Objective To discuss The Clinical Significance of Eosinophil (EOS) in urosepsis. Methods A total of 99 patients of urosepsis in Department of Urology,Guangdong Provincial TCM Hospital from Mar. 2013 to Jul. 2016 were selected as research objects by retrospective analysis. The patients were classified into groupEOS= 0 andgroup EOS > 0,group PCT(procalcitonin)≥ 2 ng/mL andgroup PCT < 2 ng/mL,the differences of PCT concentration and percentage of EOS in two groups were analyzed comparatively. 99 patients of urosepsiswere also compared the difference of the percentage of EOS with another group including 100 patients of urinary tract infection (UTI) without Sepsis. Results The percentage of EOS was significantly decreased in 86.9%(86/99)of patients of urosepsis. The paired student t test show the percentage of EOS in two days after treatment,four days after treatment, before hospital discharge were higher than that before the treatment, the difference wassignificant (P < 0.05). The Independent-Sample Test show that the PCTconcentration in EOS = 0 group were higher than EOS > 0 group,the percentage of EOS in PCT≥2 ng/mL groupwere lower than PCT<2 ng/mL group,difference were significant(P<0.05). And The Independent-Sample Testalso showed that the percentage of EOS of the Urosepsis group was definitely lower than the UTI group without Sepsis. Difference was statistically significant. Concusions The percentage of EOS could be applied to assess the severity of urosepsis, monitor the disease progression and evaluate the infection control. The cost was lower than PCT in therapeuticprocess ofurosepsis.

OBJECTIVETo explore the chaotic dynamic process of multiple organs dysfunction syndrome (MODS) and the regulatory effect of Shenqin Liquid (SQL), a Chinese herbal liquid preparation with the action of purging and qi-tonifying.

METHODSEighty SD rats were divided into 4 groups, and were given suspension of zymosan A and paraffine (1 mL/kg) by peritoneal injection except for those in the blank control group to set up the multiple organs dysfunction syndrome (MODS) model. Low and high doses SQL were administered twice at the doses of 30 and 60 g/kg of SQL respectively at an interval of 8 h per day before modeling. Serum concentration of tumor necrosis factor alpha (TNF-alpha) and nitric oxide (NO) in MODS model animals were tested diachronically, eg. 12, 6 h before modeling, during modeling, 6 and 12 h after modeling, and then the mathematic models were built up with compartment analysis. Lyapunov exponents (LE) of the mathematic models were calculated to evaluate their chaotic characteristics of movement and the degree of chaos was ascertained with the correlation dimension (CD).

RESULTSThe serum levels of TNF-alpha and NO were significantly higher than those in the bland control group at modeling, 6, and 12 h after modeling (P <0.01), while those in the low and high doses of SQL were significantly lower than the model group (P <0.01). Moreover, the level of NO in the high dose of SQL was significantly lower than that in the low dose group (P <0. 01). CD of TNF-alpha movement in the blank control group was 0.803 with the LE less than zero; those in the model group was 1. 966 and > 0 respectively; in the low dose and high dose SQL treated groups, CD was 0.517 and 0.653 respectively and LE >0. CD of NO movement in the blank control group was 0.670 and with LE < 0; in the model group, 1.242 with LE > 0; in the low dose SQL group, 0.574 and in the high dose SQL group 0.850, and LE <0 in the two groups.

CONCLUSIONUnder the normal physiologic condition, TNF-alpha and NO moved steadily without chaotic properties; while under the pathologic condition of MODS, they manifest relatively complicated chaotic properties. SQL can intervene the movement of TNF-alpha and NO, decrease the complexity of their chaotic movement, and make them return back to a stable state.

