Master-apprentice education in traditional Chinese medicine （TCM） is an important approach for training TCM professionals. It compensates for the shortcomings of formal education， serves as a vivid practice of integrating Chinese traditional culture into TCM education， and is an effective pathway for cultivating high-level TCM talent. The implementation pathways for the innovative development of TCM master-apprentice education are as follows： fully utilizing the initiative of mentors and academic successors， innovating learning models that connect famous doctors and teachers， expanding master-apprentice model-based medical services to grassroots levels， integrating interdisciplinary， cross-border fields， and modern information technology with master-apprentice education， as well as promoting regular， systematic， and diversified theoretical learning. This approach aims to achieve innovative development of master-apprentice education in TCM under the background of the new era.

Objective To explore the influence of different hardness surfaces on gait coordination in patients with functional ankle instability(FAI). Methods Qualisys Infrared Optical Motion Capture System was used to test the coordination and variability of 15 FAI patients on the right side at Nanjing Normal University from May to July,2023.The gait cycle data were collect-ed and intercepted,and coupling angle(CA)and standard deviation of coupling angle(SDCA)were calculated by Matlab to compare the differences on different hardness surfaces. Results On coronal plane,CA of hip-ankle joint was higher on the hard surface than on the soft surface during middle stage of support and early stage of swing,and lower on its rest stages and the gait stages of hip-knee joint and knee-ankle joint than on the soft surface(P<0.01).On sagittal plane,CA of hip-ankle joint and knee-ankle joint was smaller on the hard surface than on the soft surface during middle and late stages of support,and larger than on the soft surface during their rest stages,and the gait stages of hip-knee joint(P<0.01).On horizontal plane,CA of hip-knee joint was lower on the hard surface than on the soft surface during the late stage of support,and higher than on the soft surface during its early stage of swing and bearing stage of hip-ankle joint(P<0.01).Compared with the hard surface,SDCA was smaller on the soft surface than on the hard surface only in the hip-ankle on the sagittal plane and during bearing stage of hip-knee joint,and was greater than on the hard surface for the rest(P<0.01). Conclusion FAI patients showed more distal dominance on soft surface than on hard surface during most gait cycle on 3D plane,i.e.,advantage of ankle varus and plantar flexion increased,and advantage of hip joint decreased;the coordination variability was generally higher on soft surface than on hard surface.These findings suggested that FAI patients may increase the risk of recurrent lateral ankle sprain walking on soft surface.

Objective To explore the intervention effect and molecular mechanism of Xinkang Granules on inflammatory factors in rats with chronic heart failure based on cGAS/STING signaling pathway.Methods SD rats were randomly divided into normal group and modeling group.The chronic heart failure model was established by intraperitoneal injection of Doxorubicin Hydrochloride.After successfully modeling,the rats were further divided into model group,Valsartan group and Xinkang Granules group.The model group was treated with distilled water every day,the Valsartan group was treated with Valsartan solution every day,and the Xinkang Granules group was treated with Xinkang Granules every day,all given for 4 consecutive weeks.Echocardiography was used to detect cardiac function,the pathological changes of myocardium were detected by hematoxylin-eosin staining(HE),the ultrastructural changes of myocardium in each group were observed by transmission electron microscope,and the contents of interleukin-1β(IL-1β)and interleukin-6(IL-6)in serum were detected by enzyme-linked immunosorbent assay(ELISA).The mRNA expression levels of mitochondrial transcription factor A(TFAM),cyclic guanosine monophosphate-adenylate synthase(cGAS),interferon-stimulated gene(STING)and IL-6 in myocardial tissue of rats in each group were detected by real-time fluorescence quantitative method(qPCR).The protein expressions of cGAS and STING in rat myocardial tissue were detected by immunohistochemical method.Results Compared with the blank group,the rats in the model group had significant inflammatory cell infiltration and inflammatory edema in myocardial tissue,their cardiac function was significantly reduced(P＜0.05,P＜0.01),and serum inflammatory factors were significantly increased(P＜0.01).The mRNA expression of TFAM in myocardial tissue was significantly reduced(P＜0.01),the mRNA expressions of IL-6,cGAS,and STING were significantly increased(P＜0.01),and the protein expressions of cGAS and STING in the myocardial tissue were significantly increased(P＜0.01).Compared with the model group,the cardiac function of the rats in the Xinkang Granules group was significantly improved(P＜0.05,P＜0.01),the inflammatory infiltration of myocardial cells was reduced,the expression of serum inflammatory factors was significantly reduced(P＜0.01),the mRNA expression of TFAM in myocardial tissue was significantly increased(P＜0.05),and the mRNA expressions of IL-6,cGAS,and STING were significantly decreased(P＜0.01),the protein expressions of cGAS and STING in myocardial tissue were significantly decreased(P＜0.01).Conclusion Xinkang Granules can reduce the expression of inflammatory factors and improve cardiac function in rats with chronic heart failure.Its mechanism may be related to inhibiting the cGAS/STING signaling pathway.

