RESUMO

ObjectiveTo systematically evaluate the distribution of traditional Chinese medicine(TCM) syndromes of primary osteoporosis(POP) in China by using evidence-based medicine methods, and to understand the distribution law of the syndromes. MethodChina National Knowledge Infrastructure(CNKI), VIP Chinese Science and Technology Journal Database(VIP), WanFang Data Knowledge Service Platform(WanFang) and China Biology Medicine(CBM) were searched to obtain representative literature, and each database was searched from the 1994 World Health Organization defined diagnostic criteria for osteoporosis until May 1, 2023. Two researchers independently screened literature according to the criteria, extracted data, and cross-checked them. Meta analysis was conducted using R4.1.3, and subgroup analysis was performed. ResultA total of 56 Chinese papers were included, involving 14 415 patients. After standardized classification of syndromes, 11 articles were excluded, and Meta analysis results of the ultimately included 45 Chinese articles showed that the distribution frequencies of liver-kidney Yin deficiency syndrome, spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome in 12 723 patients were 27%[95% confidence interval(CI) 0.24-0.31], 32%(95% CI 0.29-0.36), 36%(95% CI 0.30-0.42). Subgroup analysis showed that there was a statistically significant difference in the distribution of the three TCM syndromes in the north and south(P<0.05). In addition, the incidence of TCM syndrome fractures in different types of POP was 15%(95% CI 0.09-0.24) for liver-kidney Yin deficiency syndrome, 20%(95% CI 0.12-0.30) for spleen-kidney Yang deficiency syndrome, and 31%(95% CI 0.25-0.39) for kidney deficiency and blood stasis syndrome. ConclusionThe distribution of syndromes in POP patients is mainly kidney deficiency, accompanied by liver and spleen dysfunction. Liver-kidney Yin deficiency syndrome, spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome are all the main syndromes of POP and osteoporotic fractures, and kidney deficiency and blood stasis syndrome is most closely related to the development of osteoporotic fractures. The reference standards for syndrome determination among the included studies are inconsistent, and in the future, it is necessary to focus on their determination standards to obtain consensus research results, at the same time, conduct large-scale syndrome research to obtain representative research results, providing a basis for clinical practice and research.