Objective To explore the risk factors of systemic inflammatory response syndrome crisis (SIRS) after percutaneous nephrolithotomy (PCNL) in China. Methods Databases of CNKI, CBM, WanFan and VIP were searched to retrieve studies about systemic inflammatory response syndrome after percutaneous nephrolithotomy to October, 2016. Results 18 studies involving 5,323 patients were included. The results of meta-analysis showed that:a) univariate analysis indicated that renal insufficiency [O(R) =2.78, 95%CI (1.96 to 3.95), P = 0.000], preoperative positive urine culture [O(R) = 3.41, 95%CI (1.89 to 6.15), P = 0.000], preoperative routine urine leucocyte positive [O(R) = 3.78, 95%CI (3.02 to 4.72), P = 0.000], diabetes mellitus [O(R) = 2.14, 95%CI (1.33 to 3.45), P = 0.002], pelvic positive urine culture [O(R)= 5.14, 95%CI (2.46 to 10.73), P = 0.000] and operation time ≥120 min [O(R) = 2.31, 95%CI (1.40 to 3.82), P = 0.001] were the risk factors of SIRS; b) multivariate analysis showed that, preoperative positive urine culture [O(R) = 6.83, 95%CI (2.82 to 16.57), P = 0.000], preoperative routine urine leucocyte positive [O(R) = 5.43, 95%CI (3.51 to 8.41), P = 0.000], diabetes mellitus [O(R) = 2.85, 95%CI (1.45 to 5.58), P = 0.002], pelvic positive urine culture [O(R) = 4.30, 95%CI (1.30 to 14.21), P = 0.020] and operation time ≥120 min [O(R) = 2.72, 95%CI (1.62 to 4.59), P = 0.000] were the independent risk factors of MCAT. Conclusion The independent risk factors of SIRS for patients after PCNL are diabetes mellitus, preoperative positive urine culture, preoperative routine urine leucocyte positive, pelvic positive urine culture and operation time. However, due to the quantity and low quality of the included literature, the conclusion needs the support from high quality studies.

OBJECTIVETo explore the patterns of Cx43 and Pax3 protein expressions in the small intestinal muscular layers of human embryo during early development.

METHODSImmunohistochemistry with SABC method was employed to examine the expression of Cx43 and Pax3 proteins in the muscular layers of the small intestine in early human embryos in the second to fourth months of gestation.

RESULTSIn the second month of gestation, the muscle layer of the small intestine was negative for Cx43 and Pax3 protein expressions. In the third month, Cx43 and Pax3 expressions were negative in the inner circular muscle layer, but some positive cells were found in the longitudinal muscle layer and the myenteric plexus. In the fourth month, positive expression of Cx43 and Pax3 proteins were seen in the entire muscle layer.

CONCLUSIONCx43 and Pax3 proteins are closely related to the growth and development of the cells and tissues in the small intestinal muscle layer in human embryos.

OBJECTIVETo investigate the protective effect of suppressive oligodeoxynucleotides (Sup ODN) on interferon-γ (IFN-γ) and signal transducers and activators of transcription (pSTAT4) expression of Silica-induced pulmonary inflammation in Mice.

METHODSSixty Balb/c mice were randomly divided into 4 groups, normal control group, silicious group, suppressive oligodeoxynucleotides (Sup ODN) group, control oligodeoxynucleotides (Con ODN) group. Except the normal control group injected normal saline, the rest groups were induced by the intratracheal instillation of 0.1 ml (5 g/L) of sterilized silica suspension. Sup ODN group and Con ODN group were treated by i.p. injection of 0.3 ml (1mg/mL) of suppressive or control ODN 3 h before silica administration. After 7 days, the animals were killed and levels of IFN-γ were detected by ELISA. The pathologic changes in lung tissues of mice were observed with HE staining. Expressions of IFN-γ and pSTAT4 in lung tissue were detected with immunohistochemistry and quantified by Image-Pro Plus 7.0.

RESULTSHE staining showed that the lung tissue of silicious group were damaged seriously than Sup ODN group. Compared with the normal control group (serum: (280.1±41.3) pg/ml, lung tissue: (0.249±0.373), IFN-γ increased in silicious group (serum: (886.3±81.7) pg/ml, lung tissue: (0.270±0.300) (P < 0.05). Compared with the normal control group and Con ODN group [(894.5±91.6) pg/ml], IFN-γ in the serum of Sup ODN group decreased significantly (P < 0.01). Compared with the silicious group , IFN-γ in lung tissue decreased in Sup ODN group (0.241±0.250) (P < 0.05). Compared with the normal control group (0.279±0.353), pSTAT4 in lung tissue increased significantly in silicious group (0.313±0.231) (P < 0.01). Compared with the silicious group, pSTAT4 in lung tissue decreased significantly in Sup ODN group (0.269±0.523) (P < 0.01).

CONCLUSIONSup ODN attained protective effect on Silica treated mice by suppressing expression of IFN-γ and pSTAT4.

