BACKGROUNDChronic kidney disease (CDK) is a worldwide health problem, but there is currently no effective treatment that can completely cure this disease. Recently, studies with mesenchymal stem cells (MSCs) on treating various renal diseases have shown breakthroughs. This study is to observe the homing features of MSCs transplanted via kidney artery and effects on renal fibrosis in a reversible unilateral ureteral obstruction (R-UUO) model.

METHODSThirty-six Balb/c mice were divided into UUO group, UUO-MSC group, and sham group randomly, with 12 mice in each group. The MSCs had been infected by a lentiviral vector to express stably the luciferase reporter gene and green fluorescence protein genes (Luc-GFP-MSC). Homing of MSCs was tracked using in vivo imaging system (IVIS) 1, 3, 14, and 28 days after transplantation. Imaging results were verified by detecting GFP expression in frozen section under a fluorescence microscope. E-cadherin, α-SMA, TGF-β1, and TNF-α mRNA expression in all groups at 1 and 4 weeks after transplantation were analyzed by quantitative PCR.

RESULTSTransplanted Luc-GFP-MSCs showed increased Luciferase expression 3 days after transplantation. The expression decreased from 7 days, weakened thereafter and could not be detected 14 days after transplantation. Quantitative PCR results showed that all gene expressions in UUO group and UUO-MSC group at 1 week had no statistical difference, while at 4 weeks, except TGF-β expression (P > 0.05), the expression of E-cadherin, α-SMA, and TNF-α in the above two groups have statistical difference (P < 0.01).

CONCLUSIONIVIS enables fast, noninvasive, and intuitive tracking of MSC homing in vivo. MSCs can be taken home to kidney tissues of the diseased side in R-UUO model, and renal interstitial fibrosis can be improved as well.

OBJECTIVETo study the regulatory effect of Bushenfang on the serum testosterone (T) level of naturally aging rats and its mechanism, in order to provide a theoretical and experimental basis for the clinical treatment of late onset hypogonadism (LOH) in males.

METHODSThirty-two 18-month-old male SD rats were randomly divided into four groups of equal number, naturally aging model and low-, medium- and high-dose Bushenfang groups, and another eight 4-month-old rats were taken as normal controls. The rats of the aging model and normal control groups were treated with normal saline, while those of the low-, medium- and high-dose Bushenfang groups received intragastrically Bushenfang at 3.25, 7.50 and 15.00 g/kg, respectively, all for 3 weeks. Then the rats were sacrificed, the histomorphologic changes of the testis observed by HE staining, the serum T level measured by radioimmunoassay, and the expressions of the StAR protein, P450scc and 3beta-HSD I determined by RT-PCR.

RESULTSThe number of Leydig cells was obviously increased after Bushenfang treatment. The levels of serum T were significantly higher in the low-, medium- and high-dose Bushenfang groups ([6.74 +/- 1.56] nmol/L, [8.50 +/- 1.99] nmol/L and [12.41 +/- 2.91] nmol/L) than in the model group ([3.48 +/- 0.75] nmol/L) (P < 0.05). The three Bushenfang groups also showed a remarkable elevation in the mRNA expressions of StAR (0.74 +/- 0.29, 0.83 +/- 0.32 and 1.35 +/- 0.50), P450scc (0.72 +/- 0.36, 1.023 +/- 0.30 and 1.41 +/- 0.37) and 3beta-HSD I (0.58 +/- 0.14, 0.72 +/- 0.07 and 0.85 +/- 0.18), as compared with the models (StAR: 0.44 +/- 0.09; P450scc: 0.33 +/- 0.05; 3beta-HSD I: 0.34 +/- 0.02), with significant differences in the StAR expression between the high-dose Bushenfang and the model groups, as well as in P450scc and 3beta-HSD I expressions between the medium- and high-dose Bushenfang and the model groups (P < 0.05).

CONCLUSIONBushenfang could improve the pathological status of testicular injury and increase the expression of testosterone synthetase, which might be the mechanism behind its regulatory effect on the serum T level of aging rats.

OBJECTIVETo investigate the clinical results of pedicle-screw placement and reduction on the level of injured vertebrae in treating thoracolumbar fractures.

METHODSFrom March 2006 to May 2009, 27 patients with thoracolumbar fractures were treated with short-segment fixation system and pedicle-screw placement on injured vertebrae through posterior approach. There were 19 males and 8 females with an average age of 36 years old ranging from 24 to 68 years. Eleven patients were injuried by traffic accident, 9 patients were injuried by falling from high, 5 patients were injuried by crush from weighty object, 2 patients were others injuries. Thoracolumbar fractures were classified according to Gertibein classification: 2 cases were of type A1, 3 cases A2, 12 cases A3, 5 cases B1, 5 cases B2. Among them, 14 cases were accompanied with spinal cord injuries,functional assessment of nerves was assessed according to Frankel criteria: 5 cases were of grade B, 3 cases C, 6 cases D. Lumbago according to Denis standard, grade P5 was in all cases. The injured level of 5 cases was in T11, 11 cases in T12, 8 cases in L1, 3 cases in L2. From injury to operation it was 2-15 days with an average of 4 days. The ratio of vertebral height between anterior and posterior border, anteroposterior Cobb angle were compared before and after operation. Function of nerves and index of lumbago were evaluated by Frankel and Denis classification.

