The TCM theory of XueyuYundu believes that blood stasis and poison is the fundament of endometriosis. Long term of blood stasis may convert to poison and further aggravate the blood stasis. This article has summarized literatures about poison stasis syndrome and blood stasis syndrome. On this basis, we introduced a self-made prescription, QuyuJiedu Decoction, and the theoretical and laboratory study progress of this decoction, for the purpose of providing a new method for treating endometriosis.

OBJECTIVE: To discuss the effect of different doses intranasal corticosteroids on remodeling of allergic rhinitis (AR) mice nasal mucosa and expression level of matrix metalloproteinase-9 (MMP-9). METHOD: Thirty BALB/c female mice were divided into five groups randomly and received OVA or normal saline (NS) with intraperitoneal injection or nasal challenge, respectively. The treatment groups received additional different doses of budesonide (0.6 μg/20 g, 3.0 μg/20 g and 15.0 μg/20 g) daily for 16 weeks. We assessed the nasal symptoms at 4 and 16 weeks. Collected the mice nasal tissue, and then stained with hematoxylin-eosin, Masson's Trichrome, and periodic acid-schiff respectively to evaluate airway remodeling at 16 weeks. MMP-9 was measured with enzyme-linked immunosorbent assay (ELISA). Result: Times of rubbing, sneezes and infiltrate of eosinophil increased more in B group than in A group, and subepithelial fibrosis, collagen deposition, goblet cell hyperplasia, and submucosal gland hypertrophy were only observed in B group at 16 weeks. The nasal symptoms and eosinophil infiltration were inhibited by treatment with budesonide from a dose of 0.6 μg onwards, while the prevention of structure changes was only observed with 3.0 μg onwards. In addition, intranasal budesonide reduced MMP-9 in the nasal of AR mice. CONCLUSION The study suggests that higher dose intranasal corticosteroids might inhibit the airway remodeling of nasal mucosa by reducing MMP-9.

Objective To observe the changes of abdominal oxygen saturation in very low birth weight infants (VLBWI)with feeding intolerance (FI)within 1 4 days after birth monitored by near infrared spectroscopy (NIRS).Methods VLBWI fitting entry criteria were enrolled into this study.NIRS monitoring was carried out to detect cerebral oxygen saturation (ScO2 )and abdominal oxygen saturation (SsO2 ).Data were analyzed between FI infants and feeding tolerance (FT)infants.FI was defined as follows:gastric residual of more than 50% of the previous feeding volume;emesis or abdominal distention or both;decrease,delay or discontinuation of enteral feedings. Results 93 VLBWI were enrolled.52 cases(55.91 %)presented with FI,including 29 cases(31 .1 9%)of gastric residual increasing and 23 cases(24.73%)of emesis with or without abdominal distention within 1 4 days after birth. The levels of SsO2 and SsO2 /ScO2 showed no differences in infants with FT and with FI within 24h after birth (P >0.05).The change rates of the median of SsO2 and SsO2 /ScO2 in FT infants were similar during 1 4 days (P >0.05).While both the change rates of SsO2 and SsO2 /ScO2 were markedly decreased 1 day before and the day of FI (P <0.01 ).The decreasing degree of SsO2 was similar between infants with gastric residual increasing and infants with emesis with or without abdominal distention[(1 6.2 ±5.1 )vs (1 7.4 ±3.6)%,t =0.733,P =0.476]. Conclusion Abdominal oxygen saturation measured by NIRS may be a useful method for infants adjusting the feeding plan.

