ABSTRACT
To assess the reliability, validity and responsiveness of the Chinese version of the atopic dermatitis control tool (ADCT). After this study obtained authorization for the Chinese version of the ADCT scale. 114 patients with atopic dermatitis were enrolled from the Department of Dermatology, Peking University First Hospital using convenience sampling from October 2022. Patients were surveyed using the General Information Questionnaire, Chinese version of ADCT, patient-oriented eczema measure (POEM),peak pruritus numerical rating scale (PP-NRS),dermatology life quality index (DLQI) and the global patient self-assessment for disease severity. Mann-Whitney rank sum test and Spearman correlation analysis were used for item analysis; content validity was assessed using content validity index (CVI); exploratory factor analysis was used to assess structural validity; Cronbach' alpha coefficient was used to assess internal consistency; Spearman correlation analysis was used to assess the correlation of ADCT with other scales to assess external responsiveness. The results showed that all items were retained by item analysis. I-CVI was 0.9-1, and S-CVI/Average was 0.983; the scale extracted one common factor by factor analysis, the cumulative variance explanation rate was 77.927%; the Cronbach' alpha coefficient of the scale was 0.937; the correlation coefficients of the Chinese version of ADCT with POEM, PP-NRS, and DLQI were 0.805, 0.861, and 0.709 respectively. In conclusion, the Chinese version of the ADCT has adequate reliability, validity and responsiveness, and is suitable for measuring disease control in Chinese patients with atopic dermatitis.

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.
ABSTRACT
ABSTRACT Background The purpose is to compare the efficacy and safety of mini percutaneous nephrolithotomy (mini-PCNL) versus standard percutaneous nephrolithotomy (standard-PCNL) in patients with renal stones >2cm. Materials and Methods A systematic literature search was conducted in PubMed, Web of Science, Scopus, and the Cochrane Library databases to identify relevant studies before March 8, 2021. Stone-free rate (SFR), operation time, fever rate, hemoglobin drop, blood transfusion rate, and hospitalization time were used as outcomes to compare mini-PCNL and standard-PCNL. The meta-analysis was performed using the Review Manager version 5.4. Results Seven randomized controlled trials were included in our meta-analysis, involving 1407 mini-PCNL cases and 1436 standard-PCNL cases. Our results reveal that, for renal stones >2cm, mini-PCNL has a similar SFR (risk ratio (RR)=1.01, 95% confidence interval (CI): 0.98 to 1.04, p=0.57) and fever rate (RR=1.22, 95% CI: 0.97-1.51, p=0.08). Standard-PCNL was associated with a significantly shorter operating time (weighted mean difference (WMD)=8.23, 95% CI: 3.44 to 13.01, p <0.01) and a longer hospitalization time (WMD=-20.05, 95% CI: -29.28 to -10.81, p <0.01) than mini-PCNL. Subgroup analysis showed hemoglobin drop and blood transfusion for 30F standard-PCNL were more common than mini-PCNL (WMD=-0.95, 95% CI: -1.40 to -0.50, p <0.01; RR=0.20, 95% CI: 0.07 to 0.58, p <0.01). Conclusion In the treatment of >2cm renal stones, mini-PCNL should be considered an effective and reliable alternative to standard-PCNL (30F). It achieves a comparable SFR to standard-PCNL, but with less blood loss, lower transfusion rate, and shorter hospitalization. However, the mini-PCNL does not show a significant advantage over the 24F standard-PCNL. On the contrary, this procedure takes a longer operation time. Trial registration This meta-analysis was reported consistent with the PRISMA statement and was registered on PROSPERO, with registration number 2021CRD42021234893.
