Abstract
Objective: To study the effect of diurnal temperature range on the number of elderly inpatients with ischemic stroke in Hunan Province. Method: Demographic and disease data, meteorological data, air quality data, population, economic and health resource data of elderly inpatients with ischemic stroke were collected in 122 districts/counties of Hunan Province from January to December 2019. The relationships between the diurnal temperature range and the number of elderly inpatients with ischemic stroke were analyzed by using the distributed lag non-linear model, including the cumulative lag effect of the diurnal temperature range in different seasons, extremely high diurnal temperature range and extremely low diurnal temperature range. Results: In 2019, 152 875 person-times were admitted to the hospital for ischemic stroke in the elderly in Hunan Province. There was a non-linear relationship between the diurnal temperature range and the number of elderly patients with ischemic stroke, with different lag periods. In spring and winter, with the decrease in diurnal temperature range, the risk of admission of elderly patients with ischemic stroke increased (Ptrend<0.001, Ptrend=0.002);in summer, with the increase in diurnal temperature range, the risk of admission of elderly patients with ischemic stroke increased (Ptrend=0.024);in autumn, the change in the diurnal temperature range would not cause a change in admission risk (Ptrend=0.089). Except that the lag effect of the extremely low diurnal temperature range in autumn was not obvious, the lag effect occurred in other seasons under extremely low and extremely high diurnal temperature ranges. Conclusion: The high diurnal temperature range in summer and the low diurnal temperature range in spring and winter will increase the risk of admission of elderly patients with ischemic stroke, and the risk of admission of elderly patients with ischemic stroke will lag under the extremely low and extremely high diurnal temperature ranges in the above three seasons.

Abstract
Objective: To explore the risk factors of pneumoconiosis patients' re-admission to provide a scientific basis for improving the treatment effect of pneumoconiosis, reducing the rate of re-admission, and reducing the burden of disease. Methods: In June 2020, The clinical data of 470 patients with pneumoconiosis who had hospitalization records from February 8, 2014, to February 8, 2020, in the Hunan Provincial Occupational Disease Prevention and Treatment Institute were retrospectively analyzed. The patients' general data and emotional state at the first admission were collected through questionnaires and telephone follow-ups. The entire group of patients completed at least one follow-up, with readmission as the end event. First, the Kaplan-Meier method was used for univariate analysis. The multivariate COX regression model analysis was performed on meaningful variables to explore the risk factors that affect the patient's re-admission. Results: A total of 470 patients with pneumoconiosis were included in this study, with an average age of 55.88 years (34-81 years old) and all the participants were male. During the first admission, the number of participants diagnosed as stage III pneumoconiosis, with complications of COPD, fatty liver, or severe pulmonary diffusion dysfunction was 215 (45.74%) , 179 (38.09%) , 51 (10.85%) , and 44 (9.36%) , respectively. Six patients (1.28%) have had suicidal tendencies almost every day since they became ill. A total of 345 patients (73.40%) were re-admitted to the hospital. Multivariate Cox regression model analysis showed that compared with the suspected pneumoconiosis group, patients in the first, second, and third-stage pneumoconiosis groups had an increased risk of readmission (OR=2.43, 2.96, 2.35, P=0.000) . Compared with the age of 30-50 years old, 50-70 years old and ≥70 years old have an increased risk of readmission (OR=1.28, 2.32, P<0.05) . Patients with tricuspid regurgitation (OR=1.33, P<0.05) and elevated triglyceride level (>2.26 mmol/L) (OR=1.40, P<0.05) have increased risks of readmission. Compared with the normal group, patients with severe pulmonary diffusion dysfunction in pneumoconiosis have an increased risk of readmission (OR=1.96, P<0.05) . Compared with the normal group, pneumoconiosis patients in the suicidal group had an increased risk of re-admission to the hospital almost every day (OR=2.92, P<0.05) . Conclusion Age of onset, stage of pneumoconiosis, tricuspid regurgitation, high triglycerides, severe diffuse pulmonary dysfunction, and suicidal tendency are independent risk factors that affect the readmission of patients with pneumoconiosis. The management of chronic diseases and mental health of patients with pneumoconiosis should be strengthened to reduce the risk of readmission. Conclusion: Age of onset, stage of pneumoconiosis, tricuspid regurgitation, high triglycerides, severe diffuse pulmonary dysfunction, and suicidal tendency are independent risk factors that affect the readmission of patients with pneumoconiosis. The management of chronic diseases and the mental health of patients with pneumoconiosis should be strengthened to reduce the risk of readmission.