ObjectiveTo summarize and compare the main traditional Chinese medicine （TCM） syndromes of Delta and Omicron variants of severe acute respiratory syndrome coronavirus 2 （SARS-CoV-2） carriers to provide references for the syndrome evolution and syndrome differentiation of SARS-CoV-2 infection. MethodThe TCM medical records of imported and local cases of infection with Delta and Omicron variants of SARS-CoV-2 in Changsha since September 23， 2021 to March 27， 2022 were collected， including 18 Delta variant cases and 36 Omicron variant cases. Their TCM diagnosis information and TCM pathogenesis were analyzed and compared. ResultThe common manifestations in Delta variant cases were cough， fever， chest distress/shortness of breath， sore muscles， nausea， dry mouth， dry or sore throat， thick and greasy tongue coating， and rapid and slippery pulse. The predominant pathogenesis was dampness-heat in the upper-energizer and heat stagnation in the lesser Yang combined with dampness. The occurrence of chest distress/shortness of breath， greasy tongue coating， slippery pulse， and the proportion of dampness-heat in the upper-energizer syndrome were higher in Delta variant cases than in Omicron variant cases （P<0.05）. The common manifestations in Omicron variant cases were itchy and sore throat， nasal congestion， running nose， fever， mild aversion to cold， dry mouth， dizziness， slightly reddish tongue with thin white coating， and rapid or wiry pulse. The predominant pathogenesis was wind-dryness invading defensive exterior， and heat stagnation in the lesser Yang. The occurrence of white-coated tongue and the proportion of wind-dryness invading defensive exterior syndrome were higher in Omicron variant cases than in Delta variant cases （P<0.05）. ConclusionThere are certain differences in TCM syndromes and the corresponding pathogenesis between Delta variant and Omicron variant cases in Changsha， Hunan. The Delta variant of SARS-COV-2 tends to induce dampness-heat syndrome， whereas Omicron variant infection tends to elicit wind-dampness syndrome， which is expected to provide a reference for the pathogenesis evolution of SARS-COV-2 infection.

