Objective To investigate the level and value of serum uric acid (UA) in patients with multiple system atrophy (MSA).Methods One hundred and one MSA patients were selected as the MSA group and 101 age and sex-matched healthy controls as control group.The UA concentrations and other biochemical indexes were measured by an enzymatic method and carefully analyzed.By comparing the UA concentrations for different genders, subtypes, and different levels of certainty of the MSA group with their counterparts in the control group, we obtained the differences between these two groups and also discussed possible reasons and factors.Results The serum UA levels of MSA patients ((283.74 ± 87.76) μmol/L) were significantly lower than the controls ((317.86 ± 76.95) μmol/L;t =-2.94, P ＜ 0.05).In addition, when the male and female groups were investigated separately, the decrease of serum UA was more significant in the male group compared to the female group (t =-3.88, P ＜ 0.01).Furthermore, by comparing different subtypes of the MSA patients with the control group, we found that the serum UA levels in both P-type or C-type MSA patients were significantly lower than in controls (t =2.92, 2.02;all P ＜ 0.05).By comparing different levels of MSA with the control group, we obtained that UA levels in both probable MSA patients and possible MSA patients were significantly lower than in controls (t =3.13, 2.09;all P ＜ 0.05).By adjusting for the confounding factors, such as age, alanine aminotransferase, aspartate aminotransferase, urea nitrogen, creatinine, high density lipoprotein-cholesterol and low density lipoprotein-cholesterol, the multiple Logistic regression analysis showed that the numbers of MSA patients in the lowest level UA group (UA ＜ 263.0 μmol/L) were higher than the high level UA group (UA ＞ 370.5 μmol/L), though the difference did not reach statistical significance (P ＞ 0.05).Nevertheless, the numbers of male MSA patients in the lowest level and the lower level UA groups (UA =263.0-309.0 μmol/L) were 11.5 and 10.8 times that in the high level UA group (P =0.001, P =0.003).No obviously linear relation between the level of UA and disease progression was found.Conclusions The level of serum UA is significantly decreased in MSA patients, especially in the male patients.The UA, as an antioxidant, may be beneficial to the neurodegenerative diseases.

BACKGROUND: Hemiarthroplasty is widely recommended for the treatment of femoral neck fractures in elderly patients, but it is controversial in choosing cemented or cementless fixation types. OBJECTIVE: To compare the clinical effects of cemented hemiarthroplasty with cementless hemiarthroplasty for the treatment of femoral neck fractures in elderly and to provide a scientific basis for the selection of clinical prosthesis. METHODS: 167 elderly patients with femoral neck fractures undergoing hemiarthroplasty in the Foshan Hospital of Traditional Chinese Medicine from March 2013 to March 2015 were enrolled in this study. According to the type of prosthesis, patients were divided into cementless group (n=81) and cemented group (n=86). The operation time, intraoperative blood loss, hemoglobin levels 1 day after surgery, reoperation rate, mortality and complications at 1 year after surgery were compared. After surgery, clinical function of hip joint was assessed by Harris scoring system. The pain was evaluated by Visual Analogue Scale. RESULTS AND CONCLUSION: (1) All patients were followed up for ≥ 12 months. (2) The operation time in the cementless group was significantly shorter than that in the cemented group (P < 0.01). (3) There was no significant difference in the intraoperative blood loss and hemoglobin levels at postoperative 1 day (P > 0.05). (4) There were no significant differences in Harris hip scores and Visual Analogue Scale score at various time points between both groups (P > 0.05). (5) The incidence of thigh pain in cementless group was slightly higher than that in cemented group at 1 week, 1 and 6 months after operation, but the differences were not statistically significant (P > 0.05). Two patients died from myocardial infarct in the cementless group, and one patient died from pulmonary infection in the cemented group. The mortality was not significantly different at postoperative 1 year between the two groups (P > 0.05). No complications, such as prosthesis loosening and sinking, periprosthetic fracture, and periprosthetic infection, which needed to be refurbished, occurred in both groups. (6) Our findings suggest that both cemented and cementless hemiarthroplasties can obtain satisfactory effect in the treatment of femoral neck fractures in the elderly patients. Cementless hemiarthroplasty can significantly shorten operation time.

This work was mainly studied the effects of the four alkaloids from Coptidis Rhizoma on the mouse peritoneal macrophages in vitro and preliminarily discussed the regulating mechanisms. The effect of alkaloids from Coptidis Rhizoma on the vitality of macrophages was measured by the MTT assay. The effect of alkaloids on the phagocytosis of macrophages was determined by neutral red trial and respiratory burst activity was tested by NBT. The expressions of respiratory-burst-associated genes influenced by alkaloids were detected by qRT-PCR. The conformation change of membrane protein in macrophages by the impact of alkaloids was studied by fluorospectro-photometer. Results showed that the four alkaloids from Coptidis Rhizoma could increase the phagocytosis of macrophages in different level and berberine had the best effect. Berberine, coptisine and palmatine had up-regulation effects on respiratory burst activity of mouse peritoneal macrophages stimulated by PMA and regulatory activity on the mRNA expression of PKC, p40phox or p47phox, whereas the epiberberine had no significant influence on respiratory burst. Moreover, alkaloids from Coptidis Rhizoma could change the conformation of membrane protein and the berberine showed the strongest activity. The results suggested that the four alkaloids from Coptidis Rhizoma might activate macrophages through changing the conformation of membrane protein of macrophages and then enhanced the phagocytosis and respiratory burst activity of macrophages. Furthermore, the regulatory mechanism of alkaloids on the respiratory burst activity of macrophages may be also related to the expression level of PKC, p40phox and p47phox.

OBJECTIVETo observe the efficacy of He-wei Jie-gu (Chinese characters) decoction on femoral intertrochanteric fractures after internal fixation in elderly.

METHODSFrom January 2010 to January 2012, 90 elderly patients with osteoporotic intertrochanteric fracture were randomly divided into two groups. The patients in experimental group were treated with open reduction and internal fixation, He-wei Jie-gu decoction and Caltrate D in oral, including 18 males and 27 females with an average age of (77.8±11.3) years old ranging from 65 to 89 years old;the time from injured to operation was 2 to 9 days with an average of (6.6±2.1) days; according to Evans-Jensen classification, 17 cases were in type I, 8 in type II, 15 in type III, 3 in type IV, 2 in type V. Meanwhile, the patients in control group were treated with open reduction and internal fixation, Caltrate D in oral, including 16 males and 29 females with an average age of (81.2±9.6) years old ranging from 67 to 91 years old; the time from injury to operation was 2 to 10 days with an average of (6.8±2.6) days; according to Evans-Jensen classification, 15 cases were in type I, 10 in type II, 14 in type III, 4 in type W, 2 in type V. The VAS score, hip BMD value before and after treatment, fracture healing and the Harris function score after operation were recorded and compared.

RESULTSAll patients were followed up from 3 to 9 months with an average of (5.6±2.8) months. Compared with the control group, the VAS score of the experimental group had an obviously reduction (F=98.138, P<0.01) after treatment; the hip BMD value at 3 months after treatment in the experimental group was higher than that of the control group (P<0.05); the fracture healing rate of the experimental group was higher than that of the control group (P<0.05); Harris score in 3 months of follow-up in the experimental group was higher than that of the control group (t=2.542, P<0.05); all the differences between two groups were statistically significant (P<0.05).

CONCLUSIONHe-wei Jie-gu decoction can reduce postoperative pain and increase bone mineral density after internal fixation of femoral intertrochanteric fracture in elderly, promote the fracture healing and functional recovery in the hip joint.
