Objective To investigate the effects of vitamin D on synthesis and secretion of lubricin in chondrocytes at the cellular level. Methods Rat articular chondrocytes were stimulated by TNF-α. Normal and inflammatory chondrocytes were treated by different doses of vitamin D respectively. ELISA and Western Blot were used to detect the secretion of lubricin in the supernatant and the synthesis level in the cells. Results TNF-α significantly reduced the activity of both normal chondrocytes and chondrocytes in inflammatory state. TNF-α also significantly reduced the expression of lubricin in the cells and supernatant. 1α,25(OH)2D3 increased the activity of both normal chondrocytes and chondrocytes in inflammatory state. 1α,25(OH)2D3 significantly elevated the secretion and expression of supernatant and intracellular lubricin only in chondrocytes stimulated by TNF-α in a dose-dependent manner, but not in normal chondrocytes. Conclusions Vitamin D can promote the secretion and expression of lubricin in inflammatory state chondrocytes, which may act as one of the mechanisms of vitamin D protecting the cartilage surface in osteoarthritis.

BACKGROUND:The outcome of cardiopulmonary resuscitation (CPR) may depend on a variety of factors related to patient status or resuscitation management. To evaluate the factors influencing the outcome of CPR after cardiac arrest (CA) will be conducive to improve the effectiveness of resuscitation. Therefore, a study was designed to assess these factors in the emergency department (ED) of a city hospital.METHODS:A CPR registry conforming to the Utstein-style template was conducted in the ED of the First Affiliated Hospital of Wenzhou Medical College from January 2005 to December 2011. The outcomes of CPR were compared in various factors groups. The primary outcomes were rated to return of spontaneous circulation (ROSC), 24-hour survival, survival to discharge and discharge with favorable neurological outcomes. Univariate analysis and multivariable logistic regression analysis were performed to evaluate factors associated with survival.RESULTS:A total of 725 patients were analyzed in the study. Of these patients, 187 (25.8%) had ROSC, 100 (13.8%) survived for 24 hours, 48 (6.6%) survived to discharge, and 23 (3.2%) survived to discharge with favorable neurologic outcomes. A logistic regression analysis demonstrated that the independent predictors of ROSC included traumatic etiology, first monitored rhythms, CPR duration, and total adrenaline dose. The independent predictors of 24-hour survival included traumatic etiology, cardiac etiology, first monitored rhythm and CPR duration. Previous status, cardiac etiology, first monitored rhythms and CPR duration were included in independent predictors of survival to discharge and neurologically favorable survival to discharge.CONCLUSIONS:Shockable rhythms, CPR duration ≤15 minutes and total adrenaline dose ≤5 mg were favorable predictors of ROSC, whereas traumatic etiology was unfavorable. Cardiac etiology, shockable rhythms and CPR duration ≤15 minutes were favorable predictors of 24-hour survival, whereas traumatic etiology was unfavorable. Cardiac etiology, shockable rhythms, CPR duration ≤15 minutes were favorable predictors of survival to discharge and neurologically favorable survival to discharge, but previous terminal illness or multiple organ failure (MOF) was unfavorable.

OBJECTIVETo explore the prognostic value of hyperuricemia for adverse events in patients >40 years old receiving valve replacement surgery for rheumatic aortic valve disease.
METHDSConsecutive middle-aged and elderly patients receiving aortic valve replacement surgery for rheumatic aortic valve disease between March, 2009 and July, 2013 were recruited in this study. The patients were divided into hyperuricemic group and normouricemic group based on their serum levels of uric acid, and the clinical data and adverse events within 1 year after the surgery were compared between the 2 groups.
RESULTSA total of 632 consecutive patients were recruited, including 381 patients with hyperuricemia and 251 with normouricemia. The in-hospital mortality rate was significantly higher in hyperuricemic group than in normouricemic group (7.6% vs 2.0%, P=0.002). Serum uric acid levels were negatively correlated with eGFR (r=-0.421, P<0.001) and positively correlated with C-reactive protein level (r=0.093, P=0.025). Multivariate analysis showed that hyperuricemia was independently associated with the in-hospital mortality (OR=3.07, 95%CI: 1.13-8.37, P=0.028) and mortality at 1 year after the surgery (HR=3.14, 95%CI: 1.30-7.62, P=0.011) after adjusting for potential risk factors including age, NYHA III-IV and postoperative acute kidney injury (AKI). Kaplan-Meier analysis showed that the cumulative rate of 1-year mortality after surgery was significantly higher in patients with hyperuricemia (Log-rank=11.73, P=0.001).
CONCLUSIONHyperuricemia is a predictor of in-hospital and one-year mortality in middle-aged and elderly patients following aortic valve replacement surgery for rheumatic aortic valve disease.

