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 effect of Xuebijing injection on transfusion and systemic inflammation in traumatic coagulopathy patients. Methods Seventy-nine patients were randomly divided into Xuebijing Group (36 cases) and Control Group (43 cases). Xuebijing group received Xuebijing injection in addition to the regular treatment received by control group. Levels of TNF-α, IL-6, IL-8 and transfusion amount between two groups were compared. Results Coagulation abnormality was almost corrected in all patients after treatment. In Xuebijing Group, transfusion of RBC, FFP and cryoprecipitate were significantly less than that in control group (P<0.05). At 72 h after admission, TNFα, IL-6 and IL-8 were significantly lower in Xuebijing Group (P < 0.05). Conclusion Xuebijing injection could reduce transfusion in traumatic coagulopathy patients , possibly resulting from its antagonism against systemic inflammation.

Objective: To investigate the effect of Guangdong Shenqu (GSQ) on intestinal flora structure in mice with food stagnation through 16S rDNA sequencing. Methods: Mice were randomly assigned to control, model, GSQ low-dose (GSQL), GSQ medium-dose (GSQM), GSQ high-dose (GSQH), and lacidophilin tablets (LAB) groups, with each group containing 10 mice. A food stagnation and internal heat mouse model was established through intragastric administration of a mixture of beeswax and olive oil (1:15). The control group was administered normal saline, and the model group was administered beeswax and olive oil to maintain a state. The GSQL (2 g/kg), GSQM (4 g/kg), GSQH (8 g/kg), and LAB groups (0.625 g/kg) were administered corresponding drugs for 5 d. After administration, 16S rDNA sequencing was performed to assess gut microbiota in mouse fecal samples. Results: The model group exhibited significant intestinal flora changes. Following GSQ administration, the abundance and diversity index of the intestinal flora increased significantly, the number of bacterial species was regulated, and α and β diversity were improved. GSQ administration increased the abundance of probiotics, including Clostridia, Lachnospirales, and Lactobacillus, whereas the abundance of conditional pathogenic bacteria, such as Allobaculum, Erysipelotrichaceae, and Bacteroides decreased. Functional prediction analysis indicated that the pathogenesis of food stagnation and GSQ intervention were primarily associated with carbohydrate, lipid, and amino acid metabolism, among other metabolic pathways. Conclusion The digestive mechanism of GSQ may be attributed to its role in restoring diversity and abundance within the intestinal flora, thereby improving the composition and structure of the intestinal flora in mice and subsequently influencing the regulation of metabolic pathways.

Objective To evaluate the differences among five representative and useful Doppler parameters in the diagnosis of the three common types of renal artery stenosis (RAS). Methods Five Doppler parameters including renal peak systolic velocity (RPSV), renal-aortic ratio (RAR), renal-interlobar ratio (RIR),acceleration time (AT),and resistant index (RI) were measured in 221 patients before renal arteriography. Differences between the groups of patients with various clinical causes of RAS were analyzed by Chi-Squared test. One-way ANOVA or t test were used to compare the means between different groups.The optimal cutoff value was determined with the maximum sum of sensitivity and specificity. Results Of the 442 renal arteries (main and accessory renal arteries) demonstrated at arteriography,214 were normal or stenosed less than 50 %, 204 stenoses 50% - 99 %, and 24 occlusions. RIR, RAR and RI were significantly different between the atherosclerotic and non-atherosclerotic RAS groups (P ＜0.05), while RPSV and AT were not. The optimal cutoff values of RAR,RIR and RI for detecting RAS between the atherosclerotic and non-atherosclerotic groups were much different (2.5 versus 1.9, 5. 1 versus 6.5, 0.57 versus 0.50,respectively) ,but those of RPSV and AT were similar or the same (170 cm/s versus 200 cm/s,51 ms versus 51 ms,respectively). Conclusions In the case of RAS (diameter reduction≥50%),it is advised to establish separate cutoff values of RAR, RIR and RI according to atherosclerotic and non-atherosclerotic RAS, but the same cutoff value of RPSV and AT can be applied. RIR is a good Doppler parameter in the diagnosis of RAS,especially atherosclerotic and fibromuscular dysplasia RAS.

