This article reports the development of hyperosmolar hypernatremic hyperchloremic coma and acute renal failure in a male diabetic patient after recovery from hyperosmolar hypergly-cemic nonketonic coma, of which the cause is fluid retention in excess of urinary output due to the obstruction of lower urethra by diabetic neurogenic urinary bladder and hyper-plasia of prostate gland.By our experience each old diabetic man should be examined to confirm if he has neuro-genic urinary bladder and/or hyperplasia of prostate gland. Care should be taken to keep the balance of fluid intake and output provided that both of these conditions are present. The acute obstructive nephropathy can quickly ameliorate with release of the obstruction.

A simple, sensitive, selective, and reproducible liquid chromatography-tandem mass spectrometric method was developed for the simultaneous determination of repaglinide and metformin in human plasma using d5-repaglinide and d6-metformin as internal standards (ISs). After a simple protein precipitation using acetonitrile as the precipitation solvent, both analytes and ISs were separated on a Venusil ASB C 18 (150 mm x 4.6 mm, 5 microm) via gradient elution using acetonitrile--10 mmol x L(-1) ammonium acetate as the mobile phase. A chromatographic total run time of 7.5 min was achieved. Mass spectrometric detection was conducted with atmospheric pressure chemical ionization under positive-ion and multiple-reaction monitoring modes. The method was linear over the 0.2 to 60.0 ng x mL(-1) concentration range for repaglinide and over the 4 to 1 000 ng x mL(-1) range for metformin. For both analytes, the intra- and inter-accuracies and precisions were within the +/- 15% acceptable limit across all concentrations. The validated method was successfully applied to a clinical bioequivalence study.

A simple and rapid method was developed based on high performance liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) to determine sivelestat and its metabolite XW-IMP-A in human plasma. After a simple protein precipitation, the samples and internal standards were analyzed on a C18 column by a gradient elution program. The mobile phase consisted of 30% acetonitrile in methanol and 5 mmol · L(-1) ammonium acetate at a flow rate of 0.7 mL · min(-1). The mass spectrometric data was collected in multiple reaction monitoring mode (MRM) in the negative electrospray ionization. The standard curves were linear in the range of 10.0-15,000 ng · mL(-1) for sivelestat, and 2.50-1000 ng · mL(-1) for XW-IMP-A. The low limits of quantitation were identified at 10.0 and 2.50 ng · mL for sivelestat and XW-IMP-A, respectively. The intra- and inter-day precision were within 11.3% and 13.1% for sivelestat and XW-IMP-A, and accuracy was 0.3% and 0.6% for sivelestat and XW-IMP-A, within the acceptable limits across all concentrations. The method was successfully validated in the pharmacokinetic study of sivelestat in healthy Chinese volunteers.

Objective To investigate the protective effect of protocatechuic acid(PCA)on the PC12 cell model of Alzheimer’s disease(AD)and to explore its mechanism . Methods Amyloid beta peptide 1-42(Aβ1-42)fiber polymers were identified by immunofluorescence. After PC12 cells were stimulated with the Aβ1-42 fiber polymers, the cellular morphology was observed at different time points of hour 0, 3, 6, 9, 12, 24 , and the cellular viability was tested by methyl thiazolyl tetrazolium(MTT)assay to monitor the modeling condition. The effect of PCA on PC12 cells was detected after PC12 cells were pretreated with the different contentions of PCA. Autophagy-related marker Beclin1 protein level was detected by Western blotting method to investigate the protective mechanism of PCA. Results Aggregated white Aβ1-42 mass was stable at hour 12 and 24, and showed no significant difference between the two time points, the cell damage rate being 40%. Therefore, we defined culturing time being 12 and 24 hours as the modeling condition of AD model. The cell viability was increased with 200-800 μmol/L of PCA after culturing for 24 hours(P<0.01) , and the Western blotting results showed that the Beclin1 protein expression was up-regulated by PCA. Conclusion PCA prevents PC12 cells from Aβ1-42-induced toxicity, the mechanism being related with the increase of cellular autophagy.

To explore the mode of"one-day outpatient"based continuous management and examine its feasibility and preliminary effects for improving menopausal syndrome and mood among menopausal women.Clinical intervention study was conducted in Obstetrics and Gynecology Center of the Third Affiliated Hospital of Chongqing Medical University from May 2020 to May 2021.The continuous management mode of "one-day outpatient service" for menopause was constructed in terms of multidisciplinary resources, including offline "one-day outpatient" health education, online 7-week group continuous intervention on "healthy lifestyle" and offline half-day focus group interview. Pre-and post-scores of the modified Kupperman scale and the positive/negative emotional scale (PANAS) were measured to compare the status of menopausal syndrome and emotional experience of Seventy-eight female participants (40-60 years old), meanwhile, before and after comparison of the blood lipid and body composition indexes of participants were also performed. Paired t test or Wilcoxon signed rank test were used.Results show that the pre-and post Kupperman scores were 14.65±8.51 vs 10.26±5.83 ( t=-5.59, P<0.01), and the positive emotional scores (pre- 28.53±5.85 vs post- 30.13±6.30) were improved ( t=2.59, P=0.012) and negative emotional scores [pre- 20.5(10) vs post- 17.0(7)] were decreased ( Z=-5.09, P<0.01). The triglyceride level of participants declined from (1.27±0.54) mmol/L to (1.09±0.38) mmol/L ( t=-2.45, P<0.05). In addition, the body mass index(pre- 22.52±2.34 vs post- 22.06±2.22), percentage of body fat (pre- 31.72±6.22 vs post- 30.91±6.52)and Visceral fat area(pre- 83.96±30.26 vs post- 79.66±29.71) were all improved ( t=-3.58, t=-2.57, t=-2.59, P<0.05). Therefore,the mode of"one-day outpatient"based continuous management can effectively improve menopausal syndrome and adverse mood, reduce patients′ blood lipid, improve the body composition, and maybe contribute to the prevention of long-term chronic diseases.

