Association of stage 1 hypertension defined by the 2017 ACC/AHA guideline with cardiovascular events and mortality in Chinese adults / 中华医学杂志(英文版)

BACKGROUND@#The 2017 American College of Cardiology/American Heart Association (ACC/AHA) blood pressure (BP) guideline lowered the threshold defining hypertension to 130/80 mmHg. However, how stage 1 hypertension defined using this guideline is associated with cardiovascular events in Chinese adults remains unclear. This study assessed the association between stage 1 hypertension defined by the 2017 ACC/AHA guideline and clinical outcomes in the Chinese population.@*METHODS@#Participants with stage 1 hypertension ( n = 69,509) or normal BP ( n = 34,142) were followed in this study from 2006/2007 to 2020. Stage 1 hypertension was defined as a systolic blood pressure of 130-139 mmHg or a diastolic blood pressure of 80-89 mmHg. None were taking antihypertensive medication or had a history of myocardial infarction (MI), stroke, or cancer at baseline. The primary outcome was a composite of MI, stroke, and all-cause mortality. The secondary outcomes were individual components of the primary outcome. Cox proportional hazards models were used for the analysis.@*RESULTS@#During a median follow-up of 11.09 years, we observed 10,479 events (MI, n = 995; stroke, n = 3408; all-cause mortality, n = 7094). After multivariable adjustment, the hazard ratios for stage 1 hypertension vs. normal BP were 1.20 (95% confidence interval [CI], 1.13-1.25) for primary outcome, 1.24 (95% CI, 1.05-1.46) for MI, 1.45 (95% CI, 1.33-1.59) for stroke, and 1.11 (95% CI, 1.04-1.17) for all-cause mortality. The hazard ratios for participants with stage 1 hypertension who were prescribed antihypertensive medications compared with those without antihypertensive treatment during the follow-up was 0.90 (95% CI, 0.85-0.96).@*CONCLUSIONS@#Using the new definition, Chinese adults with untreated stage 1 hypertension are at higher risk for MI, stroke, and all-cause mortality. This finding may help to validate the new BP classification system in China.

Clinical effect of cross positioning method for correcting low and moderate astigmatism during small incision lenticule extraction / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the clinical outcomes of using the cross-positioning method for correcting low and moderate astigmatism during small incision lenticule extraction(SMILE)surgery with Alpins vector analysis.METHODS: A total of 50 patients(81 eyes)with low and moderate astigmatism with the rule ≤1.50 D who underwent SMILE surgery at the laser myopia treatment center of Xi'an No.1 Hospital from May 2022 to November 2022 were included in the prospective randomized controlled study, and they were divided into two groups according to the random table, with 25 case(41 eyes)in cross-positioning group and 25 cases(40 eyes)in control group. In the cross-positioning group, the patients' head position was adjusted based on the cross intersection lines before the standard SMILE procedure, aligning the lateral canthi with the horizontal line and the midpoint of the eyebrows and the nose bridge with the vertical line. Postoperative visual acuity and refractive results at 3 mo were observed in both groups, and astigmatic changes were analyzed and evaluated using the Alpins vector analysis method.RESULTS: During the follow-up period, 6 cases(11 eyes)in the cross-positioning group were lost to follow-up, while in the control group, 8 cases(14 eyes)were lost to follow-up, with 19 cases(30 eyes)and 17 cases(26 eyes)finally included in the cross-positioning group and the control group, respectively. At 3 mo postoperatively, the uncorrected visual acuity(UCVA)of both groups' operated eyes was ≥1.0, and no serious complications occurred, with no significant differences in UCVA, best corrected visual acuity(BCVA), spherical power, and spherical equivalent between the cross-positioning group and the control group(all P>0.05). The cylindrical power in the cross-positioning group was 0.00(0.00, 0.00)D, which was lower than -0.13(-0.50, 0.00)D in the control group(P=0.01). The vector analysis results showed that the difference vector(DV)in the cross-positioning group was lower than that in the control group [0.00(0.00, 0.00)vs 0.13(0.00, 0.50), P=0.01], and the index of success(IOS)was better than that of the control group [0.00(0.00, 0.00)vs 0.18(0.00, 0.77), P<0.01]. At 3 mo postoperatively, 26(87%)and 15(58%)eyes in the cross-positioning group and control groups achieved an angle of error(AE)within ±5°, respectively.CONCLUSION: The cross positioning method was used to calibrate the patients' head position during SMILE surgery, which reduced the axial position error and improved the accuracy of SMILE in correcting low and moderate astigmatism.

