This paper reports the effects of the temperature control freezing and the liquid nitrogen vapour freezing on the viability of rabbit morulae. After rapid thawing, 70.27% embryos were able to develope well in vitro in the temperature control freezing group and in the liquid nitrogen vapour freezing group, the developmental rate was 80.56% when the freezing medium contained higher concentration of glycerol. After synchronous embryos were transplanted, the birth rate was 13.64% and 13.33%, respectively, in both freezing groups, and 11.11% in the control group. The results indicate that both freezing methods have almost the same good results, but the method of liquid nitrogen vapour freezing is more useful than the temperature control freezing method in some aspects.

Objective To investigate the relationship between polymorphism of the estrogen receptor(ER) gene and bone mineral density(BMD), and bone metabolism in Chinese postmenopausal healthy women. Methods In 246 postmenopausal healthy women, aged 44-78 years (average 61 years), BMD of lumbar spine and femoral neck, Ward and trochanteric areas were measured by dual energy X ray absorptiometry. Biochemical indexes(serum Ca, P, ALP, PTH, CT)were measured and PvuⅡ and XbaⅠ restriction fragment length polymorphism(RFLP) of ER were analysed by polymerase chain reaction restriction fragment length polymorphism(PCR RFLP). The relationship between polymorphism of the ER gene and BMD, and bone metabolism were evaluated. The RFLP was represented as Pp(PvuⅡ) and Xx(XbaI). Results In the PPxx genotype, Z score values of BMD were significantly lower than those in other genotypes. Conclusion RFLP of ER gene associated with BMD in postmenopausal healthy women and this might explain the cause of postmenopausal osteoporosis in Chinese women.

Objective:To observe neurotransmitter changes of post cerebral infarction depression (PCID) before and after being treated with amitriptyline or acupuncture of Baihui,in order to explore a good way with a less toxicity and good effect of treatment on PCID.Methods:The 60 patients were divided into treatment group and control group.Besides the basic treatment,the treatment group was given acupuncture of Baihui (DV20) and point injection therapy,the control group was given amitriptyline. Both before and after treatment,compared the two groups with HAMD score,neurologic impairment score,plasma 5-HT and NE,and observed the adverse events and side effects.Results:The results of two groups in monoamine neurotransmitter 5-HT(5-HT),norepinephrine (NE) and the HAMD scale were significantly improved.Conclusion:Acupunture of Baihui and point injection of Herba Erigerontis had equal effect to the amitriptyline on PCID.Furthermore,it had fewer venenosus side effects.It provided a new way for the use of the traditional Chinese medicine in treating PICD.

A total of 206 patients of type 2 diabetes mellitus (T2DM) were assigned into the trial group (n =156) and the control group (n =50) according to whether real object-based diabetic diet was provided.Traditional nutritional education for both groups during hospitalization.The patients in the trial group received a real object-based diabetic diet guided by a nutritionist who adjusted feeding regimens and skills before and after operation.The control group had a free access to a normal diet.The patient understanding of knowledge,attitude and practice (KAP) was examined by nutrition surveys.And their postoperative nutrition states and complications were assessed by questionnaires during a 6-month follow-up.The total average score of cognitive divided was 93.4 ± 7.5,the average score of diet therapy knowledge 13.8 ± 1.6 and the average scores of attitude and practice 9.6 ± 1.9 and 32.2 ±3.9.Significant differences existed between two groups (P ＜ 0.05).The incidence rates of hypoglycemia,hyperglycemia and gastrointestinal obstruction were lower than the control group (P ＜ 0.05,P ＜ 0.01).It suggested that real object-based diabetic diet guidance plus traditional nutrition education could improve the KAP level and may lower the incidence of postoperative complications in T2DM patients with gastric bypass.

