Objective To observe the therapeutically effect of kangnao liquid on Pi3k mRNA and Aktm RNA ex-pressions in rats with focal cerebral ischemia-reperfusion (I/R) injury. Methods 180 male SD rats were randomly divided into 6 groups:sham operated group, model group, three kangnao liquid groups (high-dose, medium-dose and low-dose) and nimodipine group. Rats in kangnao liquid groups were administrated with kangnao liquid of 24 g/(kg · d), 12 g/(kg · d) and 6 g/(kg · d), orally once a day. Rats in nimodipine group were given nimodipine 1 mg/(kg · d). Rats in model group and sham group were treated with the same volume of distilled water for 7 days. The animal model of middle cerebral artery occlusion (MCAO) was established by a monofilament method from right internal carotid artery. The neurological evaluation was per-formed 24 h after reperfusion. The in situ hybridization was used to investigate the expression levels of Pi3k mRNA and Akt mRNA in rats on 12 h, 24 h, 48 h, 72 h and 168 h after ischemia for 2 h. Results Compared with model group, neurological functions were improved significantly in kangnao liquid groups. The expression levels of Pi3k mRNA and Akt mRNA were al-so significantly higher in kangnao liquid groups than those of model group. The expression levels of Pi3k mRNA and Akt mRNA were significantly higher in nimodipine group than those of model group, but which were lower compared with those of high-dose and medium-dose kangnao liquid groups. Conclusion Kangnao liquid can protect nerve cells by enhancing the expressions of Pi3k mRNA and Akt mRNA in rats with cerebral ischemia-reprefusion injury.

Objective To compare the perioperative safety and curative effects oflaparoscopic adrenal sparing surgery (ASS) with laparoscopic total adrenalectomy (TA) for aldosterone producing adenoma (APA).Methods An online systematical retrieval was performed with Pubmed,ScienceDirect,Springerlink,the Cochrane library,CNKI and China Biology Medicine disc for clinical comparative studies published before May 2016,these studies reported the treatment of ASS/partial adrenalectomy (PA) versus TA for APA.The selected studies were applied to Revman 5.3 software for meta-analysis.The main contents were perioperative outcomes (operative time,intra-operative blood loss,and length of hospital stay) and postoperative efficacy (cure rate,partial response rate,inefficiency rate).Results A total of 9 clinical studies (3 English documents and 6 Chinese documents) with 1036 patients were included into the final analysis,among which 544 patients were assigned to ASS group and 492 in TA group.The analyzed results demonstrated no statistical significance between ASS group and TA group on operative time (WMD:-2.09min,95％CI:-9.86-5.67,P=0.60),length of hospital stay (WMD:-0.10d,95％CI:-0.32-0.12,P=0.36),intra-operative blood loss (WMD:1.13ml,95％CI:-8.86-11.12,P=0.82),cure rate (OR=l.07,95％CI:0.73-1.58,P=0.72),partial response rate (OR=0.85,95％CI:0.57-1.27,P=0.43) and inefficiency rate (OR=2.15,95％CI:0.32-14.34,P=0.43).Conclusion For surgical treatment of APA,ASS is technically safe,can achieve reliable postoperative efficacy and a similar therapeutic effect compared with TA,so deserves further application in clinical practice.

Objective To explore the psychomotor development in 12 month old infants born after in vitro fertilization with a control group of infants concieved naturally.Methods A matched control study was performed on psychomotor development of 12-month-old infants concieved with use of assisted reproductive technology(in vitro fertilization only).The control group was matched according to maternal age,parity,social class and level of parental education.The suitable mothers were invited to participate at the 28th week of gestation and were followed up to delivery.The infants of the two groups were followed up to 12 months old and a formal developmental assessment was done with the Children Development Center of China(CDCC) scales of infant development.Results The incidences of preterm birth,low birth weight and twin pregnancy were significantly higher in the assisted conception group.No statistically significant difference was found in the mental development index and psychomotor development index between assisted conception and control groups.Conclusions The levels of psychomotor development in 12 months old infants born after in vitro fertilization are normal.But as the incidences of preterm birth,low birth weight and multifetation are significantly higher in vitro fertilization group,it need to follow up the ongoing development of these children.