Abstract
Objective: To analyze the epidemiological characteristics of newly reported HIV-infected cases aged 50 years and above in Henan province during 1995-2020, and to provide evidence for strategies on HIV/AIDS prevention and control. Methods: Information about newly reported HIV-infected cases aged 50 years and above in Henan between 1995 and 2020 were collected from the National Comprehensive HIV/AIDS Information System. The demographic and behavioral characteristics of HIV-infected cases aged ≥50 were analyzed, and the mixed linear model based on CD4+ T lymphocyte (CD4) counts back calculation was used to estimate the years, time and age of the HIV infection. Results: During 1995-2020, a total of 25 038 HIV-infected cases aged 50 years and above were newly reported, accounting for 25.8% (25 038/96 867) of the total number of newly reported HIV-infected cases in Henan. The proportion of newly reported cases over 50-years-old gradually increased from 4.5% (18/396) in 1995-2000 to 35.5% (9 666/27 239) in 2016-2020, with statistically significant difference (χ2=3 105.53, P<0.001). Among them, the proportion of HIV-infected cases aged 60 years and above were increasing year by year. The proportion of male cases were increasing along with ageing. The proportion of HIV-infected cases detected by medical institutions also showed an upward trend. The newly reported HIV-infected cases aged 50 years and above were mainly transmitted through sexual contact. The proportion of heterosexual transmission increased from 5.5% (1/18) in 1995-2000 to 86.2% (8 334/9 666) in 2016-2020, and the proportion of MSM-behavior-related transmission increased from 0.0% in 1995-2000 to 13.5% (1 304/9 666) in 2016-2020. The majority of cases had extra-marital and/or non-commercial heterosexual behavior (48.1%, 4 007/8 334) and the proportion showed an upward trend. The majority of male cases had commercial heterosexual behavior (54.9%, 3 169/5 775), and with increasing proportion along with the increase of age. The majority of female cases had extra-marital and/or non-commercial heterosexual behavior (62.5%, 1 600/2 559), with increasing proportion of extra-marital and/or non-commercial heterosexual behavior. The proportion of heterosexual behavior with spouse or stable sexual partners showed a downward trend. The estimations based on CD4 counts back calculation model showed that among the newly reported HIV-infected cases aged 50 years and above, the average age being infected was (54.8±10.2) years, with 33.8% (4 263/12 621) infected before 50. The interval between infection and diagnosis was (5.7±6.2) years, of which 52.6% (6 636/12 621) were infected for 5 years or longer and 34.7% (4 384/12 621) were in the last 3 years. There was no linear correlation trend in the composition of infection years among the newly reported HIV-infected cases over 50-years-old. Conclusions: In Henan, from 1995 to 2020, the number of newly reported HIV-infected cases aged 50 years and above was increasing and sexual transmission becoming the main transmission route. The increase of prevalence was mostly seen in 60-years-old men, low education level and detected mainly by medical institutions. For this age group, the focus of HIV/AIDS prevention and control should target on those who were transmitted through extra-marital and/or non-commercial heterosexual, commercial heterosexual and MSM behavior and it is necessary to strengthen the HIV testing and detection in this population and in the elderly floating group.

Abstract
Background The anatomy of the right posterior portal vein (RPPV) plays an important role in planning hepatic resection, living transplantation and interventional radiological procedures, yet the incidence of variations of RPPV without a common trunk in Chinese persons is still unclear. Therefore, we conducted this study and discussed its clinical implications. Methods A retrospective analysis of multidetector computed tomography (MDCT) scans was performed in 1,933 patients with various abdominal pathologies between September 28, 2018 through May 23, 2019. After excluding 930 patients, a total of 1,003 patients were included in this study. Variations of the RPPV without a common trunk were classified according to classification standards. Results A total of 1,003 patients were included. RPPV without a common trunk was found in 216 (21.54%, 216/1,003) patients. Among them, we identified three variations of the origin from the right portal vein (RPV): first separate origin of P6, P7, or simultaneous separate origin of P6 and P7, and the incidences of these three variations were 1.50% (15/1,003), 6.58% (66/1,003) and 13.46% (135/1,003), respectively. Among 1,003 patients included in this study, 787 patients (78.46%, 787/1,003) showed that RPPV normally divided into P6 and P7 branches. Conclusions Variations of the RPPV without a common trunk were not rare in Chinese population. Knowledge of this anatomic variation of the RPPV is extremely important for hepatic and transplant surgeons and interventional radiologists.

