1.Anatomical Observation and Clinical Significance of Suborbital Foramen and Infraorbital Canal
Journal of Kunming Medical University 1986;0(04):-
In this article, 100 maxilla samples of the Kunming area werc takcn for observing the suborbital foramen and infraorbital canal and their relative data. The purpose of this investigation was to provide an anatomical basis for the clinical block anesthesia of the infraorbital nerve and its branches. The results show that 93% of the suborbital foramen is an oval-shaped mono-foramen and 7% has a paraforamen, their exact positions on the maxilla being measured. The vertical diameter of the suborbital foramen averages 5.83mm, and the transverse one 3.05ram. The average value of the vertical diameter of the infraorbital canal is 11mm, its anterior part axis toward inferior, anterior and interior. 66% of infraorbital canals can be passed through smoothly by a ~#6 hypodermic needle, 12% with reistance and 22% can not be passed through.
2.Observation on Enamel Pearls in Extracted Teeth and their Clinical Significance
Journal of Kunming Medical University 1988;0(03):-
The incidence,location,shape and size of enmel pearls on l2379 extracted teeth were ob- served in this article. The results are as follow:The morbidlty of the enamel pearls is 2.49%.The most freguent morbidity is on the maxillary third molar,the second is on the mandible first molar.The freguent location is on the bifurcation of crown-cervical. The enamel pearls on maxillary molar often round and on the mandible molar are fusiform.The maximun diameter of enamel is 3.2mm,the minnimum is 0.5mm.,and its average diameter is 1.56mm. The author suggested that enmel pearls is one teind of developmental variations of tooth morphology,and it may be important influence on the pathogenesis,development,treatment and prognosis of the periodental diseases.
3.Observatiosn on Attached Cementicles on surfaces of Extracted Teeth and Their Clinical Significance
Journal of Kunming Medical University 1986;0(04):-
It is the purpose of this study to examine the prevalence and distribution of cementicles on different root surfaces of 524 extracted human teeth. The results are as follows:185 teeth had cementicles and the morbidity accouted for 35% of the sum total of investigation. Cementicles were seen on approximately over 50% of the canines and molars and fewer than 50% of the other teeth.On canines,cementicles were found most frequently in the mid- dle and apical thirds of the roots.On molars,cemwnticles were found frequently in furcations. A relationship with the presence of enamel projections at the cementenamel junction in molar furcations was noted.The findings suggested that cementicles frequent occurrance in certain locations be of grear clinical importance to periodontal diseases.
4.Comparation on effect of two kinds operation in treatment of recurrent pterygium with symblepharon
International Eye Science 2014;(12):2286-2288
AlM: To analyze the effect of corneal limbus stem cell transplantation and amniotic membrane transplantation in treatment of recurrent pterygium with symblepharon.
METHODS:Totally 80 cases of patients with recurrent pterygium and symblepharon were randomly divided into pterygium resection combined with limbal stem cell transplantation group and pterygium excision with amniotic membrane transplantation group, 40 cases in each group. All patients were followed up for 6mo after the operation, the recurrence rate of pterygium and symblepharon were observed.
RESULTS:There were 2 cases of recurrence in the group of corneal limbus stem cell transplantation (5%), 8 cases of recurrence in the group of amniotic membrane transplantation (20%), with statistical difference between two groups (P<0. 05).
CONCLUSlON:Two kinds operation could significantly reduce the recurrence rate of recurrent pterygium, but the corneal limbus stem cell transplantation group has the lower recurrence rate.
5.Research progress in a novel H17N10 subtype of bat influenza A virus.
Chinese Journal of Virology 2015;31(1):80-84
A novel H17N10 subtype of the influenza A viruses was found in bats in 2012. Protein sequence and structural analyses revealed that the HA17 and NA10 proteins of this strain are different from corresponding ones in known influenza A subtype viruses. Both HA17 and NA10 proteins cannot bind to sialic acid,which indicates that they may have novel functions. This article briefly describes the state of current research into the H17N10 subtype of bat influenza A virus.

6.Meta-analysis on Acupuncture Combined with Western Medicine for Treatment of Alzheimer's Disease
World Science and Technology-Modernization of Traditional Chinese Medicine 2015;17(4):836-840
This study was aimed to evaluate efficacy of acupuncture combined with western medicine in treatment of Alzheimer's disease (AD) with meta-analysis of data came from randomized controlled trials (RCTs). Databases both at home and abroad were comprehensively searched to collect efficacy data of acupuncture combined with western medicine versus western medicine in RCTs. The data was extracted from each study to conduct a meta-analysis with RevMan 5.2. The results showed that 10 studies measured up to standard. Seven studies reported effective cases were carried out by meta-analysis. The total RR was 1.25 [1.14, 1.38]. The funnel plot was approximately symmetry. It was suggested that effect of the therapy group was better than the control group (Z = 4.66,P<0.01). Four studies reported mini-mental state examination (MMSE) scores were carried out by meta-analysis. The total MD was 2.87 [0.64, 5.10]. The funnel plot was approximately symmetry. It was suggested that the therapy group was better than the control group on AD treatment in cognitive function improvement (Z = 2.52,P= 0.01). It was concluded that from current study, acupuncture combined with western medicine in AD treatment was definitely effective. However, it still required further study.
7.A positive analysis of China's health resources based on the Cobb-Douglas production function
Chinese Journal of Hospital Administration 1996;0(04):-
Health resources allocation, the cornerstone of health production capability, includes effective allocation of increments and rational readjustment of stocks. Using the least square method and variance analysis, the authors created a multilinear regression model on the basis of the calculation method and analysis principle of the Cobb-Douglas production function and in light of historical data in China's health sector and made a positive analysis of the current state of health resources allocation in China The result indicates that the input in health human resources has been insufficient and their contribution to production has been on the moderate side. Moreover, health resources allocation has shown decreasing return to scale on the whole.
