1.The study of quantitative evaluation of hypoxia of the patients with pulmonary heart disease
Chinese Journal of Practical Nursing 2011;27(2):62-64
Objective To find a grading method for assisting in evaluating hypoxia degree of patients with pulmonary heart disease non-invasively. Methods To design a quantitative method to score degree of hypoxia of 67 patients with pulmonary heart disease by using acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) as a frame and to make comparative analysis between the grading result and artery blood gas to find the correlation. Results There was a negative correlation between evaluation mark and pH、PaO2、SaO2 and a positive correlation between the evaluation mark and PaCO2, according to statistics. Conclusions Although the grading table of hypoxia evaluation can not substitute blood gas analysis, acting as a non-invasive method to assist in evaluating the hypoxia degree of patients with pulmonary heart disease, it can not only relieve patients' repeated punctuation pain, but also achieve the goal of estimating hypoxia.Consequently the non-invasive method to evaluate hypoxia is of clinical value.
2.Research progress of the new tumor suppressor gene SLC5A8
International Journal of Surgery 2013;40(8):547-550
Current research suggests that SLC5A8 is a new candidate tumor-suppressor gene whose expression is reduced or deficient in human thyroid cancer,esophageal cancer,gastric cancer,colon cancer and acute myeloid leukemia.The gene is in human chromosomes 12q13-23,and encoding proteins that belongs to the members of the family of sodium/glucose transporters.It is sodium-coupled carrier that transfer short chain fatty acid,lactic acid,nicotinic acid and iodide.The exon 1 of GPG island methylation and histone acetylation can make SLC5A8 gene express silenced and promote the occurrence of tumor.of all transporter substrates of SLC5A8 expresses,butyrate,propionate and pyruvate function as histone deacetylase inhibitors and can be mediated apoptosis of many kinds of tumor cells,which may be the mechanism of inhibiting tumor.
3.Searching of anatomy teachers' participating in neurosurgery case-based teaching
Chinese Journal of Medical Education Research 2015;(5):512-514
Neuroanatomy knowledge is the key to improve the teaching quality of neurosurgery and anatomy teachers' participation in neurosurgery teaching can obviously improve teaching effect. Combined with case-based teaching, we enabled medical students to master the system knowledge from the basic to the clinical , cultivating their clinical thinking ability and the ability to solve clinical problems. Cooperation between clinical medicine teachers and basic medicine teachers can promote the update of knowledge, work out teaching plans together, and improve the quality of teaching.
4.Analysis of predictable factors of intra-operative aneurysm rupture of anterior circulation aneurysm treated by clipping
Clinical Medicine of China 2015;31(8):742-746
Objective To discuss the predictable factors for the occurrence of intra-operative aneurysm rupture(IAR).Methods A total of 84 patients with 101 aneurysms treated by neurosurgical clipping from September 2009 to September 2014 were retrospectively analyzed.The statistic analysis was performed for the risk factors of IAR such as aneurysm location,aneurysm sac,dome/neck ratio,direction,pre-operative Hunt-Hess Scale,history of hypertension and operation time.Results Eighteen cases (21.4%) occurred LAR (18 (17.8%) of aneurysms) during the operations,2 patients (2.4%) died.Statistic analysis revealed that preoperative Hunt-Hess scale (P =0.042),history of hypertension (P =0.038),aneurysm sac (P =0.012),dome/neck ratio(P=0.027),direction (P =0.010) and operation time (P =0.002) were the predictable factors for the occurrence of IAR,while the location of aneurysm was not included (P =0.199).Conclusion The IAR may be the result of the synthesis of various factors in the occurrence of intracranial aneurysms clipping.Hypertension history,Hunt-Hess scale,direction,aneurysm sac,operation time and dome/neck ratio 1.78-2.89 are the predictable factors for the occurrence of IAR and the combination of various factors leads to the occurrence of IAR.

Military Medical Sciences 2014;(12):945-947
Objective To study the expression of carbonic anhydrase 9(CA9) in clear cell renal carcinoma(ccRCC), and the relationship between the expression and recurrence .Methods Paraffin-embedded tissues from 53 ccRCC cases were collected during the past 3 years,and immunohistochemistry was used to detect the expression of CA 9.Fifty-three cases were followed up to evaluate the disease-free survival ( DFS) and recurrence .Association of CA9 expression with recurrence was then analyzed .Results Localized RCC recurred in eleven cases , the median DFS was 10 months, the integral optical density ( IOD) of the recurrent cases was 230 879 .84 ±64 878 .72 while the IOD of the thirteen nonrecurrent cases was much higher,444 993.31 ±146 946.27(P<0.01).Conclusion There might be a positive correlation between the low expression of CA9 and the recurrence of ccRCC .CA9 may help predict the ccRCC patients ’ prognosis.

9.Strengthen and standardize clinical study of dry eye
Ophthalmology in China 1993;0(03):-
Dry eye is the most common ocular surface diseases encountered in the clinic.At present,a system for dry eye diagnosis and treatment has initially been formed in China,but there are still many clinical issues need to be resolved.It is important to improve the definition of dry eye and construct a more rational classification system;pay attention to the epidemiological investigation of dry eye;standardize diagnostic procedures for dry eye;establish the dry eye diagnostic criteria and the correct treatment concept.We propose to develop the clinical guidelines on dry eye classification,diagnostic criteria and treatment principles.
10.An Experimental Study of Pathological Changes of Thyroid after Severe Burns and Their Mechanisms in Rats
Journal of Third Military Medical University 1983;0(03):-
Thirty percent TBSA full thickness burns due to napalm was inflicted to the rats and the pathological changes of the thyroid were studied under optical and electron microscopy and with peroxidase histochemistry for 15 days. The alterations of serum T3 and T4 levels accompaniying the pathological changes were also observed dynamically.It was found that the pathological changes of the thyroid could be distinguished into three phases as follows.1. The phase of injury inhibition. This phase existed from the 2nd to the 24th hour postburn and was characterized by marked damage on the follicular epithelium.2. The phase of structural and functional recovery. This phase entended from the 3rd to the 6th day postburn. In this phase, the damages on the thyroid became abated and its damaged structure showed a tendency to recover.3. The phase of active function. It extended from the 10th to the 15th day postburn. The organelles to synthesize and release thyroid hormone were fonud well developed.The alteration of T4 run parallelly to the pathological changes of the thyroid in all the stages, while T3 level was continously inhibited because of the lower serum concentration of T4, the metabolic disturbance of T4 deiodination, and the inhibition of thyroid secretion in the early postburn stage and the metabolic disturbance of T4 deiodination in the middle and late postburn stages. In the early postburn stage, the inhibition of thyroid peroxidase was an important factor of functional inhibition of the thyroid.
