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 establish a method for determining glyphosate in the air of workplaces by ion chromatography.

METHODSUltra-fine glass fiber filter paper was used to collect glyphosate from the workplace air. After being ultrasonically eluted with deionized water, samples were determined by ion chromatography using a conductivity detector.

RESULTSWithin the range of 0.05-1.00 mg/L, a linear relationship was found with a limit of detection of 0.003 mg/m(3). The minimum detectable concentration was 0.000 41 mg/m(3) (calculated by sampling 75 L of air). For three different concentrations of glyphosate, the intra-batch relative standard deviations (RSDs) were 1.8%, 1.6%, and 0.8%, respectively, and the inter-batch RSDs were 1.9%, 2.1%, and 2.2%, respectively. The recovery rate ranged from 94.8% to 97.4%. The elution efficiency ranged from 94.5% to 96.7%. The sampling efficiency was 100%. Samples could be stored at room temperature for at least 7 days.

CONCLUSIONThis presented method meets the requirements of Guide for establishing occupational health standards-Part 4: Determination methods of air chemicals in workplace and is feasible for determination of glyphosate in the air of workplaces.

OBJECTIVETo evaluate the effect of intraoperative continuous nimodipine infusion on cerebral vasospasm during intracranial aneurysm surgery.

METHODSThirty consecutive patients under-going intracranial aneurysmal surgery were prospectively randomized into two groups: Isoflurane (group A, n = 15) and nimodipine (group B, n = 15). The patients in group A were maintained with 1 minimum alveolar concentration (MAC) isoflurane anesthesia during the whole procedure. The patients in group B were given nimodipine infusion continuously (20 microg.kg(-1).h(-1)) after induction of anesthesia and anesthetized with 1 MAC isoflurane. S100B levels in cerebrospinal fluid were determined before aneurysm clipping and 0, 2, 4 h after aneurysm clipping by enzyme linked immunosorbent assay. Assessment of mean blood flow velocity of parent arterial and arterial branches were performed before and after aneurysm clipping.

RESULTS(1) S100B in cerebrospinal fluid was increased significantly at 4 h after aneurysm was clipped in group A (F = 4.11, P < 0.05). However, S100B in cerebrospinal fluid was stable in group B in the whole procedure. (2) Mean arterial flow velocity of parent vessels in group B was lower significantly than that in group A (t = 2.08, P < 0.05). However, mean arterial flow velocity of distal vessels in both groups has no significant difference.

CONCLUSIONIntraoperative nimodipine infusion may prevent cerebral vasospasm during intracranial aneurysm surgery.

OBJECTIVETo evaluate the curative effect of curved cutter stapler (Contour, Ethicon Endo-Surgery, Inc) in the ultra low anterior resection for low rectal cancer.

METHODSClinic data of 56 patients with low rectal cancer from Dec. 2005 to Sep. 2006 were reviewed retrospectively. After total mesorectal excision (TME) and lateral lymph node dissection (LLD) in 56 cases, the rectal (anal) remnant was cut and closed with curved cutter stapler (Contour), and preserved for ultra low colo-rectal (anal) anastomoses with 33 mm straight intraluminal stapler.

RESULTSThere was no operational death and the mean hospitalization time was (11.2+/-3.2) days. The incidence rate of postoperative complications in 1 month was 3.57% (2/65). Both of the cases were anastomotic leakage. One was cured by surgical drainage, the other combining with rectal vaginal fistula was cured by transverse colostomy.

CONCLUSIONCurved cutter stapler has the advantages of complete cutting, safe closure and low anastomotic leakage rate in the process of ultra low anterior resection for low rectal cancer.
