AIM: A new HPLC-MS method was developed to determine finasteride in human plasma. METHODS: Two formulations of finasteride tablets were given to 20 healthy male volunteers according to a randomized 2-way cross-over design. The samples were extracted by ethyl acetate under basic conditions, then were separated by C18 column and determined by mass detector. RESULTS: The calibration curve of finasteride was linear and intra-day and inter-day RSD were less than 10 %. The pharmacokinetics parameters of the two formulations (4.5 ± 0.5) h for t1/2; (3.0 ± 0.7) and (2.8 ± 0.9) h for tmax, respectively. The results indicated that there was no significant difference on cmax, A UC0-24, t1/2 or tmax values between the two formulations. CONCLUTION: The relative bioavailability of tablets I with respect to tablets Ⅱ is (99.3 ± 9.2) % by the A UC0-24 measurement, and bioe quivalence is observed between the two tablets.

Objective To explore the clinical value of serum procalcitonin (PCT)-based antibiotic therapy in the second-classedexacerbations of chronic obstructive pulmonary disease (AECOPD). Methods 240 patients diagnosised as AECOPD were randomized to the PCT group and the control group. Serum PCT levels of patients from the PCT group were measured 1 h after hospitalized and the third, fifth, eighth day respectively. When PCT < 0.1 μg / L, patients will stop taking antibiotics and initiated while PCT≥0.1 μg / L. Antibiotic treatment in the control group was based on guidelines of COPD diagnosis and treatment. Results Duration of antibiotic therapy and hospitalization were respectively 5.6 ± 1.4 and 8.2 ± 1.1 days in the PCT group, 9.2 ± 2.2 and 11.4 ± 2.5 days in the control group (both P < 0.05). Mean costs of hospitalization expensesand antibiotic therapy were 5700 ± 201 and 1650 ± 189) yuan in the PCT group, 6210 ± 220 and 2350 ± 210 yuan in the control group (both P < 0.05). The clinical effective rate, times of exacerbation, one-year ΔFEV1, the 1-year hospitalization rate and time to next exacerbation all showed no significant differences between the two groups. Conclusion PCT-guided antibiotic treatment reduces antibiotic use inthe second-classed acute exacerbations patients.

Recently,an increasing number of studies have found that matrix metalloproteinase (MMPs) are closely related to the severity,diagnosis and prognosis of a variety of diseases. MMPs have therefore also gained increasing attention as a potential biomarker. In this paper,the application of MMPs in the diagnosis of tumors,cardiovascular diseases,inflammatory diseases and neurodegenerative diseases was summarized,and three types of detection methods based on RNA level,protein level and hydrolase activity of MMPs were introduced,which aims to provide some theoretical reference for the study of clinical application of MMPs detection.

Objective To assess the predictive value of Berden classification in ANCA associated glomerulonephritis.Methods Patients with confirmed ANCA associated glomerulonephritis were included,by retrieving the medical database in Peking Union Medical College Hospital from January 2000 to May 2015.Their detailed information during hospitalization and follow-up was recorded.The patients were divided into four categories based on Berden classification.The differences in clinical characters,renal function and response for treatment were compared.Results Among the 88 patients with ANCA-associated glomerulonephritis,19 (21.6％),21 (23.9％),32 (36.4％)and 16 (18.2％) patients were classified as focal,mixed,crescentic and sclerotic category.22 patients developed ESRD,and 19 patients died during follow up (1 patient developed ESRD before died).The mean estimated glomerular filtration rate (eGFR) at baseline was 68.04,25.45,30.04,15.16 ml·min-1·(1.73 m2)-1 (P ＜ 0.05) in focal,crescentic,mixed and sclerotic category,respectively.During follow-up period,focal category always had the best renal function,while sclerotic category had the worst renal function.Crescentic category and mixed category were similar and in the middle.Remission rate at 6m was 62.5％,73.7％,57.5％,30.8％(P ＞ 0.05).And crescentic category had the greatest improvement in eGFR at 6m.Conclusions Focal category had relatively preserved renal function and favorable renal outcome,while the sclerotic category had the worst renal outcome.Crescentic and mixed category had an intermediate outcome.We support the use of the Berden classification in predicting the renal prognosis of patients with ANCA associated glomerulonephritis.

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a sleep breathing disorder caused by obstruction of the upper airway during sleep from various causes. At present, the diagnosis and treatment of OSAHS are insufficient. OSAHS causes cognitive decline due to excessive oxidative stress and inflammatory response caused by sleep breathing disorder, and its alteration of the brain gray matter area may be related to cognitive dysfunction. This review investigates the correlation between cognitive dysfunction and brain gray matter areas changes in OSAHS, and elucidates the underlying mechanisms, which provide a theoretical basis for early clinical diagnosis and treatment.

Objective To investigate the clinical and pathological features of patients with a combination of Sjogren's syndrome (SS) and antineutrophil cytoplasmic antibody (ANCA) associated vasculitis with renal involvement.Methods By searching the Peking Union Medical College Hospital medical database and literature between January 1990 and June 2017,patients had a combination of SS and ANCA associated vasculitis with renal involvement were included.Data of clinical information,autoimmune antibodies,renal manifestations and renal pathology were retrieved and analyzed.Results Eighteen patients were enrolled:4 from our hospital and 14 from literature.SS was diagnosed no later than ANCA associated vasculitis in all the patients,among which 83.3％(15/18) of patients had extra-glandular and extra-renal organs involved.All the patients were tested positive for myeloperoxidase (MPO)-ANCA,and only two were protein 3 (PR3)-ANCA positive concurrently.The positivity rates of antinuclear antibody (ANA),rheumatoid factor (RF),anti-SSA antibody,and anti-SSB antibody were 83.3％(15/18),55.6％(10/18),77.8％(14/18),and 38.9％(7/18),respectively.The renal manifestations were characterized by renal insufficiency with a median serum creatinine of 174 μmol/L,hematuria,moderate proteinuria with a median 24 hour urine protein of 1.70 g,and necrotizing vasculitis with oligo-immune complex and varying degrees of interstitial damage in pathology.Conclusions A combination of Sjogren's syndrome and ANCA associated vasculitis with renal involvement is rare in clinical setting,and almost all of the patients are MPO-ANCA positive,with high probability of ANA positivity and extra-glandular involvement.Physicians should beware of ANCA associated glomerulonephritis in SS patients with inexplicable renal dysfunction and renal biopsy should be carried out in time.

Esophageal squamous cell carcinoma (ESCC) is one of the leading causes of cancer death worldwide. It is urgent to develop new drugs to improve the prognosis of ESCC patients. Here, we found benzydamine, a locally acting non-steroidal anti-inflammatory drug, had potent cytotoxic effect on ESCC cells. Benzydamine could suppress ESCC proliferation in vivo and in vitro. In terms of mechanism, CDK2 was identified as a target of benzydamine by molecular docking, pull-down assay and in vitro kinase assay. Specifically, benzydamine inhibited the growth of ESCC cells by inhibiting CDK2 activity and affecting downstream phosphorylation of MCM2, c-Myc and Rb, resulting in cell cycle arrest. Our study illustrates that benzydamine inhibits the growth of ESCC cells by downregulating the CDK2 pathway.
