The processing technology of traditional Mongolian medicine materials is distinctive, and it is one of the main characteristics of Mongolian pharmacy. Most of Mongolian medicines were used in the raw, but a quarter of medicinal materials need to be produced. Since ancient times, the processing of Mongolian medicine have cooperated with the Mongolian medicine clinical, which plays an important role in improving curative effect of Mongolian medicine and ensuring the safety of the drug. At present, the Mongolian medicines are processed still according to the traditional methods of the ancient literature method which has a lot of problems such as lag in technology, method of diversification, ambiguous indicators and unclear mechanism. Standardization of Mongolian medicine processing was based on traditional Mongolian medicine basic theory, which both projecting the characteristic, inheriting the traditional colleagues and reference to modern medicine, pharmacology, toxicology and other disciplines of knowledge. In this article, the processing situation, existing problem and standardization research of Mongolian medicine were described that providing a reference for the modernization and standardization of Mongolian medicine.

Objective To determine the treatment outcome and prognosis after resection of esophageal cancer.Methods 312 patients who developed recurrence after curative resection for squamous cell cancer of the thoracic esophagus were analyzed retrospectively.Results Recurrence was found after a mean period of 17.8 months(range 2～56 months).Recurrence pattern was catagorized into lymphatic,hematogerous,mixed and anastomotic.The number of patients in each recurrence group was 188,42,60,22.312 patients were enveloped into a noadjuant treatment group(NT,68),a radiotherapy alone group(RT,110),a chemotherapt group(CT,72) and a radiotherapy combined chemothepapy(CRT+CT,32).The 0.5-,1-,2-and 3-year overall survival rates for NT were 63.5%,35.2%,16.3% and 13.1%;For CT were 65.7%,52.3%,11.9% and 9.2%;For RT were 75.6%,49.2%,32.2% and 14.2%,respectively.Compared with CT there were significant differences in survival for patients receiving RT alone or combined with CT(P0.05).Multivariate analysis showed that depth of tumor invasion,lymph node metastasis,operative procedure and different regimens of therapy were significant prognostic factors.Conclusion Esophagectomy with cervical anastomasis is recommened for esophageal carcinoma,additional cervical lymphadenectomy is benefical in a few patients.Radiotherapy or combined with chemotherapy to be effective in prolonging the survival of patietns with recurrenes after esophageal resection for cancer.Investigation for more effective drugs and regimens of chemotherapy need to be taken.

Objective To analyze the etiology of diabetes ketoacidosis(DKA) in children with type 1 diabetes.Methods Totally 850 person-time of type 1 diabetes children in recent 20 years in our hospital were selected as studied subjects. Two hundred and twenty-five person-time of them were hospitalized because of DKA.Fifty-six cases (131 person-time) were due to recurrent DKA.These patients were classified into 2 groups according to onset time: group 1(diagnosed from 1982 to 1991) and group 2(diagnosed from 1992 to 2001).Results The analysis of recurrent DKA suggested that 71.8 % of them was due to infection, 20.4 % of them did not obey diabetic diet and 9.2 % of them discontinued insulin injection. The etiology of DKA showed no difference in two groups. The number of recurrent DKA in two groups was significantly different (P

Objective To evaluate the associations of human leukocyte antigen(HLA)-DQ gene with autoimmune polyglandular syndrome(APS),type 1 diabetic mellitus(T1DM) and autoimmune thyroid disease(AITD).Methods Fifteen cases of APS,29 cases of T1DM and 40 cases of AITD were selected as research subjects,while 27 healthy children were selected as controls.The DQA1 and DQB1 alleles were determined by polymerase chain reaction(PCR) and sequence-based typing method.The difference of their frequency in children and adolescents was analyzed.Results Compared with controls,APS and T1DM patients had increased frequency of subjects with DQA1*0301,0501(all P

AIM: To investigate the contraction effect of essential oil of Radix Angelicae Sinensis on isolated uterus in rats. METHODS: Isolated uterine strips of rats were used to observe the reactions in the presence of oxytocine and high k + depolarization solution. RESULTS: The isolated rat uterus contraction induced by oxytocin and Ca 2+ after high K + depolarization was dose dependently inhibited by the essential oil. The cumulative dose response curves of CaCl 2 shifted to right and the maximal responses were depressed. This showed that the essential oil was a non competitive antagonist. The extracellular and intracellular Ca 2+ dependent contraction evoked by oxytocin could also be inhibited by the essential oil. CONCLUSION: The essential oil of Radix Angelicae Sinensis could inhibit the contractility of the isolated uteri, and it might act as an Ca 2+ antagonist to relax the isolated rat uterus.

