OBJECTIVETo observe the therapeutic angiogenesis effect of naotai recipe (NR) on local ischemia/reperfusion (I/R) injury of rats by observing signaling pathway of hypoxia-inducible factor-lα (HIF-1α) and vascular endothelial growth factor (VEGF).
METHODSTotally 120 Sprague-Dawley (SD) rats were randomly divided into 4 groups, namely, the normal control group (n =12), the sham-operation group (n =12), the I/R model group (n =48), and the NR group (n =48). Cerebral I/R injury models were established using thread suture method. Rats in the I/R model group and the NR group were sub-divided into 4 sub-groups according to the 1st, 3rd, 5th, and 7th I/R day (n =12). The phenomenon of neovasculization was observed by immunofluorescence staining. The protein and mRNA expression levels of HIF-la, VEGF-A, and VEGFR II receptor were detected by RT-PCR.
RESULTSThere were a large amount of labels for neovasculization in the ischemic area of the NR group. Double-immunofluorescence labeling [vWF (red) and BrdU (green)] was observed in the NR group. Compared with the model group, the HIF-1α protein expression was obviously enhanced on the 1 st day of I/R (P <0.01), and the VEGF protein expression started to enhance on the 3rd day in the NR group (P <0.01). The VEGFR protein expression level was the highest in the NR group on the 5th day of I/R (P <0.01). The protein expression of VEGF and HIF-1α started to decrease on the 7th day of I/R.
CONCLUSIONNR could strengthen angiogenesis after I/R by elevating the expression of HIF-lα and activating HIF-lα/VEGF signaling pathway.

Objective:To explore the effect of cognitive-behavioral therapy on psychological stress and quality of life in patients with pulmonary tuberculosis.Methods:According to two-level cluster random design 461 patients with tuberculosis from 20 communities in Pizhou county of Jiangsu province were selected in the study from September 2018 to November 2018. The intervention group received cognitive-behavioral therapy for two months, while control group received routine follow-up. Anxiety, depression and quality of life were assessed by GAD-7, PHQ-9 and SF-36 scales, respectively. At the same time, the comparison between the two groups was conducted by independent sample t test, and the difference between the two groups before and after treatment was analyzed by paired sample ttest. Results:A total of 454 participants were finally included in this analysis; there were 230 cases in the intervention group and 224 cases in the control group. In the intervention group the scores of anxiety and depression after intervention were significantly lower than the baseline scores [(7.57±5.27) vs. (5.93±2.56), t=-4.245, P<0.01; (8.13±6.01) vs. (6.02±2.67); t=-4.866, P<0.01], and the quality of life score was significantly higher than the baseline score [(58.46±12.71) vs. (74.31±13.22); t=13.108, P<0.01]; while in the control group there were no significant differences in the scores of anxiety, depression and quality of life after intervention, compared with those at baseline [(7.62±5.41) vs.(7.65±5.38); (8.00±5.84) vs. (8.07±5.91); (59.11±13.25) vs. (60.51±13.76); t=0.059, t=0.126, t=1.104, all P>0.05]. However, only for patients with mild and moderate anxiety and depression symptoms in the intervention group, the anxiety and depression scores were decreased after intervention [(7.29±1.21) vs. (5.54±1.71), (11.99±1.31) vs. (9.17±1.55); (7.01±1.47) vs. (4.42±1.22), (11.88±1.12) vs. (8.39±2.33); t=8.056, t=10.020, t=13.558, t=8.852,all P<0.01]. Conclusion:Cognitive-behavioral therapy can relieve the psychological pressure and improve the quality of life in pulmonary tuberculosis patients with mild or moderate anxiety/depression symptoms.

OBJECTIVETo investigate the possible association between the glutamate-cysteine ligase catalytic subunit gene (GCLC) C-129T and modifier subunit gene (GCLM) G-23T polymorphisms with coronary heart disease (CHD) in Chinese population.
METHODSGCLC C-129T and GCLM G-23T genotypes were determined in 212 CHD patients and 218 healthy individuals using a PCR-based restriction fragment length polymorphism (RFLP) method. Odds ratio (OR) for CHD and 95% confidence interval (CI) from unconditional logistic regression models were used to evaluate relative risks.
RESULTSThe T allele of the GCLC C-129T polymorphism was more frequently found in CHD cases than in controls (P < 0.01) and individuals with GCLC-129T allele had a significantly higher risk for CHD (OR = 2.38, 95% CI: 1.25 - 4.54) as compared to individuals with the -129C allele. When compared with CC homozygote, CT heterozygote had a 2.14-fold higher risk for CHD (95% CI: 1.08 - 4.24, P < 0.05) and carriers of the-129T allele (CT or TT genotype) also had a similarly 2.28-fold higher risk for CHD (95% CI: 1.16 - 4.49, P < 0.05). In contrast, the frequency of T allele of the GCLM G-23T polymorphism was lower in CHD patients than that of controls (0.174 vs. 0.264) and individuals with the GCLM-23T allele had a significantly lower risk for CHD (OR = 0.59, 95% CI: 0.42 - 0.82, P < 0.01) as compared to the -23G allele. When compared with GG homozygote, the OR of CHD for GT heterozygote was 0.71 (95% CI: 0.47 - 1.08, P > 0.05), for TT homozygote was 0.18 (95% CI: 0.06 - 0.55, P < 0.01), and for carriers of the -23T allele (GT or TT genotype) was 0.61 (95% CI: 0.42 - 0.92, P < 0.05).
CONCLUSIONThe GCLC C-129T polymorphism may be one of the genetic risk factor while the GCLM G-23T polymorphism may be one of the genetic protective factors for CHD in this Chinese population.

