In recent years，with the change in lifestyle and social environment and the increase in pressure in both life and work，male fertility has decreased significantly in China，and the incidence of male infertility has increased year by year，which has brought great challenges to andrologists. Traditional Chinese medicine （TCM） has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility，the China Association of Chinese Medicine （CACM） invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia，abnormal semen liquefaction，varicocele，immune infertility，improving success ratio of assisted reproductive technology，and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages，characteristics，disadvantages，diseases responding specifically，and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility，western medicine cannot achieve a good curative effect，while TCM，taking the holistic view as the core，specializes in improving functional diseases and can correspond to multiple targets and factors，with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists，increase mutual learning and communication between TCM and western physicians，provide patients with excellent and personalized treatment plans in clinical practice，and improve the curative effect of male infertility and fertility of males in China.

Experimental research on male infertility is critical to the study of the pathogenesis of male infertility and the evaluation of drug therapy. This paper reviewed animal experiments on male infertility in recent years. The experimental models of male infertility mainly include oligoasthenozoospermia （OA），teratozoospermia，azoospermia， and varicocele animal models. The OA animal models are mostly induced by glycosides of Tripterygium wilfordii （GTW）， adenine，hydrocortisone， and radiation，which are mainly chemical means. The animal models of azoospermia were usually constructed by intraperitoneal injection of bissulfonyl alkylating agent busulfan and immersion of scrotum in 43 ℃ water. There are few studies on animal models of teratozoospermia，and the induction methods by GTW and methyl methanesulfonate（MMS） are common. The animal models of varicocele-caused infertility are usually induced by operation. The ligation of the middle division of the left renal vein between the lateral inferior vena cava and the medial spermatic vein has a significant influence on testicular morphology and epididymal sperm quality. Animal experimental studies have shown that classic prescriptions for tonifying the kidney and promoting spermatogenesis represented by Wuzi Yanzongwan and clinical empirical prescriptions by modern research have played a significant role in the treatment of male infertility. The mechanism of tonifying the kidney in the treatment of male infertility mainly focuses on inhibiting spermatogenic cell apoptosis. The kidney-tonifying method can regulate the apoptosis of spermatogenic cells，which provides a new treatment idea and a reliable scientific basis for traditional Chinese medicine in the field of male reproduction.

Objective:To explore the risk factors and preventive strategies of pancreatitis after percutaneous transhepatic biliary drainage (PTBD) in patients with pancreatic cancer and obstructive jaundice.Methods:A total of 241 patients were retrospectively analyzed from May 2001 to October 2014 in Tianjin Medical University Cancer Institute and Hospital. The possibly correlated 9 factors were analyzed, including gender, age, hemoglobin level, total bilirubin level, degree of pancreatic duct dilatation, degree of pancreatic atrophy, degree of biliary stenosis, the pancreatic duct visualization, and drainage mode.Results:Univariate analysis suggested that pancreatic duct dilatation, pancreatic atrophy, visualized pancreatic duct and drainage mode were associated with the incidence of pancreatitis after PTBD ( P<0.05). Logistic regression analysis showed that visualization of pancreatic duct ( OR=6.33) was a risk factor for pancreatitis, while pancreatic duct dilatation ( OR=0.14), pancreatic atrophy ( OR=0.12) and external drainage ( OR=0.11) were protective factors for pancreatitis. Conclusion:In pateints with pancreatic cancer and obstructive jaundice, pancreatic duct dilatation and pancreatic atrophy predict low risk of pancreatitis after PTBD,while intraoperative pancreatic duct visualization and internal or external drainage may increase the incidence of postoperative pancreatitis.

