In pregnant women,positive rate of thyroid peroxidase antibody(TPOAb) is approximately 3%~10%.It is still controversial whether thyroid antibody positive rate is higher in women undergoing artificial assistant reproductive technologies.TAI might have a negative effect on pregnant outcome,which has been proved in different groups of women.Intravenous immunoglobulin,thyroxin replacement therapy and selenium therapy have been used for TAI intervention.More evidence is needed to demonstrate mechanism and evaluate effect for each therapy.

Inheirted metabolic disodrers(IMD)involves in multiple substance dysbolism,which usually results in irreversible neurological lesions because of various categories and complicated clinical manifestations.In resent years,IMD became one of the hot spots in medical domain around the world,original diagnostic technique and management progressed unceasingly.This paper provides an overview of the traditio-nal detection and treatment about IMD,and reviews the new techniques such as gene analysis,gene chip,organ transplantation and enzyme replacement therapy at the same time.

Objective To investigate the efficacy and safety of autohemotherapy therapy in ASST positive chronic idiopathic ur‐ticaria .Methods One hundred and twenty cases of chronic idiopathic urticaria treated in our department from April ,2012 to Janu‐ary ,2013 were divided into treatment group and control group ,60 cases in each group .Patients in treatment group were given oral ioratadine (10 mg/d) ,supplemented by autohemotherapy ;patients in control group were only given oral ioratadine (10 mg/d) .Both of the two groups were treated with twelve weeks ,then observed the effectiveness and safety of two kinds of treatment .Results The effective rate of treatment group and control group were 68 .33% and 48 .33% respectively ,and there was significant difference between the two groups (P<0 .01) .Conclusion Autohemotherapy combined antihistamine was of high efficiency and safety in the treatment of ASST positive chronic idiopathic urticaria ,while the long‐term curative effect remains to be observed .

OBJECTIVE: To investigate the effects of Wenyang Huoxue Recipe (WRHXR), a compound traditional Chinese herbal medicine for warming yang and promoting blood flow, on the expression of angiopoietin mRNA in rats with chronic aristolochic acid nephropathy induced by Caulis Aristolochia Manshuriensis (CAM) decoction, and to explore the protection mechanism of WYHXR against kidney damage. METHODS: Twenty-eight male SD rats were randomly divided into normal control group, CAM group and WYHXR-treated group. Rats in the normal control group (n=8) and CAM group (n=10) were intragastrically administered with normal saline 10 ml/(kg.d) or CAM decoction 10 ml/(kg.d) respectively. Rats in the WYHXR-treated group (n=10) were intragastrically administered with WYHXR 30 g/(kg.d) and CAM decoction 10 ml/(kg.d). The expressions of Ang-l and Ang-2 mRNAs were detected by real-time reverse transcription polymerase chain reaction (RT-PCR) after 20-week treatment. RESULTS: Compared with the normal control group, the expression of Ang-l mRNA was significantly decreased, and the expression of Ang-2 mRNA was significantly increased in the CAM group (P<0.01). Compared with the CAM group, the expression of Ang-l mRNA was increased in the WYHXR-treated group (P<0.01). The expression of Ang-2 mRNA had no significant difference between the CAM group and the WYHXR-treated group (P>0.05). Renal pathology showed that renal damage in WYHXR-treated group was significantly reduced as compared with the CAM group. CONCLUSION: WYHXR can up-regulate the expression of Ang-l mRNA, which may be its action mechanism in protecting the kidneys.

With polyethylene glycol vitamin E succinate (TPGS) as the carrier materials, and berberine hydrochloride ( BER) as model drug, we formed berberine hydrochloride (BER) -loaded TPGS nanomicells (BER-PMs) using filming-rehydration method to improve its solubility and in vitro anti-tumor effect. The transmission electron microscope (TEM) was used to observe the particle appearance; particle detector was used to detect the diameter and Zeta potential; and ultracentrifugation was utilized to determine the encapsulation efficiency (EE) and drug-loading (DD); dynamic dialysis method was used to study the in vitro release behavior of BER-PMs, and the anti-tumor activity against MCF-7 cells was determined by MTT method. Results showed that the average particle size of BER-PMs was (12.45 ± 1.46) nm; particle size was uniform and spherical; drug loading and encapsulation efficiency were (5.7 ± 0.22)% and (95.67 ± 5.35)%, respectively. Zeta potential was (-1.12 ± 0.23) mV; release rate within 24 h was 37.20% and 41.14% respectively in pH 7.4 and pH 6.5 phosphate buffer in vitro; compared with BER, BER-PMs can significantly inhibit MCF-7 cell proliferation (P < 0.05), promote cell apoptosis and improve the anti-tumor activity of BER in vitro. Therefore, the formed berberine hydrochloride micelle can more effectively promote the apoptosis of MCF-7 cell, and improve the drug's in vitro anti-tumor effect.

Objective To provide the service for scientific innovation and competition in biomedical industry of Hunan Province and the reference for working out biomedical patent strategies.Methods The data of biomedical patents in Hunan Province were collected using the patentEX and processed by metrics.Results The application number of patents increased from year to year with a high expiry rate.The technology of biomedical patents has entered into its mature period and the application of patents was focused on several important IPC classifications.Conclusion Tra-ditional technologies play a main role in biomedical industry of Hunan Province, but Hunan Province is relatively backward in modern biological technologies.The application number of invented biomedical patents is rather large, but their overall academic level is rather low.The majority of biomedical industry enterprises lack of competition awareness.It is thus necessary to strengthen the development of modern biological technologies, improve the aca-demic level of biomedical patents, increase the competition awareness of biomedical industry enterprises, lay stress on cooperative development of biomedical patents and on support of biomedical industry enterprises.
