Objective To investigate the efficacy of acupoint injection of Astragalus on contents of SOD,HYP and MDA in skin of aging mice in-duced by D-galactose. Methods The mice were randomly divided into normal group,model group,Astragalus group,and saline group(n=15). Except for the normal control group,the mice of other groups were treated with continuous subcutaneous injection of D-galactose to establish mice ag-ing model. The Astragalus group mice was injected with 0.01mL Astragalus in Sanzuli acupoint per day,The saline group mice received an injection of same amount of saline. SOD,HYP and MDA changes in the skin tissue and serum were evaluated after 21 days. Results All the index in the skin tissue and serum showed significant difference(P<0.01)between model group mice and normal control group. Compared with model group,SOD activity and MDA content in the skin tissue and serum of the Astragalus group mice were significantly raised,HYP content was significantly reduced (P<0.01). There also were significant differences of these index between the saline group mice and the model group(P<0.05),but the effect was not as good as the Astragalus group mice. Conclusion Acupoint Injection of Astragalus can prevent and protect against skin aging induced by D-galactose.

Objective There is a significant increase of squamous cell carcinoma antigen ( SCCA) in patients with common skin diseases .The aim of this study was to investigate the difference expression of serum SCCA in patients with common skin diseases . Methods A total of 497 patients with 14 kinds of common skin diseases from the Department of Dermatology were recruited , and the serum SCCA was measured . Results The positive rates of SCCA in 116 patients with psoriasis and 37 patients with erythroderma were 90 .5% and 100%, respectively .The common skin diseases with positive rate of SCCA greater than 60% includes eczema (61.7%), generalized dermatitis (65.1%),pemphigus (61.1%), bullous pemphigoid (62.2%).The SCCA values in pustulosa (1.76 ±1.22 ng/mL) and arthropathica psoriasis (1.69 ±1.05 ng/mL) were decreased compared with pustular (2.86 ±1.46 ng/mL) and arthropathica psoriasis (3.56 ±1.84 ng/mL) (P<0.05). Conclusion The SCCA value may have a relationship with the increase of the performance of keratinization and desquamation in the skin diseases , and it could be used as a valuable indicator for the diagnosis and treatment in patients with cutaneous diseases .

Transient receptor potential vanilloid 1 (TRPV1) is a non-selective cation channel,which can be activated by multiple pathways during the course of the diseases.Recent studies indicate that primary sensory neurons of the pancreas express TRPV1 receptor and the activation of TRPV1 receptor promotes pancreatic inflammation.Moreover,blockade of these transient receptor potential channels can greatly ameliorate the pain response in experimental pancreatitis.

Objective To evaluate the effects of Botulinum-A toxin (BTX-A) injection into detrusor to treat detrusor hyperreflexia and neurogenic incontinence in the patients with spinal cord injury (SCI). Methods A total of 31 patients with SCI(mean age,30 years;male 20,female 11) were included into the study.All the patients underwent urodynamic examination and voiding diary was recorded.300 U of BTX-A was dissolved in 15 ml of saline,and the solution of BTX-A was injected into 30 different points in detrusor using a flexible cystoscopic needle.The evaluation for the effects and follow-up included voiding diary,urodynamic testing and observation of adverse and toxic effects. Results After the first injection,29 of the 31 patients had symptom relief within 3 to 14 days;4 cases received the second injection;4 cases were treated in combination with anticholinergic medication;and 2 cases had no improvement and,therefore,received other treatments.The mean follow-up was 8.5 months. After 3-week treatment of BTX-A,the mean frequency of incontinence decreased from 14.2 to 2.5 times per day.The mean volume of intermittent catheterization (IC) increased from 124 to 495 ml each time.Urodynamic data showed that mean cystometric bladder storage volume increased from 133 to 475 ml,mean maximum storage detrusor pressure decreased from 62.7 to 17.1 cmH 2O(1 cmH 2O=0.098 kPa).No adverse and toxic effect was observed. Conclusions Our initial experience suggests that Botulinum-A toxin injection into detrusor to treat detrusor hyperreflexia and neurogenic incontinence in patients with SCI may be an effective,safe,feasible and micro-invasive treatment choice.However,it is necessary to observe its long term outcome.

Objective To study the relationship between different serum markers model for patients with HBV infection and content of HBV-DNA,to provide evidence of diagnosis,treatment and provention of hepatitis B.Methods Determinations of HBV serum markers and HBV-DNA content by ELISA and real time fluorometric quantitative-PCR technique respectively in 814 sera samples.Results HBV-DNA positive rate was 87 28%(302 of 346 coses) in HBsAg(+),HBeAg(+),HBcAb(+) model.HBV copy quantity ≥10 8/ml accounted for 63 87%.HBV-DNA positive rate was 48 778%(40 of 82 cases) in HBcAb positive model HBV-DNA copy quantity in the partial samples was higher,it can occure in gene mutation of HBV precore regions,resulting in the experssion of HBeAg was failed,but virus replication was not influenced.The HBV-DNA positive rate and copy quantity in HBeAg(+) model was obviously high than those of other different serum markers model.Conclusion Serum marker model only applied to judg the degree of HBV replication and its infectivity were considerable diffecult,HBV-DNA quantitative determination could real reflect HBV replication condition,provede objective evidences of diagnosis,prevention and treatment of HBC hepatitis.

Objective To observe the changes of serumγ?glutamyl transpeptidase(GGT)levels before and after the patho?gen treatment in patients with subclinical schistosomiasis,and explore its clinical value in the diagnosis and treatment of sub?clinical schistosomiasis. Methods Totally 109 patients with subclinical schistosomiasis,who were found in the endemic inves?tigation of schistosomiasis in Ezhou City,were selected as the investigation subjects,and then they were treated with praziquan?tel. The serum GGT levels of the subjects before and after the treatment were detected and compared. Results Before the treat?ment,the average value of the GGT levels of the 109 patients was(48.1 ± 45.9)IU/L,among which,the GGT levels of 69 cases (63.3%)were normal,and the levels of 40 cases(36.7%)were increased. After the treatment,the average GGT level of the pa?tients was(32.1 ± 23.4)IU/L,which decreased by 33.3%comparing with that before the treatment,and the difference had a statistical significance(U=2.17,P=0.01). The GGT levels of 65 patients decreased in different degrees. Among the 40 pa?tients whose GGT levels had increased before the treatment,the GGT levels of 31 ones returned to the normal. Conclusion The GGT level detection can accurately reflect the liver function in the patients with subclinical schistosomiasis ,and also it has certain clinical application value to judge the liver function damage and recovery of the patients before and after the pathogen treatment.
