Extracapsular cataract extraction (ECCE) with primary posterior chamber intraocular lens (IOL) implantation was performed on 31 cases (38 eyes)of cataract with high myopia of axial length over 26mm and preoperative retinal visual acuity of ≥0.5. They were followed up for 3～26 months. Postoperative visual acuity s. c. was ≥0.5 in 65.8％ of the eyes and visual acuity c.c. was ≥0.5 in 92.1％ and 1.0～1.5 in 52.6％ of the eyes. The results showed that it was fairly possible for cataract patients with high myopia to obtain normal vision after ECCE and IOL implantation when the preoperative retinal acuity was ≥0.5. The calculation of lens power and surgical procedures were described, and the indications for the operation and the managements of complications were discussed as well.

Objective To explore the influences on biological function induced by hyperthermia in human lung cancer cell line H1299, and to investigate the possible molecular mechanism. Methods H1299 cells were cultured in vitro and divided into 2 groups. The cells in culture flasks of hyperthermia group were immersed into a water bath at 43 ℃for 1 h, and the cells of control group were cultured at 37 ℃. The cell growth was detected by CCK8 assay, and the cell cycle and apoptosis rates were detected by flow cytometry [propidium iodide (PI) staining and PI/Annexin V staining]. The effects of hyperthermia on migration and invasion abilities of H1299 cells were determined by Transwell migration and invasion assays, respectively. The expression of LLGL1 was measured by Western blot. Results The cell cycle had no significant difference between the two groups, but the apoptosis rate was significantly higher in hyperthermia group [(24.81 ±2.80) %] than that in control group [(11.73 ±1.55) %] (t= 7.709, P= 0.0021). The migrating cell number was decreased in hyperthermia group (25.67±4.81) than that in control group (85.00±10.31) (t=5.182, P=0.0066). The invasive cell number was also decreased in hyperthermia group (22.00±2.08) than that in control group (108.3.0±10.14) (t=8.342, P=0.0011). The expression level of LLGL1 protein in hyperthermia group was 4.2 times that in control group(t=3.028, P=0.0389). Conclusion Hyperthermia induces the cell apoptosis and inhibits migration and invasion abilities of H1299 cells, which maybe associate with increasing LLG1 expression.

Objective To study the lateral branch of thoracodorsal nerve and the deltoid branch of axillary nerve under microscope for clinical application in the reconstruction of brachial nerve injury. Methods 31 lateral branches and deltoid branches of axillary nerve on 17 cadaver specimens were studied on topography under the light microscope(? 5) to observe the length, diameter, and the number of branches. The number of fibers was counted on the HE- stained section of the nerves. Three cases were performed: In operationⅠ , the lateral branch of thoracodorsal nerve was connected with the deltoid branch of axillary nerve. In operationⅡ , on the base of the first operation, the medial branches of the thoracodorsal nerve partially the latissimus dorsi was reconstructed for recovery of the flexion function of the elbow. In operationⅢ , the latissimus dorsi was section into two parts according to the innervation of the medial and lateral branches of the thoracodorsal, and the two branches of the thoracodorsal were transplanted in a dislplaced position for the restoration of flexion function of the elbow and the fingers. Results Thoracodorsal nerves have 2 branches near dorsal aspect of the latissimus dorsi. The lateral branch is thicker with the average length of 58.2 mm avaliable for the reconstruction purpose; the diameter is in average of 1.46 mm, the number of fibers is in average of 1 519; 90.4％ of the lateral branches redivided into 2 or 3 branches. The diameter of the deltoid branch of axillary nerve is 2.31 mm in average and 61.3％ give 3 branches; 32.3％ 2 branches; the number of fibers is in average of 2 341. Clinically the reconstruction operation is successful. In operationⅠ the strength of the deltoid muscle recovered to grade 4; in operationⅡ the strength of the deltoid muscle and elbow- flexing is reached grade 4 and in operationⅢ the strength of elbow- and finger- flexion recovered to grade 4. Conclusion Reconstruction of two muscular groups of the latissimus dorsi with loss of nerve innervation is effective by the application of double branch potential of the thoracodorsal nerve.

Objective To establish a rapid, accurate and low-cost screening method for the detection of calreticulin (CALR) mutations in myeloproliferative neoplasms (MPN).Methods Seventy cases diagnosed with MPN were collected from 2012 to 2016. PCR combined with high resolution melting (HRM) analysis were used to screen the CALR mutations, and Sanger sequencing and T-A sequencing were applied to verify the HRM positive samples. CALR wild type DNA, type 1 and type 2 mutant DNA samples were selected and analyzed 4 times/day for 5 days to detected the CVs of Tm (melting temperature) respectively. JAK2 mutations were also analyzed in MPN patients to compare the association between JAK2 and CALR mutations.Results PCR-HRM analysis showed 7 cases (26.9%) and 5 cases (20.8%) patients with CALR mutations were screened out from 26 essential thrombocythaemia (ET) cases and 24 primary myelofibrosis (PMF) cases, but no CALR mutations were found in cases with polycythaemia vera (PV). All mutations were confirmed by direct sequencing or cloning sequencing. The CVs for HRM analysis of CALR wild type DNA, type 1 and type 2 mutant DNA samples were 1.91%,1.59% and 1.43%, respectively.There were 47 cases with JAK2 V617F and 1 case with exon12 mutation. No coexistence of JAK2 mutation and CALR mutations were found in a single sample.Conclusion PCR-HRM can be used for rapid screening of CALR mutation. Subsequent sequencing can be applied for rapid diagnosis of MPN patients in clinical practice.

OBJECTIVETo evaluate the effect of microwave sintering on the translucency of zirconia and to compare these effect with those of conventional sintering. The relationship between the microstructure of specimens and translucency was investigated.

METHODSA total of 10 disc-shaped specimens were fabricated from 2 commercial brands of zirconia, namely, Zenostar and Lava. Each group included 5 discs. Conventional sintering was performed according to the manufacturers' specifications. The maximum temperature for Zenostar was 1,490 °C, whereas that for Lava was 1,500 °C. The dwelling time was 2 h. The sintering temperature for microwave sintering was 1,420 °C, heating rate was 15 °C · min⁻¹, and dwelling time was 30 min. After sintering, the translucency parameter (TP) of the specimens were measured with ShadeEye NCC. The sintered density of the specimens was determined by Archimedes' method. The grain size and microstructure of the specimens were investigated by scanning electron microscopy.

RESULTSDensity and translucency slightly increased by microwave sintering, but no significant difference was found between microwave and conventional sintering (P > 0.05). Small and uniform microstructure were obtained from microwave sintering. The mean TP of Lava was significantly higher than that of Zenostar (P < 0.001).

CONCLUSIONThe translucency of zirconia sintered by microwave sintering is similar to that of the zirconia sintered by conventional sintering.