BACKGROUNDThe purpose of this study was to investigate the feasibility of avoiding axillary lymph node dissection (ALND) for patients with only one sentinel lymph node (SLN) metastasis. The characteristics and predictive factors for non-sentinel lymph node (NSLN) metastasis of patients with single positive SLN were also analyzed.
METHODSPatients with no and only one SLN metastasis (0/n and 1/n group, n ≥ 2) were selected from 1228 cases of invasive breast carcinoma, who underwent axillary dissection in Shandong Cancer Hospital between November 1999 and December 2011, to compare the characteristics of NSLN metastasis between them. For the 1/n group, the factors that influenced the NSLN metastasis were analyzed by univariate and multivariate analysis.
RESULTSDifferences of the NSLN metastasis between the 0/n and the 1/n groups were significant (P < 0.001). There was no significant difference between the axillary lymph node metastasis on level III in 1/n group and 0/n group (P = 0.570). When the total SLN number was ≥ 4 and with one positive case, the NSLN metastasis was not significantly different from that in the 0/n group (P = 0.118). In the 1/n group, clinical tumor size (P = 0.012), over-expression of Her-2 (P = 0.003), tumor grade (P = 0.018) and the total number of SLN (P = 0.047) significantly correlated with non-SLN metastasis. Clinical tumor size (P = 0.015) and the expression of Her-2 (P = 0.01) were independent predictive factors for non-SLN metastasis by the Logistic regression model.
CONCLUSIONUnder certain conditions, breast cancer patients with single SLN metastasis could avoid ALND.

OBJECTIVETo evaluate the characteristics of myocardial (18)F-FDG imaging in pilots with regular aerobic exercise training.
METHODSTwenty seven healthy male pilots with regular aerobic exercise training were included in this study. The subjects were divided into fasting (n = 17) or non-fasting group (n = 10). Fluorine-18-labeled deoxyglucose and Tc-99m-sestamibi dual-nuclide myocardial imaging were obtained at rest and at target heart rate during bicycle ergometer test. The exercise and rest myocardial perfusion imaging were analyzed for myocardial ischemia presence. The myocardial metabolism imaging was analyzed with the visual semi-quantitative analyses model of seventeen segments.
RESULTSThe secondary-extreme heart rate (195-age) was achieved in all subjects. There was no myocardial ischemia in all perfusion imaging. In the visual qualitative analyses, four myocardial metabolism imaging failed in the fasting group while one failed in the non-fasting group (P > 0.05). In the visual semi-quantitative analyses, myocardial metabolism imaging scores at rest or exercise in all segments were similar between two groups (P > 0.05). In the fasting group, the myocardial metabolism imaging scores during exercise were significantly higher than those at rest in 6 segments (P < 0.05). In the non-fasting group, the scores of 3 exercise myocardial metabolism imaging were significantly higher than those at rest (P < 0.05).
CONCLUSIONSatisfactory high-quality myocardial metabolism imaging could be obtained at fasting and exercise situations in subjects with regular aerobic exercise.

Prior to fertilization sperm has to undergo an activation process known as capaciation, leading to the acrosome reaction. Till now, little is known about the mechanism for preventing premature capacitation in sperm although decapacitation factors from various sources have been thought to be involved. In this study, we report that NYD-SP27, an isoform of phospholipase C Zeta 1 (PLCZ1), is localized to the sperm acrosome in mouse and human spermatozoa by immunofluorescence using a specific antibody. Western blot and double staining analyses show NYD-SP27 becomes detached from sperm, as they undergo capacitation and acrosome reaction. The absence of HCO3-, a key factor in activating capacitation, from the capacitation-inducing medium prevents the loss of NYD-SP27 from sperm. The anti-NYD-SP27 antibody also prevents the loss of NYD-SP27 from sperm, reduced the number of capacitated sperm, inhibited the acrosome reaction induced by ATP and progesterone, and inhibited agonist-induced PLC-coupled Ca2+ mobilization in sperm, which can be mimicked by the PLC inhibitor, U73122. These data strongly suggest that NYD-SP27 is a physiological inhibitor of PLC that acts as an intrinsic decapacitation factor in sperm to prevent premature capacitation and acrosome reaction.

