To explain the relation between diabetic vasculopathy and'Blood blocking collaterals and phlegm turbidness not being removed'proposed by Mr.ZHU Kan-yu.It is believed that the turbidness is the basic pathological product during the development of diabetes.Blood glucose remains high,which reflects the disorders of transportation and distribution of turbid yin and qi in the body.That is to say that the thick coreal nutrients in the vessels are unable to be distributed and absorbed but stay in the vessels as turbid pathologic factors.Blood stasis and phlegm is the further result of turbid pathologic factors.The TCM explanation of diabetic vasculopathy is that phlegm,turbidness,blood stasis block the meridians and collaterals.Those visible pathological factors deposit in vessels and cause narrow vessels and thick walls.Meanwhile the deposit stimulates,spreads,erodes and burns the walls and finally ruins the walls.

ObjectiveTo evaluate the predictive value of the sperm quality to fertilization outcomes after short-time insemination.MethodsA total of 558 cycles of short-time insemination in the Reproductive Medical Center of Henan Provincial People's Hospital during January 2009 to June 2010 excluding patients aged ＞ 38 years and M Ⅱ oocyte number ＜ 3 were analyzed retrospectively.According to whether undergo rescue intracytoplasmic sperm injection( Re-ICSI),all cycles were divided into in vitro fertilization (IVF)group (472 cycles) and rescue intracytoplasmic sperm injection (Re-ICSI) group (86 cycles).Both IVFgroup and Re-ICSI group were subdivided into primary infertility and secondary infertility according to previous history of pregnancy.269 primary infertility cycles and 203 secondary infertility cycles were characterized in IVF group; and 64 primary infertility cycles and 22 secondary infertility cycles were characterized in Re-ICSI group.x2 test was applied for comparison of embryo plant rate,clinical pregnancy rate,early miscarriage rate between IVF and Re-ICSI groups,while Fisher test was used for comparison of live birth rate.and Mann-Whitney U test was utilized for comparison of duration of infertility,forward moving sperm counts,abnormal sperm rate,sperm acrosin activity between IVF and Re-ICSI groups.ResultsThe embryo plant rate,clinical pregnancy rate,early miscarriage rate,live birth rate of IVF group were:29.4％,44.9％,13.4％,37.0％ respectively; the above indicators in Re-ICSI group were:25.7％,34.6％,10.7％,29.6％ respectively,the differences of the indicators between the two groups had no statisticalsigmficance (x2 =0.869,2.963,0.010,P =0.351,0.085,0.922,0.098).Median of duration of infertility,forward moving sperm counts,abnormal sperm rate,sperm acrosin activity of primary infertility cycles in IVF group were:4.00(3.00 -6.00) years,58.37(33.64 - 102.27) × 106,81.09％ (79.41％ -88.69％ ),76.30 (48.50 - 92.46 ) μIU/106 sperm respectively ; in Re-ICSI group were:5.00 ( 3.25 -8.00) years,36.33 (20.59 -64.43 ) × 106,85.5％ (81.28％ - 89.02％ ),47.14( 31.61 -90.24) μIU/106 sperm respectively,the differences of them between the two groups had statistical significance (Z =-2.617, -3.505, -3.553, -3.530,P =0.009,0.000,0.000,0.000).Median of duration of infertility,forward moving sperm counts,abnormal sperm rate,sperm acrosin activity of secondary infertility cycles in IVF group were:5.00 (3.00 -7.00) years,63.00 (34.20 - 107.73 ) × 106,81.29％ (79.90 -86.09) ％,78.34 ( 53.87 - 98.00) μIU/106 sperm respectively,in Re-ICSI group were:5.00 ( 3.75 -7.00) years,28.80 ( 18.57 - 48.56 ) × 106,88.79％ ( 84.04 - 95.64 ) ％,54.70 ( 39.73 - 76.77 ) μIU/106 sperm respectively,the differences of them between the two groups showed statistical significance except duration of infertility (Z =- 0.338,- 3.505,- 3.553,- 3.530,P =0.735,0.000,0.000,0.006).ConclusionThe duration of infertility,forward moving sperm counts,abnormal sperm rate,sperm acrosin activity have predictive value of fertilization outcomes after short-time insemination.

