By aggregating the essence of theories related with depressive syndrome from historical medical practitioners and based on the extensive clinical experience,traditional Chinese medicine(TCM)master Lin Yi proposed the theory of six-stagnation-based breast disease prevention and treatment.She pointed out that the occurrence of breast diseases is related to six stagnations(qi stagnancy,blood stagnancy,phlegm stagnancy,dampness stagnancy,food stagnancy,and fire stagnancy),and the treatment for breast diseases should start from the six stagnations.The development and progression of breast cancer is closely associated with the imbalance of internal environment and the formation of six stagnations,and breast cancer is one of the major diseases suitable for the TCM syndrome differentiation and treatment.For the treatment of early breast cancer,Professor Lin Yi proposed to divide early breast cancer into four stages,namely perioperative period,peri-chemotherapy period,peri-radiotherapy period,and consolidation period.Guided by the theory of six-stagnation-based breast disease prevention and treatment,therapies of soothing the liver,resolving phlegm,removing stasis,clearing heat,eliminating dampness,promoting digestion,fortifying the spleen,and tonifying the kidney are employed to harmonize the internal environment and alleviate symptoms.The theory of six-stagnation-based breast disease prevention and treatment enriches the TCM theory for the prevention and treatment of breast cancer,refines the principles and methods for the staging and syndrome differentiation of early breast cancer,and holds significant implications for enhancing the efficacy of integrated TCM and western medicine in managing early breast cancer.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

In order to explore the relationship between ubiquitin proteasome system(UPS)and au-tophagy after macrophage was infected with Brucella.On the one hand,the levels of LC3 Ⅱ、P62 and 20S proteasomes in cell supernatant and peritoneal fluid were determined respectively after RAW264.7 cells were infected and BALB/c mice were intraperitoneal inoculated with Brucella suis(B.suis).The results displayed that UPS was activated firstly,followed by autophagy after B.suis infection.On the other hand,we prepared the UPS-inhibited-cells and ALP-inhibited-cells by lacta-cystin and 3-methy ladenine(3-MA),and then the cells were infected by B.suis and the levels of LC3 Ⅱ、P62 与 20S proteasomes in cell supernatant were determined.The results showed that the ALP function was significantly improved when the effect of M

Objective:To explore the spatial and temporal distribution patterns of emerging snail-infested sites in different environmental types in Yunnan Province.Methods:The data of snail-infested sites in Yunnan Province from 1950 to 2014 (from Yunnan Institute for Endemic Diseases Control and Prevention), were collected and sorted out, a spatial and temporal database on the distribution of emerging snail-infested sites were established, and the changes in the spatial and temporal distribution of emerging snail-infested sites in different environments types (ditches, tangerines, paddy fields, dry land, beaches and other environments) were studied by using spatial autocorrelation analysis and scanning statistics analysis.Results:From 1950 to 2014, the annual number of emerging snail-infested sites in Yunnan Province reached a peak (1 730) in 1955 and then showed a fluctuating downward trend. From 1993 to 2014, the number of emerging snail-infested sites remained below 100, and increased to 160 and 131, respectively, in 2004 and 2013. The longest mean duration of 43.85 years was recorded for the beaches environment for emerging snail-infested sites, followed by the paddy fields environment with a mean duration of 37.01 years, and the shortest mean duration of 20.44 years for the tangerines environment. Spatial autocorrelation analysis showed that there was a positive spatial correlation between the duration of emerging snail-infested sites of different environmental types (global Moran's I ranged from 0.43 to 0.64, P < 0.05). Scanning statistics analysis showed that emerging snail-infested sites of different environmental types had spatial and temporal aggregation ( P < 0.001), with 3- 6 clusters of statistically significant aggregation detected respectively. Conclusion:The emerging snail-infested sites in different environments types in Yunnan Province have spatial and temporal aggregation, and it is necessary to strengthen monitoring and prevention and control of the aggregation areas of different environment types to prevent further spread of the snail.

