ABSTRACT
Objective:To analyze the source of infection, clinical symptoms and epidemiological characteristics of pertussis surveillance cases in Minhang District of Shanghai from 2017 to 2019,so as to provide the basis for pertussis surveillance and immunization strategy. Methods:Descriptive epidemiological method was used to analyze the pertussis surveillance cases. Results:A total of 334 cases were included in the pertussis active surveillance system, 237 cases were confirmed cases. There were 13 towns or streets in Minhang District, except for Pujin Street, all the other 12 towns or streets had cases. The high risk group (131/237, 55.27% of the cases) were the infants under five months old who did not reach the age of immunization or did not complete the basic immunization of diphtheria, tetanus, and acellular pertussis combined vaccine (DTaP). The cases mainly occurred in March to July, accounting for 71.31% (169/237). The highest culture-positive rate of Bordetella pertussis was in August (82.76%, 24/29); the highest positive rate of polymerase chain reaction (PCR) detection was in March (58.82%, 20/34). All the monitored cases had cough symptoms with an average cough days of 22.05±9.81 in confirmed cases. A total of 64 clustered outbreaks were detected, with an attack rate of 37.45% (94/251). 32.91% (78/237) of the cases had contact history with coughing patients 21 days before the onset, and 94.87% (74/78) of them were family members. The aggregation of pertussis was mainly transmitted from adults to infants and infants to adults. Conclusion:Children under five months old are the high incidence population of pertussis, and family members are the main source of infection. It is suggested that pertussis monitoring and prevention should be carried out in adolescents and adults.
ABSTRACT
The development of Chinese medicine and Western medicine andrology is based on different social background and academic systems, either Chinese medicine or Western medicine andrology has their limitations, therefore, integration of Chinese and Western medicine (ICWM) andrology is in a great need. After more than 30 years of development, andrology has made great achievements in the construction of specialized academic association, holding academic conferences and publication of academic monographs, and the research progress on this field is mainly in the combination of disease and syndrome, microdifferentiation of symptoms and signs and basic research development. However, the comprehensive theoretic system of ICWM andrology has not yet established, and the related studies are still on the primary stage. In the future studies, great efforts still need to be made to expand the methods for the investigation of ICWM, and make innovations in the field of andrology.

Spermatogenesis is a complex and precise process of differentiation of germ cells, which involves three stages: mitosis of spermatogonia, meiosis of spermatocytes and formation of spermatozoa. The process is controlled by many factors, including regulation of cyclins in spermatogenic cells, which plays a pivotal role. Cyclins form heterologous dimer compounds with protein kinase activity by binding to cyclin-dependent kinases, then phosphorylate multiple proteins and promote the orderly conduct of each phase of the cell cycle. In recent years, cyclins A, B, D and E have been found to play important roles in the regulation of spermatogenesis. This article presents an overview on the roles of these four cyclins in regulating the progression of spermatogenesis.

<p><b>OBJECTIVE</b>To investigate the effect of Bushengzhuyang Fang (Yangjing Capsule, YJC) on penile erectile function and its action mechanisms in rats.</p><p><b>METHODS</b>Fifty-six male SD rats were randomly divided into seven groups of equal number: blank control, daidzein, daidzein + testosterone, daidzein + sildenafil, daidzein + low-dose YJC, daidzein + medium-dose YJC, and daidzein + high-dose YJC. The rats in the blank control group were treated intragastrically with normal saline and those in the other groups with daidzein at the dose of 100 mg per kg per day for 30 days. Then the last five groups received additionally testosterone (4 mg per kg per day), sildenafil (2.5 mg per kg per day), low-dose YJC, (0.315 mg per kg per day), medium-dose YJC (0.63 mg per kg per day), and high-dose YJC (1. 26 mg per kg per day), respectively. At 0, 30 and 60 days of treatment, we observed the apomorphine-induced spontaneous erectile response and pathological changes in the corpus cavernosum of the rats, recorded the number of penile erection and erectile incubation period, and determined the serum levels of testosterone (T) and luteinizing hormone (LH).</p><p><b>RESULTS</b>At 30 days of treatment, the number of apomorphine-induced erections was decreased, the erectile incubation period prolonged, and the serum levels of T and LH reduced remarkably in all groups of rats (P < 0.05). Compared with the findings at 30 days, the number of penile erections was significantly decreased at 60 days in the daidzein group (1.39 ± 0.42 vs 2.67 ± 0.33, P < 0.05) and daidzein + low-dose YJC group (1.33 ± 0.49 vs 2.83 ± 0.61, P < 0.05); the erectile incubation period was markedly ex- tended ([16.33 ± 3.11] vs [8.50 ± 0.93] min and [15.50 ± 3.21] vs [8.63 ± 1.54] min, P < 0.05); and the serum levels of T ([5.34 ± 0.89] vs [1.24 ± 0.30] ng/ml and [5.28 ± 1.12] vs [2.07 ± 0.76] ng/ml, P < 0.05) and LH ([3.62 ± 0.37] vs [2.09 ± 0.12] ng/ml and [3.79 ± 0.28] vs [2.17 ± 0.33] ng/ml, P < 0.05) were significantly reduced in the daidzein and daidzein + low-dose YJC groups, respectively. Pathological examination revealed slightly decreased cavernous sinuses and blood vessels in the corpus cavernosum of the rats in the daidzein + testosterone, daidzein + sildenafil, daidzein + medium-dose YJC, and daidzein + high-dose YJC groups as compared with those in the blank control group.</p><p><b>CONCLUSION</b>High-dose Yangjing Capsule is efficacious for the recovery of erectile function in rats, especially for phytoestrogen-induced erectile dysfunction.</p>

