Chinese Journal of Emergency Medicine 2011;20(9):935-939
ObjectiveTo explore the intervention effect and the underlying molecular mechanism of 3-Methyladenine on behavioral damage of neonatal rat with prolonged seizures. MethodsForty-five 6-dayold SD rats were randomly ( random number) divided into the recurrent prolonged neonatal seizure group ( RS group), the 3-MA-treated seizure group and control group. The volatile agent flurothyl was used to induce 30 min seizure attack. At postnatal day 6 (P6), recurrent seizures were induced once daily for successive 6 days in both RS group and 3-MA group. In 3-MA group, 3-MA (2 μL) was injected daily before seizures induced.Neural-behavior changes were observed with double-blind method including swimming development, open field test and Morris water maze analysis. Bcl-2 and Beclinl protein levels in hippocampus were detected by western blot method at P50. ResultsThe total scores of swimming behavior in RS rats were decreased significantly compared with those of control and 3-MA rats ( control: 7. 44 ±1. 13, RS: 5.06±1.63, 3-MA: 7.33 ±1.08, F=16.19, P<0. 01) . The start-latency time of open filed behavior in RS rats ( 13. 33 ±6. 69) were increased significantly compared with that of control (7. 11 ±2. 37) and 3-MA rats (9. 91 ±4. 23) (F=4. 39, P<0. 05). The escape latency was significantly longer in rats of RS group than that of control and 3-MA rats on the 4th and 5th days (P < 0.05). The level of Bcl-2 in hippocampus of RS group (0. 587 +0. 139) were significantly lower than that of control (0. 782 +0. 083) and 3-MA groups (0. 799 + 0. 163) (F =4. 7 1, P < 0. 05 ). There were no significant differences in the level of Beclin1 protein in hippocampus among the three groups ( F =0. 27, P > 0. 05 ).Conclusions Pretreatment with autophagy inhibitor 3-MA in acute phase of neonatal seizures could significantly improve neurobehavioral capacity, which might be associated with the increased in the level of Bcl-2 protein in hippocampus.

4.Characteristics of fertility changes in women with advanced polycystic ovary syndrome
Journal of Chinese Physician 2021;23(1):142-145
Polycystic ovary syndrome (PCOS) is the most common endocrine dysfunction in women of childbearing age. It is considered to be a heterogeneous, multi-faceted disease with polycystic ovarian changes, hyperandrogenism, and endocrine. Clinical features such as dysfunction and metabolic syndrome, due to the presence of ovulation dysfunction, seriously affect the fertility of women with PCOS. With the increase of age, the fertility decline of females is mainly related to factors such as the decrease in the number and quality of follicles, the decrease in the number of available embryos, the decrease in transplant rate and the increase in abortion rate. The existing literature does not agree on the fertility window of elderly PCOS patients. This paper reviews several literatures and discusses the reproductive window problems of elderly PCOS patients.

Circulating tumor cells (CTCs) mediate distant metastasesof many kinds of cancer.The detection and characterization of CTC through different enrichment and isolation methods play important roles in assessing of prognosis, monitoring of therapy response and decision making of personalized treatment.With the development of continued research, detection of CTC may become a routine test for therapeutic decision making of cancer.
6.Long-term effects of bubble baths on seizure-induced neurobehavioral deficits in newborn rats and related gene expressions in the hippocampus
Chinese Journal of Physical Medicine and Rehabilitation 2012;34(4):259-263
Objective To explore the long-term effects of bubble baths on seizure-induced neurobehavior deficits and the expression of apoptotic/autophagic marker B cell lymphoma/leukemia-2 ( Bcl-2 ),Beclin-1,and plasticity-related gene-1 ( PRG-1 ) in newborn rats. MethodsSixty rats aged 6 days were randomly divided into 4 groups:a control group (CON),a control hydrotherapy group (HCON),a recurrent-seizure group (RS) and a recurrent-seizure hydrotherapy group (HRS),with 15 in each group.Flurothyl was used to induce 30 min of seizures daily for 6 consecutive days in the RS and HRS groups.Rats in the CON and HCON groups were placed in the same container for equal duration without exposure to flurothyl.Rats in the HCON and HRS groups were given bubble baths for 28 consecutive days after the end of the last seizure.Neurobehavioral damage was observed using open field behavior at postnatal day 26 (P26) and Morris water maze performance at postnatal day 43 to 49 (P43-P49) and a single-blind method.PRG-1,Bcl-2 and Beclin-1 protein levels in the hippocampus were detected by Western blotting at postnatal day 50 (P50). Results①The average open field test scores of the RS rats decreased significantly compared with those of the CON and HRS rats at P26.②In the Morris water maze test the average latencies of all rats decreased gradually from the 1st to 5th days (d1 to d5) after establishment of seizure model.The average escape latency was significantly longer for rats of the RS group than for CON group rats at the 4th and 5th days ( d4 and d5 ) after establishment of seizure model.The escape latency was significantly shorter for rats of the HRS group than for RS group rats at d4.③The level of Bcl-2 protein in the hippocampus was much lower in the RS group than in the HRS and control groups.In addition,the expression of PRG-1 in the RS group was significantly higher than in the CON group. ConclusionsRecurrent prolonged seizures cause long-term neurobehavior deficits,which might be associated with the down-regulated expression of Bcl-2 and up-regulated expression of PRG-1 in the hippocampus.Bubble baths can improve the neurobehavioral sequelae from seizures,perhaps through up-regulation of hippocampal Bcl-2 expression.