RESUMO

Objective To investigate the capillarization of liver sinusoidal endothelial cells (LSECs) and its association with hepatic fibrosis during the development of alveolar echinococcosis, so as to provide the basis for unraveling the mechanisms underlying the role of LSEC in the development and prognosis of hepatic injuries and hepatic fibrosis caused by alveolar echinococcosis. Methods Forty C57BL/6 mice at ages of 6 to 8 weeks were randomly divided into a control group and 1-, 2- and 4-week infection groups, of 10 mice in each group. Each mouse in the infection groups was intraperitoneally injected with 2 000 Echinococcus multilocularis protoscoleces, while each mouse in the control group was given an equal volume of phosphate-buffered saline using the same method. All mice were sacrificed 1, 2 and 4 weeks post-infection and mouse livers were collected. The pathological changes of livers were observed using hematoxylin-eosin (HE) staining, and hepatic fibrosis was evaluated through semi-quantitative analysis of Masson’s trichrome staining-positive areas. The activation of hepatic stellate cells (HSCs) and extracellular matrix (ECM) deposition were examined using immunohistochemical staining of α-smooth muscle actin (α-SMA) and collagen type I alpha 1 (COL1A1), and the fenestrations on the surface of LSECs were observed using scanning electron microscopy. Primary LSECs were isolated from mouse livers, and the mRNA expression of LSEC marker genes Stabilin-1, Stabilin-2, Ehd3, CD209b, GATA4 and Maf was quantified using real-time fluorescence quantitative PCR (qPCR) assay. Results Destruction of local liver lobular structure was observed in mice 2 weeks post-infection with E. multilocularis protoscoleces, and hydatid cysts, which were surrounded by granulomatous tissues, were found in mouse livers 4 weeks post-infection. Semi-quantitative analysis of Masson’s trichrome staining showed a significant difference in the proportion of collagen fiber contents in mouse livers among the four groups (F = 26.060, P < 0.001), and a higher proportion of collagen fiber contents was detected in mouse livers in the 4-week infection group [(11.29 ± 2.58)%] than in the control group (P < 0.001). Immunohistochemical staining revealed activation of a few HSCs and ECM deposition in mouse livers 1 and 2 weeks post-infection, and abundant brown-yellow stained α-SMA and COL1A1 were deposited in the lesion areas in mouse livers 4 weeks post-infection, which spread to surrounding tissues. Semi-quantitative analysis revealed significant differences in α-SMA (F = 7.667, P < 0.05) and COL1A1 expression (F = 6.530, P < 0.05) in mouse levers among the four groups, with higher α-SMA [(7.13 ± 3.68)%] and COL1A1 expression [(13.18 ± 7.20)%] quantified in mouse livers in the 4-week infection group than in the control group (both P values < 0.05). Scanning electron microscopy revealed significant differences in the fenestration frequency (F = 37.730, P < 0.001) and porosity (F = 16.010, P < 0.001) on the surface of mouse LSECs among the four groups, and reduced fenestration frequency and porosity were observed in the 1-[(1.22 ± 0.48)/μm2 and [(3.05 ± 0.91)%] and 2-week infection groups [(3.47 ± 0.10)/μm2 and (7.57 ± 0.23)%] groups than in the control group (all P values < 0.001). There was a significant difference in the average fenestration diameter on the surface of mouse LSECs among the four groups (F = 15.330, P < 0.001), and larger average fenestration diameters were measured in the 1-[(180.80 ± 16.42) nm] and 2-week infection groups [(161.70 ± 3.85) nm] than in the control group (both P values < 0.05). In addition, there were significant differences among the four groups in terms of Stabilin-1 (F = 153.100, P < 0.001), Stabilin-2 (F = 57.010, P < 0.001), Ehd3 (F = 31.700, P < 0.001), CD209b (F = 177.400, P < 0.001), GATA4 (F = 17.740, P < 0.001), and Maf mRNA expression (F = 72.710, P < 0.001), and reduced mRNA expression of Stabilin-1, Stabilin-2, Ehd3, CD209b, GATA4 and Maf genes was quantified in three infection groups than in the control group (all P values < 0.001). Conclusions E. multilocularis infections may induce capillarization of LSECs in mice, and result in a reduction in the expression of functional and phenotypic marker genes of LSECs, and capillarization of LSECs occurs earlier than activation of HSC and development of hepatic fibrosis.

RESUMO

Objective: To understand the incidence of chronic obstructive pulmonary disease (COPD) in the Suzhou cohort, and explore the risk factors for the development of COPD in Suzhou, and provide a scientific basis for COPD prevention. Methods: This study was based on the China Kadoorie Biobank project in Wuzhong District, Suzhou. After excluding individuals with airflow obstruction and self-reported chronic bronchitis, emphysema, or pulmonary heart disease at baseline, 45 484 individuals were finally included in the analysis. Cox proportional risk models were used to analyze risk factors of COPD and calculate hazard ratios and 95% confidence interval (CI) in the Suzhou cohort. The effect modifications of smoking on the association between other risk factors and COPD were evaluated. Results: Complete follow-up was available through December 31, 2017. Participants were followed up for a median of 11.12 years, and 524 individuals were diagnosed with COPD during the follow-up period; the incidence was 105.54 per 100 000 person-years. Multivariate Cox proportional risk regression models showed that age (HR=3.78, 95%CI:3.32-4.30), former smoking (HR=2.00, 95%CI:1.24-3.22), current smoking (<10 cigarettes/day, HR=2.14, 95%CI:1.36-3.35;≥10 cigarettes/day, HR=2.69, 95%CI:1.60-4.54), history of respiratory disease (HR=2.08, 95%CI:1.33-3.26), daily sleep duration ≥10 hours (HR=1.41, 95%CI:1.02-1.95) were associated with increased risk of COPD. However, education level of primary school and above (primary or junior high school, HR=0.65, 95%CI:0.52-0.81; high school and above, HR=0.54, 95%CI:0.33-0.87), consuming fresh fruit daily (HR=0.59, 95%CI:0.42-0.83) and consuming spicy food weekly (HR=0.71, 95%CI:0.53-0.94) were associated with reduced risk of COPD. Conclusions: The incidence of COPD is low in Suzhou. Older age, smoking, history of respiratory disease, and long sleep duration were risk factors for the development of COPD in the Suzhou cohort.