With the development of society, the dietary pattern of Chinese residents gradually tends to be Westernized, and the disease spectrum has also been progressively changed into chronic non-communicable diseases like ischemic heart disease and stroke. Diet has been recognized as a common and modifiable factor for many chronic diseases. In this paper, the researches on dietary patterns and common chronic non-communicable diseases in recent years were summarized by searching the literature in Chinese and English databases in the past five years (2015-2020). This research integrated the outcome indicators, possible mechanisms, and research conclusions of dietary patterns and cardiovascular system, metabolic diseases, digestive system, locomotor system, and mental system in the past five years from the perspective of the human system. Dietary patterns characterized by red meat and processed meats, fast foods, sugary beverages were identified as risk factors for most diseases. In contrast, nutritional patterns characterized by vegetables, fruits, whole grains, fish were protective factors for most conditions. Meanwhile, it also put forward some problems that should be paid attention to in studying dietary patterns to provide a scientific basis for the follow-up research and the prevention and intervention of diseases.

AIM: To investigate the effect of ezetimibe combined with statins on residual lipoprotein-cholesterol (RLP-C) levels and major cardiovascular adverse events (MACE) in patients with acute coronary syndrome (ACS) after emergency intervention (PCI). METHODS: A total of 90 hospitalized patients with ACS and undergoing emergency PCI were randomly divided into two groups: 48 patients in the control group received atorvastatin, and 42 patients in the study group were additionally treated with ezetimibe. RLP-C level before and after treatment was detected. The occurrence of MACE events and adverse drug events during the treatment were obtained through regular follow-up. RESULTS: Compared with the control group, the level of RLP-C in the study group was significantly decreased (P<0.05), the incidence of MACE were significantly decreased (P<0.05), and adverse drug events were not increased. CONCLUSION: The combination therapy of ezedemibe and statins can reduce RLP-C level and MACE in ACS patients undergoing emergency PCI with less adverse reactions, which is worthy of promotion and application.

AIM:Bone morphogenetic protein 7(BMP7)reduces the expression of Yes-related protein 1(YAP1)by down-regulating Ajuba level and decreasing extracellular matrix(ECM)deposition.This study aimed to inves-tigate the influence of these factors on modifying the degree of renal fibrosis in rats with diabetic nephropathy.METH-ODS:Eighteen Sprague-Dawley(SD)rats were randomly divided into three groups:the normal control(NC)group,the diabetes mellitus(DM)group,and the DM group treated with BMP7 overexpressing adeno-associated virus(DM+rAAV-BMP7).Each group consisted of six rats.Diabetic kidney disease(DKD)was established in the DM and DM+rAAV-BMP7 groups by injecting 55 mg/kg streptozotocin(STZ)via the tail vein.NRK-52E cells were divided into three groups:the normal glucose(NG)group,the high glucose(HG)group,and the high glucose group treated with recombinant hu-man BMP7(HG+rhBMP7)group.Pathological changes in renal tissues were observed using hematoxylin and eosin(HE)and Sirius red staining.Immunohistochemical staining was performed to examine the expression sites of Ajuba and YAP1 in the renal cortex.Western blot analysis was conducted to determine the expression levels of BMP7,Ajuba,YAP1,colla-gen type Ⅲ(Col-Ⅲ),and fibronectin(FN)in the rat renal cortex and NRK-52E cells.RT-qPCR was used to measure the mRNA levels of Ajuba and YAP1 in the rat renal cortex.RESULTS:Biochemical indices revealed significantly ele-vated levels of blood glucose,serum creatinine,triglycerides,total cholesterol,and 24-hour urinary protein in the DM group compared to the NC group(P<0.05).In the DM+rAAV-BMP7 group,the levels of serum creatinine,24-hour uri-nary protein,triglycerides,and total cholesterol were lower than those in the DM group(P<0.05).Pathological staining demonstrated that the renal interstitium of the DM group exhibited inflammatory cell infiltration,fibrous tissue,collagen fi-ber deposition,disordered renal tubule arrangement,atrophy,and vacuolar degeneration,which were ameliorated in the DM+rAAV-BMP7 group.Immunohistochemistry revealed that Ajuba and YAP1 were mainly expressed in the cytoplasm and nucleus,with high expression in the cytoplasm of the DM group,which was significantly decreased in the DM+rAAV-BMP7 group.Western blot results indicated that the protein levels of FN,Col-Ⅲ,Ajuba,and YAP1 were up-regulated in the DM and the HG groups(P<0.05),but significantly down-regulated in the DM+rAAV-BMP7 group(P<0.05).RT-qP-CR results demonstrated that the mRNA levels of Ajuba and YAP1 were higher in the DM group and significantly lower in the DM+rAAV-BMP7 group(P<0.05).CONCLUSION:The overexpression of BMP7 can ameliorate renal fibrosis in rats with DKD.This effect is likely mediated by the down-regulation of Ajuba,reduction of YAP1 expression,and subse-quent inhibition of ECM deposition.