ABSTRACT
Objective To study the correlation between the abdominal wall subcutaneous fat thickness and heart weight, so as to provide reference for prediction methods of normal range of heart weight that is suitable for autopsy in China. Methods The forensic pathology autopsy cases accepted by Center for Medicolegal Expertise of Sun Yat-sen University from 1998 to 2017 were collected. Then the exclusion criteria were determined, and according to them the total case group was selected, and the 6 disease groups and the normal group were further selected from the total case group. The rank sum test was used to compare the heart weight of the normal group and the disease groups to determine the influence of diseases on heart weight. Then the Spearman rank correlation analysis of abdominal wall subcutaneous fat thickness and heart weight in different genders and different ages in the total case group and the normal group was conducted to get the correlation coefficient （rs）. Results In the total case group, correlation between abdominal wall subcutaneous fat thickness and heart weight was shown in males of all ages （P<0.05）; while in females, the correlation had no statistical significance （P>0.05） in 15-<20 age and 50-<60 age, but was statistically significant （P<0.05） in other age groups. For the males in the normal group, rs was respectively 0.411, 0.541 and 0.683 in the 15-<40 age, the 40-<60 age, and the ≥60 age. For the females, rs was respectively 0.249 and 0.317 in the 15-<40 age and the 40-<60 age. The correlation in the ≥60 age had no statistical significance（P>0.05）. Conclusion In the general population and the normal population, abdominal wall subcutaneous fat thickness is correlated with the heart weight of males. It is of significance to include the abdominal wall subcutaneous fat thickness in the prediction of normal range of heart weight for males in China.

In the past, coronavirus caused two serious human-to-human pandemics in the world, including severe acute respiratory syndrome （SARS） and Middle East respiratory syndrome （MERS）. In late 2019, coronavirus disease 2019 （COVID-19） caused another major global public health event. Due to the strong infectivity of novel coronavirus, it is difficult to carry out the autopsy of related death cases widely. This paper reviews the previous status of the pathogen detection related to the autopsy of coronavirus infection diseases, and introduces the ongoing detection methods of novel coronavirus in clinical practice, in order to provide reference for the pathogen detection and study related to autopsy of COVID-19.

The outbreak of COVID-19 has exposed many shortcomings in disease control and prevention system (DCPS) of China. Resolving the problems and strengthening the DCPS became the top priority in China’s public policy agenda. This paper revealed the problems of the system regarding policy-making, regulations, operation mechanism and staff, and proposed several strategies from three aspects of legal construction, management system, and operation mechanism, including: 'Prevention first' should be incorporated into the national legal system, all the departments should be engaged in 'Healthy China 2030' initiative, laws and regulations should be amended, new disease prevention and control management institutions should be set up, a high-quality professional team should be retained, the regional health information exchange channels should be strengthened, the coordinated mechanism for disease prevention and control should be normalized, the long-term investment mechanism should be established, and the equipment renewal and reserve system should be improved.
ABSTRACT
OBJECTIVE@#To assess the relationship between yogurt intake and mortality risk from prospective cohort studies.@*METHODS@#The PubMed, EMBASE, and Web of Science databases were searched for all records related to yogurt intake and mortality risk [all-cause or cardiovascular disease (CVD) or cancer mortality] before October 1, 2018. The Newcastle-Ottawa Quality Scale was used to estimate the quality of all eligible articles. The results of the highest and lowest categories of yogurt intake in each study were collected and the effect size was pooled using a random effects model. The dose-response analysis was calculated using the generalized least squares trend estimation model.@*RESULTS@#Eight eligible cohort studies were included in this meta-analysis. There were 235,676 participants in the 8 studies, and the number of deaths was 14,831. Compared with the lowest category, the highest category of yogurt intake was not significantly related with all-cause mortality [hazard ratio (HR)=0.93; 95% confidence interval (CI): 0.85, 1.01], CVD mortality (HR=0.92; 95% CI: 0.81, 1.03) and cancer mortality (HR=0.97; 95% CI: 0.83, 1.12). These studies were homogenous, since the homogeneity test showed that I was 28.7%, 15.1% and 11.8%, respectively. However, yogurt intake ⩾200 g/d was significantly associated with a lower all-cause mortality (HR=0.88; 95% CI: 0.80, 0.96) and CVD mortality (HR=0.87; 95% CI: 0.77, 0.99) in the subgroup analysis. The dose-response analysis showed that yogurt intake of 200 g/d was inversely associated with all-cause mortality (P=0.041, HR=0.95, 95% CI: 0.92, 1.00) and CVD mortality (P=0.009, HR=0.92, 95% CI: 0.86, 0.98), and all of which were linear relationship (P>0.05).@*CONCLUSIONS@#This review provided the evidence regarding yogurt intake can reduce all-cause and CVD mortality. Although some positive findings were identified, more high-quality cohort studies and randomized controlled trials are warranted on a possible protective effect of yoghurt on health.
