ABSTRACT
Objective:To investigate the influence of T2DM Spleen-qi Deficiency syndrome on Ankle-Brachial Index (ABI).Methods:The clinical data of 298 patients with T2DM who were hospitalized in Dongzhimen Hospital, Beijing University of Chinese Medicine from January 2019 to December 2021 were retrospectively analyzed. According to the diagnostic criteria of spleen-qi deficiency syndrome, the patients were divided into two groups: spleen-qi deficiency syndrome group and non-spleen-qi deficiency syndrome group. There were 142 patients in the spleen-qi deficiency syndrome group and 156 patients in the non-spleen-qi deficiency syndrome group. The differences of ABI between the two groups were compared, and the correlation between spleen-qi deficiency syndrome and clinical indicators (gender, age, body mass index, course of diabetes, history of hypertension, smoking history, fasting glucose, total cholesterol, triglyceride, platelet, hemoglobin, serum albumin, blood urea nitrogen, serum creatinine, estimated glomerular filtration rate) and ABI in T2DM patients was analyzed.Results:The left ABI [1.09 (1.00, 1.19) vs. 1.13 (1.03, 1.22)] and the right ABI [1.09 (0.96, 1.17) vs. 1.12 (1.02, 1.20)] in T2DM spleen-qi deficiency syndrome group were significantly lower than those in non-spleen-qi deficiency group ( P<0.05).The left ABI was significantly correlated with spleen-qi deficiency syndrome ( r=0.122, P=0.035) and estimated glomerular filtration rate ( r=0.137, P=0.018), and the right ABI was significantly correlated with spleen-qi deficiency syndrome ( r=0.123, P=0.034) and PLT ( r=-0.115, P=0.047). After correcting for other confounding factors by multiple linear regression analysis, there was significantly correlation between spleen-qi deficiency syndrome and ABI. Conclusion:Compared with the non-spleen-qi deficiency syndrome group, T2DM patients in the spleen-qi deficiency group had a lower ankle-brachial index and were more likely to develop peripheral arterial disease.
ABSTRACT
Zwitterionic sulfobetaine-based monolithic stationary phases have attracted increasing attention for their use in hydrophilic interaction chromatography.In this study,a novel hydrophilic polymeric monolith was fabricated through photo-initiated copolymerization of 3-(3-vinyl-1-imidazolio)-l-propanesulfonate(SBVI)with pentaerythritol triacrylate using methanol and tetrahydrofuran as the porogenic system.Notably,the duration for the preparation of this novel monolith was as little as 5 min,which was significantly shorter than that required for previously reported sulfobetaine-based monoliths prepared via conventional thermally initiated copolymerization.Moreover,these monoliths showed good morphology,permeability,porosity(62.4％),mechanical strength(over 15 MPa),column efficiency(51,230 plates/m),and reproducibility(relative standard deviations for all analytes were lower than 4.6％).Mechanistic studies indicated that strong hydrophilic and negative electrostatic interactions might be responsible for the retention of polar analytes on the zwitterionic SBVI-based monolith.In particular,the resulting monolith exhibited good anti-protein adhesion ability and low nonspecific protein adsorption.These excellent features seem to favor its application in bioanalysis.Therefore,the novel zwitterionic sulfobetaine-based monolith was successfully employed for the highly selective separation of small bioactive compounds and the efficient enrichment of N-glycopeptides from complex samples.In this study,we prepared a novel zwitterionic sulfobetaine-based monolith with good performance and developed a simpler and faster method for preparation of zwitterionic monoliths.
ABSTRACT
SUMMARY Pheochromocytomaisrareinpregn’ancy.Clinicalfeaturesofacaseofpheochromocytoma during pregnancy in the Peking University People’s Hospital was investigated and the literature reviewed to discuss the diagnosis and treatment of this disease.The patient manifested with hypertension and pro-teinuria,who was easily misdiagnosed with gestational hypertension disease.When she was transferred to our hospital,the symptoms such as,paroxysmal palpitation,dizziness,vomiting were noticed,and the possibility of pheochromocytoma was considered due to the accompanying abdominal mass.An emergent cesarean section was performed successfully due to preterm labor during the treatment of the disease.Af-ter the delivery the drug preparation continued.And the laparoscopic resection of pheochromocytoma pro-ceeded when the blood pressure was steady.The patient recovered fully after the surgery.The final diag-nosis of pheochromocytoma was confirmed with the pathology.Its diagnosis and treatment experiences could improve our understanding and treatment of secondary hypertension due to pheochromocytoma in pregnancy.