Abstract
Background The colposcopy-conization inconsistency is common in women with cervical intraepithelial neoplasia grade 3 (CIN3). No adequate method has been reported to identify the final pathology of conization. In this study, we explored the ability of PAX1 and ZNF582 methylation to predict the pathological outcome of conization in advance. Methods This was a multicenter study and included 277 histologically confirmed CIN3 women who underwent cold knife conization (CKC) from January 2019 to December 2020. The methylation levels of PAX1 (PAX1m) and ZNF582 (ZNF582m) were determined by quantitative methylation-specific polymerase chain reaction (qMSP) and expressed in ΔCp. Receiver operating characteristic curves were used to evaluate predictive accuracy. Results The final pathological results in 48 (17.33%) patients were inflammation or low-grade squamous intraepithelial lesion (LSIL), 190 (68.59%) were high-grade squamous intraepithelial lesion (HSIL), and 39 (14.08%) were squamous cervical cancer (SCC). PAX1m and ZNF582m increased as lesions progressed from inflammation/LSIL, HSIL, to SCC. PAX1 and ZNF582 methylation yielded better prediction performance compared with common screening strategies, whether individually or combined. A 4.33-fold increase in the probability of inflammation/LSIL was observed in patients with lower ZNF582 methylation levels (ΔCpZNF582 ≥ 19.18). A 6.53-fold increase in SCC risk was observed in patients with elevated ZNF582 methylation (ΔCpZNF582 < 7.09). Conclusions DNA methylation would be an alternative screening method to triage and predict the final outcome of conization in CIN3 cases.

Abstract
PURPOSE The optimal treatment for isolated abdominal aortic dissection (IAAD) is currently unknown. We compared the effects of straight and bifurcated aortic stent grafts on postoperative aortic remodeling in patients with IAAD. MATERIALS AND METHODS From February 2012 to December 2019, 57 patients with IAAD were treated using endovascular methods, including either a bifurcated or a straight aortic stent graft. The clinical features, risk factors, computed tomography angiograms, midterm follow-up results, and aortic remodeling of these patients were reviewed and analyzed. RESULTS In total, 44 (77%) patients were treated with a bifurcated graft and 13 (23%) patients were treated with a straight graft. Patients treated with straight grafts had fewer common iliac arteries involved (38% vs 73%, p=0.023), the dissection length was shorter (76.3 ± 40.0 vs 116.2 ± 56.7 mm, p=0.011), and the preoperative aortic diameter (26.0 ± 5.6 vs 35.2 ± 12.1 mm) and the false lumen diameter (13.1 ± 5.2 vs 21.2 ± 11.3 mm) were smaller. During the procedure, there were 3 (5.3%) type I endoleaks, 1 (1.8%) surgical conversion and 1 (1.8%) partial renal artery coverage without perioperative mortality. Patients with straight grafts had shorter operative time (96.5 ± 24.4 vs 144.2 ± 49.0 minutes, p<0.0001). The median follow-up duration was 37.6 ± 21.0 (range = 3-89) months with 1 (1.8%) aortic-related death. Type A aortic dissection occurred in 1 (1.8%) patient. New descending aortic dissection occurred in 3 (5.3%) patients, and 1 patient advanced to type A aortic dissection 3 months later. Two (3.5%) patients had limb occlusion. There was no significant difference in aortic remodeling, survival, and freedom from all adverse events between the 2 treatment strategies. CONCLUSIONS Endovascular treatment provides a safe, minimally invasive treatment for IAAD in midterm follow-up. Compression of the true lumen at the aortic bifurcation is the main concern after treatment with a bifurcated graft. Straight grafts are an excellent alternative for some patients, with the benefit of reduced procedural time, effective aortic remodeling, and excellent clinical prognosis. More experience is needed to offer clear recommendations for making treatment decisions as well as determine long-term effectiveness and durability.

