[Objective]AIM To explore the differentiation of neural stem cells from rat embryonic spinalcord in the serum free condition culture medium of OECs.[Method]OECs were acquired by dissection ofolfactory nerve ensheathing and cultured for 20 hours,then suspending cells were put intoselective culture medium and cultured in the fibernectin coated plate.The activity of OECs was detected by MTT method on different periods and the best situation was selected out and serum-free cultured.Exudates of OECs was added into neural stem cells of the third generation.The differentiation of neural stem cells were observed under inverted microscope.The neural stemcells cultured were identified by immumofluorescence method.[Result]The activity of OECs was high on the 9~(th) day and the 12~(th) day.The serum free condition culture medium of OECs induced 53% neuralstem cells to differentiate into neuron-like cells and 42% neural stem cells into astrocytes cells.[Conclusion]The activity of OECs on different periods is different.The serum free condition culture medium of OECs can obviously induced neural stem cells to differentiate into mature neuronecells.

Objective To evaluate the serum 25?hydroxy vitamin D3 level in patients with multiple sclerosis(MS)and normal healthy population,as well as the correlation between addition of oral 1,25?hydroxy vitamin D3 and the prevention of MS relapse and progression. Methods There were 60 cases in the relapsing?remitting MS(RRMS)group and 68 cases in the healthy group,respectively;and the differences in the sex,age, serum 25?hydroxy vitamin D3 level of the two groups were counted and evaluated. In addition ,the 60 cases of patients were divided randomly into the hormone therapy group and the addition treatment group ,with 30 cases in each group;the addition treatment group was added oral calcitriol soft capsules on the basis of the hormone therapy group;EDSS score evaluation was conducted on the two groups 6,12 and 24 months after treatment,the relapse frequency was counted after 24 months,and the relapse interval was calculated. Results The serum 25?hydroxy vitamin D3 levels in the patient group and the healthy group were(18.75 ± 8.35)nmol/L and(23.28 ± 9.31)nmol/L, respectively. There were statistically significant differences in the relapse frequency (P < 0.01),the relapse interval(P < 0.05),and EDSS score(after 24 months)(P < 0.05)between the hormone therapy group and the addition treatment group after treatment;while the differences in the EDSS score (after 6 months)(P = 0.457) and the EDSS score(after 12 months)(P = 0.118)between the two groups showed no statistically significance. Conclusion The serum 25?hydroxy vitamin D3 level in MS patients was markedly lower than that in normal healthy population. Addition of 1,25?hydroxy vitamin D3 contributes to preventing the relapse rate of MS and extending the relapse interval;in addition,maintaining long?term of oral 1,25?hydroxy vitamin D3 facilitates to delaying the progression of disabled disease.

OBJECTIVETo explore the impacts on the cognitive level of the children with mental retardation (MR) treated with JIN's three scalp needling therapy and the training for cognitive and perceptual disturbance so as to seek the more effective therapeutic method for the treatment of MR in children. Methods Sixty-six MR children were randomized into a head-point needle-retaining therapy + training group (group A) and a training after acupuncture group (group B). Seven cases and 12 cases were dropped in the two groups respectively. Twenty-six cases accomplished the treatment in the group A and 21 cases in the group B. In the group A, the points on the head were stimulated and the needles were retained (30 min after the general acupuncture, the needles on the body points were removed; and those on the head points were retained for 1 h, including Sishenzhen, Naosanzhen, Zhisanzhen and Niesanzhen). Simultaneously, the training for the cognitive perceptual disturbance was combined. In the group B, 1 h after needle retaining at the body points and head points, all the needles were removed; the training for the cognitive perceptual disturbance was followed. The treatment was given once a day, and the treatment for 3 months was required. Before and after treatment, the Wechsler intelligence scale for children (WISC) was used for evaluation and observation of verbal intelligence quotient (VIQ) , performance intelligence quotient (PIQ) and full-scale intelligence quotient (TFIQ) and score changes of 11 items such as information, picture vocabu; lary, arithmetic, picture generalization, comprehension, etc.

RESULTSAfter treatment, FIQ, VIQ and PIQ scores were different significantly as compared with those before treatment (all P<0. 01). In the group A, the results of picture vocabulary, animal egg laying, maze, block design and geometric figure were all improved significantly (all P<0. 05). In the group B, the results of information, comprehension, block design and geometric figure were all improved significantly (all P<0. 05). After treatment, concerning the value difference in FIQ and PIQ of the two groups; the changes in the group A were more significant (both P<0. 01). After treatment, the results of picture vocabulary and maze were improved significantly in the group A as compared with the group B (both P<. 01). The IQ categories changed apparently after treatment in the two groups, toward the higher level in tendency generally, but without significant difference (both P>0. 05).

CONCLUSIONThe simultaneous treatment with head point retaining of JIN's three needling therapy and the training for cognitive and perceptual disturbance obviously improves children patients' verbal comprehension, expression ability, hand-eye coordination ability, attention, logical reasoning ability and visual perception. The efficacy is better than that in the treatment of the training after acupuncture.

