OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.

OBJECTIVETo evaluate the clinical effects of dynamic neutralization system (K-Rod) in treating multisegmental lumbar degenerative disease.

METHODSFrom October 2011 to October 2013, 20 patients with multisegmental lumbar degenerative disease were treated with dynamic neutralization system (K-Rod). There were 8 males and 12 females with an average age of 45.4 years old (ranged from 31 to 65) and an average course of 3.8 years (ranged from 9 months to 6.25 years). All patients had the history of low back and legs pain. Among them, 10 cases were far lateral lumbar disc herniation, 7 cases were lumbar spinal stenosis, 3 cases were lumbar spondylolisthesis (degree I in 2 cases and degree II in 1 case). Every patient had only one responsible segment which causing the symptom would have to be rigidly fixed during operations, and the adjacent intervertebral disc of the responsible segments at least 1 segment has already obvious degenerated. All patients underwent the operation to relieve compressed nerves and reconstruct spinal stability with K-Rod system (the responsible segments were fixed with interbody fusion, and the adjacent segments were fixed with dynamic stabilization). Visual analogue scale (VAS), Japanese Orthopaedic Association Scores (JOA) and Oswestry Disability Index (ODI) were used to evaluate the clinical effects. Imaging data were used to analyze the range of motion (ROM), intervertebral disc height and intervertebral disc signal (according to modified Pfirrmann grading system) in degenerative adjacent segment.

RESULTSAll patients were followed up for more than 1 year, and preoperative symptoms obviously relieved. There were significant differences in VAS, JOA, ODI between preoperative and postoperative (postoperative at 1 week and 1 year) (P<0.05). Radiological examination showed that all responsible segments had already fused, and no looseness, displacement and breakage of internal fixations were found. Postoperative at 1 year, the ROM of adjacent segments were decreased (P<0.05). There was no significant difference in intervertebral disc height between preoperative and postoperative at 1 year (P>0.05). According to modified Pfirrmann grading system to classification for the 25 disks of adjacent segment, 8 disks (32%) got improvement, 15 disks (60%) got no change and 2 disks (8%) got aggravation at 1 year after operation.

CONCLUSIONDynamic neutralization system (K-Rod) combined with interbody fusion could obtain short-term clinical effects in the treatment of multisegmental lumbar degenerative disease.

BACKGROUNDAlthough video-assisted radical operation for lung cancer has been widely accepted for treatment of nonsmall cell lung cancer (NSCLC), the debate over video-assisted thoracic surgery (VATS) segmentectomy still remains. This study analyzed the clinical outcomes using VATS segmentectomy for stage I NSCLC patients to explore the safety and efficacy of VATS segmentectomy for Ia NSCLC.

METHODSRetrospective review was conducted of patients who underwent VATS segmentectomy for clinical stage I NSCLC at Shanghai Chest Hospital between November 2009 and May 2012. VATS segmentectomy was performed on 36 patients. Analyses of the patient group were performed on patient demographics and clinical characteristics, intraoperative parameters, complications, and postoperative survival.

RESULTSThirty-five of thirty-six patients underwent VATS segmentectomy with only one conversion to open thoracic surgery. There was one peri-operative mortality from the segmentectomy group and all other patients are alive with a median follow up of 327 days. The mean volume of chest tube drainage after operation for segmentectomy was 1021.4 ml. Among other parameters, the mean blood loss was 162.5 ml (50.0 - 1600.0 ml), the mean operation time 124.8 minutes (75.0 - 271.0 minutes), chest tube duration 4.1 days (2 - 8 days), and the mean length of hospital stay 6.2 days (4 - 11 days). There was one (2.8%) locoregional recurrence after segmentectomy. Two patients successfully underwent bilateral segmentectomies and are still disease free.

CONCLUSIONFor patients with stage I NSCLC, VATS segmentectomy offers a safe and equally effective option and can be applied to complicated operations such as bilateral segmentectomy.

OBJECTIVETo explore the relationship between Fas-FasL-mediated signal transduction pathway and apoptosis of T lymphocyte subset in ITP patients.

METHODSThe expression rates of membrane Fas, FasL and intracellular activated caspase-3 in peripheral T lymphocyte subset were determined by flow cytometry. T cell subsets with caspase-3 protein expression were detected by Western blot.

RESULTSAs compared with that in healthy control group [(29.4 +/- 8.2)%], the expression rate of membrane Fas on CD4+ T cells was significantly increased in ITP patients [(42.1 +/- 9.5)%] (P < 0.05), however, that on CD8+ T cells was only slightly increased [(9.3 +/- 6.0)% vs (13.4 +/- 5.8)%] with no statistical significance (P > 0.05). The expression rate of FasL on T cell subset in ITP patients was significantly increased (P < 0.05), and that of intracellular activated caspase-3 in T cell subset in ITP patients was notably higher than that in healthy control group (P < 0.05). Western blot analysis showed that the expression of pro-caspase-3 and cleaved-caspase-3 in CD4+ T cells in patients with ITP after treatment were significantly reduced compared with those before treatment (P < 0.05).