Effect of paliperidone palmitate treatment on disease family burden and rehabilitation effect in community schizophrenic patients / 上海预防医学

ObjectiveTo explore the effect of paliperidone palmitate treatment on schizophrenic patients in the community. Methods446 schizophrenic patients who used paliperidone palmitate injection were selected in Shanghai. Before and after the treatment， the disease family burden scale， the concise evaluation scale of drug treatment compliance， the VAS100 score of treatment satisfaction， the short form of quality of life measurement scale， and the screening scale of social function defects were used to evaluate the effects of paliperidone palmitate injection. The data were statistically analyzed using SPSS 26.0 software. ResultsAfter using paliperidone palmitate injection， the total score of family burden （13.94±12.17）， the score of daily family activities （3.26±2.74）， the score of family entertainment activities （2.21±2.30）， and the score of family relationship （2.79±2.76） were significantly higher than those before the treatment （14.98±12.64， 3.51±2.88， 2.48±2.38， 3.11±2.87， respectively， all with P<0.05）. The scores of the World Health Organization on quality of life brief scale （62.89±11.94） and the medication compliance scale （28.11±5.64） were better than those before treatment （60.67±12.62 and 27.37±6.96， all with P<0.05）. Compared with the prior treatment without paliperidone palmitate injection， the number of readmissions after treatment was significantly reduced （P<0.01）. ConclusionThe treatment of paliperidone palmitate injection has significant effect， which can effectively reduce the disease family burden of Schizophrenic patients， improve their quality of life， enhance their drug compliance， reduce the readmission rate of patients， ensure long-term treatment effect and promote disease recovery.

Equity and efficiency of resource allocation for management and treatment of severe mental disorders in Shanghai in 2020 / 公共卫生与预防医学

Objective To analyze the equity and efficiency of resource allocation for management and treatment of severe mental disorders in Shanghai in 2020, and to provide a foundation for making relevant policies. Methods Data on resource allocation for the management and treatment of severe mental disorders in 17 district-level mental health institutions in 2020 were collected. The Gini coefficient was used to evaluate the equity of resource allocation by population and geographic area, and data envelopment analysis was carried out to analyze the equity of resource allocation. Results The Gini coefficients of special funds, psychiatric medical staff and actual open beds according to population were 0.24, 0.25 and 0.27, respectively. The Gini coefficients according to area were 0.54, 0.62 and 0.64, respectively. The average efficiency of resource allocation was 0.865. There were 5 institutions where DEA was effective, accounting for 29.41%. There were 12 institutions where DEA was non-effective, accounting for 70.59%. Conclusion The equity of resources allocation for the management and treatment of severe mental disorders according to population is good, but the equity of allocation based on geographic area is not high. The efficiency of resource allocation needs to be further improved. It is suggested that the resource allocation should be optimized to promote the fairness and efficiency of resource allocation for the management and treatment of severe mental disorders.

Short-course radiotherapy combined with CAPOX and PD-1 inhibitor for the total neoadjuvant therapy of locally advanced rectal cancer: the preliminary single-center findings of a prospective, multicentre, randomized phase II trial (TORCH) / 中华胃肠外科杂志