Chinese Journal of Dermatology 2013;(2):100-104
Objective To evaluate the effect of a specific cathepsin B inhibitor,CA-074 Me,on the expression of cathepsin B in coxsackievirus B1-induced polymyositis in guinea pigs,and to elucidate the protective mechanisms of CA-074 Me on muscle fibers.Methods Polymyositis model was established in 32 guinea pigs by infection with coxsackievirus B1,which were then equally divided into 4 groups: γ-interferon group treated with intraperitoneal γ-interferon (150 000 IU per kilogram per day) from week 5 to week 8,polymyositis model group receiving no treatment,pseudo-intervention group treated with intraperitoneal sodium chloride physiological solution,CA-074 Me group treated with intraperitoneal CA-074 Me (4 mg per kilogram per day) for 7 days,after the infection with coxsackievirus B1.Eight guinea pigs receiving no infection or treatment served as the healthy control group.Blood samples and muscle tissue samples were obtained from the guinea pigs in the γ-interferon group on week 8 and in the other 4 groups on week 5.The serum level of muscle enzymes including creatine kinase (CK),CK-MM,aspartic transaminase (AST) and l-lactate dehydrogenase (LDH) were determined.Muscle tissue samples were studied by hematoxylin and eosin (HE) staining,and Envision two-step method was used to quantify the expression of cathepsin B and to numerate CD8+ T cells.The apoptosis in muscle cells was detected by terminal deoxynucleotide transferase-mediated dUTP-biotin nick end labeling (TUNEL).One-way analysis of variance (ANOVA) was conducted to compare the serum level of muscle enzymes,inflammation score of muscle and apoptosis index of muscular cells,and Pearson chi-square test to compare the count of CD8 + T cells and cathepsin B expression,among these groups.Results Polymyositis model was successfully established by infection with coxsackievirus B1 in the 32 guinea pigs with a marked increase in the serum level of the tested enzymes,especially in that of CK.In detail,the serum level of CK was (410.7 ±167.9) U/L in the healthy control group,significantly lower than that in the polymyositis model group ((3537.3 ± 2141.6) U/L,P < 0.05),pseudo-intervention group ((2222.0 ± 226.9) U/L,P < 0.05),γ-interferon group ((973.8 ± 423.2) U/L,P< 0.05) and CA-074 Me group ((814.0 ± 268.4) U/L,P< 0.05).Compared with the pseudo-intervention group,the γ-interferon group and CA-074 Me group showed a slight increase in the serum level of all the four enzymes (all P < 0.05).There was a significant elevation in the inflammation score of skeletal muscles in the polymyositis model group,pseudo-intervention group,γ-interferon group and CA-074 Me group compared with the healthy control group (1.75 ± 0.50,1.40 ± 0.55,2.38 ± 0.74 and 1.20 ± 0.45 vs.0.00 ± 0.00,all P < 0.05),with the most intense infiltration of inflammatory cells observed in the γ-interferon group.Moreover,the number of CD8 + T cells,cathepsin B expression and muscular cell apoptosis index were all significantly higher in the polymyositis model group,pseudo-intervention group,γ-interferon group and CA-074 Me group than in the healthy control group (all P < 0.05).Compared with the pseudo-intervention group,the CA-074 Me group showed less CD8+ T cells (42.3 ± 27.4 vs.68.0 ± 13.2,P < 0.05) and lower expression of cathepsin B (31.3 ± 6.7 vs.37.5 ± 9.2,P < 0.05),whereas the γ-interferon group exhibited elevated cathepsin B expression (49.3 ± 17.0 vs.37.5 ± 9.2,P< 0.05) and apoptosis index (40.1 ± 6.7 vs.25.4 ± 5.0,P< 0.05).Conclusions Cathepsin B is highly expressed in the guinea pig model of polymyositis,while CA-074 Me may protect muscle tissue in this model by downregulating the expression of cathepsin B and attenuating the inflammation and apoptosis induced by cathepsin B.

National Journal of Andrology 2014;20(5):423-429
OBJECTIVETo improve the sample collection methods and bacteriologic localization patterns in male genital tract infection, and to investigate the influence of specimen collection and pathogen isolation on the diagnosis and treatment of prostatitis.
METHODSWe collected the samples of the initial urinary stream, the third portion of the urinary stream, expressed prostatic secretion (ESP), and semen from 200 adult males with chronic prostatitis-like symptoms, inoculated them quantitatively in culture media for isolation of microorganisms, and evaluated their laboratory diagnostic significance according to the count of colonies and distribution of the isolates.
RESULTSA total of 468 strains of microorganisms were isolated from the samples, including 414 strains of bacteria spp (88.5%), 12 strains of fungi spp (2.6%), 40 strains of mycoplasma spp (8.5%), and 2 strains of chlamydia spp (0.4%). Pathogens were isolated from the ESP in 66 cases (33.0%), from the semen in 34 cases (17.0%), and from both the ESP and semen in 100 cases (50.0%). Only 1 species of pathogen was found in the ESP samples of 36 cases (18.0%), in the semen samples of 20 cases (10%), and in both the ESP and semen samples of 39 cases (19.5%); 2 species in the ESP samples of 30 cases (15.0%), in the semen samples of 14 cases (7.0%), and in both the ESP and semen samples of 60 cases (30.0%); and 3 species in both the ESP and semen samples of 1 case (0.5%).
CONCLUSIONMultiple microbial infection (MMI), multi-organ infection (MOI) and drug-resistance strains infection are common in patients with prostatitis-like symptoms, frequently leading to missed diagnosis and misdiagnosis in clinic and laboratory, and affecting the effect of antimicrobial therapy. MMI and MOI can be diagnosed and differentially diagnosed with the improved sample collection methods and bacteriologic localization patterns.
