Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

Objective: To examine the prevalence and trend of tobacco and e-cigarettes uses and identify the influencing factors for smoking behavior in junior middle school students in Shanghai, and provide data support and scientific basis for the development of tobacco control intervention strategy in adolescents. Methods: Multi-stage stratified random sampling method was used to select junior middle school students in 8 districts and 10 districts in Shanghai in 2013 and in 2019 respectively. Information about tobacco and e-cigarettes uses in the students were collected by using self-administrated questionnaire. The prevalence of tobacco and e-cigarettes uses were calculated, the difference between two years was compared with χ2 test. The influencing factors were identified by multivariate logistic regression analysis. Results: In 2019, the current smoking rate was 0.6% in junior middle school students in Shanghai, and the smoking attempt rate was 2.9%, both were lower than the levels in 2013 (0.7% and 6.9%). The current use rate of e-cigarettes was 0.6% in 2019,with no significant change compared with 2013 (0.6%). The proportion of the students who had heard of e-cigarettes in 2019 (78.4%) was higher than that in 2013 (47.2%). In 2019, the second-hand smoke (SHS) exposure rate at home, in both indoor and outdoor public places and on public transportations was 72.5%, which was slightly lower than the level in 2013 (73.0%), the differences were all significant (P<0.05). In 2019, the students seeing close friend smoking (OR=27.381, 95%CI: 12.037-62.287), seeing someone smoking in school (OR=2.477, 95%CI: 1.155-5.312), believing that SHS may not be harmful (OR=8.471, 95%CI: 1.464-49.005) had higher possibility of smoking. Being aged ≥15 years (compared with being aged ≤12 years, OR=8.688, 95%CI: 1.922-39.266), exposure to SHS in outdoor public place (OR=8.608, 95%CI: 1.048-70.692), close friend smoking (OR=8.115, 95%CI: 1.754-37.545) were positively associated with e-cigarettes use, and believing that smoking results in uncomfortable social contact [compared with believing that smoking results in comfortable social contact (OR=0.105,95%CI: 0.018-0.615)] were negatively associated with e-cigarettes use, the difference was significant (P<0.05). Conclusion: The prevalence of tobacco and e-cigarette uses in junior middle school students in Shanghai remained at a low level in recent years. The SHS exposure rate in junior middle school students is high. Smoking behavior of junior middle school students is closely related to personal attitude and awareness of tobacco, exposure to SHS, peer smoking and the situation of tobacco control in schools. Prevention and intervention should be carried out from multi-dimensions to effectively protect teenagers from tobacco hazards.

Objective:
To analyze the epidemiological characteristics of coronavirus disease 2019 ( COVID-19 ) clusters in Lishui, so as to provide basis for the prevention and control of COVID-19 clusters.
Methods:
The data of COVID-19 clusters in Lishui from January 23 to March 29, 2020 were collected through China Disease Control and Prevention Information System-Public Health Emergency Information System, and analyzed time, space, scale, source of infection, exposure and transmission route by descriptive epidemiological method.
Results:
There were 31 cases in 8 clusters ( about 4 cases per cluster ), with no death. The report time was bimodal, peaked first from January 20 to February 10 with 4 clusters imported from domestic and peaked second from March 1 to 29 with 4 clusters imported from overseas. Qingtian County reported 4 clusters, Liandu District, Yunhe County, Qingyuan County and Jingning County each reported 1 cluster. Thirteen cases were restaurant employees, accounting for 41.94%. The cases were mainly occurred in the condition that exposed in the same family ( 6 clusters ), in the same dinner and car ( 1 clusters ), and in the same party ( 1 clusters ). The exposure modes that caused more cases infected were through the same family (9 cases) and through the same dinner and car ( 6 cases ). There were 3 clusters with first-generation cases, 3 clusters with second-generation cases and 2 clusters with third-generation cases. The recurrence rate of the 8 clusters ranged from 1.49% to 7.69%, with a median of 3.47%.
Conclusions
The COVID-19 clusters in Lishui imported from domestic in the early stage and later from overseas. Most cases were reported from Qingtian County, were engaged in catering business, and exposed by living with families.

