Sixty four infants (25 males and 39 females), including 9 under nour- ished and 4 prematures, were fed with a commercial spray dried soybean milk preparation, while 32 (17 males and 15 females) were fed with a whole cow's milk powder diet, and 48 (24 males and 24 female) were fed with either human milk or fresh cow's milk. There were 5 pairs of twins, one of each pair was fed with the soybean preparation; and among the other 5, 2 were fed with cow's milk powder diet and 3 were fed human milk.The ages of the infants at the start of the observation were. 41 under one month, 76 at two months, and 28 at three months. Their ages at the conclusion were all one year.Twenty five mg of ascorbic acid and 1-2 drops of concentrate fish liver oil, furnishing 5000 I.U. of vitamin A and 500 I.U. of vitamin D, were supplied daily to all infants from the very beginning. Foods, including egg yolk, rice porridge, wheat flour noodles, soybean curd, chopped meat or vegetables etc were supplemented at the proper ages.Infants fed with the soybean milk product all had goo'd appetite, and no digestive disorder. Most of them passed formed stools once or twice a day. Only a few passed thin stools 5-6 times a day at the beginning, and changed to excrete formed stools after three weeks.The average daily calorie intake of the normal infants fed with the soybean product at the age of five months was 107 kcal; the prematures took 144 kcal, while the undernourished took 147 kcal.The growth rate of the infants fed with the soybean product was normal; the average growth curve is below that of infants fed with cow's milk powder diet or human milk before the 7th month, and there is practically no difference between the three curves after this age.Among the twins, those who took the soybean product all grew better in height and weight than their siblings.The average age of the eruption of the first tooth of the infants in the three groups were all at the 7th month. The blood hemoglobin and red cell count of the infants in the three groups were all normal.As to the serum alkaline phosphatase activity, 3.3% of the infants in the soybean food group and 12.5% of the infants in the human milk group were above 15 Bodansky units at the beginning, and all fall below 15 units at the end of the observation.X-ray photographs of the long bone at the beginning revealed that, among 55 infants, there were 4 had signs of rickets, 3 had doubtful rickets in the soybean food group, 48 had doubtful rickets in the human milk group. No signs of rickets were observed in the three groups at the end.It may be concluded that the nutritional quality of the spray dried soybean milk preparation seems to be equal to, if not better than, that of whole cows milk powder or human milk.

ObjectiveTo analyze the craniocerebrum ultrasonographic images of the infants born by women with hypertension in pregnancy and investigate the effect of hypertension in pregnancy on neonate brain injury and brain development.MethodsTo assess the brain injury and brain development, 106 infants born by women with hypertension in pregnancy (study group) and 200 infants born by women without high risk factors during perinatal period (control group) in the neonatal intensive care unit of First Affiliated Hospital of Harbin Medical University between 2013 and 2014 underwent brain ultrasonography. The abnormal ultrasound images and the constitution of abnormal ultrasound images distribution in two groups were compared. The relationship between the abnormal ultrasound images and the degree of hypertension in pregnancy were analyzed.ResultsThe brain ultrasonographic result of the infants : (1) In the group with hypertension in pregnancy, the abnormal ultrasound images were found in 78 cases (73.6%). For the preterm infants, the solitary abnormality was found in 41 cases (25 cases of cerebral white matter injury, 14 cases of peri-intraventricular hemorrhage and 2 case of brain hypoevolutism) and multiple abnormalities were found in 15 cases; for the full-term infants, the solitary abnormality was found in 17 cases (12 cases of peri-intraventricular hemorrhage, 3 cases of hypoxic-ischemic encephalopathy and 2 case of brain hypoevolutism) and multiple abnormalities were found in 5 cases. (2) In the group without high risk factors, abnormalities were found in 73 cases (36.5 %). For the preterm infants, abnormal ultrasound images were found in 45 cases, including solitary abnormality found in 30 cases (24 cases of cerebral white matter injury, 4 cases of peri-intraventricular hemorrhage and 2 case of brain hypoevolutism) and multiple abnormalities found in 15 cases; for the full-term infants, the abnormal ultrasound images were found in 30 cases, including solitary abnormality found in 24 cases (10 cases of peri-intraventricular hemorrhage and 14 cases of hypoxic-ischemic encephalopathy) and multiple abnormalities found in 6 cases. (3) There were obvious statistical significances between the comparativeness of two groups (χ2=38.119,P<0.001), but there were no statistical significances in the constitution of the abnormal ultrasound images distribution between the two groups (χ2=0.552,P=0.759). (4) There were statistical significances between the comparativeness of the abnormal ultrasound images and the degree of hypertensive disorder complicating pregnancy (P<0.001). ConclusionCraniocerebrum ultrasonography is the first choice to detect and monitor brain abnormal and can provide basis for clinical diagnosis, treatment and intervention at early stage for the infants born by women with hypertension in pregnancy.