ABSTRACT
Objective:To explore the clinical effect of endoscopic assisted or microscopical transsphenoidal surgery in the treatment of different grades of invasive pituitary tumors and the measures to reduce complications.Methods:From January 2016 to June 2019, 87 patients with pituitary tumor admitted to the neurosurgery of Tangshan People′s Hospital of Hebei Province were selected as the study objects for retrospective analysis. Among them, 42 patients were included in the endoscopic group and 45 patients were included in the endoscopic group. To compare the related indexes and clinical effects of two different surgical methods, and to analyze the treatment strategies to reduce the common postoperative complications.Results:The amount of intraoperative bleeding, the time needed for operation and the hospital stay of patients in endoscopic group were significantly less or shorter than those in microscopical group(intraoperative bleeding volume: (66.19±9.55) ml and (79.78±11.68) ml; operation time: (93.93±9.53) min and (103.33±9.23) min; hospitalization time: (7.71±1.53) d and (10.16±1.33) d). The difference was statistically significant (T values were 5.92, 4.67, 7.94, all P< 0.01). There was no significant difference between the two groups ( P= 0.577). There were 2 cases (4.8%) of cerebrospinal fluid leakage in endoscopic group and 12 cases (26.7%) in microscopical group. The difference between the two groups was statistically significant(χ 2=5.67, P< 0.05). There were 7 cases (16.7%) of diabetes insipidus in endoscopic group and 22 cases (48.9%) in microscopical group. The difference between the two groups was statistically significant (χ 2=5.19, P< 0.05). Conclusion:The curative effect of endoscopic transsphenoidal resection of pituitary tumor is similar to that of microscopical resection of pituitary tumor. The patients recover quickly, have fewer complications, and have a short hospital stay.
ABSTRACT
On the basis of systematic evaluation of 32 provincial capital cities and municipalities in their capacity for preventing and controlling emerging infectious diseases, focus analysis is made on Wuhan in relation to its advantages and disadvantages as follows:There has been a legal basis for epidemic prevention according to law, but it has not translated into effective action.There has been an organizational basis for responding to epidemic, but coordination mechanism has not been effectively established.The management mechanism has been complete, but the division of responsibilities among different departments has not been clear.The monitoring network has been set up, but its role of "predictive warning" has not been played.Insufficiency of public health service delivery was observed owing to lack of financial investment.In cities of China, advantages and disadvantages have been both existent in their capacity to prevent and control of emerging infectious disease.We should be vigilant in this regard. It is imperative to "fill defects, stop leaks and strengthen weakness".There is a Chinese saying:"It is not too late to mend a fold after the sheep have been stolen".

ABSTRACT
Objective@#To clarify the effect of astragalus polysaccharide （AP） on insulin resistance model of HepG2 cells induced by hyperinsulinemia and its underlying molecular mechanism in lipid metabolism and oxidative stress.@*Methods@#HepG2 cells were divided into three groups： the control group was treated without any intervention; the model group was treated with 200 μL cell culture medium containing 10-6 mol/L insulin for 48 hours to build an insulin resistance model; the AP group was treated with optimal concentration of AP based on an insulin resistance model. After 24 hours, the concentration of H2O2 and the expression of PPARγ in each group were detected. @*Results@#AP could improve the survival rate of insulin-resistant HepG2 cells in a dose-dependent manner. The highest survival rate of the cells was （118.26±1.17）% with 10 μM AP. The concentration of H2O2 in the AP group was （0.82±0.09） μM, which was lower than （1.30±0.16） μM in the model group （P<0.05）, but was close to （0.78±0.09） μM in the control group （P>0.05）. The relative mRNA expression of PPARγ in the AP group was 0.96±0.04, which was higher than 0.51±0.05 in the model group （P<0.05）, but was close to 1.00±0.11 in the control group （P>0.05）.@*Conclusions@#In the insulin resistance model in vitro, AP can significantly increase the cell survival rate, reduce intracellular H2O2 concentration, and promote the expression of PPARγ. The mechanism may be related to lipid metabolism.
