OBJECTIVETo observe mainfestations of syndrome and biochemical indices of hypertensive model rats with excessive accumulation of phlegm-dampness syndrome (EAPDS), and to explore its possible pathological mechanism.

METHODSEAPDS rat model was prepared in 50 Wistar rats by feeding with high fat forage. Meanwhile, a normal control group consisting of 10 Wistar rats was set up by feeding with normal forage. After 25-week continuous feeding, 22 rats with body weight (BW) and blood pressure (BP) exceeding 25% those of the control group were selected as a model group. BW, BP, blood lipids, and related serological indicators were detected in all rats. Morphological changes of target organs were observed. mRNA expression levels of leptin receptor (LepR), Janus kinase2 (Jak2), signal transducer and activator of transcription 3 (Stat3), suppressor of cytokine signaling-3 (Socs3), angiotensin II receptor type 1 (AT1), angiotensin II receptor type 2 (AT2), phosphatidylinositol 3 kinase (P13K), serine threonine kinase (Akt), nuclear factor of kappa B (NF-κBp65), inhibitor of nuclear factor kappa-B kinase α (IKKα), NF-kappa-B inhibitor β (lKKβ), NF-kappa-B inhibitor α (IKBα), and AMP-activated protein kinase (AMPK) were detected by quantitative real-time PCR (qPCR). Expression levels of AT1 and LepR in aorta were detected by immunohistochemical assay and Western blot respectively.

RESULTSCompared with the control group, BW, BP, and blood lipids increased; serum levels of leptin (Lep) , Ang II, Hcy, ET-1, TNF-α, IL-6, and p2-MG increased, but NO decreased in the model group (P < 0.05, P < 0.01). Aortal endothelial injury and smooth muscle cell proliferation occurred in the model group, accompanied with heart and renal injury. Compared with the control group, mRNA expression levels of LepR, Jak2, Stat3, Socs3, AT1 , PI3K, Akt, NF-κB p65, IKKβ, IKBα, and AMPK in aorta were up-regulated significantly (P < 0.05), while the expression of IKKa decreased (P < 0.05). Immunohistochem- ical staining showed, brownish yellow deposit of AT1 and LepR was obviously increased, with more extensively positive distribution. Western blot results showed, as compared with the control group, protein expression levels of AT1 and LepR obviously increased in the model group (P < 0.05).

CONCLUSIONSModel rats exhibited typical syndromes of EAPDS. They put up weight with fat abdomen, gloomy hair, poor appetite, hypersomnia, lowered activities , reduced food intake, loose stool, dark red tongue, white tongue with white, thick, greasy fur. Lep could be taken as one of objective indicators for evaluating hypertension rat model with EAPDS.

Objective To assess the absorbance rate of the fat after the operation of breast augmentation of the repeated injection of low volume, using ultrasonic imaging method. Methods Thirty three patients were injected with low volume of autologous fat (50-60 ml per time) to bilateral breasts for 1-5 times and breast sonographic examination was performed to evaluate the grafted fat tissues. The thickness of the retromammary fat layer before and after each injection was measured to calculate the absorbance index. Results The 264 points of breast were measured in this study. The fat was distributed in the retro-mammary fat layers at 224 points of the breast and in the pectoralis major muscle layer at 32 points of the breast, and the others distributed in the mammary gland layer.The average thickness of the retromammary fat layer increased gradually from 0.2 cm before the first operation to 1. 0 cm after the fifth operation. The average absorbance index one month after each operation was 34 %-66 %. Conclusion The present study demonstrates that breast augmentation by repeated autologous fat graft with low volume injection at each time is applicable and satisfactory and that breast ultrasound is an accurate and simple method to e-valuate the absorbance index.

