BACKGROUND: Absorbable material is a hotspot in orthopedics, which is biodegradable, avoids fixation residues and second surgical trauma compared with the traditional internal fixation.OBJECTIVE: To investigate the clinical efficacy and safety of K-wires, screws and absorbable rods for the internal fixation of Mason II-III radial head fractures.METHODS: Totally 45 patients with Mason Ⅱ-Ⅲ radial head fractures were collected from January 2010 to December 2015 admited in Zhangjiagang First People's Hospital and Zhangjiagang Hospital of Traditional Chinese Medicine, and were then divided into three groups (n=15 per group), followed by implanted with K-wires (group A), screws (group B)and absorbable rods (group C), respectively. The baseline data, operation time, blood loss, healing time, Mayo and Broberg-Morrey scores were compared among groups.RESULTS AND CONCLUSION: (1) There were no significant differences in the baseline data, operation time, blood loss,and healing time among groups (P > 0.05). (2) The Mayo scores in the groups A, B, and C were (88.45±6.22),(92.37±5.60), and (90.82±6.58), respectively; the Broberg-Morrey scores in the groups A, B, and C group were ((90.82±6.83), (93.05±6.54), and (91.68±7.15), respectively; all above scores showed no significant differences among groups (P > 0.05). (4) The total incidence rate of complications in the groups A, B, and C was 20％ (2/15), 13％ (2/15),and 7％ (1/15) respectively, showing no significant difference among groups (P > 0.05). (4) These results indicate that the absorbable rods can obtain satisfactory treatment outcomes for Mason II-III radial head fractures, which is equivalent to the traditional internal fixation. Moreover, it can avoid secondary operation for removing internal fixators and the adverse impact of stress shielding, so it is recommended to be used in clinic.

Culture medium and fermentation conditions for lipid production by Rhodosporidium toruloides were optimized with single factor and uniform design experiment. The best medium recipe was found with 70 g/L glucose, 0.1 g/L (NH4)2SO4, 0.75 g/L yeast extract, 1.5 g/L MgSO4. 7H2O, 0.4g/L KH2PO4, sterilized at 121 degrees C for 15 min, and then supplemented with ZnSO4 1.91 x 10(-6) mmol/L, CaCl2 1.50 mmol/L, MnCl2 1.22 x 10(-4) mmol/L and CuSO4 1.00 x 10(-4) mmol/L. The optimal fermentation conditions were as follows: 50 mL of medium (pH 6.0) in 250 mL Erlenmeyer flask with 10% inoculum (28h) under orbital shaking at 200 r/min for 120h at 30 degrees C. Under these conditions, yeast biomass accumulated lipids up to 76.1%.

AIMTo investigate the effect of ciliary neurotrophic factor (CNTF) on the nuclear translocation of protein kinase C (PKC) following NMDA administration in the primary cultured hippocampal neurons.

METHODS(1) PKCGAMMA or PKCepsilon- immunocytochemistry staining method was used after treating neurons with NMDA or CNTF. (2) The gray of the nucleus of the PKC-positive neurons were measured under the image pattern analysis system.

RESULTS(1) After NMDA administration of different concentration and time, Nucleus appear PKCgamma and PKCepsilon activities, especially the 100 micromol/L NMDA 30 min group. (2) The gray of nucleus in CNTF + 500 micromol/L NMDA group is similar to control group.

CONCLUSIONNMDA can induce nuclear translocation of PKC in the primary cultured hippocampal neurons, and CNTF can inhibit the translocation. It suggests that the inhibition of PKC translocation induced by NMDA is one of the important reasons for the neuro-protective effects of CNTF.

Objective　To investigate the effect of rapid fluid replacement on hemorheology in delayed resuscitation after burn. Methods　A total of 32 dogs inflicted with 40%TBSA full thickness scalding were randomly divided into 4 groups: scald control group(C group), delayed Gelofusion even replacement group (GE group), rapid fluid replacement group (GR group), and delayed plasma rapid fluid replacement group (PR group). The femoral arterial pressure, viscosity of blood and plasma, packed cell volume and aggregation of RBC were detected at the intervals of before and 2, 6, 8, 12, 24, 36 and 48 hours after scalding. Results　The viscosity of blood markedly increased at 2 hours after scalding, and the hemorheology parameters decreased after fluid resuscitation. The hemorheologic parameters were obviously lower in GR group than in GE group at 2 hours after rapid resuscitation, the viscosity of blood and RBC aggregation in GR group were obviously lower than those in PR group. Conclusion　Under the condition of delayed resuscitation after burn, rapid fluid replacement can quickly decreased the state of blood high viscosity and may play a role in improving microcirculation and treating burn shock.