<p><b>OBJECTIVE</b>To observe the effects of Yangjing Capsule (YJC) on the ultrastructure of seminal vesicles in aged male rats, and explore its mechanism of improving the secretion of seminal vesicles.</p><p><b>METHODS</b>Fifty male SD rats aged 18 -20 months were randomly and equally divided into a control group, a testosterone undecanoate group, and a high-dose, a medium-dose and a low-dose YJC group, all fed intragastrically for 30 days. Then the seminal vesicles of the rats were removed and the seminal fluid squeezed into the test tube to be weighed and measured for the concentration of seminal vesicle fluid fructose, and the bilateral seminal vesicles were placed in formaldehyde and glutaraldehyde fixatives for histological observation.</p><p><b>RESULTS</b>The seminal vesicle gland viscera coefficient, seminal vesicle fluid weight and fructose concentration of the rats were (1164.5 +/- 212.6) g/g x 10(6), (0.83 +/- 0.30) g and (4.35 +/- 0.31) mg/ml in the control group, (1510.5 +/- 313.1) g/g x 10(6), (0.82 +/- 0.25) g and (5.35 +/- 0.71) mg/ml in the testosterone undecanoate group, (1484.3 +/- 262.7) g/g x 10(6), (1.14 +/- 0.18) g and (5.30 +/- 0.45) mg/ml in the high-dose YJC group, (1396.6 +/- 268.9) g/g x 10(6), (0.83 +/- 0.24) g and (4.71 +/- 0.41) mg/ml in the medium-dose YJC group, and (1475.0 +/- 305.2) g/g x 10(6), (0.74 +/- 0.28) g and (4.50 +/- 0.23) mg/ml in the low-dose YJC group. Compared with the control, high-dose YJC significantly improved seminal vesicle secretion (P < 0.05), while medium- and low-dose only achieved a trend of improvement. After HE staining, the YJC groups showed more active epithelial hyperplasia, increased cellular layers, rich and transparent cytoplasm with abundant secretory granules, fat droplets and lipofuscin, blurred glandular cavity edge, and eosinophilic intraluminal secretions, as compared with the control group. The structural change was most significant in the high-dose group. Statistically significant differences were observed in the numerical density and bulk density of the secretory granules between the YJC and control groups (P < 0.05).</p><p><b>CONCLUSION</b>Yangjing Capsule can improve the secretion of seminal vesicles by increasing the secretory granules of the main</p>

<p><b>OBJECTIVE</b>To observe the effect of Yangjing Capsule on the expressions of P-Erk1 and P-Akt1 in the corpus cavernosum of aged rats and to explore its action mechanism.</p><p><b>METHODS</b>Forty 24-month-old SD rats were equally randomized into an experimental and a control group, 10 selected from each group for detection of the eNOS expression before medication. The rats in the experimental group (n = 10) were treated intragastrically with Yangjing Capsule, while those in the control with physiological saline, both at 0.5 g per kg body weight per day for 4 weeks. Then all the rats were killed, and the corpus cavernosum tissues harvested for determination of the expressions of eNOS, P-Erk1 and P-Akt1 by HE staining, RT-PCR and immunohistochemistry.</p><p><b>RESULTS</b>Obvious distension was observed in the experimental group, but not in the control. The expression of eNOS in the rat corpus cavernosum was significantly higher after treatment than before treatment in the experimental group (24.10 +/- 2.40 vs 18.80 +/- 2.04, P < 0.05), but presented no obvious difference in the control (18.15 +/- 1.98 vs 19.35 +/- 1.50, P > 0.05), and it was remarkably higher in the former than in the latter (P < 0.05). The expression of P-Erk1 was markedly lower in the experimental than in the control rats (0.71 +/- 0.13 vs 0.83 +/- 0.17, P < 0.01), but that of P-Akt1 exhibited no remarkable difference in the same condition of GAPDH between the two groups (0.58 +/- 0.17 vs 0.48 + 0.13, P > 0.01).</p><p><b>CONCLUSION</b>Both P-Erk1 and P-Akt were expressed in the corpus cavernosum of the aged rats. Yangjing Capsule could improve the sexual function of aged rats, which might be associated with the lowered expression of P-Erk1.</p>