RESUMO

Objective: To investigate the distribution of blood pressure and analyze the associated factors of blood pressure of the elderly with type 2 diabetes in Jiangsu Province. Methods: The elderly over 60 years old participants with type 2 diabetes in the communities of Huai'an City and Changshu City, Jiangsu Province were selected in this study. They were divided into two groups: taking antihypertensive drugs and not taking antihypertensive drugs. The demographic characteristics, such as age and sex, and relevant factors were collected by questionnaire. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by physical examination. The percentile of SBP and DBP in each age group of men and women were described. The kernel density estimation curve was used to show the blood pressure distribution. The trend of blood pressure with age was fitted by locally weighted regression. The logistic regression model was used to analyze relevant factors of blood pressure. Results: A total of 12 949 participants were included in this study, including 7 775 patients in the antihypertensive drug group and 5 174 patients in the group without antihypertensive drugs. The SBP of participants was concentrated at 140-160 mmHg, and their DBP was concentrated at 75-85 mmHg. There were significant differences in the distribution of blood pressure among the subgroups of body mass index (BMI) and rural areas whether taking antihypertensive drugs and not. For participants aged under 80 years old, the SBP showed an increasing trend with age and the DBP showed a decreasing trend with age. Age, BMI ≥24 kg/m2, fasting blood glucose ≥7.0 mmol/L, living in rural areas and no smoking were influencing factors of the elevated SBP; BMI ≥24 kg/m2, male, living in rural areas, no smoking, drinking alcohol and not receiving drug hypoglycemic treatment were influencing factors of the elevated DBP. Conclusion: The SBP of older diabetic adults in Jiangsu Province is at a high level, and the distribution of blood pressure is significantly different between men and women in taking antihypertensive drugs group. The SBP presents a rising trend and the DBP is decreasing at the age of 60-80 years. The blood pressure level of this population are mainly affected by age, BMI, urban and rural areas, smoking.

RESUMO

Clouston syndrome (OMIM #129500), also known as hidrotic ectodermal dysplasia type 2, is a rare autosomal dominant skin disorder. To date, four mutations in the GJB6 gene, G11R, V37E, A88V, and D50N, have been confirmed to cause this condition. In previous studies, the focus has been mainly on gene sequencing, and there has been a lack of research on clinical manifestations and pathogenesis. To confirm the diagnosis of this pedigree at the molecular level and summarize and analyse the clinical phenotype of patients and to provide a basis for further study of the pathogenesis of the disease, we performed whole-exome and Sanger sequencing on a large Chinese Clouston syndrome pedigree. Detailed clinical examination included histopathology, hair microscopy, and scanning electron microscopy. We found a novel heterozygous missense variant (c.134G>C:p.G45A) for Clouston syndrome. We identified a new clinical phenotype involving all nail needling pain in all patients and found a special honeycomb hole structure in the patients' hair under scanning electron microscopy. Our data reveal that a novel variant (c.134G>C:p.G45A) plays a likely pathogenic role in this pedigree and highlight that genetic testing is necessary for the diagnosis of Clouston syndrome.

