RESUMO
The aim of the work was to investigate the correlation between serum TSH (thyrotropin) levels within normal range and serum lipids. A total of 1962 subjects with normal thyroid function were enrolled. The subjects were divided into four groups according to the quartiles of serum normal TSH levels, [Q1 (0.27-1.68) mIU/l, Q2 (1.69-2.35) mIU/l, Q3 (2.36-3.07) mIU/l, and Q4 (3.08-4.20) mIU/l]. The effect of serum normal TSH levels on serum lipid profiles of different age or gender was analyzed. The total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) levels of the Q3 group and TG levels of the Q4 group were higher than those of the Q1 group in youth (p <0.05). The TC levels of the Q3 group were higher than those of the Q2 group in middle age (p <0.05). The LDL-C levels of middle age or elderly were higher than those of youth at the same TSH levels (p <0.05), while the TC levels of middle age were higher than those of youth in Q1, Q3, or Q4 group (p <0.05), and the TC and HDL-C levels of elderly were higher than those of youth in the Q2 group (p <0.05). The TG levels of the Q3 group were higher than those of Q1 group in males (p <0.05). The LDL-C levels of the Q3 group were higher than those of the Q1 group in females (p <0.05). In conclusion, the normal serum TSH levels were found to be closely related to serum lipid profiles, and with increasing TSH levels, serum lipids levels increased gradually.

BACKGROUND: Domestic violence is common in the community. Many of its victims present to primary care physicians (PCPs) but are not being recognized and managed. The barriers, with specific reference to a Chinese cultural context, were investigated earlier. This paper explored the factors which facilitated the process of recognizing and managing suspected cases of domestic violence by PCPs in Hong Kong. METHODS: Four focus group interviews were conducted to explore in-depth the experiences of PCPs in recognition, management and referral of domestic violence cases from which facilitators were identified. The relevant themes were then investigated in a questionnaire survey with 504 PCPs working in public and private sectors. RESULTS: The focus group participants emphasized mood symptoms as useful indicators for probable abuse and continuity of care was important to unmask issues of domestic violence. The top facilitators perceived by the respondents of the survey included: a trusting doctor-patient relationship (99.8%), good communication skills (99.0%), patients' unexplained bruises (96.3%), medical history (94.6%), and mood symptoms (94.4%). Further, the survey found that PCPs with longer years of practice, a medical degree obtained from Western countries, and postgraduate training in family counselling or psychological medicine perceived more facilitators in managing domestic violence. CONCLUSIONS: Without a local screening policy and training protocol to manage domestic violence, PCPs regarded their skills in mental healthcare and good relationships with patients as the key facilitators. While training in mental health care helps PCPs manage domestic violence, a specific protocol emphasizing medical-social collaboration is anticipated to facilitate them to take a more proactive and effective stance from screening to management.

OBJECTIVES: The WHO recommends dual testing for HIV and syphilis among key populations, including men who have sex with men (MSM). We assessed the proportion of men who had dual tested and reasons for not dual testing. METHODS: In 2017, an online survey of MSM was conducted in eight cities from two provinces in China. Data on sociodemographics and sexual behaviours were collected. Descriptive analysis was used to examine the experience of dual testing. Multivariable logistic regression identified characteristics associated with men who had dual tested. RESULTS: Among 802 men who had ever tested for HIV, 297 dual tested (37%, 95% CI 34 to 40). Men dual tested in a variety of settings: public hospital (35%), voluntary counselling and testing sites (28%), self-testing at home (18%), community-based organisation (8%), community health centre (7%), other (3%) or private hospital (1%). Greater odds for dual testing was found in men who had disclosed their sexuality to a healthcare provider (adjusted OR (AOR) 1.81, 95% CI 1.27 to 2.59, p=0.001), and who had substantial (AOR 2.71, 95% CI 1.67 to 4.41, p<0.001) or moderate community engagement in sexual health (AOR 2.30, 95% CI 1.49 to 3.57, p<0.001), compared with those with no community engagement. The most common reasons for not dual testing were no knowledge that they could be dual tested (34%), did not ask the doctor to be dual tested (25%) and did not believe they were at risk for syphilis (19%). CONCLUSIONS: Chinese MSM are dual testing through a variety of test sites, including home self-testing. However, the overall dual testing rate remains low despite recent efforts to integrate HIV and syphilis testing.