ABSTRACT
Autopsy is of great significance to the elucidation of the pathological changes, pathogeneses and causes of death of corona virus disease 2019 （COVID-19） and can provide theoretical basis for more scientific and accurate prevention and control of the outbreak. Based on related laws and regulations, such as the Law of the People's Republic of China on Prevention and Control of Infectious Diseases, the clinical manifestations and epidemiological characteristics of COVID-19, and the related guidelines on the prevention and control of the outbreak, combined with the practical work of forensic pathology examination, the Guide to the Forensic Pathology Practice on Death Cases Related to Corona Virus Disease 2019 （COVID-19） （Trial Draft） has been developed. This guide includes information on the background investigation of the cases, autopsy room requirements, personal prevention and protections, external examinations, autopsy, auxiliary examinations, and so on. This guide can be used as a reference by forensic and pathological examination institutions, as well as examination staff.

@#Objective To investigate the feasibility of animal model of the reconstruction of right ventricular outflow tract in rats. Methods A total of 15 female Sprague-Dawley (SD) rats underwent right ventricular outflow tract reconstruction surgery. Before the operation, the collagen scaffolds were treated with g 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride chemistry (EDC), and seeded with human bone marrow stem cells (h-MSCs). Three days after the surgery, 3 rats were randomly sacrificed to evaluate the transmural resection of right ventricular outflow tract. One or 3 months later, other 3 rats at each timepoint were sacrificed, stained with Masson’s Trichrome to observe the degradation of scaffold. Furthermore, 4 weeks after the surgery, 4 rats were sacrificed and the hearts were sliced. Anti-human mitochondria staining was used to identify the survival of seeding cells. Results The transmural resection of right ventricular outflow tract was feasible in rats at an acceptable mortality (13.3%). After EDC treatment, the degradation rate of collagen scaffold was extended greatly. The seeding cells were detected by anti-mitochandria immunofluorescent staining in all patches 4 weeks after the operation. Conclusion Rat model of right ventricular outflow tract reconstruction could be a stable, reliable and economical screening model for engineered heart tissue research.

ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical efficiency and safety of two-micron laser resection of the prostate-tangerine technique (TmLRP-TT) for the treatment of large-volume ( > 70 ml) prostate in patients with benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>This retrospective analysis included 80 BPH patients with the prostatic volume larger than 70 ml, all treated by TmLRP-TT. We comparatively analyzed the levels of hemoglobin and serum sodium before and after surgery, recorded intra- and post-operative com- plications, and followed up the patients at 6 and 12 months after operation for International Prostate Symptom Score (IPSS), quality of life (QOL), maximum flow rate (Qmax), and postvoid residual urine volume (PVR).</p><p><b>RESULTS</b>All the operations were successfully completed. The mean hemoglobin decreased (0.68 +/- 0.43) g/dl intraoperatively, but no apparent reduction was observed in serum sodium. Lower urinary tract symptoms were relieved significantly in all the cases. At 12 months after surgery, IPSS was decreased by 73.89% as compared with the baseline (20.03 +/- 6.9 vs 5.23 +/- 3.59), QOL by 64.55% (4.09 +/- 1.19 vs 1.45 +/- 1.36), and PVR by 79.30% (97.31 +/- 57.90 vs 20.14 +/- 24.20 ml), while Qmax increased by 140.42% ([8.04 +/- 3.62] vs [19.33 +/- 3.28] ml/s). The incidence of complications was low either intraoperatively or during the 12 months after operation.</p><p><b>CONCLUSION</b>TmLRP-TT is a safe and effective surgical endoscopic approach to the treatment of large-volume prostate in BPH patients.</p>

