Serum Ca, P, AKP, plasma iPTH, cAMP, urinary Hyp and BMC were measured in 31 cases of Graves' disease. The results showed that about 66.67% of the patients (including 21 controlled and 10 uncontrolled cases) had a decreased BMC, while serum Ca, P, plasma iPTH, cAMP were within the normal range. The data also showed that about 54.6% of the patients had increased serum AKP, but it would not exceed 25 U if no hepatic disease existed. There were positive correlations between serum T, and urinary Hyp, and between urinary Hyp and serum AKP, but a negative correlation between urinary Hyp and BMC. It was suggested that serum AKP and urinary Hyp could be considered as the indices of negative balance of bone metabolism in Graves' disease, and probably it was induced by excessive thyroid hormone directly.

AIM: To evaluate the effect of He-Ne laser combined with TDP irradiation in the treatment of herpes zoster ophthalmicus.METHODS: Totally 22 patients (22 eyes) with herpes zoster ophthalmicus were treated by He-Ne laser irradiation combined with TDP (Group A).Another 22 patients (22 eyes) with herpes zoster ophthalmicus (Group B) were treated by medication.The duration of the disease, the incidence of complications, and the time of pain relief were compared between the two groups.RESULTS: The cure rate of Group A was 91%, that of Group B was 73%, there was no significant difference between the two groups (x2=1.375, P>0.05).The average cure time of Group A was 8±2.22d, Group B was 12±1.88d, the difference between the two groups was statistically significant (t=5.22, P<0.05).The complication rate of Group A was 18%, Group B was 59%, the difference between the two groups was statistically significant (x2=6.86, P<0.05).The average pain relief time of Group A was 5±1.23d, Group B was 10±1.34d, the difference between the two groups was statistically significant (t=11.17, P<0.05).CONCLUSION: He-Ne laser combined with TDP irradiation can shorten the treatment time of herpes zoster ophthalmicus, shorten the course of disease, reduce the incidence of complications, relieve pain, with no significant effect on the cure rate of herpes zoster ophthalmicus.

T cell immune receptor with Ig and ITIM domains (TIGIT), a promising new target in cancer immunotherapy, plays a critical role in limiting adaptive and innate immunity against tumors. The extracellular domain of human TIGIT was used to immune BALB/c mice, and a new anti-human TIGIT chimeric antibody (c7D3) was developed. The mice in this study were used in accordance with the international guidelines for the care and use of laboratory animals, and the animal study was approved by the Institutional Animal Ethics Committee of AbMax Biotechnology. The biological activity of c7D3 was studied. The results showed that c7D3 exhibited high affinity for TIGIT and effectively inhibited the interaction between TIGIT and its ligands. Cell-based assays indicated that c7D3 induced strong luciferase signaling in TIGIT/CD155 signaling reporter assay and enhanced cytokine secretion in a T cell stimulation assay. The data showed that c7D3 has high binding affinity and excellent blocking bioactivity, supporting the further advancement for therapeutic application.

OBJECTIVETo provide reliable evidence of "J in three-needle therapy" for treatment of stroke.

METHODSMulti-central randomized controlled trials were adopted, 180 hemiplegia patients of ischemic stroke were randomly divided into a fin three-needle group (90 cases) and a routine acupuncture group (90 cases). Two groups were both treated with basic neurology therapies, and J in three-needle group was treated with J in three-needle therapy, three acupoints of tempora, hand and foot etc. were selected; the routine acupuncture group was treated with traditional acupuncture, Quchi (LI 11), Huantiao (GB 30), Futu (ST 32) etc. were selected. Both groups were treated with acupuncture for 5 weeks. The cognitive function score of functional comprehensive assessment scale (FCA), the scores of mini-mental state examination scale (MMSE) and modified Barthel index (BI) were compared before and after treatment between two groups. Results After treatment, the scores of FCA, MMSE and BI in both groups were significantly improved compared to those before treatment (P < 0.01, P < 0.05); the improvement of FCA score, MMSE score and BI score in the J in three-needle group were superior to those of the routine acupuncture group after treatment (P < 0.01, P < 0.05). The total effective rate of 85.4% in the J in three-needle group was superior to tohat of 70.0% in the routine acupuncture group (P < 0.05).

CONCLUSIONJ in three-needle acupuncture treatment can obviously improve the cognitive function and activity ability of daily life of hemiplegia patients after stroke, and the therapeutic effect of J in three-needle therapy is superior to that of traditional acupuncture treatment.

