Chinese Journal of Minimally Invasive Surgery 2005;0(07):-
Objective To explore the efficacy of coblation nucleoplasty for the treatment of lumber disc herniation.Methods A total of 40 patients with lumber disc herniation were treated with coblation nucleoplasty in our hospital.Discogram was taken before the surgery.The patients with negative results were excluded from this series.Results The operation was completed in all the 40 cases(44 interspinous spaces).They were followed up for 2 to 8 months(mean 5 months).According to the Nakano's criteria,the outcome of the surgery was excellent in 8 and good in 29,accounting for 92%(37/40)of the patients.In the patients with central type lumber disc herniation,8(80%,8/10)had excellent or good outcome;whereas,in those with lateral type herniation,97%(29)of the 30 patients had such results.None of this series had complications.Conclusion Coblation nucleoplasty is a simple,safe,and effective surgery with minimal invasion for lumber disc herniation.

Objective To investigate the effect of rocuronium on spectral entropy during induction of general anesthesia in patients of Uygur nstionality. Methods Forty ASA Ⅰ or Ⅱ patients (Uygur nationality) of both sexes, aged 20-50 yr, weighing 45-70 kg, undergoing elective surgery under general anesthesia, were divided into 2 groups ( n = 20 each): normal saline (NS) group and rocuronium group (group R). Anesthesia was induced with target-controlled infusion of propofol. The initial target plasma concentration wan net at 2 μg/ml. The concentration wan then increased by 0.5 μg/ml every 4 min until response entropy (RE) was decreased to 45 and maintained for 4 min. When the plasma concentration was equal to the effect-site concentration, iv rocuronium 0.6 mg/kg was injected in group R, while group NS received the equal volume of NS instead. Fentanyl 3 μg/kg was injected intravenously at 3 min after recuronium administration. The patients were tracheal intubated and mechanically ventilated. State entropy (SE) and RE were recorded immediately before induction (baseline, To), before rocuronium administration (T1), 2 main after rocuronium administration (T2) and at 0, 1, 2 and 3 min after intubation (T3-6). The difference between RE and SE wan calculated. Results The RE value at T3 and T4 and the difference between RE and SE at T2.5 were significantly lower in group R than in group NS ( P < 0.05). Conclusion Rocuronium can decrease the RE value and degree of increase in the difference between RE and SE during induction of general anesthesia in patients of Uygur nationality, which may affect the accuracy of spectral entropy in monitoring the depth of anesthesia.

Objective:To observe the clinical effect of warm needling moxibustion plus Kai Qing Long Suo tuina therapy (opening the Qing Long lock,one type of'Eight and a Half Locks' tuina therapy) for cervical spondylosis of vertebral artery type (CSA).Methods:Sixty patients with CSA were randomly allocated into an observation group or a control group,with 30 cases in each group.The observation group was treated with warm needling moxibustion plus Kai Qing Long Suo tuina therapy,while the control group was treated with warm needling moxibustion alone.Warm needling moxibustion was conducted once every other day and tuina was conducted once a day,7-day treatments for one course.The clinical efficacy and vertebral artery blood flow was observed after one course of treatment.Results:After treatment,the total effective rate was 93.3% in the observation group versus 80.0% in the control group,and there was a significant difference between the two groups (P<0.05).After treatment,the systolic blood flow velocity of vertebral artery increased in both groups,with statistical significance compared with that before treatment (both P<0.05),and the blood flow velocity in the observation group was faster than that in the control group,with statistical significance between the two groups (P<0.05).Conclusion:Both warm needling moxibustion plus Kai Qing Long Suo tuina therapy and warm needling moxibustion alone are both effective for CSA,can improve the systolic blood flow velocity of vertebral artery.The curative effect of warm needling moxibusiton plus Kai Qing Long Suo tuina therapy is better than that of warm needling moxibustion alone.

BackgroundRetinitis pigmentosa (RP)is a group of progressive monogenic inheritance disease.Seldom epidemiology is performed to summarize the varied clinical phenotypes,especially some sporadic cases with untypical genetic history.ObjectiveThe aim of this survey was to investigate the clinical epidemiological characteristics and phenotype of sporadic RP.MethodsA prospective cohort study was designed.A survey of a series of clinically diagnosed sporadic primary RP patients was conducted at the Southwest Eye Hospital from July 2010 to November 2011.A total of 130 patients that matched the inclusion criteria were enrolled in this survey.Clinical ocular examinations and questionnaire surveys were given,including ophthalmoscopic examination,best corrective visual acuity( BCVA ),perimetry and Ganzfield electroretinogram (ERG)and color fundus photo.RP with different phenotypes were classified. ResultsA total of 130 sporadic RP patients were collected in this survey.Of them,66 were male and 64 were female with a mean age of (36.9±14.4) years.The average onset age of these subjects was (21.2±18.4) years.Seven (5.38%) patients had consanguineous marriage history,and 13 ( 10.00% )patients had systemic disease.Forty-four (33.85%) patients had outdoor jobs,and 86 (66.15% ) worked indoor.Eighty-nine patients had typical RP ( 68.5% ),and the number of patients that developed central RP and sine pigmento RP were 16 ( 12.3% ) and 16( 12.3% ),respectively.An absence of a- and b-waves in full-field ERG wasdetected in 99 (76.15% ) cases.The longest duration of night blindness was identified in typical RP patients and the lowest BCVA in central RP patients.ConclusionsThe age at first onset is early in sporadic RP.There are wide variations in different types of RP,but the ERG outcome is specific for all RP types.
