A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the determination of butoconazole in human plasma. Human plasma samples of 0.2 μL were pretreated by a single step protein precipitation procedure and analyzed using a high performance liquid chromatography (HPLC) electrospray tandem mass spectrometer system. The compounds were eluted isocratically on an Inertsil ODS-SP column (100 mm×2.1 mm, 3 μm), ionized using a positive ion atmospheric pressure electrospray ionization source and analyzed using multiple reaction monitoring (MRM) mode. The ion transitions monitored were m/z 412.8→165.1 for butoconazole and m/z 453.4→230.3 for the internal standard. The chromatographic run time was 3.5 min per injection, with retention time of 2.47 min and 2.15 min for butoconazole and repaglinide, respectively. The method was validated to be linear over the range of 20 to 8000 pg/mL (r>0.999) by using a weighted (1/x(2)) quadratic regression. The mean recovery rate was more than 86.7%, and the intra- and inter-day precision of the quality control samples (QCs) was less than 8.3% and the accuracy ranged from 96.0% to 110.2%, which indicated that the quantitative method was reliable and accurate. The method is simple, rapid, and has been applied successfully to a pharmacokinetics study of butoconazole nitrate suppositories in healthy Chinese females.

OBJECTIVE: To observe the alteration of nestin intervals in the experimental traumatic brain injury and investigate its relation to the injury intervals. METHODS: The rat brain contusion was conducted by falling impact injury. After various survival interval (0.5, 6, 12 h and 1, 3, 7, 14, 28 d), immunohistochemical SP method was used for observing the expression of nestin in the cortex, hippocampal dentate gyrus and the corpus callosum on injury side. RESULTS: Expression of nestin positive cells increased at 0.5 h and reached the maximum level in 7 d after brain contusion, then the expression decreased gradually. The intensity of nestin staining in the the cortex and the hippocampal dentate gyrus decreased to normal on 28 d. As to the corpus callosum of injury side it remained weak on 28 d. CONCLUSION The changes of nestin immunohistochemical staining can be used as an index for forensic estimation of early injury time.

OBJECTIVETo evaluate the effects of autologous tumor vaccines in preventing recurrences of hepatocellular carcinoma (HCC).

METHODSFrom March 1999 to June 2003, 80 patients with HCC undergoing resections were randomly assigned into a tumor vaccine group (n=40) and a control group (n=40). Tumor vaccines, consisting of formalin-fixed HCC tissue fragments, biodegradable sustained-releasers of granulocyte-macrophage-colony stimulating factor, interleukin-2, and an adjuvant, were developed. Every vaccine group patient received 3 vaccinations at a 2-week interval and the control group just received the adjuvant. Delayed-type-hypersensitivity (DTH) test and recurrent rates were analyzed.

RESULTSEight patients of the vaccine group and five patients of the control group were lost in the follow-up. Thirty-two patients completed the tumor vaccine procedure and no essential adverse effects occurred. 23/32 patients developed DTH responses against the fragments of HCC. The follow-up averaged 34.3 months (from 15 to 55 months). 1-, 2-, 3-year recurrence rates of the vaccine group were 12.6%, 35.9% and 54.0%, respectively; 1-, 2-, 3-year recurrence rates of the control group were 31.6%, 61.3% and 72.1%, respectively. The recurrent rate was significantly better in the tumor vaccine group than in the control group (P = 0.037).

CONCLUSIONSAutologous tumor vaccine is a promising adjunctive modality to prevent recurrence of human HCC.

BACKGROUNDThe biofragmentable anastomosis ring (BAR) is a simple alternative device to create intestinal anastomosis. Our study was designed to evaluate the clinical value of BAR in intestinal anastomosis.

METHODSA total of 167 patients performed intestinal anastomosis from January 2002 to February 2006 were randomized to BAR group (n = 82) and manual suture group (n = 85) as control. They were equally allocated to the two groups regarding sex, age, site of anastomosis, emergent or elective surgery and contaminant diseases. The results of postoperative complications and recovery were recorded in each group.

RESULTSEighty-seven intraperitoneal BAR anastomoses were completed in 82 patients. Two and one postoperative deaths were recorded in BAR and suture group, respectively, no deaths were directly related to anastomotic technique. In suture group, anastomotic leakage and early bleeding both occurred in two patients respectively, no anastomotic bleeding occurred in BAR group, one patient in BAR group developed enterocutaneous fistulae. Perioperative bleeding, operation time and length of hospitalization were similar in two groups (P > 0.05). Time for return of bowel function was significantly shortened in BAR group than that in suture group (P < 0.05).

CONCLUSIONThe BAR appears to be a standard, easy, safe and effective alternative either in elective or emergent intraperitoneal intestinal anastomotic surgery.

BACKGROUNDMagnetic resonance imaging (MRI) is the most sensitive technique for evaluating the healing process and should be performed before the patients return to their exercise routines. The aim of this research was to diagnose chronic lumbago associated with lumbar muscle strain and to monitor healing process by MRI.