RESULTSAll patients were followed up from 14 to 17 months with the mean of 15.5 months. At final follow-up,according to Frankel score system to evaluate function of nerve,2 cases were of grade B, 4 case grade C, 3 cases grade D, 5 cases grade E; according to Denis score system to evaluate index of lumbago, there was P1 (without pain) in 17 cases, P2 (between whiles minute pain, need not treatment) in 8 cases, P3 (moderate pain, between whiles need medication) in 2 cases. The ratio of vertebral height between anterior and posterior border from preoperatively 0.32 +/- 0.14 to postoperatively 0.85 +/- 0.03 (P<0.01); anteroposterior Cobb angle from preoperatively (25.3 +/- 7.8) degrees to postoperatively (11.1 +/- 1.5) degrees (P<0.01). At final follow-up, the ratio of vertebral height between anterior and posterior border, anteroposterior Cobb angle were respectively 0.81 +/- 0.06 and (11.8 +/- 1.9) degrees, there was no significant difference between postoperative and at final follow-up (P>0.05). No complications such as infection, internal fixation failure,nerve injuries were found during follow-up.

CONCLUSIONPosterior short-segment fixation system and pedicle-screw placement on level of injured vertebrae is one kind of effective method in treating thoracolumbar fracture, which can maintain corrective effect and obtain better clinical outcomes.

Objective To investigate the frequency of CD4~+CD25~+FoxP3~+regulatory T cells (Treg)and the expression of the functional protein,FoxP3,in patients with active tuberculosis and the relationship between Treg and the pathogenesis of tuberculosis.Methods Forty-five patients with active tuberculosis(including 25 cases of pulmonary tuberculosis and 20 tuberculous lymphadenitis), 20 healthy controls,20 recovered tuberculosis patients and 6 patients with reactive hyperplasia in cer- vical lymph node were enrolled.The frequency of CD4~+ CD25~+ FoxP3~+ Treg in the peripheral blood was measured by flow cytometry.FoxP3 mRNA expression was determined by real-time reverse transcriptase-polymerase chain reaction(RT-PCR)and the expression of FoxP3 protein in lymphoid tissues was measured by immunohistochemistry.Results The frequency of natural Treg in the peripheral blood from the patients with active tuberculosis was 2.91%?0.23%,which was signifi- cantly higher than that of healthy control group(1.22%?0.18%)and recovered tuberculosis patients(1.50%?0.17%,P

A patient referred to our hospital, diagnosed with left idiopathic chronic orchialgia, was evaluated with a thorough medical and psychiatric history, physical examination, scrotal ultrasound and magnetic resonance imaging. Conservative management failed. The patient had temporary pain relief after undergoing outpatient cord block three times. Microsurgical denervation of the left spermatic cord was operated in March, 2011. A pain questionnaire was used to determine efficacy before and after operation, and complete pain relief was noted at one week after operation. The follow up period was 12 months, at the end of which the pain score was still zero. No complications, including testicular atrophy and hydrocele, occurred. Microsurgical denervation of the spermatic cord can be a minimally invasive, safe and effective management option for treatment of idiopathic chronic orchialgia.

Sarcopenia,osteoporosis and osteosarcoporosis,which belong to the same category of musculoskeletal unit disease,seriously impair the homeostasis of the musculoskeletal system in the aging process of the human body.In recent years,researchers have applied various emerging technologies to conduct multi-disciplinary,multi-level and multi-dimensional research on musculoskeletal decay disease,and have come to realized that the disease involves complex biochemical and mechanical crosstalk,and the intestinal microecology has also aroused great interest in this crosstalk because of its profound impact on musculoskeletal health.In view of this,this paper takes the close relationship between intestinal microecology and musculoskeletal decay disease as the starting point,and under the guidance of the overall concept,we deeply analyzes the mechanism and regulatory information behind this relationship,and on this basis,we excavates the potential therapeutic targets for musculoskeletal decay disease,so that we can provide new ideas and strategies for the management of the disease in the context of the musculoskeletal subunit.

OBJECTIVETo investigate the effect of Compound Xuanju Capsule (CXC) combined with bromocriptine on hyperprolactinemia-induced erectile dysfunction (ED).

METHODSWe randomly assigned 46 patients with hyperprolactinemia-induced ED to receive bromocriptine (trial group, n = 23) and bromocriptine plus CXC (control group, n = 23), respectively, both for 12 weeks. Then we compared the two groups of patients in erectile function and the levels of serum prolactin and testosterone.

RESULTSAfter 12 weeks of treatment, the IIEF-5 scores were significantly improved in both the trial and the control groups as compared with the baseline (19.5 +/- 4.1 vs 13.0 +/- 3.8 and 16.4 +/- 3.7 vs 13.7 +/- 3.5, P<0.05), the level of serum prolactin was remarkably decreased ([156.07 +/- 26.31] vs [478.35 +/- 62.28] mIU/L and [164.73 +/- 28.58] vs [445.26 +/- 57.83] mIU/L, P<0.05), while the level of serum testosterone was markedly increased ([15.34 +/- 5.27] vs [3.80 +/- 1.09] nmol/L and [12.02 +/- 2.36] vs [4.07 +/- 1.25] nmol/L, P<0.05). Post-treatment erectile function was significantly better in the trial than in the control group (P<0.05), and the post-treatment serum testosterone level remarkably higher in the former than in the latter (P<0.05), but there was no significant difference in the serum prolactin level after treatment between the two groups (P>0.05).

CONCLUSIONThe combination of Compound Xuanju Capsule and bromocriptine is highly effective in the treatment of hyperprolactinemia-induced ED, and its effect is even better than that of bromocriptine alone.
