Objective To study the effect of modified periocular injection on the pains induced by local application of drugs. Methods Sixty patients treated with periocular injection were divided randomly into experimental group and control group in equal number. The control group was treated with orthodox periocular injection,while experimental group with modified periocular injection, immersing the pinhead into lidocaine solution before injection.The pain level of patients was evaluated by self-designed pain scale. Result The pain level of modified periocular injection was lower than that of orthodox periocular injection statistically (Z=3.799, P<0.001).Conclusion Modified periocular injection can alleviate pains induced of local application of drugs obviously and increase their compliance,so it deserves clinically popularizing.

ObjectiveTo evaluate and compare the curative effect and the safety of sclerotherapy of venous malformation in children using absolute ethanol and pingyangmycin.MethodsEighty children with venous malformation were treated by sclerotherapy with absolute ethanol or pingyangmycin under general anesthesia during February of 2009 to May of 2011. Diagnostic criteria included the presence of a bluecolored lesion at birth,with gradual increase in its size associated with a positive postural test.MRI showed characteristic imaging features.Eighty patients were divided into two groups by randomization.Forty patients were treated with absolute ethanol,and the remaining 40 patients with pingyangmycin. The therapeutic effects and side effects were observed and recorded during a follow-up period of 6 to 24 months ( average 15 months).Treatment results weredividedinto four categories: cure, basiccure, effective, and ineffective,and the former three categories were considered effective in treatment.Chi-square test was used to compare the rate of effective treatment and rate of complications in these two groups.ResultsThe effective patients treated with absolute ethanol was 38 (95.0％,38/40),and the effective patients with pingyangmycin was 26(65.0％,26/40),x2 test ( x2 =11.25,P ＜ 0.01 ) difference was statistically significant.Eight patients developed skin necrosis; 4 patients serious local swelling,2 patients muscle fibrosis,1 patient cerebral embolism in the absolute alcohol group.Two patients developed postoperative fever and vomiting and 2 skin necrosis in the pingyangmycin group,the difference was statistically significant (x2 =12.29,P ＜0.01 ). ConclusionsSclerotherapyiseffectiveforthetreatmentofvenousmalformationsin children.Absolute ethanol is more effective,but associated with more complications,such as skin necrosis or as serious as cerebral embolism,than pingyangmycin.

Objective To analyze the epidemiological characteristics of malaria in Hechi City,Guangxi Zhuang Autono?mous Region from 2005 to 2015,so as to provide the evidence for formulating and adjusting measures of malaria elimination. Methods The data of malaria cases in 11 counties of Hechi City from 2005 to 2015 were collected and analyzed by using Micro?soft Office Excel 2003 and SPSS 17.0. Results A total of 160 malaria cases were reported in Hechi City from 2005 to 2015, and the annual average malaria incidence was 3.6 per million. There were 10 local recurrence cases(accounting for 6.25%,10/160)and 150 imported cases(accounting for 93.75%,150/160). For the etiology,Plasmodium vivax accounted for 51.87%(83/160)in these cases,P. falciparum accounted for 34.38%(55/160),P. ovale accounted for 1.25%(2/160),P. malariae account?ed for 5.00%(8/160),and the indeterminate accounted for 7.50%(12/160). During the period of 11 years,the malaria inci?dence first dropped and then rose. There were no local cases after 2009. However,an imported falciparum malaria death case was reported in 2010,a severe imported falciparum malaria case was reported in 2013 and another in 2015. A severe case of ma?ternal?neonatal vivax malaria was reported in 2014. These cases were mainly distributed in 10 counties of Hechi City,with more young male adults who engaged in digging mining. More cases concentrated from April to August. Most of the reported malaria cases were imported,60.00%(96/160)of them returned from Africa and Southeast Asia,and 33.75%(54/160)from other do?mestic provinces. The median of the interval from symptom appearance to diagnosis was 5 d,and there was a significant differ?ence among the above years(c2=33.40,P<0.05). Conclusions Malaria is still an important public health problem in Hechi City,and the appropriate control measures and effective tools should be strengthened for malaria elimination. The key to consoli?date the achievements of malaria control is strengthening the malaria monitoring management of the floating population.

