OBJECTIVETo compare two kinds of method for treating lumbar tuberculosis with psoas abscess, to provide reference for clinical reasonable select of therapy treatment.

METHODSFrom January 2010 to January 2013,42 patients with lumbar tuberculosis combined with psoas abscess with obvious surgical indications were enrolled, including 24 males and 18 females with an average age of (38.5 ± 10.2) years old ranging from 21 to 63 years old. All patients were followed up for 18 to 24 months with an average of 20.9 months. Twenty-two patients underwent posterior vertebral body lesions cleared, bone graft fusion and internal fixation and percutaneous puncture catheter drainage for treatment of psoas major abscess as group A, and twenty patients underwent one-stage extraperitoneal approach to remove abscess, posterior vertebral body lesions cleared, bone graft fusion and internal fixation as group B. The operative time, loss of blood, length of hospital stay, clinical cure rate and other clinical results for the two groups were analyzed and compared.

RESULTSThe loss of blood was (452.3 ± 137.6) ml in group A and (603.5 ± 99.6) ml in group B, there was significant statistical difference (P < 0.05). The time of operation was (193.6 ± 91.2) min in group A and (230.5 ± 56.6) min in group B, there was significant statistical difference (P < 0.05). The time of operation and the loss of blood in group A were obviously less than which in group B. In group A 20 cases were cured and 2 cases relapsed, 19 cases were cured and 1 case relapsed in group B, there was no significant statistical differences between two groups regarding cure rate with chi-square test (χ² = 0.000, P = 1.000). All patients in two groups obtained good clinical curative effect. There were no significant statistical difference between two groups regarding for length of hospital stay with t-test (P > 0.05).

CONCLUSIONLumbar spinal tuberculosis with psoas abscess is not absolute indications for anterior open operation. Compared with the combined anterior and posterior surgical procedure, the percutaneous puncture catheter drainage combined with posterior debridement, interbody fusion and internal fixation can achieve the same clinical effect but less trauma for the patients.

Objective Soft and hard channel minimally invasive interventions for patients with hypertensive intracerebral hemorrhage have been used for many years. A retrospective study was performed to evaluate the superiority of these two methods. Methods 122 patients with hypertensive intracerebral hemorrhage were included in this retrospective study, 64 cases in soft channel group and 58 cases in hard channel group. The clinical effects were compared; catheter retention time and complications of the minimally invasive surgery were also observed in these two groups. Results In soft channel group, NIHSS before the treatment was 18.05±7.77, and NIHSS after the treatment was 7.57±4.68. The mortality was 17.19%. The catheter retention time in hematoma puncture was (4.35±1.56)days, and the catheter retention time in ventricle puncture was (7.67±2.37)days. There were 4 cases of rebleeding and 3 cases of intracranial infection. In hard channel group, NIHSS before the treatment was 18.38±9.02, and NIHSS after the treatment was 8.02±4.84. The mortality was 20.69%. The catheter retention time in hematoma puncture was (4.07±1.49)days, and the catheter retention time in ventricle puncture was (8.17±2.55)days. There were 9 cases of rebleeding and 2 cases of intracranial infection. The differences were not statistically significant (P＞0.05). Conclusions Soft and hard channel minimally invasive interventions of hypertensive cerebral hemorrhage have the same clinical value.

Objective To explore the diagnosis and treatment of hypopara thyroidism-deafness-renal dysplasia(HDR) syndrome in children.Methods According to the symptoms,signs,laboratory examination and the previous published papers of other authors,the disease of the child was diagnosed and treated,and some related literatures were reviewed.Results The 12-years-old boy presented with tetany and deafness and Chvostek's and Trousseau's signs were positive.The initial laboratory studies showed that the serum concentration of calcium was lower,parathormone was in the low limit of normal range and alkalin phosphatase was normal.An audiography revealed the pattern of sensorineural deafness in all frequencies.Abdominal CT revealed that his right kidney was not observed and creatinine clearance rate was low.After treated with calcium carbonate and vitamin D,the symptoms and the signs were improved.Conclusion HDR syndrome is a rare disorder and less recognized in children,and therefore more attention should be paid to avoid missing diagnosis.

Background Ginkgolide B (GB) has been proved to have neuroprotective and anti-apoptotic effects and can effectively inhibit apoptosis of retinal photoreceptor cells.But the high hydrophobic feature and low bioavailability of GB limit its clinical application.Self microemulsifying drug delivery system (SMEDDS) can effectively improve the infusibility drug dissolution and bioavailability in the retina.Objective This study was to investigate the pharmacokinetics and drug-time change of GB-loaded SMEDDS in retina.Methods Eighty SD rats were randomized into 2 groups,2.5％ GB(40 mg/kg) of SMEDDS or GB suspension(0.1％ DMSO dissolve) were gastrically given respectively in two groups.The rats were sacrificed and retinas were isolated 15,30,45 minutes and 1 hour,2,4,8,12 hours to prepare the retinal suspension.The content of GB in retina was assayed with high performance liquid chromatography-electrospray ionization-(1) (1)ss spectrum (HPLC-ESI-MS) and contrasted with standard curve.Practical drug dynamics program 3p87 was used to detect the pharmacokinetics parameters.The maximal content(Cmax,mg/g),time to peak (Tmax,h),clearance ratio (Ke/h),high-life period (t1/2) and area under the concentration-time curve(AUC0-∞,mg/(g · h)) of GB in various time points in retina after a single oral dose were calculated and compared between two groups.Results The standard curve was obtained over the concentration range of 1-32 mg/L with a linear regression equation,Y =0.0732X + 0.056 (r =0.992).A similar content-time curve was seen between GB suspension group and GB-SMEDDS group.The GB content was higher in GB-SMEDDS group than that in GB suspension group from 30 minutes through 12 hours after administration of drugs.The Cmax of GB-SMEDDS group and GB suspension group were(15.83±1.84) mg/g and(2.65±0.10) mg/g,the AUC0-∞ were(15.30±0.11)mg/(g· h)and(6.42±0.19)mg/(g · h).Conclusions HPLC-ESI-MS is proved to be a rapid,accurate,sensitive and suitable method for pharmocokinetic study of GB.SMEDDS can raise the concent of GB in retina,and it probably improve the bioavailability of GB.