Objective: Total neoadjuvant therapy has been used to improve tumor responses and prevent distant metastases in patients with locally advanced rectal cancer (LARC). Patients with complete clinical responses (cCR) then have the option of choosing a watch and wait (W&W) strategy and organ preservation. It has recently been shown that hypofractionated radiotherapy has better synergistic effects with PD-1/PD-L1 inhibitors than does conventionally fractionated radiotherapy, increasing the sensitivity of microsatellite stable (MSS) colorectal cancer to immunotherapy. Thus, in this trial we aimed to determine whether total neoadjuvant therapy comprising short-course radiotherapy (SCRT) combined with a PD-1 inhibitor improves the degree of tumor regression in patients with LARC. Methods: TORCH is a prospective, multicenter, randomized, phase II trial (TORCH Registration No. NCT04518280). Patients with LARC (T3-4/N+M0, distance from anus ≤10 cm) are eligible and are randomly assigned to consolidation or induction arms. Those in the consolidation arm receive SCRT (25Gy/5 Fx), followed by six cycles of toripalimab plus capecitabine and oxaliplatin (ToriCAPOX). Those in the induction arm receive two cycles of ToriCAPOX, then undergo SCRT, followed by four cycles of ToriCAPOX. Patients in both groups undergo total mesorectal excision (TME) or can choose a W&W strategy if cCR has been achieved. The primary endpoint is the complete response rate (CR, pathological complete response [pCR] plus continuous cCR for more than 1 year). The secondary endpoints include rates of Grade 3-4 acute adverse effects (AEs) etc. Results: Up to 30 September 2022, 62 patients attending our center were enrolled (Consolidation arm: 34, Induction arm:28). Their median age was 53 (27-69) years. Fifty-nine of them had MSS/pMMR type cancer (95.2%), and only three MSI-H/dMMR. Additionally, 55 patients (88.7%) had Stage III disease. The following important characteristics were distributed as follows: lower location (≤5 cm from anus, 48/62, 77.4%), deeper invasion by primary lesion (cT4 7/62, 11.3%; mesorectal fascia involved 17/62, 27.4%), and high risk of distant metastasis (cN2 26/62, 41.9%; EMVI+ 11/62, 17.7%). All 62 patients completed the SCRT and at least five cycles of ToriCAPOX, 52/62 (83.9%) completing six cycles of ToriCAPOX. Finally, 29 patients achieved cCR (46.8%, 29/62), 18 of whom decided to adopt a W&W strategy. TME was performed on 32 patients. Pathological examination showed 18 had achieved pCR, four TRG 1, and 10 TRG 2-3. The three patients with MSI-H disease all achieved cCR. One of these patients was found to have pCR after surgery whereas the other two adopted a W&W strategy. Thus, the pCR and CR rates were 56.2% (18/32) and 58.1% (36/62), respectively. The TRG 0-1 rate was 68.8% (22/32). The most common non-hematologic AEs were poor appetite (49/60, 81.7%), numbness (49/60, 81.7%), nausea (47/60, 78.3%) and asthenia (43/60, 71.7%); two patients did not complete this survey. The most common hematologic AEs were thrombocytopenia (48/62, 77.4%), anemia (47/62, 75.8%), leukopenia/neutropenia (44/62, 71.0%) and high transaminase (39/62, 62.9%). The main Grade III-IV AE was thrombocytopenia (22/62, 35.5%), with three patients (3/62, 4.8%) having Grade IV thrombocytopenia. No Grade V AEs were noted. Conclusions: SCRT-based total neoadjuvant therapy combined with toripalimab can achieve a surprisingly good CR rate in patients with LARC and thus has the potential to offer new treatment options for organ preservation in patients with MSS and lower-location rectal cancer. Meanwhile, the preliminary findings of a single center show good tolerability, the main Grade III-IV AE being thrombocytopenia. The significant efficacy and long-term prognostic benefit need to be determined by further follow-up.

Global, regional, and national burden of hypertensive heart disease among older adults in 204 countries and territories between 1990 and 2019: a trend analysis / 中华医学杂志(英文版)

BACKGROUND@#Hypertensive heart disease (HHD) poses a public health challenge, but data on its burden and trends among older adults are scarce. This study aimed to identify trends in the burden of HHD among older adults between 1990 and 2019 at the global, regional, and national levels.@*METHODS@#Using the Global Burden of Diseases study 2019 data, we assessed HHD prevalence, death, and disability-adjusted life-year (DALY) rates for individuals aged 60-89 years at the global, regional, and national levels and estimated their average annual percentage changes (AAPCs) between 1990 and 2019 using joinpoint regression analysis.@*RESULTS@#In 2019, there were 14.35 million HHD prevalent cases, 0.85 million deaths, and 14.56 million DALYs in older adults. Between 1990 and 2019, the prevalence of HHD increased globally {AAPC, 0.38 (95% confidence interval [CI], 0.36, 0.41)} with decreases observed in mortality (AAPC, -0.83 [95% CI, -0.99, -0.66]) and the DALY rate (AAPC, -1.03 [95% CI, -1.19, -0.87]). This overall global trend pattern was essentially maintained for sex, age group, and sociodemographic index (SDI) quintile except for non-significant changes in the prevalence of HHD in those aged 70-74 years and in the middle SDI quintile. Notably, males had a higher HHD prevalence rate. However, HHD-related mortality and the DALY rate were higher in females. The middle SDI quintile experienced the largest decreases in mortality and the DALY rate, with a non-significant decline in prevalence between 1990 and 2019. There were significant discrepancies in the HHD burden and its trends across regions and countries.@*CONCLUSIONS@#In the past three decades, there has been an overall increasing trend in the prevalence of HHD among older adults worldwide despite decreasing trends in mortality and the DALY rate. Better management of hypertension, and prevention and control of HHD are needed in older adults.