RESUMO

Objective:To investigate the clinical, pathological and genetic characteristics of myopathy-type very long chain acyl-coenzyme A dehydrogenase deficiency (VLCADD).Methods:The detailed clinical data, muscle biopsy pathology and molecular results of 4 patients with genetically confirmed myopathy-type VLCADD admitted to Henan Provincial People′s Hospital and Xuanwu Hospital, Capital Medical University from June 2014 to November 2019 were retrospectively analyzed.Results:All of the 4 patients were late-onset myopathy-type VLCADD. The onset age ranged from 13 to 16 years, with a mean age of 14.5 years. The age at diagnosis ranged from 21 to 54 years, with a mean age of 42.5 years. The main clinical manifestation was repeated rhabdomyolysis, including myalgia, weakness and dark urine. Obvious somnolence was observerd in 1 patient. Muscle biopsy pathology revealed mild lipid accumulation, without vacuoles. Six ACADVL variations were detected in the 4 patients, including c.1283G>A (p.R428H), c.1532G>A (p.R511Q), c.833_835delAGA (p.K278del), c.1843C>T (p.R615 *), c.1748C>T (p.S583L) and c.1391C>T (p.T464I),among which c.1391C>T (p.T464I) was a novel variation, predicted to be likely pathogenic. Other 5 variations were reported pathogenic variations. Conclusions:Myopathy-type VLCADD is characterized by paroxysmal rhabdomyolysis and can be associated with somnolence. There is no specificity in muscle pathology. There are ACADVL variations, among which c.1391C>T is a novel variation.

RESUMO

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.Methods:Sixty-eight pediatric patients of both sexes, aged 3-15 yr, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, undergoing elective lower extremity orthopedic surgery under general anesthesia, were divided into 2 groups ( n=34 each) by the random number table method: TEAS group (group T) and control group (group C). In group T, the bilateral Hegu and Neiguan acupoints were stimulated starting from 10 min before induction of anesthesia until the end of procedure, with the frequency of disperse-dense wave of 2/10 Hz, and the current intensity was gradually adjusted to the maximum intensity (10-15 mA) that children could tolerate. In group C, the electrodes were applied to the same acupoints, but electrical stimulation was not applied. The severity of pain was assessed by the Faces Pain Scale-Revised scale immediately after returning to the ward and at 2, 24 and 48 h after operation. The emergence agitation was evaluated using the Pediatric Anesthesia Emergence Delirium scale. The intraoperative consumption of propofol and remifentanil and time to extubation after stopping administration were recorded. The time to first pressing of patient-controlled analgesia (PCA), effective pressing times of PCA on 1st and 2nd days after surgery and postoperative adverse reactions such as postoperative nausea and vomiting, pruritus, drowsiness, and respiratory depression were recorded. Results:Compared with group C, the Faces Pain Scale-Revised scale scores were significantly decreased immediately after returning to the ward and at 2, 24 and 48 h after operation, the incidence of emergence agitation and intraoperative consumption of remifentanil were decreased, the time to extubation was shortened, the time to first pressing of PCA was prolonged, and the effective pressing times of PCA on 1st and 2nd days after surgery were decreased ( P<0.05). There was no significant difference in the intraoperative consumption of propofol and incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:TEAS can effectively enhance the effect of postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.

RESUMO

Objective To evaluate the short-term effect of self-management group project for chronic disease patients in Suzhou. Methods Eight to ten streets / towns were randomly selected from 10 cities and districts under the jurisdiction of Suzhou. Each street / town set up a chronic disease self-management group and carried out group activities. The awareness rate of chronic disease related knowledge, health management behavior and health status of the group members after and before the activities were compared to evaluate the short-term effect of the self-management group project. Results A total of 89 chronic disease self-management groups were set up in Suzhou in 2020. Among them, there were 47 hypertension groups and 42 diabetes groups. A total of 1176 people were surveyed at baseline, and 1161 people participated in the evaluation survey after the group activities. By setting up self-management groups, the awareness rates of chronic disease-related knowledge (BMI range, variety of food intake per day per week, moderate-intensity activity time per week, daily salt intake, harm of excessive salt intake, diagnostic criteria for hypertension, sodium content in low sodium salt, fasting blood glucose criteria, low-density lipoprotein control targets) in hypertension and diabetes patients after the intervention were improved compared with those before the intervention, and the differences were statistically significant (P“self-monitoring blood pressure” increased from 52.80% before the intervention to 66.32%, while the proportion of "having a blood glucose monitoring system at home" increased from 52.80% before the intervention to 66.32%, and the proportion of “self-monitoring blood glucose” increased from 25.67% before the intervention to 38.67%. The percentage of "drinking alcohol in the past 30 days" dropped from 12.14% before the intervention to 8.35%. All these differences were statistically significant. There was no difference in the number of "smoking in the past 30 days" compared with before the activity (P≥0.05). The number of days with poor health resulting from injuries in the past 30 days also decreased but the difference was not statistically significant (P≥0.05). In terms of the severity of depression, the number of people with moderate and severe depression decreased after the intervention, and the number of people who turned into mild depression increased, and the difference was statistically significant (P<0.05). Conclusion The self-management group project for chronic disease patients in Suzhou has achieved good results and is suitable for continued promotion and application in this region.