Background Occupational stress and depressive symptoms of disease prevention and control personnel are serious. Objective To investigate the relationship between occupational stress, psychological capital, and depressive symptoms of disease prevention and control personnel, and analyze the potential mediating effect of psychological capital on the relationship between occupational stress and depressive symptoms. Methods From July to September 2020, a cluster random sampling method was used to select 2201 employees from 21 centers for disease control and prevention as study subjects covering all levels of administrative divisions in Jiangsu Province. A total of 2036 valid questionnaires were collected with a recovery rate of 92.5%. The Core Occupational Stress Scale, Patient Health Questionnaire, and Psychological Capital Questionnaire were used to investigate their occupational stress, depressive symptoms, and psychological capital. Stratified regression analysis was used to explore the effects of occupational stress and psychological capital on depressive symptoms. A mediating effect model was used to analyze and verify the potential mediating effect of psychological capital on the relationship between occupational stress and depressive symptoms. Results The total scores in M (P₂₅, P₇₅) of occupational stress, depressive symptoms, and psychological capital in the target population were 42.0 (37.0, 48.0), 8.0 (4.0, 9.0), and 4.6 (4.0, 5.0) respectively. The positive rate of occupational stress was 31.0% (631/2036), and the positive rate of depressive symptoms was 22.0% (448/2036). The dimensional scores of organization and reward, and demand and effort of occupational stress were positively correlated with the total score of depressive symptoms [Spearman correlation coefficients (r_s) were 0.371 and 0.269, P<0.05]. The dimensional scores of social support and autonomy of occupational stress and the score of psychological capital were negatively correlated with the total score of depressive symptoms (r_s=−0.373, −0.112, −0.494, P<0.05). The organization and reward, and demand and effort had positive effects on depressive symptoms (b=0.188, 0.177, P<0.05), while social support and autonomy had negative effects on depressive symptoms (b=−0.290, −0.078, P<0.05), and associated with a 22.5% increase of explanatory variance. Psychological capital had a negative effect on depressive symptoms (b=−0.368, P<0.05), and associated with an 11.0% increase of explanatory variance. Psychological capital had mediating effects on the associations of social support, organization and reward, and autonomy with depressive symptoms, and the mediating effect values were −0.210 (95%CI: −0.253-−0.171), 0.096 (95%CI: 0.071-0.122), and −0.164 (95%CI: −0.229-−0.103), respectively. The corresponding mediating effect percentages were 40.23%, 26.97%, and 45.56%, respectively. Conclusion Occupational stress of disease prevention and control personnel can directly affect depressive symptoms, but also indirectly through psychological capital. Psychological capital plays a partial mediating role in the associations of social support, organization and reward, and autonomy of occupational stress with depressive symptoms. The occurrence of depressive symptoms can be reduced by decreasing occupational stress and increasing psychological capital.

As a group of nonspecific inflammatory diseases affecting the intestine, inflammatory bowel disease (IBD) exhibits the characteristics of chronic recurring inflammation, and was proven to be increasing in incidence (Kaplan, 2015). IBD induced by genetic background, environmental changes, immune functions, microbial composition, and toxin exposures (Sasson et al., 2021) primarily includes ulcerative colitis (UC) and Crohn's disease (CD) with complicated clinical symptoms featured by abdominal pain, diarrhea, and even blood in stools (Fan et al., 2021; Huang et al., 2021). UC is mainly limited to the rectum and the colon, while CD usually impacts the terminal ileum and colon in a discontinuous manner (Ordás et al., 2012; Panés and Rimola, 2017). In recent years, many studies have suggested the lack of effective measures in the diagnosis and treatment of IBD, prompting an urgent need for new strategies to understand the mechanisms of and offer promising therapies for IBD.

Objective To investigate the clinicopathological characteristics and independent risk factors of hepatocellular carcinoma (HCC) differentiation.  Methods A total of 108 HCC patients who underwent operation and treatment were reviewed and classified into low differentiation group (n= 29, 26.85%), medium differentiation group (n=53, 49.07%) and high differentiation group (n=26, 24.07%) according to pathological diagnosis. The clinicopathological characteristics and the expression levels of Ki67 and P53 in each group were compared and analyzed. Logistic regression model was used to analyze the risk factors for low differentiation of HCC.  Results The proportion of cirrhosis, the positive rate of P53 and Ki67 expression level in different degrees of HCC differentiation were statistically significant (P<0.05). However, there were no significant differences in age, sex, tumor diameter, and hepatitis virus infection or tumor involvement of liver capsule between groups (P>0.05). Multivariate logistic analysis showed that cirrhosis (OR=3.408), high expression of Ki67 (OR=11.113) and positive P53 (OR=9.711) were the main risk factors for poorly differentiated HCC.  Conclusion There are differences in clinical characteristics and expressions of Ki67 and P53 in HCC patients with different degrees of differentiation. Logistic regression analysis can identify clinicopathological risk factors affecting the degree of differentiation of HCC, which can provide criterion support for accurate diagnosis and prognostic treatment.