INTRODUCTIONHigh workload volumes in a Cytogenetics laboratory can lead to long result turn-around times (TAT). This study aimed to improve laboratory efficiency by adopting Lean Management System initiatives to increase productivity through the elimination of wastes. This study examined if the prerequisite 20-cell analysis was sufficient for a conclusive result or if additional cell workup was necessary to ascertain the presence of a previous chromosome abnormality among cases on follow-up, or when a single abnormal cell was encountered during the analysis to determine the presence of a clone.
MATERIALS AND METHODSThe karyotype results of cases that had additional workup were retrieved from among 8040 bone marrow cases of various haematological disorders performed between June 2003 and June 2008.
RESULTSOf 8040 cases analysed, 2915 cases (36.3%) had additional cell workup. Only 49 cases (1.7%) led to the establishment of a clone. The majority of these cases could have been resolved without the additional workup, especially if fluorescence in situ hybridization (FISH) or polymerase chain reaction (PCR)-based assays had been utilised.
CONCLUSIONThis study shows that the additional workup procedure is redundant. The time saved by discontinuing the workup procedure can be used to analyse other cases, leading to increased laboratory efficiency and a faster TAT without compromise to patient care. The practice of additional workup over and above the 20- cell analysis should be dispensed with as little benefit was derived for the amount of additional manpower expended. FISH or PCR-based assays should be utilised to elucidate a case further.

OBJECTIVE:
To observe the clinical efficacy of thunder-fire moxibustion combined with mifepristone for ovarian chocolate cyst dysmenorrhea with kidney deficiency and blood stasis.
METHODS:
Seventy patients were randomly divided into an observation group and a control group, 35 cases in each group. The patients in the the control group were treated with oral administration of mifepristone, 10 mg each time, once a day; based on the treatment of the control group, the patients in the observation group were treated with thunder-fire moxibustion at Guanyuan (CV 4), Zigong (EX-CA 1), Xuehai (SP 10), once every other day. Both the groups were treated for 3 months. The Cox menstrual symptom scale (CMSS) score, the maximum cross-sectional area of ectopic cyst, and the serum levels of transforming growth factor-β1 (TGF-β1) and interleukin-17 (IL-17) were observed before and after treatment in the two groups. The clinical efficacy was evaluated.
RESULTS:
Compared before treatment, the severity scores and duration scores of CMSS as well as the serum levels of TGF-β1 were reduced after treatment in the two groups (
CONCLUSION
Thunder-fire moxibustion combined with mifepristone could significantly improve dysmenorrhea symptoms, shorten dysmenorrhea time and promote atrophy of ovarian heterotopic cyst in patients with ovarian chocolate cyst dysmenorrhea of kidney deficiency and blood stasis, and the mechanism may be related to the reduction of serum levels of TGF-β1 and IL-17.

