Objective To observe the inhibitory effects of Typhonium Giganteum soft capsules on tumor growth in Hep-2 tumor-bearing nude mice and its effects on the expression of tumor suppressor p53 gene; To discuss its mechanism of action.Methods Human liver cancer Hep-2 cell suspension back subcutaneous vaccination was conducted to prepare tumor models. BALB/c nude mice were randomly divided into model group, cisplatinum group, and TCM high-, medium-, and low-dose groups. Each group was given relevant medicine for gavage, once a day for 21 days. Growth changes of tumor volume were monitored; HE staining was used to observe pathological changes of tumor tissues; RT-PCR was used to detect the expression of p53 gene in tumor tissue of Hep-2 nude mice.Results Compared with the model group, all medication groups could inhibit the tumor growth, and the anti-tumor rates were 55.1%, 42.8%, 30.1%, and 79.5%, respectively; the expression of p53 gene increased; pathological observation results showed that the number and the volume of tumor cells increased, with cytoplasm rarefaction and nucleus anachromasis. All medication groups had karyopyknosis, slight staining, and decreasing blood capillary and focal necrosis in varying degrees.ConclusionTyphonium Giganteum soft capsules can inhibit the growth of human liver cancer, and its mechanism may be associated with the up-regulating expression of p53 gene leading to apoptosis.

We detected the seroprevalence of Toxoplasma gondii (T.gondii) in the wild birds in northeast China.The wild bird's blood was collected from the cutaneous ulnar vein and the serum was isolated and used for detection of anti T.gondii antibody by modified agglutination test (MAT).Results showed that totally 179 birds' serum samples were collected.Twenty serum samples (11.17％) were positive with T.gondii antibody,which belonged to 9 orders,17 families and 31 species.The seroprevalence against T.gondii was about 5.26％ (1/19) in Columbiformes,9.09％ (9/99) in Passeriformes,14.29％ (3/21) in Falconiformes,15.00％ (5/22) in Piciformes,16.67％ (1/6) in Coraciiformes,and 25.00％ (1/4) in Anseriformes.Based on their feeding behavior,the seroprevalence was 12.00％ (3/25) in carnivorous wild birds,10.60％ (15/141) in omnivorous wild birds,and 15.38％ (2/13) in the wild birds feeding on aquatic animals or plants.These wild birds also can be sorted as migratory and sedentary (non-migratory) according to their migration habits,and the serum positivity was 11.67％ (14/120),and 10.71％ (6/59) respectively.The seroprevalence against Toxoplasma gondii in wild birds in northeast China is about 11.17％,which indicates a common infection of Toxoplasma gondii in wild birds.

Objective To study the risk factors and prognosis of very/extremely low birth weight preterm (VLBW/ELBW) infants with bronchopulmonary dysplasia (BPD) during the first three years of life.Method From January 1st to December 31st,2012,a retrospective study was conducted on the VLBW/ELBW preterm infants with ＞ 28 days of hospitalization in the NICU of our hospital.The infants were assigned into BPD group (FiO2 ＞ 21％) and non-BPD group depending on the oxygen requirement on the 28th day after birth.The incidences of bronchitis,pneumonia,wheezing and re-hospitalization during the first three years of life were analyzed.The pulmonary function tests were performed at one-year-age.Independent-sapmles t test,Kruskal-wallis test and x2 test were used to compare the results between the two groups.Result A total of 72 patients were enrolled into this study.34 patients in the BPD group and 38 in the non-BPD group.The gestational age,birth weight and the use of INSURE technique of BPD group were significantly lower than non-BPD group,while the duration of hospital stays were longer than non-BPD group (P ＜0.05).The ratio of male,neonatal respiratory distress syndrome (RDS),patent ductus arteriosus (PDA),intrauterine infection,mechanical ventilation,nosocomial infection and the inhalation of high concentrations of oxygen were significantly higher in BPD group than non-BPD group (P ＜ 0.05).Incidences of bronchitis and wheezing during 0 ～ 1,1 ～ 2 and 2 ～ 3 years of age in the BPD were significantly higher than non-BPD group,separately.No significant differences existed in the incidences of pneumonia and re-hospitalization between the two groups.Pulmonary function test showed that the respiratory rate (RR) and peak tidal expiratory flow in the BPD group were significantly higher than non-BPD group,while the tidal volume,peak expiratory time and peak expiratory volume were significantly lower in BPD group than non-BPD group (P ＜ 0.05).Conclusion BPD often occurs in preterm infants with gestational age less than 32 weeks.It may cause impaired pulmonary function,characterized by obstruction in small airway,and increases the risk of bronchitis and wheezing during the first three year of life.

