Ophthalmology in China 1994;0(02):-
Objective To investigate the status and capacity of eye care services in Yunnan Province in 2007. Design Cross-sectional questionnaire survey. Participants 165 medical institutions in Yunnan Province. Methods Using a standardized questionnaire designed by Ministry of Health,the all hospitals of county or above and eye hospitals in Yunnan Province were investigated during October to December 2007. Main Outcome Measures Number of ophthalmologists and ophthalmic nurses,surgical volume per year,out-patient volume per year and number of ophthalmologists who can operate cataract independently. Results Totally 165 hospitals covered Yunnan Province participated in this study (response rate was 100%). In all these institutions,there were 735 ophthalmologists and 771 nurses. 392 ophthalmologists could perform cataract surgery independently. Within 16 prefectures of Yunnan,Zhaotong prefecture had the least resources of ophthalmology (7 ophthalmologists per million population) while Kunming had 32 ophthalmologists per million populations. In 2006,58346 eye surgeries were performed in all these institutions,including 23833 cases of cataract surgeries. 27 hospitals were not able to provide cataract surgical services. Out 165 institutions,only 29 hospitals (17.6%) had advanced ophthalmic equipments and 6 hospitals (3.6%) did not have any ophthalmic equipment. Conclusion There are big differences of eye care services among different level and different location of medical institutions in Yunnan Province of China. Inappropriate distribution of human resources and low productivity are main issues. Further resources allocation and optimized use of resources in eye care services are needed to meet the needs of patients.

Chinese Journal of Postgraduates of Medicine 2010;33(34):12-14
Objective To investigate the electrophysiology mechanism of the P wave dispersion (Pd) and the maximum P wave duration (Pmax) in patients with paroxysmal atrial fibrillation (PAF),and evaluate the effect of the Pd and Pmax in the prediction of PAF. Methods Forty-eight patients with PAF (group PAF) were slected and divided into 2 sub-groups according to the organic heart disease,group PAF1 (20 cases, without organic heart disease) and group PAF2 ( 28 cases, with organic heart disease). Forty-six patients without PAF were selected as control group. The Pd and Pmax were measured from the 12-lead surface electrocardiogram (ECG). Results The Pd and Pmax in group PAF was higher than that in control group [(41.11 ± 4.97 ) ms vs. (27.77 ± 4.72) ms, ( 111.43 ± 8.01 ) ms vs. (95.57 ± 9.01 ) ms] (P < 0.05 ). The Pmaxin group PAF2 was significantly higher than that in group PAF1 (P < 0.05),and there was no significant difference in the Pd between group PAF2 and group PAF1 (P> 0.05 ). The specificity, sensitivity and positive predictive value of Pd ≥40 ms combined with Pmax ≥ 110 ms was 95.65%, 81.25% and 95.12%. Conclusion The Pd and Pmax in the patients with PAF are significantly higher than those in the patients without PAF, and Pd≥40 ms combined with Pmax≥ 110 ms can be used to predict the PAF more reliably and accurately.

Objective To observe the effect of maxillary sinus floor augmentation with transalveolar tech-nique and simultaneous implant.Methods 50 cases of patients with missing tooth in maxillary posterior region with insufficient vertical bone treated by author were selected.Maxillary sinus floor augmentation with transalveolar tech-nique and simultaneous implantation were given after local anesthesia.X -ray was given on the right day,2 weeks, 3 months and 9 months after operation.And the situation of osseointegration was observed.Results There were 2 cases of injuries of maxillary sinus mucoperiosteum in the 50 cases (4%),and no obvious complication was found for timely treatment.There were 5 cases of gingiva with obviously swollen around implant and BOP(+),and the symptoms were obliterated one week after paradental basic therapy and oral health guidance were given.All the situations of the osseointegration of implants were good,and no loosening or dropping case was found in follow up.One year after operation,the mean obsorbation of bone around the neck of implant was (0.9 ±0.3)mm.There was no obvious absorption of bone around implant,and obvious continuous image of maxillary sinus floor could be observed by imaging examination.The satisfaction of chew,pronounce,aesthetics,maintenance and comfort was all 100%,and 49 cases were satisfied with operation tolerance,and satisfaction rate was 98%.Conclusion Ther effect is desired to apply maxillary sinus floor augmentation with transalveolar technique and simultaneous implant under strict indication.And the satisfaction degree is high.
5.Clinical efficacy and safety of intracoronary verapamil during percutaneous coronary intervention in patients with acute coronary syndromes
Chinese Journal of Geriatrics 2012;31(4):290-293
Objective To examine the clinical efficacy and safety of intracoronary verapamil during percutaneous coronary intervention(PCI) in patients with acute coronary syndromes (ACS).Methods Totally 98 patients with ACS undergoing PCI were randomly assigned to two groups:verapamil group (immediately intracoronary verapamil 200 μg/2 ml heparinised saline,n=48) and intracoronary saline control group (immediately intracoronary 2 ml heparinised saline,n=50) after deploying stent.The follow up time was 3 months.Thrombolysis in myocardial infarction (TIMI)flow grade (TFG), corrected TIMI frame count (CTFC),TIMI myocardial perfusion grade (TMPG), myocardial blush grade (MBG) were assessed pre- and post-PCI and after drug administration.Echocardiography were performed one week after PCI. Incidence of major adverse cardiac events in hospital and 3 months follow-up were compared between the two groups. Results The differences in values of CTFC,TFG,TMPG,MBG after PCI were not found between two groups (P>0.05). However,after intracoronary drug administration,verapamil group was superior to control group in terms of CTFC (t=6.47,P<0.01),TFG (x2=5.17,P<0.01),TMPG(x28.25,P<0.01)and MBG(x2=2.12,P<0.05).After correcting the influencing factors,only CTFC was still improved in verapamil group than in control group (x2 =2.36,P<0.05).There were no significant differences between the two groups in TFG(x2 =0.58,P>0.05)and MBG(x2 =0.91,P>0.05) and TMPG (x2 =0.68,P>0.05).Echocardiographic results after PCI were similar between two groups (x2 =0.65,P>0.05).There was no difference in major adverse cardiac events between two groups (x2 =0.71,P > 0.05 ). Conclusions Application of intracoronary verapamil after deploying stent is effective,safety and worthy of popularization in view of improving post procedural coronary flow in patients with ACS.

