Journal of Chinese Physician 2001;0(05):-
Objective To explore the diagnostic value of transbronchial lung biopsy(TBLB), CT-guided percutaneous lung biopsy and sputum cytology for unknown lung mass. Methods The clinical data of 101 inpatients with unknown lung mass were retrospectively analyzed. Results Among the 101 cases, 73 cases underwent fibrous bronchoscopic examination, 18 cases underwent CT-guided percutaneous lung biopsy, and 10 cases underwent both of them.The diagnostic coincident rate of the two methods was 70%. 54 cases were diagnosed lung carcinoma by pathology. The sensitivity and specificity of TBLB for diagnosing central type of tumor were 88% and 100%, respectiely, and those for diagnosing peripheral type of tumor were 43% and 100%, respectively. The sensitivity of CT-guided percutaneous lung biopsy was 80%,while the specificity was 100%. Complication frequency in the CT-guided percutaneous lung biopsy was 22%, and much higher than that (12%) in the TBLB. Only 30% cases underwent sputum cytology examination, and the positive rat was 6%. Conclusion Sputum cytologic examination is a convenient and cheap method, but its diagnostic rate is relatively low. TBLB was the first choice for examining central type of lung mass. For the peripheral type of lung mass, examination method was selected based on the location and size of the mass.
4.Correlation between left ventricular filling type and geometry modality and functional change of left ventricle in patients with hypertension
Chinese Journal of Clinical Pharmacology and Therapeutics 2004;0(08):-
AIM: To investigate the correlation between the left ventricular filling type and geometry modality and functional change of the left ventricle in patients with hypertension. METHODS: Systolic function indexes (FS and EF) and diastolic function indexes (E, A, EAT, EDT, E/A,IVRT) in 120 patients with hypertension were measured by two dimensional ultrasonography (2-DUS) and M-mode and Doppler ultrasound. RESULTS: A rate of 83.5% in patients with hypertension appeared assured plump and configuration changes of left ventricle, and a rate of 84% in patients with hypertension appeared abnormal left ventricular filling function. The morphologic indexes were significantly different clearly in different left ventricular filling types, and the filling indexes were also significantly different in diferent left ventricular shapes. CONCLUSION: IVRT is a more important index than other factors to decide the left ventricular filling function. LVMI plays more important role than other factors in the left ventricular filling function.
5.Modified classification method of corneal dystrophy at the molecular level
Chinese Journal of Experimental Ophthalmology 2013;(2):204-208
Corneal dystrophy represents a group of inherited corneal diseases with progressive accumulation of deposits in different layers of cornea,resulting in loss of corneal transparency and visual impairment,or even blindness.Initial classification of corneal dystrophy was upon involved cornea layer,and it is insufficient for some multi-layer lesion.With the current progress in molecular genetics,researchers proposed a new classifying way based on genetic information of corneal dystrophy.A revised classification has been recommended by the International Committee for Classification of Corneal Dystrophies (IC3D).The clinical manifestation,histological and genetic basis of the disease are integrated in the classification system,so it is regarded as to be more scientific and reasonable.Recent years,our laboratory performed genetic screen on some Chinese pedigrees with corneal dystrophy,mainly focusing on the corneal dystrophy-associated genes such as human transforming growth factor beta induced (TGFBI) gene,which reveals the relationship of the different mutations on TGFBI gene with clinical phenotypes.Our studies further indicated that the corneal dystrophy classification method based on molecular level is a more scientific and practicable method.Some updated information on the clinical phenotypes and molecular aspects of corneal dystrophy were provided here aimed to offer the aid to the differential diagnosis and management of these diseases.

China Pharmacy 2016;27(21):2907-2909
OBJECTIVE:To observe the efficacy and safety of atorvastatin calcium combined with metoprolol in the treatment of chronic congestive heart failure (CHF). METHODS:207 CHF patients were randomly divided into control group (102 cases) and observation group (105 cases). Control group received cardiac,diuretic,vasodilating and oxygen inhalation,Metoprolol tar-trate tablet with initial dose of 6.25 mg,2-3 times a day,then increased 6.25-12.5 mg based on the improvement,2-3 times a day. Observation group additionally received 80 mg Atorvastatin tablet,twice a day. The treatment course for both groups was 16 w. Clinical efficacy,cardiac functions [left ventricular ejection fraction(LVEF),left ventricular end systolic diameter(LVESD),mi-tral early diastolic and late diastolic peak flow velocity ratio(E/A)],blood lipids [lipoprotein(a)Lp(a),triglyceride(TG),total cholesterol(TC)] levels before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant (P<0.05). Before treatment,there were no significant differences in cardiac functions and blood lipids in 2 groups(P>0.05). Af-ter treatment,the LVEF and E/A in 2 groups were significantly higher than before,and observation group was higher than control group,LVESD,Lp(a),TG and TC were significantly lower than before,and observation group was lower than control group,the differences were statistically significant (P<0.05). And there was no significant difference in the incidence of adverse reactions (P>0.05). CONCLUSIONS:Based on conventional treatment,the efficacy of atorvastatin calcium combined with metoprolol is su-perior to metoprolol in the treatment of CHF,with better safety.

8.Foot Overpronation: Influence on Body Alignment and Managements (review)
Chinese Journal of Rehabilitation Theory and Practice 2016;22(1):72-74
The foot overpronation is termed as pronation persisting more than 25%of stance phase in a walking cycle, which may re-sult from some antenatal or postnatal conditions. Overpronation would lead to abnormal alignment of ankle, knee, pelvis and spine, and re-sult in a set of syndromes of chronic pain. The Navicular Drop Test and the Foot Posture Index are often used as the assessment tools, how-ever, there are several empirical ways for clinic. Foot orthoses, special shoes, taping and training of muscle strength are effective on overpro-nation as well as chronic pain.
