OBJECTIVETo explore the therapeutic effect of diagnosis and treatment program of integrative medicine (IM) on level 2 hypertension in the young and middle-aged patients and their ambulatory blood pressure.

METHODSA randomized, placebo parallel and controlled, multi-center clinical trial was performed. Totally 199 young and middle-aged level 2 hypertension patients were randomly assigned to the treatment group (99 cases) and the control group (100 cases). All received combined hypotensive treatment program by taking Nifedipine Sustained Release Tablet and Hydrochlorothiazide as basic drugs. Patients in the treatment group additionally took Western medicine (WM) combined Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily), while those in the control group additionally took WM combined simulative agents of Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily). The treatment course was 8 weeks for all, and 24-week follow-ups performed. 24 h ambulatory blood pressure and casual blood pressure, and their efficacies were compared between the two groups, and safety assessed as well.

RESULTSCompared with before treatment in the same group, daytime and night casual blood pressure, as well as 24 h ambulatory blood pressure were all obviously improved in the two groups (P < 0.01). Average diastolic and systolic blood pressures at night decreased more in the treatment group than in the control group with statistical difference (P < 0.05). There was no statistical difference in total efficacies of daytime casual blood pressure or ambulatory blood pressure (P > 0.05).

CONCLUSIONJiangyabao serial drugs combined WM in treating young and middle-aged level 2 hypertension patients showed obvious effect in improving night blood pressure, especially for night diastolic blood pressure.

BACKGROUND: Embryonic pancreatic tissue is characterized by its abundance, potent in proliferation & differentiation, and minimal immunological rejection. It is widely considered as potential pancreatic endocrinological stem cells resource for treating diabetes mellitus.OBJECTIVE: To investigate the embryonic mouse pancreatic tissue isolation technique and observe the recipients' blood glucose regulatory effects of the grafted embryonic pancreas in an experimental diabetes mellitus mouse model.METHODS: Pancreatic tissue from C57B1/6 mouse embryos at embryonic days 11.5-16.5 was isolated under the stereomicroscope. C57BL/6 mouse models of streptozocin-induced diabetes mellitus were established and then randomly divided into two groups: transplantation group, in which, five pieces of pancreatic tissue of mice at embryonic 16.5 days were transplanted into mouse renal capsule, and sham-operated control group, in which, 0.05 mL RPMI1640 culture medium was injected into mouse renal capsule. When blood glucose level of the transplantation group mouse was≤ 11.2 mmol/L, the endocrine function of embryonic pancreatic tissue transplanted was detected by IPGTT and IPITT methods and then the transplanted graft was removed for observing the blood glucose relapse.RESULTS AND CONCLUSION: Nearly intact pancreatic tissue of mice at embryonic days 11.5-16.5 could be isolated through the use of stereomicroscope. Pancreatic tissue morphology and color of mice ≤ embryonic 12.5 days were difficultly distinguished from adjacent tissue and they could only be isolated carefully according to the relationship with adjacent organs. Pancreatic tissue of mice > embryonic 12.5 days exhibited initial endocrinological tissue morphology mimic white cauliflower. Histological and ELISA examinations showed that embryonic pancreatic tissue could express and secrete insulin and the insulin level was gradually increased with developmental time. Embryonic pancreatic tissue could grow beneath the recipient renal capsule. The insulin and glucagon expression in the post-transplantational pancreatic tissue graft was increased compared with prior to transplantation. These results suggest that pancreatic tissue is a potential stem cell resource for treating the diabetes mellitus.

Objective To discuss the diagnosis and surgical treatment of multiple endocrine neoplasia 1 (MEN1). Methods The clinical data of MEN1 from 1974 to 2005 were retrospectively analyzed. Results There were 17 cases of MEN1 in our group. Among them, 11 cases were from 4 families. MEN1 gene mutation was detected in 14 cases admitted after 1997. There were 11 cases of pHPT, 6 cases of insulinoma, 8 cases of pituitary adenoma, 6 cases of adrenal adenoma, 2 cases of thymic carcinoid and 2 cases of collagenoma. Two patients had respectively 4 glands involved, 3 patients had 3, 7 patients had 2 kinds of gland involved respectively. Four patients had only one kind of gland involved. A 12 year old girl had no clinical symptom and biochemical change. Six patients presented with nephrolithasis, 6 patients had impaired pancreatic endocrine function. Subtotal parathyroidectomy was performed in 4 patients of pHPT, and one patient received parathyroid adenoma enucleation. Insulinomas were enucleated in 4 patients. Two patients underwent thymus tumor extirpation. Conclusions MEN1 varies in symptoms, even those from the same family. Cermline mutation test helps establish diagnosis. Operations should be aiming at tumor resection as well as the improvement of life quality.