Objective To evaluate the effects of fluid resuscitation and large-volume hemofiltration (HVHF) on the Alveolar-arterial oxygen exchange in patients with refractory septic shock. Method A total of 89 intensive care patients with refractory septic shock treated with fluid resuscitation and/or HVHF were enrolled between August 2006 and December 2009. All the patients were randomly divided into two groups. In group A, patients were treated with fluid resuscitation, n = 41 cases) and in group B, patients were treated with large-volume hemofiltration and fluid resuscitation, n =48). The O2 content of central venous blood(CcvO2), arterial oxygen content (CaO2), Alveolar-arterial oxygen pressure difference (P(A-a)DO2), the ratio of arterial oxygen pressure/alveolar oxygen pressure (PaO2/PAO2), respiratory index (RI) and oxygenation index (OI) were checked. The levels of oxygen exchange in two groups were detected by arterial blood gas analysis before treatnent, 24 hour, 72 hour and 7 days after treatment. The APACHE Ⅱ scores in patients with refractory septic shock were measured before and the 7th day after treatment with HVHF and/or fluid resuscitation respectively. Data were analyzed by using t -test and chi-square test to compare the differences and ratio between two groups and were expressed in mean ± standard deviation, and the analysis of variance was done with SPSS version 12.0 software. Results ① The differences in CcvO2 and CaO2 between two groups were[(0.60±0.24) vs. (0.72±-0.28), P ＜0.05 and (0.84±0.43) vs. (0.94±0.46), P ＜0.05]; and the oxygen extraction rates (O2ER) were significantly different between two groups [(28.7±2.4) vs. (21.7±3.4), P<0.01];② The levels of P(A-a)DO2、ratio of PaO2/PAO2、RI and OI in group B were reduced more significantly than in group A (P<0.05 or P<0.01);③The APACHE Ⅱ scores in both groups were gradually reduced after treatment for 7 days, and the APACHE Ⅱscore in group B on the 7th day of treatment were lower than that in group A[(17.2 ± 6.8) vs. (8.2 ± 3.8), P ＜ 0.01]. Conclusions Fluid resuscitation and HVHF could improve alveolar-arterial-oxygen exchange in patients with refractory septic shock, and at the same time decreased the APACHE Ⅱ scores, improving the survival rate of patients.

Objective To evaluate the ultrasonographic (US) features and evolution of breast fat necrosis after cosmetic augmentation with autologous fat obtained by liposuction, to help distinguish fat necrosis from more ominous breast masses. Methods Breast sonography was performed on 38 patients underwent bilateral breast augmentation by autologous fat injection to evaluate the grafted fat tissues in interval of 3-6 month after the operation. Observations in follow up sonography included the sizes,positions, shape,echogenicity,margin features, calcifications and evolutions of the suspicious nodules in the breasts. Results Seventy-six nodules occurred in 25 of the 38 patients were detected after the fat graft. Among the 76 nodules,52 were cystic(68. 4%) ,8 were complex(10. 5%) and 16 were solid(21.1%). The analysis of the predominant features of the nodules sonographic appearances were as follows: all the nodules had no flow signal, 66 (86. 8%) had clear margins,54(71. 1%) had regular shapes,52 were cystic(68. 4%) ,63(82. 9% ) had no calcifications, 10(13. 2%) had egg-like calcifications,74(97. 4% ) had no halo,and the positions of the solid components in 8 complex nodules move following the change of the detected body position. There were 7 nodules with fat necrosis removed surgically and confirmed by pathology. Conclusions Breast ultrasound is an accurate and simple method to follow up the temporal changes of the fat nodules after autologous fat injection. It may help to avoid unnecessary biopsies.