Compared to that with laparoscopic assisted approach, intracorporeal anastomosis with totally laparoscopic radical total gastrectomy has the advantages of smaller incision, and better vision for operation, and may also be fit for patients with large size lesion, high-located lesions, or obesity. It remains controversial though several surgeons have reported the safety and feasibility of intracorporeal anastomosis with totally laparoscopic total gastrectomy. This review describes the recent technical advances in intracorporeal anastomoses with totally laparoscopic total gastrectomy, focusing on the reconstruction skills and indications. Current data on totally laparoscopic total gastric resection for gastric carcinoma revealed that all digestive tract reconstructions were performed with esophagus-jejunum Roux-en-Y anastomosis, and different reconstruction techniques of such Roux-en-Y anastomosis have certain advantages and disadvantages. Surgeons should make choice based on tumor location, esophageal diameter and personal skills in order to achieve maximal benefit to patients.

OBJECTIVETo study the effect of GABA transporter (GAT-1) on the analgesic action of oxysophoridine (OSR) in the central nervous system of mice.

METHODHot plate test was used to observe and analyze the effect of gamma aminobutyric acid and the inhibitor of GAT-1 (NO-711) on the analgesic action of oxysophoridine. Real time RT-PCR was used to investigate the influence of OSR on the expression of GAT-1 mRNA induced by formalin in spinal cord and brain of mice.

RESULTBoth GABA (2.0 mg x kg(-1), icv) and NO-711(0.125 mg x kg(-1), icv) enhanced the analgesic action of OSR (32.0 mg x kg(-1), iv) in the hot plate test, and the latencies was markedly increased (P < 0.05, P < 0.01). OSR (500.0 mg x kg(-1), iv) significantly inhibited the expression of GAT-1 mRNA induced by formalin (P < 0.05).

CONCLUSIONGAT-1 was involved in the analgesia effect of OSR and the down-regulation of GAT-1 mRNA enhanced the analgesic effect.

Objective To develop anxiety scale suitable for Chinese pregnant women and evaluate its reliability and validity. Methods Based on existing research results and clinical experience,this study compiled pregnancy anxiety scale(PAS). A sample of 509 pregnant women were selected for investigation and 65 of them were randomly retested for test-retest reliability with 2 week interval. Item analysis was con-ducted to screen valid items. Then the construct validity of the scale was tested by exploratory factor analysis ( EFA) and confirmatory factor analysis(CFA). Finally the reliability and criterion validity of the scale were evaluated using Cronbach's α coefficient,retest reliability coefficient and Pearson correlation coefficient. Re-sults The PAS was composed of 27 items in four factors,including worry about delivery,worry about them-selves,worry about fetal health and general anxiety. The four factors were extracted by EFA which could ex-plain 62. 48% of the total variance. Besides,the result of CFA demonstrated that the model fitted the data with well construct validity (χ2/df=1. 89,RMR=0. 04,RMSEA=0. 06,IFI=0. 92,TLI=0. 91,CFI=0. 92, PGFI=0. 70,PNFI=0. 74,PCFI=0. 81). The score of the pregnancy-related anxiety scale and its factors scores were positively correlated with the scores of pregnancy-related anxiety questionnaire(PAQ) and child-birth attitudes questionnaire(CAQ). The correlation coefficients were 0. 60-0. 80 and 0. 50-0. 78 respectively (all P<0. 01). The Cronbach's α coefficient was 0. 93 for the total scale and that of the four factors ranged from 0. 82 to 0. 90. The test-retest reliability was 0. 68 for the total scale and ranged from 0. 54 to 0. 75 for the four factors. Conclusion The PAS has a good reliability and validity,and it can be used as a valid tool to measure the anxiety level of pregnant women.

Objective To investigate the relation between intrauterine growth and the development of carotid atherosclerosis in later life. Methods The intima-media thickness of carotid was measured with ultrasonography in 2036 people aged above fifty who had complete birth records, and divided into normal and abnormal group. They were asked to fill in the cardio-cerebrovascular questionnaire, and venous blood samples were taken and analysed for various biochemical parameters. The relation between carotid atherosclerosis and various parameters at birth and in adult life was assessed. Results The birthweight and head circumference in abnormal group were less than those in normal. The prevalence of carotid atherosclerosis was greatest in those weighed 2500g or less, whose risk of carotid atherosclerosis was greater than those weighed between 3000g and 3500g, after adjustment for cardiovascular risk factors. Conclusions Increased atherogenesis may be one independent mechanism mediating the epidemiological link between impaired fetal growth and vascular disease.