Objective To investigate β-lactamase gene and class 1 integron gene from 60 clinical Acinetobacter baumannii isolates.Methods The minimal inhibitory concentrations (MICs) for 16 antibiotics widely used were determined using the standard broth microdilution method.The β-lactamase gene,class 1 integron gene and adeB gene were determined by PCR and then sequenced.Results Fifty-three strains of the 60 A.baumanii isolates were multi-drug resistant.OXA-23 gene was detected positive in six A.baumanii isolates,which were all resistant to more than five antimicrobial agents including carbapenem and showed high resistance to many antibiotics.Thirtyeight strains earring PER-1 gene showed higher resistance to cephalosporins than those without this gene (P＜0.01).Class 1 integron gene was positive in 45 strains,which exhibited significantly higher multiple resistance than those without this gene (P＜0.01).Twenty-five strains carrying both class 1 integron and PER-1 genes had a markedly higher multiple resistance (P＜0.01),but not in resistant level,compared to the 7 strains without these two genes.Conclusion Class 1 integron and β-lactamase gene may be the causes of muhidrug-resistance of A.baumanii.The strains carrying OXA-23 gene always showed multiple and high resistance to several antibiotics,so effective measures must be taken to control the epidemic of these strains.

Objective To detect the expression of 84 signaling molecules associated with nuclear factor-κB in lesions of Uygur patients with psoriasis.Methods Skin specimens were obtained from the lesional and paralesional skin of eight Uygur patients with psoriasis.Total RNA was extracted from the skin specimens and reversely transcribed into cDNA.PCR-array analysis was carried out to quantify the expressions of 84 signaling molecules related to nuclear factor-κB.Genes with a fold-change ＞ or =2 were defined as differentially expressed.Results Among the 84 tested genes,22 showed upregulated expression,7 downregulated expression,and the remaining 54 genes showed no significant changes in psoriatic lesions compared with the normal skin.The strongest upregulation was observed in the gene expressions of Caspase recruitment domain family 11 (CARD11) and granulocyte-macrophage colony-stimulating factor 2 (CSF2),and the most significant downregulation in the gene expression of interleukin 10 (IL-10),tumor necrosis factor superfamily member 5 (CD40) and nuclear factor of kappa light polypeptide gene enhancer in B-cell inhibitor,epsilon (NFκBIE).Conclusion Multiple molecules involved in the NF-κB signaling pathway might be activated or inhibited in lesions of patients with psoriasis.

Objective To investigate the changes of cardiac structure and function in patients with hepatolenticular degeneration (HLD).Methods From March 2010 to February 2011,90 HLD patients who did not receive formal treatment (observation group) and 30 healthy people (control group) were collected and analyzed with color Doppler echocardiography in the Institute of Neurology,Affiliated Hospital of Anhui University of Traditional Chinese Medicine.Based on the clinical manifestations,cases were divided into hepatic type group (n =31),brain type group (n =42) and brain-visceral type group (n =17).According to the Child-Pugh classification,patients were divided into Child A group (n =71),Child B group (n =10) and Child C group (n =9).Results (1) The left atrial diameter ((28.00 ± 3.11),(29.62 ± 3.44) mm) and left ventricular diameter ((45.69 ± 3.75),(47.10-± 4.73) mm) of HLD patients in brain-visceral type group and hepatic type group were larger than that of the control group ((24.86 ± 2.63),(41.93 ±3.56) mm;t =3.143,4.761,P=0.018,0.000;t=3.764,5.167,P=0.018,0.000).The left atrial diameter and left ventricular diameter of hepatic type group were significantly larger than the brain type group (26.06 ± 3.68,43.34 ± 3.88;t =3.557,P =0.000;t =3.751,P =0.001).The value of E/A in the hepatic type group (1.57 ± 0.37) was significantly lower than the control group (1.93 ± 0.20;t =-0.352,P =0.006).(2) The left atrial diameter ((31.29 ± 1.70),(34.67 ± 1.97) mm) and left ventricular diameter ((48.29 ± 2.81),(53.67 ± 2.67) mm) of Child B and C groups were significantly larger than the control group ((24.86 ± 2.63),(41.93 ± 3.56) rm;t =6.429,9.810,P =0.000,0.000;t =6.357,10.738,P =0.000,0.000),and the Child A group ((26.42 ± 3.05),(43.89 ± 3.76) rm;t=4.871,8.252,P=0.000,0.000;t =4.399,8.780,P=0.003,0.000).The value of E/A of Child B and C groups (1.58 ± 0.32,1.26 ± 0.39) was lower than that of the control group (t =-0.347,0.662,P=0.020,0.000);At the same time,the value of E/A of Child C group was significantly lower than that of Child A group (1.80 ± 0.33;t =-0.530,P =0.000).Conclusions The HLD patients may have cardiac structural and functional changes,mainly manifested as left atrial and left ventricular enlargement and cardiac diastolic dysfunction,whereas a serious impact has not yet been found in systolic function.And the changes of cardiac structure and function were related to the degree of liver cirrhosis in patients with HLD.