Objective To investigate the clinical efficacy of TCM external treatment combined with Dasangju Mixture in treating mycoplasma pneumoniae pneumonia (MPP) in children. Methods One hundred patients with MPP were randomly divided into control group and treatment group by parallel design, with 50 patients in each group. Patients in control group orally took azithromycin combined with other symptomatic treatment when necessary, 7 d for a course and continuously for 3 courses. Based on the treatment for control group, patients in treatment group were added with TCM external treatment (BL13 and RN17) combined with Dasangju Mixture, while azithromycin was sequentially used just for 2 courses. Other types of treatment lasted for 3 courses. The improvement time of symptoms and signs of the patients were recorded and the therapeutic effects of the two groups were evaluated. Moreover, the serum concentrations of mycoplasma pneumoniae-immune gloulin M (MP-IgM) were determined before and after treatment on the 1st and 21st days. Results The improvent time of fever, and cough and lung sign of the treatment group were more obviously shortened than the control group (P<0.05). The total effective rate was 96.0% (48/50) in observation group and 74.0% (37/50) in control group, with statistical significant difference between the two groups (P<0.05). After treatment, the negative rate of the serum concentration of MP-IgM in the treatment group was 82%, and that of the control group was 58%, with statistical significance between the two groups (P<0.05).Conclusion TCM external treatment combined with Dasangju Mixture can not only significantly improve the clinical symptoms and signs of MPP children patients, but also shorten the disease course, and the efficacy was significant. Meanwhile it can reduce the course and side effects of azithromycin, which provides reference to the administration of antibiotics in children.

BACKGROUND:More recently, studies have demonstrated that bone marrow mesenchymal stem cel s can be induced in vitro to differentiate into neuron-like cel s that are used for in vivo transplantation to repair nerve damage.
OBJECTIVE:To study the effect of bone marrow mesenchymal stem cel transplantation on learning and memory ability of senile dementia rats.
METHODS:Thirty male Sprague-Dawley rats were randomly divided into three groups:normal control group, stem cel therapy group and model control group. Rats in the latter two groups were used to establish animal models of senile dementia by intracranial injection ofβ-amyloid 1-40. Three weeks after modeling, rats were given bilateral hippocampal injection of induced bone marrow mesenchymal stem cel suspension in the stem cel therapy group, whereas no treatment was given in the normal control and model control groups. Morris water maze test was used to detect learning and memory ability of rats, and rat’s brain tissues were detected pathological y using hematoxylin-eosin staining.
RESULTS AND CONCLUSION:After modeling, the escape latency was higher and the cross-platform frequency was lower in the model control group compared with the normal control group. After cel transplantation, the escape latency and cross-platform frequency were gradual y shortened and increased with time, respectively. Compared with the model control group, the learning and memory abilities of rats were improved in the stem cel therapy group. The brain tissues were relatively intact in structure and exhibited less cel degeneration and necrosis in the stem cel therapy group compared with the model control group. To conclude, bone marrow mesenchymal stem cel transplantation exerts certain therapeutic effects on senile dementia by effectively improving the learning and memory ability.

