ObjectiveTo investigate the association between the common variant rs1512268 single nucleotide polymorphism(SNP) of NKX3.1 gene and the risk of prostate cancer,and to explore its interaction with related risk factors.MethodsTotally 122 patients with prostate cancer and 105 age matched male people (prostatic specific antigen ＜ 4 μg/L,without family history of prostate cancer) as control group were enrolled.Polymerase chain reaction - high resolution melting curve(PCR - HRM) combined with gene sequencing methods were used to determine the distribution of allele and genotype frequencies of the rs1512268 SNP.ResultsThe distributions of GG,AG,AA genotypes were 42 cases(33.4％),66 cases(54.1％),14 cases(11.5％) in patients with prostate cancer,and 45 cases(42.9％),51 cases(48.6％),9 cases(8.6％) in healthy control,respectively.There were no significant differences in the distribution of genotype(x2 =1.70,0.69,0.52) and allele frequency (x2 =1.575) between the two groups(P＞ 0.05).The different genotypes of rs1512268 of NKX3.1 gene were not associated with age,Gleason score,PSA levels and clinical stage of prostate cancer (P＞0.05). Conclusions rs1512268 SNP of NKX3.1 gene is not obviously associated with prostate cancer and may be not the genetic risk factor in Chinese.

Hirudin (HV) is known as the most potent and specific inhibitor of thrombin. Although hirudin has many advantages , it has the bleeding side effect and this is the great shortage of hiudin for clinical application. In order to alleviate bleeding side effect of hirudin, fusion protein, named as FHV (fusion hirudin linked with FXa recognition peptide) was designed. The fusion protein gene ( fhv) was cloned into plasmid pPIC9K. FHV engineered Pichia pastoris containing high copies was chosen for fermentation and purification at 30 L fermentor scale, finally, FHV with purity of above 97% was obtained. To investigate the function of FHV in vivo, mouse tail thrombosis model was used. In the mice thrombus tail model induced by carrageenan, FHV decreased the length of tail thrombus significantly, similar to that of HV control, and had no obvious effects on the TT, PT and APTT. In conclusion, FHV is constructed and expressed in yeast. FHV fusion proteins is obtained by fermentation and purification. FHV has antithrombotic effects not influencing IT, PT and APTT after administration immediately in animal models. Therefore, FHV is a promising anticoagulant and antithrombotic drug.

Objective:To investigate the impact of aging on the correlation between the intestinal microorganism Akkermansia and obesity, and to analyze the features of the correlation in the elderly population. Methods:This was a cross-sectional study.A total of 6896 cases were collected from the Guangdong intestinal microbiome in 2018, aged 18-94 years old, including 3806 females, 1641 cases with abdominal obesity(23.7%)and 707 cases with systemic obesity(10.3%). The 16S rRNA sequencing data were from individuals of Cantonese descent.The abundance of Akkermansia was calculated after data cleaning, clustering and annotation.The type of abdominal obesity or systemic obesity was diagnosed based on the standards of the Working Group on Obesity in China(2002). According to the five quintiles of the abundance of Akkermansia, subjects were divided into Q1~Q5(Q1-Q4: n=1379, Q5: n=1380). Logistic regression was used to study the relationship between Akkermansia and obesity after adjusting for common confoundors such as gender.Subjects were subgrouped into two types of age groups: the <65 group(n=5467)and the ≥65 group(n=1519); the <70 group(n=6136)and the ≥70 group(n=850). Age windows were used to analyze changes in characteristics of this relationship with increasing age. Results:There were significant differences in age and gender among different Akkermansia groups( t/ χ2=3.51, -5.03, P<0.01). Logistic regression analysis showed that after adjusting for two main confounding factors, age and gender, the risk of systemic obesity and abdominal obesity gradually decreased from Q2 to Q5 group, compared with Q1 group( P<0.001). The correlation between Akkermansia and obesity decreased with age.The protective effect of Akkermansia on obesity was weaker in the ≥65 and ≥70 groups, respectively, than in the <65 and <70 groups. Conclusions:Akkermansia is a protective factor for obesity, but the protective effect is affected by aging and weakened in the elderly.

OBJECTIVETo compare the differences in the clinical function and lumbar and abdominal myodynamia in patiants of lumbar disc herniation treated with moxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and acupuncture.

METHODSForty cases were randomized into a moxibustion group and an acupuncture group, 20 cases in each group. In the moxibustion group, the warm moxibustion was applied alternatively at Dazhui (GV 14) and Guanyuan (CV 4) once every other day, 1 h each time, once every day. In the acupuncture group, acupuncture was applied to the corresponding acupoints based on the affected lumbar vertebras, such as Jiaji (EX-B 2), Shens-hu (BL 23), Dachangshu (BL 25) and Huantiao (GB 30), etc. , once evey day 30 min each time. The treatment for 3 weeks was taken as one session in each group. Totally, one session treatment was required. Surface electromyography (SEMG) of bilateral paraspinal muscle and rectus muscle, and JOA score of low back pain were observed in the two groups.

