OBJECTIVE:
To investigate the clinical application of carbon nanoparticles staining in cervical lymph node dissection on clinical neck lymph nodes the negative (cN0 period) thyroid papillary thyroid carcinoma (PTC).
METHOD:
This retrospective analysis comprised 100 papillary thyroid cancer patients who met inclusion criteria,and they were randomly divided into the nano-carbon group (50 cases) and control group (50 cases). They underwent lobectomy, subtotal thyroidectomy or total thyroidectomies and were given elective central compartment neck dissection (CCND). The number of detected lymph nodes in each group was summed, and pathological examination was conducted. The number of lymph nodes (dyedor not dyed) and the location of metastatic nodes were recorded separately.
RESULT:
In the nano-carbon group the average number of eliminated lymph nodes is significantly more than that of the control group(P<0.05). The metastasis lymph nodes in the nano-carbon group was higher than that in the control group(P<0.01). Among 100 cases, 2% had temporary vocal cord palsy, and 8% had temporary hypoparat hyroidism. No case of permanent vocal cord palsy or permanent hypocalcemia was observed.
CONCLUSION
The dyed lymph nodes can be easily identified and can be used as a guide for lymphnodes dissection in papillary thyroid carcinoma operation.

5.Role of Nrf2/Keap1/ARE signaling pathway in respiratory diseases
Chinese Pharmacological Bulletin 2015;(11):1488-1492
Nrf2/Keap1/ARE is an important signaling pathway in maintaining the balance between peroxide and antioxidants. Once oxidative stress happened, Nrf2/Keap1/ARE would be ac-tivated to regulate the expression of downstream antioxidant pro-teins that could reduce the injury from oxidative stress and the level of oxidative stress. Recent researches show that Nrf2/Keap1/ARE signaling pathway is closely related to refractory re-spiratory diseases such as pulmonary fibrosis (PF), lung canc-er, chronic obstructive pulmonary disease (COPD), suggesting that Nrf2/Keap1/ARE signaling pathway may be a potential ther-apeutic target. This review focuses on the role of Nrf2/Keap1/ARE signaling pathway in refractory respiratory diseases in order to further understand the related mechanism and provide evidence for the diagnosis and treatment of refractory respiratory diseases.

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.

9.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.

Objective To investigate the distribution and drug resistance of pathogen for pulmonary infection in cervical spinal cord inju-ry (CSCI) patients, and analyze the application of antibiotics. Methods From January, 2014 to June, 2015, 156 patients with CSCI were re-viewed. The bacteriology and drug resistance were investigated, as well as the application of antibiotics. Results There were 45 cases with nosocomial infection of 68 times, and 106 strains of bacteria in total. The top four Gram-negative pathogens were Klebsiella pneumonia (17.9%), Pseudomonas aeruginosae (15.1%), Encherichia coli (11.3%) and Acinetobacter baumannii (8.5%). The main Gram-positive cocci was Staphylococcus aureus (9.4%), and the main fungi was Candida tropicalis (0.7%). Gram-negative bacteria was resistant to the second or third generation cephalosporins and quinolones moderately or severely, but sensitive toβ-lactamase inhibitor combinations and aminoglyco-sides. The main Gram-positive cocci were sensitive to vancomycin. The application of antibiotics needed to be improved. Conclusion The Gram-negative bacteria are the chief pathogen for pulmonary infection in CSCI patients, which show multiple drug-resistant. It is significant to monitor the drug resistance of bacteria and optimize antibiotics.