AIM To investigate whether ATP sensitive pota ss ium channels are involved in the protective effects of ischemic preconditioning on spinal cord in rabbits. METHODS Twenty seven male New Zealands white rabbits were randomly assigned to 3 groups (9 in each group):ischemia gro up(IC)、ischemic preconditioning group (IPC) and glibenclamide + ischemic precon ditioning group(G+I). In IC group, spinal cord ischemia was induced by an infrar enal aorta clamping for 20 min; IPC group underwent a 6 min ischemic preconditio ning followed by 30 min of reperfusion before the 20 min clamping; G+I group wer e administered glibenclamide (an ATP sensitive potassium channel blocker, 2 mg? kg -1 )intravenously 20 min before the ischemic preconditioning. Neurologic function was scored at 8,12,24 and 48 h after reperfusion. All animals were sa crificed at 48 h after reperfusion and the spinal cords (L 5～7 ) were remov ed for histopathologic study. RESULTS The neurologic function sco res in IPC group at each observe interval were higher than those in IC group and G+I group (P

AIM: To evaluate the protective effect of rapid phase of ischemic preconditioning against spinal cord ischemic injury in rabbits. METHODS: Thirty six male New Zealands white rabbits were randomly assigned to 3 groups (12 in each group): ischemia and reperfusion injury group (IR group), ischemic preconditioning + IR group (IPC+IR group) and sham operation group (sham). In IR group, spinal cord ischemia was induced by an infrarenal aorta clamping for 20 min; The rabbits in IPC+IR group underwent a 6 min ischemic preconditioning followed by 30 min of reperfusion before the 20 min clamping; The rabbits in sham group underwent the same procedures as the IR group except for infrarental aortic unclamping. Neurologic status was scored at 8, 12, 24 and 48 h after reperfusion. All animals were sacrificed at 48 h after reperfusion and the spinal cords (L_(5-7)) were removed for histopathologic study and determination of the activity of Na~+, K~+-ATPase. RESULTS: The neurologic function scores in sham group and IPC+IR group at each observation interval were higher than those in IR group (P

AIM: To study the apoptotic role of wild-type p53 in induction of plaque instability in atherosclerotic rabbits. METHODS: Fifty-four New Zealand White rabbits underwent balloon-induced abdominal aortic wall injury and then were fed on a diet of 1% cholesterol. At the end of the eighth week, the rabbits were randomly divided into two groups: group A and group B. Recombinant adenovirus carrying p53 and ?-galactosidase (LacZ) genes were injected in group A and B, respectively. Two weeks later, 10 rabbits each in group A and B was killed and the remaining rabbits all underwent pharmacological triggering with injection of Chinese Russell's viper venom and histamine. RESULTS: Compared with group B, p53 gene over-expression in group A resulted in a marked increase in number of positive apoptotic cells (2.5%?0.8% vs 1.0%?0.3%, P

Objective There have been a few reports on chronically recurrent and generalized superficial mycosis caused by trichophyton rubrum.This article was to investigate the cause, diagnosis and therapy of the mycosis. Methods 5 patients with chron-ically recurrent and generalized superficial mycosis caused by trichophyton rubrum were collected from June 2012 to June 2014 in our hospital.Bacterioscopic examination and cultivation were made on skin lesions of the patients.A typical patient who had 7-year course of desease with toenails seriously infected and widespread skin eruption was selected for histopathology examination on skin lesions, mi-crobiology and molecular biology study on 4 bacterial strains isolated from skin lesions in different parts, and in vitro chemosensitivity assay for drug selection.PCR (rDNA ITS sequence analysis) was performed for diagnosis and early treatment. Results Microscopic examintion on skin lesions demonstrated numerous septate, branched hyphae.Cultivation and molecular biology study identified tricho-phyton rubrum.The strain was identified as trichophyton rubrum by ITS sequence analysis and the isolated strains from different lesions were the same fungal species.Histopathology examination revealed slight hyperplasia of squamous epithelium , epidermal hyperkeratini-zation and the upper dermis presented a sparse perivascular lymphocytic infiltrate.The PAS-stain confirmed the presence of few hyphae in the horny layer.The pathogen of this case was trichophyton rubrum. A combination therapy with systemic itraconazole and topically applied terbinafine hydrochloride cream was successful.A follow-up examina-tion one year later showed no recurrence of symptoms. Conclusion The isolation and identification of pathogen is the key to the diagnosis of chronically recurrent and generalized superficial mycosis, with ad-ditional attention to all or none toenail infection.The therapy should not focus simply on the tinea corporis, while comprehensive treatment combined with chemosensitivity assay is preferred.
