Objective To study and investigate the comprehensive application value of urinary tract dilata-tion combined with cavity technique in patients with ankylourethria.Methods 70 male patients with ankylourethria were collected as the research object,and they were randomly divided into the control group(ordinary urethral dilata-tion treatment group ) of 35 cases and observation group (urinary tract dilatation combined with cavity technique group)of 35 cases by numeration table,then the treatment effect of different stricture length,urodynamic indexes and life quality state before and after the treatment of the two groups were evaluated and compared.Results The cure rates and recurernce rates of the observation group were 91.43% and 2.86%,respectively,which were better than that 68.57% and11.43% of the control group(χ2 =5.396,6.502,all P<0.05).The urodynamic indexes and life quality state at first,third and sixth month after the treatment were all better than those of the control group (t =4.613,4.902,5.263,3.180,all P<0.05).Conclusion The comprehensive application value of urinary tract dila-tation combined with cavity technique in patients with ankylourethria is higher,and it is more benefit for the improve-ment of urodynamic indexes and life quality state.

Using a bioassay-guided fractionation technique, two compounds were isolated from the roots of Incarvillea younghusbandii Sprague through silica gel, reverse-phase C18 column chromatography and reverse-phase HPLC. Their structures were identified as acteoside (1) and isoacteoside (2) by ESI-MS, GC-MS, 1D- and 2D-NMR. 1 and 2 showed *OH scavenging capacity similar with benzoic acid, higher O2*- (or *OH) scavenging capacity than ascorbic acid, far higher hepatic LPO inhibitory activities than 2, 6-di-tert-butyl-4-methylphenol (BHT) or ascorbic acid, and more powerful effect on protecting erythrocytes from oxidative damage than ascorbic acid. The *OH scavenging capacity was positively proportional to the concentrations of 1 and 2 ranging from 0.015 6 to 0.500 0 mg x mL(-1). The hepatic LPO inhibitory activities increased with the increasing concentrations of 1 and 2 from 0.001 9 to 0.250 0 mg x mL(-1), but decreased slightly with the increasing concentration from 0.250 0 to 1.0000 mg x L(-1).

Objective To analyze the clinical feature and prognostic predictors of disseminated herpes zoster.Methods A retrospective study was carried out on 76 patients with disseminated herpes zoster collected from 2005 to 2012 in the Department of Dermatology,Anhui Provincial Hospital.Statistical analysis and comparisons were done.Results The incidence rate of disseminated herpes zoster was highest in the three age groups:70-79 years,30-39 years,and 60-69 years.Of these patients,59.21％ suffered from complications,and 44.74％ from postherpetic neuralgia.Logistic regression analysis showed that the occurrence of complications was significantly associated with age and impaired cellular immune function,and the incidence of postherpetic neuralgia with age,impaired cellular immune function and presence of underlying diseases.Conclusions There is a high incidence of complications in patients with disseminated herpes zoster,and impaired cellular immune function may be an important factor affecting its prognosis.

Objective To analyze the clinical features, diagnosis, treatment and prognosis of neurosyphilis. Methods Clinical data on and laboratory findings in 18 cases with neurosyphilis collected in the Affiliated Provincial Hospital, Anhui Medical University from 2006 to 2008 were retrospectively studied.Results Among the 18 patients, 3 sufferred from asymptomatic neurosyphilis, 1 from meningeal syphilis, 7 from meningovascular syphilis, 5 from paralytic dementia, and 2 from intracranial space-occupation. Toluidine red unheated serum reagin test (TRUST) and Treponema pallidum particle agglutination test (TPPA) of sera were positive in all the patients; cerebrospinal fluid (CSF) TRUST was positive in 16 patients, and CSF TPPA in all patients. An increase was observed in CSF leukocyte count in 7 patients and in CSF protein in 13 patients.The findings on cerebral magnetic resonance imaging (MRI) mainly included demyelination, brain atrophy,cerebral infarction, etc. All the patients, except 2 with a TRUST titer of 1:4, experienced a 4-fold decrease in TRUST titer within a 3-month follow up. Clinical symptoms of neurosyphilis improved in all patients except 1 with paralytic dementia. Conclusions The diversity of clinical manifestations usually leads to the misdiagnosis of neurosyphilis, which should be diagnosed based on comprehensive analysis of clinical characteristics as well as laboratory and imaging findings. Early diagnosis and treatment are beneficial to its prognosis.

Objective To investigate the molecular mechanism of solanine-induced apoptosis of prostate cancer cells Du145 and LNCaP.Methods The effects of solanine on the viability of Du145 and LNCaP cells were evaluated by MTT assay.The generation of intracellular reactive oxygen species (ROS) and solanine-induced apoptosis were measured by flow cytometry.The protein levels of p38 and p-p38 expressions were examined by Western blot.Results Solanine significantly inhibited the viability of Du145 and LNCaP cells in a dose-dependent manner (P＜0.01).The inhibition of solanine on cell viability was suppressed by the ROS scavenger NAC.ROS generation,apoptosis and phosphorylation of p38 were induced by treatment with solanine at 40 μmol/L for 24 h.The expression of p38 and solanine-induced apoptosis were suppressed by NAC and SB203580.Conclusion Solanine induces the apoptosis of human prostate cancer cell via the RO.S-p38 signaling pathway.