Objective To investigate effects of different ventilation methods during pulmonary surfactant(PS) administration on cerebral oxygen metabolism in preterm infants with neonatal respiratory distress syndrome.Methods Newborns met the inclusion criteria were enrolled into this study,and they were randomly divided into manual group and mechanical group.During PS administration,the proximal end of the tracheal tube was connected to a bag valve mask device in the manual group or a mechanical ventilator in the mechanical group.Brain near infrared spectroscopy monitoring was carried out to detect the cerebral oxygen saturation(ScO2),and the mean arterial blood pressure (MABP) was simultaneously recorded.Results For all 49 preterm infants,PS was administered to preterm infants with severe respiratory distress syndrome treated with mechanical ventilation,including 24 cases of manual ventilation and 25 cases of mechanical ventilation.The left cerebral ScO2 and correlation coefficient of ScO2 and MABP(rScO2-MABP) showed no difference in both groups before PS administration.During administration,ScO2 dramatically increased in both groups [manual group:(85.88 ± 5.54) ％ vs.(77.31 ± 5.40) ％,t =5.521,P =0.000;mechanical group:(83.88 ± 3.18) ％ vs.(76.53 ±4.38)％,t =6.741,P =0.000],and gradually decreased after administration,the level of ScO2 didn't return to the baseline till the 2nd 5 minutes after PS administration [manual group:(79.25 ± 3.02) ％ vs.(77.31 ± 5.40) ％,t =1.560,P =0.220;mechanical group:(78.59 ± 3.45) ％ vs.(76.53 ± 4.38) ％,t =1.832,P =0.074].The same trend of ScO2 change rate was shown simultaneously in both groups.The rScO2-MABP markedly increased during administration in both groups (manual group:2.34 ±0.16 vs.1.86 ±0.21,t =9.022,P =0.000;mechanical group:2.12 ± 0.15 vs.1.87 ±0.21,t =4.810,P =0.000).The rScO2-MABt,in mechanical group rapidly decreased to baseline during the 1st5 minutes (1.84 ± 0.18 vs.1.87 ± 0.21,t =0.538,P =0.635) but went back to baseline in manual group during the 2nd 5 minutes(1.84 ±0.19 vs.1.86-0.21,t =0.350,P =0.809).Change rates of rScO2-MABP were markedly higher in manual group than those in mechanical group during the 1 st 5 minutes (1.15 ± 0.13 vs.1.00 ± 0.15,t =4.943,P =0.000).Conclusions ScO2 could be affected transiently by PS administration with different methods of ventilation.The effect on cerebral autoregulation in mechanical group is shorter than that in manual group.

Objective To investigate the prevalence status and risk factors of mild cognitive impairment (MCI) in old people in pension facilities in Chongqing, China. Methods From October to November, 2015, the people above 60 years old in four pension facilities in Chongqing were cluster sampled. They were interviewed with Mini-Mental State Examination, Instrumental Activity of Daily Living Scale, self-made general situation questionnaire for the elderly and the Geriatric Depression Scale. Results There were 25 MCI patients identified in 84 old people selected, with the prevalence of 29.76%. MCI prevalence was different with the factors such as genders, educational levels, economical status, smoking, eating freshwater fish frequently, participating in outdoor activities frequently, playing Mahjong/chess/cards fre-quently, watching TV/listening to broadcast/reading newspaper frequently, participating in social activities frequently, having religious be-liefs, suffering high blood pressure (χ2>4.271, P<0.05). Based on multivariate Logistic regression analysis, male was the protective factor (OR=0.055, 95%CI:0.005~0.618), while high blood pressure was the risk factor (OR=8.281, 95%CI:1.278~53.646) to the MCI. Conclu-sion MCI is prevalent in old people in pension facilities in Chongqing, which needs intervention targeted to the risk foctors.

Objective To explore the relationship of different body mass index, waist circumference and serum lipid levels with essential hypertension among residents of Ningbo. And to explore the predictive value of BMI and WC (Waist Cir-cumference) for hypertension. Methods Adopting cluster sampling, 2 303 people (1 081 cases of hypertension and 1 222 people with normal blood pressure) were collected in the four townships of Ningbo City. We conducted questionnaires, physi-cal examination and blood lipid testing for all of subjects. WC group:WC≥85 cm in male or WC≥80 cm in female is central obesity, and the others are normal. BMI groups:BMI≥24 kg/m2 is overweight, and BMI<24 kg/m2 is normal. The relationship of BMI, WC and serum lipid levels with hypertension was analyzed by multivariate unconditional logistic regression model. The predictive value of BMI and WC for hypertension was analyzed by receiver operating characteristic (ROC) curve. Results WC, BMI, total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) in hypertension group were higher than those in control group (P<0.01). And WC, BMI, TG, LDL-C is the impact factor for hypertension. The overweight rate and central obesity rate in hypertension group were higher than control group (P<0.01). TG and LDL-C level abnormality, overweight and central obesity were the risk factors of hypertension. As a risk factor of hypertension, over-weight with central obesity group is higher than overweight with normal waistline group, simple central obesity group and nor-mal group. In the area under the ROC curve, BMI is higher than WC in both male and female population. Conclusion WC, BMI, TG and LDL-C abnormalities were risk factors for hypertension, and BMI was a better predictive factor for hyper-tension than WC.

