OBJECTIVETo study the clinical efficacy of semiextended intramedullary nailing of the tibia using a suprapatellar approach for proximal tibial fractures.

METHODSFrom January 2013 to January 2014, a total of 16 patients with unilateral proximal tibial fractures, 14 males and 2 females, underwent closed reduction and internal fixation with TRIGEN™ META-NAIL™ via the suprapatellar approach. The average age was 42.2 years old (ranged, 26 to 57 years old). Radiographic and clinical follow-up examinations were performed at a minimum of 1 year after surgery. Measurements included surgery time, complications, bone healing time, tibial alignment, knee range of motion, pain scoring (visual analogue scale) and functional outcome (Lysholm knee score).

RESULTSThe average surgery time was (75.7±8.3) minutes (ranged, 65 to 95 minutes). No obvious complications were recorded. Average duration of follow-up was (15.6±8.1) months (ranged, 12 to 24 months). Fifteen patients attained radiological bone union for a mean time of (3.6±1.8) months (ranged, 3 to 5 months). At the final follow-up, all tibial alignments were good, and no patients complained of anterior knee pain. Mean arc of knee motion was (124.4±18.8) degrees for the affected extremity compared with (127.5±16.7) degrees for the contra-lateral knee. The total scores of Lysholm knee score ranged from 77 to 92, average 86.4±12.3.

CONCLUSIONFor proximal tibial fractures,the semiextended intramedullary nailing technique via a suprapatellar approach can obtain satisfactory clinical outcomes with simplicity in reduction and fixation, minimal complications, and good recovery of limbs function.

AIM: To investigate the characteristics of pathological injury and its relationship with the transformation of energy metabolism of hypertrophic cardiomyocytes after hypoxia-reoxygenation. METHODS: Cultured rat cardiomyocytes were induced to be hypertrophy by angiotensin Ⅱ (Ang Ⅱ) and norepinephrine (NE). Glucose oxidation rate (GOR), glucolysis rate (GLR) and fatty acid oxidation rate (FOR) were determined by liquid scintillation counting, and cell apoptosis was detected by TUNEL. RESULTS: (1) Compared with the normal cardiomyocytes (NC), the GOR and GLR were slightly higher and the FOR was slightly lower in the group of hypertrophic cardiac cells (HC) than that in the group of normal cardiomyocytes cultured under the normal oxygen partial pressure. The apoptosis rate had no difference between the two groups. (2) The apoptosis rate of hypertrophic cardiomyocytes after hypoxia was significantly higher than that of hypertrophic cardiomyocytes in normal culture. It was higher and moreover, some necrosis cardiomyocytes appeared after reoxygenation. (3) GOR and FOR in both group (NC and HC) were slightly lower in a time-dependent manner after hypoxia than that in each group in normal culture condition. GLR had no difference in both group. The GOR was more lower in both NC and HC group when reoxygenation than that at the point of hypoxia for 2 hours, but the GLR and FOR were significantly higher in HC than that in NC when reoxygenation. (4) The GOR was significantly higher and the GLR and FOR were significantly lower in the hypertrophic cardiomyocytes group (HC) with dichloroacetate (DCA, 1 000 ?mol/L) or trimetazidine (TMZ, 1 ?mol/L) treated respectively than that in the responded hypertrophic cardiomyocytes after stimulation by hypoxia-reoxygenation. In the meanwhile, the apoptosis rate also was markedly lower in the treated hypertrophic cardiomyocytes group. CONCLUSION: The transformation of energetic metabolism pathway plays an important role in the pathogenesis (mainly the apoptosis) of the hypertrophic cardiomyocytes after hypoxia-reoxygenation.

