Objective To investigate the association between the EPHX2 polymorphism G860A and the risk of hypertension in mild ages. Methods In a hospital based case-control study, one common polymorphism C860A in EPHX2 gene in a case-control study of 100 hypertension and 300 age- and sex frequency - matched disease-free controls were genotyped in a Southern Chinese population. SAS 9. 13 was used toanalysis the polymorphism and hypertension risk. Results Genotype frequencies of EPHX2 G860Alocus between the cases and the controls were significantly different (P =0. 01). Compared with the most common 860GG genotype, the 860GA heterozygote had an increased risk of hypertension (adjusted OR =1.98; 95%CI = 1.19 -3.51), the AA homozygote had a further increased risk of hypertension (adjusted OR =2. 84; 95%CI = 1.01 -6. 11). There was a significant trend for an allele dose effect on risk of hypertension (P trend = 0. 03). Conclusions EPHX2 polymorphism G860A is associated with an increased risk of hypertension, and the 860A variant may be a marker for susceptibility to hypertension.

BACKGROUND: A simple use of antibiotic drugs as anti-infection therapy after joint replacement is not enough for subsequent debridement and secondary revision surgeries. Therefore, our team intended to confirm the feasible use of controlled-release microspheres in the local anti-infection treatment.OBJECTIVE: To prepare the Human beta defense 3 (HBD-3)/poly(lactic-co-glycolic acid) (PLGA) micro-spheres and to investigate the microsphere physicochemical properties and drug release profile in vitro.METHODS: With PLGA as a carrier,HBD-3/PLGA controlled-release microspheres were prepared by using double emulsion-solvent evaporation method. Scanning electron microscopy was used to observe its surface morphology.The size of each microsphere was accurately determined using scaleplate. Drug loading capacity and encapsulation efficiency of HBD-3/PLGA controlled-release microspheres were calculated using spectrophotometer. HBD-3/PLGA microsphere controlled-release time was determined in order to analyze the drug release profile of the microsphere. RESULTS AND CONCLUSION: The HBD-3/PLGA controlled-release microsphere possessed smooth surface, uniform distribution and good liquidity.The average particle size was 219.49 nm, the drug loading capacity of HBD-3 was (20.67±0.17)% and the encapsulation efficiency was (54.52±1.31)%. The cumulative release percentage of HBD-3 was(74.12±0.43)%. The HBD-3/PLGA controlled-release microsphere has well controlled-release performance in vitro. In theory, the purpose of antibacterial controlled-release can be achieved,laying a foundation for subsequent animal antibacterial experiments.

Objective To compare the surgical outcomes between laparoscopic and open surgeries in treatment of ectopic oviduct pregnancy, and investigate the clinical value of laparoscopic surgery. Methods Two hundred and forty-six patients with ectopic oviduct pregnancy in our hospital from June 2009 to March 2013 were retrospectively analyzed. 134 cases were treated with laparoscopic operation and 112 with open surgery. Some parameters such as operative time, blood loss, usage of pain-killer, hospital stay were compared between both groups. Results All operations were successful. Laparoscopic surgery was shown to be superior to open operation in the parameters of operative time, blood loss, usage of pain-killer and hospital stay ( < 0.05) . Conclusion Compared with open operation, laparoscopic surgery has the advantages of less trauma and rapid postoperative rehabilitation. It may become the first line treatment for ectopic oviduct pregnancy.

In this study the ability of the monoclonal anti-idiotypic antibody NP30 was tested as a substitute of diagnostic antigen in detecting antibody of Schistosoma japonicum from human sera by use of ELISA. The results showed that the seropositive rate was 98% with NP30 in the group of acute infection, which was comparable to 94% with gut associated antigens (GAA)and 98% with the soluble egg antigens (SEA); 87% with NP30 in the group of chronic infection which was comparable to 86% with GAA but lower than that of 98% with SEA. The false positive rate was about 3% for all three diagnostic antigens. The results also showed that the geometric mean titer (GMT) of antibody to NP30 was higher than that to GAA but lower than that to SEA in the acute infection group and the GMT of antibody to NP30 was lower than both those to GAA and to SEA in the chronic infection group,suggesting that the antibody to NP30 appeared earlier and decayed more quickly during the process of infection. The authors suggested that NP30 could be used for the diagnosis of schistosomiasis japonica.