RESULTS(1) JOA score: the score of subjective symptoms, score of activity of daily living (ADL) and total score were improved obviously as compared with those before treatment in the two groups (P<0.01, P<0.05). The results of subjective symptoms score, score of ADL and total score in the acupuncture group were superior to those in the moxibustion group after treatment (6.95+/-0.94 vs 5.50 +/-0.89,10. 90+/-1.86 vs 8.90+/- 1. 92,22.50 +/- 2.82 vs 19.35 +/- 2. 70, all P<0. 05). (2) SEMG comparison: root-mean-square value (RMS) was all reduced in SEMG of the anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle as compared with those before treatment in the two groups (P< 0.05, P<0. 01). RMS of the anteflexion and bilateral bending in the acupunture group were reduced much obviously as compared with the moxibustion group. In terms of sitting position anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle, median frequency (MF) after treatment was all improved as compared with that before treatment in the two groups (P<0. 05, P<0. 01). In terms of anteflexion, the electrode MF after treatment was improved much obviously in the acupuncture group(P<0. 05).

CONCLUSIONMoxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and conventional acupuncture all improve muscle function, relieve muscle fatigue, increase the ability of anti-muscle fatigue, strengthen lumbar vertebral stability, release subjective symptoms and improve ADL. But, the effects of moxibustion are slightly lower than those of acupuncture.

Objective To explore the correlation between ITGA6 gene (rs12621278, G), MSMB gene (rs10993994, T), chromosome 8q24 (rs10086908, T) and prostate cancer (PCa) in Beijing residents, and to explore the correlation between genotype and phenotype in PCa patients. Methods PCa patient phenotypes were collected including clinical, genetic, dietary habits, hobbies and blood samples. ITGA6 gene (rs12621278, G), chromosome 8q24 (rs10086908, T) and MSMB gene (rs10993994, T) compared the allele distribution between 112 PCa and 91 healthy control age matched patients. The genotype and phenotype analysis was conducted in the 2 groups. Results Between the case and control groups, only rs10993994, T of MSMB gene (case 56.4%,control 46.2%) was significantly different (P=0.001; OR=1.97, 95%CI:1.28-3.04). The rs10086908, T of 8q24 (case 83.5%, control 79.2%) and rs12621278, G of ITGA6 gene (case 27.2%, control 27.0%) were not significantly associated with PCa in the study sample (P>0.05). Quantitative trait analysis showed that the disease duration of ITGA6 risk genotypes (G/G,1.40±0.55 years) in PCa patients was significantly shorter (P=0.003) than the other genotype carriers (A/G, 4.38±3.10 years; A/A, 2.37±1.84 years). Conclusion The genetic variation in MSMB is possibly associated with PCa susceptibility, suggesting that MSMB genes might be associated with PCa in a Chinese population.

OBJECTIVETo investigate the prevalence of viral infections and putative association of viral infection with illness severity in young children with severe lower respiratory tract infection (LRTI) in Chongqing.

METHODRespiratory secretion specimens were collected from 119 hospitalized patients with severe pneumonia from December 2006 to March 2008.After being processed, the samples were detected for respiratory viruses including respiratory syncytial virus (RSV), adenovirus (ADV), human metapneumovirus (hMPV), human bocavirus (HBoV), parainfluenza virus 1, 2, 3 (PIV 1, 2, 3), influenza virus A and B (IVA and IVB) either by PCR or RT-PCR. Clinical data were analyzed along with virological data by using appropriate statistical methods.

RESULTViral pathogens were identified in specimens of 86 (72.3%) cases, among which RSV was detected in 49 (41.2%) patients. More than one virus was detected in 23 individual (26.7%) samples, of which 19 were dual positive for RSV and another virus. Bacterial cultures were performed for 69 patients. Both bacterial and viral pathogens were identified in 53 (76.8%) patients. Bacterial and viral coinfection was demonstrated in samples from 41 (59.4%) cases.

CONCLUSIONViral pathogens are the main etiology of severe pneumonia in young children in Chongqing area during the study period. RSV was the most frequent viral pathogens, followed by ADV and hMPV. Coinfection with respiratory common viruses was relatively common, though co-infection with viruses did not appear to aggravate the patients' condition.