Objective: To compare the measurement accuracy of two⁃dimensional (2D) photography and three⁃di⁃mensional (3D) photography in the analysis of the asymmetric appearance of children with cleft lip and palate and the influence of the severity of asymmetric deformity on the accuracy of facial measurement to guide clinical measurement work Methods: Children with unilateral cleft lip were enrolled in this prospective study. Seven parameters⁃⁃the devia⁃tion of the pronasale, subnasale, and labrale superius, as well as the cleft/noncleft ratio of the width of nostrils, length and height of lateral lips and height of columella⁃were measured with Vernier calipers as the gold standard. Traditional 2D photography and 3D stereophotogrammetry photos were taken and measured. The extent of cleft malformation is indi⁃cated by the ratio of the cleft side to the noncleft side. The error size is represented by the ratio difference between two⁃dimensional photography or stereophotogrammetry with the ratio of the gold standard Results: Thirteen patients were eventually recruited. The measurement results of the ratio of lateral lip height by 2D photography tended to be larger (P＝0.019), and the measurement results of the ratio of columella height tended to be smaller (P＝0.008). The measure⁃ment results of the deviation of the subnasale by stereophotogrammetry tended to be smaller (P＝0.003). The pronasale deviation (P＝0.022) with two⁃dimensional photography, the deviation of the labrale superius (P＝0.025) and the ratio of lateral lip length (P＝0.036) with stereophotogrammetry had a significant negative correlation with the extent of cleft malformation Conclusion Both two⁃dimensional photography and stereophotogrammetry have errors and biases that underexaggerate or overexaggerate the extent of cleft malformation, and some errors may increase with the decrease in the extent of cleft malformation. When applying two⁃dimensional and three⁃dimensional photography to analyze cleft lip and palate deformities, these biases should be considered to evaluate the face more objectively

To investigate the expression of microRNA-34a (miR-34a) in patients with chronic lymphocytic leukemia (CLL) in Xinjiang Uygur and Han nationalities and its prognostic significance. Our data showed that miR-34a expression in Uygur and Han CLL patients was significantly higher than that in their respective healthy controls, while miR-34a levels were similar between Uygur and Han patients. By comparing with known prognostic factors, receiver operating characteristic (ROC) curves showed that miR-34a was a good predictive factor for the prognosis of CLL (demarcation value was 3.567 6). Survival analysis was further performed according to miR-34a expression level, that low expression of miR-34a translated into poor prognosis.

Background and purpose: With the application of laparoscopy in the liver surgery increasingly widely used, the safety and feasibility of laparoscopic liver resection is gaining recognition gradually. This study aimed to explore the laparoscopic liver resection for the tumor and the feasibility of open liver tumor resection and clinical curative effect. Methods: We retrospectively analysed the clinical data from 37 cases of laparoscopic hepatectomy and 74 patients with open liver resection from Mar. 2015 to Mar. 2016. Measurement data by covariance analysis were obtained, and comparison between groups were made using independent sample with Wilcoxon rank test and statistical value of Z. We collected data including operation time, intra-operative blood loss, post-operative recovery time of gastrointestinal tract, surgical drainage tube after extubation time, length of hospital stay, postoperative complications, hospitalization expenses and other clinical data. Laparoscopic group had 20 males and 17 female aged 18 to 76 (median age 55). Open group had 42 males and 32 females aged 26 to 74 (median age 54). The hepatectomy included ultrasonic knife + unipolar electric coagulation, combined with laparoscopic incision suture. Surgery procedures included 13 cases of local excision in laparoscopic group and 24 cases of liver segment or lobe anatomical resection. Open group had 33 cases of local excision and 41 cases of liver segment or lobe anatomical resection. Results: The average duration of laparoscopic hepatectomy was 149 min (40-204 min). The average duration of open hepatectomy was 142 min (45-190 min). The average intra-operative blood loss was 220 mL (30-570 mL) in laparoscopic group and 360 mL (90-970 mL) in open group. The average length of hospital stay was 4.9 d (3-6 d) in laparoscopic group and 6.8 d (5-9 d) in open group. Gastrointestinal average recovery time was 1.1 days in laparoscopic group and 2.3 days in open group. The average hospitalization expenses were 38760 yuan in laparoscopic group and 39145 yuan in open group. Conclusion:Laparoscopic hepatectomy is a safe, effective and minimally invasive surgery, can be safely used in local, liver segment and half liver resection, worthy of promotion.