Objective:To observe the effect of local excision under ultrasonography with immediate mammoplasty in granulomatous lobular mastitis.Methods:Fifty-three patients with granulomatous lobular mastitis admitted from Jan 2017 to Jul 2020 were retrospectively analyzed. Combined with sonographic findings and clinical manifestations, patients were divided into four types: type Ⅰ, single mass; Type Ⅱ, single mass located in one quadrant with one or no skin lesion; Type Ⅲ, multi-quadrant involved with one or no skin lesion; Type Ⅳ, multiple abscesses with multiple lesions in the skin. Twenty-five patients underwent wide local excision (control group); Twenty-eight patients underwent local excision under ultrasonography with immediate mammoplasty (experiment group). Patients with erythema nodosum or in type Ⅳ were given antibiotics and corticosteroid therapy preoperatively for 1 week and postoperatively for 5 days. The others went straight to surgery.Results:All patients were followed up for 1 year. In the experiment group, 28 patients had primary wound healing, and 3 patients had poor wound healing after operation (all were of type Ⅳ). The control group had 6 cases of recurrence(were of type Ⅲ and type Ⅳ). There was significant difference of the recurrence rate between the two groups (0 vs. 24%, χ 2=6.033, P=0.014), and the aesthetic effect of local excision under ultrasonography with immediate mammoplasty was better than that of wide local excision(93% vs. 68%, χ 2=5.330, P=0.020). Conclusion:The recurrence rate of local excision under ultrasonography with immediate mammoplasty is low, and with a satisfactory cosmetic effect.

OBJECTIVE:
To observe the short-term results of Tos modified combined approach tympanoplasty (MCAT) in chronic suppurative otitis media.
METHOD:
This study is an observational study. The data of 26 patients (28 ears) underwent MCAT were collected. The surgical techniques, complications and preoperative and postoperative air-bone gap (ABG) were analyzed.
RESULT:
Of 28 ears, 26 ears (92.86%) get dry after surgery. 3 ears (10.71%)repaired tympanic membranes and reperforate postoperatively in which 2 minimal perforations were cured to close up patient treatment. One ear develops posterosuperior retraction pocket and one ear re-occurs cholesteatoma. One ear occurs blunting in the anterior sulcus and one ear has lateralization of the tympanic membrane. There are no hearing worsen and facial nerve palsy. For hearing, the postoperative pure tone threshold is better than preoperation (42.8 +/- 17.97 vs 47.49 +/- 18.01, P < 0.05) and postoperative ABG shrinks significantly (19.76 +/- 7. 49 vs 30.65 +/- 10.02, P < 0.01).
CONCLUSION
Based on the short-term results, Tos' MCAT can successfully dissect the diseases of tympanic cavity and mastoid and develop a stable aerating middle ear with a complete hearing conduction. It is safe and feasible in the treatment of chronic suppurative otitis media, as well as in the poor-pneumatic mastoid.

OBJECTIVE: To explore the immunological mechanism of exfoliative tongue fur in children with asthma. METHODS: Thirty-nine children with asthma, twenty-eight children with repetitive respiratory tract infection (non-asthma) and eleven healthy children were divided into five groups, which were asthma with exfoliative fur or with non-exfoliative fur groups, non-asthma with exfoliative fur or with non-exfoliative fur groups and normal control group. The concentrations of keratin 13 and bcl-2 in cells exfoliated from tongue fur were detected by immunohistochemical method. The expression levels of blood cell chemokine receptor-3 (CCR-3) and CD4(+) were examined by flow cytometry, and the levels of serum cortisol and IgE were detected by radioimmunoassay. RESULTS: The levels of blood CD4(+) and CCR-3 of children with asthma and exfoliative fur were higher than those in the asthma with non-exfoliative fur group and the normal control group (P<0.05). The serum level of cortisol in the groups of asthma with exfoliative fur and non-asthma with exfoliative fur were lower than that in the other groups (P<0.05). The serum levels of IgE in asthma with exfoliative fur or with non-exfoliative fur groups were higher than that in the other groups (P<0.05). Concentrations of keratin 13 in the cells exfoliated from tongue fur in the groups of asthma or non-asthma with exfoliative fur were lower than that of the other groups (P<0.05). There was no significant difference of expression level of bcl-2 in the cells exfoliated from tongue fur among these five groups. CONCLUSION: There is a reasonably close relationship between the formation of exfoliative tongue fur and the immune system such as low level of serum cortisol and high levels of blood CD4(+) and CCR-3, which may all promote the formation of exfoliative fur. The disability of keratinization and apoptosis of epithelial cells of tongue may also be one cause for its formation.
