Objective To analyze the relationship between follow-up service, personal characteristics, lifestyle and blood sugar management of diabetic patients in Gansu Province, and put forward scientific suggestions on influencing blood sugar management of diabetic patients. Methods Based on the data of the 6th National Health Service Questionnaire, 273 subjects were included. Chi-square test and unconditional logistic regression were used to analyze the blood glucose control and its influencing factors of diabetic patients. Results A total of 39.56% patients' blood sugar status was well controlled. 76.92% patients signed up for family doctor service, and 77.66% patients took hypoglycemic drugs according to the law of doctor's advice. There were significant differences in blood sugar control among patients in different regions, educational levels and occupational types (P <0.05) , logistic regression analysis showed that Hui patients (OR=0.21), doctors without family contract (OR=2.86) and patients taking hypoglycemic drugs intermittently (OR = 6.58). Conclusion The blood sugar control rate of diabetic patients in Gansu is low, and the nationality, contracted family doctors and medication plan affect the blood sugar control level of patients. In order to ensure the high efficiency of follow-up treatment, the related follow-up services provided by primary medical institutions, it is necessary to provide self-management programs that meet the individual characteristics and meet the needs of the disease.

Acute-on-chronic liver failure (ACLF) is a life-threatening disease with a high risk of multiple organ failure, sepsis, and death. ACLF activates innate and acquired immune responses in human body and thus leads to the progression of persistent systemic inflammatory response syndrome and multiple organ dysfunction, leading to the high mortality rate of this disease. Dysregulated immune response plays a key role in disease progression, and immunotherapy may help to target immune-mediated organ damage and inhibit the progression of liver failure. This article reviews the role and mechanism of drugs and means with a potential immune regulatory effect in ACLF, in order to provide a reference for immunotherapy for ACLF.

Objective:The study investigated and analyzed the health-related quality of life of diabetes patients in Gansu province before and after the healthcare reform and its influencing factors, so as to provide scientific evidence to improve the health-related quality of life of diabetes patients.Methods:The study used data of the fourth and sixth national health service household survey in Gansu province before (2008) and after (2018) medical reform separately, and EQ-5D health utility index was calculated on the basis of Chinese time frade-off values for EuroQol Five-Dimensions Questionnaire Utility Value scoring system.Results:Compared with the period before the healthcare reform, the five dimensions of EQ-5D for residents, aged 15 and above in Gansu, changed significantly after the healthcare reform: action capability improved by 8.08% (27.43% vs. 19.35%), self-care improved by 16.16% (26.55% vs. 10.39%), normal activity improved by 8.97% (28.32% vs. 19.35%), pain/discomfort worsened by 1.38% (38.05% vs. 39.43%), anxiety/depression worsened by 1.83% (16.81% vs. 18.64%), and the EQ-VAS score increased by 3.36 (60.53 vs. 63.89). The health utility index increased by 0.04 (0.83 vs. 0.87). Multivariate regression analysis results showed that the dimension influence factors were not completely consistent, on the whole, the health-related quality of life of diabetes patients with older age, lower education level, no physical exercise and multi chronic diseases was worse ( P<0.05), and multiple chronic disease had the most serious effect on the health of patients with diabetes. The health-related quality of life of diabetes patients with the medical insurance in urban area and after the new medical reform was higher ( P<0.05). Conclusion:The new healthcare reform has active influence on the health-related quality of life of diabetes patients in Gansu province, health care providers and policy makers should pay attention to the impacts of multi prechronic diseases on the health-related quality of life of diabetes patients and the mental health of patients with diabetes.

At present, hepatic encephalopathy has a relatively high mortality and thus greatly affects patients’ quality of life. This article describes the changes of intestinal flora in patients with hepatic encephalopathy and analyzes the mechanism of action of intestinal flora in hepatic encephalopathy and related treatment methods. It is pointed out that the development of hepatic encephalopathy is closely associated with intestinal flora, and clinical treatment by regulating intestinal flora has achieved a marked effect in patients with hepatic encephalopathy. In the future, the research on intestinal flora in patients with hepatic encephalopathy can be deepened to provide better regimens for the treatment of hepatic encephalopathy.

The development and progression of nonalcoholic fatty liver disease (NAFLD) have complex potential mechanisms. The traditional “two-hit” pathophysiological theory has been challenged, and in recent years, an increasing number of studies have been performed to investigate the interaction between insulin resistance, adipokines, and other unknown pathogenic factors in various organs. This article summarizes the factors of the liver, intestinal tract, hypothalamus, and extracellular cysts, as well as genetic factors, with an emphasis on the synergistic mechanism of action of the liver and extrahepatic organs in the pathogenesis of NAFLD, in order to provide a reference for obtaining new insights into NAFLD regulatory network and determining new targets for the prevention and treatment of NAFLD.

As a novel form of programmed cell death different from cell necrosis, apoptosis, and autophagy discovered in recent years, pyroptosis is characterized by cell membrane rupture and release of cell contents and proinflammatory factors mediated by gasdermin, thus leading to cell death. Pyroptosis signaling pathways can be classified into classical pathways dependent on caspase-1 and non-classical pathways dependent on caspase-4/5/11; the activation of caspase-1 in classical pathways depends on the function of inflammasome, while the direct activation of caspase-4/5/11 is observed in non-classical pathways, which leads to the lysis of gasdermin D and induce the formation of membrane pores, the maturation and release of interleukin-1β and interleukin-18, and the rupture of cell membrane to cause pyroptosis. Latest research has shown that pyroptosis plays an important role in the development and progression of chronic liver diseases. This article introduces the mechanism of pyroptosis and summarizes the role of pyroptosis in the development and progression of nonalcoholic fatty liver disease, alcoholic liver disease, viral hepatitis, liver cirrhosis, and hepatocellular carcinoma, in order to provide new ideas and methods for the prevention and treatment of liver diseases in clinical practice.