In recent years, the corona virus disease 2019 (COVID-19) pandemic has had a huge impact on the global medical, political and economic fields. Since the beginning of the COVID-19 epidemic, our understanding of the impact of COVID-19 has grown exponentially. Recently, the COVID-19 epidemic has changed rapidly in China, and there has been controversy over how to carry out surgical operations for patients with lung neoplastic lesions. Some studies have shown that lung cancer patients undergoing surgery are more likely to experience respiratory failure and perioperative death after contracting COVID-19 than the general population, however, delays in cancer treatment are also associated with increased mortality among these patients. In particular, the novel coronavirus Omikron variant has a higher transmissibility and may escape the immunity obtained through the previous novel coronavirus infection and vaccination. In order to minimize the risk of novel coronavirus infection in surgical patients, it is necessary to develop new treatment guidelines, expert consensus and preventive measures. However, the current rapid change of the epidemic situation has led to insufficient time and evidence to develop guidelines and consensus. Therefore, thoracic surgeons need to evaluate specific patient populations at higher risk of severe complications before surgery and weigh the benefit of surgical treatment against the risk of novel coronavirus infection. We try to give some recommendations on lung surgery during the current domestic epidemic situation based on the guidelines and consensus of oncology and thoracic surgery organizations in different regions on lung surgery.

Objective:To compare left and right ventricular Tei indexes and to determine the reference range in newborns of different gestational age (GA) and birth weight (BW).Methods:From February 2019 to June 2021, newborns admitted to the Neonatal Intensive Care Unit of our hospital were enrolled. Tei indexes were measured and calculated during 24 h~7 d after birth and reexamined 1~2 weeks later in some of the newborns. The newborns were assigned into <32 w group, 32~36 w group and ≥ 37 w group according to their GA, < 1 500 g group, 1 500~2 499 g group and ≥2 500 g group according to their BW, and early newborn group (1~7 d) and late newborn group (>7 d) according to their age of evaluation. The data were analyzed using t test, one-way analysis of variance (ANOVA) and correlation analysis with SPSS 20.0 statistical software. Results:A total of 128 cases were included. 42 cases in <32 w group, 43 in 32~36 w group and 43 in ≥37 w group. 42 cases in <1 500 g group, 42 in 1 500 ~ 2 499 g group and 44 in ≥2 500 g group. Tei indexes were reexamined after 7 d of age in 63 preterm infants and in 31 full-term infants. The left and right ventricular Tei indexes of the ≥37 w group were less than the 32~36 w group and the <32 w group in early newborns (left ventricular: 0.382±0.069 vs. 0.431±0.069 and 0.439±0.060, right ventricular: 0.373±0.038 vs. 0.431±0.035 and 0.452±0.064); the right ventricular Tei index of the 32~36 w group was significantly less than the <32 w group ( P<0.05). No significant differences existed in the left ventricular Tei index between the 32 ~ 36 w group and the < 32 w group ( P>0.05). The left and right ventricular Tei indexes of the ≥2 500 g group were significantly less than the 1 500~2 499 g group and the <1 500 g group (left ventricular: 0.385±0.069 vs. 0.434±0.067 and 0.434±0.064, right ventricular: 0.376±0.039 vs. 0.431±0.043 and 0.450±0.061) ( P<0.05).No significant differences existed between the 1 500~2 499 g group and the <1 500 g group ( P>0.05). No significant differences existed in the left and right ventricular Tei indexes between the late newborn group and early newborn group ( P>0.05). For early newborns (1~7 d of age), the reference range of Tei index gradually decreased along with the increase of GA and BW. Conclusions:The left and right ventricular Tei indexes of full-term infants and infants with BW ≥2 500 g are less than preterm and low birth weight infants. The reference range of Tei index in early newborns shows negative correlation with GA and BW.