OBJECTIVETo observe the therapeutic effects of acupuncture at Neiguan (PC 6) on silent myocardial ischemia (SMI).

METHODSForty patients with SMI were randomly divided into an electroacupuncture group and a medicine group, 20 cases in each group. The Electroacupuncture group was treated with electroacupuncture and Neiguan (PC 6) was selected as the main acupoint, and the other acupoints were selected by syndrome differentiation. The medicine group was treated with oral administration of compound Danshen dripping pill. The total effective rate, heart rate, blood pressure and dynamic electrocardiogram in 24 h were compared.

RESULTSThe total effective rate of 95.0% (19/20) in the electroacupuncture group was better than that of 75.0% (15/20) in the medicine group (P < 0.05). After treatment, the heart rate, systolic blood pressure and diastolic blood pressure in the two groups were decreased significantly (P < 0.01, P < 0.05) and the electroacupuncture group was superior to the medicine group (all P < 0.05). The SMI duration and the number of ST segment depression were decreased significantly in both groups after treatment (P < 0.01, P < 0.05) and the electroacupuncture group was superior to the medicine group (P < 0.05).

CONCLUSIONAcupuncture at Neiguan (PC 6) has a good therapeutic effect on SMI. It can decrease the heart rate and blood pressure, reduce the afterload in left ventricular and is superior to that of compound Danshen dripping pill.

OBJECTIVETo observe the effect of targeted argon-helium cryoablation on portal region of the liver in dogs by observing the pathological changes in the first-order branches of the Glisson ductal system.

METHODSTwelve healthy dogs underwent percutaneous targeted argon-helium cryoablation of the liver and sacrificed at 3 and 28 days after the cryoablation to observe the pathological changes in target area for cryoablation and the first-order branches of the Glisson ductal system.

RESULTSNo obvious damage was not found in the vascular wall of the portal vein by gross or microscopic observation, but the liver tissue in the vicinity of the blood vessels showed total necrosis. In spite of the injuries of different degrees in the first-order bile duct system after argon-helium cryoablation, no severe damages such as perforation or full-thickness necrosis occurred in bile duct wall, and most of the injuries were temporary and reversible. The size of the ablated area on day 28 was significantly reduced as compared with that on day 3 following the cryoablation (P<0.05). In the acute stage after the cryoablation (1-3 days), ALT and AST levels increased significantly in (P<0.05) but recovered 1-4 weeks later (P>0.05). The cryoablated area was basically consistent with the pathological area that underwent necrosis (P>0.05).

CONCLUSIONTargeted argon-helium cryoablation can cause total destruction of the liver tissue around the blood vessel without damaging the vascular walls of the portal vein. Argon-helium cryoablation induces relatively minor injuries to the bile duct of hepatic portal section and does not obviously damage the liver function, and the scope of tissue necrosis can be estimated according to the size of frozen area observed. Argon-helium cryoablation is a safe and minimally invasive operation with reliable therapeutic effect.

OBJECTIVETo investigate the expression and its significance of retinoic acid receptor-beta (RAR-beta) in colorectal cancer.

METHODSRAR-beta was detected by immunohistochemistry methods and carcino-embryonic antigen (CEA) was tested by chemiluminescence immunoassay methods in normal tissues, paracancerous tissues and colorectal cancer tissues of 60 patients with colorectal cancer treated from January 2006 to January 2007. Above-mentioned data, together with the clinicopathological data of these 60 patients, were analyzed to figure out the expression and its significance of RAR-beta in colorectal cancer.

RESULTSThe expression rate of RAR-beta in tumor tissues (48%) was significantly lower than those in both normal tissues (87%) and paracancerous tissues (87%) (P < 0.05). And its expression was also significant lower in patients with lymph node metastasis (32%) and patients with advanced cancer (TNM stage III and IV) (29%) than in those without lymph nodes metastasis (60%) and those with early stage cancer (stage I and II) (69%). There was no significant differences among well, mildly and poorly differentiated cancer tissues. The CEA level rose in 20 patients, and its rising rate was remarkably higher in patients with lymph node metastasis (48%) and in patients with advanced cancer (52%) than those without lymph node metastasis (23%) and in early stage(14%).

CONCLUSIONSThe expression of RAR-beta decreases significantly in cancer tissues in patients with colorectal cancer, which may be related to the carcinogenesis of colorectal cancer; and its decreasing degree is correlated negatively with the lymph node metastasis and advanced clinicopathological stage. The expression level of RAR-beta may be a new prognostic indication of patients with colorectal cancer.