Objective:To explore the correlation between different types of microcirculation alterations and the prognosis in patients with septic shock.Methods:This research employed a prospective observational study methodology for selecting subjects with septic shock. Side-stream dark field(SDF) was used to monitor the sublingual microcirculation to determine the total vascular density (TVD), perfused vessel density (PVD), the proportion of perfused vessels (PPV), and the microvascular flow index (MFI), heterogeneity index (HI) indicators. At the bedside, patients with microcirculation disorders were divided into four types: stasis, dilution, heterogeneity, and hyperdynamic. The 30-day survival status after enrollment and hemodynamics parameters were recorded.Results:A total of 64 patients with septic shock were selected in the study, including 18 cases of stasis type, 11 of dilution type, 18 of heterogeneous type, and 17 of hyperdynamic type. There were statistical differences in the mean arterial pressure (MAP) [stasis:(77±9) mmHg (1 mmHg=0.133 kPa), dilution:(80±11) mmHg, heterogeneity: (78±12) mmHg, hyperdynamic:(88±12) mmHg], TVD [ stasis:(10.84±3.01) mm/mm 2, dilution:(9.64±1.72) mm/mm 2, heterogeneity:(11.39±2.18) mm/mm 2, hyperdynamic: (11.87±2.67) mm/mm 2 ], PVD [stasis:(5.93±1.94) mm/mm 2, dilution:(6.86±1.48) mm/mm 2, heterogeneity: (8.31±1.78) mm/mm 2, hyperdynamic:(9.68±2.46) mm/mm 2], PPV [stasis:52.45 (46.25, 63.33)%, dilution:73.70 (61.50, 75.20)%, heterogeneity: 71.25 (67.95, 77.00)%, hyperdynamic:80.70 (77.25, 86.45)%], MFI(stasis:1.34±0.45, dilution: 1.70±0.38, heterogeneity:1.82±0.28, hyperdynamic:2.25±0.33), and HI [stasis:0.68 (0.51, 1.87), dilution: 0.57 (0.49, 0.64), heterogeneity:0.70 (0.59, 0.91), hyperdynamic: 0.40 (0.37, 0.52)] of the four types of microcirculation alterations. The cumulative survival rates in stasis, dilution, heterogeneity and hyperdynamic types at 30 day were 7/18, 4/11, 10/18 and 14/17, respectively, which in stasis and dilution types was significantly lower than that of hyperdynamic type (χ2=7.221, P=0.007;χ 2=6.764, P=0.009). Multivariate Cox regression analysis showed the type of microcirculation alterations (stasis: RR=4.551, 95 %CI 1.228-16.864, P=0.023; dilution: RR=4.086, 95 %CI 1.011-16.503, P=0.048), acute physiology and chronic health evaluation Ⅱ ( RR=1.077, 95 %CI 1.006-1.153, P=0.032) were independent prognostic risk factors. Conclusions:Microcirculation alterations are common in patients with septic shock, and it is hard to predict the types of microcirculation alterations with hemodynamics parameters. The prognosis of patients with septic shock is related to the types of microcirculation alterations, suggesting that routine monitoring of microcirculation might be helpful to guide hemodynamic therapy.

Objective: To investigate the quantitative relationship between liver fat content and bone mineral density (BMD) in middle-aged and elderly people. Methods: Totally 184 middle-aged and elderly community residents were recruited from March to June 2016, including 68 males and 116 females. MRI mDIXON-Quant and quantitative CT (QCT) examinations were performed to determine the content of liver fat and L1-L3 vertebral BMD. The subjects were divided into four groups according to the quartiles of liver fat content, and the baseline characteristics and other variables of different groups were were identified by using one-way analysis of Variance. The relationship between liver fat content and lumbar vertebral BMD was assessed with Spearman correlation and partial correlation analysis. Result: Subjects with higher hepatic fat content had lower spine BMD and higher body mass index (BMI), waist circumference. Liver fat content was negatively correlated with BMD (r=-0.203, P=0.003). After age and body weight were controlled, the negative correlation between liver fat content and BMD was still significant (r=-0.291, P<0.001), in males (r=-0.283, P=0.021) and in females (r=-0.210, P=0.025). Conclusion Liver fat content is negatively correlated with lumbar vertebral BMD in middle-aged and elderly people.

OBJECTIVETo explore the value of single nucleotide polymorphism array (SNP-array) for the analysis of pediatric patients with growth retardation.

METHODSOne hundred eighty one children with growth retardation were enrolled. DNA was extracted from peripheral samples from the patients, and whole genome copy number variations (CNVs) were detected using Illumina Human Cyto SNP-12. All identified CNVs were further analyzed with reference to databases including ClinGen, ClinVar, DECIPHER, OMIM and DGV as well as comprehensive review of literature from PubMed to determine their pathogenicity.

RESULTSForty seven patients (26%) with abnormal CNVs were detected, which included 12 known microdeletions/microduplications syndrome (26%), 10 pathogenic non-syndromic CNVs (21%), 3 numerical chromosome aberrations (6%), 3 unbalanced translocations (6%), 4 pathogenic mosaicisms (9%) and 15 cases with unknown clinical significance (32%). After excluding obvious numerical and/or structural chromosomal abnormalities, this study has detected 15 pathogenic microdeletions/microduplications sized 5 Mb or less, which may be missed by routine chromosomal karyotyping. In addition, there were 3 cases with loss of heterozygoisty (LOH) containing known or predicted imprinting genes as well as 2 cases with suspected parental consanguinity.

CONCLUSIONSNP-array technology is a powerful tool for the genetic diagnosis of children with growth disorders with advantages of high resolution and improved accuracy.