To explore the depression in type 2 diabetic patients treated with insulin and compared to those treated with oral anti-diabetic drugs.283 type 2 diabetics were seclected randomly from outpatient and inpatient departments of endocrionology in Jiangsu Province Hospital of Traditional Chinese Medicine,with the self-designed questionnaire and Zung self-rating depression scale to conduct the survey.Comparisons between the two groups were carried out with t-test or x2 test for quantitative and qualitative data,respectively.Logistic regression were used for the analysis of the relationship between the therapeutic regimen and depression.Overall,43.1％ of the type 2 diabetic subjects showed depressive symptoms in different degrees.Compared to the oral drug group,the insulin group showed a significantly higher prevalence of depressive symptoms (insulin group,53.5％,oral drug group,30.5％;P＜0.01)and higher self-rating depression scale scores (insulin group,51.7 ± 12.4,oral drug group,44.8 ± 10.6;P＜0.01).Moreover,after an adjustment for age,sex,body mass index,diabetic duration,complications,HbA1Cand so on,the insulin group showed a significantly higher frequency of depression (OR=4.218,95％ CI 1.764-13.285,P=0.004),compared to the oral drug group.The data showed that insulin treatment is an independent risk factor to the presence of depressive symptoms in type 2 diabetics,and it is necessary to pay more attention to their psychological support.

Objective To evaluate morphological structure of uterosacral ligament (USL) and cardinal ligament (CL) in patients with severe pelvic organ prolapse (POP) by MRI technology, and to analysis and discuss its clinical significance. Methods From November 2013 to February 2014 in Peking University People′s Hospital, 26 elderly patients withⅢ-Ⅳdegree of POP were selected as the POP group and 18 healthy elderly volunteers were selected as the control group during the same period. Pelvic MRI examination were performed in the two groups. The morphological characteristics of left and right side of the uterosacral-cardinal ligament on MRI and the attachment site of the starting and ending points between two group were described and compared. Results In POP group, 25 cases of left USL starting point were located in the sacrospinous ligament/coccygeal muscle complex [58% (15/26)] or coccygeal muscle [38%(10/26)], ending point were located in the cervix and vagina [58%(15/26)] or cervix [38%(10/26)];24 cases of right USL starting point were located in the sacrospinous ligament/coccygeal muscle complex [31%(8/26)]or coccygeal muscle [62%(16/26)], 26 cases of right USL ending point were located in the cervix and vagina [62% (16/26)] or cervix [38% (10/26)]; the left and right CL in the POP group and the control group were both from the sacroiliac joint at the top of the greater sciatic foramen from the ipsilateral pelvic side wall;1 case (4%, 1/26) of left CL in the POP group completely connected to the bladder, 10 cases (38%, 10/26) partly connected to the bladder;14 cases (54%, 14/26) of right CL partly connected to the bladder, the rest ending points of left and right CL were located in cervix and (or) vagina. In the control group, 17 cases of left USL starting point were located in the sacrospinous ligament/coccygeal muscle complex (10/18) or coccygeal muscle (7/18), ending point were located in the cervix and vagina (12/18) or cervix (6/18);18 cases of right USL starting point were located in the sacrospinous ligament/coccygeal muscle complex (10/18) or coccygeal muscle (8/18), ending point were located in the cervix and vagina (13/18) or cervix (5/18);8 cases (8/18) of left CL partly connected to the bladder;15 cases (15/18) of right CL partly connected to the bladder, the rest ending points of left and right CL were located in cervix and (or) vagina. There was no significant difference between the two groups on the starting and ending points (P>0.05). Conclusions The observation of MRI could be consistent with the clinical anatomy on the starting and ending points, direction of travel in the uterosacral-cardinal ligament. The starting and ending points of the left and right side USL and the ending points of the left and right side CL are not completely symmetrical, the variation degree is large, some CL could be completely or partly inserted to the bladder.

Ten cell strains were obtained from the human gastric cancer cell line BGC-823 by using the method of single cell cloning. Through inoculation of these cell strains in nude mice and subsequent observation of their metastatic capability, four cell lines, C_1, C_6 with high, and C_5, C_8 with low metastatic capability were selected out; and their biological and morphological properties were studied. It was demonstrated that all of them did not show apparent difference in growth ability, but morphologically, the mictovilli of C_5 and C_8 cells were scarce and short; and their microfilaments were thick, straight and well organized. Whereas the microvilli of C_1 and C_6 strains were long and abundant comparatively, but their microfilaments were poorly organized. On the basis of present observation,we suggested that the organization of microfilaments in cancer cells appeared to bear reversed relationship with their metastatic capability.
