Recurrent intracerebral hemorrhage is a very serious cerebrovascular disease.Its incidence has shown a clear upward trend, and both disability and mortality have increased significantly compared to the first intracerebral hemorrhage. This article reviews the clinical classification, characteristics, risk factors, pathogenesis, and prognosis of recurrent intracerebral hemorrhage.

OBJECTIVE: To evaluate the clinical value of lidocain in the treatment of tinnitus through three routes of administration (intravenous, intratympanic and acupoint injection) by analyzing literatures. METHOD: Articles were collected through Hownet, Wanfang, VIP, Pubmed, SciVerse ScienceDirect, Springer and OVID, etc. The articles were strictly evaluated based on their quality. The Meta-analysis was performed to evaluate the outcomes by RevMan 5. 2 software. RESULT: A total of 16 articles with 1203 patients were enrolled in the analysis. Their tinnitus history ranged from 7 hours to 20 years. Assessment methods include tinnitus loudness levels, severity scales and subjective feelings. None of articles refer to maintaining time, instead of "short-term", "short" and so on. A total of 133 cases received intravenous injection and the effective rate was 73.4% (98 cases). 50 cases and 332 cases received intratympanic and acupoint injection respectively and their effective rates were 74.0% and 87.7%, respectively. The effective rate ranged from 42.4% to 58.3% in control group. Meta-analysis results indicate that all three routes of lidocaine administrations are more effective than conventional methods (P < 0.05). CONCLUSION Different routes of lidocaine administration have a good but short time effects on the tinnitus control. It can effectively reduce the time of tinnitus habituation as a complementary treatment. But its value still needs further evaluation.

Acute myocardial ischemia (AMI) was induced by occlusion of the left anterior descending (LAD) coronary artery in rats.AMI rats and normal rats were administered with protocatechuic aldehyde(Pal) at a single dose of 20 mg/kg through peritoneal injection.Concentrations of Pal,protocatechuic acid (PAC) and vanillic acid (VAC) in plasma were determined by HPLC to evaluate the effect of AMI on pharmacokinetics of Pal in rats.Pal was quickly metabolized to PAC,which was then methylated into VAC.Compared to the normal group,AUC_(0-∞) of PAC significantly increased from 14.01 ±3.11 to 22.31 ±4.96 μg·h/mL in AMI group (P ＜ 0.01),and AUC_(0-∞) of VAC markedly elevated from 19.64 ±4.36 to 38.76±5.75 μg·h/mL (P＜0.01).Both MRT of PAC and VAC increased (0.43 ± 0.08 h vs 0.27 ± 0.04 h,0.61 ± 0.11 h vs 0.38 ± 0.05 h,P ＜ 0.01).Metabolic ratio M/P of PAC increased from 1.43 ±0.31 to 1.77 ±0.22 (P ＜0.05).Results indicated that AMI status had great influence on pharmacokinetic behavior of Pal.Meanwhile,the level of methylation was greatly increased.

