Objective Different methods were used for the analysis of different medical and health institutions in Henan Province in 2012 of hospital bed utilization,to find bed utilization problems,and provide reference for the rational allocation of resources.Methods Static beds utilization model method (SBMA)and the method of rank sum ratio(RSR)were used for planning of data in“2012 health statistics yearbook of Henan province”,for comprehensive analysis of bed utilization efficiency.Results Among the medical and health institutions in Henan province in 2012,general hospitals,maternal and children hospitals(centers)are found with higher utilization of hospital beds,while other institutions (nursing homes),community health service centers(stations)are found lower.Conclusion Henan Province in 2012 was found on the whole with efficient utilization of hospital beds,yet with rooms of improvement for different medical institutions,especially those at the primary level.

Objective:To analyze the clinical characteristics and laboratory examinations of hospitalized children with influenza, and improve medical personal awareness of severe influenza.Methods:Data of inpatients with influenza from November 2018 to February 2019 at Shenzhen Children′s Hospital was collected, and the clinical characteristics and laboratory examinations were statistical analyzed.Results:Of the 702 cases, 464(66.1%) cases were mild influenza, and 238 cases(33.9%)were severe influenza; the median age was 3.8 years, and 457(65.1%) cases were 0 to 5 years old.The number of patients with basic diseases and wheezing symptoms in the severe group was more than those in the mild group, with statistically significant differences(all P<0.05). The white blood cell count, percentage of neutrophils, neutrophils to lymphocytes ratio(NLR), C-reactive protein and procalcitonin in the severe group were higher than those in the mild group, while the percentage of lymphocytes was lower than that in the mild group(all P<0.05). Logistic multivariate regression analysis showed that underlying diseases, wheezing and NLR were risk factors for severe influenza.The area under the curve of NLR for severe influenza was 0.574, whose best cutoff value was 1.43. Conclusion:Influenza virus infection among children is mainly influenza A, and mostly affected children are under 5 years old.The blood routine of children with severe influenza mostly showes increased white blood cell, mainly neutrophils increased significantly, and increased C-reactive protein and procalcitonin.Children with underlying diseases, wheezing symptoms during the course of the disease, and elevated NLR are more likely to progress to severe cases, and NLR cannot be used as a independent predictor of severe influenza.

To compare the postobturation pain and therapeutic effects in root canal therapy between two root canal filling materials: AH Plus and zinc oxide eugonol. Four hundred and twenty four teeth requiring root canal therapy were randomly divided into 2 groups: AH Plus ( trial group ) or zinc oxide eugonol ( control group) were used in treatment respectively. The pain intensity after treatment was evaluated by visual analogue scale. The therapeutic effects were evaluated by follow-up for 6 and 12 months. The pain intensity of trial group was significantly lower than that of the control group in 3rd and 7th day[8. 5% ( 18/212) vs. 15.6% (33/212),5.2% (11/212) vs. 14.6% (31/212),both P ＜0.05]. There were no significant differences in effictive rate between two groups after follow-up for 6 and 12 months[92. 5% ( 196/212) vs. 89. 6% ( 190/212 ) ,91.5% ( 194/212 ) vs. 88.7% ( 188/212 ), both P ＞ 0. 05]. AH Plus root canal filling paste used in root canal therapy can significantly decrease postoperative pain.

AIM:To find an efficient and simple surgical procedure of the external dacryocystorhinostomy ( EXT- DCR) in the treatment of chronic dacryocystitis.
METHODS:A total of 270 cases were performed in this retrospective study. A comparison of clinical effects and hemorrhage complications between the experimental group, in which 189 eyes of 167 patients that underwent traditional EXT-DCR without packing, and the control group, in which 121 eyes of 103 patients that underwent traditional EXT-DCR with Vaseline gauze were performed. The postoperative follow-up ranged from 6 to 36mo ( the mean follow-up was 15±3. 6mo).
RESULTS: There were no significant differences in the curative rates between the two groups (97. 9% vs 97. 5%, P>0. 05). But the incidence rate of moderate or severe postoperative nasal bleeding was lower in the experimental group (15. 9%, 30 eyes) than the control group (31. 4%, 38 eyes) and P<0. 01.
CONLUSION: The traditional EXT - DCR without packingis an effective procedure and is more effective in reducing moderate or severe postoperative bleeding when the intraoperative anastomose and the postoperative drainage are well done and the intraoperative bleeding is well controlled.

AIM:To optimize the technical parameters indica-daisy dropping pill(Flos chrysanthemi indici) through controlling the influencing factors. METHODS:To take weight variation of pills,comprehensive quality and disintegration time limited as index,the above factors were observed by orthogonal test. RESULTS:Good technological parameters of indica-daisy dropping pill were as follows PEG6000∶PEG400=54∶6 as matrix,dimethicone as refrigerant.Temperature of drug fluids of 70 ℃,internal and external diameter of dropper within 6.2 mm and 9.0 mm,proportion of drug and matrix(1∶3),30 dropping per minute.The weight variation of pills was small,type quality was good and disintegration time limited was short.The water absorbability was smaller than that of granules. CONCLUSION:The finished products are of good quality and appropriate for mass production.

BACKGROUND:Mkx (Mohawk, transcription factor) is one of the crucial factors in tendon formation, development and differentiation.
OBJECTIVE:To summarize the molecular structure, distribution and function of Mkx and its research process in the signaling pathways during tendon differentiation.
METHODS:The first author retrieved the databases of CqVip, CNKI and Medline from1990 to 2016 using the keywords of“Mkx, Mohawk, Irxl, tendon, tendon differentiation, tissue engineering, TGFβ, stem cel”in Chinese and English, respectively. The articles related to research process of Mkx in tendon tissue engineering were retrieved, and a total of 55 literatures were enrol ed final y.
RESULTS AND CONCLUSION:Mkx that expresses in various mesoderm-derived tissues plays an important role in the formation and development of tendon and tissue-engineered tendon formation. Although Mkx does not directly act on Scx (Scleraxis), it can regulate the differentiation of tendon progenitor cel s via transforming growth factor-β2 signaling pathway. Cel s from different species and different cel lines as wel as various cytokines for certain make different effects on Mkx involved in tendon tissue engineering.
