Objective: To investigate the effect of TACE combined with C-arm CT-guided microwave ablation (MWA) in treatment of primary hepatic carcinoma (PHC) on special site. Methods: Totally 46 patients with PHC on special sites were treated with TACE combined with C-arm CT-guided MWA. CT and MRI of the liver was performed 1 month after operation to evaluate the therapeutic effect. Results: The operations were successfully performed in all 46 patients, including 51 times ablation, 37 patients underwent one time, 4 underwent two times and 2 patients underwent three times of ablation (on average 1.4 times ), and the ablation time was 3-5 min (on average 4 min). After operation, symptoms of abdominal pain, nausea, vomiting and fever etc. were noticed in 21 patients and relieved after symptomatic treatment. No serious adverse reaction occurred. One month after operation, complete necrosis of the tumor was detected in 44 cases, volume reduction ≥10% was found in 4 cases, tumor stable was observed 2 cases, while no tumor progressive case was found. All patients were alive so far. Conclusion: TACE combined with C-arm CT-guided MWA is effective and safe in treatment of PHC on special site.

OBJECTIVE: To assess the effect for local sensory to preserve great auricular nerve in the parotidectomy. METHOD: It was a prospective study. Eighy-one patients who underwent parotidectomy were randomly divided into 2 groups, preserving the great auricular nerve group and no preserving the great auricular nerve group. They were tested with the subjective and objective sensory function testing in 3, 6, 9, 12 months after operation. We assessed the result. RESULT: In the subjective sensory function testing, the result of the preserving the great auricular nerve group was better than no preserving the great auricular nerve group. In the objective sensory function testing, the result of the preserving the great auricular nerve group was obviously better than no preserving the great auricular nerve group. There was significant difference between the 2 groups (P<0.05). CONCLUSION It was effective for recovering the sensory function that we preserved the great auricular nerve in the parotidectomy.

Objective To explore the mechanism of LMWH therapy for SAP.Methods 48 wistar rats were random divided into 3 groups,sham group(S group),severe acute pancreatitis group(SAP group)and LMWH therapy group(H group).Serum amylase,IL-6,acinar cell apoptosis and the activity of NF-κB were detected and compared.Results The expression of amylase and IL-6 in SAP group was significantly higher than that in H group(P＜0.01).The apoptosis index of acinar cell in SAP group wag significantly lower than that in H group(P＜0.01),while the activity of NF-κB in SAP groupwas stronger than that in H group.Conclusions LMWH therapy may ameliorate SAP by inducing acinar cell apoptosis through suppressing the activity of NF-κB.

Objective:To study the protective effect of alendronate combined with Lactobacillus rhamnosus on bone loss in ovariectomized mice.Methods:Fifty female C57BL/6 mice were divided into 5 equal groups ( n=10). Ovariotomy was performed in groups A, B, C and D while a sham operation was performed in group E. Group A was subjected to combined administration of alendronate and Lactobacillus rhamnosus, group B to administration of alendronate, group C to administration of Lactobacillus rhamnosus, and groups D and E to administration of physiological saline only. At 3 months after operation, all the mice were sacrificed to harvest their femurs. Micro CT scanning was performed to detect the bone mineral density (BMD), trabecular relative volume, bone surface area/bone volume, and trabecular thickness and number of trabecular bone. Three-point bending test was used to detect the maximum load, stiffness, ultimate load, Young＇s modulus, and fracture energy. Osteocalcin and alkaline phosphatase levels were measured using blood samples from the mice eyeballs. The 2 groups were compared in terms of all the above indexes. Results:The BMD [(669.87±67.87) mg/cm 3], maximum load [(14.35±0.75) N] and fracture energy [(1,497.43±38.29) J/m 2] in group A were significantly higher than those in group B [(520.07±9.01) mg/cm 3, (11.94±0.82) N and(1,277.61±35.12) J/m 2] and group C [(388.15±25.61) mg/cm 3, (11.10±0.93) N and (1,115.27±63.24) J/m 2] (all P<0.05). The osteocalcin level in group A [(22.25±1.78) ng/mL] was significantly higher than that in group B [(19.08±1.45) ng/mL] and group D [(19.33±1.66) ng/mL] (both P<0.05). The alkaline phosphatase level in group A [(83.21±9.69) ng/mL] was significantly lower than that in group C [(113.16±14.44) ng/mL] and group D [(137.96±14.01) g/mL] (both P<0.05). Conclusion:Alendronate combined with Lactobacillus rhamnosus may play a synergistic role in prevention of bone loss in ovariectomized mice, because combined administration of the two is more effective than administration of either of the two.