Objective To investigate the application value of the modified Overlap method in digestive tract reconstruction of totally laparoscopic total gastrectomy (TLTG).Methods The retrospective cohort study was conducted.The clinicopathological data of 50 patients with gastric cancer who underwent TLTG with Overlap anastomosis between January 2016 and December 2016 in the Tangdu Hospital of the Fourth Military Medical University were collected.Twenty-six patients using classic Overlap method and 24 patients using modified Overlap method were respectively allocated into the classic Overlap group and modified Overlap group.All the patients underwent D2 lymph node dissection.Patients in the classic Overlap group underwent totally laparoscopic catastalsis side-to-side esophagojejunostomy.During digestive tract reconstruction in the modified Overlap group,there was no esophageal transection before anastomosis,and gastric fundus traction fully exposed to the lower esophagus.Esophagus was spun anticlockwise,and a hole was opened at the left posterior esophageal wall.Transection of jejunum was 25 cm away from Treitz ligment,and opening a hole at mesenteric margin was 6 cm away from distal jejunum to transected end of jejunum.Esophagus-distal jejunum side-to-side anastomosis was done using 60 mm linear stapler,and then laterally closing openings and transecting esophagus.Observation indicators:(1) intra-and post-operative recovery:total operation time,time of esophagus-jejunum anastomosis,volume of intraoperative blood loss,number of lymph node dissected,time to anal exsufflation,cases with complications and duration of postoperative hospital stay;(2) follow-up and survival.Follow-up using outpatient examination and telephone interview was performed to detect the postoperative tumor-free survival and tumor recurrence or metastasis up to March 2017.Measurement data with normal distribution were represented as (x)±s and comparison between groups was analyzed using the independent-sample t test.Comparison of count data was analyzed using the chi-square test or Fisher exact probability.Results (1) Intra-and post-operative recovery:all the 50 patients underwent successful TLTG using Overlap method,without conversion to open surgery.Total operation time and time of esophagus-jejunum anastomosis were respectively (278.6± 14.9) minutes,(46.5 ± 4.4) minutes in the classic Overlap group and (253.3 ± 12.8) minutes,(20.4 ± 2.3) minutes in the modified Overlap group,with statistically significant differences between the 2 groups (t =5.459,22.482,P＜0.05).Volume of intraoperative blood loss,number of lymph node dissected,time to anal exsufflation,cases with complications and duration of postoperative hospital stay were respectively (73±25) mL,34±6,(2.7± 1.0) days,2,(9.7± 1.6) days in the classic Overlap group and (71 ± 22) mL,35± 5,(2.6± 1.3) days,2,(9.8± 1.5) days in the modified Overlap group,with no statistically significant difference between the 2 groups (t =0.175,-0.616,0.293,-0.217,P＞ 0.05).Two patients in the classic Overlap group were respectively complicated with esophagus-jejunum anastomotic fistula and pancreatic leakage,2 patients in the modified Overlap group were respectively complicated with pulmonary infection and subcutaneous emphysema,and they were improved by symptomatic treatment.(2) Follow-up and survival:41 of 50 patients were followed up for 3-15 months,with a median time of 7 months,including 20 in the classic Overlap group and 21 in the modified Overlap group.During follow-up,patients had tumor-free survival,without tumor recurrence and metastasis.Conclusion Compared with classic Overlap method,the modified Overlap method can simplify the anastomotic procedures,shorten operation time and achieve similar efficacy,and it is also a simple and effective method for digestive tract reconstruction after TLTG.

Moyamoya disease is a chronic progressive cerebrovascular disease. Its disability rate and lethality rate are higher. The direct and indirect revascularization can increase cerebral blood flow and reduce the occurrence of cerebral ischemia and cerebral hemorrhage. This article reviews the pathophysiological basis of its surgical treatment, surgical timing, indications, surgical treatment methods and efficacy.

OBJECTIVETo explore the molecular etiology for a Chinese family affected with isolated methylmalonic acidemia (MMA).

METHODSPotential mutations of MUT, MMAA and MMAB genes in the proband were screened by PCR and Sanger sequencing. The pathogenicity of identified mutations was analyzed using Polyphen2, SIFT, HSF, DNAMAN 6.0 and Swiss-PdbViewer4.1.0 software.

RESULTSTwo novel mutations of the MUT gene, including c.581C>T (p.P194L) and c.1219A>T (p.N407Y), were discovered in the proband, which were inherited respectively from his mother and father. Bioinformatics analysis suggested that both mutations were damaging. The affected codons P194 and N407, both located in the (beta, alpha) 8 barrel domain and to which the substrate methylmalonyl-CoA is bound, are highly conserved across various species. Both mutations can disrupt the space conformation of its protein product, affecting the function of the MCM protein.

CONCLUSIONThe novel mutations of MUT gene probably underlie the isolated MMA in this family.

OBJECTIVETo compare the short-term efficacy of modified medial (M-M) with traditional medial(T-M) approach in laparoscopic right hemicolectomy(LRHC)/or extended laparoscopic right hemicolectomy(ELRHC) for right or hepatic flexure colon cancer.

METHODSA comparative, retrospective study was performed that included all the patients scheduled for LRHC or ELRHC for right or hepatic flexure colon cancer between June 2013 and August 2014. The following factors of two groups were assessed: patient characteristics, operative details, pathology, and surgical outcomes.