Objective To evaluate the efficacy of tinnitus retraining therapy (TRT) on anxiety , depression , and symptoms of sleep disorders in patients with chronic subjective tinnitus. Methods Eighty patients with chronic subjective tinnitus visiting The Affiliated Hospital of Hangzhou Normal University from January 2016 to December 2017 were recruited ,and were divided into an observation group and a control group through computer generated random numbers. Patients in the control group were given drug treatment only ,while those in the observation group received TRT in addition to drug treatment. Clinical efficacy was evaluated using Tinnitus Handicap Inventory (THI) , Pittsburgh Sleep Quality Index (PSQI) ,Hamilton Depression Scale (SDS) ,and Hamilton Anxiety Scale (SAS ) for both groups. Results Patients in the observation group were associated with significantly lower scores of THI ,PSQI ,SAS and SDS ,compared with those in the control group 3 months after treatment (each P＜0.05). Furthermore ,the effectiveness rate was markedly higher (82.5% or 33 cases vs. 55.0% or 22 cases ,χ2＝7.040 ,P＜0.01) in the observation group than in the control group 6 months after treatment. Conclusion Tinnitus retraining therapy combined with conventional therapy can help to reduce the severity of tinnitus handicap ,ameliorate negative emotions such as anxiety and depression ,and improve sleep quality in patients with chronic subjective tinnitus.

Objective To investigate the protective effect of augmenter of liver regeneration (ALR) against acute liver injury and related mechanisms.Methods HL-7702 cells were divided into normal control group,carbon tetrachloride (CCl4)-induced acute liver injury group,ALR+CCl4 intervention group,3-methyladerine (3-MA)+CCl4 intervention group,and ALR+3-MA+CCl4 intervention group.The ALR+CCl4 and ALR+3-MA+CCl4 intervention groups were transfected with ALR plasmids at 8 hours before CCl4 treatment.All groups except the normal control group were treated with CC14,and 30 minutes later,the 3-MA+CC14 and ALR+3-MA+CCl4 intervention groups were treated with 3-MA.The cells were collected at 24 hours after CCl4 treatment.The HL-7702 cells and supematant were collected to measure the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (IU/L).Westem blot was used to measure the levels ofALR,cyclin D,cyclin E,proliferating cell nuclear antigen (PCNA),autophagy-related gene 7 (Atg7),and autophagy genes LC3,p62,and Beclin-1.Quantitative real-time PCR was used to measure the mRNA expression ofALR.A oneway analysis of variance was used for comparison of means between any two groups.Results The ALR+CCl4 intervention group had significant increases in the protein and mRNA expression of ALR compared with the acute liver injury group (both P ＜ 0.05).The CC14-induced acute liver injury group had significant increases in the protein and mRNA expression of ALR compared with the normal control group (both P ＜ 0.05).Compared with the CCl4-induced acute liver injury group,the ALR+CCl4 intervention group had significant reductions in ALT (0.73±0.17 IU/L vs 1.43±0.38 IU/L,P ＜ 0.05) and AST (19.85±1.83 IU/L vs 56.73±6.25 IU/L,P ＜ 0.05) in supematant,significantly increased expression of cyclin D,cyclin E,PCNA,LC3,Atg7,and Beclin-1 in hepatocytes,and significantly reduced expression of p62,which suggested that ALR protected the liver against acute liver injury,promoted the regeneration of hepatocytes,and enhanced the autophagy of hepatocytes.The ALR+3-MA+CCl4 intervention group had a significant reduction in the expression of regeneration-associated proteins compared with the ALR+CCl4 intervention group,while there was no significant difference between the ALR+3-MA+CCL4 intervention group and 3-MA+CCL4 intervention group,which suggested that after the inhibition of autophagy,there were significant reductions in the regeneration of hepatocytes and liver regeneration promoted by ALR.Conclusion ALR can promote the regeneration of hepatocytes in liver parenchyma,which is achieved by the regulation of autophagy.