ABSTRACT
Objective Assisted reproductive technology ( ART) is associated with an increased incidence of offspring de-fects.The aim of this study was to investigate the impact of embryo vitrification in in vitro fertilization ( IVF) on the growth and devel-opment of the offspring by comparing the development status of mouse offspring from fresh embryo versus vitrified embryo transplanta-tion. Methods This study included three groups of mouse offspring , from natural fertilization ( n=12 ) , fresh embryo transplanta-tion (FET, n=9), and vitrified embryo transplantation (VET, n=9).We compared the body weight and body fat content in the sex-ually mature stage among the three groups of mice . Results No obvious differences were found in the morphology of the embryos be-tween the FET and VET groups .The body weight of the mouse offspring was significantly higher in the VET than in the natural control group at 0 postnatal (PN) week (P<0.01) and 12 PN weeks (P<0.01), and so was it in the FET group than in the control at 0 PN week (P<0.01) and 6 PN weeks (P<0.05).The body fat content at sexual maturity was remarkably higher in the VET than in the FET and control groups ([9.32 ±4.34] vs [5.24 ±2.56] and [2.80 ± 0.48] g, P<0.05), and so was the muscle content in the VET than in the control ([33.77 ±4.22] vs [27.50 ±1.79] g, P<0.01). Conclusion In IVF, fresh embryo transplantation has less interference with the growth and development of mouse offspring than vitri-fied embryo transplantation .
ABSTRACT
Selective estrogen receptor modulators (SERMs) is a class of estrogen-like non-steroid compounds that are able to bind to steroid hormone receptors .They can act as estrogen receptor agonist or antagonist depending on the target tissue and hormonal environment .Additionally , SERMs play an antioxidant role by scavenging oxygen free redicals , inhibiting lipid peroxidation , adjusting the level of NO and NOS , inhibiting mitochondrial permeability transition , improving the metabolism of free fatty acids in the mitochon-drial and regulating non-genomic transcription pathway .

ABSTRACT
Objective To investigate the change of gamma-aminobutyric acid A (GABAA) receptor α1 subunit mRNA expression in nitroglycerin induced migraine rat model,thus suggesting the relationship between GABAA receptor and migraine.Methods Thirty adult female Sprague-Dawley (SD) rats were randomly divided into control group,migraine model group,sodium valproate-treated group,each of the last 2 groups was divided into the attacking group and intermission group.The model of migraine was established using Cristina method,once a week for 5 weeks.After the second injection,rats in sodium valproate-treated group were given sodium valproate(0.5 g/L,10 ml/kg) everyday,and those in control group and model group were given normal saline solution(10 ml/kg).After the fifth injection,at the second hour(attacking groups) or the fourth day(intermission groups and control group),reverse transcription-polymerase chain reaction was used to detect the expression level of GABAA receptor α1 mRNA in brainstem and trigeminal ganglion.Results The expression level of GABAA receptor α1 mRNA in modeling attacking group(1.50 ±0.13) was higher than any other group(control group:1.01 ±0.24,modeling intermission group:1.04 ±0.10,sodium valproate-treated attacking group:0.99 ± 0.22,sodium valproate-treated intermission group:0.72 ± 0.03),and it was significantly higher than modeling intermission group(x2 =9.490,P =0.009).There was no statistical difference between modeling group and any other group,and compared with control group,there was no statistical difference in sodium valproate-treated attacking group or intermission group.Conclusion The pathogenesis of migraine may be related to the expression level of GABAA receptor α1 mRNA.
ABSTRACT
Objective To evaluate the efficacy and tolerability of the combination of oxaliplatin,ifosfamide and epirubicin(IAP)in treatment of recurrent or platinum-resistant ovarian cancer patients.Methods A total of 25 patients received the combined chemotherapy of ifosfamide(3-4 g/m2),epirubicin(50-60 mg/m2)and oxaliplatin(130 mg/m2).The cycles were repeated every 21 days.The efficacy and toxicity were evaluated in 21 patients who received more than 2 cycles of IAP chemotherapy.Results The overall response rate was 71%,with a complete response in 10(48%),partial response in 5(24%),stable disease in one(5%),and disease progression in 5(24%).The median progression-free and overall survival time were 11(1 to 33)months and 31(1 to 71)months.While overall response rate was 60%in 10 patients with primary platinum resistant,and 88%in 8 patients with secondary platinumresistant.Grade Ⅲ-Ⅳ myelosuppression rate wss 30%.The most common non-hematologic toxicity was perineurotoxicity(38%).Conclusions The combination of oxaliplatin,ifasfamide and epirubicin appears to be effective for recurrent or platinum-resistant ovarian cancer patients as salvage chemotherapy and the toxicity is also tolerable.However,it needs to be evaluated by multiple clinical trials.