【Objective】 To investigate the efficacy of neoadjuvant chemotherapy for ovarian cancer and explore the feasibility of hydrogel embedded histoculture drug sensitivity test(HDST) use in selecting chemotherapy regiments for ovarian cancer. 【Methods】 We performed a retrospective analysis of 11 patients with advanced ovarian cancer treated with neoadjuvant chemotherapy as recommended by NCCN guidelines at the department of gynaecological oncology in Sun Yatsen Memorial Hospital. Demographics, clinical data and tissue specimens were collected from patient charts. The patients were grouped according to the HDST results. We compared the differences between groups in the total decline rate of CA125, HE4 and Fagotti scores and analyzed their relationship with HDST results. 【Results】 HDST results showed that 6 patients were not sensitive to the selected platinum drugs(cisplatin or carboplatin) and 1 patient not sensitive to paclitaxel. After 3 times of neoadjuvant chemotherapy, the patients presented a significantly successive decrease in the levels of tumor markers. HDST results were consistent with the clinical efficacy(Kappa=1.000, P<0.05), with 100% sensitivity, 100% specificity and 100% Youden's index. There was a significant positive correlation between changes in Fagotti' sscores and effective rate of HDST(r

Objective: To investigate the impact of type 2 diabetes mellitus on progression and revascularization of coronary non-target lesions in patients with coronary heart disease. Methods: From January 2010 to September 2014, we retrospectively analyzed the clinical data of patients with coronary heart disease who underwent two consecutive coronary angiographies at Fuwai Hospital. At least one coronary non-target lesion was recorded at the first procedure in these patients. Patients were grouped according to the diagnose of type 2 diabetes mellitus. Demographic features, risk factors of coronary heart disease, laboratory results as well as characteristics of coronary non-target lesions were collected at baseline (first coronary angiography) and follow-up (second coronary angiography). Lesion progression was defined by quantitative coronary angiography analysis. Lesions revascularization was recorded. Multivariable Cox regression analysis was used to define the impacts of diabetes mellitus on progression and revascularization of non-target lesions. Subgroup analysis in diabetic and non-diabetic groups were further performed. Receiver operating characteristics curve was used to identify the predictive value of HbA1c. Results: A total of 1 255 patients were included, and 1 003(79.9%) were male, age was(58.0±9.7) years old. And 486 patients were diagnosed with type 2 diabetes mellitus. Follow-up time was (14.8±4.5) months. Compared with non-diabetic group, diabetic group were older with less male and had higher BMI index as well as higher prevalence of hypertension, dyslipidemia, prior myocardial infarction and prior percutaneous coronary intervention(all P<0.05). Diabetic patients also had higher level of white blood cells, erythrocyte sedimentation rate, C-reactive protein, endothelin and HbA1c at both baseline and follow-up compared with non-diabetic patients (all P<0.01). There was no significant difference on progression of non-target lesions (20.0%(97/486) vs. 18.5%(142/769), P=0.512), revascularization of non-target lesions (13.2%(64/486) vs. 15.9%(122/769), P=0.190) and non-target lesion related myocardial infarction(1.9%(9/486) vs. 1.3%(10/769), P=0.436) between diabetic and non-diabetic patients. Multivariable Cox regression analysis revealed that diabetes mellitus was not an independent predictor for progression and revascularization of non-target lesions (Both P>0.05). Subgroup analysis in diabetic patients showed that baseline HbA1c level(HR=1.160, 95%CI 1.009-1.333, P=0.037) was an independent predictor for non-target lesion progression. Cut-off value of HbA1c was 6.5% (Area Under Curve(AUC) 0.57, specificity 88.7%; sensitivity 24.2%, P=0.046) by receiver operating characteristics curve. Patients with HbA1c level above 6.5% had 2.8 times higher risk of lesion progression compared with patients with HbA1c level below 6.5% (HR=2.838, 95%CI 1.505-5.349, P=0.001). Compared with non-diabetic patients, diabetic patients with HbA1c below 6.5% also had lower risk of lesion progression (HR=0.469, 95%CI 0.252-0.872, P=0.012). ST-segment elevated myocardial infarction was an independent predictor for revascularization of non-target lesions in diabetic patients. Conclusion: Type 2 diabetes mellitus is not an independent predictor for progression and revascularization of coronary non-target lesions in patients with coronary heart disease. However, elevated HbA1c level is a risk factor for progression of non-target lesion in patients with type 2 diabetes mellitus.