Abstract Gram-negative ( G-) bacteria, such as denitrifying bacteria and anaerobic ammonia oxidation bacteria, are highly social organisms capable of sophisticated cooperative behavior mediated via quorum sensing. As signal molecules of the chemical communication, N-acyl-homoserine lactones ( AHLs ) can mediate the quorum sensing of the functional microbial population and regulate the population density. To understand the growth of functional microbial population and the mechanism for biological nitrogen removal in upflow microaerobic sludge reactors ( UMSRs ) treating organic wastewater with low ratio of chemical oxygen demand to total nitrogen, a method was established to simultaneously detect AHLs in the microaerobic processes. Water-sludge mixtures sampled from the UMSRs were pretreated in sequence by liquid-liquid extraction using ethyl acetate, rotary evaporation, constant volume with methanol, separation by C18 column. Gradient elution was carried out using 5 mmol/L ammonium acetate ( containing 0 . 1% formic acid ) and methanol as mobile phases. On the base of multiple reaction monitoring analysis, a triple quadrupole mass spectrometer with an electrospray ionization was introduced to detect the target compounds. Nine kinds of AHLs were used to evaluate the established method and the results showed that the detection limits were 0 . 01-0 . 5 μg/L and all of the AHLs presented excellent linearity with the concentration ranging from 0 . 5 to 100 μg/L. The recovery and relative standard deviation ranged from 62. 5% to 118. 1% and 2. 9% to 12. 1%, respectively. The analysis could be finished within 6. 5 min. The rapid, accurate and precise method for detecting AHLs provided a new insight into the growth and metabolic activity of functional microbial population in the activated sludge processes to understand the mechanism of biological nitrogen removal, suggesting a good application in regulation and operation of wastewater biological treatment processes.

Objective To build predictive model of secondary mild cognitive impairment (MCI) in patients with painful diabetic neuropathy (PDN), and analyze its apply. Methods The patients with PDN were consecutively selected from March 2013 to March 2016. The relevant clinical data were recorded, and the patients were followed up for 1 year. According to the results of follow-up, secondary MCI risk indicators were predicted, and the time window of adverse outcomes event was validated. Results A total of 82 PDN patients completed the study, and secondary MCI occurred in 16 cases. Sixty-six cases had not secondary MCI. The Cox regression model multivariate analysis results showed that the independent influencing factors of secondary MCI was course of PDN, brief pain inventory (BPI) score and neuron-specific enolase (NSE) in patients with PDN (HR = 1.238, 1.336 and 1.450; P<0.05). The secondary time window of the MCI in PDN patients with the course of PDN ≥3.367 years, BPI score≥4.704 scores and NSE ≥ 7.420 μg/L was shorter, in whom BPI score and NSE had a higher evaluation ability. Conclusions The courses of PDN, BPI score and NSE are independent influencing factors of secondary MCI in PDN patients, and the BPI score≥4.704 scores and NSE≥7.420μg/L have a higher evaluation ability.

Objective To evaluate roles of color doppler echocardiography(CDE)and angiocardiography(ANGI)in diagnosis of children's combined with congenital heart diseases(CHD).Methods From Jan.2006 to Jun.2008,31 children with combined with CHD underwent not only CDE but also ANGI.Of those,18 cases were subjected to surgical operation.Main diagnosis and concomitant cardiovascular malformations derived from CDE and ANGI,operative findings as well,were compared.Results In 18 cases undergoing surgery,diagnosis of 15(83.33%)cases from CDE and 17(94.44%)cases from ANGI were in line with the operative findings.Of intracardiac malformations,diffe-rences between CDE and ANGI were:CDE diagnosed 1 case with pulmonary atresia /ventricular septal defect(PA/VSD)as persistent truncus arteriosus(PTA),2 cases with tetralogy of Fallot(TOF)as PA/VSD by mistake,and 1 case with partial anomalous pulmonary venous connection(PAPVC)was suspected by CDE but missed by ANGI,all above mentioned confirmed by sugery;except main diagnosis,CDE missed atrial septal defect(ASD),anomalous origin of right coronary artery and single left coronary for 1 case,respectively.In diagnosing extracardiac abnormal structures:1 case of interrupted aortic arch(IAA)was suspected by CDE but diagnosed and classified by ANGI;for double aortic arch(DAA),pulmonary arteriovenous fistula(PAVF),patent ductus arteriosus(PDA)and absence of right pulmonary artery,1 case of each was missed by CDE;furthermore PDA reported by CDE but not found by ANGI in 4 cases with PA/VSD.Conclusions The diagnostic difference between CDE and ANGI mainly lies in extracardiac malformations including coronary arteries.In diagnosing combined CHD,combination of CDE and ANGI can improve accurate rate.J Appl Clin Pediatr,2009,24(1):44-45

