Textbook is the embodiment of teaching content and teaching method.Stereoscopic teaching materials construction is the key of making good education reform and increasing teaching quality and one of the most important constructions in medical colleges and universities.Taking the features of physiology into consideration,this paper elaborated the contents of stereoscopic teaching materials and discussed some advantage of teaching material construction.

Objective To investigate the relationship between the genesis of hypertensive disorder complicating pregnancy and neurokinin B (NKB).Methods The serum NKB levels of 229 women including non-pregnant women (n = 62),normal pregnant women (n = 80) and pregnant women with preeclampsia (n=37) or gestational hypertension (n= 50) were examined by enzyme linked immunosorbent assay.The umbilical blood levels of NKB and the NKB mRNA expression in the pregnant women were also tested by fluorescent quantitative reverse transcription-polymerase chain reaction technique.ANOVA and paired t-test were applied.Results (1)The maternal plasma NKB levels of normal pregnant women,patients with gestational hypertension or preeclampsia were significantly higher than that of non-pregnant women,respectively [(28.2±6.6)μg/L,(31.5±5.2)μg/L,(70.5±8.9)μg/L vs(3.2±1.8)μg/L,P＜ 0.01].In preeclampsia,gestational hypertension and normal pregnancy group,the NKB level in umbilical blood [(121.4±9.3)μg/L,(60.5±7.2)μg/L,(40.8±6.3)μg/L] were significantly higher than that of maternal plasma(P＜0.01).(2) The maternal plasma NKB level in gestational hypertension group was higher than that in normal pregnancy group,while the difference had no statistical significance (P＞0.05).The maternal plasma NKB level in preeclampsia group was higher than that in gestational hypertension group and normal pregnancy group (P＜0.01).Forty-eight hours after delivery,the maternal plasma NKB levels significantly decreased in the normal pregnant,gestational hypertension and preeclampsia group [ (14.1±4.2) μg/L,(16.4±3.8) μg/L,(25.4±5.2) μg/L],compared to the values before delivery (P＜0.01).(3) The expression of NKB mRNA in placenta of preeclampsia group was significantly higher than that of gestational hypertension group and normal pregnancy group [(3.8±0.6) × 10-3 vs(1.7±0.4) × 10-3 and (1.6±0.3) × 10-3,P＜0.01].No statistical difference was found in the expression of NKB mRNA in placenta between gestational hypertension group and normal pregnancy group (P＞0.05).Conclusions Elevated NKB level in placenta and maternal or umbilical blood might play an important role in the development of hypertensive disorder complicating pregnancy.

With the deterioration of environment, and the excessive collection of wild resources, the wild populations of Myla- bris phalerata Pallas are less and less, almost extincted in many traditional distribution areas. It is necessary to breed M. phalerata artificially for sustainable utilization. Food preference of adult M. phalerata is the key to its provenance screening and domestication in the artificial breeding. In this paper, the food preference of 3 geographical populations of M. phalerata was studied. The results showed that the food preferences of adult M. phalerata in different geographical populations were different. The adult M. phalerata in Wuming preferred cucumber flowers, gourd flowers and melon flowers. The adult M. phalerata in Tianlin preferred cowpea flowers. And the adult M. phalerata in Guangzhou preferred cowpea flowers and gourd flowers. Gourd flowers were the most attractive food for the adult M. phalerata of 3 geographical populations of M. phalerata.

