ABSTRACT
Objective:To investigate the clinical efficacy and mechanism of Ganoderma lucidum hypoglycemic formula in the treatment of insulin resistance in patients with type 2 diabetes mellitus (T2DM) with liver and kidney yin deficiency. Methods:A total of 86 patients with T2DM with liver and kidney yin deficiency who were diagnosed and treated at Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine from January 2021 to February 2022 were included in this study. These patients were divided into a control group and a treatment group, with 43 patients in each group using a 1:1 ratio using the sealed envelope method. Both groups were treated with standardized Western medicine. The treatment group was also treated with the Ganoderma lucidum hypoglycemic formula. All patients were followed up for 12 weeks. The clinical symptoms, curative effect, glucose and lipid metabolism, inflammatory factors, oxidative stress change, and safety were compared between the two groups. Results:The total response rate in the treatment group was 88.4% (38/43), which was significantly higher than 53.5% (23/43) in the control group ( χ2 = 12.69, P < 0.001). After treatment, the traditional Chinese medicine syndrome score, fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin, insulin resistance index, total cholesterol, triglyceride, tumor necrosis factor α, and interleukin-6 decreased in each group. The amplitudes of decrease of the above indexes were greater in the treatment group compared with the control group (all P < 0.05). C-peptide in the fasting state, C-peptide at 2 hours after a diet, and superoxide dismutase increased in each group. The amplitudes of increase of the three indexes were greater in the treatment group compared with the control group (all P < 0.05). Conclusion:Ganoderma lucidum hypoglycemic formula can greatly improve insulin resistance and glucose and lipid metabolism in T2DM patients with liver and kidney yin deficiency. The underlying mechanism may be to further reduce the inflammatory response and anti-oxidative stress by down-regulating tumor necrosis factor α and interleukin-6 levels and up-regulating superoxide dismutase level, thereby effectively alleviating insulin resistance in T2DM.
ABSTRACT
Objective To study the effect of thrombin on proliferation and invasion of esophageal cancer cell line Eca109, and to explore its possible mechanism. Methods The proliferation and invasion of Eca 109 cells treated with thrombin were detected by MTT and Transwell assay, respectively. The activity of matrix metalloproteinase 2 (MMP-2) and MMP-9 in the supernatant of Eca109 cells was detected by gelatin zymography. Reverse transcription polymerase chain reaction (PCR) and immunocytochemistry were used to study the mRNA expression of protease-activated receptor 1 (PAR-1), the important receptor of thrombin, and subcellular localization of PAR-1 protein in Eca109 cells, respectively. Results Thrombin could promote Eca109 cells proliferation in a dose-dependent manner. Cell proliferative rates of 0.5 U/ml and 1.0 U/ml thrombin were 34.38 % and 57.19 %, respectively (P< 0.05). Compared to that of control group, the number of Eca109 cells incubated with 1.0 U/ml thrombin invading through the basement membrane of Transwell was increased (303.33 ±6.66 vs. 116.33 ±11.51, P< 0.05). When treated with various concentrations of thrombin for 24 h, the activities of MMP-2 and MMP-9, especially MMP-9, in the supernatant of Eca109 cells were increased in a dose-dependent manner. Eca109 cells expressed PAR-1 mRNA, and PAR-1 protein was mainly located on the cellular membrane. Conclusion Thrombin increases proliferation and invasion of esophageal cancer Eca109 cells and enhances the activities of MMP-2 and MMP-9 in cells supernatant, which might be induced by activation of PAR-1 located on cellular membrane.

Objective To explore the efficacy and safety of methotrexate combined with hysteroscopic in treatment of cervical pregnan-cy. Methods The data of 14 patients with cervical pregnancy were analyzed retrospectively. Results All patients were given combination therapy of mifepristone and methotrexate firstly,and they were discharged after bloodβ-HCG logarithmically decreased for further observation. Hysteroscopic surgery were applied whenβ-HCG level decreased to 100 mIU/mL. Conservative treatment received success in all 14 cases. It required 14~35 days,averagely (26. 5 ± 2. 7) days, methotrexate dosage of 50~150 mg,averagely (75. 5 ± 15. 0) mg, and mifepristone of volume 150~450 mg,averagely (275. 0 ± 54. 5) mg to make the bloodβ-HCG level decreased to 100 mIU/mL. The bleeding volume during hysteroscopy surgery was 5~50 mL,an average of (35. 6 ± 5. 2)mL. Conclusion Methotrexate combined with hysteroscopy is safe and fea-sible for treatment of cervical pregnancy.