OBJECTIVE: To identify the risk factors for residual lesion in hysterectomy specimens after loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN). METHODS AND RESULTS: We retrospectively analyzed the clinical data of 594 patients who underwent total hysterectomy after LEEP for CIN at the International Peace Maternity and Child Health Hospital affiliated to Shanghai Jiaotong University between July 2006 and June 2015. Among the 594 patients, there were no residual lesions in uterine specimens of 409 (68.9%) patients; residual CIN1 was found in 24 (4%) patients, CIN2 and CIN3 in 142 (23.9%) patients, and cervical cancer in 19 (3.2%) patients. On univariate analysis age, menopausal status, margin involvement, lesion grade, abnormal endocervical curettage (ECC) result, and persistent human papillomavirus (HPV) infection post operation were significantly associated with residual lesions after LEEP (P < 0.05). Multivariate regression analysis using the logistic regression model showed abnormal ECC result and persistent HPV positivity to be independent risk factors for residual lesions after LEEP. LEEP with positive margins and persistent HPV infection were also associated with high risk of invasive cervical cancer in CIN2+ patients. CONCLUSIONS: Abnormal ECC result and post-treatment HPV infection are predictors of residual lesion after LEEP. In combination, they could be useful for risk stratification and selection of the management approach. Postmenopausal CIN2+ patients with positive margins and persistent postoperative HPV infection may have high risk of cervical invasive cancer.

Objective: This study aimed to investigate the health performance of the Urban and Rural Residents Medical Insurance (URRMI) scheme in China and to make practical recommendations and scientific references for its full implementation in China. Methods: This is a panel study that uses data from the China Family Panel Studies from 2018 to 2020, which is separated into treated and control groups each year, utilizing the key approach of propensity score matching and difference-in-difference (PSM-DID). Using 1-to-1 k-nearest neighbor matching, we proportionate the baseline data. Using difference-in-difference model, we examine the mean treatment impact of the outcome variables. Using a 500-time random sample regression model, we validate the robustness of the model estimation. Results: The result was credible after matching, minimizing discrepancies. Good overall performance of self-rated health with an average Hukou status of, respectively, 0.8 and 0.4 in the treated and control group, primarily in rural and urban regions separately. The participation of URRMI significantly impacted self-rated health of residents, with a 0.456-unit improvement probabilities observed (p < 0.1). Additionally, the individuals are categorized into urban and rural, and those with urban hukou had a 0.311 expansion in the probability of having better health status compared to rural hukou (p < 0.05). Other factors, such as age, highest education, annual income, medical expenditure, hospital scale, clinic satisfaction, and napping, also impacted self-rated health. Moreover, elder individuals, higher education levels, and higher medical expenditure having a higher probability of improvement. The study utilized a placebo test to verify the robustness of the URRMI regression. The estimated coefficients showed that basic medical insurance did not significantly improve the health of insured residents under the URRMI scheme. Conclusion: The study demonstrates the crucial role of PSM-DID in determining the influence of URRMI on self-rated health status. It indicates that purchasing in URRMI has a favorable influence on the health of residents, advancing enhanced self-rated health effectiveness. It does, however, reveal geographical disparities in health, with urban dwellers faring far better than those who live in the suburb. Study suggests expanding URRMI coverage, narrowing urban-rural divide, increasing insurance subsidies, reforming laws, and developing effective advertising strategies.

