Protein tyrosine phosphatase (PTP) 1B is a potential target for the treatment of diabetes and obesity. We have previously identified the benzoyl sulfathiazole derivative II as a non-competitive PTP1B inhibitor with in vivo insulin sensitizing effects. Preliminary SAR study on this compound series has been carried out herein, and thirteen new compounds have been designed and synthesized. Among them, compound 10 exhibited potent inhibition against human recombinant PTP1B with the IC50 value of 3.97 micromol x L(-1), and is comparable to that of compound II.

A study was carried out in south of Vietnam 15 Patients with Plasmodium falciparum gametocytes and asexual parasites were distributed into groups A, B and C. Artesunate was given orally at a total dose of 600 mg for 5 days in group A, 200 mg for 2 days in group B and intravenously at a total dose of 360 mg for 5 days in group C respectively. Gametocytes count was done before medication and daily after medication. Meanwhile, Anopheles dirus as a vector was employed to study the infectivity of gametocyte, The result showed that the mean gametocyte clearance time in three groups were respectively 15.4?5.0, 20.6?4.8 and 20.3?4.0 days. The mosquitoes were not infected from the blood in 2, 5 and 5 of 5 patients respectively on days 7, 14 and 21 in group A; 1 and 5 of 5 patients on day 14 and 21 in group B; 2 of 5 patients and 3 of 3 patients on days 14 and 21 in group C. It indicates that artesunate has remarkable effect on Plasmodium falciparum gametocytemia and its infectivity to mosquitoes.

Objective To establish a rat model of post-traumatic stress disorder(PTSD)through single-prolonged stress(SPS)and to observe the effect of social isolation on the behavior of the SPS model rats. Methods A total of 36 rats were randomly divided into the normal group, SPS model group and SPS combined with social isolation group. The rats in both SPS model group and SPS combined with social isolation group were modeled by single-prolonged stress,and the rats in the SPS combined with social isolation group were raised separately after modelling. The weight gaining,the total movement distance in open field test,the frequency of grid crossing,the single maximum movement distance,and the freezing frequency and time durations in the freezing behavior test were measured after 7 days of modeling. Results Compared with the normal group,the weight gaining and the single maximum movement distance of the rats in the SPS model group were significantly decreased(P < 0.01),as well as the total movement distance and the frequency of grid crossing(P < 0.05),while the freezing frequency and time in the freezing behavior test were significantly increased(P < 0.01). Compared with the normal group,the weight gaining and crossing times of the rats in the SPS combined with social isolation group was decreased(P <0.05),and the freezing frequency and time durations in the freezing behavior test were increased(P < 0.05). In addition, compared with the SPS model group,the total movement distance in the open field test,the frequency of grid crossing and the single maximum movement distance of the rats in the SPS combined with social isolation group were increased(P < 0.05). Conclusions The rat model of post-traumatic stress disorder is successfully established by single-prolonged stress, and 7 days of social isolation may alleviate the anxiety state of SPS model rats.

Objective:To observe the effects of Xiaoqinglong Decoction and Tingli-Dazao-Xiefei Decoction in treating chronic heart failure with syndrome of cold phlegm obstructing lung. Methods:Eighty-six chronic heart failure patients from January of 2017 to December of 2018 in our hospital who met the inclusion criteria were selected and divided into 2 groups according to the random number table method with 43 patients in each group. The control group was treated with conventional therapy, and the observation group was orally treated with Xiaoqinglong Decoction and Tingli-Dazao-Xiefei Decoction. Both groups were treated for 3 months. Then scored the symptoms of cold phlegm obstructing lung from four aspects: palpitations, cough and asthma, uria and edema, and sputum. The ultrasonic cardiogram was used to detect the left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction (LVEF). The ELISA method was used to measure levels of vascular pseudohemophilia factor (vWF),endothelin-1 (ET-1) and serum levels of total antioxidant capacity (TAC), lipid peroxide (LPO), SOD, MDA. The efficacy was evaluated. Results:The total effective rate of the observation group was 90.7% (39/43), significantly higher than that of the control group as 69.8% (30/43), and the difference between the two groups was statistically significant ( χ2=4.692, P=0.030). After the treatment, scores of palpitation, cough and asthma, urine and sputum in the observation group were obviously lower than those of the control group ( t value were 7.621, 7.033, 6.831, 6.635, respectively, all Ps<0.01); the LVEDD (51.41 ± 5.69 mm vs. 58.49 ± 6.77 mm, t=9.809), LVESD (40.04 ± 4.48 mm vs. 43.25 ± 5.21 mm, t=6.776) of the observation group were significantly lower than that of the control group, and while LVEF (50.16% ± 5.89% vs. 45.87% ± 5.16%, t=7.761) was significantly higher than that of the control group ( P<0.01). Plasma levels of vWF (103.55% ± 11.98% vs. 138.11% ±15.71%, t=41.453) and ET-1 (67.05 ± 7.18 pg/ml vs. 81.72 ± 10.03 pg/ml, t=18.990) in the observation group were significantly lower than that of the control group ( P<0.01). The serum levels of TAC and SOD levels in the observation group were significantly higher ( t value were 4.662, 13.331, respectively, all Ps<0.01), while LPO and MDA levels were significantly lower than the control group ( t value were 4.982, 4.031, all Ps<0.01). Conclusions:The Xiaoqinglong Decoction and Tingli-Dazao-Xiefei Decoction in treating chronic heart failure can improve the heart function and symptoms with syndrome of cold phlegm obstructing lung, and increaseclinical efficacy.