Objective To systematically evaluate toxicities of nifedipine in pregnant women with hypertension, and provide references for nifedipine’s clinical safety application. Methods Study was conducted with data from US food and drug administration adverse event reporting system（FARES） database from January 1, 2015, to March 31, 2021. Information component （IC） and reporting odds ratio（ROR）methods were applied for signal mining. Results Finally, a total of 539278 records of pregnant women with hypertension were selected for analysis, and 70 positive adverse drug event signals were detected. Premature delivery （IC₀₂₅=2.87，ROR₀₂₅=9.52）, pre-eclampsia （IC₀₂₅=1.82，ROR₀₂₅=3.82） and fetal growth restriction （IC₀₂₅=2.37，ROR₀₂₅=5.69）were positive adverse events with higher frequency. Polydactyly（IC₀₂₅=3.13， ROR₀₂₅=10.05）, fetal death（IC₀₂₅=2.93，ROR₀₂₅=8.57）and premature delivery（IC₀₂₅=2.87，ROR₀₂₅=9.52）were positive adverse events with higher intensity. Vascular resistance systemic increased, small for dates baby and fetal death corresponded to higher death rates. Conclusion Nifedipine-associated drug toxicities were detected in pregnant women with hypertension, and some adverse events with high frequency and high death rate were deserved further attention by medical staffs.

To observe the hypoglycemic effect of Qizhi Jiangtang capsule in rats with type 2 diabetes, and investigate the preliminary mechanism of its hypoglycemic effect, type 2 diabetes rat models were established by high glucose and high fat combined with small dose of streptozotocin (STZ). After continuous administration for 6 weeks, blood glucose, and glycosylated serum protein (GSP) levels were detected in all of the animals; immunohistochemistry assay was used to detect the number of islet β cells; Western blot assay was used to detect the protein expression levels of insulin receptor (InsR), phosphoinositide-3 kinases (PI3K), glucose transporter-2 (GLUT2) and phosphorylated Jun N-terminal kinases (p-JNK)in hepatic tissues. The results showed that Qizhi Jiangtang capsule could reduce the blood sugar and GSP levels in serum in animals with type 2 diabetes mellitus, increase the level of insulin in serum and number of islet β cells, increase the protein expression levels of InsR, PI3K and GLUT2, and reduce the level of p-JNK protein expression. In conclusion, Qizhi Jiangtang capsule has relatively stable hypoglycemic effect, and the mechanism may be associated with increasing the number of islet β cells and level of insulin in serum, up-regulating the protein expression levels of InsR, PI3K and GLUT2, down-regulating the level of p-JNK protein expression in hepatic tissues, and reducing the level of insulin in hepatic tissues.

The effect of Qizhi Jiangtang vapsule (QJC) on degree of dermal ulcer cicatrization in 2 type diabetic rats was studied. Except the rats for blank group, other male Wistar rats were used to establish type 2 diabetic model by feeding with high sugar and high fat diet for four weeks and intraperitonally injecting with 30 mg•kg⁻¹ streptozotocin (STZ). After that, the rats were divided into balanced groups according to blood sugar, and received corresponding drugs for treatment for 8 weeks. At the end of week 8, 2 cm diameter circular incision was done on the back of rats. After that, the rats were administered continuously for10 days. Area of ulcer surface was detected every two days. After the last administration, wound granulation tissues were cut down to conduct pathological examination and detect the expression of VEGF, PI3K, p-ERK protein in wound tissues. The results showed that compared with the model group, after application of Qizhi Jiangtang capsule (2.24 g•kg⁻¹), the wound was significantly reduced on day 6 and day 10 of wound formation; inflammation reaction on ulcer surface was significantly reduce; Qizhi Jiangtang capsule can increase VEGF expression in the wound tissues of diabetic rats, and inhibit ERK phosphorylation. It can be concluded that Qizhi Jiangtang capsule can promote skin ulcer healing for diabetes rats, and its mechanism may be related to regulating the expression of VEGA and p-ERK proteins.

The medical delivery team and flight crew were kept free of infection, passengers maintained zero cluster infections and no unexpected adverse events during the air transport.Conclusions:Our results indicate how to carry passengers in a scientific and orderly way is crucial for avoiding the transmission risks of the epidemic of COVID-19 among working staffers and passengers during air transportation.

Objective::To explore the feasibility of the rapid identification system(MALDI-Biotyper System) of microorganisms for rapid identification of Pseudomonas aeruginosa and clinical isolation of Staphylococcus aureus. Method::Identification quality control and clinical isolation were conducted for drug resistance of S. aureus by microbial rapid identification system and broth dilution method. The scores of microbial rapid identification system were compared with the MIC value of broth dilution method. The drug resistance of P. aeruginosa was simultaneously identified to determine the accuracy and applicability of the rapid identification system of microorganisms. Result::The scores of the microbial rapid identification system showed that the score of sensitive quality control strain S. aureus was higher than 2.000, and the that of resistant strain of methicillin-resistant S. aureus(methicillin-resistant S. aureus, MRSA)was between 1.700 and 2.000.The score of clinically isolated S. aureus was between 1.700 and 2.000, which suggested the drug resistance and was consistent with the MIC value of the broth dilution method. At the same time, the systemic identification value of the P. aeruginosa, which is independent of the quality control sensitive strain, was greater than 2.000, showing sensitivity and it was a sensitive strain itself, which was consistent with the results. Conclusion::The microbial rapid identification system scoring method can be used for the rapid identification of the drug resistance of S. aureus and P. aeruginosa.