Men with diabetic erectile dysfunction (ED) respond poorly to the currently available oral phosphodiesterase-5 inhibitors. Therefore, functional therapies for diabetic ED are needed. Stromal vascular fraction (SVF) and the adenovirus-mediated cartilage oligomeric matrix angiopoietin-1 (Ad-COMP-Ang1) gene are known to play critical roles in penile erection. We previously reported that SVF and Ad-COMP-Ang1 have only a short-term effect in restoring erectile function. Further improvements to ED therapy are needed for long-lasting effects. In the present study, we aimed to test if the combination of SVF and Ad-COMP-Ang1 could extend the erection effect in diabetic ED. We found that the combination therapy showed a long-term effect in restoring erectile function through enhanced penile endothelial and neural cell regeneration. Combination therapy with SVF and Ad-COMP-Ang1 notably restored cavernous endothelial cell numbers, pericyte numbers, endothelial cell-cell junctions, decreased cavernous endothelial cell permeability, and promoted neural regeneration for at least 4 weeks in diabetic mice. In summary, this is an initial description of the long-term effect of combination therapy with SVF and Ad-COMP-Ang1 in restoring erectile function through a dual effect on endothelial and neural cell regeneration. Such combination therapy may have therapeutic potential for the treatment of diabetic ED.

There have been many studies on the nutrition and the growth status of children from rural and remote western regions of China,whereas researches on children from urban low-income families are scarce.This study aimed to investigate the growth and nutritional status of children under five years of age from urban low-income families in China.There were 169 children aged 25-60 months recruited from Xiangtan and Jilin,two cities with a population of 2.81 million and 4.26 million respectively,in China in this cluster cross-sectional study.Data were collected on demographic and socioeconomic characteristics,the feeding practices and the incidence of anemia and diarrhea.The results showed that the prevalence of low birth weight and macrosomia was 7.l％ and 9.5％ for the two cities,respectively,which was higher than that for other cities in China (1.5％ and 5.9％).Of all the sampled children,14.6％ and 8.2％ suffered anemia and diarrhea,respectively.Multivariate analysis showed that legumes or nuts fed in a 24-h recall increased the risk of anemia (OR=4.9).Children whose caregivers began to introduce complementary foods relatively late would have high diarrhea prevalence (OR=1.4).In conclusion,the prevalence of anemia and diarrhea in under-five children from urban low-income families in China is relatively high.The growth and nutritional status of these children is greatly affected by feeding practices.A series of measures should be taken by relevant government departments to improve the health of these children.

Objective To investigate the titer stability of the harvest solution of severe acute respiratory syndrome coronavirus2(SARS-CoV-2)at 2 ～ 8 ℃ and the inactivation effect of β-propiolactone inactivator on the virus.Methods Three batches of SARS-CoV-2 harvest solution(batch numbers:202111001,202111002 and 202111003)were stored at 2 ～ 8 ℃ for 12 d and sampled every 3 d(0,3,6,9 and 12 d)for detection of the titers by Karber method;Three batches of virus harvest solution equilibrated overnight at 2 ～ 8 ℃ were inactivated by adding β-propiolactone at a volume fraction of 1∶4 000 and detected for the titers at different inactivation time points(0,0.5,1,1.5,2,3,4,8,16 and 24 h),of which samples inactivated for 8,16 and 24 h were taken for inactivation verification,and samples inactivated for 24 h were observed by transmission electron microscope.Results The titers of SARS-CoV-2 decreased with the prolongation of storage time at 2 ～8 ℃,which showed no obvious decrease during 0 ～ 3 d,while decreased from the initial 7.75,6 and 7.5 lgCCID_(50)/mL to5.75,4.625 and 6.25 lgCCID_(50)/mL on day 12,indicating that the virus activity showed a gradual decrease trend at 2 ～8 ℃；With the inactivation time,the virus titer decreased continuously and could not be detected after inactivation for 3 h.Transmission electron microscope observation showed that the inactivated virus particles were intact and the spike protein was evenly distributed.Conclusion The virulence of SARS-CoV-2 stored at 2 ～ 8 ℃ was unstable,so the subsequent inactivation and purification process should be carried out as soon as possible;The titer of virus could not be detected after3 h of inactivation,which provided a reference for the determination of the inactivation process.

An efficient modified route based on the targeting mechanism of antibacterial fluoroquinolones for the shift from the antibacterial activity to the antitumor one was further developed. Using a fused heterocyclic ring, s-triazolothiadiazine as a carboxyl bioisostere of ciprofloxacin, the title compounds, 1-cyclopropyl-6-fluoro-7-piperazin-1-yl-3-(6-substituted-phenyl-7H-[1, 2, 4]triazolo[3, 4-b][1, 3, 4]thiadiazin-3-yl)-quinolin-4(1H)-ones (5a-5e) and their corresponding N-acetyl products (6a-6e), were designed and synthesized, separately. Meaningfully, a ring-contraction of fused six-membered thiadiazine occurred by a sulfur extrusion reaction gave new tri-acetylated fused heterocycles related to pyrazolo[5, 1-c][1, 2, 4] triazoles (7a-7e). The in vitro antitumor activity against L1210, CHO and HL60 cell lines was also evaluated for the synthesized fifteen heterocycles compared to parent ciprofloxacin by methylthiazole trazolium (MTT) assay. Interestingly, the results displayed that fifteen fused heterocyclic compounds showed more significant growth inhibitory activity (IC50 < 25.0 micromo x L(-1)) than that of parent ciprofloxacin (IC50 > 150.0 micromol x L(-1)), and the active order decreased from 7a-7e to 5a-5e to 6a-6e, respective.

