Objective To observe the clinical features of 575 patients with cardiac diseases from the First Affiliated Hospital of Shantou University Medical College,and to get a preliminary understanding of the incidence of cardia cancer in high incidence area of Chaoshan cardia lesions.Methods Recorded the clinical data of the patients with pathological changes of gastric cardia diagnosed in the First Affiliated Hospital of Shantou University Medical College from 2007 to 2011.Analyzed the distributions of these patients by sex,age and pathological changes.Results There were 575 cases with all kinds of pathological changes of gastric cardia enrolled in this hospital,including 16.34% of chronic inflammation,3.3% of low grade intraepithelial neoplasia,2.26% of high grade intraepithelial neoplasia and 78.09% of gastric cardia cancer.Most patients were gastric cardia cancer.Trend χ2 test results showed that the numbers of gastric cardia cancer patients increased with age(P =0.000).The prevalence of pathological changes of gastric cardia in males was obviously higher than that in females.In gastric cardia cancer the ratio of male to female was 4.76∶1.Conclusion Most of the patients with gastric cardia pathological changes admitted in the First Affiliated Hospital of Shantou University Medical College are middle -aged and elderly men,and gastric cardia cancer is common with a higher frequency in males than that in females.

Objective To investigate the clinicopathological features of gastric cardia cancer with neuroendo-crine cell differentiation(NED).Methods From September 2007 to October 2014,the clinicopathological features of 70 gastric cardia cancer patients with NED and 76 cases without NED confirmed by surgical pathology specimens and immunohistochemistry (Syn and CgA)in the First Affiliated Hospital of Shantou University Medical College were ret-rospectively analyzed and compared.Results The positive expression rates of synaptophysin(Syn)and chromogranin A(CgA)were 43.2% and 22.6%,respectively.Tumor differentiation was significantly related with NED (χ2 =4.989,P =0.026).Tumors with NED were larger and had deeper invasion,but they were not statistically significant. Conclusion Immunohistochemistry is important to the diagnosis of NED.Gastric cardia cancer with NED has poorer differentiation.

OBJECTIVE: To evaluate the efficacy and safety of Mahuang Zhisou Capsule (MHZSC), a compound traditional Chinese herbal medicine, in treatment of acute upper respiratory tract infection of wind-cold syndrome. METHODS: A multi-center, double-blind, double dummy, randomized controlled trial was conducted. A total of 240 patients were randomized into treatment group (120 cases, treated with MHZSC) and control group (120 cases, treated with Mahuang Zhisou Pill). The therapeutic course was 3 days. RESULTS: Seven cases were excluded and three cases lost to follow-up. Two hundred and thirty-three cases entered intention-to-treat (ITT) analysis and 230 cases fitted in per-protocol population set (PPS) analysis. After treatment, the therapeutic effect of upper respiratory tract infection was calculated by ITT and PPS analysis respectively. The significant response rate and total response rate in the treatment group were 78.07% and 98.25% (ITT and PPS), while the significant response rates in the control group were 70.59% (ITT) and 70.69%(PPS), and the total response rates were 95.80% (ITT) and 95.69% (PPS) respectively. There were no significant differences in clinical efficacy between the two groups (P>0.05). CONCLUSION: MHZSC is effective and safe in treatment of acute upper respiratory tract infection of external wind-cold syndrome.

OBJECTIVETo explore the relationship between expression of coiled-coil domain-containing protein 80(CCDC80) and obesity in serum and adipose tissues.

METHODSA cross-sectional survey was conducted in a hospital in Tangshan in September 2010. 100 people including 78 healthy people and 22 with type-2 diabetes were recruited. Another 36 female patients with benign tumor of Obstetrics and Gynecology were also recruited. Demographic characteristics and serum samples were collected from all subjects, basic biochemical indicators were tested. All subjects were divided into 'Normal Weight' and 'Overweight and Obese' according to their BMI (BMI <24.0 kg/m(2); BMI≥24 kg/m(2)). Serum CCDC80 of the 100 subjects was detected by ELISA. Visceral and subcutaneous fat were derived from the other 36 female subjects, and Real-time PCR was used to detect CCDC80 mRNA expression in adipose tissues. Pearson correlation and multiple linear regression were used to analyze the correlation between serum or adipose CCDC80 expression and waist, BMI, and other biochemical indicators.