ObjectiveTo investigate the current situation of intensive care unit (ICU) inpatients in Infectious Disease Hospital of Nanning to provide a reference for the prevention and control of infectious diseases and construction and development of ICU in such a hospital.Methods The clinical data of inpatients from January 2011 to December 2015 in the Infectious Disease Hospital Affiliated to Guangxi Medical University (that is the Fourth People's Hospital of Nanning City) were retrospectively analyzed, and the distributions of patients with various diseases, ages, of the characteristics of children severe infectious diseases in ICU, the numbers of patients with infectious diseases in general ward and ICU, the average time and daily cost of hospitalization and mortality were conducted.Results During 2011 to 2015, 855 cases in ICU were treated, including 709 cases of infectious diseases, 146 cases of non-infectious disease. The top 5 infectious diseases were ranked as follows: tuberculosis, human acquired immune deficiency syndrome (AIDS), hand-foot-mouth disease (HFMD), viral hepatitis, tetanus, accounting for 96.47% of the total infectious disease inpatients in ICU; there were 25 cases of other legal infectious diseases, accounting for 3.53%, including dengue fever, measles, malaria, chicken pox, mumps, rabies, typhoid fever, paratyphoid fever, scrub typhus, bacillary dysentery, leptospirosis, human infections with highly pathogenic H7N9 avian influenza, epidemic hemorrhagic fever, A H1N1 influenza, and besides, critically ill patients carrying virus (viral hepatitis B and AIDS) in 7 pregnant women, 22 surgical patients, and 117 patients with internal medicine diseases were also admitted and treated. The top 4 infectious diseases causing deaths in ICU were tuberculosis, AIDS, viral hepatitis and HFMD: The infectious diseases with top 6 high mortalities in ICU were as follows: rabies, viral hepatitis, AIDS, tuberculosis and tetanus. The age range was wide in this study, from 73 days to 97 years, among which there were 167 cases of pediatric infectious diseases from pediatric department, accounting for 23.55% of ICU inpatients, being mainly severe HFMD, tuberculosis and severe varicella. From 2011 to 2015, the number of hospitalized patients showed a rising trend, and the average length of stay of patients in general wards presented a downward tendency, but the average time of hospitalization of inpatients with infectious disease in ICU, mortality and daily cost of hospitalization revealed a gradually increasing trend year by year.Conclusions It is of far-reaching significance to master the spectrum of dangerous severe infectious diseases to deal with the infectious disease epidemic situation and outburst with public health events.

AIM: By studying the ultrastructure of organs (hearts, brains, lungs, livers, kidneys) and vascular endothelial cells, and changes of physiological and biochemical indexes with multiple organ dysfunction syndrome in the elderly rats, their signification and their developing rules were analyzed. METHODS: Wistar rats(Half of Wister rats were three-month-old and another half of twenty-month-old) were anaesthetized and dealt with cecal ligation puncture (CLP) operation. They were defined as MODSE group and MODSY group, respectively. They were perfused through all vascular circulation by 1% glutaric dialdehyde. These slices were observed under transmission electron microscopy. RESULTS: Physiological and biochemical indexes at 24 huor in elder rats were shown significant difference compared with the younger rats ( P
