This article summarized clinical experience in differentiating and treating non-obstructive hypertrophic cardiomyopathy （HCM） based on the concept of nourishing the heart and softening the hardness. It is considered that HCM belongs to the category of "heart accumulation"， with the fundamental cause being depletion of the spleen and kidney， and phlegm-stasis accumulation， as well as qi-yin exhaustion， serving as the manifestations. Spleen and kidney depletion leads to the transformation of phlegm and stasis， which accumulate in the heart； over time， this phlegm-stasis accumulation consumes heart qi and yin， resulting in the heart being deprived of nourishment， which eventually leads to the damage to both the function and structure of heart. Therefore， the method of nourishing the heart and softening the hardness is proposed for the treatment of non-obstructive HCM. Emphasis is placed on softening hardness and dissipating masses throughout the entire treatment process， often using Modified Siwei Ruanjian Formula （四味软坚方加减）. During periods with prominent symptoms， the main treatment is boosting qi and nourishing yin to soften hardness and dissipate masses with self-made Yuxin Ruanjian Formula （自拟育心软坚方） in modifications； in stable periods， the main treatment is boosting kidney and fortifying spleen to soften hardness and dissipate masses with self-made Pishen Tongzhi Formula （脾肾同治方） in modifications.

The tumor microenvironment includes blood vessels， lymph， nerves， non-malignant cells， and their metabolites at and near the tumor lesion site， which interact with cancer cells and promote cancer progression. Rapid proliferation of cancer cells increases oxygen consumption， or abnormalities in the structure and function of blood vessels in solid tumors lead to a decrease in oxygen supply， forming a hypoxia microenvironment. The existence of a hypoxia microenvironment is a typical pathophysiological feature of locally advanced solid tumors， widely present in various types of human malignant tumors. Hypoxia microenvironment is a sign of tumor microenvironment and an important and complex system in the breast tumor microenvironment. Its formation and development are closely related to the growth of breast cancer， occupying an important position in the research and treatment of breast cancer. With its advantages of multiple pathways and multiple targets， the effective monomer and compound of traditional Chinese medicine can better regulate the hypoxia microenvironment of breast cancer， inhibit the proliferation， invasion， and metastasis of breast cancer cells in the hypoxia environment， induce apoptosis， reverse their drug resistance， intervene in the metabolic reprogramming of breast cancer cells in the hypoxia environment， and inhibit their angiogenesis， thereby improving the quality of life of patients to a certain extent and prolonging the survival cycle of patients. This paper first summarized and discussed the effects of hypoxia microenvironment on proliferation， invasion， metastasis， drug resistance， immune function， metabolic reprogramming， non-coding RNA， iron death， and autophagy of breast cancer cells， which affected the occurrence and development of breast cancer， and it elaborated the mechanism behind it. Then， the paper elucidated the regulatory effect and mechanism of targeting the hypoxia microenvironment based on the two modes of effective monomer and compound of traditional Chinese medicine， so as to analyze and extract the deficiencies and directions of traditional Chinese medicine in regulating the hypoxia microenvironment and provide a theoretical reference for the effective treatment of breast cancer.

Objective:To explore the value of serum matrix metalloproteinase-1 (matrix metalloproteinase-1), and phosphatase and tensin hmmlogydeleted on ten (PTEN), in predicting osteoporosis (OP) in women with gestational diabetes mellitus (GDM) .Methods:The clinical data of.218 pregnant women with GDM treated in Linyi People’s Hospital from Sep. 2019 to Feb. 2023 were retrospectively collected and included in the GDM group. Another 98 healthy pregnant women who underwent physical examination during the same period were selected as the control group. Age, body mass index (BMI), blood glucose related indexes and serum MMP-1 and PTEN levels were compared between the two groups. According to the occurrence of osteoporosis (OP) in the second and third trimester of pregnancy, the GDM group was divided into OP group and non-OP group. Logistic regression analysis was used to explore the influencing factors of OP in pregnant women with GDM in the second and third trimesters. ROC curve was drawn to analyze the predictive value of serum MMP-1 and PTEN levels for osteoporosis in GDM pregnant women in the second and third trimesters.Results:Body mass index (BMI), fasting blood glucose (FBG), glycated hemoglobin A1c (HbA1c) and serum MMP-1 and PTEN levels in GDM group were higher than those in control group, but BUA, SOS and SI were lower than those in control group ( t=6.18, 12.68, 9.91, 11.42, 7.70, 5.63, 5.76, 9.84, all P<0.05). Among 218 GDM women, 29 cases had OP and 189 cases did not have OP. There were no significant differences in fasting blood glucose, glycosylated hemoglobin, blood calcium, blood magnesium, or blood phosphorus between the two groups (statistical value: 0.96, 0.86, 1.35, 1.06, 0.49, P>0.05). Logistic regression analysis showed that age, abnormal increase of MMP-1 and PTEN levels were independent risk factors for OP in GDM women in the second and third trimesters [ OR (95% CI) =1.260 (1.103-1.440) ,1.075 (1.031-1.120) ,1.055 (1.023-1.089), all P<0.05]. ROC curve showed that the AUC of MMP-1 and PTEN in predicting OP in GDM pregnant women in the second and third trimesters were 0.824 and 0.777, respectively. The AUC of the combination of the two in predicting OP in GDM pregnant women in the second and third trimesters was 0.933, and the specificity and sensitivity were 83.04% and 93.48%, respectively, which were higher than those of single detection. Conclusions:MMP-1 and PTEN in early pregnancy may play a potential role in the prediction of OP in pregnant women with GDM. Close monitoring of MMP-1 and PTEN levels may provide new ideas for the clinical diagnosis and treatment of OP high-risk patients.

