Objective The effects of AM fungi on the growth of Bupleurum chinense were investigated by inoculation Glomus mosseae, G. caledonium, and the two fungal mixture under different phosphorus levels. Methods Pot culture and experimental analyses were carried out. Results Mycorrhizal infection rate could be promoted by inoculation and increased phosphorus content of plant and root dry weight; the content of chlorophyll, carotenoids, and soluble sugar of leaf was higher than that of controlled plant, and the soluble sugar content of plant root by inoculation the two fungal mixtures were lower than that of controlled plant. The inoculation effect of AM fungi was closed related to AM fungal species and phosphorus applied levels, which was the best under 0.1—0.3 g/kg P_2O_5 soil. Conclusion The growth of host plant and using rate of phosphorus fertilizer can be promoted by inoculation of AM fungi.

OBJECTIVE To investigate the significance of diagnosis of tempanosclerosis by HRCT combined with pure tone audiometry. METHODS 176 patients(181 ears) with chronic suppurative otitis media in stationary phase were recruited in Guizhou Medical University Affiliated Hospital between January 2014 to December 2015. Temporal bone HRCT combined with pure tone audiometry were applied to all patients before operation to diagnose tempanosclerosis. Intraoperative exploration results was the gold standard to observe sensitivity, specificity, positive likelihood ratio and the difference of accuracy of two diagnostic methods. RESULTS 1. The sensitivity, specificity, positive likelihood, negative likelihood ratio and accuracy of tympanosclerosis diagnosed only by temporal bone HRCT were 58.55%, 93.10%, 8.49, 0.46 and 64.09% respectively. 2. The sensitivity, specificity, positive likelihood, negative likelihood ratio and accuracy of tympanosclerosis diagnosed by HRCT combined with pure tone audiometry were caculated as 94.08%, 89.66%, 9.09, 0.01 and 93.37% respectively. Type I diagnostic accordance rate was 89.66%, type II was 87.50%, type III was 84.62%and type IV was 82.14%. The total diagnosis coincidence rate was 86.18%. The diagnostic efficacy increased significantly by the combined method than by the temporal bone HRCT alone. CONCLUSION Temporal bone HRCT combined with pure tone audiometry is valuable in diagnosis of tympanosclerosis. It can provide theoretical basis for making optimal operation scheme in suspect tympanosclerosis patients.

Objective To evaluate the diagnosis and efficiency of nasal endoscopic surgery treatment for rhinogenous optic function damage (ROFD).Methods The clinical data of 36 patients (36eyes) with ROFD were retrospectively reviewed.All patients were operated on nasal sinus probing and open sinus surgery through transnasal endoscopic approach,and 10 patients underwent endoscopic optic nerve decompression.Results Seven patients had bilateral pansinusitis,9 patients had unilateral posterior ethmoidal sinusitis and sphenoiditis,8 patients had isolated sphenoiditis,8 patients had fungal sinusitis occured in the sphenoid sinus and unilateral posterior ethmoid sinus,3 patients had unilateral pyocyst and cyst of the sphenoid and ethmoid sinus,1 patient had frontal and ethmoidal sinusitis.All patients were confiemed by pathology after surgery.The visual acuity preoperative were as follows:3 eyes no light perception,10 eyes hand movement,11 eyes fingers counting less than 20 cm and 12 eyes were vision impaired in different degree.The visual acuity postoperative were as follows:3 eyes failed,13 eyes cured,20eyes improved from hand movement or fingers counting to fingers counting (30-60 cm).The efficiency rate was 91.7％(33/36).The other eye symptom was disappeared.Sinus epithelization was happened after surgery in all patients.Conclusions If the medicine expectant treatment is invalid,nasal sinus probing and open sinus surgery through transnasal endoscopic approach should be performed early in treatment of ROFD.Patients who suffered frnm severe visual damage and either unresponsive or intolerant to medical treatment should be administrated endoscopic sinus surgery including endoscopic optic nerve decompression.

Objective To investigate the process of apoptosis in lungs and liver induced by crushing hindlimbs of rat, and study the mechanismof crush injury. Methods The rat experimental model of hindlimbs crush injury was established. The cell apoptosis in lungs and liver was detected by TUNEL assay, and the expression of Bax, Bcl-2 and caspase-3 apoptin was examined by immunohistochemistry. Results C ompared with the control group, the partial muscle injury of rat’s hindlimbs was more serious with more apoptosis observed in lungs and liver (P<0.05). The expression of Bax was up-regulated and Bcl-2 was down-regulated, whereas caspase-3 expression was activated (P<0.05). Conclusion The cell apoptosis has increased significantly in lungs and liver after crush injury of hindlimbs in rat. The corre-lation factor released during tissue injury may mediate apoptosis process.