Background: Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection. Although fish oil has been used as an immunonutritional preparations for the treatment of sepsis patients, there is still controversy as to whether it is beneficial to them. We systematically reviewed published clinical trial data to evaluate the effectiveness of fish oil-containing nutrition supplementation in sepsis patients. Methods: A systematic search was undertaken in PubMed, Embase, Chinese Biomedicine Database, the Cochrane Library and the China Knowledge Resource Integrated Database to obtain clinical controlled trails. RCTs on nutrition therapy containing fish oil among adult sepsis patients were selected for analysis in comparison with routine therapy. Results: Twenty-five published trials were included in the meta-analysis. Fish oil-containing nutrition supplementation reduced the mortality compared with the control group (relative risk (RR) 0.74, I 2 = 0%). Fish oil also shortened the ICU stay (MD -3.57 days; 95% CI -4.54, -2.59; p<0.00001; I 2 = 76%), hospital stay (MD -9.92 days; 95% CI -15.37, -4.46; p = 0.0004; I 2 = 91%) and the duration of mechanical ventilation support (MD -2.26; 95% CI -4.27, -0.26; p = 0.03; I 2 = 83%). A subgroup analysis based on the route of administration revealed that parenteral administration of fish oil could reduce mortality in septic patients (RR =0.68, I 2 = 0%), but no significant difference in mortality was observed in the fish oil group administered by enteral route (RR = 0.80, I 2 = 0%). No statistically significant publication biases were detected for the above clinical endpoints (p>0.05). Conclusions: Parenteral nutrition containing fish oil could significantly decrease mortality in sepsis patients while enteral administration could not. Fish oil-containing nutrition supplementation.
RESUMO
BACKGROUND: To understand the long-term oncologic outcomes of open radical cystectomy (ORC) versus laparoscopic radical cystectomy (LRC) versus robot-assisted radical cystectomy (RARC) for bladder cancer (BCa). Therefore, we performed the conventional meta-analysis and network meta-analysis to evaluate the long-term oncologic outcomes of ORC, LRC, and RARC for BCa. METHODS: A systematic search of PubMed, Embase, Cochrane Library, Medline, and Web of science was performed up until July 1, 2021. Long-term oncologic outcomes include the 5-year overall survival (OS) rate, the 5-year recurrence-free survival (RFS) rate, and the 5-year cancer specific-survival (CSS) rate. The Bayesian network analysis has been registered in PROSPERO (CRD42020208396). RESULTS: We found that 10 articles (including 3228 patients) were included in our Bayesian network analysis. No significant differences were found between ORC, LRC, and RARC in long-term oncologic outcomes in either direct meta-analysis or network meta-analysis. Therefore, the clinical effects of 5-year OS, RFS, and CSS of RARC, LRC, and ORC are similar. But LRC may be ranked first in 5-year OS, RFS, and CSS compared to other surgical approaches by probabilistic analysis ranking via Bayesian network analysis. CONCLUSION: We found that there were no statistical differences in the 3 surgical approaches of RAPC, LPC, and OPC for Bca in long-term oncologic outcomes by direct meta-analysis. However, Subtle differences between these surgical approaches can be concluded that LRC may be a better surgical approach than RARC or ORC in long-term oncologic outcomes by probabilistic analysis ranking via Bayesian network analysis. Moreover, we need a large sample size and more high-quality studies to improve and verify further.

RESUMO
Objective To investigate the risk factors for postoperative pulmonary infection in pa-tients undergoing liver transplantation.Methods Clinical data of 1 358 patients who underwent liver trans-plantation for the first time from June 2005 to June 2013 at three clinical medical centers were retrospectively analyzed.Patients were divided into two groups according to whether or not they developed lung infection within 30 days after surgery:the infection group and the non-infection group.General,intrao-perative and postoperative data were collected,and risk factors for pulmonary infection after liver transplan-tation were analyzed using univariate analysis and binary logistic regression.Results Lung infections after liver transplantation occurred in 316 patients(23.3%),of whom 21 patients(6.7%)died.Compared with the non-infection group,the proportion of preoperative diagnosis of chronic severe hepatitis,hepatocellular carcinoma,hepatitis C cirrhosis,congenital liver disease and liver failure,preoperative combined hepatore-nal syndrome,hepatic coma and diabetes mellitus,preoperative creatinine concentration were significantly increased in the infection group(P<0.05),preoperative total protein and albumin concentrations were significantly decreased(P<0.05),and the duration of the hepatic-free period,the duration of postoperative awakening,and the duration of postoperative extubation were significantly prolonged(P<0.05),intraoperative blood loss was significantly increased(P<0.05),intraoperative urine output was significantly decreased(P<0.05),the proportion of intraoperative phenylephrine,atropine,lidocaine,and furosemide drugs were significantly decreased(P<0.05),and postoperative mortality rate was signifi-cantly increased in the infection group(P<0.05).The results of binary logistic regression analysis showed that chronic severe hepatitis,hepatitis C cirrhosis,liver failure,preoperative diabetes mellitus,intraopera-tive blood loss>1 900 ml,and postoperative awakening time>7.3 hours were the risk factors for postoper-ative pulmonary infections in liver transplant patients,and the surgical method(classical non-transfusion in situ liver transplantation),the use of lidocaine during surgery,preoperative total protein>64.6 g/L,and intraoperative urine volume>1 800 ml were protective factors for postoperative pulmonary infections in liver transplantation patients.Conclusion Preoperative diagnosis of chronic severe hepatitis,hepatitis C cirrho-sis,liver failure,preoperative combined diabetes mellitus,intraoperative blood loss>1 900 ml,and post-operative awakening time>7.3 hours are risk factors for pulmonary infection after liver transplantation.