Objective To explore the effect and safty of interventional embolization of congenital arteriovenous fistula (CAVF) in the common femoral profounda artery in children.Methods Eight children (aged 6 to 14 years ;6 males and 2 females) with CAVF underwent interventional embolization From January 2006 and December 2010.Color Doppler sonography and DSA were performed on all patients.Arterial duplex imaging revealed the arteriovenous fistula in the common femoral profounda artery and DSA further confirmed the presence of an AVF over the common femoral profounda artery via the other vein.All children were treated with interventional embolization therapy by the injection ofcoils or ethanol through a microcather.It was necessary to performed repeated interventional embolization if the lesion was not obliterated in 4 weeks.All patients were followed-up from 6 months to 2 years and the clinical symptoms were observed.Results Arteriograpy can clearly demonstrate the femoral profounda artery and its branches as well as the fistula.Ten interventional embolization procedures were performed.Forty seven coils were deployedduring the procedure and seven ethanol embolization procedures were performed.Post-procedural angiography revealed complete occlusion in 8 patients.No major complications such as ectopic coil embolization,tissue necrosis,peripheral nerve palsy or cardio-pulmonary collapse were found.The abnormal AVFs were embolized completely in 7 cases after only one therapy and there was no recurrent disease in the 6 months to 2 years follow-up.Some tiny AVFs were still found in another case which underwent three additional treatments.However,the clinical symptoms were under control.Conclusion Interventional embolization is a safe and effective therapeutic method for CAVF of the common femoral profounda artery in children and it might become the primary treatment option.

Objective To explore the efficacy of simultaneous reconstruction of composite tissue defects in two adjacent metacarpophalangeal joints of hand by split the 2nd toes.Methods From December 2006 to December 2011,the second toe composite flap pedicled with the dorsalis pedis artery-first,second metatarsal dorsal artery-dorsal artery were designed,and split it into the second metatarsophalangeal joint composite flap pedicled with the dorsalis pedis artery-first dorsal metatarsal artery-tibial artery and the proximal interphalangeal joint composite flap pedicled with dorsalis pedis artery-second dorsal metatarsal arteryfibular dorsal artery.Then they were used to repair composite tissue defects in two adjacent metacarpophalangeal joints of hand at the same time after reconstruction.Results This group includes 14 metacarpophalangeal joints of 7 cases,twelve joints was successful,two joints of 1 case to give up because the first dorsal metatarsal artery variation.At 6-24 months follow-up study in 12 out of 14 cases showed that there was no joint degeneration in X-ray manifestation and the recovering of joint function was satisfying.According to the function evaluation standard of reconstraction of thrumb and finger issued by Hand Surgery Society Chinese Medical Association,the excellent and good rate was 83.3％.Conclusion It is feasible to reconstruct of composite tissue defects in two adjacent metacarpophalangeal joints of hand at the same time by split the 2nd toes,and can effectively improve the functions of injury metacarpophalangeal joint.

Objective To explore the ways to decrease the postoperative complications of pancreaticoduodenectomy. Methods Thirty-four patients who underwent pancreaticoduodenectomy between January 1998 and December 2004 were reviewed retrospectively. A duct-to-mucosa pancreaticojejunostomy was performed mostly for patients, and an end-to-end pancreaticojejunal invagination for 5-patients with a soft pancreas and a small pancreatic duct. The end-to-side hepaticojejunostomy and the Roux-en-Y reconstruction of gastrointestinal continuity were performed for all patients. Results The hospital mortality was zero. The postoperative complications occurred in the form of wound infection was 4(12%), delayed gastric emptying was 1(3%), pneumonia was 1(3%), intra-abdominal collections was 1(3%) and pancreaticojejunostomy leak was 1(3%). In 1 patient with pancreaticojejunostomy leak, the closure was achieved with the conservative treatment. Intra-abdominal bleeding, intra-abdominal abscess and other anastomotic leakage were not seen in any of patients. The median follow-up was 21 months (ranging from 6 months to 5 years), none of patients had clinical evidence of steatorrhea, bile reflux gastric disease, anastomotic ulcer, retrograde cholangitis and dumping syndrome, there was no new case of diabetes. Conclusions Proper method of reconstruction produces encouraging results in decreasing the complications after pancreaticoduodenectomy.