Abstract
OBJECTIVE To explore treatment strategies for patients with positive margins after cervical cold knife conization (CKC) by estimating the risk of residual or recurrent CIN2 or worse (CIN2+). METHODS A retrospective study included 569 patients receiving CKC for CIN3 in Xiangya Hospital from January 2013 to December 2017. Demographic characteristics and test results were obtained before CKC, after CKC, at 6, 12, and 24 months, then annually thereafter. The primary end point was residual/recurrent CIN2+ post-CKC. RESULTS Fourteen (2.46%) patients had residual/recurrent CIN2+ with a median time of occurrence at 12 months post-CKC. Taking the average age and hrHPV viral load tested by Hybrid Capture 2 (HC2) as thresholds, the risk of residual/recurrent CIN2+ was higher in women aged over 40 years or with a baseline HC2 of 300 or more for the ratio of relative light units to positive cut-off values. Patients with positive margins were at higher risk of residual/recurrent CIN2+ (hazard ratio 3.66, 95% confidence interval 1.25-10.71), especially when endocervix was involved. A total of 536 (94.20%) patients received HPV testing within 6 months after CKC. Patients with both positive HPV testing results and positive margins were at the highest risk of residual/recurrent CIN2+. CONCLUSION Patients with positive endocervical margins are at high risk for residual/recurrent CIN2+, independent of the severity of margins. HPV testing within 6 months after CKC may be a feasible triage strategy for these patients.

Abstract
Four C2H4N4 structural isomers are investigated with fs laser-induced breakdown spectroscopy. Plasma emissions, C I, Hα, the CN violet system (B2Σ+-X2Σ+, Δν = 0 sequence) and C2 swan system (d3Πg-a3Πu, Δν = 0 sequence) are measured. The temporal evolution of the characteristic emission intensity is obtained for each emission and their lifetimes are calculated. The lifetimes of the molecular emissions are much longer than those of the atomic emissions. Characteristic emission intensities and lifetime are correlated with the molecular structures of the four isomers to a certain extent. Plasma temperature is extracted by fitting the spectrum of the CN violet system, B2Σ+-X2Σ+; Δν = 0 sequence, and is weakly correlated with the molecular structures of the four isomers. Using the characteristic emission intensities as input, principal component analysis (PCA) and artificial neural network (ANN) analysis are performed and the individual isomers can be well identified with PCA or ANN.

Abstract
We investigate atomic and molecular emission of laser-ablated nitromethane in an Ar or N2 buffer gas, with fs laser-induced breakdown spectroscopy. The electronic bands of CN, C2, and NH molecules and the atomic transition lines of C I, N I, and Hα are identified. The time series of the emissions are obtained, and the formation mechanisms of CN and C2 are deduced. The CN violet system, the B2Σ+-X2Σ+ (0-0) band, is chosen to extract plasma temperature from the experimental spectra.

Abstract
Objective: The serotype screening of Shigella flexneri from 1934 to 1965 preserved by the National Center for Medical Culture Collections was carried out, and the molecular characteristics of the serotype conversion strains were studied. Methods: Serotyping of Shigella flexneri in this study was conducted by slide agglutination and multiplex PCR, respectively. The gtrⅡ gene sequence alignment and pulsed field gel electrophoresis typing were performed on the serotype conversion strains. Results: Among the 255 strains of Shigella flexneri preserved in CMCC (B) from 1934 to 1965, 79 were carrying gtrⅡ gene, of which 19 strains and 1 strain were agglutinated with the Y serotype and X serotype, respectively, and furthermore, the multiplex PCR assays results showed serotypes 2a and 2b, respectively, and the strains were considered to have serotype conversion. The 20 strains carrying the gtrⅡ gene showed multiple nucleotide mutations. Besides 3 strains of 3 amino acid mutations, the amino acid sequences of the other 17 strains showed a stop codon in advance, resulting in functional inactivation of gtrⅡ. PFGE analysis revealed that the similarity between the serotype Y strain carrying the gtrⅡ gene and the serotype 2a strain was 75.8%-100%, and the similarity between the serotype X strain carrying the gtrⅡ gene and the serotype 2b strain was 81.6%-100%. Conclusion: Mutations in the gtrⅡ gene are more complicated in serotype-transforming Shigella flexneri serotype Y or X strains. Molecular typing suggests that the serotype-transforming Shigella flexneri serotype Y or X strains may be derived from the Shigella flexneri serotype 2a or 2b, and advance the serotype conversion to 1949.