RESUMO
The clinical treatment of hepatocellular carcinoma has been hindered due to the drug resistance and heterogeneity of tumor cells. A new therapy strategy combined chemo drugs and molecular-targeted drugs is considered to be promising for conquering these challenges. However, the different pharmacokinetic profiles, hydrophobicity and systemic toxicity of these drugs may still cause serious challenges to the clinical applications of this combination therapy. In this study, smart sorafenib (SF) and doxorubicin (DOX)-loaded nanodroplets (SF/DOX-NDs) were fabricated to solve the above issues. The liquid-to-gas phase transition of SF/DOX-NDs could function as a cavitation nucleus to boost drug release and increase cellular uptake after exposure to therapeutic ultrasound (TUS) irradiation. Additionally, this strategy has a therapeutic effect to induce apoptosis and inhibit the proliferation, migration, and invasion of hepatoma cells. Furthermore, the intense cavitation of SF/DOX-NDs at the tumor site could disrupt microvessels, which is beneficial for tissue-penetrating drug delivery inside tumors. Consequently, tumor angiogenesis was reduced, and tumor growth was remarkably inhibited by SF/DOX-NDs. These results indicated that combination therapy using SF/DOX-NDs may offer a promising approach to achieve effective HCC therapy with low side effects.

Small for gestational age (SGA) infants are more likely to experience neurocognitive impairments compared to appropriate for gestational age (AGA) infants. This paper reviews recent research on the neurocognitive development of SGA children. SGA can lead to a "brain-sparing effect" due to growth restriction, which may affect cerebral blood flow and brain structure. However, this does not guarantee normal brain development. Restrictive blood flow can result in changes in brain structure, such as reduced total white matter and gray matter volume in various brain regions, including the cerebral cortex, hippocampus and cerebellum, ultimately leading to decreased head circumference. SGA children also exhibit lower scores in all neurocognitive domains, including intelligence, attention, memory, and executive function. This may result in poor academic performance and an increased risk of social, behavioral, and neurological problems, such as cerebral palsy, epilepsy, visual and hearing impairments, as well as comorbidities like attention deficit hyperactivity disorder(ADHD), autism spectrum disorder(ASD), anxiety, depression, and schizophrenia. Several risk factors for SGA-related neurocognitive impairments have been identified, including gestational hypertension, abnormal gestational weight, smoking, and catch-up growth. Studies have shown that the best interventions to improve cognitive dysplasia include nutrient supplementation, continued breastfeeding, high-quality education, and appropriate early intervention (responsive parenting) are effective in improving cognitive outcomes for SGA children.

RESUMO
Objective To investigate the effect and possible mechanism of Maslinic acid(MA)on apoptosis of cervical cancer HeLa cells.Methods HeLa cells were treated with different concentrations of MA,and cell survival rate was detected by MTT;Cell apoptosis was detected by Annexin V-FITC/PI flow cytometry;The changes of mitochondrial membrane potential were detected by JC-1 staining;The expression levels of OMA1,optic dystrophy protein 1(OPA1),Bax,Bcl-2,cleaved caspase-3,and cytoplasmic cytochrome C(Cyt C)were detected by Western blot.Whether MA induces HeLa cell apoptosis by regulating OMA1-mediated mitochondrial apoptosis has been verified through silencing OMA1 gene expression.Results MA inhibited the proliferation of HeLa cells in a dose-dependent manner.Different concentrations of MA could increase the apoptosis rate of HeLa cells and decrease the mitochondrial membrane potential,meanwhile,the protein expression levels of OMA1,Bax,cleaved caspase-3 and Cyt C in cytoplasm were up-regulated,and the protein expression levels of OPA1 and Bcl-2 were down-regulated.Silencing OMA1 gene expression inhibited the apoptosis of HeLa cells induced by MA.Conclusion MA can inhibit the proliferation of HeLa cells and induce cell apoptosis,and the mechanism may be related to the regulation of mitochondrial apoptosis pathway mediated by OMA1.