Objective To summarize the sonographic features and differential diagnosis points of mass-type cornual pregnancy. Methods The sonographic ifndings of 23 pathological proven mass-type cornual pregnancy cases enrolled in PUMCH from 2011 January to 2013 January were retrospectively analyzed. Results All pathological proven mass-type cornual pregnancy were located at one corner of the uterus presenting as a heterogenous outward mass. Well-deifned margins were found in 20 cases, and interstitial-line signs were found in 15 cases. The surrounding muscle thickness is 0.1-0.3 cm. Typical hyperechoic villi were found on sonography in cases with bloodβ-hCG>20 000 IU/L. On Doppler, the lesion showed abundant peripheral vascularity with low resistance in 22 cases, 9 lesions also showed abundant internal vascularity. Among 23 mass-type cornual pregnancy cases, 7 cases were misdiagnosed as gestational trophoblastic neoplasia (GTN) due to the similar sonographic characteristics including mixed-echo and abundant vascularity with low resistance. Sixteen cases were diagnosed by ultrasound preoperatively, with featured sonographic signs including mass located in the endometrial extension line;clear margin;peripheral vascularity;or detection of interstitial-line sign and typical villus. Conclusions Mass-type cornual pregnancy may be correctly diagnosed according to the location, boundary of the mass and the distribution of blood flow combining with clinical manifestation and bloodβ-hCG level. Transvaginal sonography could play an important role in diagnosis of cornual pregnancy.

Objective To study the therapeutic effects of omeprazoie in high-dose given by continuous intravenous infusion in the treatment of stress-related mucosal injury of G-I tract in intensive care patients.Method Totally 98 intensive care patients with stress-related mucosal injury(SRMI)were enrolled from August 2006 to October 2008 Department in Intensive Care Unit(ICU)of the Provincial Hospital Affiliated to Shandong University.All the patients were randomly divided into high-dose omeprazoie group(group A)and control group(group B).In group A,omeprazoie was administrated in loading dose of 80 mg Ⅰ.Ⅴ.in 5 minutes followed by maintenance dose of 8.0 mg/h intravenous infusion for 72 hours,while in group B,omeprazoie was given in dose of 40mg/8h intravenous infusion for 72 hours.The pH value of gastric juice was determined by German Roche pH test paper every 2 to 8 hours in the patients of both groups.The coffee like or red juice in the gastrointestine decompressor was observed.At the same time,hemoglobin(HB)was detected by Automatic blood cell analyzer Sysmex XE-2100,blood urea nitrogen(BUN)was determined by Automatic Analyzer Au5400,and buffer excess(BE)was checked by GEM Premie arterial blood gas analyzer in all patients.Data were expressed as mean ± standard deviation(x-± s)and the analysis of variance was done with SPSS 12.0 software.Comparison of mean value between two groups was conducted with t-test and the ratio was calculated by using chi-square test(X2 test).The change was considered as statistically significant if P value was less than 0.05.Results Four,eight,and 24 hours after treatment with omeprazole,the pH values in patients of group A were higher than those in patients of group B(four hous:6.63 ±0.62 vs.3.14 ±0.26,P＜0.01;eight hours and 24 hours:P＜0.05 or P＜0.01).At 8 hours and 24 hours after treatment,the HB was higher,BUN and BE were lower in group A than those in group B(P＜0.03 or P＜0.01).The total rate of hemostasis of upper G-I tract bleeding in group A was higher than that in group B(95.35%vs.78.19%,P＜0.05).Conclusions For treating the intensive care patients with SRMI,the continues intravenous infusion of omeprazole inhigh dose is superior to conventional dosage.