Association of baseline serum cholesterol with benefits of intensive blood pressure control / 中华医学杂志(英文版)

BACKGROUND@#Intensive systolic blood pressure (SBP) control improved outcomes in the Strategy of Blood Pressure Intervention in the Elderly Hypertensive Patients (STEP) trial. Whether baseline serum lipid parameters influence the benefits of intensive SBP control is unclear.@*METHODS@#The STEP trial was a randomized controlled trial that compared the effects of intensive (SBP target of 110 to <130 mmHg) and standard (SBP target of 130 to <150 mmHg) SBP control in Chinese patients aged 60 to 80 years with hypertension. The primary outcome was a composite of cardiovascular disease events. A total of 8283 participants from the STEP study were included in this post hoc analysis to examine whether the effects of the SBP intervention differed by baseline low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) concentrations.@*RESULTS@#Regardless of the randomized SBP intervention, baseline LDL-C and non-HDL-C concentrations had a J-shaped association with the hazard of the primary outcome. However, the effects of the intensive SBP intervention on the primary outcome were not influenced by baseline LDL-C level ( P for interaction = 0.80) and non-HDL-C level ( P for interaction = 0.95). Adjusted subgroup analysis using tertiles in LDL-C1 (hazard ratio [HR], 0.77; 95% confidence interval [CI], 0.52-1.13; P = 0.18), LDL-C2 (HR, 0.81; 95% CI, 0.55-1.20; P = 0.29), and LDL-C3 (HR, 0.68; 95% CI, 0.47-0.98; P = 0.04) was provided, with an interaction P value of 0.49. Similar results were showed in non-HDL-C1 (HR, 0.87; 95% CI, 0.59-1.29; P = 0.49), non-HDL-C2 (HR, 0.70; 95% CI, 0.48-1.04; P = 0.08), and non-HDL-C3 (HR, 0.67; 95% CI, 0.47-0.95; P = 0.03), with an interaction P -value of 0.47.@*CONCLUSION@#High baseline serum LDL-C and non-HDL-C concentrations were associated with increased risk of primary cardiovascular disease outcome, but there was no evidence that the benefit of the intensive SBP control differed by baseline LDL-C and non-HDL-C concentrations.@*CLINICAL TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03015311.

Severity of non-alcoholic fatty liver disease is a risk factor for developing hypertension from prehypertension / 中华医学杂志(英文版)

BACKGROUND@#There is little published evidence about the role of non-alcoholic fatty liver disease (NAFLD) in the progression from prehypertension to hypertension. This study was conducted to investigate the association of NAFLD and its severity with the risk of hypertension developing from prehypertension.@*METHODS@#The study cohort comprised 25,433 participants from the Kailuan study with prehypertension at baseline; those with excessive alcohol consumption and other liver diseases were excluded. NAFLD was diagnosed by ultrasonography and stratified as mild, moderate, or severe. Univariable and multivariable Cox proportional hazard regression was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) of incident hypertension according to the presence and 3 categories of severity of NAFLD.@*RESULTS@#During a median of 12.6 years of follow-up, 10,638 participants progressed to hypertension from prehypertension. After adjusting for multiple risk factors, patients with prehypertension and NAFLD had a 15% higher risk of incident hypertension than those without NAFLD (HR = 1.15, 95% CI 1.10-1.21). Moreover, the severity of NAFLD was associated with the incidence of hypertension, which was higher in patients with more severe NAFLD (HR = 1.15 [95% CI 1.10-1.21] in the mild NAFLD group; HR = 1.15 [95% CI 1.07-1.24] in the moderate NAFLD group; and HR = 1.20 [95% CI 1.03-1.41] in the severe NAFLD group). Subgroup analysis indicated that age and baseline systolic blood pressure may modify this association.@*CONCLUSIONS@#NAFLD is an independent risk factor for hypertension in patients with prehypertension. The risk of incident hypertension increases with the severity of NAFLD.

Causality between type 2 diabetes mellitus and age-related macular degeneration: a Mendelian randomization study / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the causality between type 2 diabetes mellitus(T2DM)and age-related macular degeneration(ARMD)based on two-sample Mendelian randomization(MR).METHODS: T2DM and ARMD samples were extracted from the FinnGen database. Inverse variance weighted(IVW)was used as the main analysis method, MR-Egger and weighted median(WM)as supplementary methods to analyze the potential relationship between them. In addition, Cochran Q test and MR-Egger intercept were also used to analyze the sensitivity, and the P-value was used as the index of research results.RESULTS: IVW showed that T2DM was associated with the incidence of exudative ARMD(OR=1.14, 95%CI 1.01～1.28, P=0.021), but it was not significantly associated with the incidence of atrophic ARMD(OR=0.96, 95%CI 0.86～1.07, P=0.554). The results of sensitivity analysis confirmed that there was no heterogeneity and pleiotropy in this study, and the results were reliable.CONCLUSION: There is a causal relationship between T2DM and exudative ARMD. Considering the high rate of blindness caused by ARMD, it is of great significance to recognize and control the risk factors of ARMD to reduce its prevalence rate and early diagnosis and treatment.