According to the requirements of the ‘three guidance’ talent-cultivation model pro-posed by our university, humanistic spirit was permeated from multi angels during the process of phys-iology. Students'occupation quality was cultivated; physiology knowledge and clinical practice was combined for students; early contacting with clinical knowledge was conducted and teacher-student role reversal method was applied to train students' communication skills. Teaching practice showed that the reformed teaching model not only can ensure the quality of teaching but also can improve the comprehensive quality of students.

Because of the population aging,the increase of the stroke patients and the need for rehabilitation,the treatment only in the rehabilitation department of the hospital is far from the satisfaction of people's demands of the service of rehabilitation.It is important to extend the community-based rehabilitation.Compared with the rehabilitation in hospitals,it is more economy,efficiency and convenience for stroke patients in community-based rehabilitation services,and further improve the rehabilitation effect of stroke patients.

Objective: To observe the effect of different moxibustion durations on rats with rheumatoid arthritis (RA) and to evaluate the relationship between moxibustion amount and moxibustion efficacy.Methods: Eight rats were randomly selected as a normal group from the 40 male Sprague-Dawley (SD) rats, and the other 32 rats were used to establish typeⅡ collagen-induced RA models. After successful modeling, the 32 rats were randomly divided into a model group, a moxibustion for 20 min group, a moxibustion for 40 min group and a moxibustion for 60 min group, with 8 rats in each group. Rats in the normal group did not receive modeling and moxibustion intervention; rats in the model group did not receive moxibustion after modeling; rats in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group were treated with moxibustion at Shenshu (BL 23) and Zusanli (ST 36) for 20 min, 40 min and 60 min, respectively. Six days were a course of treatment, with a total of 3-course treatments and a 1-day rest between the courses of treatment. After treatment, the serum levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, arthritis index (AI) scores, toe volumes and pathological score of synovitis were evaluated in the rats.Results: Compared with the normal group, the serum IL-1β and TNF-α levels, and the toe volumes in the model group were increased, and the differences were statistically significant (P<0.01), before the treatment. Compared with the model group, the serum IL-1β and TNF-α levels, toe volumes and arthritis index (AI) scores were significantly decreased in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group (P<0.05 orP<0.01 ). Compared with the moxibustion for 20 min group and the moxibustion for 60 min group, serum IL-1β and TNF-α levels, toe volumes and AI scores were decreased more significantly in moxibustion for 40 min group, and the differences were statistically significant (P<0.05 orP<0.01). There were no significant differences in serum IL-1β and TNF-α levels, AI scores and toe volumes between the moxibustion for 20 min group and the moxibustion for 60 min group (allP>0.05). The synovial histopathological improvement was the most obvious in the moxibustion for 40 min group, when the synovial histopathological changes were compared among the moxibustion for 20 min group, moxibustion for 40 min group and moxibustion for 60 min group.Conclusion: The therapeutic efficacy of moxibustion for 40 min in RA rats was more significant than that of moxibustion for 20 min and moxibustion for 60 min, indicating that the duration of moxibustion is the main factor affecting its therapeutic efficacy.

[Objective]To study the dental status,the development of jaw and the size of sella turcica of children with ectoder-mal dysplasia(ED).[Methods]Panaramic radiography and lateral cephalograms of six ED individuals(age range of 6~7 years,five males and one female)were obtained. The dental status was record. 17 measurements about the jaws and the sella turcica were mea-sured and compare them to Chinese children without ED syndrome.[Results]The mean number of missing teeth was 22.3 in perma-nent dentition and 16.2 in primary dentition;The teeth that most likely to absent were permanent lateral incisor ,maxillary first premo-lar,maxillary primary lateral incisor and mandibular primary central incisor,and all remaining teeth are in conical shape. Lateral cephalometric measurements showed that all ED subjects had lower ANS-Ptm,which suggested a short maxilla. Low Co-Po,ANB, NA-PA,N-Me,N-ANS and ANS-Me values that were found in all subjects,as well as low SNA,Y-axis,MP-FH,S-Co,and high SNB,NP-FH,NP-FH that were noted in some subjects showed counterclockwise rotation and protrusion of mandible with short-er length in ED subjects. Some subjects had low ANS-Me/N-Me × 100%and high N-ANS/N-Me × 100%,representing a short facial height. Five cases represented lower length and diameter of sella turcica;two cases showed lower depth of sella turcica ,indicating the abnormal development of sella turcica.[Conclusion]The results of this study suggest that the dentition ,jaws and sella turcica in ED children differs when compared to individuals without this syndrome.
