The BL21(DE3) transformed recombinant plasmid pET32/E6 had expressed HPV18E6 recombinant protein effectively. The optimum conditions of expression were 37 ℃, 1 mmol/L IPTG. Conclusion:Prokaryotic expression vector pET-32a(+)-HPV18E6 was successfully constructed. The high-level expression of HPV18E6 was achieved in E.coli BL21(DE3).

Nissl stain and immunocytochemical methods were used to observe the structure of the subnuclei of interpeduncular nucleus in human neonatal brain and their localization of substance P-, leu enkephalin-, and serotonin (5-HT)-like immunoreactive elements. It was detected that the human neonatal interpeduncular nucleus could be divided into five subnuclei, including: the dorsal, dorsolateral, lateral, central, and intermediate subnuclei. The immunocytochemical results showed that the substance P-containing cell bodies and fibers or terminals were distributed chiefly in the dorsolateral, lateral subnuclei and the ventral part of the intermediate subnucleus; the enkephalin-containing cell bodies and fibers or terminals were concentrated in the central subnucleus; and meanwhile the serotonin-containing cell bodies and fibers or terminals were found mainly in the dorsal subnucleus.

Using immunohistochemical technique, the distribution and development of substance P (SP)-, L-enkephalin (L-Enk)- and serotonin (5-HT)-like immunoreactivity in Gudden's dorsal tegmental nucleus (GDTN) of human foetus (fetal age 11.5 to 35 weeks)and neonate (two days) were demonstrated. Gudden's dorsal tegmental nucleus in the human might be divided into pars centralis and pars peripheralis; and the time of initial appearance for SP-, L-Enk- and 5-HT-like immunoreactivity in GDTN was different. SP-like immunoreactive fibers and terminals appeared first and were distributed mainly in the pars centralis and their density was very high. L-Enk-like imunoreactive cells, fibers and terminals were distributed in the pars peripheralis. 5-HT-like immunoreactive cells, fibers and terminals were distributed in the medial part of the GDTN; As the foetus developed further, SP-, L-Enk- and 5-HT-like immunoreactivity in the GDTN showed their own special ontogenetic changes respectively

OBJECTIVE:To study the mechanism of Aurantii fructus immaturus(AFI)and its main active ingredients in pro-moting gastrointestinal motility of model rats with spleen deficiency. METHODS:170 rats were randomly divided into blank group (10 rats) and modeling group (160 rats),rats in modeling group was induced models with spleen deficiency by bitter cold diar-rhea+irregular diet. After modeling, rats were randomly divided into model group, naringin (NA) low-dose, medium-lose, high-dose groups(3.267,6.535,13.070 mg/mL),neohesperidin(NE)low-dose,medium-lose,high-dose groups(3.865,7.730, 15.460 mg/mL),synephrine(SY)low-dose,medium-lose,high-dose groups(0.252,0.504,1.008 mg/mL),compatibility groups with 3 monomer ingredients (NA-NE-SY) low-dose,medium-lose,high-dose and AFI water decoction low-dose,medium-lose, high-dose groups(0.104,0.208,0.416 g/mL,calculated by crude drug),ig,once a day,10 mL/kg,for 7 d. After the last admin-istration,gastrin (GAS) in serum,and acetylcholine (ACh),motilin (MTL),substance P (SP),vasoactive intestinal peptide (VIP)levels in plasma were detected. RESULTS:Compared with blank group,GAS level in serum and ACh,MTL,SP levels in plasma in model group were reduced(P<0.01),VIP level in plasma was increased(P<0.05). Compared with model group,ex-cept for the GAS level in serum showed no obvious change in NA high-dose group and SY doses groups,other medicine groups were obviously increased (P<0.05 or P<0.01);the ACh levels in serum were obviouly increased in NE high-dose group,SY high-dose group and AFI water decoction low-dose group(P<0.01). MTL levels in plasma were obviously increased in NE medi-um-dose,high-dose groups,SY high-dose group,compatibility low-dose,medium-dose groups and AFI water decoction medi-um-dose,high-lose groups (P<0.05);SP levels in plasma were obviously increased in NA low-dose,medium-dose groups and NE doses groups(P<0.05 or P<0.01);VIP levels were reduced in NA low-dose group,SY high-dose group and AFI water decoc-tion low-dose,medium-lose groups(P<0.05). CONCLUSIONS:AFI may promote the gastrointestinal motility of model rats with spleen deficiency by promoting the secretion of GAS,ACh,MTL,and inhibiting the secretion of VIP;there are differences be-tween AFI and the 3 monomer ingredients in regulation of gastrointestinal hormones.

Method A total of 65 VLBWI(born during September 2015 to September 2016 with 28-32 weeks gestational age;1000 g ≤ birth weight < 1500 g;exclusion of combination with congenital deformity)were randomly divided into the early application of noninvasive respiratory support as observation group (n = 33) and the application of endotracheal intubation with gen respiratory support as control group (n = 32). Comparison of two groups was carried out by SPSS in terms of incidence of endotracheal intubation,BPD,pulmonary infection,pneumothorax,and necrotizing enterocolitis,together with rescue ratio,total oxygenation time and hospitalization. Results No significant difference was found on incidence of pneumothorax,necrotizing enterocolitis and rescue ratio between two groups. The incidence of endotracheal intubation,BPD,pulmonary infection and total oxygenation time was markly decreased in observation group. Conclusion Early application of noninvasive respiratory support benefits VLBWI via reducing incidence of endotracheal intubation,BPD,pulmonary infection, total oxygenation time.

Objective To control the nosocomial infection and avoid the second pollution of thereclaimed medical apparatus to the washing area of supply room. Methods Count, classification and place of the reclaimed medical apparatus went along at the same self-designed categorizing pedestal of the muhi-function apparatus.No absorbing cloth was needed on the table-board, the dirty water flew into the outfall of the sewer directly and automatically, the discreteness could be unpicked, washed and lis-terized after work. Results It avoided the collision of the apparatuses, shortened the time of counting effectively and reduced the chance of pollution.It also avoided the waste of the manpower, the material resources, the time and the second environmental pollution. The effects of the two table-boards after disinfection had statistical difference (P＜0.01). Conclusions The categorizing pedestal of the mul-ti-function apparatus makes the reclaim and handling of the polluted apparatus more standard and to re-move the pollution more thoroughly.

Prokaryotic expression vector of mouse HPV16E6 gene was constructed. A pair of primers were designed according to the digestion sites in plasmid pGEX-KG and the HPV16E6 gene sequence published by GenBank. The DNA fragment of 321bp was amplified by PCR from the HPV recombinant plasmid with HPV16E6 gene, then cloned into pGEX-KG and transformed into the host E. coli strain JM109. The fragment was conformed to the original sequence, which indicated that fusion expression vector pGEX-KG-HPV16E6 was constructed. The pGEX-KG-HPV16E6 plasmid was taken and transformed into BL21(DE3) for expression. Induced by IPTG at 37 degrees C, the expression product of HPV16E6 gene was identified by SDS-PAGE and Western blot. HPV16E6 fusion protein had been expressed successfully in the form of inclusion bodies, the molecular weight of fusion protein being 38 kD. Meanwhile, the optimum condition of HPV16E6 fusion protein expression was induced with 1.0 mmol/L IPTG for 4h. The fusion protein reacted specifically with the antibodies against HPV16E6. HPV16E6 gene was successfully expressed in E. coli, which could be used as a basis for preparing HPV16E6 vaccine in human.