RESUMO

Objective To explore the epidemiological characteristics and trend of lung cancer mortality in Suzhou, to predict the future lung cancer mortality by ARIMA model, and to provide a scientific basis for the research of lung cancer prevention and control strategy. Methods The annual change percentage (APC) was used to analyze the annual change trend of lung cancer mortality from 2001 to 2020, and the ARIMA optimal model was employed to predict the lung cancer mortality from 2021 to 2025. Results The average annual crude mortality of lung cancer in Suzhou from 2001 to 2020 was 46.45/100 000, while the standardized mortality was 23.51/100 000. In recent 20 years, the crude mortality showed an upward trend and the standardized mortality showed a downward trend (APC crude rate = 2.51%, APC standardized rate = -0.78% , P < 0.001). The standardized mortality of lung cancer in men was 3.22 times that in women. The mortality of lung cancer in people over 45 years old increased with the increase of age, but the mortality in the 30-59 years old group showed a downward trend year by year. ARIMA model predicted that the annual trend of lung cancer crude mortality will tend to be flat in the next five years. Conclusion The crude mortality rate of lung cancer in Suzhou shows an upward trend, while the standardized mortality rate decreases year by year, suggesting that we should pay attention to the prevention and control of lung cancer in the elderly, accurately identify high-risk population of lung cancer, promote health publicity and education, carry out lifestyle intervention, and popularize the early screening of lung cancer.

RESUMO

Objective: To investigate the association between long-term fasting blood glucose (FPG) variability and all-cause mortality in patients with type 2 diabetes. Methods: A total of 7 174 type 2 diabetic patients included in National Basic Public Health Service Program in Changshu of Jiangsu Province were recruited as participants. Long-term glucose variability was assessed using standard deviation (SD), coefficient of variation (CV), average real variability (ARV), and variability independent of the mean (VIM) across FPG measurements at the more than three visits. Death information were mainly obtained from the death registry system in Jiangsu. Then Cox proportional hazards regression models were used to estimate the associations of four variability indicators and all-cause mortality's hazard ratios (HRs) and their 95%CIs. Results: Among 55 058.50 person-years of the follow-up, the mean follow-up time was 7.67 years, and 898 deaths occurred during the follow-up period. After adjustment, compared with T1 group, the Cox regression model showed that HRs of T3 group in SD, CV, ARV and VIM were 1.24 (95%CI: 1.03-1.49), 1.20 (95%CI: 1.01-1.43), 1.28 (95%CI: 1.07-1.55) and 1.20 (95%CI:1.01-1.41), respectively. HRs of per 1 SD higher SD, CV, ARV and VIM were 1.13 (95%CI: 1.06-1.21), 1.08 (95%CI: 1.01-1.15), 1.05 (95%CI: 1.00-1.12) and 1.09 (95%CI: 1.02-1.16) for all-cause mortality, respectively. In the stratified analysis, age, gender, hypoglycemic agent and insulin uses had no effect on the above associations (all P for interaction >0.05). Conclusion: Long-term FPG glycemic variability was positively associated with the risk of all-cause mortality in type 2 diabetes patients.