RESUMO
As medical advances and surgical techniques have improved the survival rates of children with congenital heart disease (CHD), more and more studies have begun to focus on the quality of survival and long-term development of children with CHD. Cognitive and psychological developmental deficits in children with CHD have been well documented. With the development of brain function assessment and neuroimaging techniques in recent years, it has become possible to elucidate the mechanisms of neurocognitive impairment in patients with CHD from a brain science perspective. Providing targeted early follow-up interventions for the population with CHD and promoting their social adaptation have a great clinical significance. This review summarized recent research findings on neurocognitive developmental outcomes in children with CHD from the perspective of behavioral medicine and brain science. This paper focuses on reviewing the mechanisms of brain microstructure damage and brain network dysfunction which may explain neurocognitive impairment in children with CHD, and further explores the early monitoring and intervention programs suitable for clinical development, aiming to suggest possible directions for improving long-term neurocognitive developmental outcomes for CHD population.
RESUMO
Objective:To analyze the clinical value of noninvasive pressure strain loop (PSL) in assessing left ventricular myocardial work in patients with essential hypertension.Methods:In this cross-sectional study, 66 patients with essential hypertension who were admitted to the Affiliated Hospital of Yangzhou University from August to December 2020 were continuously enrolled. According to left ventricular mass index (LVMI) >95 g/m 2 in women and >115 g/m 2 in men,≤95 g/m 2 in women and ≤115 g/m 2 in men, the 66 patients were divided into left ventricular hypertrophy (LVH) group (14 cases) and non-left ventricular hypertrophy (NLVH) group (52 cases). Furthermore, the NLVH group was divided into a mild group (30 cases) and a moderate/severe group (22 cases) according to the systolic blood pressure of 140~159 mmHg (1 mmHg=0.133 kPa) and ≥160 mmHg. Another 25 healthy adults who underwent physical examination during the same period were included as healthy control group. The height, weight and blood pressure were measured in all the subjects, and routine echocardiography and speckle tracking imaging analysis were performed. PSL results were obtained by combining the results of speckle tracking imaging analysis with systolic blood pressure. The differences of general clinical data, basic parameters of two-dimensional ultrasound and myocardial work parameters of PSL (global work index, global effective work, global wasted work, and global work efficiency) were compared among the groups, and the clinical value of PSL in assessing left ventricular myocardial work in patients with essential hypertension was analyzed. Results:There was no significant difference in left ventricular ejection fraction among all groups (all P>0.05). The global work index of moderate/severe NLVH group was significantly higher than that of mild NLVH group, LVH group and healthy control group [(2 630±231) vs (2 254±179), (1 847±261), (1 724±209) mmHg%]. The global effective work of moderate/severe NLVH group was significantly higher than that of LVH group and healthy control group [(2 965±261) vs (2 330±258) and (2 121±163) mmHg%] (all P<0.05). The global wasted work of LVH group was significantly higher than that of moderate/severe NLVH group, mild NLVH group and healthy control group [(248±107) vs (141±57), (116±57), (83±58) mmHg%] (all P<0.05). The global work efficiency was significantly lower than that of moderate/severe NLVH group, mild NLVH group and healthy control group (89.1%±3.9% vs 94.3%±1.9%, 95.0%±1.8%, 95.8%±2.3%) (all P<0.05). With the increase of blood pressure, the PSL decreased in the LVH group and increased in the other three groups. The bull′s eye diagram of myocardial work in the healthy control group was uniform green (normal effective work area), red began to appear in the mild NLVH group (high intensity myocardial work area), red area increased in the moderate/severe NLVH group, and blue appeared in the LVH group (ineffective work area). Conclusions:PSL has good clinical value in assessing left ventricular myocardial work in patients with primary hypertension. The parameters derived from PSL data can sensitively identify impaired systolic function in individuals with normal left ventricular ejection fraction.