BmK AngM1 is a long-chain scorpion toxin purified from the venom of Buthus martensii Karsch. It has been reported to exhibit evident analgesic effect and low toxicity, and has the potential to be a novel analgesic drug. The BmKAngM1 gene was transformed into Pichiapastoris GS115. Mut+ and Mut(s) recombinant strains were screened by phenotype and Mut+ recombinant strains were used to detect BmK AngMl gene copy number in the real-time PCR. Expression of BmK AngM1 in the Mut+ recombinant strain was compared with that of the Mut(s) recombinant strain with the same single copy of BmK AngM1 gene under the same condition. The results indicated that the transcription level of BmK AngM1 gene in the Mut(s) recombinant strain was 2.7 fold of that in the Mut recombinant strain in the real-time PCR, and the expression of BmK AngM 1 in the Mut(s) recombinant strain was 1.5 fold of that in the Mut+ recombinant strain. Therefore, Mut(s) recombinant strain showed better ability to express BmK AngM1 than Mut+ recombinant strain.

Codon bias is an important factor which influences heterologous gene expression. Optimizing codon sequence could improve expression level of heterologous gene. In order to improve the expression level of BmK AngM1 gene encoding the analgesic peptide from Buthus martensii Karsch in Pichia pastoris, the codon-optimized BmK AngM1 gene according to its cDNA sequence and the preference codon usage of P. pastoris were cloned into expression vector pPIC9K and then transformed into P. pastoris. The expersion of recombinant BmK AngM1 (rBmK AngM1) was inducced by methanol in the medium, and the expression level of the optimized BmK AngM1 gene was 3.7 times of the native one. These results suggested that the expression of BmK AngM1 in P. pastoris could be successfully improved by codon optimization.

OBJECTIVE To strengthen the management of earthquake victims with nosocomial infection,in order to prevent and control the multidrug-resistance transmission,and the nosocomial infection outbreak. METHODS All 77 earthquake victims were under real-time monitoring. RESULTS Of 77 cases,53 were infected (69.74%). From 83 samples,83 pathogenic bacteria were isolated. The Gram-positive cocci were 19 (meticillin-resistant Staphylococcus aureus 3,Meticillin-resistant S. epidermidis 7),58 were Gram-negative bacilli (Acinetobacter baumannii 21,multi-drug resistant strains 10,ESBLs positive Escherichia coli 10,Pseudomonas aeruginosa 9) and the fungi were 6 strains,The resistance rates of Gram-positive cocci to penicillin,ampicillin/sulbactam and cefazolin were 89.47%,68.42% and 89.47%; the resistance rates of Gram-negative bacillis to imipenem,cefoperazone/sulbactam,piperacillin/tazobactam,azithromycin,tobramycin,and cefoxitin were 37.93%,60.34%,48.83%,98.28%,98.28% and 70.69%,respectively. CONCLUSIONS Under the situation of higher infection rate and a serious drug resistance in earthquake area,there are no multidrug-resistance transmissionm and the spread of nosocomiol infection outbreak happened in hospital due to strictly enforced prevention meassures and access real-time monitoring and management,

Objective Incontinence-associated dermatitis(IAD) is a common skin disease, but there is still lack of evidence on which kind of skin proctectant can provide effective prevention and cost reduction. The article aimed to explore the clinical effect and cost-effectiveness of two skin protectants based on structured skin care regimens in the nursing care of incontinent patients and provide evidence for effective prevention of IAD.Methods A total of 124 patients with incontinence were randomly selected and divided into observation group (62 cases) and control group (62 cases). On the basis of the structured skin care program which focused on incontinence management, cleansing and protection, the patients in the observation group were treated with the composite zinc oxide ointment for 7 days, while patients in control group were treated with ostomy powder combined with skin barrier film for 7 days. The main observation indicators were the incidence of IAD and the cost of nursing materials.Results All 62 patients in the observation group completed the study, while in the control group 2 patients fell off because of death and discharge from hospital and 60 patients completed the study. The per-protocol analysis showed that the incidences of IAD in two groups were 6.45% and 20.00%, the intention-to-treat analysis showed 6.45% and 22.58%, and there was significant difference between groups (P<0.05). The nursing cost of the observation group (239.71±48.55) was lower than that of control group (264.35±61.55), and the difference was statistically significant (P<0.05).Conclusion The use of the composite zinc oxide ointment based on a structured skin care regimen can improve the preventive effect of IAD and reducing costs.

OBJECTIVE: To evaluate the role of MHC II expression in posttrauma immune disturbances and infections. METHODS: In experimental study, peritoneal macrophages were harvested from traumatized mice and treated with GM-CSF, Ia molecules were determined by flow cytometry. In 24 trauma patients, monocyte HLA-DR expression was measured by APAAP technique. RESULTS: Marked inhibition of MHC II molecule expression was found in both traumatized mice and patients. In traumatic patients with infection, the inhibition was more severe. Treatment with GM-CSF in mice partially restored the Ia expression. CONCLUSIONS: Inhibition of MHC II molecules plays an important role in postrauma immune disturbances. There is a close relationship between HLA-DR inhibition and clinical infections.

Dural ateriovenous fistula (DAVF) at the craniocervical junction is rare. We report a patient presenting with brainstem dysfunction as an uncommon onset. Brainstem lesion was suggested by magnetic resonance image study. Angiogram revealed a DAVF at a high cervical segment supplied by the meningeal branch of the right vertebral artery, with ascending and descending venous drainage. Complete obliteration of the fistula was achieved via transarterial Onyx embolization. Clinical cure was achieved in the follow-up period; meanwhile, imaging abnormalities of this case disappeared. Accordingly, we hypothesize that a brainstem lesion of this case was caused by craniocervical DAVF, which induced venous hypertension. Thus, venous drainage patterns should be paid attention to because they are important for diagnosis and theraputic strategy.
