Budd-Chiari syndrome (BCS) complicated with liver cancer. Methods Clinical data of a BCS patient complicated with liver cancer undergoing transabdominal pericardial anastomosis of suprahepatic vena cava and right atrium in liver transplantation were retrospectively analyzed. Results The hepatic vein and suprahepatic vena cava were partially occluded in the patient. Liver transplantation was completed by transabdominal pericardial anastomosis of suprahepatic vena cava and right atrium with beating-heart. In addition, due to pathological changes of the recipient's hepatic artery, splenic artery of the recipient was cut off, distal ligation was performed, and the proximal end was reversed and anastomosed with the common hepatic artery of the donor liver, and the reconstruction of hepatic artery was completed. The surgery was successfully performed. At approximately postoperative 1 week, the function of the liver allograft was gradually restored to normal, and no major complications occurred. The patient was discharged at postoperative 25 d. No signs of BCS recurrence was reported after 8-month follow-up. Conclusions It is safe and feasible to treat BCS by liver transplantation with transabdominal pericardial anastomosis of suprahepatic vena cava and right atrium. BCS patients complicated with liver cancer obtain favorable prognosis.

ObjectiveTo achieve high-dimensional prediction of class imbalanced of adverse drug reaction（ADR） of traditional Chinese medicine（TCM） and to classify and identify risk factors affecting the occurrence of ADR based on the post-marketing safety data of TCM monitored centrally in real world hospitals. MethodThe ensemble clustering resampling combined with regularized Group Lasso regression was used to perform high-dimensional balancing of ADR class-imbalanced data， and then to integrate the balanced datasets to achieve ADR prediction and the risk factor identification by category. ResultA practical example study of the proposed method on a monitoring data of TCM injection performed that the accuracy of the ADR prediction， the prediction sensitivity， the prediction specificity and the area under receiver operating characteristic curve（AUC） were all above 0.8 on the test set. Meanwhile， 40 risk factors affecting the occurrence of ADR were screened out from total 600 high-dimensional variables. And the effect of risk factors on the occurrence of ADR was identified by classification weighting. The important risk factors were classified as follows：past history， medication information， name of combined drugs， disease status， number of combined drugs and personal data. ConclusionIn the real world data of rare ADR with a large amount of clinical variables， this paper realized accurate ADR prediction on high-dimensional and class imbalanced condition， and classified and identified the key risk factors and their clinical significance of categories， so as to provide risk early warning for clinical rational drug use and combined drug use， as well as scientific basis for reevaluation of safety of post-marketing TCM.

Objective:To explore the clinical value of super micro vascular imaging (SMI) in evaluating the microvascular perfusion of diabetes foot treated by tibial transverse bone transport.Methods:A retrospective study of 18 diabetic foot patients who underwent tibial transverse bone transport in the Second Hospital of Shanxi Medical University from May 2019 to December 2021 were analysed, including 12 males and 6 females, with an average age of 64.89±14.34 years (range, 30-90 years). All patients had varying degrees of foot ulcer. Before and after the operation, the blood vessels of the patient's lower leg and foot were examined. The display rate of low-velocity blood flow was compared between color Doppler flow imaging (CDFI) and SMI; the blood flow and vascular index at the beginning of the first dorsal metatarsal artery before and after operation under SMI were compared; the number and length of new blood vessels were also compared before and after operation.Results:All patients were followed up for at least 2 months. CDFI blood flow display rate was 73.6% (106/144), and SMI blood flow display rate was 80.6% (116/144), the difference was statistically significant (χ 2=4.68, P=0.031). Under SMI, the blood flow at the beginning of the first dorsal metatarsal artery on the affected side was measured before operation 3.38 (1.33, 7.56) ml/min, 1 week after operation 4.19(2.84, 11.48) ml/min and 1 month after operation 3.72 (2.52, 11.40) ml/min, with statistically significant difference (χ 2=9.46, P=0.009). There were statistically significant differences in blood flow at 1 week and 1 month after operation compared with that before operation ( P=0.033, P=0.003). The vascular index at the beginning of the first dorsal metatarsal artery on the affected side was 3.84±3.60, 6.51±4.92 and 6.82±5.36 before operation, 1 week and 1 month after operation, respectively, and the differences were statistically significant( F=4.35, P=0.031). The vascular index in the first week after operation was significantly higher than that before operation ( P=0.026). Up to the last follow-up, the number of new collaterals in 18 patients was 4.5 (2, 8), which was significantly different from 1 (0, 2) before operation ( Z=-3.57, P=0.001). In total, the length of 18 new blood vessels in 9 patients was longer than that before operation, and the establishment of grade 2 and grade 3 branches were observed in 5 patients. The superficial subcutaneous vessels were showed more clarity than that before surgery, and there was collateral circulation on the opposite side. Conclusion:SMI objectively reflects the changes of hemodynamics and microcirculation of patients after tibial transverse bone transport, and helps clinical preliminary predict the prognosis of patients and adjust individual treatment plan according to blood perfusion in time.

Objective:To investigate the correlation between food-specific IgG (sIgG) antibodies and phenotypes of chronic spontaneous urticaria (CSU) .Methods:Serum samples were collected from outpatients with active CSU, symptomatic dermographism (SD) , or acute urticaria (AU) , and healthy controls from 5 third-grade class-A hospitals such as the First Hospital of China Medical University between April 2014 and March 2015. Enzyme-linked immunosorbent assay was conducted to detect serum levels of 90 food-sIgG antibodies and total IgE, Western blot analysis to detect levels of 20 allergen-specific IgE antibodies, and chemiluminescent microparticle immunoassay to detect levels of anti-thyroid peroxidase IgG antibodies and anti-thyroglobulin IgG antibodies. Comparisons of normally distributed quantitative data between two groups and among several groups were performed by t test and one-way analysis of variance, respectively; comparisons of non-normally distributed quantitative data between two groups were performed by Mann-Whitney U test; for comparisons of proportions, chi-square test and Fisher′s exact test were used. Results:A total of 248 patients with CSU, 22 with SD, 15 with AU and 13 healthy controls were recruited. The cut-off level for sIgG positivity was 100 U/ml (at least 2+) , and the positive rate of food-sIgG antibodies was slightly higher in the patients with CSU (176/248, 70.97%) , SD (15/22, 68.18%) and AU (11/15) than in the healthy controls (7/13; χ2 = 1.80, P = 0.615) . Among the 248 CSU patients, the proportion of patients with family history of allergic diseases was significantly higher in the sIgG-positive group (71/176, 40.34%) than in the sIgG-negative group (19/72, 26.39%; χ2 = 4.30, P = 0.042) , while no significant difference was observed in the 1-day urticaria activity score (UASday) between the two groups ( Z = 0.18, P = 0.859) . Totally, 177 CSU patients completed 12- to 40-week treatment; their condition could be completely controlled by second-generation H1-antihistamines, and there was no significant difference in the required dosage of second-generation H1-antihistamines between the sIgG-positive group (128 cases) and sIgG-negative group (49 cases; Z = -1.06, P = 0.298) . Conclusions:The prevalence of family history of allergic diseases was relatively high in food-sIgG-positive patients with CSU. However, food-sIgG could not be used as an indicator to reflect the disease activity of CSU and treatment response.