RESULTSThe age of 100 subjects was (52.9±8.4) years old. 44% of them were women (44 cases) and 56% of them were men (56 cases). After dividing them into three groups according to their BMI, covariance analysis were conducted, and age and gender were adjusted. The HDL-C level was significantly different among three groups (F = 10.73, P < 0.001): 'Overweight and obese combined with diabetes' group ((0.90±0.06) mmol/L)< 'Overweight and obese' group ((1.14±0.04) mmol/L) < 'Normal weight' group ((1.28±0.05) mmol/L). The adjusted expression of serum CCDC80 of the 100 subjects was (5.84±0.16) pg/ml, (5.81±0.98) pg/ml among men and (5.97±0.89) pg/ml among women, and there was no significant difference (t = -0.812, P = 0.419) between genders. ANOVA revealed that there was no significant differences of the expression of serum CCDC80 among three groups (F = 1.06, P = 0.351), 'Normal weight' group was (5.84±0.16) pg/ml, 'overweight and obese' group was (6.11±0.14) pg/ml, and 'Overweight and obese combined with diabetes' group was (5.84±0.19) pg/ml. The analysis showed that FBG had a negative correlation with serum CCDC80 (R(b) = -0.223, P = 0.026). Multivariate linear regression had a similar result, with 1 mmol/L increase of serum FBG, serum CCDC80 decreases for 0.24 pg/ml (β = -0.24, 95% CI: -0.21--0.02). There was also a negative correlation between serum CCDC80 and FBG in overweight and obese people (R(a) = -0.368, P = 0.013). Besides, CCDC80 mRNA was detected in both subcutaneous and visceral adipose tissue of 36 cases, the expression level was 0.06±0.02 for subcutaneous fat, was 0.05±0.04 for visceral fat, and the expression in visceral fat was lower (0.05±0.03) than that in subcutaneous fat (0.06±0.03) (t = 2.50, P = 0.025) among overweight and obese group. There was a negative correlation between waist and visceral CCDC80 mRNA expression (r = -0.472, P = 0.035).

CONCLUSIONThis study suggested that CCDC80 may be involved in energy and insulin metabolism, and plays a protective role in obesity and diabetes.

To evaluate the safety and efficacy of andrographolide drop-pill in treatment of acute upper respiratory tract infection with external wind-heat syndrome.

ObjectiveTo investigate the pharmacological effect and metabolic mechanism of Linderae Radix on the intrauterine adhesion （IUA） rat model. MethodAn IUA rat model was induced by mechanical injury and infection. Molecular biology and pharmacology techniques were employed to evaluate the inhibitory effect of Linderae Radix extract （LAE） on fibrosis in IUA. Serum metabolomics analysis based on gas chromatography-mass spectrometry （GC-MS） was conducted to explore the metabolic regulation mechanism of LAE. ResultAnimal experiments showed that LAE significantly improved the morphology and structural damage of uterine tissue cells in the IUA rat model， promoted endometrial proliferation， vascular regeneration， and morphological recovery， inhibited the mRNA expression of transforming growth factor-β₁ （TGF-β₁）， Smad2， and Smad3， and increased the expression of Smad7 mRNA to suppress fibrosis. Additionally， LAE significantly suppressed the levels of estrogen （E₂）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and tumor necrosis factor-α （TNF-α） expression （P<0.01）， thereby improving the uterine microenvironment. Metabolomics analysis revealed significant metabolic abnormalities in the serum of IUA rats compared with the results in the normal group， and nine differential metabolites were identified. LAE effectively ameliorated these metabolic abnormalities， primarily by influencing six differential metabolites， including five shared metabolites among the nine identified markers： L-aspartic acid， L-pyroglutamic acid， L-serine， glucose， and L-norvaline. Pathway enrichment analysis indicated that the aminoacyl-tRNA biosynthesis pathway was the main affecting mechanism. ConclusionIn combination with the pharmacological research results， LAE effectively improved uterine damage and inhibited fibrosis in the IUA rat model. Its mechanism may involve the inhibition of the aminoacyl-tRNA biosynthesis pathway and the improvement of the microenvironment.

Isolation rearing (IR) enhances aggressive behavior, and the central serotonin (5-hydroxytryptamine, 5-HT) system has been linked to IR-induced aggression. However, whether the alteration of central serotonin is the cause or consequence of enhanced aggression is still unknown. In the present study, using mice deficient in central serotonin Tph2 and Lmx1b, we examined the association between central serotonin and aggression with or without social isolation. We demonstrated that central serotonergic neurons are critical for the enhanced aggression after IR. 5-HT depletion in wild-type mice increased aggression. On the other hand, application of 5-HT in Lmx1b mice inhibited the enhancement of aggression under social isolation conditions. Dopamine was downregulated in Lmx1b mice. Similar to 5-HT, L-DOPA decreased aggression in Lmx1b mice. Our results link the serotoninergic system directly to aggression and this may have clinical implications for aggression-related human conditions.