Objective To investigate the prevalence and risk factors of mild cognitive impairment (MCI) among the old people in Chongqing, China. Methods From October to November, 2015, 1850 persons more than 60-year-old in Chongqing were cluster sampled. They were investigated with self-made general situation questionnaire, Mini-Mental State Examination (MMSE), Instrumental Activity of Daily Living Scale (IADL) and Geriatric Depression Scale (GDS) through face-to-face interview. Enumeration data were tested withχ2 test and multiple Logistic regression. Results MCI prevalence was 11.73%in the old people in Chongqing, and various with the residential re-gions, ages, marital status, literacy, career, smoking, drinking, seafood-eating, egg-eating, exercising, intensive labor, low intensity of labor, housework, outdoor activities, Mahjong/chess/cards playing, TV-watching/radio-listening/newspaper-reading, social activities, obesity, hy-pertension, diabetes, stroke, hyperglycemia, cerebrovascular insufficiency and depression (χ2>4.092, P<0.05). According to multiple Logis-tic regression, living in rural areas, aging, celibacy, obesity, hypertension and depression were the risk factors of MCI;while middle school and above years of schooling, mental workers, smoking cessation, frequent seafood-eating and egg-eating, exercising, daily intensive labor and low intensity of labor, daily and sometimes housework, daily and weekly outdoor activities at least once, daily Mahjong/chess/cards playing and daily TV-watching/radio-listening/newspaper-reading were the preventing factors. Conclusion The morbidity of MCI is high in the old people in Chongqing. It is necessary to take effective intervention in view of the related factors of MCI as early as possible, to delay or prevent the development of MCI to dementia.

Objective To evaluate the efficiency of rotational atherectomy (RA) with drug-eluting stents (DES) by intravascular ultrasound (IVUS) for elderly patients with heavily calcified lesions. Methods Thirteen patients aged above 70 years with heavily calcified coronary artery having underwent the treatment of RA and DES by IVUS were enrolled. The levels of troponin T, creatine kinase isozyme-MB and creatinine were detected before and after operation.The levels of minimus lumen diameter, diameter stenosis rate, effective area of the lumen before and after operation were compared. The immediate success rate was evaluated and the follow-up results were recorded. Results Thirteen patients in accordance with angiography and IVUS examination were confirmed as severe calcification. The levels of troponin T, creatine kinase isozyme-MB and creatinine detected before and after operation had no significantly differences (P>0.05). The levels of minimus lumen diameter, diameter stenosis rate and effective area of the lumen before and after operation had significant differences:(2.06 ± 0.38) mm vs. (3.98 ± 0.76) mm, (73.26 ± 7.02)%vs. (17.00 ± 3.34)%, (4.53 ± 1.50) mm2 vs. (12.54 ± 6.19) mm2, P<0.01. The rate of left anterior descending artery, circumflex artery and right coronary artery calcification was 10/13, 0 and 1/13. All patients′operation was successful. Followed up for (14.6 ± 3.4) months, no patients had angina and myocardial infarction, or required target vessel revascularization. Conclusions RA with DES by IVUS can be safely used in elderly patients with severely calcified coronary artery disease, and can improve the success rate of intervention operation.