ObjectiveTo reveal the differences of the related pathogenicity gene mutations between sebaceous adenocarcinoma （SC） of scalp and sebaceous adenoma （SA） of scalp on whole exome level. MethodsWhole exome sequencing was performed on a SC sample and a SA sample by Illumina Hiseq 2500 platform. Suspicious single nucleotide variation sites were selected for mutation conservation and functional analysis. SciClone was used to track subclone evolution and clonal map information was obtained for each tumor sample. The high-frequency significant gene mutations in the tumor sample were screened by MutSigCV software， and compared with the known driver genes. ResultsTwo driver genes TFDP1 and ACVR1B harboring mutations in scalp SC compared to SA were found. ConclusionsThe finding of mutation in driver genes TFDP1 and ACVR1B should be confirmed in a large cohort， which might reveal the mechanism of scalp SC development and find a therapeutic target for SC.

Factors associated with overweight or obesity in community patients with schizophrenia in Shanghai / 上海预防医学

ObjectiveTo investigate the prevalence of overweight or obesity in community patients with schizophrenia in Shanghai and to explore the related factors. MethodsStratified cluster sampling method was used and the general condition， physical examination and laboratory examination data of patients with schizophrenia who voluntarily participated in 2020 free health examination of National Basic Public Health Service were analyzed. ResultsA total of 3 200 patients were included into the study ，and the prevalence of overweight and obesity was 36.75% and 17.19%， respectively. Multivariate logistic regression analysis indicated that age between 40 and 60 （OR=1.333， 95%CI： 1.030‒1.724）， intake of first-generation antipsychotics （OR=1.413， 95%CI： 1.112‒1.796）， intake of second-generation antipsychotics （OR=1.573， 95%CI： 1.288‒1.921）， high-normal blood pressure （OR=1.549， 95%CI： 1.245‒1.927）， high-abnormal blood pressure （OR=2.824， 95%CI： 2.204‒3.619）， elevated ALT （OR=1.874， 95%CI： 1.386‒2.535）， elevated FBG （OR=1.270， 95%CI： 1.066‒1.513）， and elevated TG （OR=1.652， 95%CI： 1.335‒2.044） were the related factors that associated overweight or obesity in patients with schizophrenia. ConclusionOverweight and obesity are highly prevalent among community patients with schizophrenia in Shanghai. Age between 40 and 60， taking first-generation and second-generation antipsychotics， blood pressure higher than 120/80 mmHg， elevated ALT， elevated FBG， and elevated TG are associated with overweight or obesity in patients with schizophrenia. To provide personalized health guidance， medical staff in primary health care institutions should pay more attention to high-risk groups of overweight and obesity in schizophrenia patients at annual physical examination.

Related factors of relapse based on positive and negative syndrome scale among schizophrenics in Shanghai communities / 上海预防医学

ObjectiveTo explore the relapse status based on the positive and negative syndrome scale （PANSS Scale） and related factors of schizophrenics in Shanghai communities， and to analyze the association between socio demographic characteristics， lifestyles， clinical characteristics and relapse. MethodsA dynamic cohort prospective study design was used in this study. From March 2018 to February 2019， a total of 189 schizophrenics in Xuhui， Hongkou， Changning， Jiading， Songjiang and Baoshan districts were enrolled successively. Baseline questionnaires were conducted through face-to-face interviews at baseline， which contained social demographic information， lifestyle information and clinical information. A follow-up was conducted every 2 weeks for a measurement of PANSS Scale for a total of 6 months. Relapse was assessed by a PANSS score increase of ≥25% from baseline （or an increase of 10 points or more if the baseline score was ≤40 points）. Univariate and multivariate Cox regression models were used to analyze the associations between relapse status （assessed by PANSS Scale） and socio demographic characteristics， lifestyles， and clinical characteristics， respectively. ResultsA total of 165 community schizophrenics completed baseline and follow-up surveys， with a loss to follow-up rate of about 12.7%. After exclusion of sociodemographic and clinical information deficits， 132 patients were included in the analysis totally， with an average age of 48.18±12.67 years， among whom 41.67% were male. Totally 33 patients relapsed during the 6-month follow-up period， with a relapse rate of 25.0%. After adjusting for gender， family history， age， employment， education， marital status， smoking， drinking， exercise frequency， medication compliance， insight， social function， violence history， stress recent events， adverse drug reactions and baseline scores of PANSS Scale， risk factors of relapse included the following four factors： age below 40 years （HR=4.47， 95%CI： 1.15-17.40）， primary school or below （HR=7.11， 95%CI： 1.54-32.83）， unemployed （HR=8.34， 95%CI： 1.78-38.98）， and adverse drug reactions （HR=5.02， 95%CI： 1.75-14.37）. ConclusionWe should pay attention to the risk factors such as age， education， employment and adverse drug reactions， in order to identify high-risk patients and to conduct timely interventions during the relapse management of schizophrenics in Shanghai community.