OBJECTIVETo prepare a DNA Microarray that can detect 8 common species of food borne bacterial pathogens in south China.

METHODSAll the 70mer oligo probes were designed on the characteristic genome loci of the 8 species of food borne bacterial pathogens. Eight subarrays corresponding to the 8 food borne bacterial pathogens were spotted onto the slide and integrated into a pan-array on the chip. A number of identified and known bacterial samples from the storage bank were selected for the validation test.

RESULTSBased on the PPR ranking, for LM sub-array, the PPR of the 3 Listeria bacteria LM, Lin and Liv was 68.8%, 51.8% and 59.6%, respectively, while that of the non-Listeria bacterial samples was all below 43%. For VC sub-array, the PPR of VC sample was 54.1% and that of the non-VC bacterial samples was lower than 17.2%. For VP sub-array, the PPR was 66.7% for VP sample and below 24.2% for non-VP bacterial samples. For Sal sub-array, the PPR was 55.9% for Sal sample and below 50.5% for non-Sal bacterial samples. For Shi sub-array, the PPR of Shi sample and the non-Shi bacterial samples was 53.8% and below 36.6%, respectively. For SA sub-array, the PPR of SA sample and non-SA bacterial samples was 65.2% and below 22.7%, respectively. For CJ sub-array, the PPR of the 2 Campylobacter bacteria CJ and CC were 88.2% and 58.8%, respectively, and that of the non-Campylobacter bacterial samples was lower than 35.3%. For EC sub-array, the PPR of EC sample was 47.9%, and that of the non-EC bacterial samples was lower than 41.6%. Evaluation of the Biosafood-8 chip developed in this study by 18 biological samples from different origins demonstrated its good specificity and accuracy in the identification of the pathogens.

Increasing lines of evidence has been accumulated that nitric oxide (NO) and nitric oxide synthase (NOS) distribute plentifully in the rostral ventrolateral medulla (RVLM) and contribute to cardiovascular regulation. In the present study, the expressions of neuronal and inducible isoform of NOS (nNOS and iNOS) were observed in the RVLM of acute myocardial ischemia (AMI) Wistar rats experienced electroacupuncture (EA) treatment, thereby the cardiovascular effects of NO in the RVLM were investigated and the mechanism of acupuncture effect on AMI was inferred. The results indicated that in the AMI rats, cardiac functions were markedly attenuated with high serum level of brain natriuretic peptide (BNP) and norepinephine (NE), the number of nNOS-immunoreactive cells and nNOS mRNA exprossion in the RVLM area were increased, while those of iNOS were lowered. EA at "Neiguan" acupoints (Pe 6) 30 min daily for successive 5 d resulted in an improvement of the cardiac functions, decreases in NE and BNP levels; it also increased the expression of iNOS and decreased the expression of nNOS in the RVLM. These results suggest that the curative effect of acupuncture on AMI is possibly attributable to the differential regulation of NOS/NO in the RVLM, leading to decreased sympathetic outflow and improvement of cardiac functions.

OBJECTIVETo investigate the characteristics of phase II metabolic enzymes in mouse embryonic stem (ES) cell-derived liver tissue.

METHODSMature hepatocytes were differentiated from embryonic stem cells in cultured mouse embryoid bodies (EB) at d18. Western blot was used to detect the expression of uridine 5'-diphosphate glucronosyl transferase (UGT1a1,UGT1a6) and microsomal glutathione S-transferases 1(mGST1) during the differentiation course.The derived liver tissue was incubated with UDPGA and 7-HFC,the formation of 7-HFC glucuronide was detected by HPLC to examine the total activities of UGT1a1 and UGT1a6. Furthermore, the microsomes were incubated with CDNB and GSH,and the mGST1 activity was measured by spectrometry.

RESULTSAn increase tendency of UGT1a1 expression was noticed during the differentiation course. UGT1a6 and mGST1 were not detected in the earlier stage until d18 of differentiation. The metabolic activity of mGST1 in the derived hepatocytes was 7.65 nmol/min/mg on d18.

CONCLUSIONThe ES cell-derived liver tissue possesses partial metabolic function of phase II enzymes on d18 of differentiation,which might be used as a model for in vitro research on hepatic pathophysiology and phase II drug metabolism.