RESUMO
Objective To evaluate the risk factors for development of primary hepatic carcinoma(PHC)in patients with hepatitis B virus-related liver cirrhosis.Methods The cases of hepatitis B virus-related liver cirrhosis combined with PHC and hepatitis B virus-related liver cirrhosis alone were retrospectively analyzed in the Second Affiliated Hospital of Nanchang University.A total of 151 patients with hepatitis B virus-related liver cirrhosis combined with PHC were included in observation group and 136 patients with hepatitis B virus-related liver cirrhosis alone were included in control group.We have down the analysis of risk factors by χ2 test,t test and Logistic regression model.Results The clinical data of the two groups of patients showed statistically significant differences in six indicators,including gender,hepatitis B virus e antibodies(Anti-HBe),liver function grading(Child-Pugh),alpha-fetoprotein(AFP),blood glucose,and blood type,through univariate analysis(P<0.05).The results of multivariate unconditional Logistic regression analysis showed that AFP(OR=5.046,2.716,and 9.373,P<0.01)and Anti-HBe positive(OR=2.305,1.075,and 4.945,P<0.01)were risk factors for primary liver cancer.Conclusion Male shows a more possibility of occurrence of PHC than female.The positive Anti-HBe is the independent risk factors for PHC.The probability of PHC in Child-Pugh stage A is higher than that in Child-Pugh stage B and C.
RESUMO
Objective:To summarize the clinical data of anti-factor H antibody-associated atypical hemolytic uremic syndrome (aHUS) in children, and analyze the risk factors for disease recurrence and poor prognosis.Methods:A prospective cohort study was conducted on 52 children with anti-factor H antibody-associated aHUS in Beijing Children′s Hospital, Capital Medical University from November 2011 to November 2021.Patient information about the genetic background, clinical and renal pathological characteristics, treatment, and prognosis were collected.Then, the disease recurrence and prognosis were analyzed using the survival curve and Cox regression model. Results:In 52 children, there were 33 males and 19 females.The average age of onset for aHUS was 2.4-12.8 years, and 92.3%(48/52) of the children developed symptoms at the age of 4-12 years.The copy numbers of complement factor-H-related 1 (CFHR1) and complement factor-H-related 3 (CFHR3) genes were calculated in 42 children.Among the 42 cases, 18 cases (42.9%) had CFHR1 homozygous deletion, and 83.3% (15/18) of them also had CFHR3 homozygous deletion.All the patients were given plasma therapy.Besides, 76.9% (40/52) of the children were treated with immunosuppressive therapy (steroid and/or immunosuppressant) at the first onset of the disease.About 86.5%(45/52 cases) of the patients received immunosuppressive therapy in the course of disease, and the immunosuppressive treatment lasted for 6-20 months in total.The median follow-up time was 58 (28, 91) months.Among 52 patients, only 12 patients (23.1%) suffered disease recurrence.The relapse-free survival rate in children with CFHR1 homozygous deletion was significantly lower than that in children with non-homozygous deletion ( χ2=4.700, P=0.030). The relapse-free survival rate in children with CFHR1 and CFHR3 homozygous deletions was also significantly lower than that in other children ( χ2=4.181, P=0.041). At the end of the follow-up, 73.1%(38/52) of the children had normal renal function and no persistent proteinuria or hypertension.23.1%(12/52 cases) of the children had persistent proteinuria and/or hypertension.One child had Stage 3-4 chronic kidney disease, and 1 child was dialysis dependent. Conclusions:Anti-factor H antibody-associated aHUS is prone to occur in children aged between 4-12 years old, who respond well to plasma therapy and immunosuppressive therapy.Children with anti-factor H antibody-associated aHUS and CFHR1 and CFHR3 homozygous deletions have a high recurrence rate.Treatment with immunosuppressive therapy and assessment of the copy number of CFHR1 and CFHR3 genes in the early stage of the disease are important for preventing disease recurrence and improving prognosis.