BACKGROUND:
Coronary atherosclerotic plaque could go through rapid progression and induce adverse cardiac events. This study aimed to evaluate the impacts of smoking status on clinical outcomes of coronary non-target lesions.
METHODS:
Consecutive patients with coronary heart disease who underwent two serial coronary angiographies were included. All coronary non-target lesions were recorded at first coronary angiography and analyzed using quantitative coronary angiography at both procedures. Patients were grouped into non-smokers, quitters, and smokers according to their smoking status. Clinical outcomes including rapid lesion progression, lesion re-vascularization, and myocardial infarction were recorded at second coronary angiography. Multivariable Cox regression analysis was used to investigate the association between smoking status and clinical outcomes.
RESULTS:
A total of 1255 patients and 1670 lesions were included. Smokers were younger and more likely to be male compared with non-smokers. Increase in percent diameter stenosis was significantly lower (2.7 [0.6, 7.1] % vs. 3.5 [0.9, 8.9]%) and 3.4 [1.1, 7.7]%, P = 0.020) in quitters than those in smokers and non-smokers. Quitters tended to have a decreased incidence of rapid lesions progression (15.8% [76/482] vs. 21.6% [74/342] and 20.6% [89/431], P = 0.062), lesion re-vascularization (13.1% [63/482] vs. 15.5% [53/432] and 15.5% [67/431], P = 0.448), lesion-related myocardial infarction (0.8% [4/482] vs. 2.6% [9/342] and 1.4% [6/431], P = 0.110) and all-cause myocardial infarction (1.9% [9/482] vs. 4.1% [14/342] and 2.3% [10/431], P = 0.128) compared with smokers and non-smokers. In multivariable analysis, smoking status was not an independent predictor for rapid lesion progression, lesion re-vascularization, and lesion-related myocardial infarction except that a higher risk of all-cause myocardial infarction was observed in smokers than non-smokers (hazards ratio: 3.00, 95% confidence interval: 1.04-8.62, P = 0.042).
CONCLUSION
Smoking cessation mitigates the increase in percent diameter stenosis of coronary non-target lesions, meanwhile, smokers are associated with increased risk for all-cause myocardial infarction compared with non-smokers.

Objective: To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) . Methods: The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored. Results: ①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ(2)=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ(2)=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ(2)=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ(2)=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) . Conclusions: HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.

Asian Journal of Andrology 2019;21(2):109-114
Anti-Müllerian hormone (AMH) is a functional marker of fetal Sertoli cells. The germ cell number in adults depends on the number of Sertoli cells produced during perinatal development. Recently, AMH has received increasing attention in research of disorders related to male fertility. This paper reviews and summarizes the articles on the regulation of AMH in males and the serum levels of AMH in male fertility-related disorders. We have determined that follicle-stimulating hormone (FSH) promotes AMH transcription in the absence of androgen signaling. Testosterone inhibits the transcriptional activation of AMH. The undetectable levels of serum AMH and testosterone levels indicate a lack of functional testicular tissue, for example, that in patients with anorchia or severe Klinefelter syndrome suffering from impaired spermatogenesis. The normal serum testosterone level and undetectable AMH are highly suggestive of persistent Müllerian duct syndrome (PMDS), combined with clinical manifestations. The levels of both AMH and testosterone are always subnormal in patients with mixed disorders of sex development (DSD). Mixed DSD is an early-onset complete type of disorder with fetal hypogonadism resulting from the dysfunction of both Leydig and Sertoli cells. Serum AMH levels are varying in patients with male fertility-related disorders, including pubertal delay, severe congenital hypogonadotropic hypogonadism, nonobstructive azoospermia, Klinefelter syndrome, varicocele, McCune-Albright syndrome, and male senescence.