Objective To describe the status and influencing factors of psychological distress in older people living with HIV in Shanghai.Methods Convenience sampling was used to select HIV patients with the age of 50 years old and above who attended follow-up visits at the voluntary counselling & testing clinic in Shanghai Public Health Clinical Center from December 2022 to October 2023.Data were collected using a general information questionnaire,HIV disclosure questionnaire,Distress Thermometer and Lubben Social Network Scale-6.Binary logistic regression was employed to analyze the factors influencing psychological distress.Results The prevalence of psychological distress among 332 participants was 105 cases(31.6％).The top 3 items selected by participants in Psychological Distress Problem List were insurance/financial issues,worry and sleep,relationship with children.Factors associated with a higher level of psychological distress included lower monthly income,not HIV disclosure and higher levels of social isolation.Conclusion Psychological distress among older people living with HIV remains to be further reduced,and it is affected by many factors.Health care providers should pay more attention to psychological distress among older HIV patients,and develop targeted intervention according to relevant influencing factors,aiming to reduce their psychological distress.

Objective To investigate the neuroprotective effect and mechanism of salvia polyphenolic acid for injection (SAFI) on cerebral ischemia-reperfusion injury in rats. Methods A total of 100 SD rats were randomly divided into sham surgery group,model group,low-,medium-and high-dose (5,10,20 mg·kg-1) salvia polyphenolic acid groups,with 20 rats in each group. After being continuously administrated by intraperitoneal injection of SAFI once daily for three days,the rat model of middle cerebral artery occlusion/reperfusion (MCAO/R) was established using the thread embolization method at 1 hour after the last administration. The neurological deficit of rats was evaluated by Zea Longa score. The cerebral infarction volume was detected by 2,3,5-triphenyltetrazolium chloride(TTC) staining. The levels of serum NADPH oxidase(NOX),4-hydroxynonanal(4-HNE),8-hydroxydeoxyguanosine (8-OHdG),monocyte chemoattractant protein-1 (MCP-1),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),interleukin-18(IL-18),interleukin-6(IL-6),and intercellular adhesion molecule-1 (ICAM-1) were detected by ELISA kits. Hematoxylin-eosin (HE) staining and Nissl staining were used to observe the pathological changes of brain tissue and the morphology of neurons. The apoptosis of neuronal cells in brain tissue was detected by TUNEL. Immunofluorescence staining was used to detect the expression level of glial fibrillary acidic protein (GFAP) in brain tissue. Western Blot was used to detect the protein expression of NLRP3 and Caspase1 in brain tissue. Results Compared with the sham surgery group,neurological deficit scores in model group increased remarkably (P<0.01). The cerebral infarction volume increased significantly (P<0.01). Serious pathological damage of brain was observed,and neuronal density decreased significantly(P<0.01). The apoptosis rate of cortical cells increased obviously (P<0.01). The levels of serum NOX,4-HNE,8-OHdG,MCP-1,TNF-α,IL-1β,IL-18,IL-6 and ICAM-1 increased significantly (P<0.05,P<0.01). The protein expression of GFAP,NLRP3 and Caspase1 in brain significantly upregulated (P<0.01). Compared with the model group,neurological deficit scores in medium-and high-dose SAFI groups decreased remarkably (P<0.01). The cerebral infarction volume decreased significantly (P<0.01). Neuronal damage was ameliorated to varying degrees,and neuronal density increased significantly(P<0.05,P<0.01). The apoptosis rate of cortical cells decreased obviously (P<0.01). The levels of serum NOX,4-HNE,8-OHdG,MCP-1,TNF-α,IL-1β,IL-18,IL-6 and ICAM-1 decreased significantly (P<0.05,P<0.01). The protein expression of GFAP,NLRP3 and Caspase1 in brain significantly downregulated(P<0.01). Conclusion SAFI has a protective effect on MCAO/R rats,which can significantly reduce oxidative stress and inflammatory responses,thereby reducing pathological damage and apoptosis of brain tissue. Its mechanism may be related to the inhibition of NLRP3/Caspase-1 signaling pathway and astrocyte activation.