Objective To evaluate the value of volume measured by multi-slice spiral CT in preoperative N staging of gastric canc-er.Methods CT data of 1 93 cases of gastric cancer proven pathologically were collected and analyzed.Volume of the tumor was cal-culated in the portal phase,and the correlation between the results and N staging was evaluated.ROC curve was used to get diagnos-tic value to differentiate N stages.Results Intra-observer Kappa value was 0.77 (P < 0.05 ),0.72 (P < 0.05 ),Inter-observer Kappa value was 0.69 (P <0.05).The tumor volume data was positively correlated with different N stages (r=0.568,P <0.05). ROC curve showed that the volume could help differentiate between stage N0 and stage N1 - N3 (cutoff 12.06 cm3 ,sensitivity 55%,specificity 95%),stage N0-N1 and stage N2-N3 (cutoff 22.35 cm3 ,sensitivity 66%,specificity 86%),stage N0-N2 and stage N3 (cutoff 25.95 cm3 ,sensitivity 62%,specificity 89%)respectively.Conclusion The volume of gastric cancer measured by CT plays an important part in predicting lymph node metastasis staging and optimizing individualized clinical strategy for patients.

Objective To evaluate the effectiveness of peer support interventions on exclusive breastfeeding among primiparous women. Methods Randomized controlled trials (RCTs) that reportedthe effectiveness of peer support interventions on exclusive breastfeeding among primiparous women were retrieved in several electronic databases. Data were analyzed using RevMan 5.3 software after quality assessment and data extraction. Results A total of 9 RCTs which included 1435 patients were incorporated in this meta-analysis. The meta-analysis revealed that peer support interventions could increase the rate of exclusive breastfeeding(OR=2.84, 95％CI2.22-3.64, P<0.01), increase duration of exclusive breastfeeding(WMD=43.66, 95％CI28.04-59.27, P<0.01). Subgroup analysis showed that peer support increased the rate of exclusive breastfeeding atone month(OR=1.84,95％CI1.24-2.73, P<0.01), three months(OR=2.28, 95％CI1.67-3.12, P<0.01)and six months(OR=3.42,95％CI2.46-4.76, P<0.01) of postpartum. Conclusions Peer support interventions could increase exclusive breastfeeding rate and duration of exclusive breastfeeding. It is worth being popularized.

Objective: To explore the influence of body mass index (BMI) on postoperative complications and survival in patients with esophageal squamous cell carcinoma (ESCC) using propensity score matched (PSM) methods. Methods: We retrospectively analyzed clinical data of 533 patients with ESCC who were admitted for thoracic surgery in Shandong Provincial Hospital, between January 2011 and December 2012. After conducting PSM methods to balance the covariates, the incidence of postoperative complications and sur-vival rate were compared between the two groups. The effects of BMI on postoperative complications and survival were analyzed with multivariate Logistic regression and Cox proportional hazard analyses, respectively. Survival analysis was performed using Kaplan-Mei-er curves and Log-rank test. Results: After adjusting the PSM and confounding variables, the two groups were well matched (146 pa-tients each) without significant differences in baseline characteristics. The incidence of wound infection and respiratory system compli-cations in the H-BMI group (BMI≥25 kg/m2) were significantly higher than those in the N-BMI group (18.5-25 kg/m2) (P<0.05). H-BMI was an independent risk factor for wound infection and respiratory system complications. In the present study, no significant differ-ence was observed in the 3-year overall survival between H-BMI and N-BMI patients (54.1% vs. 47.8%, P=0.212). Patients with H-BMI had significantly better 5-year overall survival than those with N-BMI (39% vs. 25%, P=0.016). The subgroup analysis showed that pa-tients with H-BMI had a better overall survival than those with N-BMI in stages Ⅰ-Ⅱ (47.3% vs. 29.0%, P=0.032). However, this difference was not significant when patients were stratified into stages Ⅲ and Ⅳ (24.5% vs. 16.7%, P=0.393). Conclusions: H-BMI appears not to decrease the overall survival of patients with ESCC. Therefore, ESCC in patients with H-BMI can receive surgical treatment safely, but proper intraoperative management and close postoperative monitoring should be performed.