BACKGROUND:
Pulmonary vein (PV) occlusion generally depends on repetitive contrast agent injection when cryoballoon ablation for atrial fibrillation (AF). The present study was to compare the effect of cryoballoon ablation for AF guided by transesophageal echocardiography (TEE) vs. contrast agent injection.
METHODS:
Eighty patients with paroxysmal AF (PAF) were enrolled in the study. About 40 patients underwent cryoballoon ablation without TEE (non-TEE group) and the other 40 underwent cryoballoon ablation with TEE for PV occlusion (TEE group). In the TEE group during the procedure, PVs were displayed in 3-dimensional images to guide the balloon to achieve PV occlusion. The patients were followed up at regularly scheduled visits every 2 months.
RESULTS:
No differences were identified between the groups in regard to the procedure time and cryoablation time for each PV. The fluoroscopy time (6.7 ± 4.2 min vs. 17.9 ± 5.9 min, P < 0.05) and the amount of contrast agent (3.0 ± 5.1 mL vs.18.1 ± 3.4 mL, P < 0.05) in the TEE group were both less than the non-TEE group. At a mean of 13.0 ± 3.3 mon follow-up, success rates were similar between the TEE group and non-TEE group (77.5% vs. 80.0%, P = 0.88).
CONCLUSIONS
Cryoballoon ablation with TEE for occlusion of the PV is both safe and effective. Less fluoroscopy time and a lower contrast agent load can be achieved with the help of TEE for PV occlusion during procedure.

To evaluate the bone strength and structure of patients with obstructive sleep apnea(OSA)by the high-resolution peripheral quantitative computed tomography(HR-pQCT)and to explore the relationship between OSA and osteoporosis. Male patients who visited the Sleep Respiratory Center of our hospital from August 2017 to January 2019 were consecutively recruited.Clinical data including the results of Epworth sleep scale(ESS)scoring and overnight polysomnography were collected.HR-pQCT was used to compare the differences in bone geometry,density,and microstructure between OSA patients and non-OSA people;also,the radius and tibia on the non-dominant side were measured to explore the relationship between OSA and osteoporosis. A total of 83 subjects were enrolled in the study.The number of patients in the mild,moderate,and severe OSA groups and non-OSA group were 21,18,34,and 10,respectively.There was no significant difference in age,blood pressure,ESS score,sleep stage,and sleep efficiency among these four groups(>0.05).Body mass index(BMI)and neck circumference were significantly different among these groups(=4.234,=0.008;=3.100,=0.031).There was no significant difference in the radius indicators(>0.05).For tibia,there were significant differences among the four groups in the cortical area(Ct.Ar)(=3.937,=0.011).There were also significant differences in the bone microstructural indicators including trabecular thickness(Tb.Th)and cortical thickness(Ct.Th)(=6.247,=0.001;=3.746,=0.014),which were significantly lower in the three OSA groups than in the control group.Pairwise comparisons showed that the Ct.Ar in the severe OSA group was significantly higher than that in the mild OSA group(=0.019)and Tb.Th in the control group was significantly higher than those in the mild and moderate OSA groups(=0.006,=0.001).Correlation analysis showed that,within a certain range,total volumetric bone mineral density(Tt.vBMD)and Tb.Th of radius and tibia were negatively correlated with age(=-0.312,=0.004;=-0.328,=0.002;=-0.265,=0.015;=-0.280,=0.010)and positively correlated with BMI(=0.240,=0.029;=0.369,=0.004;=0.299,=0.006;=0.416,=0.010).Stepwise multiple regression analysis showed that Tb.Th of radius and tibia were mostly correlated with BMI(=0.262,=0.008,=0.243,=6.270,=0.000;=0.494,=0.000,=0.186,=7.243,=0.000)and age(=-0.216,=0.030,=0.243,=6.270,=0.000;=-0.306,=0.003,=0.186,=7.243,=0.000).Tt.vBMD of radius had a certain correlation with sleep efficiency and with the decreasing nocturnal mean oxygen saturation caused by OSA(=0.312,=0.002, =-0.249,=0.012,=0.327,=7.482,=0.000). In non-elderly male populations,OSA mainly causes a decrease in Tb.Th and Ct.Th of the tibia.The changes in bone strength and structure are mainly related with age and body size and also have certain correlations with sleep efficiency and with the decreasing nocturnal mean oxygen saturation caused by OSA.