Tumor has become the major reasons cause of death,and its vaccine has become the effective tracts of treatment and prevention by enhancing the immune response of patients.However,most vaccines which are recombination subunit protein antigens are poorly immunogenic and difficult to induce a robust immune response in patients with compromised immune systems,resulting in poor marketing approval.The core component of the vaccine adjuvant can greatly enhance the strength,speed and duration of the immune response,thus becoming the key to the development of an ideal tumor vaccine.Most tumor vaccines are combined with tradition adjuvant such as aluminum,MF59 and AS adjuvant,but their products and patents are monopolized by large foreign companies.We found that natural adjuvants have many unique advantages,such as good biocompatibility and biodegradability,promoting the maturation of dendritic cell and the secretion of immune cytokines,significantly enhancing the tumor vaccine immune response,etc.In this paper,the application and future development of natural polysaccharides,saponins,flavonoid and plant virus-like particles in cancer vaccines were reviewed,which may lay a solid foundation for the development of the original and innovative adjuvants with domestic independent intellectual property rights.

Objectives:To explore obesity prevalence and its association with dietary patterns among Tibetan pastoralists during the urbanization transition in Qinghai Province.Methods:Using an open cohort study design, 1 003 subjects were enrolled at baseline in 2018, 599 were followed up, and 1 012 were newly recruited in 2022. A total of 1 913 adults over 18 years were included in the study, and a questionnaire survey and health examination were conducted. Factor analysis was used to identify dietary patterns, and a mixed-effects model was used to analyze the association between dietary patterns and obesity.Results:From 2018 to 2022, the prevalence rates of overweight, obesity, and central obesity were 27.6%, 33.8%, and 54.6%, respectively. Age-sex-standardized prevalence of obesity and central obesity increased. Three dietary patterns were identified: the modern pattern was characterized by frequent consumption of pork, poultry, processed meat, fresh fruits, sugary drinks, salty snacks, etcetera; the urban pattern was characterized by frequent consumption of refined carbohydrates, beef and mutton, vegetables and eggs, etcetera; and pastoral pattern featured frequent consumption of tsamba, Tibetan cheese, buttered/milk tea, and whole-fat dairy products. After adjusting for demographic characteristics, socioeconomic status, and lifestyle factors, compared with the T1, subjects in the T3 of urban pattern scores were more likely to be overweight ( OR=2.09, 95% CI: 1.10-3.95) and overweight/obese ( OR=1.23, 95% CI: 1.00-1.51), whereas those in the T3 of pastoral pattern scores had a lower risk of overweight ( OR=0.45, 95% CI: 0.24-0.84), obesity ( OR=0.81, 95% CI: 0.69-0.95), overweight/obesity ( OR=0.75, 95% CI: 0.61-0.91) and central obesity ( OR=0.58, 95% CI: 0.38-0.89). Conclusions:Prevalence of obesity and central obesity was high among Tibetan pastoralists during the urbanization transition. Urban dietary pattern was a risk factor for overweight and overweight/obesity, whereas pastoral dietary pattern was a protective factor for overweight, obesity, overweight/obesity, and central obesity. Tailored interventions are needed to improve local people's health.

Objective:To investigate the incidence and clinical characteristics of renal involvement with Omicron coronavirus infection in age-based stratified patients.Methods:The first batch of 430 convalescent patients with Omicron coronavirus treated in Tianjin First Central Hospital from January 21, 2022 to March 7, 2022 were enrolled in this study. The baseline information, vaccination status and laboratory examination information of patients were extracted in order to analyze the incidence of renal involvement in age-based stratified patients. Multivariate Logistic regression analysis was conducted to determine the risk factors of renal involvement in different age groups.Results:Excluding those younger than 1 year old and those with a history of chronic kidney disease, a total of 421 patients were included. There were 184 males and 237 females with an average age of (36.65±21.28) years. The types of renal involvement included pathological tubular urine (28.9%), proteinuria (16.9%), renal hematuria (14.7%), a slight decrease of estimated glomerular filtration rate (eGFR, 9.3%), renal glycosuria (0.5%). According to their age, all patients were divided into three groups: 113 cases of ≤ 18 years old, 244 cases of 19-59 years old and 64 cases of ≥ 60 years old. Significant difference was founded in the incidence of renal involvement among the three groups. The incidence of proteinuria, pathological tubular urine and slight decline of eGFR in the ≥ 60 years old group were significantly higher than those in the ≤ 18 years old group [28.1% (18/64) vs. 8.0% (9/112), 42.2% (27/64) vs. 19.6% (22/112), 34.9% (22/63) vs. 6.2% (7/113), respectively, all P < 0.01]. The incidence of slight decline of eGFR was significantly higher than that in 19-59 years old group [34.9% (22/63) vs. 4.1% (10/243), P < 0.01]. Multivariate Logistic regression analysis showed that age was significantly correlated with renal involvement after adjusting for the baseline situation, serological indexes and Omicron infection related indexes [odds ratio ( OR) = 1.059, 95% confidence interval (95% CI) was 1.021-1.097, P = 0.002]. Compared with the group ≤ 18 years old, the risk of renal involvement in the group ≥ 60 years old was significantly increased ( OR = 26.245, 95% CI was 1.357-507.458, P = 0.031). Age ≥ 60 years old was an independent risk factor for renal involvement with Omicron coronavirus infection. Conclusions:Although a low incidence of severe cases in Tianjin first batch of 430 patients with Omicron coronavirus infection, there is still a high incidence of renal involvement. Advanced age is the risk factor of renal involvement. We should pay more attention to the renal involvement of elderly with Omicron coronavirus infection.