Avian trichomoniasis caused by Trichomonas gallinae is a serious protozoan disease worldwide. The domestic pigeon (Columba livia domestica) is the main host for T. gallinae and plays an important role in the spread of the disease. Based on the internal transcribed spacers of nuclear ribosomal DNA of this parasite, a pair of primers (TgF2/TgR2) was designed and used to develop a PCR assay for the diagnosis of T. gallinae infection in domestic pigeons. This approach allowed the identification of T. gallinae, and no amplicons were produced when using DNA from other common avian pathogens. The minimum amount of DNA detectable by the specific PCR assay developed in this study was 15 pg. Clinical samples from Guangzhou, China, were examined using this PCR assay and a standard microscopy method, and their molecular characteristics were determined by phylogenetic analysis. All of the T. gallinae-positive samples detected by microscopic examination were also detected as positive by the PCR assay. Most of the samples identified as negative by microscopic examination were detected as T. gallinae positive by the PCR assay and were confirmed by sequencing. The positive samples of T. gallinae collected from Guangzhou, China, were identified as T. gallinae genotype B by sequencing and phylogenetic analyses, providing relevant data for studying the ecology and population genetic structures of trichomonads and for the prevention and control of the diseases they cause.

OBJECTIVETo study the epidemiology and etiologic characteristics of a Dengue fever outbreak in Fuzhou from the beginning of September to the end of October in 2004 in order to understand the source of infection.

METHODSData on descriptive epidemiology was collected to study the characteristics and related factors to the epidemic. Dengue virus was isolated through the use of C6/36 cell line while viral serotypes were identified by indirect immunofluorecent assay with type-specific monoclonal antibody. The sources of infection were traced by nucleotide sequencing.

RESULTSDuring the epidemic, 93 cases occured consistently with the region entomoplily growth and decay. The viruses of 6 strains isolated from 10 patients' blood specimens were identified as dengue virus type 1. Phylogenetic evidence suggested that the viral isolate had high genetic relation with the isolates from Kampuchea (DENV-1/KHM/2001; GenBank Accession No. L0904278).

CONCLUSIONThe epidemic was caused by introduction of patients migrating into Fuzhou.

Objective: To explore the clinical diagnosis and treatment of seminal vesicle cyst (SVC) associated with ipsilateral renal agenesis (Zinner syndrome) in order to promote the understanding of the disease. METHODS: We retrospectively analyzed the clinical data about 1 case ofZinner syndrome diagnosed and treated in our hospital and reviewed the literature related to this disease in domestic and foreign authoritative databases. RESULTS: The patient was a 23-year-old male, diagnosed with Zinner syndrome, treated bytransrectal aspiration of SVC, and discharged from hospital 3 days postoperatively. Follow-upat 6 months after discharge found that the patient no longer felt perineal discomfort in the endstage of urination, but transrectal ultrasonography of the prostate revealedthe samevolume of fluid in the left seminal vesicles as before,which indicated recurrence. CONCLUSIONS SVC associated with ipsilateral renal agenesis can be considered asZinner syndrome. Transrectal aspiration of SVCcan relieve the local symptoms of the patient but relapse may easilyoccur. Therefore it is not recommended as the first-choice treatment of the disease.

UPLC-Q-TOF-MS combined with network pharmacology and experimental verification was used to explore the mechanism of acupoint sticking therapy(AST) in the intervention of bronchial asthma(BA). The chemical components of Sinapis Semen, Cory-dalis Rhizoma, Kansui Radix, Asari Radix et Rhizoma, and Zingiberis Rhizoma Recens were retrieved from TCMSP as self-built database. The active components in AST drugs were analyzed by UPLC-Q-TOF-MS, and the targets were screened out in TCMSP and Swiss-TargetPrediction. Targets of BA were collected from GeneCards, and the intersection of active components and targets was obtained by Venny 2.1.0. The potential targets were imported into STRING and DAVID for PPI, GO, and KEGG analyses. The asthma model induced by house dust mite(HDM) was established in mice. The mechanism of AST on asthmatic mice was explored by pulmonary function, Western blot, and flow cytometry. The results indicated that 54 active components were obtained by UPLC-Q-TOF-MS and 162 potential targets were obtained from the intersection. The first 53 targets were selected as key targets. PPI, GO, and KEGG analyses showed that AST presumedly acted on SRC, PIK3 CA, and other targets through active components such as sinoacutine, sinapic acid, dihydrocapsaicin, and 6-gingerol and regulated PI3 K-AKT, ErbB, chemokine, sphingolipid, and other signaling pathways to intervene in the pathological mechanism of BA. AST can improve lung function, down-regulate the expression of PI3 K and p-AKT proteins in lung tissues, enhance the expression of PETN protein, and reduce the level of type Ⅱ innate immune cells(ILC2 s) in lung tissues of asthmatic mice. In conclusion, AST may inhibit ILC2 s by down-regulating the PI3 K-AKT pathway to relieve asthmatic airway inflammation and reduce airway hyperresponsiveness.