RESUMO

Cocrystal separation technology is a technology that utilizes coformers to selectively form cocrystals with target compounds and separate them from mixed systems. Our study used puerarin (PUE), daidzein (DDZ), and genistein (GEN) as model drugs, which have similar structures and are the main isoflavones in Pueraria lobata root. The separation and purification processes in the modern traditional Chinese medicine (TCM) of these three components use conventional column chromatography, recrystallization, and other technologies, which have the issues of lengthy separation cycles, high solvent consumption, and inefficient preparation. Different with existing separation technology, our team used the early-found cocrystal separation method to design a step-by-step extraction and separation experiment of GEN-PUE-DDZ ternary mixture. Caffeine and L-proline were added to the mixed system in turn, GEN-caffeine cocrystal and PUE-proline cocrystal were prepared by suspension method. The cocrystals precipitated out of the solution. The purities of the GEN-caffeine cocrystal and the PUE-proline cocrystal could achieve 93% (the purity of GEN) and 99% (the purity of PUE). Besides, the purity of DDZ could also be increased by 6.76 times. This study proposed a simple operating, low cost and wide application range separation method different from the traditional separation method and realized the separation of structurally similar chemical components in TCM, laying a foundation for the application of cocrystal technology in the separation and refining of TCM.

RESUMO

OBJECTIVES@#To investigate the changes and significance of type 2 innate lymphoid cells (ILC2), interleukin-33 (IL-33), interleukin-25 (IL-25), thymic stromal lymphopoietin (TSLP), interleukin-5 (IL-5), and interleukin-13 (IL-13) in peripheral blood of preterm infants with bronchopulmonary dysplasia (BPD).@*METHODS@#A total of 76 preterm infants with a gestational age of <32 weeks and a length of hospital stay of ≥14 days who were admitted to the Department of Pediatrics of the Affiliated Hospital of Jiangsu University from September 2020 to December 2021 were enrolled. According to the diagnostic criteria for BPD, they were divided into a BPD group with 30 infants and a non-BPD group with 46 infants. The two groups were compared in terms of the percentage of ILC2 and the levels of IL-33, IL-25, TSLP, IL-5, and IL-13 in peripheral blood on days 1, 7, and 14 after birth.@*RESULTS@#The BPD group had significantly lower birth weight and gestational age than the non-BPD group (P<0.05). On days 7 and 14 after birth, the BPD group had significantly higher levels of ILC2, IL-33, TSLP, and IL-5 than the non-BPD group (P<0.05), and these indices had an area under the curve of >0.7 in predicting the devolpment of BPD (P<0.05). Multivariate logistic regression analysis showed that after adjusting for gestational age and birth weight, peripheral blood IL-33, TSLP and IL-5 on days 7 and 14 after birth were closely related to the devolpment of BPD (P<0.05).@*CONCLUSIONS@#Early innate immune activation and upregulated expression of related factors may be observed in preterm infants with BPD. ILC2, IL-33, TSLP, and IL-5 may be used as biological indicators for early diagnosis of BPD.

RESUMO

This study was designed to investigate the cardiovascular effects of sulfur dioxide (SO2) in the caudal ventrolateral medulla (CVLM) of anesthetized rats and its mechanism. Different doses of SO2 (2, 20, 200 pmol) or artificial cerebrospinal fluid (aCSF) were injected into the CVLM unilaterally or bilaterally, and the effects of SO2 on blood pressure and heart rate of rats were observed. In order to explore the possible mechanisms of SO2 in the CVLM, different signal pathway blockers were injected into the CVLM before the treatment with SO2 (20 pmol). The results showed that unilateral or bilateral microinjection of SO2 reduced blood pressure and heart rate in a dose-dependent manner (P < 0.01). Moreover, compared with unilateral injection of SO2 (2 pmol), bilateral injection of 2 pmol SO2 produced a greater reduction in blood pressure. Local pre-injection of the glutamate receptor blocker kynurenic acid (Kyn, 5 nmol) or soluble guanylate cyclase (sGC) inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 1 pmol) into the CVLM attenuated the inhibitory effects of SO2 on both blood pressure and heart rate. However, local pre-injection of nitric oxide synthase (NOS) inhibitor NG-Nitro-L-arginine methyl ester (L-NAME, 10 nmol) only attenuated the inhibitory effect of SO2 on heart rate but not blood pressure. In conclusion, SO2 in rat CVLM has cardiovascular inhibitory effects, and its mechanism is related to the glutamate receptor and NOS/cGMP signal pathways.