ObjectiveTo investigate the effect of endovascular stent with or without coil graft on intracranial wide-necked aneurysms. Methods12 cases with intracranial wide-necked aneurysms, among whom, 10 cases were treated with stents and coils, 2 C4 aneurysms were treated with graft stent, were analyzed retrospectively. ResultsOf the 10 cases who were treated with stents and coils, 8 patients were completely occluded and other 2 patients were incompletely (>95%) occluded. 2 cases accepted graft stent were obliterated. Follow-up with angiography in 10 patients for 3～12 months revealed that all the aneurysms were completely occluded. 1 patient among them died. ConclusionEndovascular stent with or without coil graft is effective on intracranial wide-necked aneurysms.

Objective To investigate the effects of interleukin-18 ( IL-18 ) on M cells of intestinal mucosa in acute pancreatitis (AP) in rats. Methods Seventy SD rats were divided into seven groups: AP 6 hour group, 12 hour group, 24 hour group, IL-18 6 hour group, 12 hour group, 24 hour group, and control group at random. The models of AP were established. Serum, pancreatic tissue, and ileal mucosa were harvested. Serum amylase, glutamate pyruvate transaminse, total bilirubin, endotoxin, IL-27, and TNF-α were detected. Pathologic changes of pancreatic tissue and ileal mucosa were observed. The protein with reverse transcription-polymease chain reaction (RT-PCR). Results The level of serum TNF-α increased obviously in IL-18 6 hour group, 12 hour group, and AP group. The level of serum IL-27 increased in IL-18 6 hour group and AP group and back to normal in IL-18 24 hour group. The in IL-18 group than AP group (P < 0. 05 ). Conclusions IL-18 may affect M cells function and play important roles in intestinal barrier in acute pancreatitis.

Objective:To figure out variety of the plasma level of Alpha-1-Antitrypsin(α1-AT) in patients who undergo AKI following cardiopulmonary bypass(CPB), and whether this biomarker serve as a competent predictor.Methods:We recruited 75 patients undergoing cardiac surgery with CPB from January 2018 to January 2019. Patients were categorized into two groups according to the development of AKI. The relationship between plasma concentration of α1-AT and renal injury in two groups was analyzed.Results:27 patients in the AKI group were aged (54.3±12.2)years old, including 15 males and 12 females, the time of cardiopulmonary bypass was(133.5±34.7)min. In the non-AKI group, 48 cases were aged(47.7±11.3)years old, including 26 males and 22 females, and the time of cardiopulmonary bypass was(133.5±34.7)min. α1-AT was significantly decreased in AKI group at 1 h after operation[(0.53±0.53)g/L vs. (1.46±0.91)g/L, P<0.05]compared with the non-AKI group. The sensitivity and specificity of α1-antitrypsin level at 1h after operation was the highest when α1-AT was 0.675 g/L. CPB time ( OR=5.890, 95% CI: 1.078-32.173) and age ( OR=4.427, 95% CI: 1.113-17.614) were independent risk factors for AKI after surgery, and α1-AT at 1h after CPB ( OR=0.084, 95% CI: 0.021-0.333) were protective factors after operation. Conclusion:Increased concentration of α1-AT after cardiopulmonary bypass at early time is a protective factor for AKI and the concentration of α1-AT in plasma could be used as an early biomarker of AKI after CPB.