Objective To investigate the methods and results of lateral leg propeller pedicled flaps based on multi-perforators for coverage of soft-tissue defects on the foot and ankle.Methods From May,2012 to June,2013,8 patients with soft-tissue defects were treated,including 5 cases by trauma,2 cases by chronic unlcers,1 case by infection on the foot and ankle with exposed osseous and tendinous.Lateral leg propeller pedicled flaps based on multi-perforators were elevated and rotated with the angle from 150° to 180° for coverage of soft-tissue de-fects.Flap size ranged from 15.0 cm × 7.0 cm to 23.0 cm × 9.0 cm.Skin graft was applied to cover the donor sites.After the operation,the blood supplies of flaps were observed severely over 10 days.Questionnaire of the flap aesthetic satisfactory and AOFAS evaluation were performed in 7 patients during fellowed-up periods.Results Seven flaps were all survived well,1 flap had partial marginal skin necrosis on the distal,which was managed with surgical debridement,and wound healed in 1 month.Seven patients had a mean of 10.7 months' fellowed-up periods.The flaps had like-like appearance,good contour,and high aesthetic satisfactor (100％).The mean AOFAS score was 90.5.Conclusion Lateral leg propeller pedicled flaps based on multi-perforators can supply the blood of the larger volume of tissue,which can be safely sustained to repair distal and larger defects on the foot and ankle.

Objective To investigate the methods and results of perforator pedicled flaps by anastomosis of superficial veins for reconstructing the extremity defects.Methods From February, 2012 to September, 2012, a total of 14 patients with traumatic skin and soft tissue and artery defects in extremities were repaired by perforator pedicled flaps anastomosed superficial veins with the recipient vessels.Fourteen flaps were based on five kinds of perforator arteries, the posterior interrosseous artery in 5 cases, the ulnar artery in 3 cases, the metacarpal artery in 2 cases, the peroneal artery in 3 cases, the lateral supramalleolar artery in 2 cases, the ulnar artery in 2 cases,and the posterior interrosseous artery in 1 case.After the operation, the blood supplies of flaps were observed severely,postoperative flap swelling were evaluated by edema level classification.After 1 month the blood flow of vein anastomosis were examed by color Doppler ultrasound.Questionnaire of the flap aesthetic satisfactory were performed during fellow-up periods.Results Twelve flaps were all survived well, 2 flaps had partial marginal skin necrosis in the distal, which was managed with surgical debridement, and wound healed in 1 month.Flap swelling were light, edema level classification were one degree in 4 cases,two degree in 10 cases postoperation 7 days, one degree in 11 cases and two degree in 3 cases, after 6 months.Color Doppler ultrasound examinations showed 9 vein anastomosises were all bypassed well.Eleven cases had 6-12 months' fellow-up periods.The flaps had like-like appearance, good contour, high aesthetic satisfactory.Conclusion Perforator pedicledr flaps by anastomosis of superficial veins can reduce the flap venous pressure obviously, avoid transientvenous venous congestion, improve the survival quality of the flap.It's a safe and effective method for soft tissue coverage of traumatic extremity wounds.

OBJECTIVETo investigate the clinical effect of anastomosis of superficial veins for improving the drainage of perforator propeller flaps.

METHODSFrom Sept. 2011 to Dec. 2012, 11 cases with soft tissue defects and chronic ulcer wound at extremities were treated with adjacent perforator propeller flaps, which were pedicled by the peroneal artery(5 cases), or the lateral supramalleolar artery(3 cases), or the ulnar artery (2 cases), or the posterior interrosseous artery (1 case). The wound size ranged from from 3.0 cm x 2. 5 cm to 11. 0 cm x 4. 0 cm, and the falps size ranged from 6 cm x 3 cm to 21 em x 5 cm. One superficial vein in all the flaps was anastomosed with superficial vein in the recipient area. The blood supply of the flaps were recorded after operation 1 - 3 months after operation, the fluency of anastomosed vein was detected by color Doppler ultrasound. Flap swelling evaluations were performed in early 3 months and later 3 - 6 months, and the results were classified into 4 grading degrees. 6 months later, Questionnaire of the flap aesthetic satisfactory was performed for seven patients during follow-up period.

RESULTS9 flaps survived completely, two flaps had partial marginal skin necrosis in the distal end, which were both managed with surgical debridement, and both wounds healed in two months. 9 cases were followed up for more than 12 - 19 months. The early rsults of flap swelling evaluations were: I degree 0 case, II degree 8 cases, III degree 3 cases, IV degree 0 case, and the later results were: I degree 7 cases, II degree 4 cases, III degree 0 case, IV degree 0 case. The flaps had ideal appearance, good contour, and high aesthetic satisfactory (100%). The mean flap survival area rate of veins anastomosed was (98. 6 ± 9. 7) %.

CONCLUSIONSPerforator propeller flaps with anastomosis of superficial veins can improve the flap venous drainage, avoid transient venous venous congestion, so as to increase the flap survival. It is an effective way for improving the vein drainage.
