OBJECTIVETo study Chinese medicine treatment in the three-part of the proximal humerus fractures.

METHODSFrom January 2009 to February 2012, 118 cases of proximal humerus three-part fractures were used two methods of operation and manipulation treatment,that were all acute and closed. In operation group: there were 22 males and 37 females,the mean age of the patients was (65.80 +/- 10.62) years (ranged from 45 to 83 years), and the interval from injury to hospital was (22.58 +/- 22.11) hours (ranged from 1 to 96 hours), used open reduction and locking plate fixation surgery. In manipulation group: there were 21 males and 38 females, the mean age of the patients was (65.98 +/- 11.10)years (ranged from 45 to 85 years), and the interval from injury to hospital was (20.85 +/- 22.63) hours (ranged from 1 to 107 hours), used manipulative reduction and small splinting external fixation. All patients were evaluated with shoulder pain, function, activity and anatomical indicators after treatment.

RESULTSAll patients were followed up for 3 to 12 months with an average of 8.2 months. According to Neer Score, the total scores was 85.47 +/- 6.15 in operation group, 84.95 +/- 5.70 in manipulation group. The satisfaction rate of the operation group were 88.20%, and the manipulation group were 86.40%. The difference was not statistically significant between two groups (P > 0.05).

CONCLUSIONThe two treatment were able to achieve satisfactory results. The manipulative reduction and splinting treatment has the advantage of avoiding the risk of surgery, less blood damage, ensureing the efficacy, and reducing costs. It can effectively treat the proximal humerus three-part fracture.

OBJECTIVETo study the expression of alpha-catenin in the rat testis after intra-testicular testosterone withdrawal induced by injection of testosterone undecanoate (TU).

METHODSTen adult male SD rats received vehicle (n = 5 ) or TU (19 mg/kg every 15 days, n = 5) for 130 days. Paraffin-embedded testicular sections were used for immunohistochemistry against a polyclonal anti-alpha-catenin antibody.

RESULTSIn the control, alpha-catenin was expressed in the acrosome of spermatids and the cytoplasm of Leydig cells and peritubular myoid cells. In the TU-treated rat testis, Leydig cells were atrophied and the expression of alpha-catenin was markedly decreased or absent, but there was no evident change in the immunostaining of spermatids or myoid cells.

CONCLUSIONIntra-testicular testosterone withdrawal-induced looser arrangement or sloughing of spermatogenic cells is not related to the adhesion molecule alpha-catenin. Alpha-catenin may be used as a cell identification marker for Leydig cells.

OBJECTIVE: To systematically evaluate the efficacy and safety of anterior decompression and posterior decompression in the treatment of thoracolumbar fractures with spinal cord injury, so as to provide a good scientific basis for more effective treatment of thoracolumbar fractures with spinal cord injury. METHODS: A clinical data about comparative study of anterior decompression and posterior decompression in the treatment of thoracolumbar fractures with spinal cord injury was searched and collected. The databases of Pubmed, Embase, Cochrane Library, CNKI, CBM, Wanfang Medical Network were searched by computer. Artificially collected journals included Spine, European Spine Journal, The Journal of Bone and Joint Surgery. Two spine surgeons independently screened the literature according to established inclusion and exclusion criteria and assessed the quality of the included studies. Meta-analysis was performed on the data using Review Manager 5.3 software, the indicators included operative time, intraoperative blood loss, postoperative tactile score, postoperative motor score, postoperative vertebral height, hospitalization time, neurological function recovery, efficiency of treatment, postoperative complications. RESULTS: Fifteen randomized controlled trials (RCTs) were enrolled in a total of 1 360 patients, including 680 anterior decompression and 680 posterior decompression. The results of Meta-analysis showed that the anterior decompression group had longer operation time [MD=80.09, 95% CI(36.83, 123.34), P=0.000 3], more intraoperative blood loss [MD=225.21, 95%CI(171.07, 279.35), <0.000 01], longer hospitalization time [MD=2.31, 95% CI(0.32, 4.31), P=0.02]. And the postoperative tactile score [MD=13.39, 95% CI(9.86, 16.92), <0.000 01], postoperative motor score [MD=13.15, 95% CI(7.02, 19.29), <0.000 1], vertebral height [MD=1.36, 95% CI(0.79, 1.92), <0.000 01] in anterior decompression were higher than that in posterior decompression. There was no statistically significant differences in the efficacy of treatment [OR=1.14, 95% CI(0.56, 2.31), P=0.72], neurological recovery [OR=0.87, 95% CI(0.57, 1.33), P=0.52] between two groups. CONCLUSIONS Compared with posterior decompression, the anterior decompression has the advantages of longer operating time, more intraoperative blood loss, longer hospitalization time, higher postoperative tactile score, higher postoperative motor score, and higher injury vertebral height, But there was no significant difference in the treatment efficiency and nerve function recovery between two groups.