RESUMO

Objective: To explore the epidemiological characteristic of a COVID-19 outbreak caused by 2019-nCoV Omicron variant BF.7 and other provinces imported in Shenzhen and analyze transmission chains and characteristics. Methods: Field epidemiological survey was conducted to identify the transmission chain, analyze the generation relationship among the cases. The 2019-nCoV nucleic acid positive samples were used for gene sequencing. Results: From 8 to 23 October, 2022, a total of 196 cases of COVID-19 were reported in Shenzhen, all the cases had epidemiological links. In the cases, 100 were men and 96 were women, with a median of age, M (Q1, Q3) was 33(25, 46) years. The outbreak was caused by traverlers initial cases infected with 2019-nCoV who returned to Shenzhen after traveling outside of Guangdong Province.There were four transmission chains, including the transmission in place of residence and neighbourhood, affecting 8 persons, transmission in social activity in the evening on 7 October, affecting 65 persons, transmission in work place on 8 October, affecting 48 persons, and transmission in a building near the work place, affecting 74 persons. The median of the incubation period of the infection, M (Q1, Q3) was 1.44 (1.11, 2.17) days. The incubation period of indoor exposure less than that of the outdoor exposure, M (Q1, Q3) was 1.38 (1.06, 1.84) and 1.95 (1.22, 2.99) days, respcetively (Wald χ2=10.27, P=0.001). With the increase of case generation, the number and probability of gene mutation increased. In the same transmission chain, the proportion of having 1-3 mutation sites was high in the cases in the first generation. Conclusions: The transmission chains were clear in this epidemic. The incubation period of Omicron variant BF.7 infection was shorter, the transmission speed was faster, and the gene mutation rate was higher. It is necessary to conduct prompt response and strict disease control when epidemic occurs.

RESUMO

Fel Ursi is a dried product obtained from the gallbladder of Ursidae animals, such as Selenarctos thibetanus or Ursus arctos, through gallbladder surgery for bile drainage. It is one of the rare animal medicinal materials in China and is known for its therapeutic effects, including clearing heat, removing toxins, extinguishing wind, relieving spasms, clearing the liver, and improving vision. Research has also found that Fel Ursi has pharmacological effects against cardiovascular and cerebrovascular diseases, such as anti-inflammatory, anti-apoptotic, and antioxidant stress properties. Recently, numerous studies have confirmed the close relationship between cardiovascular and cerebrovascular diseases and the gut microbiota as well as gut metabolites. Fel Ursi contains bile acid components that may have bidirectional regulatory effects on the gut microbiota and gut metabolites. This aspect could represent a potential therapeutic pathway for Fel Ursi in the treatment of cardiovascular and cerebrovascular diseases. This article comprehensively summarized relevant literature in China and abroad, reviewed the research progress on the pharmacological effects of Fel Ursi against cardiovascular and cerebrovascular diseases, and explored the impact of Fel Ursi on gut microbiota and gut metabolites, thereby aiming to provide references for further in-depth research and clinical application of Fel Ursi.

RESUMO

Lixuwang~® Xuesaitong Soft Capsules(referred to as "Xuesaitong Soft Capsules") have the effects of promoting blood circulation, resolving blood stasis, and dredging meridians and collaterals. They are widely used in the prevention and treatment of cardiovascular and cerebrovascular diseases in clinical practice. Through years of clinical observation, they have shown significant efficacy in ischemic stroke, coronary heart disease, and other diseases, and have been recommended by multiple guidelines, consensus statements, and monographs. Based on the summary of clinical application experience by doctors and existing evidence-based research, following the Technical Specifications for Consensus Development of Chinese Patent Medicine by Clinical Experts issued by Standardization Office of the Chinese Association of Traditional Chinese Medicine, a nominal group method was used to reach 19 recommended opinions/consensus suggestions. This document proposes the timing of medication, syndrome differentiation for medication, therapeutic effects, dosage and administration, treatment duration, economic considerations, and safety considerations in the use of Xuesaitong Soft Capsules for the treatment of ischemic stroke and angina pectoris in coronary heart disease. It is intended for doctors in internal medicine, encephalopathy(neurology), cardiovascular medicine, geriatrics, emergency medicine, general practice, and traditional Chinese medicine departments of various medical institutions, as well as pharmacists in hospitals and pharmacies, as a medication reference when using Xuesaitong Soft Capsules. It is hoped that the widespread application of this consensus can improve the clinical efficacy of Xuesaitong Soft Capsules in the treatment of ischemic stroke and coronary heart disease, promote rational drug use, and reduce medication risks. This consensus has been reviewed and published by the China Association of Traditional Chinese Medicine, with the identification number GS/CACM 323-2023.