ABSTRACT
Objective To investigate the application value of identification of the scalp surface locations of cerebral ischemia lesions before direct revascularization for moyamoya disease and to design surgical approaches according to this by using the fusion of single photon emission computed tomography ( SPECT) cerebral perfusion imaging with CT imaging. Methods The clinical data of 13 adult patients with ischemic-type moyamoya disease underwent superficial temporal artery-middle cerebral artery bypass surgery were analyzed retrospectively. SPECT cerebral perfusion imaging was fused with CT imaging of the same machine before procedure. The lesions of ischemia were located on the cortical surface. The surgical approaches were designed at the center of the ischemic lesions. The patients were followed up for 6 to 12 months after procedure. The improvement of clinical symptoms and cerebral perfusion of the patients were observed after operation. Results One patient had perioperative cerebral hyperperfusion syndrome,and the others did not have any perioperative complications. At one-month follow-up, the improvement of symptoms in 4 patients were excellent,in 5 were good,in 4 were fair,and none was poor. At 6 to 12 month follow-up,the improvement of symptoms in 9 patients were excellent,in 4 were good,and none was poor. The postoperative visual SPECT cerebral perfusion imaging analysis suggested that the cerebral perfusion was improved significantly as compared with before procedure in all patients. Quantitative analysis:There was significant difference in target ischemic lesions between preoperative Fb and postoperative Fb ([2. 13±1. 06]% vs. [4. 13±2. 09]%;P50%) , which indicated that the efficacy of the procedure was remarkable. The superficial temporal arteries fed to brain of the patients were observed after procedure by using the head CT angiography. The postoperative head MRI reexamination showed no new infarcts occurred at 6 months. Conclusion Combine SPECT cerebral perfusion imaging with CT imaging to design surgical approach for superficial temporal artery-middle cerebral artery bypass surgery may improve the efficacy and reduce the risks of operation.
ABSTRACT
Objective To examine the frequency of coexisting endometrial carcinoma with preoperative diagnosis of endometrial atypical hyperplasia (EAH).Methods From Apr 2002 to Apr 2007,61 consecutive patients diagnosed as EAH who underwent total hysterectomy in our department were retrospectively analyzed.Patients were stratified as 44 premenopausal cases and 17 menopausal cases.The patients were divided into 2 groups depending on whether or not cancer cells were found by histology in removed uterus (cancer group vs EAH group) to explore valuable predictive risk factors for concomitant endometrial carcinoma through reviewing the clinical data.Logistic regression analysis and logistic regression equation are used to evaluate the risk of coexisting endometrial carcinoma with preoperative diagnosis of endometrial atypical hyperplasia.Results Endometrial thickness and the type of EAH were selected into the equation in premenopausal cases,showing statistically significant differences(P ＜ 0.001) and the overall accuracy was 86.4％.Menopausal years and the type of EAH were selected into the equation in menopausal women,also showing statistically significant differences (P ＜ 0.04)and the overall accuracy was 82.4％.Conclusions Endometrial thickness and the type of EAH are valuable in predicting the risk of endometrial carcinoma in premenopausal women.Menopausal years and the type of EIN are valuable in prediciting the risk of coexistance with endometrial carcinoma in menopausal women.
ABSTRACT
Microalbuminuria (MAU) is a key component of metabolic syndrome (MetS) and is an early sign of diabetic nephropathy as well. Although routine Western medicine treatments are given to MetS patients to control high blood pressure, hyperglycemia and dyslipidemia, some patients still experience progressive renal lesions and it is necessary to modify and improve the treatment strategy for MetS patients.