Objective To discuss the diagnosis and surgical treatment of multiple endocrine neoplasia 2 (MEN2). Methods The clinical data of 28 MEN2 cases from Jun 1997 to Jun 2006 were retrospectively analyzed. Results There were 25 cases of MEN2a and 3 cases of MEN2b. Among the patients of MEN2a, 23 patients were from 7 families with mutation of codon 634, exon 11 of RET, 3 patients of MEN2b had mutation of codon 918, exon 16 of RET and no family history. Twenty-two cases of MEN2a had thyroid masses with elevated calcitonin level, in which 17 were pathologically diagnosed as medullary thyroid carcinoma (MTC) ,12 patients had pheochromocytomas. Among them, 5 were of multiple foci and 2 were malignant. Five patients presented hyperparathyroidism and 3 patients were asymptomatic without biochemical alterations. Three MEN2b patients had MTC and mucosal ganglioneuromatosis with Marfanoid, one patient had bilateral pheochromocytoma. Total thyroidectomy with bilateral dissection of regional lymph nodes was performed in 12 patients of MEN2a, and nodule enucleations was done in other 5 patients followed by persistent elevated calcitonin level. Nine MEN2a patients underwent pheochromocytoma enucleation including bilateral adrenal resection in 3 cases. Three MEN2b patients underwent total thyroidectomy with bilateral lymph node dissection. Conclusions MTC is the most often complications of MEN2. Germline mutation test helps to make early diagnosis. Radical total thyroidectomy in young patients may prevent MTC.

Antimicrobial peptides are a class of small peptides with anti-extrogenous pathogen activities.They are derived from organism and possess antibacterial,antifungus,antiviruses and anticancer cell actions.In recent years,it’s found that some microbial pathogens are able to resist antimicrobial peptides.The constitutive and inducible mechanism of a pathogen resists a given peptide were reviewed in this paper.

Objective To explore the role of tissue inhibitor of metalloproteinase-1(TIMP-1) during renal senescence by using human TIMP-1 transgenic mice.Methods Renal histological changes of wild type mice and transgenic mice at the age of 3,12,24 months were observed by periodic acid-schiff(PAS)staining of paraffin sections.The numbers of F4/80 positive cells were detected by immunofluoreseence.The protein expressions of TIMP-1,TIMP-2,matrix metalloproteinase(MMP)-9,MMP-2,intercellular adhesion molecule-1(ICAM-1),transforming growth factor?1(TGF-?1),collagenⅢand collagenⅣwere detected by Western blot.The activities of gelatinases and TIMP-1 were examined by gelatin zymography and reverse zymography respectively.Results Focal renal fibrosis was found in two genotypes with aging.At the age of 24 months,compared with wild type,in kidneys of transgenic type,the expressions and activities of gelatinases were dowregulated (MMP-2:2.08?0.20 vs.3.39?0.43;MMP-9:4.02?0.82 vs.6.72?1.40,all P＜0.05);the expressions of collagenⅢ,collagenⅣ,ICAM-1,and TGF-?1 were upragulated(0.72+0.11 vs.0.57?0.09;0.84?0.13 vs.0.6?0.11,0.72?0.12 vs.0.53?0.07; 0.69?0.12 vs.0.45?0.09,all P＜0.05),and the numbers of F4/80 positive cells were increased (18.8?4.4 vs.12.7?3.6,P＜0.05)with the upregulated expression and activity of TIMP-1(1.10?0.18 vs.0.62?0.09;50.75?7.25 vs.20.64?3.50,P＜0.05).Conclusions TIMP-1 could promote age-related renal fibrosis through enhancing inflammation reaction by ICAM-1 upregulation.

Objective To study the film￣forming property of film￣forming materials in dragon blood ethanol solution, and provide the reference for screening of film￣forming materials for dragon blood plastics. Methods PVA124,PVA1788, PVP￣K30, EC, MC, PVB were chosen to study the film￣forming property of film￣forming materials based on solubility, formation time, and adhesion. Results PVA1788 and PVP￣K30 mixed in dragon blood ethanol solution in proportion of 4:1 showed good film￣forming property, and the membrane was smooth, uniform and easy to tear off.However, PVA124 and PVP￣K30 mixed in proportion of 4:1 precipitated in dragon blood ethanol solution.EC, MC and PVB were not easy to tear off the membrane. Conclusion PVA1788 and PVP￣K30 mixed in proportion of 4:1 and added with propylene glycol is the optimal choice of film￣forming material for dragon blood spray film.

Objective To evaluate the diagnosis and surgical treatment of parathyroid carcinoma (PTC). Methods Clinical data of 8 PTC cases were analyzed retrospectively. Results PTC accounted for 5. 7% of patients with primary hyperparathyroidism (PHPT) in our hospital. There were 4 men and 4 women. Male patients had younger mean onset age compared with female patients. The disease history of PTC was shorter than PHPT of benign causes. Six patients were admitted for acute hypercalcemia. Seven patients complained of palpable neck mass. Calcium level was 3.75?0.34 mmol/L,and PTH level was 1429.47?841.75 pg/ml. Frozen section established diagnosis in only one case. Four patients underwent radical en bloc resection. Other 4 cases received routine simple parathyroidectomy, 3 patients developed recurrence in 12 - 18 months postoperatively. Conclusions Acute hypercalcemia is common in PTC. Frozen biopsy diagnosis is not satisfactory. An initial en bloc resection of tumor and adjacent structures contributes most to the prognosis.