Abstract
Hydrogen abstractions by NO2 from symmetric ethers are investigated to determine the rate constants and explore the effect of the functional group on rate constants at different reaction sites. The involved ethers are dimethyl ether (DME), diethyl ether (DEE), dipropyl ether (DPE), and dibutyl ether (DBE). The B3LYP method with a 6-31G(2df,p) basis set is employed to optimize the ground-state geometries and for frequency and intrinsic reaction coordinate calculations. The G4 method is used to calculate the electronic energies for the small ethers (DME and DEE). Given the heavy computational cost of the G4 method, the modified G4MP2 method is applied for larger ethers (DPE and DBE) and also for DME to verify the accuracy of the G4MP2 method by benchmarking with the G4 method. The high-pressure limit rate constants are calculated within the temperature range of 500-2000 K, with the asymmetrical Eckart tunneling correction as well as one-dimensional hindered rotor treatment. The calculated rate constants agree well with the literature data, and the branch ratio analysis suggests that the cis-HONO channel basically dominates the hydrogen abstraction reactions and shows a decrease at high temperatures, followed by HNO2 and trans-HONO channels; in addition, the hydrogen abstraction at the C site adjacent to the ether bond (α reaction site) accounts for most of the reactions. Furthermore, the total rate constants of the ethers are compared to those of their half-structurally alkanes, and linear Bell-Evans-Polanyi correlations are observed.

Abstract
OBJECTIVE To verify the efficacy of abendazole emulsion, a new formulation of abendazole, in treatment of human cystic echinococcosis. METHODS 212 patients with liver cystic echinococcosis were treated orally with albendazole emulsion at a daily dose of 10 mg/kg or 12.5 mg/kg for 3 to 12 months or over one year. The therapeutic efficacy was mainly evaluated by image feature examined with B ultrasound examination, a short-term efficacy at the completion of treatment and a long-term efficacy followed-up for 1-4 years. RESULTS In 212 patients treated with albendazole emulsion at a daily dose of 10 mg/kg and 12.5 mg/kg, the average cure rate, improved rate and the rate of no avail were 74.5%, 99.1% and 0.9% respectively after termination of the treatment, and the average long-term rates were 83.1%, 89.3% and 0.6% respectively. Recurrence occurred in 18 patients(10.2%). The results indicated that the best efficacy was seen in patients treated with albendazole 12.5 mg/kg daily for 9 months. Better response was also found when the recurrent patients were re-treated with albendazole. CONCLUSION The efficacy of albendazole emulsion on patients with liver cystic echinococcosis is much better than that of albendazole tablet or capsule and mebendazole. Meanwhile, the efficacy of albendazole emulsion is stable with less adverse effects. The results suggest that albendazole emulsion could be the drug of choice for treatment of cystic hydatid disease.

Abstract
Male Sprague-Dawley rats, weighing 180-250 g and depleted with water for 16 h, were injected with glycerol (im) to induce acute tubular necrosis, and then divided into groups given blood-activating and stasis-removing drug, Hirudo solution (GH) tap water (GW), verapamil (GV) and none (GSDW) in incipient stage separately. It was observed that levels of BUN increased at 24th and 48th h after administration of glycerol and levels of Bcr increased at 3rd, 24th and 48th h after injecting glycerol in GH were significantly lower than those increased in GW and GSDW (P less than 0.05-P less than 0.001), but roughly similar to those in GV (P greater than 0.05-P greater than 0.5). Renal histopathological damage under light microscope and electron-microscope in GH at 3rd and 24th h after administration of glycerol were also less severe than those in GW and GSDW. The results suggested that Hirudo could exert a preventive and therapeutic effects on incipient acute tubular necrosis induced by glycerol in rats.
