Objective To evaluate the protective effect of Fangyouling extracted from herb on Schistosoma japonicum in-fection in the field. Methods The residents in 2 villages Zhaonao Village and Miaochang Village were divided into Group A 139 persons and Group B 162 persons and the residents in Group A embrocated Fangyouling before their contacting the in-fested water and the residents in Group B did not. All the residents were investigated with questionnaires and received the blood and stool examinations for schistosomiasis. Results The positive rates of blood tests were 3.13%and 9.34%in Group A and Group B respectively, the positive rates of stool examinations were 1.92%and 6.44%in Group A and Group B respectively both P values<0.05 . Conclusion Fangyouling has a good protective effect on S. japonicum infection.

The effects of tetrandrine (Tet) on blood pressure, plasma renin activity (PRA) and the contractility of the papillary mascle and portal vein were studied in rats. After 4 d administration of Tet 30 mg/kg, 2/d, ig, blood pressure was decreased markedly in anesthetized male SD rats, but there were no effects on heart rate and PRA. A single dose of Tet 15 mg/kg iv reduced blood pressure and heart rate significantly, while did not change PRA. This single dose produced similar hypotensive effect in rats with and without pretreatment of Tet 30 mg/kg, 2/d, 4d, indicating the absence of tolerance. Tet inhibited the paced papillary muscle contractility and the spontaneous portal vein contractility, and the EC50 were 5.33?10-6mol/L and 4.25?10-5 mol/L, respectively. So the vascular selectivity of Tet is 0.12.

Objective To investigate the feasibility of evaluating the pancreatic fat deposition with ultrasound,and analyze the relationship of pancreatic fat deposition with the risk factors for diabetes.Methods Two hundred and ninety-four subjects were recruited in the diabetes epidemic survey of Shanghai Sixth Peoples' Hospital,Shanghai Jiaotong University from Oct 2015 to Jan 2016,including 111 diabetes mellitus (DM) cases,54 sugar metabolic abnormalities (IGR) cases,and 129 healthy cases as control group.The general data were collected.Biochemical indicators including ALT,AST and insulin in fasting blood samples were detected,and insulin resistance index (HOMA2-IR) and insulin secretion index (HOMA-IS) were calculated.The pancreatic fat deposition was evaluated by the ultrasound,and pancreas echoes were divided into three levels (1,2,3),by comparing with the echo of the rectus.The Chi-square test was used to analyze the pancreatic fat deposition rate,while the Logistic regression was used to figure out the diabetes high-risk factors influencing the pancreatic fat deposition.Results Forty-two subjects were found to have the pancreatic fat deposition in the healthy group (33.3％),of whom 19 cases,16 cases and 8 cases were categorized into level 1,2 and 3,respectively.Thirty subjects were found to have the pancreatic fat deposition in the IGR group (55.6％),of whom 14 cases,11 cases and 5 cases were categorized into level 1,2 and 3,respectively.Sixty-seven subjects were found to have the pancreatic fat deposition in the DM group (60.4％),of whom 37 cases,18 cases and 12 cases,were categorized into level 1,2,3,respectively.The pancreatic fat deposition rates of the 3 groups were statistically significantly different (P＜0.01).Multivariate Logistic regression analysis showed that body mass index (BMI),HOMA2-IR,high triglycerides (TG),and total cholesterol (TC) may be the-risk factors for the pancreatic fat deposition in IGR and T2DM patients.Conclusions The ultrasound evaluation on pancreatic fat deposition was feasible,and the pancreatic fat deposition was related to multiple high-risk factors for diabetes.

Tyrosine-3-monooxy genase/tryptophane-5-monooxy-genase activator protein ( 14-3-3 protein ) is a family of highly conservative and widely expressed acidic polypeptides in all eukaryotic cells. The 14-3-3 protein family consists of adaptors and scaffolds that participates in many cellular processes, such as apoptosis and metabolism. Recent studies have found that 14-3-3 protein is associated with many proteins related to lipid metabolism. It could be exploited for therapy of lipid metabolism disorders. This paper briefly describes the role of the 14-3-3 protein in the lipid metabolism and its related diseases.

Hypercalcemia is an abnormal calcium metabolism, which can be caused by many diseases. Hypercalcemia caused by sarcoidosis is unusual. Sarcoidosis is a systemic granulomatous disease, it is lack of specificity in initial manifestations and easy to be misdiagnosed. In this paper, we report a patient with hypercalcemia and mediastinal lymphadenectasis, which the first diagnosis was misdiagnosed as tumour. Finally, sarcoidosis was diagnosed by mediastinal lymph node biopsy, and the patient was subsequently treated with glucocorticoid. Prednisone treatment improved symptoms of sarcoidosis, normalised serum calcium and mediastinal lymph nodes were diminished. This case suggests that clinicians need to raise awareness of sarcoidosis to identify and diagnose it correctly.

Objective Evaluation of the efficacy of high-frequency repetitive transcranial magnetic stimulation for chronic disturbance of consciousness after severe craniocerebral injury based on magnetic resonance spectroscopy.Methods The clinical data of 106 patients with chronic disturbance of consciousness after severe craniocerebral injury from January 2018 to December 2022 were retrospectively analyzed,and they were divided into control group(conventional rehabilitation treatment)and observation group(high frequency repetitive transcranial magnetic stimulation treatment)by propensity score matching method(1∶1),with 53 cases in each group.Both groups were examined by magnetic resonance spectroscopy(MRS)before and after treatment.The brain metabolic indexes[N-acetyl aspartate(NAA)/creatine(Cr)value,choline complex(Cho)/Cr value],Glasgow coma scale(GCS)score,electroencephalogram(EEG)grading,coma recovery scale(CRS-R)score,brainstem auditory evoked potential(BAEP)grading,upper limb sensory evoked potential(SSEP)grading and Cerebral blood flow perfusion index[cerebral blood volume(CBV),mean transit time(MTT),cerebral blood flow(CBF)]were compared between the two groups.Results After treatment,the NAA/Cr values of the thalamus and brainstem in the two groups increased,while the Cho/Cr values decreased,and the levels of brain metabolic indexes in the observation group were signifi-cantly better than those in the control group(P<0.05).The two groups'GCS score and CRS-R score increased,and the improvement of the observation group was better than that of the control group(P<0.05).The BAEP grading,EEG grading,and SSEP grading of the two groups improved,and those of the observation group were better than the control group(P<0.05).The CBF and CBV of the two groups increased,and MTT decreased,and the level of cere-bral blood perfusion index in the observation group was better than that in the control group(P<0.05).Conclusion High frequency repetitive transcranial magnetic stimulation has a significant effect on the recovery of patients with chronic consciousness disorders after severe craniocerebral injury.The mechanism may be related to improving the blood flow velocity of brain tissue and metabolism in the brain.
