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.

Objective:To investigate associations of serum low-density lipoprotein cholesterol (LDL-C) with hematoma enlargement, early neurological deterioration (END), and outcome in patients with acute spontaneous intracerebral hemorrhage (ICH).Methods:"A multi-center registration study for spontaneous intracerebral hemorrhage in Inner Mongolia" (registration number: ChiCTR2000029494) database was used to include patients with ICH who completed their first head CT scan within 6 hours after onset, underwent blood lipid examination, CT follow-up within 24 hours of onset, and accurately measured hematoma volume using 3D Slicer software between June 2020 and September 2022. HE was defined as hematoma volume increasing >33% or >6 ml at 24 hours, or ventricular hematoma volume increasing ≥1 ml compared to the baseline. END was defined as an increase of ≥4 in the National Institutes of Health Stroke Scale (NIHSS) score from the baseline or death within 24 hours after onset. The follow-up was conducted at 3 months after onset, and the modified Rankin Scale score >2 was defined as poor outcome. Multivariate logistic analysis was used to determine the independent correlation between LDL-C and HE, END, and outcome. Results:A total of 338 patients with ICH were enrolled, including 206 males (60.9%). LDL-C was 2.39±1.22 mmol/L. Eighty-eight patients (26.0%) developed HE, 67 (19.8%) developed END, and 162 (47.9%) had poor outcome at 3 months. Multivariate logistic analysis showed that after adjusting for confounding factors, there was a significant independent negative correlation between LDL-C and HE (odds ratio 0.312, 95% confidence interval 0.208-0.467; P<0.001) and END (odds ratio 0.408, 95% confidence interval 0.275-0.606; P<0.001), but not with the outcome at 3 months. Conclusion:Lower LDL-C is associated with HE and END in patients with ICH, but not with the outcome.

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.

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 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.