Application of PET-LINAC in Biology-guided Radiotherapy / 中国医疗器械杂志

Biology-guided radiotherapy (BgRT) is a novel technique of external beam radiotherapy, combining positron emission tomography-computed tomography (PET-CT) with a linear accelerator (LINAC). The key innovation is to utilize PET signals from tracers in tumor tissues for real-time tracking and guiding beamlets. Compared with a traditional LINAC system, a BgRT system is more complex in hardware design, software algorithm, system integration and clinical workflow. RefleXion Medical has developed the world's first BgRT system. Nevertheless, its actively advertised function, PET-guided radiotherapy, is still in the research and development phase. In this review study, we presented a number of issues related to BgRT, including its technical advantages and potential challenges.

Self-reported quality of life in patients with coronary heart disease and analysis of the associated factors / 中华内科杂志

Objective: To investigate the quality of life and associated factors in patients with coronary heart disease (CHD) in China. Methods: A cross-sectional study of 25 provinces and cities in China was performed from June to September 2020. A questionnaire was used to collect the socio-demographic and clinical information of patients with CHD, while the European Five-dimensional Quality of Life Scale (EQ-5D) was used to assess the quality of life. Multiple linear regression model was performed to analyze the associated factors. Results: The median age of the 1 075 responders was 60 (52, 67) years, and 797 (74.1%) were men. The EQ-5D and EQ-VAS indices were 0.7 (0.5, 0.8) and 60.0 (40.0, 80.0). Among the five dimensions in the quality of life scale, the frequency of anxiety/depression was the highest (59.8%), while problems in self-care was the lowest (35.8%). In the multiple linear regression model, female, increasing age, obesity, comorbidity(ies), anxiety/depression, social media channels, and receiving the CABG therapy were associated with the lower EQ-5D index (all P<0.05). In addition, increasing age, obesity, comorbidity (ies), depression, anxiety and depression, social media channels, and receiving the CABG therapy were associated with lower EQ-VAS index (all P<0.05). Conclusion: Over half of the patients with CHD in China have a low quality of life, which is related to gender, age, obesity, treatment pathway, the presence or absence of comorbidity (ies), and psychological state. In addition to managing the adverse effects of traditional socio-demographic factors on the quality of life, clinical practices should pay attention to the psychological state of patients. Moreover, establishing a WeChat group for doctor-patient communication could improve the quality of life of CHD patients.

Clinical and genetic characteristics of children with dopa-responsive dystonia caused by tyrosine hydroxylase gene variations / 中华儿科杂志

Objective: To explore the clinical and genetic characteristics of children with dopa-responsive dystonia (DRD) caused by tyrosine hydroxylase (TH) gene variations. Methods: Clinical data of 9 children with DRD caused by TH gene variations diagnosed in the Department of Children Rehabilitation, the Third Affiliated Hospital of Zhengzhou University from January 2017 to August 2022 were retrospectively collected and analyzed, including the general conditions, clinical manifestations, laboratory tests, gene variations and follow-up data. Results: Of the 9 children with DRD caused by TH gene variations, 3 were males and 6 were females. The age at diagnosis was 12.0 (8.0, 15.0) months. The initial symptoms of the 8 severe patients were motor delay or degression. Clinical symptoms of the severe patients included motor delay (8 cases), truncal hypotonia (8 cases), limb muscle hypotonia (7 cases), hypokinesia (6 cases), decreased facial expression (4 cases), tremor (3 cases), limb dystonia (3 cases), diurnal fluctuation (2 cases), ptosis (2 cases), limb muscle hypertonia (1 case) and drooling (1 case). The initial symptom of the very severe patient was motor delay. Clinical symptoms of the very severe patient included motor delay, truncal hypotonia, oculogyric crises, status dystonicus, hypokinesia, decreased facial expression, and decreased sleep. Eleven TH gene variants were found, including 5 missense variants, 3 splice site variants, 2 nonsense variants, and 1 insertion variant, as well as 2 novel variants (c.941C>A (p.T314K), c.316_317insCGT (p.F106delinsSF)). Nine patients were followed up for 40 (29, 43) months, and no one was lost to follow-up. Seven of the 8 severe patients were treated by levodopa and benserazide hydrochloride tablets and 1 severe patient was treated by levodopa tablets. All the severe patients responded well to levodopa and benserazide hydrochloride tablets or levodopa tablets. Although the weight of the patients increased and the drug dosage was not increased, the curative effect remained stable and there was no obvious adverse reaction. One severe patient developed dyskinesia in the early stage of treatment with levodopa and benserazide hydrochloride tablets and it disappeared after oral administration of benzhexol hydrochloride tablets. Until the last follow-up, motor development of 7 severe patients returned to normal and 1 severe patient still had motor delay due to receiving levodopa and benserazide hydrochloride tablets for only 2 months. The very severe patient was extremely sensitive to levodopa and benserazide hydrochloride tablets and no improvement was observed in this patient. Conclusions: Most of the DRD caused by TH gene variations are severe form. The clinical manifestations are varied and easily misdiagnosed. Patients of the severe patients responded well to levodopa and benserazide hydrochloride tablets or levodopa tablets, and it takes a long time before full effects of treatment become established. Long-term effect is stable without increasing the drug dosage, and no obvious side effect is observed.

