BACKGROUND:Hepatic cirrhosis may adversely affect the outcome of major orthopedic surgery, such as total hip arthroplasty. Peri-operative treatment is the chal enge for al orthopedic surgeons.
OBJECTIVE:To analyze the safety and feasibility of hip replacement surgeries in patients with hepatic cirrhosis.
METHODS:Thirteen patients with hepatic cirrhosis that underwent hip replacement were retrospectively analyzed to evaluate the treatments and their efficacy before and after replacement.
RESULTS AND CONCLUSION:Al 13 surgeries were successful y performed. Al cases were fol owed up for more than five months and were graded according to Child-Pugh Criteria for hepatic functional reserve preoperatively and postoperatively. Five cases of the seven preoperative grade A cases preserved grade A postoperatively during a two-week observation, while another two cases rose to grade B and needed hepatic conservation treatment before discharge. Two cases of the six preoperative grade B cases rose to grade C with developed jaundice and ascites. Of the two, one even suffered a complication of upper gastrointestinal hemorrhage 5 days after surgery. Somatostatin and proton pump inhibitors were administered to stop bleeding. Al cases gained a satisfying recovery. Harris hip score at fol ow-up showed favorable hip function. Hip replacement is safe and feasible for patients with hepatic cirrhosis when ful evaluation of hepatic function and appropriate perioperative management are ensured.

The present paper is aimed to study the fractal spectrum of the cerebral computerized tomography in 158 normal infants of different age groups, based on the calculation of chaotic theory. The distribution range of neonatal period was 1.88-1.90 (mean = 1.8913 +/- 0.0064); It reached a stable condition at the level of 1.89-1.90 during 1-12 months old (mean = 1.8927 +/- 0.0045); The normal range of 1-2 years old infants was 1.86-1.90 (mean = 1.8863 +/- 4 0.0085); It kept the invariance of the quantitative value among 1.88-1.91(mean = 1.8958 +/- 0.0083) during 2-3 years of age. ANOVA indicated there's no significant difference between boys and girls (F = 0.243, P > 0.05), but the difference of age groups was significant (F = 8.947, P < 0.001). The fractal dimension of cerebral computerized tomography in normal infants computed by box methods was maintained at an efficient stability from 1.86 to 1.91. It indicated that there exit some attractor modes in pediatric brain development.

Objective To establish gastric bypass surgery model with SD rat and analyze the influence factors and preventive measures so as to accumulate experience and skills for further developing gastric bypass surgery model on diabetic rat( GK rat) . Methods Gastric by-pass surgery was operated on 30 SD rats. Summarized modeling experience and analyzed various factors affecting modeling success. Results 17 rats weresuccessfully survived after surgery and 13 failed, with the mortality rate 43. 3%. Three rats died during operation, including two for anesthesia and one for heart failure;one died due to anastomotic bleeding two hours after surgery. Eight died in the third day after surgery, including two for infection, two for intestinal necrosis, four for anastomotic stenosis or obstruction. One died because of anastomotic leakage caused by mistaking and satiety the fifth day after surgery. There were no other complications such as wound dehiscence occurred in this group . Conclusion Establishing models of gastric bypass surgery with SD rats which is regarded as pre-experiment of building models of gas-tric bypass surgery with GK rats is economical and feasible. Anesthesia and perioperative management, surgical techniques and infection pre-vention and control are the main factors affecting modeling. The survival rate of rat model could be increased if related factors well controlled.

