Chinese Journal of Information on Traditional Chinese Medicine 2016;23(6):31-34
Objective To discuss the application effect of TCM constitution recognition on TCM chronic disease refining health management for type 2 diabetes mellitus.Methods Totally 140 outpatients with type 2 diabetes mellitus from Chaoyangmen Community Health Center were selected and divided evenly into two groups after TCM constitution assessment. The study lasted for 2 years (1st August 2013–31st July 2015). The control group (70 cases) received diabetes community health management. In addition to routine community health management, TCM constitutional management was also administrated in the intervention group. The latter group received medicine, food, sport guidance according to the results of TCM constitution assessment. The blood glucose, blood lipid, BMI and waist-hip ratio of the two groups were monitored, and the self-management and life quality of patients were evaluated. Results After the intervention, significant improvement was found for fasting blood glucose, 2 h postprandial blood glucose, BMI, waist-hip ratio and blood lipid both in the control group and the intervention group, and the improvement in the intervention group was more obvious than the control group (P<0.05). The whole level of self-management and life quality was greatly increased in both groups, while improvement of the intervention group was much higher than the control group (P<0.05).Conclusion Integrated application of TCM constitutional theory in TCM chronic disease refining health management for type 2 diabetes mellitus will contribute to improving patients’ self-management, changing their clinical symptoms and finally improving their life quality.

5.The changes of PGI_2 and TXA_2 in the hepatic ischemic damage in rats and the protective role of indomethacin
Chinese Journal of Pathophysiology 1986;0(04):-
It is still contradictory whether PGI_2 and TXA_2 can influence hepatic is-chemic damage. Rats were divided into three groups at random. Group 1 and 2 were givensaline; group 3 were pretreated with indomethacin. 30 min before the induction of liverischemia drugs were injected into peritoneal cavity. After 2 h of ischemia and 2 hof reperfusion, the results showed that the TXB_2 content of ischemia group was higherand the P/T ratio was lower than that of the indomethacin group. The control groupshowed no change. Massive necrosis was observed in the ischemia group, but only focalnecrosis was seen in the indomethacin group. There was no hepatic necrosis in the controlgroup. The results suggested: 1. TXA_2 was an important cell injury agent; 2. Indomethacinhave protective effect on the reperfusion liver cell injury.

Adoptive cell transfusion based on chimeric antigen receptor (CAR) is a new approach for treating malignant diseases and even advanced malignancies. More patients with advanced malignancies are expected to benefit from CAR T-cells once the suitable target molecules are selected, the safe method of gene transduction is applied, and the side effects of CAR T-cells are prevented.
8.Effect of resin infiltration treatment on the colour of white spot lesions.
West China Journal of Stomatology 2014;32(3):306-309
OBJECTIVEThis study aimed to evaluate the effect of resin infiltration and fluoride solution on masking different demineralized white spot lesions by assessing color change.
METHODSArtificial white spot lesions were produced on 60 human molars. Each sample had at least two enamel surfaces opened (named A and B). The samples were randomly divided into groups 1, 2, and 3 according to their time of demineralization (24, 48, and 72 h). After demineralization, the A spot of each sample was treated by resin infiltration. The B spot was treated with 0.1% fluoride solution daily for 30 days. After the remineralization of the B spot, resin infiltration was used again on the B spot of each sample. Color assessment was performed by a spectrophotometer in five distinct stages: baseline, after the production of artificial caries, after resin infiltration of A spots, after 30 days of fluoride solution treatment of B spots, and after resin infiltration of remineralized B spots.
RESULTSBefore demineralization, the L* values of spots A and B in all groups were not significantly different (P > 0.05), whereas the L* values of spots A and B were significantly increased after demineralization. The L* values of A spots recovered significantly after treatment by resin infiltration (P<0.05), but only groups 1 and 2 reached the baseline. The L* values of B spots had no significant differences (P > 0.05) after fluoride treatment compared with that after demineralization. After resin infiltration on B spots, the L* values recovered but could not reach the baseline nor the level of A spots treated by resin infiltration only.
CONCLUSIONResin infiltration is a more effective treatment for masking white spot lesions than traditional fluoride treatment. The effect of masking white spot lesions has certain relationships with the degree of demineralization and activity of the lesion.

9.The study progress of HSP-105 in tumor on applied and basic research fields
Cancer Research and Clinic 2009;21(10):713-715
Heat shock protein (HSP) 105 is a 105x103 stress protein that belongs to the HSP-110 family. It is released by tissues in response to a wide variety of stresses including infection and ischaemia. Studies have shown that the molecule is involved as a biochemical mediator of heat induced apoptosis by binding to p53 at scrotal temperatures and dissociating from it at suprascrotal temperatures in testicular germ cells. Recent studies have shown that HSP-105 is over-expressed in various malignancies besides in normal testicular tissue. HSP-105 may be a candidate of testis antigen.
10.TNF-α expression induced by NF-κB in pulmonary intravascular macrophages of rats with hepatopulmo-nary syndrome and the effect of pyrrolidine dithiocarbamate on the expression
Clinical Medicine of China 2008;24(10):993-996
Objective To study the expression of both nuclear factor-κB(NF-κB)and tumor necrosis fac-tor-α(TNF-α)in pulmonary intravascular macrophages(PIM)of rats with hepatopulmonary syndrome (HPS)and the effect of pyrrolidine dithiocarbamate(PDTC)on their expression.Methods The Sprague-Dawley(SD)rats were randomly divided into four groups:control,control+PDTC1CCl4,CCl4+PDTC groups.Arterial blood was collected for measurement of blood gas.Venous blood was sampled for hepatic function and endotoxin level.The mesenteric lymph nodes were dissected for bacteriology studies.Proteins of NF-κB and TNF-a of lung tissue were examined by immunohistochemistry.The activity of NF-κB in lung tissues was measured using electrophoretic mobility shift assay (EMSA).By real-time polymerase chain reaction (PCB)using SYBR Green I,the mRNA expression of TNF-α in lung tissues were detected.Results CCl4 group developed HPS with decreased PaO2 and PaCO2,increased alveolar-arterial oxygen difference(A-aDO2),abnormal hepatic function and increased endotoxin level.Culture-positive mes-enteric lymph nodes were found in 62.5%(5/8)of CCl4,group and 66.7%(6/9)of CCl4+PDTC group(P>0.05 J.All lungs from CCl4 and CCl4+PDTC group showed no accumulation of larse mononuclear macrophagelike cells within the lumen of numerous small muscular and nonnulscular pulmonary vessels.The percentages of vessels with more than 1O adherent macrophages was 60.8%(292/480)in CCl4 group but only 19.6%(106/540)in CCl4+PDTC group(P<0.01).The protein expression of NF-κB and TNF-α Was localized to PIM in CCl4 group.The NF-κB activity and mRNA expression of TNF-α in CCl4 group was significantly higher than that in control,con-trol+PDTC group and CCl4+PDTC group(P<0.05).Conclusion The TNF-α expression in PIM induced by NF-κB play an important role in HPS.The inhibitor of NF-κB PDTC can repress PIM activation and decrease the ex-pression of TNF-α.As result.HPS severity is reduced.