Background::The calcineurin inhibitor (CNI)-based immune maintenance regimen that is commonly used after renal transplantation has greatly improved early graft survival after transplantation; however, the long-term prognosis of grafts has not been significantly improved. The nephrotoxicity of CNI drugs is one of the main risk factors for the poor long-term prognosis of grafts. Sirolimus (SRL) has been employed as an immunosuppressant in clinical practice for over 20 years and has been found to have no nephrotoxic effects on grafts. Presently, the regimen and timing of SRL application after renal transplantation vary, and clinical data are scarce. Multicenter prospective randomized controlled studies are particularly rare. This study aims to investigate the effects of early conversion to a low-dose CNI combined with SRL on the long-term prognosis of renal transplantation.Methods::Patients who receive four weeks of a standard regimen with CNI + mycophenolic acid (MPA) + glucocorticoid after renal transplantation in multiple transplant centers across China will be included in this study. At week 5, after the operation, patients in the experimental group will receive an additional administration of SRL, a reduction in the CNI drug doses, withdrawal of MPA medication, and maintenance of glucocorticoids. In addition, patients in the control group will receive the maintained standard of care. The patients’ vital signs, routine blood tests, routine urine tests, blood biochemistry, serum creatinine, BK virus (BKV)/cytomegalovirus (CMV), and trough concentrations of CNI drugs and SRL at the baseline and weeks 12, 24, 36, 48, 72, and 104 after conversion will be recorded. Patient survival, graft survival, and estimated glomerular filtration rate will be calculated, and concomitant medications and adverse events will also be recorded.Conclusion::The study data will be utilized to evaluate the efficacy and safety of early conversion to low-dose CNIs combined with SRL in renal transplant patients.Trial registration::Chinese Clinical Trial Registry, ChiCTR1800017277.

Objective     To explore the treatment method of congenital heart disease (CHD) with pulmonary artery hypertension (PAH) in infants with Down syndrome (DS). Methods     The clinical data of 60 CHD patients with PAH from March 2015 to August 2016 in our hospital were retrospectively analyzed. There were 30 infants with DS classified as a DS group (trial group, 17 males and 13 females with a mean age of 1.15±0.25 years) and the other 30 patients without DS were classified as a control group (20 males and 10 females with a mean age of 1.24±0.30 years). All the patients underwent surgical treatment and fasudil combined with sildenafil were used to prevent pulmonary hypertension crisis postoperatively. Results     There was no significant difference in cardiopulmonary bypass time, aortic cross-clamping time, modified ultrafiltration time and the incidence of postoperative respiratory complications between the two groups. The pulmonary systolic blood pressure significantly decreased at 24 h after operation in the two groups (both P<0.05). The arterial oxygen pressure and oxygenation index of the trial group were lower than those of the control group at 6 h after operation (both P<0.05). The mechanical ventilation time and intensive care time of the trial group were significantly longer than those of the control group (P=0.007 and P=0.000, respectively). There were no reoperations or early death. Conclusion     The effects of surgical repair of CHD with PAH in infants with DS are satisfactory by grasping the indication, protecting lung function and controlling PAH in the early postoperative period, although there is a high incidence of pulmonary complications.

Hypoxia is one of the factors restricting the survival of people at high altitudes, which can cause various symptoms such as vomiting, diarrhea, palpitations, shortness of breath and acute coma. About 80% of patients with acute mountain sickness have at least one symptom of a gastrointestinal distress (e. g., anorexia, nausea, diarrhea, vomiting, etc.). The pathological characteristics, pathogenesis and drug treatment of intestinal injury caused by high-altitude hypoxia were studied, which is conducive to the diagnosis and treatment of plateau gastrointestinal diseases. Therefore, by summarized relevant literature and systematically expounds the related researches on intestinal damage caused by high altitude hypoxia. We summarized the changes of intestinal morphology, intestinal cells, intestinal flora and other intestinal homeostasis caused by high altitude hypoxia, the mechanism of intestinal inflammation and oxidative damage, and the treatment of traditional Chinese medicine, which provide reference and information for reference for scientific research workers and clinicians.