AIM:To understand the clinic effect of intravitreal anti-vascular endothelial growth factor(VEGF) drugs injection in the treatment of fundus disease in the real-world study (RWS).METHODS:The clinical cases treated with anti-VEGF drugs in our department from September 2012 to June 2015 were enrolled in this study.Retrospective investigation was reviewed to the kinds of diseases, frequency, usage, efficacy, adverse reaction, and the effects on visual acuity, fundus and macular thickness which were treated with intravitreal anti-VEGF drugs injection.RESULTS:In 305 patients (340 eyes) treated with anti-VEGF drugs, 53 patients (60 eyes, 17.6%) were wet age-related macular degeneration (AMD), polypoidal choroidal vasculopathy (PCV) 16 cases (18 eyes, 5.3%), diabetic macular edema (DME) 120 cases (134 eyes, 39.4%), branch retinal vein occlusion (BRVO) secondary macular edema 61 cases (68 eyes, 20.0%), central retinal vein occlusion (CRVO) secondary macular edema 29 cases (32 eyes, 9.4%), idiopathic choroidal neovascularization (ICNV) 16 cases (18 eyes, 5.3%), high myopia with choroid neovascularization 4 cases (4 eyes, 1.2%), neovascular glaucoma 4 cases (4 eyes, 1.2%), retinal angiomatous proliferation (RAP) 1 cases (1 eyes, 0.2%) and optic papillary neovascularization 1 cases (1 eyes, 0.2%).The minimum age was 16 years old, and the maximum age 90 years old.There were 247 cases (275 eyes, 80.9%) were treated with intravitreal ranibizumab injection, 58 cases (65 eyes, 19.1%) intravitreal conbercept injection.The time number of all patients accepted anti-VEGF drugs treatment was 465, with an average of 1.7 times per eye.Which, the 3 + PRN treatment method in 98 patients (109 eyes, 32.1%), 1 + PRN treatment in 207 patients (231 eyes, 67.9%).69 cases (77 eyes, 22.6%) were used alone to receive anti-VEGF drugs therapy, 10 cases (11 eyes, 3.2%) combined with intravitreal triamcinolone injection(TA), 35 cases (39 eyes, 11.5%) combined with vitrectomy, 26 cases (29 eyes, 8.5%) combined with photodynamic treatment (PDT), 165 cases (184 eyes, 54.1%) combined with simple laser treatment.After anti-VEGF drug treatment, majority of patients' the best corrected visual acuity (BCVA), fundus and central macular thickness(CMT) were significantly improved, compared with the pre-treatment, the difference is significant (P<0.05).So that anti-VEGF drugs can effectively improve visual function and ocular fundus for fundus diseses.There were no serious adverse reactions except 3 patients appearling skin redness, itching, rash, 1 patient low low-grade fever and 1 patient acute cerebral infarction during the treatment.CONCLUSION:Intravitreal anti-VEGF drugs injection can significantly improve the visual function and ocular fundus for patients with fundus diseases, but there are still some adverse events, which should be attached great importance to medical workers.

OBJECTIVETo investigate the dynamic changes of plasma tissue factor (TF) and tissue factor pathway inhibitor-1 (TFPI-1) and their significance in patients with multiple traumas.

METHODSThe plasma levels of TF, TFPI-1 and D-dimer were detected using enzyme-linked immunosorbent assay in patients on the first, second and third days after multiple traumas, with 25 healthy adults as the normal control.

RESULTSThe levels of plasma TF and D-dimer increased on the first day, and reached the peak value on the second day, but TFPI-1 decreased with the passage of time. Significant differences were found in the levels of plasma TF between the multiple trauma patients (on the first, second, third posttrauma days) and the control group (P<0.01). Significant differences were also found in plasma TFPI-1 and D-dimer between the patients (on the second and third posttrauma days) and the control group (P<0.05).

CONCLUSIONCoagulation dysfunction and secondary fibrinolysis occur in the early stage of multiple traumas. Dynamic detection of plasma TF, TFPI and D-dimer is beneficial for understanding the degree of diffuse intravascular coagulation and inflammation after the trauma and can be used as the reference indexes for clinical diagnosis and therapy.

OBJECTIVETo investigate the expression of Csk-binding protein (CBP) in esophageal carcinoma and its association with the tumorigenesis and progression of esophageal cancer.

METHODSRT-PCR and Western blotting were employed to determine the expressions of CBP at the mRNA and protein levels in 50 pairs of fresh esophageal carcinoma tissue and the adjacent normal tissues.

RESULTSCBP mRNA and protein expressions in normal tissues were 1.43- and 1.28-fold higher than those in the cancer tissues, respectively (P<0.05). The expressions of CBP mRNA and protein were positively correlated (P=0.015). The decreased expressions of CBP were significantly correlated to lymph node metastasis of esophageal cancer (P<0.05).

CONCLUSIONThe expression of CBP gene is decreased in esophageal carcinoma, which might contribute to the tumorigenesis and progression of this malignancy.