Application of membrane anatomy in hepatopancreatobiliary and splenic surgery / 中华外科杂志

Understanding of a variety of membranous structures throughout the body,such as the fascia,the serous membrane,is of great importance to surgeons. This is especially valuable in abdominal surgery. With the rise of membrane theory in recent years,membrane anatomy has been widely recognized in the treatment of abdominal tumors,especially of gastrointestinal tumors. In clinical practice. The appropriate choice of intramembranous or extramembranous anatomy is appropriate to achieve precision surgery. Based on the current research results,this article described the application of membrane anatomy in the field of hepatobiliary surgery,pancreatic surgery,and splenic surgery,with the aim of blazed the path from modest beginnings.

Population structure of food-borne Staphylococcus aureus in China / 中华流行病学杂志

Objective: To understand the population structure of food-borne Staphylococcus (S.) aureus in China. Methods: Whole genome sequencing was used to analyze 763 food-borne S. aureus strains from 16 provinces in China from 2006 to 2020. Multilocus sequence typing (MLST), staphylococcal protein A gene (spa) typing, and staphylococcal chromosome cassettemec (SCCmec) typing were conducted, and minimum spanning tree based on ST types (STs) was constructed by BioNumerics 7.5 software. Thirty-one S. aureus strains isolated from imported food products were also included in constructing the genome phylogenetic tree. Results: A total of 90 STs (20 novel types) and 160 spa types were detected in the 763 S. aureus isolates. The 72 STs (72/90, 80.0%) were related to 22 clone complexes. The predominant clone complexes were CC7, CC1, CC5, CC398, CC188, CC59, CC6, CC88, CC15, and CC25, accounting for 82.44% (629/763) of the total. The STs and spa types in the predominant clone complexes changed over the years. The methicillin-resistant S. aureus (MRSA) detection rate was 7.60%, and 7 SCCmec types were identified. The ST59-t437-Ⅳa (17.24%, 10/58), ST239-t030-Ⅲ (12.07%, 7/58), ST59-t437-Ⅴb (8.62%, 5/58), ST338-t437-Ⅴb (6.90%, 4/58) and ST338-t441-Ⅴb (6.90%, 4/58) were the main types in MRSA strains. The genome phylogenetic tree had two clades, and the strains with the same CC, ST, and spa types clustered together. All CC7 methicillin sensitive S. aureus strains were included in Clade1, while 21 clone complexes and all MRSA strains were in Clade2. The MRSA strains clustered according to the SCCmec and STs. The strains from imported food products in CC398, CC7, CC30, CC12, and CC188 had far distances from Chinese strains in the tree. Conclusions: In this study, the predominant clone complexes of food-borne strains were CC7, CC1, CC5, CC398, CC188, CC59, CC6, CC88, CC15, and CC25, which overlapped with the previously reported clone complexes of hospital and community-associated strains in China, suggesting that close attention needs to be paid to food, a vehicle of pathogen transmission in community and food poisoning.