Objective To establish biological reference intervals of neonatal T lymphocyte subsets and IgG, IgA,IgMlevels in 24 -hour newborns in Guangxi.Methods Maternal history and neonatal clinical data were evalua-ted and recorded.Venous blood samplings were collected within 24 hours of birth and were sent for testing in half an hour.The neonates were divided into the early -preterm,the late -preterm and the term neonates group,1 1 0 cases for each group.The parturients were divided into Dexamethasone treatment group and without Dexamethasone treatment group.Data in neonates and the parturients and the sex were analyzed by SPSS 1 7.0 software and the biological refe-rence values were calculated.Results The two -sided reference intervals of 95% in the early -preterm group,the late -preterm group and the term neonates group were as follows:CD3 +:52.07 -88.92 g/L,58.1 6 -90.42 g/L, 56.1 5 -95.67 g/L;CD4 +:25.20 -59.26 g/L,31 .27 -72.91 g/L,28.44 -82.66 g/L;CD8 +:7.30 -36.26 g/L, 9.1 3 -38.49 g/L,1 1 .09 -48.99 g/L;CD4 +/CD8 +:0.34 -4.58,0.34 -4.58,0.32 -3.80;CD1 9 +:3.95 -27.59 g/L,4.04 -30.94 g/L,4.08 -38.70 g/L;NK cell:1 .34 -6.64 g/L,2.88 -8.92 g/L,3.07 -9.35 g/L;IgA:0.000 4 -0.039 6 g/L,0.000 0 -0.069 0 g/L,0.000 0 -0.069 0 g/L;IgM:0.001 6 -0.1 58 4 g/L,0.020 0 -0.1 40 0 g/L,0.020 0 -0.420 0 g/L;IgG:3.22 -1 0.98 g/L,1 .1 0 -1 4.62 g/L,5.00 -1 3.66 g/L.Moreover the ca-ses with Dexamethasone treatment were as follows:the late -preterm infants CD8 + 1 0.35 -40.33 g/L,NK 3.1 0 -9.46 g/L,term NK 6.60 -9.50 g/L;those in without Dexamethasone treatment:the late -preterm infants CD8 +8.42 -34.96 g/L,NK 2.94 -7.80 g/L,term NK 2.98 -8.94 g/L;according to gender,the males in the late -pre-term infants CD8 + 8.26 -35.66 g/L,term CD3 + 51 .90 -92.94 g/L;females in the late -preterm infants CD8 +1 1 .08 -40.68 g/L,term CD3 + 61 .1 0 -96.1 4 g/L.Conclusions Testing values of neonatal T lymphocyte subsets and IgG,IgA,IgM levels in 24 -hour newborns in Guangxi disperse largely and show some differences among the early -preterm neonates,the late -preterm neonates and the term neonates,and maternal Dexamethasone treatment during pregnancy and gender play a role in neonatal immunity.

Objective To investigate the diagnostic correlation and sensitivity of amplitude integrated electroencephalogram (aEEG),brainstem auditory evoked potential (BAEP) and cranial magnetic resonance imaging (MRI) for acute bilirubin encephalopathy (ABE) in the newborn.Method Term and near-term neonates (gestational age ≥ 35 weeks) with hyperbilirubinemia (the level of bilirubin over than 95th percentile) of high and intermediate risk group admitted in the neonatal ward of Guangxi Maternal and Child Health Care Hospital from Jan 2014 to Dec 2015 were recruited retrospectively.The infants were assigned to ABE group and non-ABE group according to the diagnostic criteria of ABE.The clinical data of the newborns were collected and the diagnostic correlation between clinical diagnosis and aEEG,BAEP and cranial MRI were analyzed.The receiver operating characteristic (ROC) curve was adopted to assess the diagnostic efficiency of the peak level of serum bilirubin,aEEG,BAEP and cranial MRI on the early diagnosis of ABE.Result A total of 152 newborns with hyperbilirubinemia were recruited,including 33 cases in the ABE group and 119 cases in non-ABE group.(1) The results of aEEG and MRI were marginally positively correlated with clinical diagnosis of ABE (aEEG:r =0.487,P ＜ 0.001;MRI:r =0.220,P=0.018),while the results of BAEP were closely related to the clinical diagnosis of ABE (r =0.593,P ＜ 0.001);(2) The results of BAEP and MRI on the diagnosis of ABE were positively correlated with those of aEEG (BAEP:r =0.424,P ＜ 0.001;MRI:r =0.307,P ＜ 0.001).(3) The area under the ROC curves for predicting the onset of ABE were 0.899 for the peak level of serum bilirubin,0.767 for BAEP,0.738 for aEEG and 0.590 for MRI.Conclusion There was the correlation on the diagnosis of ABE among the methods of aEEG,BAEP and MRI.The combined diagnosis of the three methods could play a complementary role.The aEEG contributed to the early diagnosis of ABE with high sensitivity.