METHODSSixty-fve symptomatic cases of chronic lumbago caused by lumbar muscle strain were collected from March 2009 to October 2011. MRI was used to examine, diagnose and monitor the healing process. The control group included 65 random cases of asymptomatic volunteers. MRI methods included routine sequences of GRE T1WI, TSE T2WI and special sequences of T2-STIR-FS, combined with DWI. We compared the MRI characteristics of symptomatic cases before and after healing and with asymptomatic controls.

RESULTSThe important MRI characteristics of chronic lumbago with lumbar muscle strain included: (1) The low back muscle showed edema. (2) The low back intermuscular spaces showed edema and/or fluid. (3) The low back spaces beside the spinous process showed edema and/or fluid. (4) The low back vertebral articular process fossae or transverse process fossae showed fluid. Of these image characteristics, the intermuscular space edema provided the best diagnostic sensitivity, Se = 83%, with YI = 0.63, p = 74%. The low back muscle edema provided the best diagnostic specificity, Sp = 100%, with YI = 0.66, Π = 83%. And the spaces edema beside the spinous process provided the best diangnostic accuracy, Π = 86%, with YI = 0.71, Se = 80%, Sp = 91%. The diagnosis accurate could be improved by combining multiple MRI characteristics. The diagnostic accuracy could achieve Π = 93%, with YI = 0.86, Se = 100% and Sp = 86% when two characteristics were combined. After rehabilitation care, the edema disappeared on the repeated MRI.

CONCLUSIONSMRI may well be a useful diagnostic method for lumbago with lumbar muscle strain. Combining routine sequences with T2-STIR-FS and DWI sequences could demonstrate the pathological changes of lumbar muscle strain and monitor the healing.

Objective:To explore the clinical features, follow-up characteristics and prognosis of rheumatic disease complicated with pulmonary arterial hypertension (PAH) in children, and to provide support for its clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the data of rheumatic 24 patients complicated with PAH hospitalized in the Department of Rheumatology and Immunology, Children′s Hospital Affiliated to the Capital Institute of Pediatrics, Department of Rheumatology and Immunology, Jiangxi Children′s Hospital, Department of Pediatrics Ⅰ, the First Affiliated Hospital of Zhengzhou University and Department of Pediatrics, the Affiliated Hospital of Inner Mongolia Medical University from January 2013 to June 2022.The rheumatic patients complicated with PAH were followed up by telephone on June 30, 2022, and their clinical symptoms, treatment, follow-up, and prognosis data were collected.According to different treatment methods, the patients were divided into different clinical subgroups. The change of PAH was analyzed. The t-test was used for comparison between groups. P<0.05 was statistically significant. Results:A total of 24 cases were enrolled, with 7 males and 17 females.The average onset age of PAH was (10.97±3.79) years old.The median duration of PAH was 6.00 (32.20) months.The average pulmonary artery pressure was (51.71±17.66) mmHg(1 mmHg=0.133 kPa). There were 9 cases of systemic lupus erythematosus, 5 cases of Takayasu′s arteritis, 3 cases of juvenile dermatomyositis, 3 cases of undifferentiated connective tissue disease, 2 cases of systemic juvenile idiopathic arthritis, 1 case of Behcet′s disease, and 1 case of Kawasaki disease.Among 24 cases, the common symptoms were fever (14 cases), fatigue (10 cases) and dyspnea (7 cases). Of the 24 cases, 10 cases were complicated with hydropericardium, 9 cases with valve regurgitation, and 5 cases with decreased systolic and/or diastolic function.Lung changes were observed in 17 cases.Eleven cases were tested for B-type natriuretic peptide (BNP), and the BNP levels were all elevated in them (11 cases), with a median BNP of 3 073 (10 645) ng/L.After the first occurrence of PAH, 12 cases were treated with Methylprednisolone therapy, 10 cases received Cyclophosphamide therapy, and 2 cases who were both systemic lupus erythematosus, underwent blood purification.In the treatment of PAH, 11 cases were treated with pulmonary artery pressure reduction, and 7 of the 11 cases took PAH-targeted drugs.The mean decrease of the average pulmonary artery pressure in children receiving the targeted therapy[(44.80±24.08) mmHg] was significant higher than that in children not receiving the targeted therapy [(16.15±17.25) mmHg] ( t=2.661, P=0.016). Twenty children were reexamined and/or followed up, and the average course of PAH at the telephone follow-up was (36.29±26.67) months.The pulmonary arterial hypertension in 6 cases completely recovered, with median recovery time of 8.00 (13.47) months, but 2 of them died after the complete recovery.The pulmonary arterial hypertension improved in 11 children, 1 of whom died and the remaining children were in stable condition.The pulmonary arterial hypertension worsened in 2 children, 1 of them improved previously but aggravated recently, and the other child did not monitor pulmonary artery pressure and died during telephone follow-up. Conclusions:Rheumatic diseases complicated with PAH are rare and most often diagnosed in severe rheumatic children.It can lead to death, and is commonly accompanied by notably elevated BNP levels.The patients who have early PAH detection, intensive treatment of the primary disease, symptomatic and targeted pulmonary artery pressure reduction show a better prognosis.
