Objective To investigate the role of RhoA /Rho-kinase pathway in rat models of left heart disease-as-sociated pulmonary hypertension ( PH-LHD) .Methods Twenty male SD rats (3-4 week-old, 90-100 g) were randomly divided into two groups (10 rats in each group):the group C ( control group) with sham operation, and group H ( pulmo-nary arterial hypertension) .The rat model of left heart disease-associated pulmonary hypertension was established by supra-coronary aortic banding in the group H, and the sham surgery was applied for the rats in the group C ( The titanium clip was fixed at the mediastinal tissue adjacent to the artery rather than the ascending aorta).On day 60 after the operation, the cardiac functions, including right ventricular systolic pressure and pulmonary artery pressure were evaluated.After that, all rats were sacrificed and treated with cardiopulmonary lavage in vivo until the lung became white.Then the left lung tissues were fixed in 4%paraformaldehyde for pathological observation while the right lung tissues were frozen for mRNA detec-tion.Results Compared with the group C, both ventricular systolic pressure and pulmonary artery pressure in the group H were increased significantly (P<0.01).Pathological data demonstrated that the pulmonary artery walls in H group were much thicker than that in the group C.Moreover, vascular wall hypertrophy index in the group H was increased greatly compared with that in the group C (P<0.01).QPCR data showed that mRNA levels of Rho kinase, RhoA and ET-A R in the group H were up-regulated compared with the group C ( P<0.01) .Conclusions Rat model of left heart disease-asso-ciated pulmonary arterial hypertension can be successfully established by supracoronary aortic banding.Rho-kinase-media-ted pathway may contribute to the pathogenesis and progress of left heart disease-associated pulmonary arterial hypertension.

Objective: To analyze the epidemiological characteristics of notifiable infectious diseases reported in Zhejiang Province in 2020 for prevention and control. Methods: Data of notifiable infectious diseases reported in Zhejiang Province in 2020 were extracted from China Information System for Disease Control and Prevention. The incidence and death of notifiable infectious diseases were analyzed and compared with the averages from 2015 to 2019; then the characteristics of some key diseases such as coronavirus disease 2019 ( COVID-19 ), influenza and other infectious diarrhea were summarized. Results: Totally 487 271 cases of 30 kinds of infectious diseases were reported. The incidence and mortality rate was 832.94/100 000 and 0.615 4/100 000, which were 7.05% and 14.60% lower than the average value of 2015-2019.The weekly morbidity of Class A and Class B infectious diseases fluctuated between 1.24/100 000 and 3.68/100 000, and hit the bottom in the sixth to eighth week. The morbidity of Class C infectious diseases was 154.19/100 000 in the first week, then dropped to 4.83/100 000 in the second to sixth week and maintained at a low level. High morbidity of infectious diseases were reported in Hangzhou ( 1 412.62/100 000 ), Jinhua ( 960.35/100 000 ) and Ningbo ( 921.25/100 000 ). The morbidity of class C infectious diseases in Hangzhou was 1 248.80/100 000, which was far higher than that of other ten prefecture-level cities. The diseases with high reported morbidity were influenza (438.45/100 000), other infectious diarrhea (140.29/100 000 ), hand-foot-and-mouth disease ( 99.64/100 000 ), pulmonary tuberculosis ( 41.92/100 000 ), syphilis (41.37/100 000) and viral hepatitis ( 30.48/100 000 ). More deaths were reported in AIDS and pulmonary tuberculosis, and the mortality were 0.482 1/100 000 and 0.116 2/100 000. A total of 1 306 confirmed cases, 302 asymptomatic infections and 1 death of COVID-19 were reported. Conclusion In 2020, the incidence rate of notifiable infectious diseases in Zhejiang decreased compared with the average value of 2015-2019. Pulmonary tuberculosis, syphilis and hepatitis B still have high morbidity, and the COVID-19 epidemic spread widely. The morbidity of some respiratory infectious diseases and imported infectious diseases have dropped significantly compared with previous years.