Metabolic bone disease of prematurity (MBDP) is an important chronic disease in the neonates. The metabolic abnormalities of calcium, phosphorus, vitamin D and others in premature can lead to decline of bone mineral content, decrease of trabecular bone quantity, thinning of cortical bone, etc., which can cause rickets in severe cases and even fracture. Low gestational age and low birth weight of premature are important risk factors for metabolic bone disease. The diagnosis relies on clinical features as well as laboratory, radiological and ultrasonographic examinations. The treatment includes reinforcement of the passive movement, supplementiation of the calcium, phosphorus and vitamin D, better prevention and so on. Early detection, early diagnosis, and early treatment can reduce the incidence of sequelae of metabolic bone disease, and reduce the long-term impact on premature infants.

Objective:To investigate the effects of scenario-based teaching on the comprehensive abilities of nurses in the department of cardiac surgery from the perspective of the script theory.Methods:From March 2020 to April 2022, 65 junior nurses in the department of cardiac surgery of The First Affiliated Hospital of Air Force Medical University were divided into control group ( n=33) and experimental group ( n=32). The control group received scenario-based teaching, while the experimental group received scenario-based teaching from the perspective of the script theory. The two groups were compared in terms of theoretical and skills assessment scores, comprehensive clinical abilities, and satisfaction with teaching. SPSS 20.0 was used to perform the t test. Results:After 6 months of teaching, the experimental group showed a significantly higher theoretical score [(91.37±5.34) vs. (86.22±6.28), P<0.05] and a significantly higher practical score [(91.55±5.36) vs. (84.48±4.52), P<0.05] compared with the control group. The total score and individual scores of comprehensive clinical abilities were significantly higher in the experimental group than in the control group ( P<0.05). The experimental group was superior to the control group with respect to the total score and individual scores of satisfaction with teaching. Conclusions:Scenario-based teaching from the perspective of the script theory can improve the comprehensive clinical abilities of nurses in cardiac surgery.

Objective To discuss the impacts of stroke center construction upon therapeutic indexes for di-agnosing and treating patients with acute ischemic stroke. Methods Patients were divided into a control group (180 patients)and a formal group(245 patients)based on the time of stroke center construction.Patients in both groups were recorded time points in the course of diagnosis and treatment,and compared in number of cases with intravenous thrombolysis,number of cases receiving intravascular interventional therapies,DTN(door-to-needle) time,number of deaths,National Institutes of Health Stroke Scale(NIHSS)scores upon grouping,NIHSS scores after four weeks,NIHSS scores after 3 months,days of hospital stay and hospital charges.Results After the con-struction of the stroke center,time spent in different links were decreased.The number of cases with pure intrave-nous thrombolysis and DTN time(shorter than 60 min)were increased,and the difference were statistically signifi-cant(P<0.01).The number of cases who only received intravascular interventional therapies is increased,mean-while,DTN time was decreased,NIHSS scores after 4 weeks was increased and NIHSS scores after 3 months were also increased(P < 0.05)in these cases. No statistically significant differences existed in number of cases who were treated by bridging with intravenous thrombolysis in combination with intravascular interventional therapies and death cases(P=0.153,P=0.247).There were no statistically significant differences in days of hospital stay and hospital charges(P=0.152,P=0.406).Conclusions After the stroke center construction,it is helpful for significantly improving medical institutions′diagnosis and treatment of stroke,reducing time of such diagnosis and treatment in different links,shortening DTN time,increasing thrombolysis rate,improving patients′prognosis and bringing more benefits to patients with acute ischemic stroke by optimizing procedures for diagnosing and treating stroke.

Ataxia-telangiectasia (AT) is a rare autosomal recessive genetic disorder resulting from ataxia-telangiectasia mutated(ATM) gene mutation.ATM involved in DNA repair.ATM is made up of 66 exons.Its mutation forms are complex, including nonsense mutation, missense mutation, shear site mutation, insertion and deletion, etc.The patients are characterized by progressive cerebellar atrophy and ataxia, disturbance of eye movement, telangiectasia and dystonia, a high risk of cancer and immunodeficiency.These patients are also hypersensitive to radiotherapy.AT is often neglected at the early stage.As pediatricians, we should pay attention to early ataxia and conduct genetic testing as early as possible to avoid radiation exposure.

In the past decade, significant progress has been made in the study of epilepsy-causing genetic mutations and the molecular mechanisms of epilepsy clinical manifestations.A growing number of studies have shown that the mechanism of action of pathogenic genes related to clinical symptoms shows significant correlation.In the selection of antiepileptic drugs for patients with different gene mutation, early identification of pathogenic genes has guiding significance for the selection of antiepileptic drugs.This review summairzes common epilepsy pathogenic genes, including ion channels genes, cellular metabolism related genes and cell signaling pathway related genes, and research progress on therapeutic targets corresponding to pathogenic genes in recent years.As research deepens, specific gene defects and their machanisms of action provide a basis for studying new treatment methods.