RESUMO

Objective To compare the functional status of diabetic patients with and without nephropathy and identify the items that diabetic patients with nephropathy are more likely to develop dysfunction than diabetic patients without nephropathy based on the international classification of functioning,disability and health rehabilitation set(ICF-RS).Methods A cross-sectional study was conducted.A total of 320 diabetic patients hospitalized in Guangdong Provincial Hospital of Chinese Medicine from August 2021 to February 2022 were selected and assigned into a group with nephropathy and a group without nephropathy.The general characteristics,clinical examination,and laboratory findings were compared by the t test,rank sum test,and Chi-squared test.The functional status of the patients was compared between the two groups by the t test based on the ICF-RS.Logistic regression was employed to control interferential factors between the two groups and identify the association between nephropathy and ICF-RS problematic items among diabetic patients.Results The diabetic patients with nephropathy had more problematic items in ICF-RS(P<0.001),the body function dimension(P=0.003),the activity dimension(P<0.001),and the participation dimension(P<0.001)than those without nephropathy.Moreover,the diabetic patients with nephropathy experienced severer problems in 5 body function items(energy and drive functions,sleep functions,sexual functions,exercise tolerance functions,and muscle power functions),10 activity items(transferring oneself,walking,moving around using equipment,moving around,washing oneself,caring for body parts,toileting,dressing,doing housework,and looking after one's health),and 4 participation items(using transportation,assisting others,basic interpersonal interactions,and recreation and leisure)(all P<0.05).The Logistic regression results showed that compared with the diabetic patients without nephropathy,the diabetic patients with nephropathy were more likely to develop problems in energy and drive functions(aOR=4.35,95%CI=1.28-14.79,P=0.019),emotional functions(aOR=1.88,95%CI=1.06-3.34,P=0.031),sexual functions(aOR=3.39,95%CI=1.82-6.34,P<0.001),moving around(aOR=3.11,95%CI=1.76-5.52,P<0.001),doing housework(aOR=17.48,95%CI=3.57-85.60,P<0.001),looking after one's health(aOR=1.97,95%CI=1.13-3.43,P=0.017),using transportation(aOR=2.59,95%CI=1.38-4.88,P=0.003),and recreation and leisure(aOR=2.52,95%CI=1.46-4.35,P<0.001).Conclusion Compared with the diabetic patients without nephropathy,the patients with nephropathy suffer more ICF-RS problematic items and are more likely to develop dysfunction in certain items in all the three dimensions.

RESUMO

Background@#The common reference intervals (RIs) for thyroid hormones currently used in China are provided by equipment manufacturers. This study aimed to establish thyroid hormone RIs in the population of Lanzhou, a city in the subplateau region of northwest China, and compare them with previous reports and manufacturer-provided values. @*Methods@#In total, 3,123 individuals (1,680 men, 1,443 women) from Lanzhou, an iodine-adequate area of China, perceived as healthy were selected. The Abbott Architect analyzer was used to determine the serum concentration of thyroid hormones. The 95% RI was estimated using the 2.5th and 97.5th percentiles as the lower and upper reference limits, respectively. @*Results@#The serum levels of thyroid-stimulating hormone (TSH), total triiodothyronine (TT3), antithyroglobulin (ATG) antibody, and antithyroid peroxidase (ATPO) antibody levels were significantly correlated with sex (P0.05). The established RIs of TSH, ATG, and ATPO in this study differed between sexes (P<0.05). The thyroid hormone RIs established herein were inconsistent with the manufacturer-provided values. @*Conclusion@#The RIs of thyroid hormones in the healthy population of Lanzhou were inconsistent with those in the manufacturer’s manual. Validated sex-specific values are required for diagnosing thyroid diseases.