OBJECTIVE:To systematically review the efficacy and safety of Elemene injection combined with chemotherapy in the treatment of gastric carcinoma,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from CBM, CJFD,VIP Database,Wanfang Database,Medline,EMBase,Cochrane Library and American Medical Association Database,ran-domized clinical trials(RCT)about Elemene injection combined with chemotherapy in the treatment of gastric carcinoma were col-lected,Meta-analysis was performed by using Rev Man 5.3 software after data extracting and quality evaluating by Cochrane 5.1.0. RESULTS:Totally 7 RCTs were enrolled,involving 434 patients. Results of Meta-analysis showed recent efficacy [RR=1.38,95%CI(1.14,1.67),P=0.001] and improvement rate of life quality [RR=1.36,95% CI(1.15,1.60),P<0.001] of Elemene injection combined with chemotherapy in the treatment of gastric carcinoma were significantly higher than only chemotherapy. The incidence of Ⅲ-Ⅳ leukemia inhibition [RR=0.58,95%CI(0.37,0.91),P=0.02],incidence of Ⅰ-Ⅳ hemoglobin inhibition [RR=0.76,95%CI(0.60,0.95),P=0.02],incidence of Ⅰ-Ⅳ platelet inhibition [RR=0.69,95%CI(0.52,0.91),P<0.001] and Ⅲ-Ⅳ[RR=0.53, 95%CI(0.30,0.93),P=0.03] and incidence of Ⅰ-Ⅳ neurotoxicity[RR=0.69,95%CI(0.52,0.93),P=0.01] in test group were sig-nificantly lower than control group,the differences were statistically significant. CONCLUSIONS:Both efficacy and safety of El-emene injection combined with chemotherapy in the treatment of gastric carcinoma are good.

OBJECTIVE:To evaluate therapeutic efficacy and safety of ubenimex combined with chemotherapy in the treatment of malignant tumor,and to provide evidence-based reference in clinic.METHODS:Retrieved from Central,PubMed,CJFD,VIP and Wanfang database,randomized controlled trials (RCTs) about ubenimex combined with chemotherapy (trial group) vs.single chemotherapy (control group) in the treatment of malignant tumor were collected.The quality of studies were evaluated by bias risk evaluation criteria of Cochrane system evaluator manual 5.1.0 after screening literatures and extracting data.Meta-analysis was performed by using Rev Man 5.3 statistical software.RESULTS:A total of 12 RCTs were included,involving 762 patients.The resuits of Meta-analysis showed that:shorter-term response rate [RR=1.24,95 ％ CI (1.08,1.43),P=0.002] and the improvement rate of life quality Karnofsky score [RR=1.69,95％ CI(1.46,1.95),P＜0.001] in trial group were significantly higher than control group;the incidence of gastrointestinal toxicity [RR=0.74,95％CI(0.57,0.94),P=0.02] and leucocyte suppression rate[Ⅰ °-Ⅳ°(＜3 months):RR=0.54,95％CI(0.37,0.79),P=0.002;Ⅲ°-Ⅳ°:RR=0.44,95％CI(0.29,0.68),P＜0.001] were significantly lower than control group,with statistical significance.CONCLUSIONS:Ubenimex combined with chemotherapy can improve malignant tumor,shorter-term efficacy and life quality,and reduce gastrointestinal and marrow toxicity.

Objective To discuss the effect of Dickkopf-1 (DKK-1) on Wnt singal pathway during the differentiation of osteoblast in vitro.Methods The osteoblasts were obtained from the new rats and cultured in vitro.The 3 passages were divided into control group and DKK-1 group.The cells were cultured in DKK-1 and normal saline for morphogical detection,ALP activity detection and osteoblasts stained at 1 st,6th,12th,21st day.The Wnt was detected by RT-PCR.Results After cultured by the DKK-1 in vitro,the ALP and mineralization of osterblasts staining were prlonged with culture time.Compared with control group,the expression of Wnt was significantly reduced at the 21st day after induction (t =0.278,P ＜ 0.05).Conclusion DKK-1 can regulate the expression of Wnt during osteoblast differentiation,suggests that Wnt may be involved in osteoblast differentiation and can affect bone remodeling process.

Developing web-based teaching is one of the foremost tasks for medical education by using multimedia technology.This paper made a brief analysis on exploitation of physiological web-based teaching system,the advantages of web-based teaching and its application.

The network-based course is a teaching resource based on modern multimedia technology and network-based teaching environment.In order to improve the quality of teaching,we designed and developed the physiology interactive learning website,including online class,study column,online test and network resource database.The teaching practice indicates teaching by the website has many merits such as rich content,giving prominence to emphasis,combination of word and picture and good mutuality.
