Effect of Chinese Herbal Medicine Jinlida Granule in Treatment of Patients with Impaired Glucose Tolerance / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Diabetes mellitus (DM) remains a major health problem worldwide. Several clinical trials have shown the superiority of the Traditional Chinese Medicine in delaying or reversing the development and progression of DM. This study aimed to evaluate the efficacy of Jinlida (JLD) granule, a Chinese herbal recipe, in the treatment of impaired glucose tolerance (IGT) and its effect on the prevention of DM.</p><p><b>METHODS</b>Sixty-five IGT patients were randomized to receive one bag of JLD granules three times daily (JLD group, n = 34) or no drug intervention (control group, n = 31) for 12 weeks. Oral glucose tolerance test, glycated hemoglobin A1c (HbA1c), body mass index, blood lipids levels, fasting insulin, and insulin resistance calculated using homeostatic model assessment (HOMA-IR) of all the patients were observed and compared before and after the treatment.</p><p><b>RESULTS</b>Sixty-one participants completed the trial (32 in JLD group and 29 in the control group). There were statistically significant decreases in HbA1c (P < 0.001), 2-h plasma glucose (P < 0.001), and HOMA-IR (P = 0.029) in JLD group compared with the control group after 12 weeks of treatment. After 12 weeks of treatment, two (6.9%) patients returned to normal blood glucose, and five (17.2%) patients turned into DM in control group, while in the JLD group, 14 (43.8%) returned to normal blood glucose and 2 (6.2%) turned into DM. There was a significant difference in the number of subjects who had normal glucose at the end of the study between two groups (P = 0.001).</p><p><b>CONCLUSIONS</b>JLD granule effectively improved glucose control, increased the conversion of IGT to normal glucose, and improved the insulin resistance in patients with IGT. This Chinese herbal medicine may have a clinical value for IGT.</p>

<p><b>OBJECTIVE</b>To retrospectivly compare the clinical efficacy of dynamic hip screw (DHS) with proximal femoral nail anti-rotation (PFNA) for the treatment of unstable intertrochanteric fractures in the elderly.</p><p><b>METHODS</b>Totally 92 elderly patients with unstable intertrochanteric fractures were treated with DHS [including 27 males and 23 females with a mean age of (72.5 +/- 5.3) years old] and PFNA [including 22 males and 20 females with a mean age of (72.8 +/- 5.8) years old] from August 2008 to August 2012. The data of operation time,blood loss (obvious and hidden blood loss), bedridden time, down load time, postoperative complications and Harris hip function score were recorded and compared.</p><p><b>RESULTS</b>Both of two groups were followed-up for 10 to 18 months with an average of 13.5 months. PFNA was implanted with a significantly smaller incision and shorter clinical healing time, less blood loss,while hidden blood loss were more. Postoperative complications, therapeutic effects and Harris score in PFNA group were better than that of DHS group.</p><p><b>CONCLUSION</b>For treatment of senile patients with unstable intertrochanteric fractures, PFNA was superior to DHS in reducing complication rates, recovering hip joint, while DHS could reduce perioperative blood loss in treating type II a, II b and III fracture.</p>

Serum peptidome profiling for identifying pathological patterns in patients with primary nephrotic syndrome / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Renal biopsy is necessary for diagnosing the pathological changes of primary nephrotic syndrome (NS). However, it is invasive, time-consuming and can not be performed frequent on the same patient. Thus, development of a non-invasive and rapid diagnostic method may improve clinical patient management.</p><p><b>METHODS</b>Proteomic tool magnetic bead-based matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MB-based MALDI TOF MS) was applied to serum to determine peptidome patterns that are characteristic of different pathological changes.</p><p><b>RESULTS</b>Serum specimen from 114 patients with NS (62 were minimal change disease (MCD), 30 were membranous nephropathy (MN), and 22 were focal segmental glomerulosclerosis (FSGS)) and 60 normal individuals were analyzed using MB-based MALDI TOF MS. The peptidome pattern was generated by genetic algorithms using a training set of 31 MCD, 15 MN, 11 FSGS and 30 normal individuals and was validated by an independent testing set of the remaining samples. The serum peptidome pattern, based on a panel of 14 peaks, accurately recognized samples from MCD, MN, FSGS and healthy control with sensitivities of 93.5%, 86.7%, 63.6% and 90.0%, and specificities of 98.2%, 94.4%, 100% and 89.5%, respectively. Moreover, one peptide from peptidome pattern was identified by liquid chromatography tandem mass spectrometry (LC MS/MS) as fibrinogen A.</p><p><b>CONCLUSION</b>Detection of the serum peptidome pattern is a rapid, non-invasive, high-throughout, and reproducible method for identifying the pathological patterns of patients with nephrotic syndrome.</p>

