Objective To discuss the experiences in successful treatment of hyperacute traumatic intracranial hematoma with percutaneous puncture and craniotomy.Methods Pereutaneous puncture and craniotomy was performed in 12 patients with hyperacute traumatic intracranial hematomas including seven with subdural hematoma,three with epidural hematoma and two with episubdural hematoma.Before operation,there found enlargement of bilateral pupil in six patients,enlargement of unilateral pupil in six and changed breathing rhythmicity in eight.Glasgow Coma Scale(GCS)was 3 points in four patients,4 points in six and 7 points in two.Results After pereutaneous puncture,enlarged pupil was retracted at different degrees in nine patients and spontaneous breathing conditions improved in seven.After crani otomy,two patients died within 24 hours,four died after 24 hours but six patients survived.The follow-up for 0.5-2 years showed four patients with sound Glasgow Outcome Score,two at vegetative state and six deaths.Conclusion Percutaneous puncture combined with craniotomy is an effective way for hyperacute intracranial hematoma.

Objective:To invetigate the value of a novel puncture and drainage of intracranial hematoma for the treatment of hypertensive intracerebral hemorrhage.Methods:In the group there were 27 patients with hypertensive intracerebral hemorrhage,with mean age of 61 years. Their hematomas located in thalamus(1 patient),basal ganglia(22 patients),and lobe(4 patients).The mean(SD)hematoma volume was 40(3.2)mL,the mean Glasgow Coma Scale (GCS)score was 10.15,and the mean National Institutes of Health Stroke Scale(NIHSS)score was 30.65 at admission.CT scan provided hematoma location.and the percutaneous puncture. grind and drainage were performed under the local anesthesia by using a novel puncture and drainage of intracranial hematoma.Results:No adverse events occurred during the punctures and after the procedures.One patiems died 20 days after procedure.Other patients were followed up for more than 6 months.Eight patients had a good outcome as assessed by Glasgow Outcome Scale(GOS)scores,15 had mild disability,2 had serious disability,and 1 was in a permanent vegetative state.Conclusions:This novel puncture and drainage of intracranial hematoma can be used in the treatment of hypertensive intracerebral hemorrhage,and it is simple and safe.

Objective To summarize our experience in prevention and treatment of stricture after esopageal burns in the past thirty years.Methods There were 168 cases in this series.Of them,158 cases underwent surgical management in this study.Modified intraluminal stenting was used in 34 cases, colon interposition without resection of strictured esophagus in 77 cases,gastric transposion with resection of the stricture in 27,repair of cervical stricture with platysma myocutaneous flap in 22,and miscellane- ous operation in 12.Eleven cases experienced operation twice or more at our department.Results Twenty-nine cases recovered after treatment with intraluminal stenting,and 5 re-experienced stricture after stent removal.One of the 5 cases with failed stent responded to bougienage,and the remaining 4 cases re- quired esophageal reconstruction later.Of the 77 colon interpositions,5 cases died postoperatively,and complications of cervical anastomotic fistula occurred in 14 cases,anastomotic stenosis in 4,and abdomi- nal incision dehiscence in 2 cases.In the 27 cases with gastric transpositions,postoperative complications of anastomotic stricture occurred in 2 cases and empyema in 1 patient.There was a cervical leak in 3 ca- ses of the 22 cases treated with the repair of cervical esopageal or anastomotic stricture with a platysma myocutaneous flap.In the 12 cases treated with miscellaneous operation,one died of intestinal obstruc- tion.All the survivors had regular diet after discharge.Conclusions Intraluminal stenting can prevent the formation of caustic esophageal stricture.The location of the cicatricial esophagus dictates whether to perform concomitant esophagectomy during esophageal reconstruction.Platysma myocutaneous flap repair is an excellent method for the treatment of severe cervical esophageal or anastomotic stricture.

AIM:To investigate the effect of vitrectomy in treatment of metal intraocular foreign bodies and the factors affecting visual prognosis.
METHODS:Fourty seven cases ( 48 eyes ) with foreign bodies from January 2010 to June 2013 in our hospital underwent vitrectomy combined with intraocular foreign body removal were retrospectively analyzed. The changes of visual acuity, the size of foreign body, the complications of preoperative, and the relationship between treatment time and visual acuity were recorded.RESULTS: Totally 46 eyes were successfully removed the complete foreign body, 2 eyes of orbital foreign bodies had not been removed. After 6mo of followed-up, the best corrected visual acuity were all improved in varying degrees (P<0. 05), intraocular foreign body size combined with retinal detachment was the risk factor for visual impact (P<0. 05).
CONCLUSION:Vitrectomy has obvious advantages in the treatment of metal intraocular foreign bodies. Timely and appropriate vitrectomy is very important to the recovery of visual function.

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.

METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).

RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.

CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

OBJECTIVETo investigate the effectiveness of (131)I-epidermal growth factor (EGF) on the proliferation of a heterologous graft in nude mice bearing human breast infiltrating duct carcinoma.

METHODSEGF/HAS was labeled with (131)I by chloramines-T method. Human breast cancer xenografts with positive EGFR expression were established in nude mice. The nude mice were injected with normal saline, Epirubicin Hydrochloride, (131)I-EGF, (131)I-HAS, (131)I intravenously and (131)I-EGF intratumoral administration respectively. The tumor growth inhibition rate was determined by measurement of tumor volume. Different examinations were carried out.

RESULTSThere was remarkable significant difference of tumor volumes at 26th day among (131)I-EGF trial groups, (131)I, (131)I-HAS, and the negative control group. The tumor growth inhibition rate of (131)I-EGF trial groups was 82.0%, 80.7% respectively. Compared with the negative control group, the (131)I-EGF trial groups remarkably suppressed the growth of tumor (P < 0.05). Irreversible destruction of tissues in (131)I-EGF groups was observed under light and electron microscope. There was no evidence of hepatotoxicity, renal toxicity and myelotoxicity in nude mice bearing human breast cancer given (131)I-EGF over a 4-wk observation period.

CONCLUSION(131)I-EGF has obvious antitumor effects on a heterologous graft in nude mice bearing human breast infiltrating duct carcinoma, with little obvious side effects.

In this study, the expressions of growth hormone secretagogue receptor type 1a (GHS-R1a) in the rat dorsal root ganglion (DRG) and nodose ganglion (NG) were investigated by using immunohistochemistry and in situ hybridization. The results clearly showed the presence of GHS-R1a mRNA and GHS-R1a-positive neurons in the rat DRG and NG. GHS-R1a was also co-localized with calcitonin gene-related peptide (CGRP) in some DRG and NG neurons, indicating the existence of subpopulations of the visceral afferents. The extrinsic primary afferent visceroceptive DRG and NG neurons from the stomach were identified by retrograde tracing fluorogold and stained for GHS-R1a and CGRP. Some neurons both positive for CGRP and GHS-Rla were labled by fluorogold. Our results not only demonstrate the expression of GHS-R1a in the vagal afferents but also provide the first and direct morphological evidence for its presence in the spinal visceral afferents, and gherin might have a modulatory role in the visceral afferent signaling.
