OBJECTIVETo investigate the relationships between erythrocyte membrane n-6:n-3 PUFAs ratio and blood lipids and high sensitivity C-reactive protein (hs-CRP).
METHODSThe observational study consisted of a population-based cross-sectional study of 456 Chinese and a subsequent 1-year follow-up study of 171 subjects with the fasting plasma total cholesterol of 5.13-8.00 mmol/L.
RESULTSIn the cross-sectional analysis, plasma low-density lipoprotein cholesterol (LDL-c) had a significant and negative association with the erythrocyte membrane n-6:n-3 PUFAs ratio (P for trend=0.019) after adjusting for sex, age and total PUFA percentage. In the follow-up study, 171 subjects were categorized into quartiles by the changes of n-6:n-3 ratio in erythrocyte membrane (Δ=month 12-month 0). In the top quartile whose ratios of n-6:n-3 increased by an average of 1.25 during the follow-up, the LDL-c-lowering extent was 3.3 times of that in the lowest quartile whose ratios of n-6:n-3 decreased by an average of 1.13 (-1.07 mmol/L v.s. -0.32 mmol/L). The hsCRP decreased by 0.11 mg/dL in the lowest quartile while increasing by 0.10 mg/dL in the top quartile (P for difference=0.052).
CONCLUSIONOur results suggested that the balance between n-6 and n-3 fatty acids may optimize the cardiovascular benefits from dietary PUFAs.

OBJECTIVE:
To investigate the intra-operative electrical evoked auditory brain stem response (EABR) characteristics and the hearing and speech rehabilitation effects of cochlear implantation (CI) in patients with internal auditory canal stenosis (IACS).
METHOD:
A retrospective study was performed on 16 patients with IACS (IACS group) matched with 16 implanted without IACS (control group), who received multi- channel CI because of pre-lingual sensorineural hearing loss. The integrity and functional status of the auditory pathway were assessed by EABR, recording waveforms, thresholds and dynamic ranges intra-operation before CI. Interviewed the implanted parents or teachers, asking them to rate the implanted hearing and speech ability according to Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR). Paired T test was performed to compare scores of CAP and SIR between before and 1 year after CI, while Spearman test was performed to compare correlation between EABR grades and post-operative CAP scores.
RESULT:
Among the IACS group, 2 cases weren't recorded typical EABR waveforms and without auditory response 1 year after a successful CI. The EABR waveforms in the IACS group were poorer than that in the control group, their EABR thresholds higher than the control group, and their EABR dynamic ranges less than the control group. The hearing and speech rehabilitation after CI showed that the results of CAP and SIR values (3.47 +/- 1.09 and 1.62 +/- 0.50) scored significantly lower than the control group (5.06 +/- 0.79 and 2.59 +/- 0.58) (P < 0.05), but significantly increased compared with pre-operation. Intra-operative EABR grades and post-operative CAP scores showed significant correlation (r = 0.78 , P < 0.05).
CONCLUSION
Intra-operative EABR can accurately monitor the integrity and functional status of the auditory pathway, be of important clinical value in predicting whether patients can acquire auditory responses with the aid of CI. CI can help patients with IACS to improve the ability of hearing and speech with EABR to screen out compatible implanted.