<p><b>OBJECTIVE</b>To study the effect of minimally invasive treatment with the locking compression plate (LCP) in the treatment of intertrochanteric fractures in the elderly age.</p><p><b>METHODS</b>Twenty-eight cases of intertrochanteric fracture were retrospective studied from August 2007 to January 2009, included 13 males and 15 females with an average age of 78.6 years ranging from 70 to 102 years. All the 28 patients were treated with minimally invasive operations with locking compression plates. The time from injury to operation was ranged from 3 to 8 days (with an average of 4.5 days).</p><p><b>RESULTS</b>The operation time was from 40 to 90 minutes (with an average of 55 minutes). The average bleeding volume during the operation was 70 ml (from 50 to 150 ml). One patient died during hospital stay. Twenty-five patients were followed up from 6 months to 2 years with an average of 15 months after operation. The fracture healing time was from 10 to 12 weeks (10.4 weeks in average). According to an evaluation standard of HUANG Gong-yi, the results were excellent in 20 cases,good in 4 cases, poor in 1 case.</p><p><b>CONCLUSION</b>Minimally invasive approaches with LCP could treat the elder intertrochanteric fractures with the advantages such as minimal invasive, stable fixation and less blood loss.</p>

Comparison of the sleep architecture and symptom of inattention-hyperactivity in children with obstructive sleep apnea hypopnea syndrome before and after surgery / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To observe the symptoms of inattention, hyperactivity among obstructive sleep apnea hypopnea syndrome (OSAHS) children, also to investigate the effects of surgery (tonsillectomy and adenoidectomy or adenoidectomy alone) on the changes of sleep architecture and inattention-hyperactivity score (IHS).</p><p><b>METHODS</b>Between June 2004 and may 2007, eighty children diagnosed as OSAHS with overnight polysomnography (PSG) were included in this study, only sixteen children had complete pre-op and post-op PSG data. Thirty children with vocal cord nodules were selected as control group. DSM-IV-derived IHS was evaluated by neurologist. All OSAHS children accepted surgery (tonsillectomy and adenoidectomy or adenoidectomy alone) and IHS evaluation. The pre-op and post-op sleep architecture and IHS were compared with that of control group.</p><p><b>RESULTS</b>(1) The median IHS 80 OSAHS children was higher than that it in control group (0.89 vs 0.17) and the difference was significant (Z = -4. 276, P < 0.05). After surgery, it showed a significant reduction in IHS (0.44 vs 0.89, t = 6.219, P < 0.05). (2) Twenty-five OSAHS children had pre-op IHS greater than 1.25 and nine had post-op IHS greater than 1.25, while only three children in control group had IHS greater than 1.25. The difference was statistically significant (chi2 = 5.192, 9.56 respectively, P < 0.05). (3) For sixteen OSAHS children who had both pre-op and post-op PSG data, a decrease in the percentage of phase 1 sleep and an increase in the percentage of phase 2 sleep, slow wave sleep (SWS) and rapid eye movement (REM) sleep were observed in six months after surgery and the difference was significant (t = 12.2, -5.4, -6.3, - 8.1 respectively, P < 0.001). After surgery, apnea-hypopnea index (AHI) decreased from 13.9 times/h to 1.5 times/h while lowest saturation of blood oxygen (LSaO2) increased from 0.855 to 0.940 (t = 5.3, - 3.7 respectively, P < 0.01). REM sleep percentage and LSaO2 was still lower than that of control group six months after surgery.</p><p><b>CONCLUSIONS</b>Children with OSAHS showed significantly impaired attention and hyperactivity as compared with control group. Improvement of behavior and sleep architecture were observed after adenoidectomy and tonsillectomy.</p>