RESULTSA total of 99 patients were evaluated, including 52 patients in the M-M group and 47 patients in the T-M group. Age, gender, body mass index, American Society of Anesthesiology(ASA) class, tumor location, diameter of tumor were not significantly different between the two groups. As compared to the T-M group, M-M group was associated with a significantly shorter operative time [(105.6±38.8) min vs. (138.2±39.5) min, P<0.05], less estimated mean blood loss[(38.4±12.4) ml vs. (87.2±24.6) ml, P<0.05] and lower intraoperative vascular damage rate [5.8%(3/52) vs. 25.5%(12/47), P<0.05]. There were no significant differences between these two groups in terms of intraoperative complications, CME, conversion rate, number of harvested lymph node, postoperative ileus, hospital stay, wound, lung and urinary system infections.

CONCLUSIONThe use of M-M approach in laparoscopic right hemicolectomy provides short-term benefits in operative time and estimated blood loss compared with traditional medial approach.

OBJECTIVETo explore the technical feasibility, safety, and clinical efficacy of β-shaped Roux-en-Y reconstruction(β reconstruction) in totally laparoscopic distal gastrectomy (TLDG).

METHODSClinical data of 21 patients with gastric cancer undergoing TLDG with β reconstruction from January 2014 to May 2014 were retrospectively analyzed.

RESULTSTLDG with β reconstruction was successfully performed in all the patients. The mean time of operation and β reconstruction was (229.0±18.7) min and (27.5±4.2) min. The blood loss was (91.0±38.3) ml and number of dissected lymph node was 33.2±4.6 per patient. The length of upper and lower segment of resection from lesion was (5.9±0.4) cm and (3.2±0.8) cm. The average time to resume fluid diet, time to restore flatus and hospital stay were (2.1±0.8) d, (3.1±0.9) d and (5.9±2.4) d, respectively.

CONCLUSIONThe β reconstruction is a safe and feasible procedure for TLDG and provides satisfactory short-term efficacy.

OBJECTIVETo explore the molecular mechanism for a boy suspected with 3-methylcrotonyl-CoA carboxylase deficiency by neonatal screening.

METHODSPCR and Sanger sequencing were used to identify potential mutations of MCCC1 and MCCC2 genes. SIFT and Polyphen-2 software was used to predict the effect of variant on the protein function and conservation of the variant across various species. Human Splicing Finder and Swiss-PdbViewer4.1.0 were applied to analyze the possible mechanism of the variant.

RESULTSFor the proband, a compound heterozygous mutation was discovered in the MCCC1 gene, namely c.539G>T (p.G180V) and c.704_711del (p.A235Vfs*4), which were inherited from his father and mother, respectively. The two mutations have disrupted the protein conformation, which in turn may impact the function of MCC protein.

CONCLUSIONThe compound heterozygous mutations of the MCCC1 gene may contribute to the 3-methylcrotonyl-CoA carboxylase deficiency manifested by the patient.

OBJECTIVETo compare the short-term efficacy between totally laparoscopic distal gastrectomy(TLDG) with delta-shaped anastomosis (DS) and laparoscopic-assisted distal gastrectomy (LADG) with BrillrothI ( anastomosis (BI(), and to evaluate the application of DS.

METHODSBetween March 2013 and February 2014, 50 patients underwent TLDG with DS using linear staplers, and 43 patients underwent LADG with BI( using circular staplers. Clinical features and short-term efficacy of the two groups were analyzed retrospectively.

RESULTSThere were no significant differences between the two groups in terms of demographic indicators, operation time, intraoperative blood loss, number of removal lymph node, time to first flatus, incidence of complication and postoperative discharge day(all P>0.05). First-day postoperative pain was milder (3.1 ± 1.0 vs. 4.6 ± 1.4), and operative incision was shorter [(3.4 ± 0.4) cm vs. (6.9 ± 0.8) cm] significantly in TLDG with DS group(P<0.05).

CONCLUSIONTLDG with DS is safe and feasible for patients with gastric cancer, and has more advantages in cosmetic and comfort level than LADG with BI.