Objective To investigate changes in serum levels of Th22 cell ? related cytokines and complements in patients with drug eruption before and after treatment, and to explore their possible roles in the occurrence and development of drug eruption. Methods This study included 35 patients with drug eruption, and 35 sex?and age?matched healthy controls. Five milliliters of peripheral blood samples were collected from the controls and patients before and after treatment. Enzyme?linked immunosorbent assay(ELISA)was performed to measure serum levels of interleukin 22(IL?22)and IL?13, and the cytometric bead array(CBA)system was used to determine serum levels of tumor necrosis factor?α(TNF?α) and complement components C3a, C4a and C5a. Results Before treatment, the patients with drug eruption showed significantly higher serum levels of IL?22(40.85 ± 14.56 vs. 29.09 ± 8.66 ng/L, t=5.549, P<0.05), IL?13(869.94 ± 463.39 vs. 372.92 ± 151.75 ng/L, t=6.071, P<0.05), TNF?α(1.03 ± 0.64 vs. 0.44 ± 0.31 ng/L, t=4.321, P<0.05), complement C3a(55.21 ± 32.98 vs. 42.44 ± 14.26 ng/L, t=2.832, P<0.05), C4a(285.11 ± 123.91 vs. 237.00 ± 63.57 ng/L, t=2.257, P<0.05), and C5a(279.68 ± 127.72 vs. 215.98 ± 65.38 ng/L, t=2.495, P<0.05)compared with the controls. After treatment, the serum levels of IL?22, IL?13, TNF?α, complement C3a, C4a and C5a in patients decreased to(32.72 ± 11.77)ng/L,(456.21 ± 123.22)ng/L,(0.64 ± 0.39)ng/L,(45.47 ± 21.11)ng/L,(241.86 ± 84.12)ng/L and(239.61 ± 103.51)ng/L respectively, with a significant difference between the pretreatment and posttreatment values of these proteins(t = 4.443, 5.197, 3.572, 3.213, 2.728 and 4.772, respectively, all P ≤ 0.01). Additionally, the serum levels of IL?22 and IL?13 were still significantly higher in the patients than in the controls(both P < 0.05), while there were no significant differences in the serum levels of TNF?α, complement C3a, C4a or C5a between the patients and controls after treatment(all P > 0.05). Correlation analysis showed positive correlations between complement C3a and C4a serum levels(r = 0.660, P < 0.05), between C3a and C5a serum levels(r = 0.404, P < 0.05), between C4a and C5a serum levels(r = 0.501, P < 0.05), and between IL ? 22 and TNF ? α serum levels(r = 0.573, P = 0.005), but negative correlations between IL ? 22 and complement C3a serum levels(r = -0.490, P = 0.005), in patients before treatment. Conclusion The activation of Th22 cell?related cytokines and complements may play important roles in the occurrence and development of drug eruption, and IL?22 may participate in the regulation of complements.

Objective To investigate the clinical features,pathogenesis,diagnosis and treatment of neonatal cerebral infarction(NCI)in order to have a further understanding of its clinical features,to enhance therapeutic effica﹣cy and to improve prognosis. Methods The clinical history,head magnetic resonance imaging( MRI)+ diffusion Weighted imaging(DWI)data and folloW-up results of 39 neonates With NCI admitted into the Department of Neonato﹣logy,Gaozhou People's Hospital and the Second Affiliated Hospital of Shantou University Medical College from January 2013 to March 2018 Were retrospectively analyzed. Results All the 39 children Were diagnosed as NCI by MRI +DWI,among Which 30 cases(76. 92%)Were full-term infants,and 9 cases(23. 08%)Were premature infants,in Which 61. 54%(24/39 cases)Were males,and 17 cases(43. 59%)Were performed With emergency cesarean section because of umbilical cord around neck,intrauterine distress or maternal pregnancy hypertension respectively. TWenty-five patients(64. 10%)had the history of perinatal hypoxia. The presentation of MRI shoWed 32 cases(82. 10%)of ischemic cerebral infarction and 7 cases(17. 90%)of hemorrhagic cerebral infarction,While middle cerebral artery and its branches Were more susceptible to NCI With a left hemisphere predominance. Sixteen patients(41. 03%)developed convulsions. TWo patients died of purulent meningoencephalitis associated With NCI. One patient gave up treatment in the neonatal period and died 2 days after discharge. One patient died of cerebral palsy and pneumonia at the age of 11 months. Nine cases(31. 03%)developed cerebral palsy,and 2 patients developed speech disturbance so they could not express complex sentences. Conclusions Perinatal hypoxia and emergency cesarean section may be closely related to the incidence of NCI. NCI resulting from purulent meningoencephalitis is more severe and has a Worse prognosis. Considering the facts that NCI usually does not have specific clinical manifestations in the early stage,MRI +DWI,as the gold standard for the diagnosis of NCI,could be performed to facilitate early diagnosis and intervention.

Obesity and its complications, such as type 2 diabetes, hypertension, hyperlipidemia, nonalcoholic fatty liver, are serious global public health problems. Endoscopic sleeve gastroplasty (ESG) can reduce the length and width of the stomach by simulating the anatomical structure of surgical sleeve gastrectomy to reduce the capacity of the stomach, and is safe and effective to reduce weight. ESG has the advantages of non- invasiveness, no gastrectomy, repeatability, simple operation, no incision scar, few complications, short hospital stay and quick postoperative recovery. As an intermediate means of medical treatment and surgery, ESG provides a new method for weight loss for obese patients who cannot tolerate or are unwilling to undergo surgery. Herein we trace the origin of ESG, analyze the unique advantages of ESG suture, explore the technical improvement in the development of ESG, and briefly describe the weight reduction effect of ESG and compare the curative effect of ESG with laparoscopic sleeve gastrectomy. ESG has undergone rapid development and maturity but also faces such challenges as the lack of established standard procedures, unclear weight reduction mechanism, and clarification of the indications for operation. Still, ESG is expected to become the mainstream technique for weight reduction.