<p><b>OBJECTIVE</b>To analyze the adverse events following immunization (AEFI) in Minhang District of Shanghai from 2007 to 2010 and evaluate the safety of vaccines.</p><p><b>METHOD</b>The data of AEFI cases were collected and reported by the Vaccine Adverse Events Surveillance System (VAESS). The data were classified as non-serious or serious reaction according to the symptoms and medical records.</p><p><b>RESULT</b>From 2007 to 2010, 5088 AEFI cases were reported to the surveillance system after 4.85 million doses of 24 kinds of vaccines (viral vaccines, bacterial vaccine and non-vaccine product) use. A total of 5013 non-serious AEFI were reported with a rate of 103.24/100 000 doses. Among the non-serious AEFIs, the majority were fever (3314 cases, 68.25/100 000 doses), followed by local reactions (1686 cases, 34.72/100 000 doses). A total of 75 serious AEFIs were reported, with a rate of 1.54/100 000 doses. The anaphylaxis (26 cases, 0.54/100 000 doses) accounted for the most among the serious AEFIs, followed by allergic rash (24 cases, 0.49/100 000 doses) and abscess at injection site (14 cases, 0.29/100 000 doses). The susceptibility of data on AEFI rose year by year from 2007 to 2010, and the reported rate rose from 40.48/100 000 in 2007 to 134.17/100 000 in 2010.</p><p><b>CONCLUSION</b>To maintain the sensitivity of AEFI surveillance is key to detect rare serious adverse events. The sensitivity should be enhanced, at the same time, pediatricians should treat the AEFI with standard methods, so as to minimize the negative impacts of vaccination and to maintain the confidence among the public.</p>

<p><b>OBJECTIVE</b>To observe the effects of Yixin Kangtai Capsule (YKC) on sperm concentration and motility, superoxide dismutase (SOD) and malondialdehyde (MDA) in aged SD rats, and to explore its possible mechanisms of action.</p><p><b>METHODS</b>We randomly assigned fifty 24-month-old male SD rats to five groups of equal number: blank control, testosterone undecanoate, high-dose YKC, medium-dose YKC and low-dose YKC, and treated them intragastrically with physiological saline at 10 ml/kg, testosterone un-decanoate suspension at 4 mg/kg, and YKC at 0.6 g/kg, 0.3 g/kg and 0.15 g/kg, respectively, once a day for 30 days. Then we harvested the epididymides, which were stripped of fat and envelope, cut into pieces and placed in the saline at 37 degrees C for 10 to 15 minutes. Then we detected the sperm parameters with the Weili CASA sperm analysis system, measured the levels of serum SOD and MDA, and, following HE staining, observed the histomorphological changes of the testicular tissue under the light microscope.</p><p><b>RESULTS</b>Compared with the controls, the rats treated with high-, medium- and low-dose YKC exhibited significantly increased sperm concentration ([152.3 +/- 24.0] x 10(6)/ml vs [334.5 +/- 97.7], [302.7 +/- 158.9] and [221.4 +/- 75.6] x 10(6)/ml, P < 0.05) and markedly improved sperm motility ([26.5 +/- 2.0]% vs [35.5 +/- 5.9], [33.1 +/- 5.4] and [28.4 +/- 2.1]%, P < 0.01). High-dose YKC significantly increased the level of serum SOD ([22.0 +/- 5.3] U/ml, P < 0.01) and reduced the content of MDA ([13.6 +/- 4.6] nmol/ ml, P < 0.01). Testicular histology showed that YKC induced more active proliferation of cells, and increased the number of dividing cells and that of mature sperm in the lumen, with little interstitium, abundant blood vessels, and well-developed stromal cells.</p><p><b>CONCLUSION</b>Yixin Kangtai Capsule can improve spermatogenesis in aged SD rats by regulating the levels of SOD and MDA.</p>

Azoospermia factor (AZF) microdeletions of the Y chromosome, which occur in 1 - 55% of infertile men, are closely associated with severe spermatogenic failure and represent the most frequent molecular genetic causes of azoospermia and severe oligozoospermia. Researches on AZF and its related genes, approaching the mechanisms of spermatogenic failure at the molecular level, are of great significance for the diagnosis, treatment and prognosis of male infertility. The detection of AZF microdeletions can provide scientific basis for correct diagnosis and reasonable therapy. This article outlines the structure and functional characteristics of AZF, as well as its relationship with male infertility, cryptorchidism, varicocele, Klinefelter syndrome, seminoma, and recurrent abortion.