OBJECTIVETo study the effect of different blood pressure control targets on hematoma enlargement and prognosis in patients within 48 h after hypertensive cerebral hemorrhage (HCH).

METHODSBetween January, 2013 and July, 2016, 102 patients with HCH were randomized into group A (51 cases) and group B (51 cases) with different systolic blood pressure (SBP) control targets within 48 h. The patients in group A were given early active antihypertensive treatment with SBP control target of 130-140 mm Hg; those in group B received standard antihypertensive treatment with SBP control target of 170-180 mm Hg. The changes in the volume of hematomas and the patients' prognosis were compared between the two groups.

RESULTSAfter 48 h of treatment, SBP, hematoma volume and the National Institutes of Health Stroke Scale (NIHSS) score were significantly lower and Glasgou Coma Scale (GCS) score was significantly higher in group A than in group B (P<0.01 or 0.05). After 30 days of treatment, the patients in group A showed significantly better indicators of treatment efficacy than those in group B (Z=2.331, P=0.020). The mortality rate was lower in group A than in group B, but the difference was not statistically significant (Χ=2.772, P=0.096).

CONCLUSIONEarly active antihypertensive treatment is safe and feasible in patients with HCH and can reduce the enlargement of the hematomas, alleviate deterioration of neurological function, and improve the prognosis of the patients.

OBJECTIVETo study the protective effects of AduoLa Fuzhenglin(ADL) on the heart injury induced by microwave exposure in rats.

METHODSOne hundred forty male Wistar rats were divided randomly into 5 groups: control, microwave radiation, 0.75 g x kg(-1) d(-1) ADL, 1.50 g x kg(-1) d(-1) ADL and 3.00 g x kg(-1) d(-1) ADL pretreatment groups. Rats in three ADL pretreatment groups were administrated by ADL per day for 2w then exposed to 30 mW/cm2 microwaves for 15 min. The left ventricle blood of rats was obtained at 7 d and 14 d after exposure to microwaves, and the blood Ca2+, AST and CK were detected with Coulter automatic biochemical analyzer, then the histological changes and ultrastructure of heart were observed under light and electron microscopes.

RESULTSAt 7 d and 14 d after exposure to microwaves, the blood Ca2+, AST and CK concentrations significantly increased (P<0.05 or P<0.01) as compared with controls; Heart muscle fibers showed wavilness, endotheliocyte karyopyknosis, anachromasis; The mitochondria swelling and cavitation, intercalary dies blurred in radiation groups. The changes in 0.75 g x kg(-1) d(-1) ADL pretreatment group were similar to the radiation group, but in 1.50 g x kg(-1)d(-1) and 3.00 g x kg(-1) d(-1) ADL pretreatment groups, above indexes of rats significantly reduced as compared with microwaves group (P<0.05); also the blood Ca2+, AST, CK contents were significantly lower than those in microwave group (P<0.05); The heart showed a tendency to improve.

CONCLUSIONMicrowave radiation (30 mW/cm2) can cause the blood Ca2+, AST and CK turbulence, and heart injury in the histology and ultrastructure; ADL at the dosages of 1.50 g x kg(-1) d(-1) and 3.00 g x kg(-1) d(-1) has a protective effects on the heart injury induced by microwave in rats.
