Objective To investigate influence of hyperlipidemia in parents on plasma lipid level,blood pressure,body mass index(BMI) and waist circumference(WC)of their children.Methods Eighty children whose parents had been with hyperlipidemia(Group A) and 893 children whose parents had been normal plasma lipid levels(Group B) were studied.BMI,systolic pressure(SP),diastolic pressure(DP),WC,plasma triglyceride(TG),cholesterol(CH),high density lipoprotein-cholesterol(HDL-c),low density lipoprotein-cholesterol(LDL-c)of two groups were measured and compared.Results The levels of BMI,TG,TCH,LDL-c,SP,and DP had a increasing trend in group A compared to those of group B.HDL-c in group A had a decreasing trend compared to that of group B.But only the increase of BMI is significant(P

20 was lower than those whose BMI≤20(P

0.05);IGF-I after therapy was higher than before(P

Objective To investigate the therapeutic effect of trans-TrkC gene neural stem cells (NSCs)on the recovery of neural function after spinal cord injury.Methods Sixty SD rats were ran- domly divided into six groups:normal control group(A),hemisection group(B),NSCs transplantation grnup(C),NSCs transplantation with the regional application of NT-3 group(D),trans-TrkC gene NSCs transplantation group(E)and trans-TrkC genc NSCs transplantation with the regional application of NT- 3 group(F),10 rats in each group.Nine days after the set up of animal models,cell transplantation into the injured spinal cord was performed.The BBB locomotor score was calculated,and MEP(motor evoked potential)and SEP(somatesensory evoked potential)were pedormed two months after cell transplanta- tion.Results Two months after cell transplantation,the BBB locomotor score was partly recovered, and the MEP and SEP(somatosensory evoked potential)results were also markedly improved in Group F, which indicated the restoration of the upward and downward nerve conduction function of the injured spinal cord.But it seemed that the restoration of the downward nerve conduction was better than that of the up- want,and the extent of the improvement of MEP and SEP results was larger than that of motion function recovery.The onset latency,peak to peak amplitude of MEP and SEP,and the BBB score of Group F re- stored the best compared with the other groups,and the differences were statistically significant(P

Objective To observe the curative effect of captopril and metoprolol in the treatment of chronic Keshan disease (CKD). Methods One hundred and ninty-five patients with CKD chosen from Juxian, Wulian, Yishui, Pingyi, Sishui and Zoucheng in Shandong Province were randomly assigned to control group, captopril group and metoprolol group according to NYHA cardiac functional grading. All cases were given diuretics, digitalis and vasodilating agents as routine treatment. On this basis, captopril and metoprolol was administered in captopril group and metoprolol group respectively. After 12 months of follow-up visit, the causes of cardiac death, hospitalization status and the changes of heart size, electrocardiogram, blood pressure and heart rate were all observed. Results It was found that the mortality of captopril group and metoprolo] group was 4.76% (3/63), 5.00% (3/60) respectively, both lower than the control group 10.61%(7/66). But this difference had no statistically significance(P=0.39). Besides, the hospitalization days of each year in captopril group and metoprolol group was respectively (19.12± 20.35) and(18.86±21.52)days, much more reduced than in the control group[(21.45±21.74)days, q=3.17, 3.38, P<0.05]. The detection rate of cardiothoracic ratio decreased in captopril group and metoprolol group [45% (27/60) and 40.4% (23/57)] After treatment showed more pronounced amelioration than the control group [18.6% (11/59), χ2=9.51,6.59, all P<0.0125], still the detection rate of cardiomegaly and invariability had no significant difference among three groups (χ2=2.50,4.75, all P>0.05). The elimination coefficient of ectopic rhythm in metoprolol group [56.5% (13/23)] was pronounced higher than the control group and captopril group [23.8% (5/21), 22.7% (5/22)], but differences had no statistically significance(P=0.0358,0.0331, all P>0.0125). Significant differences were found in systolic blood pressure(SBP), diastolic blood pressure(DBP) and heart rate(HR) in three groups prior and post-treatment(F=47.51,44.23,80.66, all P<0.01). The interaction of therapy and treatment time had influence on SBP and HR (F=3.19,37.44, all P<0.05), but had no influence on DBP(F=2.21, P> 0.05). There was no difference in SBP, DBP or HR among three groups before treatment(F=0.28,0.57,1.80, all P>0.05). After treatment, SBP and DBP in captopril group, metoprolol group and the control group[(109.0±10.9), (112.2±12.8), (114.7±13.2)mm Hg, (69.3±7.2), (72.1±9.5), (73.3±9.3)mm Hg] were all lowered compared with pre-treatment[ (117.1±13.4), (119.0±14.4), (117.6±14.1)mm Hg and (74.2±10.2), (76.3±10.8), (75.4±11.1)mm Hg, t=4.79,4.47,2.08,5.12, 4.32,2.15, all P<0.05]. HR was reduced in metoprolol group, being [(66.2±7.7), (75.9±11.5)times/min] before and after treatment(t=10.81, P<0.01), while it remained unchanged in captopril group and control group[(70.6±8.0), (72.6±10.5) times/min and (71.9±10.4), (73.8± 12.2)times/min, t=1.77,1.74, all P>0.05]. After treatment, both SBP and DBP of captopril group were significantly lower than that in the control group (q=3.52,3.56, all P<0.05); HR was reduced in metoprolol group, lower than that in captopril group and control group(q=5.44,3.73, all P<0.01). Conclusions Having a tendency of depressing mortality, captopril and metoprolol can reverse or delay myocardial remodeling and reduce admission rate in a safe,reliable and economic way, and are worth to be widely used in the treatment of chronic Keshan disease.