Objective:To study the crosstalk between the activating transcription factor 6 (ATF6) and inositol-requiring enzyme 1 (IRE1) - X-box binding protein 1 (XBP1) pathway in oxygen-glucose deprivation/reoxygenation (OGD/R)-injured mouse hippocampal neuronal cell line HT22.Methods:The OGD/R-injured HT22 cell model was used to observe the changes of the indicators of endoplasmic reticulum stress (ERS), cell viability, and apoptosis at different OGD/R time points (0, 3, 6, 12, and 24 hours). HT22 cells in the logarithmic growth phase were randomized into blank control group, control+ATF6 activator (AA147) group, control+IRE1 inhibitor (4μ8c) group, OGD/R model group, OGD/R+AA147 group and OGD/R+4μ8c group (10 μmol/L AA147 or 16 μmol/L 4μ8c was given during the whole process in the AA147 group and 4μ8c group). Western blotting was used to detect the expression of ERS-related proteins [glucose-regulated protein 78 (GRP78), phosphorylated-inositol-requiring enzyme 1 (p-IRE1), and phosphorylated-eukaryotic translation initiation factor-2α (p-eIF2α)], and apoptosis-related proteins (Bcl-2, Bax, caspase-3, and cleaved caspase-3). The mRNA of ERS-related genes, and ATF6 [homocysteine-inducible, endoplasmic reticulum stress-inducible, ubiquitin-like domain member 1 (Herpud1), protein disulfide isomerase associated 4 (Pdia4) and Sel-1 suppressor of lin-12-like (Sel1L)] and spliced XBP1 [XBP1s, include DnaJ heat shock protein family member B9 (Erdj4), Sec24 related gene family, member D (Sec24d) and signal sequence receptor, gamma (Ssr3)] induced transcriptional response-related genes were measured by real-time quantitative polymerase chain reaction (RT-qPCR). A cell counting kit-8 (CCK-8) assay was used to detect the viability of HT22 cells. Immunofluorescence was utilized to test the expression of cleaved caspase-3.Results:Compared with the blank control group, the expression of ERS-related proteins p-IRE1 and p-eIF2α were significantly increased at 12 hours and 3 hours following OGD/R, respectively (p-IRE1/β-actin: 2.09±0.10 vs. 1.00±0.00, p-eIF2α/β-actin: 1.39±0.11 vs. 1.00±0.00, both P < 0.01). The mRNA expressions of ERS-related genes [ATF6, XBP1s, unspliced XBP1 (XBP1u), activating transcription factor 4 (ATF4), CCAAT/EBP homologous protein (CHOP)] were also upregulated in different OGD/R timepoint in HT22 cells, which indicated ERS was activated in OGD/R-stimulated HT22 cells. Compared with the OGD/R model group, the expression of protein p-IRE1 was not changed, but the mRNA of XBP1s and XBP1u were obviously downregulated in the OGD/R+AA147 group [XBP1s (2 -ΔΔCt): 0.76 (0.71, 0.92) vs. 1.13 (1.03, 1.29), XBP1u (2 -ΔΔCt): 0.29±0.05 vs. 0.52±0.04, both P < 0.01], whereas the expressions of XBP1s-induced transcriptional response downstream genes did not change significantly. Compared with the OGD/R model group, the protein of short-form ATF6 (sATF6) and GRP78 were not changed after administration of 4μ8c, neither was the mRNA expression of ATF6-induced transcriptional response-related genes. These results showed that the mRNA expression of XBP1s and XBP1u were inhibited by AA147-induced activation of ATF6, but no crosstalk was observed between the transcriptional response induced by ATF6 and XBP1s. Compared with the blank control group, the cell viability decreased significantly at OGD/R 3 hours [(44.64±5.12) % vs. (99.13±5.76) %, P < 0.01], the ratios of apoptosis-related proteins Bax/Bcl-2 and cleaved caspase-3/caspase-3 were significantly increased at OGD/R 3 hours and OGD 0 hour, respectively (Bax/Bcl-2: 6.15±1.65 vs. 1.00±0.00, cleaved caspase-3/caspase-3: 17.48±2.75 vs. 1.00±0.00, both P < 0.01), which indicated that apoptosis was activated in OGD/R-treated HT22 cells. Compared with the OGD/R model group, the cell viability decreased significantly [(36.52±17.78)% vs. (69.90±9.43)%, P < 0.01], and the ratios of Bax/Bcl-2 and cleaved caspase-3/caspase-3 were significantly upregulated in the OGD/R+AA147 group in HT22 cells (Bax/Bcl-2: 2.06±0.31 vs. 1.10±0.25, cleaved caspase-3/caspase-3: 3.35±0.59 vs. 0.55±0.09, both P < 0.01). Conclusion:Under our experimental conditions, no obvious crosstalk between the transcriptional response induced by ATF6 and XBP1s was observed, while ATF6 activation induced by AA147 suppressed mRNA expression of XBP1s and XBP1u and promoted cell death in OGD/R-treated HT22 cells.