Complicated Bosworth fracture-dislocation: A case report and review of the literature / 中华创伤杂志(英文版)

Bosworth fracture and dislocation is relatively rare, accounting for about 1% of ankle fractures. It is characterized by the proximal fibula fracture embedded in the posterolateral distal tibia. Due to an insufficient understanding of this fracture, it is easy to cause missed diagnosis and misdiagnosis in clinical practice. Due to the insertion of the fracture, it is challenging to perform closed reduction, and improper treatment is easy to cause complications. Surgical treatment is recommended for this type of fracture. In order to improve the understanding of orthopedic surgeons about Bosworth fracture and dislocation, this paper reports the diagnosis and treatment of 2 cases of Bosworth fracture and dislocation, and reviews the literature on Bosworth fracture's mechanism, diagnosis, classification, complications, and treatment options in recent years.

Stress level of people seeking psychological counseling and its related factors in the early stage of COVID⁃19 outbreak in Shanghai / 上海预防医学

ObjectiveTo understand the stress level of people seeking psychological counseling under the coronavirus disease 2019 （COVID⁃19） pandemic and to explore its related factors. MethodsAn online survey was conducted on 1 194 people who sought psychological counseling in Shanghai through the “health cloud” psychological counseling service platform. The questionnaire included demographic information，lifestyle and stress during the COVID-19 pandemic. ResultsParticipants with low，medium，high and very high stress levels accounted for 33.1% （395/1 194），34.6% （413/1 194），25.4% （303/1 194） and 7.0% （83/1 194），respectively. Women and participants aged 18 to 30 years had higher stress levels（Z=-5.368，P<0.001； Z=35.822，P<0.001） compared with other groups. Factors contributing to the rise in stress included reading too much information about COVID-19 （OR=2.057，95%CI：1.012‒4.181），large changes in sleep state （OR=3.496，95%CI：1.669‒7.325），lack of hobbies and interests （OR=2.852，95%CI：1.252‒6.500），and prone to anxiety/irritability/sadness （OR=4.098，95%CI：1.772‒9.480）. Conclusionpeople who sought psychological counseling show high levels of psychological stress during the COVID-19 pandemic. We should pay more attention to the vulnerable groups with the following characteristics： women，18‒30 years old， residents who pay too much attention to the pandemic information，sleep less， and almost lose interest in hobbies， and easily become anxious/irritable/sad.

Qili Qiangxin, a compound herbal medicine formula, alleviates hypoxia-reoxygenation-induced apoptotic and autophagic cell death via suppression of ROS/AMPK/mTOR pathway in vitro / 中西医结合学报

OBJECTIVE@#Qili Qiangxin (QLQX), a compound herbal medicine formula, is used effectively to treat congestive heart failure in China. However, the molecular mechanisms of the cardioprotective effect are still unclear. This study explores the cardioprotective effect and mechanism of QLQX using the hypoxia-reoxygenation (H/R)-induced myocardial injury model.@*METHODS@#The main chemical constituents of QLQX were analyzed using high-performance liquid chromatography-evaporative light-scattering detection. The model of H/R-induced myocardial injury in H9c2 cells was developed to simulate myocardial ischemia-reperfusion injury. Apoptosis, autophagy, and generation of reactive oxygen species (ROS) were measured to assess the protective effect of QLQX. Proteins related to autophagy, apoptosis and signalling pathways were detected using Western blotting.@*RESULTS@#Apoptosis, autophagy and the excessive production of ROS induced by H/R were significantly reduced after treating the H9c2 cells with QLQX. QLQX treatment at concentrations of 50 and 250 μg/mL caused significant reduction in the levels of LC3II and p62 degradation (P < 0.05), and also suppressed the AMPK/mTOR signalling pathway. Furthermore, the AMPK inhibitor Compound C (at 0.5 μmol/L), and QLQX (250 μg/mL) significantly inhibited H/R-induced autophagy and apoptosis (P < 0.01), while AICAR (an AMPK activator, at 0.5 mmol/L) increased cardiomyocyte apoptosis and autophagy and abolished the anti-apoptotic effect of QLQX. Similar phenomena were also observed on the expressions of apoptotic and autophagic proteins, demonstrating that QLQX reduced the apoptosis and autophagy in the H/R-induced injury model via inhibiting the AMPK/mTOR pathway. Moreover, ROS scavenger, N-Acetyl-L-cysteine (NAC, at 2.5 mmol/L), significantly reduced H/R-triggered cell apoptosis and autophagy (P < 0.01). Meanwhile, NAC treatment down-regulated the ratio of phosphorylation of AMPK/AMPK (P < 0.01), which showed a similar effect to QLQX.@*CONCLUSION@#QLQX plays a cardioprotective role by alleviating apoptotic and autophagic cell death through inhibition of the ROS/AMPK/mTOR signalling pathway.
