Objective To confirm the expression and localization of COX-2 gene in mature rat testis,as COX-2 not only plays a central role in inflammation by up-regulating the synthesis of prostaglandins,but also mediates critical reproductive functions by other mechanisms. Methods In the mature Wistar rats,COX-2 expression and its localization were examined by using immunohistochemistry,RT-PCR and Western-blot. Results The results of RT-PCR and Western-blot showed that COX-2 mRNA and its protein exist in the testis. Expression of COX-2 was localized in spermatogenic cells on immunohistochemical study.No COX-2 expression in sertoli cells and leydig cells was found. Conclusions The present study confirmed the expression of COX-2 in rat testis and its localization in spermatogenic cells.These suggest that COX-2 may play a role in spermatogenesis.

Objective To explore whether apply selective perineal skin preparation or not is feasible for patients with coronary heart disease (CHD) before percutaneous coronary intervention (PCI).Methods Divided patients with CHD before PCI into the experimental group (801 cases) and the control group(798 cases) according to the hospital number.Selective perineal skin preparation was used in the experimental group,while the right forearm skin preparation was used in all the patients in the control group.The rate of skin preparation and the care hours in the two groups were compared.Results The care hours of skin preparation in the experimental group was (5.58±0.30) h,which was significant shorter than that in the control group,(66.50±1.50) h,t=-1127.03,P＜0.05.Conclusions Before PCI,for patients with CHD,applying selective perineal skin preparation is feasible.It can not only reduce care labor,decrease nursing costs,but also relieve nurse-patient psychological pressure,cut back patients' expenses;and without percutaneous entrance infection.

Both motor therapy and functional electrical stimulation was used to treat the patients with hemiplegia. In 43 patients 17 cerebral haemorrhages, 26 cerebral infarctions and 7 traumatic cerebral injuries and haematomas male 28, female 15,were included in our studies. Therapy began in 1 to 2 weeks after lesion in 23, 2 to 5 weeks in 14, 3 -4 months in 3,6 months in 1,8 months in 1 and 1 year in 1. The results were evaluated by Barthel Index before and after the treatment,increasing from 41.02 ±20.58 pretreatment to 85.70±16.46 post-treatment with 22.58±15.10 times

ObjectiveTo evaluate the value of bispectral index(BIS) monitoring during sedation in the ICU.Methods60 patients in ICU were randomly divided into three groups. By transfusing propofol and midazolam with injecting pump, the BIS of groups Ⅰ,Ⅱ and Ⅲ were controlled within 75～85, 65～75 and 55～65, respectively. ResultsCompared with the pre-sedation, there was no remarkable change in the patients of groups Ⅰ and Ⅱ after sedation(P>0.05)while there was remarkable change in the patients of group Ⅲ(P<0.05).The average score of Ramsay in groups Ⅰ, Ⅱ and Ⅲ were 2.2, 3.4 and 4.6 while the dose of propofol were (9.54±2.43) μg/kg·min, (12.69±3.12) μg/kg·min, (14.18±2.91) μg/kg·min and the dose of midazolam were (0.23±0.09) μg/kg·min, (0.25±0.07) μg/kg·min, (0.28±0.11) μg/kg·min, respectively.ConclusionThe application of BIS can make good judgement in the sedation, which showed different choices to different needs to obtain optimistical sedation effect.

To study the antiviral effect of Hypericum perforatum L. extract (HPE) on influenza A virus (IAV) (H1N1) in vitro and in vivo. Cytopathic effect (CPE) and neutral red (NR) dye uptake were used to examine the antiviral effect of HPE on Madin Darby Canine Kidney (MDCK) cells which were infected with IAV in vitro. HPE was effective against influenza A virus (IAV) in vitro, with a 50% effective concentration (EC50) of 40 μg/mL. The mean 50% cytotoxic concentration (CC50) in the MDCK used in these experiments was 1.5 mg/mL. Ribavirin was run in parallel with EC50 values of 5.0 μg/mL; the mean CC50 for ribavirin was 520 μg/mL. Oral gavage administrations of HPE or ribavirin to mice infected with the IAV were highly effective in preventing death, slowing the decline of arterial oxygen saturation, inhibiting lung consolidation and reducing lung virus titers. The minimum effective dose of HPE in these studies was 31.25 mg/kg/day, which was administered twice daily for 5 d beginning 4 h prior to virus exposure. Below a dosage of 2000 mg/kg/day, almost all treated mice survived, which suggests that HPE is of low toxicity. Ribavirin's minimum effective dose was 40 mg/kg/day with the LD50 determined to be 200 mg/kg/day. Delay of the initiation of either HPE or ribavirin therapy, using approximately 1/3 LD50 dose each time, could still be protective as late as 48 h after exposure to the IAV. While both agents appeared to have similar efficacy against IAV infections, HPE was considered to be less toxic and may warrant further evaluation as a possible therapy for influenza.

Objective:To explore the clinical characteristics and treatment of a family with inherited generalized epilepsy with febrile seizures plus (GEFS + ) caused by the KCNT2 gene mutation and review the literature. Methods:Clinical data of a child with GEFS + and his family members who visited Department of Pediatric Neurology, Guangzhou Women and Children′s Medical Center in May 2019 were collected.DNA samples were collected from the peripheral blood of the proband, his parents, his elder brother, and his maternal grandparents, and genetic analysis and verification were performed using the next-generation sequencing technique.Using " KCNT2" as the key word, literature was retrieved from PubMed, China National Knowledge Infrastructure and Wanfang databases (up to August 2019). Results:The proband was a 3-year-old boy who was admitted to Guangzhou Women and Children′s Medical Center because of frequent epileptic seizures in the past 5 months.He presented with a binocular gaze and experienced 3 to 8 times of extremities myoclonic-spastic epileptic attacks every day.He had a history of 3 times of febrile seizures at the age of 2 years old.His seizures were refractory to Sodium valproate, Topiramate, Nitrazepam and Levetiracetam.His elder brother and mother had a history of childhood febrile seizures.Other members in the family had no history of convulsion.Ictal electroencephalogram showed general 1 Hz high voltage spike-slow waves.A heterozygous nonsense mutation of KCNT2 gene c. 574C>T(p.Q192X) that was never reported previously was detected in the proband, his brother, mother and maternal grandmother.Furthermore, no other family members carried the mutation at the c. 574 locus of the KCNT2 gene.No article in Chinese was found, and 2 articles in a language other than Chinese provided the complete data of 3 sporadic cases.Together with 4 cases in the family studied in this article, there were 7 cases and 4 mutation sites in KCNT2 gene.Of these mutations, there were 3 missense mutations and 1 nonsense mutation.Three sporadic patients presented with early infantile epileptic encephalopathy.The family of this study was characterized with febrile seizures and febrile seizures plus. Conclusions:A de novo mutation and phenotype of the KCNT2 gene is found in a family with GEFS + .It would expand the gene mutation spectrum and provide basis for family genetic counseling. KCNT2 mutation induced GEFS + is refractory to antiepileptic drugs.