<p><b>OBJECTIVE</b>To study the effects of sodium tanshinone II A sulfonate (STS) on proliferation of fibroblasts (Fbs) in human hypertrophic scar (HS), the mRNA and protein expressions of transforming growth factor beta 1 (TGF-β1) and alpha smooth muscle actin (α-SMA), and to investigate the scar inhibition mechanism of STS.</p><p><b>METHODS</b>Fbs were isolated from HS tissues that were removed from eight patients after burn injury, and they were cultured in vitro. Cells from the 3rd to the 6th passages were used in the experiment. Fbs were divided into control group and experimental group according to the random number table, and cells in the experimental group was divided into 0.050, 0.075, 0.100, 0.125, 0.150, 0.200 mg/mL STS subgroups. Cells in each subgroup were cultured with the corresponding concentration of STS, and cells in control group were cultured in equal volume of serum-free medium. After being cultured for 24 and 48 h, cell morphology was observed with inverted phase contrast microscope; cell proliferation was determined with MTT method and the proliferation inhibition rate (IR) was calculated. After being cultured for 48 h, the protein levels of TGF-β1 and α-SMA were determined with Western blotting; the mRNA expressions of TGF-β1 and α-SMA were determined with RT-PCR (no 0.200 mg/mL STS subgroup was set for these two indicators). Data were processed with factorial analysis of variance; differences between groups were processed with LSD test or Games-Howell test for unequal variances.</p><p><b>RESULTS</b>(1) Fbs grew well in control group, but reduction in adherence and disorderly arranged Fbs were observed in experimental group. The cells in experimental group became smaller and round, with increasing intracellular particles and necrosis. A large amount of necrotic debris of cells was observed in 0.200 mg/mL STS subgroup. (2) The absorbance value of Fbs in each experimental subgroup was significantly lower than that in control group (with P values all below 0.01). Along with the increase in the concentration of STS and extension of culture time, the IR value increased, showing a certain degree of time-concentration dependence. After being cultured with STS for 24 and 48 h, IR values of cells in the experimental subgroups were respectively 23.58%, 32.11%, 37.56%, 57.98%, 79.53%, 96.69% and 34.72%, 38.48%, 47.62%, 64.40%, 89.70%, 98.01%. (3) Except for the 0.050 mg/mL STS subgroup, the protein levels of TGF-β1 and α-SMA in the other subgroups were significantly lower than those in control group (with F values respectively 57.674, 47.795, P values all below 0.001). The protein levels of TGF-β1 and α-SMA reached the nadir in 0.150 mg/mL STS subgroup, respectively 0.34 ± 0.06, 0.33 ± 0.07. The relative expression amounts of TGF-β1 and α-SMA mRNA in the experimental subgroups were obviously decreased compared with those in control group (with F values respectively 68.548, 47.522, P values all below 0.001), which was most significant in 0.150 mg/mL STS subgroup, with TGF-β1 mRNA and α-SMA mRNA respectively 0.39 ± 0.07 and 0.42 ± 0.08.</p><p><b>CONCLUSIONS</b>STS can inhibit the proliferation of Fbs, reduce the protein and mRNA expressions of TGF-β1 and α-SMA, which may be beneficial to ameliorate the formation and contracture of HS, and it is assumed as a potential drug for treating scars.</p>

ABSTRACT
We report two patients with unilateral vertical retraction syndrome. Magnetic resonance imaging (MRI) of the orbits of the two cases showed similar size and location of the orbital structure, but with dramatically different strabismus type. MRI sagittal reconstruction of the orbits suggested that abnormal muscle tissue arised from the inferior rectus, which might be associated with retraction and narrowing of the palpebral fissure and atypical strabismus as well.