Objective To observe the effects of penetrance,different time of onset and mutation sites on retinal nerve fiber layer (RNFL) and macular thickness in patients with Leber's hereditary optic neuropathy (LHON).Methods This was a cross-sectional observational study.A total of 88 patients with LHON and 1492 relatives of the maternal relatives (gene carriers) who received treatment in People's Liberation Army General Hospital from 2015 to 2017 were included in the study.Among the 1492 family members,there were 694 males and 798 females.Peripheral venous blood was extracted from all subjects for mitochondrial DNA testing,and penetrance was calculated.A total of 117 patients underwent BCVA and SD-OCT examinations,including 82 patients and 35 gene carriers.The BCVA examination was performed using the Snellen visual acuity chart,which was converted into logMAR visual acuity.The thickness of RNFL,ganglion cell complex (GCC) and inner limiting membrane (ILM)-RPE were measured with OCT instrument.The mean follow-up was 50.02± 86.27 months.The disease course was divided into 6 stages including ≤3 months,4-6 months,7-12 months and ＞ 12 months.The thickness of RNFL,GCC and ILM-RPE in patients with different time of onset and mutation sites were comparatively analyzed by covariance analysis.Categorical variables were expressed as a percentage,and the x2 test was used for comparison among multiple groups.Results Among the 1492 family members,285 were diagnosed with LHON and highly suspected clinical manifestations (19.10％),including 190 males (21.98％) and 95 females (11.90％).The total penetrance rates of 11778,14484 and rare mutation sites were 19.84％ (228/1149),20.50％ (33/161),and 13.19％ (24/182) respectively;male penetrance rates were 28.87％ (153/530),27.28％ (20/72),and 18.48％ (17/92) and female penetrance rates were 12.12％ (75/619),14.61％ (13/89) and 7.78％ (7/90).There was no significant difference in total (x2=4.732),male (x2=4.263) and female (x2=4.263) penetrance between different mutation sites (P=0.094,0.110,0.349).Compared with non-pathogenic carriers,the thickness of the RNFL,GCC and ILM-RPE were all different in the four stages (≤3months,4-6 months,7-12 months and ＞12 months).The thickness ofRNFL,GCC and ILM-RPE decreased with the time of onset (P=0.000).There were significant differences in the thickness of each of the GCC and ILM-RPE layers in the macular area of LHON patients with different mutation sites (P＜ 0.05).Among them,the site 11778 and 3460 had the most severe damage in all quadrants of macular GCC and ILM-RPE layer,followed by 14484 site,and the rare site had the least damage in all quadrants.Conclusions The penetrance of LHON patients is 19.10％.With the extension of the onset time (within 1 year),the RNFL layer of the optic disc and all quadrants of the macular GCC and ILM-RPE layer gradually thinned.Compared with 11778 and rare site,14484 site,and the rare site had the lighter damage on the thickness of RNFL,GCC and ILM-RPE.