CONCLUSIONApoptosis of T lymphocyte subset in ITP patients is accelerated. It is possible that Fas-FasL signal transduction pathway plays an important role in the induction of the apoptosis. The degree of apoptosis of T lymphocytes closely correlates with the disease's activity in ITP patients. Hormone therapy may interfere with Fas-FasL signal transduction pathway of apoptosis.

Objective To measure the concentration of intracellular free Ca2+ ([Ca2+]i) in neuron-like cells resulted from rat bone mesenchymal stem cell (BMSCs) differentiation induced by salvia miltiorrhiza injection and provide some theoretical basis for the BMSCs transplantation. Methods The rat BMSCs were separated from rat bone marrow and cultured in vitro. After induced by basic fibroblast growth factor and 10mL/L salvia miltiorrhiza injection, the cells were identified with immunofluorescence staining against NeuN. The same procedure was performed on primarily cultured hippocampal neurons. Then, the [Ca2+]i of the differentiated neuron-like cells was determined and compared with primarily cultured hippocampal neurons. Results The BMSCs after induced by basic fibroblast growth factor and salvia miltiorrhiza injection expressed neuronal phenotypes similar to the cell appearance of neurons with NeuN. The average fluorescence intensity of the neuron-like cells derived from BMSCs was 984.75±79.51, while the average fluorescence intensity of the primarily cultured hippocampal neurons was 769.42±60.93. No significant difference was found between them (P>0.05). Conclusion The neuron-like cells from rat BMSCs differentiation induced by salvia miltiorrhiza injection possess certain neuronal properties.

OBJECTIVETo identify the RUNX2 gene mutation in two unrelated Chinese families with cleidocranial dysplasia (CCD), and to assess the feasibility of gene diagnosis for patients with CCD.

METHODSGenomic DNA was isolated from peripheral blood samples of 4 patients and 4 healthy members in the two pedigrees as well as 102 unrelated healthy controls. All 7 coding exons and their flanking intronic sequences of the RUNX2 gene were amplified by PCR, then the PCR products were sequenced bi-directionally. The sequencing results were compared with normal sequences in GenBank to identify the mutation. The mutation was confirmed by RFLP with restriction endonuclease.

RESULTSIn one family, a novel heterozygous missense mutation c.346T to A (W116R) in exon 1 of the RUNX2 gene was detected in the two affected individuals, and the mutation was further confirmed with Bsr I restriction endonuclease digestion. In the other family, a novel nonsense mutation c.610A TO T (K204X) was identified in the two patients. No above sequence change was found in the 102 healthy controls.

CONCLUSIONTwo novel RUNX2 mutations were found in two unrelated Chinese families with cleidocranial dysplasia. The identification of these mutations further extended the mutation spectrum of RUNX2 gene and will facilitate prenatal diagnosis and gene diagnosis of CCD.

OBJECTIVETo study the changes in serum cortisol levels in adolescents with type 1 diabetes (T1DM) and elevated depressive symptoms.

METHODSTwenty-eight adolescents with T1DM and 31 healthy peers were assessed for depressive symptoms using a depression self-rating scale developed by the Epidemiological Survey Center. Selected subjects were classified into four groups: T1DM with elevated depressive symptoms group (n=15), T1DM without elevated depressive symptoms group (n=13), elevated depressive symptoms without T1DM group (n=15), and normal control group (n=16). Fasting blood samples were collected in the morning, and the levels of serum cortisol were compared among the four groups. The correlations of serum levels of cortisol and glycosylated hemoglobin A1c (HbA1c) with the score of depression self-rating scale were evaluated by Pearson correlation analysis.

RESULTSThe fasting serum cortisol levels in the 28 T1DM patients were significantly higher than in the 31 healthy peers (P<0.01). The fasting cortisol levels in the T1DM with elevated depressive symptoms group were significantly higher compared with those in the elevated depressive symptoms without T1DM group and normal control group (P<0.01). In adolescents with T1DM, serum HbA1c level was positively correlated with the score of depression self-rating scale (r=0.481, P=0.010).

CONCLUSIONSThe fasting serum cortisol levels in adolescents with T1DM and elevated depressive symptoms are significantly increased, suggesting that the patients with comorbidity of T1DM and depression develop dysfunction of the corticotropin-releasing hormone-adrenocorticotropic hormone-cortisol axis. The elevated depressive symptoms may be associated with a poor control of glucose metabolism.