Overnight sleep structure of children with epilepsia / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To evaluate the effect of epilepsy on sleep in children.</p><p><b>METHODS</b>Whole night polysomnography was performed in 48 epileptic children and 12 healthy controls. The 48 epileptic children were divided into focal seizure and generalized seizure groups and into waking seizure and sleeping seizure groups according to the time of occurrence of the seizures. Various parameters of sleep structure were analyzed.</p><p><b>RESULTS</b>The sleep efficiency of epileptic children was significantly lower than that of the healthy controls (85.4 +/- 8.6% vs 90.9 +/- 5.8%; P < 0.05). The total recording time (TRT) of sleep was significantly longer and the sleep efficiency was significantly lower in the focal seizure group compared to the control group (P < 0.05). The percentage of stage 1 non-rapid-eye-movement sleep (S1 sleep) increased and the percentage of rapid-eye-movement (REM) sleep decreased in the generalized seizure group compared to the control group (P < 0.05). The percentage of S1 sleep increased and both the percentage of REM sleep and the sleep efficiency decreased in the sleeping seizure group as compared with the control group (P < 0.05). There were no significant differences in the parameters of sleep structure between the waking seizure and the control group. Among the sleeping seizure group, the children with generalized seizure showed significantly lower REM sleep percentage and sleep efficiency, and those with focal seizure had significantly longer TRT and higher S1 sleep percentage as compared with the controls.</p><p><b>CONCLUSIONS</b>Epilepsy affects sleep structure of patients, and different types of seizure have different influences on sleep structure. Children with generalized seizure have prolonged light sleep and shortened REM sleep. When generalized seizures occur during waking, the increase of light sleep is more pronounced. While generalized seizures occur during sleeping, REM sleep reduction is more prominent. Children with focal seizures have decreased sleep efficiency. When focal seizures occur during waking, the sleep structure of patients is normal. However, when seizures occur during sleeping light sleep increases and sleep efficiency decreases.</p>

<p><b>OBJECTIVE</b>To examine the prevalence and characteristics of aortic arch calcification (AAC) in residents aged 50 or over in Guangzhou, China.</p><p><b>METHODS</b>Face-to-face interview, physical examination and laboratory tests were conducted on 10 413 Chinese adults aged 50 or over. Posterior-anterior plain chest X-ray radiographs were obtained from 10 305 subjects using a Toshiba KSO-15R machine. The radiographs were reviewed together by two radiologists while 300 radiographs were independently gone through by two radiologists to assess the agreement with Kappa coefficient method.</p><p><b>RESULTS</b>The rate of agreement on Diagnosis for the two radiologists was 85.0% and Kappa coefficient was 0.68, with P < 0.001 which showed a moderate agreement between the two radiologists. Among the 10 305 subjects, there were 3064 men and 7349 women, with their mean age (+/- standard deviation) as 64.0 +/- 6.0 and 66.2 +/- 5.8, respectively. Most of them had educational level of middle school or below, and most of their occupations were factory or agricultural workers. The prevalence of AAC was 40.6%. Women showed significantly higher prevalence rate than men (41.4% versus 38.6%, P < 0.001) and the prevalence of AAC increased significantly with age. Subjects with primary educational level or below had the highest prevalence of AAC. There was no significant association found between occupation and AAC prevalence. 98.7% of the subjects with AAC occurred in aortic arch. Most AAC had a length of 10 mm or longer and a width from 1-4 mm, which indicated the severity of AAC among the subjects.</p><p><b>CONCLUSION</b>The prevalence of AAC among Guangzhou Biobank Cohort was about 40.6%, higher than those reported in foreign studies, while most of the lesions were quite serious.</p>
