In recent years, through the measurement and analysis of size ratio(SR), inflow angle (IFA), volume-to-ostium ratio(VOR), flow angle(FA), parent-daughter angle(PDA), A1- A2 diameter ratio(A1/A2), a ratio of aneurysm volume to bounding sphere volume(AVSV), a ratio of aneurysm surface to bounding sphere surface (AASA), some international scholars assessed aneurysm rupture risk, and had made some preliminary progress. Research showed that the geometry parameters had the objective significance for the evaluation of the risk of aneurysm rupture, and the bigger the SR, IFA, VOR, FA, A1/A2, AVSV, AASA, the easier the rupture of aneurysms. The smaller the PDA, the easier the rupture of the aneurysms.

Objective To investigate the death of MHD patients with different blood phosphorus variability.Methods The clinical data of seventy-four cases of MHD patients with more than 3 months dialysis age in the hemodialysis center of Chaozhou Central Hospital from January 2014 to December 2016 were retrospectively analyzed.The general data and laboratory biochemical indexes were collected and according to the difference in coefficient of variation (CV),the patients were divided into two groups:high blood phosphorus variability group (CV≥0.226 mmol/L) and low blood phosphorus variability group (CV ＜0.226 mmol/L).The relationship between the coefficient of variation and all-cause mortality and cardiovascular mortality in MHD patients was analyzed.Results Among all selected patients,all-cause mortality rate was 22.9％ (17/24),12.2％ (9/74) died of cardiovascular disease,and the all-cause mortality 34.2％ (13/38)in the high blood phosphorus variability group was significantly higher than that in the other one1 1.1％ (4/36) (x2=5.574,P＜0.05);but there was no significant difference between the two groups in cardiovascular disease mortality (X2 =0.962,P＞0.05).And there was no significant difference between the serum phosphorus standard group and the substandard group in the all-cause mortality and the cardiovascular disease mortality (x2 =0.389,0.065,P ＞ 0.05).There was no significant difference in the cumulative survival rate between the patients in the serum phosphorus standard group who experienced all-cause death and cardiovascular disease death and the patients in the substandard group (P＞0.05).In the high blood phosphorus variability group,patients who reached serum phosphorus standard had higher total mortality rate and cardiovascular disease mortality rate,compared with patients who achieved serum phosphorus standard or experienced low phosphorus deficiency in the low blood phosphorus variability group (x2=0.211,0.197,P ＞0.05).Kaplan/Meier analysis showed that the cumulative survival rates of all patients with all-cause death and cardiovascular death in the high blood phosphorus variability group were significantly lower than those in the low level group (P＜ 0.05).Conclusion All-cause mortality and cardiovascular disease mortality are high in MHD patients with large variability in blood phosphorus,and the degree of blood phosphorus variation is helpful to predictthe death of MHD patients.

Objective To observe the effects of acupuncture therapy with finger on back-shu point on acid reflux and lower esophageal sphincter pressure (LESP) of the patients with gastroesophageal reflux disease (GERD). Methods Totally 120 patients of GERD were randomly divided into treatment group and control group through random number table method, 60 cases in each group. Patients in the treatment group were treated with the acupuncture therapy with finger on back-shu point, and patients in control group were treated with lansoprazole tablets and dispersible mosapride citrate for two weeks. Total percentage of acid reflux time, the long time acid reflux episodes, and the longest acid reflux time of two groups were observed six months after the treatment. At the same time, the LESP variation of two groups was followed up six months after the treatment. Results The total percentage of acid reflux time, the long time acid reflux episodes, and the longest acid reflux time decreased significantly in all patients after treatment (P<0.01), while the comparison between groups showed no significant difference (P>0.05). After treatment, LESP of two groups was significantly improved (P<0.05) than before treatment. After stopping treatment half a year, the treatment group had obvious difference (P<0.05) compared with before treatment, while the control group had no significant difference (P>0.05). Conclusion The acupuncture therapy with finger on back-shu point can reduce acid reflux, and achieve the goal of treatment of GERD by improving the lower esophageal sphincter pressure. The duration of improving LESP is longer.

Objective: To discuss the functional recovery after recurrent laryngeal nerve injury (RLNI) on different electromyography thresholds during thyroid surgery. Methods: The prospective experimentally were induced in 12 acute recurrent laryngeal traction animals (porcine) from December 2014 to December 2015, the amplitude and latency of electromyography, even time course during RLNI and recovery of 24 recurrent laryngeal nerves(RLN) were continuous intraoperative neuromonitoring(IONM), including 12 RLN releasing traction after 50% amplitude decrease (AD) and other 12 RLN after 70% AD. The IONM data and postoperative laryngoscopy result of 1 119 thyroid cancer patients, involved 237 male and 882 female, aged 45.2 years in average, who underwent thyroidectomy in Department of Thyroid Surgery, China-Japan Union Hospital Affiliated to Jilin University from July to December in 2016 were analyzed retrospectively. Results: The porcine model of traction lesion showed that the time of 50% AD was (59±4) s, latency increase (LI) was (8± 4)%, was recovered in 10 minutes; the time of 70% AD was (75±6)s, LI was (11±5)% , was recovered (43±23)% of baseline even during 20 minutes. Among the IONM of 1 632 recurrent laryngeal nerves in clinic, the mechanism of 64 RLNI is clear, including traction injury accounted for 62.5% (40/64), thermal injury was 12.5% (8/64), compression injury was 23.4% (15/64), clamp injury was 1.6% (1/64). When 50%≤AD <70% (8.8%), the rate of abnormal vocal fold movement (AVCM) was 8.8% (6/68), while AD≥70% (37.2%), the rate of AVCM was 37.2% (19/51), but LOS was 5/13. Conclusion Releasing the injury before AD≥50% in surgery, is a more effective indicator to avoid postoperative AVCM and promote nerve function recovery.

Biliary atresia is a rare infant disease that predisposes patients to liver transplantation and death if not treated in time. However, early diagnosis is challenging because the clinical manifestations and laboratory tests of biliary atresia overlap with other cholestatic diseases. Therefore, it is very important to develop a simple, safe and reliable method for the early diagnosis of biliary atresia. Herein, a novel NIR-II fluorescence probe, HZL2, with high quantum yield, excellent biocompatibility, low cytotoxicity and rapid excretion through the liver and gallbladder was developed based on the oil/water partition coefficient and permeability. A simple fecal sample after injection of HZL2 can be used to efficiently identify the success of the mouse model of biliary atresia for the first time, allowing for an early diagnosis of the disease. This study not only developed a simple and safe method for the early diagnosis of biliary atresia with great potential in clinical translation but also provides a research tool for the development of pathogenesis and therapeutic medicines for biliary atresia.
