Objective To explore the correlative factors and management of secondary high intraocular pressure(IOP) after vitreoretinal surgery for proliferative diabetic retinopathy(PDR). Methods The data of 51 patients(54 eyes) with PDR after vitreoretinal surgery were collected.The incidence of secondary high IOP was obtained,and the correlative factors leading to high IOP were analysed.Besides,the therapeutic effects of management were observed. Results Twenty-six patients(26 eyes) experienced postoperative high IOP,with the incidence of 48.15%(26/54).It was revealed that the preoperative retinal detachment,the combined performance of crystal phacoemulsification,the practice of intraocular tamponade and the postoperative posterioruveitis were related to the occurrence of high IOP(P

Objective To investigate the mechanism of Glutathione in the prevention of ventilator-associated lung injury.Methods 30 mechanical ventilation patients who were healthy before were selected and randomly divided into the two groups.Group A was the high tidal volume group:10mL/kg;group B was used the tidal volume plus the injection of Glutathione(2.4g/d).After 48 hours,we collected lavage fluid and use Coomassie brilliant blue to detect the protein content of alveolar lavage fluid of the two groups.Results There was a significant difference (P<0.01)between the two groups.The protein content in group A[(9.90 ±2.25)g/L]was higher than that of group B [(4.17 ±0.39)g/L],and there was statistically significant (P<0.01).Conclusion Glutathione can reduce the incidence of ventilator-associated lung injury and prevent the occurrence of ventilator-associated lung injury.

OBJECTIVE:To provide reference for continuous improvement of drug counseling and pharmaceutical care. METH-ODS:220 cases of drug counseling answered by inpatient general pharmacist were collected from our hospital during 2012-2013, and the contents of drug counseling were classified and analyzed. RESULTS:Among consultants,73.18% of them were physi-cians;the type of drug involved mainly were antibiotics,accounting for 42.73%;main contents of drug counseling included drug selection,usage and dosage,accounting for 47.27%. CONCLUSIONS:Pharmacists provide drug counseling for physicians and nurses,answer various questions about usage,and guide rational drug use so as to enhance the communication between pharma-cists and physicians,nurses,and promote rational drug use in the clinic.

The purity of 4,4′-dimethoxy-5,6,5′,6′-bis (methylenedioxy)-2′-morpholine methylenebiphenyl-2-methyl formate methanesulfonate (IMH), a new drug for fatty liver treatment, was determined through differential scanning calorimetry (DSC). Analysis of two-factor non repeatability method was performed in the investigation the effects of two factors (heating rate and sample weight) on purity determination. The DSC experimental parameters were optimized as follows: heating rate was 10 ℃·min^-1, temperature range was 150-300 ℃, sample weight was 2.0-4.1 mg, and N₂ flow rate was 80 mL·min^-1. The linear correlation coefficient (r) of this DSC method was 0.999 8. The RSD value (n = 6) of precision was 0.03%. The standard value and uncertainty of the purity results of the multiple batches of IMH drugs were (99.74 ± 0.29)%, (99.91 ± 0.28)%, (99.90 ± 0.28)%, and (99.81 ± 0.28)% with inclusion factor (K) of 2 and confidence probability (P) of 0.95. The results were basically consistent with the results of the mass balance method. The DSC mehod is a simple, rapid and accurate method, and provides a new reference method for determining the purity of IMH drugs, improves the accuracy and reliability of purity determination.

Percutaneous coronary intervention(PCI) has become one of the most important therapeutic methods for atherosclerotic heart disease(AHD),but the following complications such as stent thrombosis and restenosis af- fected its long-term efficacy.Platelet activation was a key component of thrombosis of during perioperative period PCI.As one of the most effective antiplatelet drugs,clo- pidogrel has been established its important role in preven- ting thrombosis during perioperative period of PCI.After several large-scale clinical trials in recent years.

OBJECTIVETo study the effect of Guishen Pill (GSP) on expression levels of Oct-4, MVH, and Egr-1 in mice with diminished ovarian reserve (DOR).

METHODSTotally 40 female C57BL/6J mice were randomly divided into 4 groups, the normal control group, the model group, the GSP group, and the dehydroepiandrosterone (DHEA) group, 10 in each group. Pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG), and prostaglandin F2α (PGF2α) were sequentially administrated to produce superovulation. The DOR model was established by exposing to ozone inhalation. Mice in the GSP group were intragastrically administered with GSP at 0.3 mL. Those in the DHEA group were intragastrically administered with DHEA at 0.3 mL. Equal volume of normal saline was intragastrically administered to mice in the normal control group and the model group. All mice wer treated for 21 days. Serum levels of estrogen (E2), progestogen (P), and anti-Müllerian hormone (AMH) were measured by ELISA. Changes of Oct-4, anti-AMH, and early growth response gene-1 (Egr-1) mRNA in ovaries were dtected by Real-time PCR.

RESULTSCompared with the model group, serum levels of E2, P, and AMH, as well as contents of estrogen receptor (ER), progestogen receptor (PR), MVH, and Oct-4 mRNA significantly increased in the GSP group and the DHEA group (P < 0.05).

CONCLUSIONGSP could improve expression levels of Oct-4, MVH, and Egr-1 mRNA in DOR mice and their ovarian function.

Objective: To analyze the epidemiological characteristics of influenza clusters in Hangzhou from 2018 to 2019, so as to provide references for the prevention and control of influenza. Methods: The data came from the epidemic investigation reports of influenza clusters in Hangzhou from the 27th week of 2018 and the 26th week of 2019. The time distribution, school types, population distribution and etiology of influenza were analyzed. Multivariate logistic regression model was employed to analyze the influencing factors for the attack rate of influenza clusters. Results: During the surveillance season, a total of 231 school influenza clusters involving 4 233 cases were reported. The median of the attack rate was 21.74%. The peak of the clusters was in March 2019, with 89 events and 1 476 cases ( 34.87% ). The clusters occurred mainly in primary schools ( 188 events, 81.39% ) and were mainly caused by Victoria-like strains of influenza B virus ( 84 events, 36.36% ). The multivariate logistic regression analysis indicated that infection of teachers increased the risk of high attack rate ( OR=3.133, 95%CI: 1.180-8.320 ), and kindergartens had higher risk of high attack rate than primary schools ( OR=4.123, 95%CI: 1.579-10.763 ). Conclusions The influenza clusters in Hangzhou from 2018 to 2019 is mainly caused by Victoria-like strains of influenza B virus. Kindergartens and teachers are the key points for the prevention and control of influenza clusters.