OBJECTIVE:
To assess the clinical effectiveness of acupoint application (AP) of Guan Xin Su He Pill (, GXSHP) for patients with chronic stable angina pectoris (CSAP).
METHODS:
This study was carried out in 3 local hospitals in Chengdu, China. After baseline evaluation, eligible patients were randomly assigned to the placebo application for acupoints (PAA) group or the herbal application for acupoints (HAA) group. Patients in the HAA group underwent AP with herbal powder, which was mainly GXSHP, and patients in the PAA group underwent AP with sham drugs. For each treatment session, unilateral acupoints including Neiguan (PC 6), Danzhong (RN 17), Xinshu (BL 15) and Jueyinshu (BL 14), were stimulated for both groups. AP was performed 3 times a week with a 2-day interval for 4 weeks. The primary outcome was the frequency of angina pectoris attacks per week, while the secondary outcomes included angina pain intensity measured by the Visual Analogue Scale (VAS), dose of rescue oral drugs (nitroglycerin), scores on the Seattle Angina Questionnaire (SAQ), Self-Rating Anxiety Scale scores (SAS) and Self-Rating Depression Scale scores (SDS). Clinical outcomes were measured at week 0, 4 and 8. The safety of AP of GXSHP treatment for CSAP were assessed.
RESULTS:
A total of 121 patients were enrolled. Baseline characteristics were comparable across the 2 groups. After treatment, the angina attack numbers in the HAA group were significantly reduced from 11.00 to 4.81 (P<0.05). While, for PAA group, the angina frequency was not significantly improved (baseline 10.55; post-treatment 11.05). The HAA group had significantly fewer angina attacks than the PAA group (P<0.05). Pain intensity measured by VAS in HAA group was significantly reduced from 4.06 to 3.02 (P<0.05). While, for PAA group, the VAS was significantly increased (baseline 3.62; post-treatment 3.96; P<0.05). Clinical outcomes showed better improvement after treatment in the HAA group than in the PAA group in terms of oral administration of rescue drugs, SAS, SDS and SAQ scores (P<0.05). The adverse events were also reported.
CONCLUSION
AP of GXSHP is a safe and effective treatment for CSAP patients (Registration No. NCT02029118).

OBJECTIVE:
To obtain three-dimensional intraosseous artery of the hamate and to provide the vascular anatomy basis of hamate fracture fixation.
METHODS:
PbO (lead monoxide, Sinopharm Chemical Reagent Beijing Co. Ltd) was ground into particles less than 40 μm and suspended in turpentine oil (Chemical Reagent Beijing Co. Ltd) at ratios of 1 g : 1.5 mL, 1 g : 1 mL and 1 g : 0.5 mL. Three specimens were investigated. Brachial arteries were cannulated and perfused with lead-based contrast agent. Hamates were harvested and scanned using micro-computed tomography (microCT). The acquisition protocols were as follows: CT scan setup: total rotation [Degrees], 360; rotation steps, 360; X-ray detector setup: transaxial, 2048; axial, 2048; exposure time, 1 500 ms, Binning, 1; system magnification: high-med. X-ray tube setup: 80 kV, 500 mA current. The down-sampling factor used in the reconstruction was 2. The effective voxel size of the final image was 27.30 μm. The three-dimensional model of the hamate was generated and the distribution and pattern of vessels were evaluated.
RESULTS:
There were abundant extraosseous vessels around the hamate. They were mainly running in the tendons and ligaments around the hamate. Four vascular zones were identified on the hamate surface. They were on the palmar platform of the hamate body, on the dorsal side, on the ulnar side and on the tip of hamulus, namely. There were anastomoses among 4 vascular zones. We did not observe any vessels penetrating through the articular cartilage. The extraosseous vessels of the vascular zones gave a number of intraosseous branches into the hamate. The hamate body received intraosseous blood supply from the dorsal, palmar and ulnar while the hamulus from the palmar, ulnar and hamulus tip. There were some intraosseous branches anastomosing with each other.
CONCLUSION
The extraosseous and intraosseous vessels of the hamate were more than what used to be considered. The hamate body and hamulus received blood supply from multiple directions and arteries anastomosed extensively both outside and inside the hamate, making it possible that the intraosseous perfusion survived after fracture. It is likely that the nonunion after the hamate fracture is not caused by the vascular damage but the malalignment of the fragments.