OBJECTIVE:
To evaluate the pathological position of auditory neuropathy and investigate the hearing and speech rehabilitation results of cochlear implantation in patients with auditory neuropathy.
METHOD:
In our hospital, among the patients received cochlear implantation, 8 cases with auditory neuropathy were selected, and 8 cases of non-auditory neuropathy patients with profound deafness were selected as matched control group with the background close to the study group. The preoperative hearing data of these two groups were retrospectively analyzed. During operation, the homemade stimulation electrodes were inserted to test the electric evoked auditory brainstem response(EABR) for assessing the auditory pathway; EABR and neural response telemetry(NRT) were tested after implantation, and T, C value were acquired 1 month later. CAP, SIR and speech recognition rate were used to assess hearing and speech rehabilitation effect 12 months after booting.
RESULT:
Intra-operative EABR wave can be derived in 8 cases of auditory neuropathy, but the wave pattern exhibited variations compared with normal wave. It needed increased stimulation or adjusted parameters, with variable V latency. After cochlear implantation, the waveforms of NRT and EABR were similar between the two groups, and the post-operative V waveform was close to the intra-operative EABR. 8 pairs of patients can present listening response after booting. There was no statistically significant difference in T, C value, CAP (6.50 +/- 0.94 and 6.90 +/- 0.77) and speech recognition rate (85.00% +/- 11.66% and 89.50% +/- 9.02%) between the auditory neuropathy group and the control group 1 year after booting.
CONCLUSION
Pre-operative EABR can be used as an effective tool to assess the auditory pathway of auditory neuropathy patients, improving the pre-operative examination and helping with selecting the suitable cochlear implant patient. Cochlear implantation can help patients with auditory neuropathy to improve hearing and speech.

OBJECTIVE:
To investigate the hearing and speech rehabilitation results of cochlear implantation in patients with common cavity deformity.
METHOD:
A retrospective study was performed on 19 patients with common cavity deformity who received multi-channel cochlear implantation from 1995 to 2010 in Peking Union Hospital, with assisted evaluation of auditory nerve pathways by intraoperative electrical evoked auditory brain stem response (EABR); matched with 19 implantees with no deformity. Paired T test was performed to compare T values, dynamic range; Rank-sum test was performed to compare scores of categories of auditory performance (CAP) and speech intelligibility rating (SIR).
RESULT:
The T value of common cavity inner ear malformation group (172.59 +/- 14.57) was significantly higher than that of the control group (139.63 +/- 19.45) (P < 0.05), no significant difference in dynamic range (P > 0.05); hearing and speech rehabilitation after implantation showed that the results of CAP and SIR values (5.50 +/- 0.94 and 3.00 +/- 0.82) scored significantly lower than the control group (6.90 +/- 0.77 and 3.90 +/- 0. 57) (P < 0.05), but significantly increased compared with that before. Some children appeared facial twitch at boot time caused by electrical stimulation of the facial nerve (surface pumping rate of 31.58%).
CONCLUSION
Common cavity is a kind of severe inner ear malformations, but to perform a comprehensive preoperative evaluation, select the appropriate surgical technique, employ personalized postoperative booting, transfer machines and long-term auditory intensive language training, the children can get varying degrees of language and hearing recovery according to the severity of deformity. On the whole, the rehabilitation outcome was significantly worse in patient with deformity than its counterpart without deformity.

Objective:To evaluate the application of enhanced recovery after surgery in patients undergoing laparoscopic gastric cancer surgery and its impact on the systemic inflammatory response (SIR).Methods:The clinical data of patients undergoing laparoscopic gastric cancer surgery at the Department of Gastrointestinal Surgery, Zhongnan Hospital, Wuhan University from Mar 2021 to Mar 2023 was retrospectively analyzed.Results:A total of 234 patients with gastric cancer were enrolled (120 cases in ERAS group and 114 cases in routine group). There were no significant differences in preoperative indexes between the two groups (all P>0.05). After laparoscopic surgery, the postoperative ventilation time and hospital stay of patients in ERAS group were significantly shorter than those in the conventional group (all P<0.05). Neutrophil to lymphocyte ratio (NLR) , platelet to lymphocyte ratio (PLR) and systemic immune-inflammatory (SII) index of patients in ERAS group were significantly lower on day 1 and day 3 after surgery than in conventional group (all P<0.05). The ratio of lymphocyte to monocyte (LMR) in ERAS group was significantly higher than that in conventional group on day 1 and day 7 after surgery (all P<0.05). Conclusions:ERAS can improve postoperative SIR indexes in patients undergoing laparoscopic gastric cancer surgery, shorten postoperative recovery time, and enhance the efficacy of laparoscopic gastric cancer surgery by reducing perioperative systemic inflammation.