Objective To explore the risk factors of local relapse and distant metastasis after radical resection of lung adenocarcinoma.Methods A total of 102 patients with lung adenocarcinoma operated in First Affiliated Hospital of Xinjiang Medical University from January 2005 to January 2010 were collected.The correlation between clinicopathological characteristics and prognosis was evaluated by single-factor and multi-factor analyses.The survival curves were plotted using Kaplan-Meier.Single-factor analysis of statistical difference was tested using Log-rank test.Multi-factor analysis of prognostic factors were produced by COX regression proportional hazards model.Results In the whole group,1,2,3 and 5 year disease-free survival rates were 74.30％,58.00％,51.50％ and 44.90％ respectively,and the median disease-free survival was 30 months.Single-factor analysis showed that tumor size (x2 =9.951,P =0.002),clinical type (x2 =8.460,P =0.004),differentiated degree (x2 =4.807,P =0.028),lymph node metastasis (x2 =40.516,P =0.000),pathological stage (x2 =38.769,P =0.000) were prognostic factors for local relapse and distant metastasis in postoperative patients with lung adenocarcinoma.Muti-factor analysis showed that tumor size (OR =1.943,95 ％ CI:1.091-3.463,x2 =5.082,P =0.024),differentiated degree (OR =2.570,95 ％ CI:1.451-4.552,x2 =10.467,P =0.001),lymph node metastasis (OR =3.196,95％ CI:1.037-9.849,x2 =4.096,P =0.043) were independent prognostic factors for local relapse and distant metastasis in postoperative patients with lung adenocarcinoma.Conclusion Tumor size,differentiated degree and lymph node metastasis are independent prognostic factors for local relapse and distant metastasis in postoperative patients with lung adenocarcinoma.

Objective To investigate whether echocardiography left ventricular ejection fraction (LVEF) and NT-proBNP could be an early detective marker for patients with untypical NSTE-ACS. Methods A total of 248 ACS cases admitted to the emergency department of our hospital from January 1,2015 to June 31,2016 were retrospectively reviewed. The data included age,gender,past medical history,D-dimer,MB isoenzyme of creatine kinase(CK-MB),cardiac troponin I(cTnI),the precursor of the N-terminal pro-brain natriuretic peptide(NT-proBNP),electrocardiogram(ECG)before treatment,and the CK-MB,cTnI and LVEF,the treatment of percuta-neous coronary intervention(PCI)or thrombolytic by drugs. Survival condition and time from onset to death were recorded. According to the results of multivariate logistic regression analysis ,receiver operating characteristic curve(ROC curve)and fitting curve were drawn. The association between the LVEF and NT-proBNP before the treatment and prognosis of ACS was analyzed. Results NSTE-ACS patients with chief complaint of chest pain were less than those of STE-ACS(33.6% vs. 70.1%,P=0.003). Pre-hospital time was longer than that of STE-ACS group(67.92 ± 116.89 vs. 30.65 ± 55.59,P = 0.006). CTNI(4.37 ± 12.53 vs. 9.62 ± 18.00,P=0.011)and LVEF(53.51 ± 14.51 vs. 56.26 ± 12.30,P=0.019)were less than that of the STE-ACS group. NT-proBNP was higher than that of the STE-ACS group(2288.37 ± 4612.10 vs. 1506.84 ± 1722.51,P=0.038). mortality rates was higher than the STE-ACS group((15.3%vs. 6.8%,P=0.036). Multivariate logistic regression analysis showed that LVEF values was correlated to 28-day death(B =-0.097 ,P=0.022). The ROC curves showed that LVEF values was negative correlated with the 28-day death. However,combination of LVEF and NT-proBNP was better than single LVEF values. LVEF values was negative correlated with the NT-proBNP(r =-0.263,P=0.001), LVEF values had greater and longer survival time(B=0.401,P=0.045)but NT-proBNP was not related to surviv-al time.(B=0.00,P=0.931). Conclusion LVEF and NT-proBNP are correlated with the early risk assessment of patients with ACS,but was not correlated with the time from onset to death. The decrease in LVEF values at the early stage of NSTE-ACS may be helpful to indicate the critical condition of the ACS patients.

Objective To investigate the influence of kaempferol on transforming growth factor(TGF)-β1/Smads signal trans-duction in liver tissue of mice with schistosomiasis liver fibrosis. Methods Forty BALB/c mice were randomly divided into a normal control group(8 mice),a praziquantel group(8 mice ),and 4 praziquantel+kaempferol groups with different kaempfer-ol dosages(5,10,15,20 mg/kg respectively,6 mice each group). Besides the normal control group,all the mice in the other 5 groups were infected with Schistosoma japonicum. After the infection for 6 weeks,the praziquantel group and the 4 praziquantel+ kaempferol groups were treated with praziquantel 500 mg/(kg · d) for 2 d,then the mice in the praziquantel group were drenched with normal saline for 6 weeks,and those in the 4 praziquantel+kaempferol groups were drenched with kaempferol 5, 10,15,20 mg/kg respectively for 6 weeks. After the treatment,all the animals were sacrificed by the cervical dislocation meth-od,and the area of egg granuloma and the degree of fibrosis in the livers of the mice were observed by HE and Masson staining. The expressions of TGF-β1,Smad2/3,Smad7 proteins were measured by the immunohistochemical method,and the mRNA lev-els of the 3 proteins were detected by RT-PCR. Results Compared with the mice in the praziquantel group,the areas of egg granuloma of the liver of the mice in the 4 praziquantel+kaempferol groups were smaller,and the degrees of the hepatic fibrosis of the mice were lesser,and their expressions of Smad2 and Smad3 at protein and their mRNA levels were significantly lower (all P<0.05),while the expression of Smad7 at protein and its mRNA level were significantly higher(all P<0.05). Conclu-sion By decreasing the expressions of TGF-β1 and Smad2/3,and increasing the expression of Smad7,kaempferol can signifi-cantly reduce the degrees of hepatic fibrosis and granuloma caused by schistosome eggs after the praziquantel treatment.