7.A pathogenesis study of tic disorder in children based on pathogen incubation theory
Journal of Integrative Medicine 2007;5(6):612-5
Pathogen incubation theory includes "no manifestation after infection" and "manifestation after incubation". Clinical data showed that the incidence and recurrence of tic disorders in children had a strong relevance to six exogenous factors. The pathogenesis is similar to the pathogenic mechanism based on incubation of pathogen theory, so we proposed a theory of "tic disorder induced by incubation of pathogen". Pathogenic wind can be classified into exterior wind and endogenous wind. Pathogenic wind is more apt to move, rise and migrate. The characteristics of pathogenic wind, especially easy mobility, determine the symptoms and signs of tic disorder, for pathogenic wind can be characterized by vibration and involuntary movement such as convulsion and tremor. If exogenous pathogenic wind moves into half-exterior and half-interior phase from the exterior, both the exterior and interior syndromes should be treated at the same time. We should regulate the function of the liver and the lung, expel pathogenic wind by dispersing the lung, and calm endogenous wind by removing obstruction in the collaterals and soothing the liver.
8.A STUDY OF THE SOMATIC CHROMOSOME COMPLEMENT AMONG THE CHINESE
Acta Anatomica Sinica 1955;0(03):-
Leukocytes from peripheral blood of 70 normal Chinese,40 males and 30 females, were cultured in vitro according to a modification of Moorhead's method.Chromosome studies were carried out.Table I lists the results obtained including age group,metaphase plates counted and analysed and the chromosome number of each cell.92.4 per cent of 8031 counted cells had the diploid number(2n=46).Chromosome measurements were made from camera lucida drawings.Measurements were estimated to the nearest 0.1 mm on a fine metric scale.The relative length,arm ratio and centromere index of each chromosome were calculated from measurements of 18 haploid chromosome sets of 11 metaphase plates in 6 males and 4 females.The averages,range of variation and 99% confidence limits are listed in Table Ⅲ.Systematic studies of individual chromosomes under the light microscope revealed the following morphological characteristics.The short arms of all 10 acrocentric chromosomes from groups 13—15 and 21—22 could be shown to possess satellites,but in general only 2—8 of these chromosomes at a time carried satellites.In many cells the satellite-carrying chromosomes tended to associate with each other through their satellites.The number of chromosomes involved in each association varied between 2 to 5,occasionally 6.It was not rare to find secondary constrictions to occur regularly in certain regions of chromosomes 1,4,9,13,and 16.Attachments of satellites to such regions of chromosomes 1,4,9,and 13 were also observed.Karyotypic analysis of 357 metaphase plates led us to conclude that in most cases the unequivocal identification of chromosome pairs 4—5,6—12+X,13—15,19—20,and 21—22 was im- possible.Accurate characterisation of these chromosome pairs will have to await further technical advances. The length of the Y chromosomes was systematically measured in order to deter- mine its variability and heritability.Among our sample of 40 male subjects 29 had a Y chromosome slightly larger than chromosome 21,8 slightly smaller or larger than chromo- some 18(long Y chromosome),and 3 smaller than chromosome 21(short Y chromo- some).The heritability of the size of the Y chromosome was established(Fig.Ⅳ). “Spontaneous”aberrations were discovered in 34 of 70 cases.Aberration rates varied from 0.88 to 13 per cent.The relation between aberrations and radiation injuries was briefly discussed.
9.Hospitalized eye injury in a Chinese urban population: a retrospective analysis
International Eye Science 2010;10(10):1861-1863
AIM: To present the epidemiology, cause of injury, ocular status and final visual acuity after management of severe ocular trauma required hospitalization during 7 years in a representative urban Chinese population.METHODS: A retrospective analysis of the hospital admission files of ocular trauma patients admitted to the Daping hospital from January 2000 to December 2006 was carried out.RESULTS: A total of 268 patients were open-globe injury and the remaining 294 patients were closed-globe types. The most common causes of ocular injuries were metal (29.4%), explosive (14.6%) and stone (13.9%). And the visual outcomes of most of eye injury patients in this study were poor; half of injured eyes ended with visual acuity worse than 0.1.CONCLUSION: Therapeutic methods to ocular trauma make a great progress in recent years, but the visual outcomes are poor.