Objective To study the auditory perception and speech ability outcomes after cochlear implantation in prelingually deaf children with extremely severe neurosensory hearing loss and comorbid leukoencephalopathy.Methods Our study included 14 prelingually deaf children with leukoencephalopathy (confirmed by preoperative MRI scanning) who were treated with cochlear implantation in the Department of Otorhinolaryngology Head and Neck Surgery of Hainan Provincial People''s Hospital, including 8 males and 6 females of 1~6 yr with a mean age of 3.8 yr.Sixteen synchronous prelingually deaf children without central nervous system (CNS) diseases were also included as the control group, including 11 males and 5 females of 1~6 yr with a mean age of 4.4 yr.All the patients underwent pre-surgical assessments of audiology, radiology, speech ability and intelligence before cochlear implantation via transmastoid facial nerve recess approach was done, after which rehabilitation was provided at the Hainan Rehabilitation Center for Deaf Children.Categories of auditory performance (CAP) and speech intelligibility rate (SIR) were employed as the assessment criteria for the outcome of surgery, the scores of which at different timepoints after surgery were statistically compared through paired t-test between the two groups.Results All the patients gained post-surgical hearing and speech abilities to different degrees, whereas CAP and SIR scores both chronologically improved in the both groups.No statistical difference was revealed either in CAP or in SIR scores between the two groups at 6, 12 and 24 months after surgery (P>0.05).Conclusion Children with extremely severe neurosensory hearing loss can be reated with cochlear implantation even if they have comorbid leukoencephalopathy.The effects of auditory and speech rehabilitation for the same age patients with leukoencephalopathy are similar to those without leukoencephalopathy in 2 years after surgery.

Objective To evaluate the application and initial experience of laparoscopy in kidneypreserving surgery for savage giant hydronephrosis. Methods This series included 6 cases of savage gianthydronephrosis (2 men and 4 women;age range,15 -57 years;mean age,28 years).Of them 5 cases weredetected when visiting doctors due to flank pain,abdominal mass,and the rest one by B-ultrasound duringpregnancy.Four cases had hydronephrosis on the left;and 2 cases,on the right.The quantity of hydronephro-sis was 2250 -8300 ml,respectively.None had development on IVU examination.Of them,3 cases had con-genital ureteropelvic junction (UPJ) obstruction;2 had multiple stones in infracalices secondary to UPJ ob-struction;1 had stones in pelvis with polyp formation.Relieving obstruction,pyeloplasty,nephroplication andnephropexy were performed via laparoscope. Results All the operations were successful.The operativetime was 2.5 -5.0 h;the blood loss was 50 -150 ml,and the mean postoperative hospital stay was 7.2 d.The postoperative follow-up ranged from 3 to 24 months. Three months after operation,B-ultrasound showedthat giant hydronephrosis was markedly relieved in 5 cases (the renal sinus separation was 1.8 m,2.0 cm,2.5 cm,2.5 cm and 2.8cm,respectively),and in the rest 1 case the kidney was slightly smaller than nor-mal.IVU examination was performed every 3 months after operation, and different degrees of developmentappeared in all cases.During the follow-up,no obvious ureteropelvic anastomotic stricture was found on retro-grade pyelography (RGP). Conclusions The protective renal treatment via laparoscopy for savage gianthydronephrosis is a feasible and minimally invasive technique that provides the same clinical and radiograph-ic results as open operation.

OBJECTIVETo analysis the clinical presentation, radiological findings, surgical techniques and outcomes of jugular foramen (JF) schwannomas.

METHODSWe reviewed our 10-year experience in the surgical treatment of 17 patients suffered from JF schwannomas in Hua Shan Hospital, Shanghai. A total of 8 males and 9 females with a mean age of 42 years underwent surgical procedures. A relative long period of 53-month symptomatic history was shown before surgery. The main clinical presentation are vertigo and hearing difficulty in 10 cases, atrophy of unilateral muscles of tongue in 9 cases, involvement of lower cranial nerve in 8 cases. The classification of tumors was type A (at cerebellopontine angle with minimal enlargement of the JF) in five cases, type B (JF with intracranial extension) in 3 cases, type C (extracranial tumors with JF extension) in 2 cases and type D (dumbbell-shaped with both intra-and extracranial components) in 7 cases.

RESULTSFar lateral approaches were used in 10 cases, retrosigmoid suboccipital approaches were used in 5 cases. Submandibular approaches were selected in other 2 cases. Gross total removal was achieved in 12 cases, and subtotal removal in 5 cases. Follow-up revealed marked improvement from preoperative symptoms in 9 cases and no additional deficits in 3 cases. 5 cases suffered from additional neurological deficits. There were two cases of temporary hoarseness and gradually improved within follow-up. Two patients suffered from swallowing problems as a new deficit. One patient had facial palsy.

CONCLUSIONSJF schwannomas can be surgically treated with relative good outcomes. Surgical approaches should be tailored according to the tumor extension.
