Objective To research early pathological morphology and clinical significance of perforated duodenal ulcer (PDU) closed after non-surgical treatment. Methods Observed morphological changes of duodenal ulcer (DU) lesion with gastroscopy for 302 patients of PDU with non-surgical treatment in early period,when the perforation closed and measured up the clinical indicators during this hospitalization.Results There were 255 patients to be diagnosed with DU caused the perforation. These lesions were characteristic and shown the PDU closed at the bottom and the deep concave ulcers, except for 1 case which complicated by duodenal fistula. These ulcer types were diverse according to the time difference after treatment. No case of re-perforated ulcers or recurrence of peritonitis caused by gastroscopy. Conclusions Deep concave ulcer with A1 phase mainly is an early pathological manifestations of the DU after treated the PDU with non-surgical method characteristically. The wall of the closure of the serosal side is an original form closed perforated ulcer by non-surgical treatment. The risk of perforation associated with the following factors:( 1 )A single DU is located in the anterior wall region. (2)The shape of two kissing DU. (3)The diameter of DU ≥ 1.1 cm. In this case,early diagnosis by using endoscopy is a safe way.

ObjectiveTo explore the clinical efficacy of Gouteng prescription in treating the patients with primary hypertension with anxiety disorder due to yang hyperactivity and heat toxin and the impact of the formula on the balance of inflammatory cytokines. MethodA total of 98 patients diagnosed with primary hypertension and anxiety disorder were randomized into control and observation groups. On the basis of conventional western medicine treatment for hypertension， the control group （47 patients） was treated with Shugan Jieyu capsules for 8 weeks， while the treatment group （51 patients） with Gouteng prescription for 8 weeks. The two groups were compared in terms of the blood pressure level， 24-hour blood pressure variability， Hamilton anxiety scale （HAMA） score， Pittsburgh sleep quality index （PSQI） score， quality of life （SF-36 scale） score， traditional Chinese medicine （TCM） syndrome score and efficacy， incidence of adverse reactions， and the levels of interleukin （IL）-1β， IL-6， IL-10， and IL-4 in the serum of peripheral blood. ResultThe final trial was completed with 95 patients， including 46 in the control group and 49 in the observation group. The treatment in both groups lowered the blood pressure and blood pressure variability （P<0.05， P<0.01）. The observation group outperformed the control group in recovering the systolic blood pressure （SBP）， 24-hour mean systolic blood pressure （24 h SBP）， 24-hour systolic blood pressure variability （24 h SBPV）， and 24-hour diastolic blood pressure variability （24 h DBPV） （P<0.05）. After treatment， the HAMA and PSQI scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower HAMA and PSQI scores than the control group （P<0.05）. Compared with those before treatment， the SF-36 scores in both groups increased （P<0.05， P<0.01）. After treatment， the observation group had higher scores of physiological function （PF）， bodily pain （BP）， social function （SF）， role-emotional （RE）， and mental health （MH） indicators than the control group （P<0.05）. After treatment， the TCM syndrome scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower score than the control group （P<0.05）. The total response rate regarding TCM syndrome in the observation group was 85.71% （42/49）， which was higher than that （63.04%， 29/46） in the control group （χ²=6.621， P<0.05）. The treatment in both groups lowered the levels of pro-inflammatory cytokines （IL-1β， IL-6） and elevated the levels of anti-inflammatory cytokines （IL-10， IL-4） （P<0.05， P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.05）. There were no adverse events during the research process. ConclusionGouteng prescription can recover the blood pressure level， reduce blood pressure variability， suppress anxiety state， improve sleep and quality of life， decrease TCM syndrome score， increase total response rate， lower serum IL-1β and IL-6 levels， and elevate serum IL-10 and IL-4 levels in the patients with primary hypertension complicated with anxiety disorder due to yang hyperactivity and heat toxin. It may exert the effects by regulating the balance of pro-inflammatory and anti-inflammatory cytokines.