· AIM: To explore the effects of C3F8 tamponade on hypotony on or after primary operation and the prognosis of severe ocular trauma.· METHODS: Twenty-six cases (26 eyes) of severe ocular trauma were treated with pure C3F8 tamponade on or after primary operation. IOP was observed, and the curative effect of C3F8 tamponade was observed on secondary operation with prognosis evaluated.· RESULTS: Hypotony improved in 23 eyes postoperatively,in which 18 eyes with edematous and cloudy cornea, 15 eyes had clear cornea after gas tamponade. Retina was reattached under the gas action in 21 eyes during the secondary operation. Visual acuity improved in 22 eyes, remained unchanged in 3 eyes and decreased in 1 eye during the follow-up of 3-12months.· CONCLUSION: Application of pure C3F8 tamponade on or after primary operation can effectively improve hypotony after severe ocular trauma and benefit a better prognosis.

Objective To explore the change of glyoxalase I in type 2 diabetic ocular muscles palsy (DOMP) and its associations with advanced oxidation protein products (AOPP) and oxidative stress. Methods 58 DOMP patients, 50 T2DM and 30 normal controls were enrolled in this study. Levels of blood lipids, fasting blood glucose, hemoglobin A1c, insulin, serum glyoxalase I, AOPP, malondialdehyde (MDA), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) were measured. Homeostasis model assessment was performed to evaluate the status of insulin resistance (IR). Results Levels of high-density lipoprotein cholesterol, SOD and T-AOC were positively correlated with glyoxalase I and inversely associated to AOPP. Levels of triglycerides , low-density lipoprotein cholesterol , fasting blood glucose , hemoglobin A1c , IR and MDA were negatively correlated with glyoxalase I and positively related to AOPP. AOPP had an inverse association with glyoxalase I (r = -0.823, P < 0.001). Multivariate regression analysis showed that serum levels of glyoxalase I (Sβ = 0.554) and AOPP (Sβ= -0.469) were influencing factors of groups. Conclusion Serum glyoxalase I levels were significantly decreased in DOMP and correlated with AOPP and levels of oxidative stress , which suggest that glyoxalase I could play crucial roles on the development of DOMP.

OBJECTIVETo determine the exact location of the opening of the ejaculatory duct in men and provide some basic anatomical evidence for seminal vesiculoscopy and the treatment of ejaculatory duct obstruction.

METHODSWe performed ureterocystoscopy for 21 male patients aged 26 - 47 years with hematuria (n = 12), hematospermia (n = 2), glandular cystitis (n = 6), and anejaculation after radical resection of rectal carcinoma (n = 1), and meanwhile, with the consent of the patients, massaged the prostate and ejaculatory duct and observed the outlet of the expelled fluid. Under the microscope, we described the fluid samples with sperm as the expulsion from the ejaculatory duct.

RESULTSUreterocystoscopy showed that the exact anatomical sites of the expulsion of prostatic fluid and semen in the patients were the side and lower side of the prostatic utricle opening above the verumontanum and the ventral side of the verumontanum. Quantities of sperm were found in the expulsion fluid of 13 of the patients, and no expulsion, including semen, was seen from the prostatic utricle opening.

CONCLUSIONAnatomically, the ejaculatory duct openings of males are located at the two sides of the verumontanum adjacent to the opening of the prostatic utricle, rather than in the prostatic utricle above the verumontanum.

Objective To investigate the effects of advanced oxidation protein products (AOPP) in type 2 diabetic ocular muscles palsy (DOMP). Methods 58 DOMP patients and 50 type 2 diabetes patients were included in the research. Hemoglobin A1c (HbA1c), blood glucose (FPG), fasting insulin (FINS) and triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) were measured and recorded. Homeostasis model assessment was performed to evaluate the status of insulin resistance (HOMA-IR), basal insulin secretion (HOMA-β) and the insulin sensitivity index (ISI). Serum AOPP was measured by enzyme linked immunosorbent assay. Unconditional logistic regression model was used to evaluate the influencing factors of DOMP. Results The DOMP group showed higher levels of plasma AOPP, TG, LDL, FPG, FINS, HbA1c and HOMA-IR, but lower levels of HDL, HOMA-β and ISI than those of the T2DM group. Unconditional logistic regression analysis revealed that AOPP was an independent risk factors for DOMP (OR =3.01, P = 0.002). Conclusion AOPP may be involved in the pathogenesis of DOMP. AOPP could be a useful indicator for monitoring the development of DOMP and for evaluating its severity.