Objective:To study the regulatory effect of miR-9 on the proliferation of breast cancer cells by targeting hexokinase 2 (HK2) .Methods:Breast cancer tissues and paracancer tissues were collected and the expression levels of miR-9 and HK2 were detected. MCF-7 cells were cultured and divided into blank control group, NC group, miR-9 group, NC-siRNA group and HK2-siRNA group. The cell viability, expression levels of HK2 and cleaved caspase-3 were detected, the targeted binding of miR-9 to HK2 was verifed.Results:the expression level of miR-9 in breast cancer was lower than that in paracancer tissue (0.52±0.08 vs 1.05±0.25, t=16.685, P<0.000) , and the expression level of HK2 was higher than that in paracancer tissue (0.73±0.14 vs 0.34±0.08, t=17.587, P<0.000) , and the expression level of miR-9 was negatively correlated with HK2; the OD490 level, the expression level of HK2 and the fluorescence activity of double luciferase reporter gene containing HK2 mRNA 3 'UTR in miR-9 group were lower than those in NC group (0.58±0.09 vs 1.04±0.21, 0.51±0.08 vs 1.18±0.24, 41.11±9.28 vs 148.28±29.59, t/P=4.027/0.007, 5.297/0.002, 6.912/0.001) , and the expression level of cleaved caspase-3 was higher than that in NC group (1.08±0.26 vs 0.42±0.09, t/P=4.797/0.003) . The OD490 level and the expression level of HK in HK-siRNA group were higher than that in NC-siRNA group, and the expression level of cleaved caspase-3 was higher than that of NC-siRNA group. Conclusion:miR-9 can inhibit the proliferation of breast cancer cells, and its mechanism may be related to the targeted inhibition of HK2 expression and the increase of downstream cleaved caspase-3 expression.

Objective:With the in-depth study of complement dysregulation,glomerulonephritis with dominant C3 has received increasing attention,with a variety of pathologic types and large differences in symptoms and prognosis between pathologic types.This study analyzes the clinical,pathological,and prognostic characteristics of different pathological types of glomerulonephritis with dominant C3,aiming to avoid misdiagnosis and missed diagnoses. Methods:The clinical,pathological,and follow-up data of 52 patients diagnosed as glomerulonephritis with dominant C3 by renal biopsy from June 2013 to October 2022 were retrospectively analyzed.According to the clinical feature and results of pathology,15 patients with post-infectious glomerulonephritis(PIGN)and 37 patients with of non-infectious glomerulonephritis(N-PIGN)were classified.N-PIGN subgroup analysis was performed,and 16 patients were assigned into a C3-alone-deposition group and 21 in a C3-dominant-deposition group,or 27 in a C3 glomerulopathy(C3G)group and 10 in a non-C3 nephropathy(N-C3G)group. Results:The PIGN group had lower creatinine values(84.60 μmol/L vs 179.62 μmol/L,P= 0.001),lower complement C3 values(0.36 g/L vs 0.74 g/L,P<0.001)at biopsy,and less severe pathological chronic lesions compared with the N-PIGN group.In the N-PIGN subgroup analysis,the C3-dominant-deposition group had higher creatinine values(235.30 μmol/L vs 106.70 μmol/L,P=0.004)and higher 24-hour urine protein values(4 025.62 mg vs 1 981.11 mg,P=0.037)than the C3-alone-deposition group.The prognosis of kidney in the PIGN group(P=0.049),the C3-alone-deposition group(P=0.017),and the C3G group(P=0.018)was better than that in the N-PIGN group,the C3-dominant-deposition group,and the N-C3G group,respectively. Conclusion:Glomerulonephritis with dominant C3 covers a variety of pathological types,and PIGN needs to be excluded before diagnosing C3G because of considerable overlap with atypical PIGN and C3G;in addition,the deposition of C1q complement under fluorescence microscope may indicate poor renal prognosis,and relevant diagnosis,treatment,and follow-up should be strengthened.
