BACKGROUND: Glutamine (Gln) supplementation is known to decrease oxidative stress and inflammatory response, enhance resistance to infectious pathogens, shorten hospital stay, and decrease medical costs of patients. This study was undertaken to evaluate the relationship between the effect of early parenteral glutamine (Gln) supplement on acute liver injury (ALI) and heat shock protein 70 (HSP-70) expression in critical patients. METHODS: Forty-four patients who had been admitted to the emergency intensive care unit (EICU) of Nanjing First Hospital Affiliated to Nanjing Medical University were randomly divided into a control group (n=22) and a Gln group (n=22). The patients of the two groups received enteral and parenteral nutrition. In addition, parenteral Gln 0.4 g/kg per day was given for 7 days in the Gln group. Serum HSP-70 and Gln were measured at admission and at 7 days after admission. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBiL), serum levels of HSP-70 and Gln, mechanical ventilation (MV) time, ICU stay, peripheral blood of TNF-α, IL-6, CD3, CD4 and CD4/CD8 levels were also measured in the two groups. RESULTS: In the Gln group, the levels of serum HSP-70 and Gln were significantly higher after Gln treatment than those before the treatment (P<0.01). HSP-70 level was positively correlated with the Gln level in the Gln group after administration of parenteral Gln (P<0.01). The levels of serum ALT, AST, TBiL and TNF-α, IL-6 were lower in the Gln group than in the non-Gln group (P<0.01). MV time and ICU stay were significantly different between the two groups (P<0.05). The levels of CD3, CD4 and CD4/CD8 were significantly higher in the Gln group than in the control group after treatment (P<0.05). CONCLUSION: Parenteral Gln significantly increases the level of serum HSP70 in critically ill patients. The enhanced expression of HSP70 is correlated with improved outcomes of Gln-treated patients with acute liver injury.

OBJECTIVETo explore the operation methods and clinical effects of transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament in treating complete acromioclavicular joint dislocation.

METHODSFrom January 2006 to June 2012,26 patients with acute complete acromioclavicular joint dislocation underwent surgery. Transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional clavical hoot plate and Kirschner wires fixation, were performed in all the patients. Among the patients, 18 patients were male and 8 patients were female, with an average age of 36.7 years old (ranged from 25 to 51 years). The duration from injury to operation was from 3 to 12 days with an average of 5 days. According to the Rockwood classification, 4 cases were grade III and 22 cases were grade V . Clinical manifestation included local swelling, tenderness with snapping, limitation of shoulder joint motion. In preoperative bilateral shoulder joint X-rays, the injured coracoclavicular distance was (16.2 ± 5.0) mm which was significantly wider than that of uninjured sides (7.6 ± 1.0) mm. Clinical results were evaluated according to X-rays and Constant-Murley score.

RESULTSAll incisions obtained primary healing after operation without complication of infection, internal fixation breakage, redislocation. All the patients were followed up from 12 to 30 months with an average of 18 months. Kirschner wires and internal fixation plate were removed at 1 month and 8-10 months after operation, respectively. At final follow-up, the motion of shoulder joint recovered to normal and a no pain joint was obtained. According to Constant-Murley score, 24 cases got excellent results and 2 cases good. There was no significant difference after operation between the injured coracoclavicular distance and the uninjured contralateral side [(7.7 ± 1.2) mm vs (7.6 ± 1.0) mm), P > 0.05].

CONCLUSIONTransfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional fixation using hook plate and Kirschner wires is the effective surgical method in treating complete acute acromioclavicular joint dislocation.

Objective To evaluate the effect of combination of autologous fascia and fat injection into vocal fold for the treatment of patients with unilateral vocal fold paralysis and to observe the long-term effectiveness of this procedure. Methods A total of 26 unilateral vocal fold paralysis patients underwent vocal fold injection under general anesthesia, meanwhile, the mucosa of the injected point was sutured through laryngoscope under direct vision. There were 6 patients underwent autologous fat injection into vocal fold ( group A), and 20 patients underwent autologous anterior rectus sheath fascia and fat injection ( group B). Therapeutic efficacy were evaluated by videostroboscopy, voice-related parameters analysis and voice evaluation before and after treatment. Clinical analysis of this procedure was retrospectively performed in this serial of patients. Results All patients were followed up for 24 months. On the third day after operation,there was an acute inflammatory reaction induced by the graft. This reaction disappeared three months later.In all 20 eases, videolaryngostroboscopy showed significant improvement of the glottic closure, the improvement in acoustical parameters was statistically significant ( P ＜ 0. 01 ). Perceptual evaluation of GRBAS scale showed significant improvement of phonatory function on G, B, A scale. The results remained stable 6 -24 months after operation and were not changed by the length of follow-up. And in the 6 cases,videolaryngostroboscopy showed significant improvement of the glottic closure at 3 months compared with preoperative observation, a little spindle-shaped disclosure. The improvement in acoustical parameters was significant statistically at 3, 6 and 24 months (P ＜ 0. 05 or ＜ 0. 01 ), the voice quality decreased significantly at 6 and 24 months compared with 3 months (P ＜0. 05 or ＜0. 0l ). The significant differences were not observed between 6 and 24 months (P ＞ 0. 05 ). No complications were observed in all patients perioperatively or during the follow-up period. Voice-related parameters jitter, normalized noise energy and maximum phonation time showed significant differences between Group A and Group B on 24 months ( P ＜0. 05 or ＜ 0. 01 ). Conclusion The combination of autologous fascia and fat vocal fold injection is an effective procedure for the treatment of unilateral vocal fold paralysis, and the stable results can be achieved during the follow-up period for 24 months.