Objective To explore the characteristics of distribution of TCMsyndrome elements of disease nature between active stage and stationary stage of patients with hepatitis cirrhosis,and to study the corre-lation between the TCMsyndrome elements and serum level of homocysteine (Hcy).Methods By using Information Collection Form ofHepatitis Cirrhosis drafted by our research team,a national multicenter and cross-sectional epidemiological survey was conducted to collect the general condition,symptoms,and blood samples from which the serum Hcy levels were obtained.In accordance with Standard ofHepatitis Cirrhosis Syndrome Elements Differentiation,the TCM syndrome elements of nature of the patients were determined.Then the correlation of the TCMsyndrome elements and the serum levels of Hcy was investi-gated at active stage and stationary stage.Results Altogether 715 patients were included.The frequen-cy of all syndrome elements in patients of active stage were higher than those in patients of stationary phase,in which the element of blood stasis,yin deficiency,qi deficiency,yang deficiency and water re-tention showed statistical differences (P <0.05).The serum level of Hcy in patients of active stage was higher significantly than that of stationary stage (P <0.05).The Hcy level of patients with yin deficiency pattern was lower than that of patients without yin deficiency pattern,the same as element of damp heat, qi stagnation and yang deficiency;however,the situations of element of blood stasis,qi deficiency and water retention were quite the reverse.In the patients of stationary stage,the serum levels of Hcy showed significant difference between qi stagnation group and non qi stagnation group (P <0.05).In the pa-tients of active stage,the levels of Hcy showed difference between yin deficiency group and non yin defi-ciency group,as well as the element of qi deficiency (P <0.05).Conclusion The frequency of TCM syndrome elements and the serum Hcy level in patients of active stage higher than those of patients of sta-tionary stage,reflected the degree of hepatic inflammation and severity of disease.That the correlation between the Hcy level and the TCMsyndrome elements of nature could provide the evidence for pathologi-cal basis and standardization study of TCMsyndrome elements in patients with hepatitis cirrhosis.

Objective To analyze the distribution of diseases with TCMpattern of spleen-stomach damp-ness-heat (SSDHP)and the prescriptions and Chinese herbal medicines involved,so as to guide TCM clinical practice and further research on SSDHP.Methods Taking “SSDHP”(Chinese:脾胃湿热证) as subject term or title /keyword,the databases of China National Knowledge Infrastructure(CNKI),Wan-fang Data Knowledge Service Platform and VIP Information were systematically retrieved,from the begin-ning of the databases to 31 December,2015.The articles related to treatment on SSDHP were collected, and the database was established by using Microsoft Excel 2010,on which data were descriptively statisti-cal analyzed.Results 109 articles were eligible from total 1 681 retrieved ones.The top two diseases with SSDHP were digestive system disorders (86.41%)and dermatoses (5.83%).The common formu-la directed at clearing heat and dampness including Pingwei Powder,Huopu Xialing Decoction,and Sanren Decoction,combined with specific medications for exact symptoms.The common Chinese herbal medications with frequency more than 1 percent were listed as the following:Golden Thread (Huangli-an),Pinellia Tuber(Banxia),Official Magnolia Bark(Houpu),Liquorice Root (Gancao),Dried De-coctionerine Peel (Chenpi),Baical Skullcap Root (Huangqin),Indian Bread (Fuling),Dandelion (Pugongying),Agastache Rugosus (Huoxiang),Atractylodes Rhizome (Cangzhu),Coix Seed (Yiy-iren),Round Cardamon Fruit (Baidoukou),Largehead Atractylodes Rhizome (Baizhu),Orange Fruit (Zhiqiao),Immature Orange Fruit (Zhizi ),Corydalis Rhizoma (Yanhusuo ),White Peony Root (Baishao),Medicinal Evodia Fruit (Wuzhuyu),Dried Ginger (Ganjiang),Bamboo Shavings (Zhu-ru),Virgate Wormwood Herb (Yinchen),Grassleaf Sweetflag Rhizome (Shichangpu),Turmeric Root Tuber (Yujin),Immature Orange Fruit (Zhishi),Chinese Thorowax Root(Chaihu),Common Bletilla Tuber (Baiji),Danshan Root (Danshen),Bitter Apricot Seed (Kuxingren),Villous Amomum Fruit (Sharen),Common Aucklandia Root (Muxiang),Finger Citron (Foshou),Talc (Huashi).Conclu-sion Now,the diseases with SSDHP were most common in digestive system,but also in other systems. And the prescription and Chinese herbal medicines should be applied by holistic conception,combination of disease and pattern and pattern differentiation and treatment.Classic herbal formulas in TCM ancient books are still playing the strictly key roles in clinical practice,but proved formulas of modern outstand-ing senior traditional Chinese practitioners and Hospital Preparations also are paid more attention by re-searchers.
