The common, particular structure and the arrangement pattern of the retinula in the compound eye of the housefly Musca domestica have been investigated, and the structures of the retinula cells here been compared with an electron microscope under dark, bright and high intensity light adaptation condition.In general, the retinula of the compound eye is composed of eight retinula cells, but some retinula is composed of six, seven, or nine, ten retinula cells.The arrangement pattern of the retinula in the right, left compound eye and dorsal, ventral regions of the compound eye are the mirror image inversion. But the arrangement pattern of some retinula in the dorsal or ventral region is also the mirror image inversion.The greater part of pigment granules in the retinula cells No.1～6 move towards the rhabdomere, the pigment granules in the retinula cells No.7～8 do not move, but the pigment granules in the some retinula cells No.7～8 move towards the rhabdomere under high intensity light adaptation condition.

Objective To study and find the reason and treatment way of severe encephalocele after operation on the brain. Me thods 15 cases who have severe encephalocele were reviewed retrospec tively.Results Among 15 cases, 12 cases have been cured,3 c ases died with severe pulmonary infection.Conclusion The re asons of severe encephalocele are hydrocephalus?cerebral edema and intracranial infection and it is useful to utilize medicine and other ways to lighten hydroc ephalus?cerebral edema and intracranial infection for the patients who have sev ere encephalocele.

1. The central retinular cells R_7 in the compound eye of male housefly can be divided into two types which are called here R_(7a) and R_(7b) respectively. R_(7a) approximate many features of R_(1-6) cells, which have a larger, cell body, rhabdomere and axon, terminate in the first optic neuropil (lamina). R_(7b) approximate many features of R_8 cell and project directly to the second optic neuropil (medulla). 2. The central retinular cell R_(7a) in the compound eye of male housefly distribute mainly the dorsal region of the eye, there are a few of R_(7a) in the ventral region of the eye, which only distribute in the first and second row ommatidia under equatorial line, but not found in the compound eye of female housefly.

Influences of the clock resolution of bandwidth estimator on the accuracy and stability of the packet pair algorithm was analyzed. A mathematic model has been established to reveal the relationship between the result deviation coefficient and the packet size, clock resolution and real bandwidth (value) of the measured route. A bandwidth self-adapting packet pair algorithm was presented based on the mathematic model to reduce the estimation error resulting from the clock resolution and to improve the accuracy and stability of measurement by adjusting the deviation coefficient. Experimental results have verified the validity and stability of the algorithm.

Objective To evaluate the effectiveness of locking compression plate (LCP) in treatment of comminuted fractures of distal end of radius. Methods A retrospective analysis of the clinical data was done for the 24 patients with comminuted fracture of distal end of radius who had been treated by locking compression plate fixation from August 2002 to August 2003. Results The follow up duration averaged 7.8 months. The satisfactory rate of functional outcome with LCP fixation was 91.6 percent. Conclusion Although LCP can provide the outstanding stability theoretically, it has not resulted in more exciting outcomes in treatment of comminuted fractures of distal end of radius than traditional methods.

Objective To explore the clinical effect of whole body vibration training on stroke patients with hemiplegia and its effect on patients'balance function.Methods Eighty-six stroke patients with hemiplegia admitted to the Second Hospital of Jiaxing from June 2017 to December 2018 were divided into control group (43 cases)and observation group (43 cases) by random number table method.The control group received routine training,while the observation group received whole body vibration training on the basis of the control group.Both two groups were treated for 12 weeks.The changes of upper limb motor function,daily living ability and Berg balance scale (BBS)scores before and after intervention were compared between the two groups.Results After intervention,the FMA scores of the control group and the observation group were (37.89 ± 5.34)points and (49.61 ± 5.47)points,respectively,which were higher than before intervention (observation group:t =21.706,control group:t =10.272,all P ＜0.05).The FMA score of the observation group was higher than that of the control group (t =10.054,P ＜0.05).The improved Barthel index (MBI) scores of the observation group and the control group were (68.98 ± 7.91)points and(52.15 ± 6.87) points,respectively,which were higher than those before intervention (observation group:t =22.170,control group:t =10.119,all P ＜ 0.05).The MBI score in the observation group was higher than that in the control group (t =10.534,P ＜ 0.05).The BBS scores of the observation group and the control group were (59.98 ±6.47) points and (48.98 ± 3.71) points,respectively,which were higher than those before intervention (observation group:t =20.820,control group:t =13.877,all P ＜0.05).The BBS score in the observation group was higher than that in the control group (t =9.672,P ＜ 0.05).Conclusion Whole body vibration training has good clinical effect on stroke patients with hemiplegia,and it can improve upper limb motor function,daily living ability and balance function.

Objective To study the expression of thymus and activation-regulated chemokine(TARC)in the kidney of MRL/lpr mice and to elucidate the molecular pathogenesis of lupus nephritis.Methods The 24-hour urine protein of 4 MRL/lpr mice of 16 weeks of age and 4 age-and sex-matched BALB/c mice was measured.The expressions of TARC mRNA and protein in the kidneys of MRL/lpr mice and BALB/c mice were detected by reverse transcription polymerase chain reaction and Western blot,respectively.Results The 24-hour urine protein and the expression level of TARC mRNA were significantly higher in MRL/lpr mice than in BALB/c mice(P＜0.05).The expression of TARC protein was detectable only in MRL/lpr mice.Conclusion The expression of TARC increases in the kidney of mice with systemic lupus erythematosus,suggesting that TARC may be involved in lupus nephritis in mice.