OBJECTIVETo investigate the food water sources of adults in the four cities of China in summer.
METHODSA total of 64 adults aged 18 - 60 yrs from four cities (Beijing, Shanghai, Chengdu and Guangzhou)were selected using convenient sampling method. The food samples were collected by using duplicate portion method and the water content of food samples were determined by using the national standard. The information on amounts and types of daily drinking soup was recorded by subjects using a quantitative measurement.
RESULTSA total of 63 subjects had completed the investigation. The median of daily water from food of subjects was 1157 ml, while water from staple food was 480 ml, the median ratio of which accounting for 41.8% of water from food. Water from dishes was 427 ml, the median ratio of which accounting for 37.9% of water from food. Water from soups was 133 ml, the median ratio of which accounting for 13.8% of water from food. Water from snacks was 0 ml, the median ratio of which accounting for 6.4% of water from food. The medians of water from staple food (384, 388 and 435 ml, respectively) in Beijing, Shanghai and Guangzhou was significant lower than that of Chengdu subjects' (900 ml, χ(2) = 21.27, P = 0.000). But the median proportion of water from staple food of subjects in Beijing (47.7%) was significantly higher than that in Chengdu (43.2%), Shanghai (42.9%) and Guangzhou (33.9%) (χ(2) = 8.69, P = 0.034). The median of amount and proportion of water from soups of subjects in Guangzhou (267 ml, 24.4%) and Chengdu(278 ml, 15.7%) was significantly higher than that in Shanghai (133 ml, 9.0%) and Beijing (100 ml, 5.8%) (amount: χ(2) = 22.52, P = 0.000;proportion: χ(2) = 16.27, P = 0.001).
CONCLUSIONThe staple food and dishes are the main sources of daily food water.

OBJECTIVEThe purpose of this study was to investigate the clinicopathologic factors associated with false-negative rate of sentinel lymph node biopsy (SLNB) in breast cancer, and to explore how to reduce the false-negative rate of SLNB.
METHODSThe clinicopathological data of 2265 patients with invasive breast carcinoma who underwent sentinel lymph nodes biopsy (SLNB) in Shandong Cancer Hospital between November 1999 and December 2011 were retrospectively analyzed. We screened 1228 patients who received axillary lymph node dissection after SLNB, and studied the clinicopathological factors that could be associated with false-negative rate of SLNB.
RESULTSThe false negative rate of this group was 10.7% (73/683), accuracy rate was 94.1% (1155/1228), and negative predictive value was 88.2% (545/618). Clinical tumor size (all P < 0.05), calendar year of surgery (all P < 0.05) and numbers of detected SLNs (all P < 0.05) were significantly related with false negative rate and accuracy rate of SLNB, determined by single factor analysis. Logistic regression model analysis showed that calendar year of surgery (P = 0.034) and numbers of detected SLNs (P = 0.012) were independent predictive factors for the false negative rate of SLNB.
CONCLUSIONSFalse negative rate and accuracy rate of SLNB are significantly related to the calendar year of surgery and number of detected SLNs. Strict case selection, standard operation procedure, increaseing numbers of detected SLNs, and improvement of the skill of operators are effective measures to reduce the false negative rate of SLNB.

ObjectiveTo evaluate the influence of the resected prostate tissue volume (RPV) on the improvement of International Prostate Symptom Score (IPSS), quality of life (QOL), and voiding function after transurethral resection of the prostate (TURP).
METHODSThis study included 82 men with benign prostatic hyperplasia treated by TURP. Before and three months after TURP, we obtained the IPSS, QOL score, post-voiding residual urine volume (PVR), and maximum urinary flow rate (Qmax) from the patients. We measured the total prostate volume (TPV) and transition zone volume (TZV) by transrectal ultrasound preoperatively and investigate the influence of the RPV, RPV/TZV ratio, and RPV/TPV ratio on the efficiency of TURP.
RESULTSAt three months after TURP, the mean Qmax increased by 9.27 ml/s, IPSS decreased by 15.86, QOL score increased by 3.47, PVR decreased by 87.1 ml, and 72.0% of the patients felt satisfied with the surgical results. There was no statistically significant difference in RPV between the patients satisfied and those dissatisfied with the results. Both the RPV/TPV and RPV/TZV ratios significantly increased in the satisfaction group as compared with the dissatisfaction group (P=0.002 and P=0.004). The areas under the ROC curve for the RPV/TPV and RPV/TZV ratios were 0.793 (P=0.001) and 0.687 (P=0.009), respectively.
CONCLUSIONSRPV is closely related to the short-term outcomes of TURP, and the ratios of RPV/TPV and RPV/TZV may be used as new markers to predict the outcomes of TURP.
