Objective To explore the significance, indicatinos and complications of emergency tracheotomy for patients with severe craniocerbral trauma. Methods The clinical data of 42 patients with severe craniocerbral trauma were retrospectively analyzed. Results Of them, 20 were basically cured (48%), 12 had improvement (29%) ,3 were released from the hospital(7 % ), 1 survived(2 % ) in a vegetative state,and 6 died(14%). Conclu- sion Emergent tracheotomy should be performed on patients with severe craniocerbral trauma to resolve respiratory tract obstruction, improve air current, prevent cerebral anoxia, prevent and treat pulmonary infection, increase the therapeutic efficacy.

OBJECTIVE To find out the status about detection and drug resistance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) of urogenital tract infection in Shaoxing area of Zhejiang Province.METHODS The detections and drug sensitive tests of Uu and Mh adopting the reagent boxes produced by bioMerieux Company in France were made.RESULTS In 2678 samples of suspicious urogenital tract infection patients,980 samples cultured of mycoplasma were positive,and the positive rate was 36.6%.Among these cases,763 samples(28.5%) were Uu positive;116 samples(4.3%) were Mh positive.In the drug sensitive test,Uu and Mh were most sensitive to PRI,JOS,DOX and TET.To CFLX,OFL,ERY,CM and AM,they had the highest level of drug resistance.CONCLUSIONS The clinical therapy of mycoplasma infection ought to choose the appropriate antibiotics based on the results of the drug sensitive test of the laboratory.

Objective To delineate the speculation that triple combination of small doses of calcium antagonist (levoamlodipine),the ACEI(imidapril)and the ARB(candesartan)may exert more significantly effect on mi- croalbuminuria(MAU)in patients with type 2 diabetes mellitus and hypertension.Methods One hundred sixty ca- ses of consecutive patients with type 2 diabetes mellitus and hypertension were randomized to receive following vari- ous combinations:amlodipine 2.5 mg/candesartan 4 mg(n=40),candesartan 4 mg/imidapril 5 mg(n=40);imidapril 5 mg/amlodipine 2.5 mg(n=40),and amlodipine 2.5 mg/candesartan 4,mg plus imidapril 5 mg(n=40).The changes in blood pressure and MAU were determined before and after treatment.Results Four combinations of treatment all significantly lowered BP(P

Objective To discuss the pathogenesis,diagnosis and treatment of delayed traumatic intracerebral hematoma.Methods The clinic data of traumatic delayed intracranial hematoma patients in this hospital were retro- spectively analyzed.According to clinic observation and CT re-examination,47 cases were diagnosed as delayed trau- matic intracranial hematoma(45 cases by operative treatment,and the other 2 by conservative treatment).Results There were 21 cases of recovery,10 cases of slight disability,8 cases of severe disability,8 cases of death.The total mortality rate was 17 %.Conclusion Brain contusion,subarachnoid hemorrhage and skull base fracture were impor- tant factors of DTICH.Fine-observation and prompt CT re-examination offered excellent results for DTICH.

Objective To observe the morphological changes of rats' pancreas and nitric oxide (NO) and endothelin(ET) in the blood serum in rats after exposure to different pulses of high power pulse microwave (HPPMW).Methods SD-rats were irradiated with 104,105 and 4 × 105 pulses of HPPMW,respectively.After gloss observation,the histopathological changes of pancreas were observed through biological microscope and electroscope.The changes of amylase,nitric oxide and endothelin in blood serum were detected by biochemical and radio-immunological methods. Results Compared with the blank control,no apparent abnormality could be observed in the pancreas of all groups.The dilatation of capillary could be observed in each experimental group by microscope.The ultrastructure changes of pancreas were most serious in 4 × 105 pulse group,especially at 24 and 48 h after irradiation.Compared with the control group,the levels of serum amylase were decreased (F =12.58,11.73,P ＜ 0.05),while ET were increased (F =4.50,4.49,P ＜0.05) at 24 and 48 h after irradiation.The levels of NO in serum were increased ( F =17.51,41.72,19.98,32.64,P ＜ 0.05 ) at each time-point.The level of NO went up with the increase of pulses.Conclusions HPPMW has damage effects on the pancreas in rats.The pulses with the pancreas can lead to severity of the damage. The mechanism of HPPMW may be involved in the enhancement of ET and NO in serum.

Objective To investigate the quality of life and its influencing factors of families primary caregivers of dementia patients .Methods The typically self made questionnaire ,WHO quality of life measurement profile (WHOQOL‐BREF) ,zarit bur‐den of care scale(ZBI) ,social support rating scale (SSRS) et al were adopted to investigate 64 caregivers of AD patients .Results (1) The overall quality of life of family caregivers of total subjective feelings were significantly lower than the general health status of subjective feeling score (t= -2 .217 ,P=0 .030) .The field of physiological and psychology points have no statistically significant difference in comparison with Chinese norm (t= -0 .252 ,-1 .994 ,P=0 .801 ,0 .050);the field of social and environment points have statistically significant difference compared with norm(t= -3 .830 ,3 .658 ,P=0 .000 ,0 .001) .(2) caregiver who have spouse , poor parent child relationship and patients with somatic diseases and mental behavior symptoms have lower quality of life(P<0 .05) .(3)Total score of Quality of life was negatively associated with total score of care burden (r= -0 .433 ,P=0 .000) ,while was significant positive associated with total score of the social support (r=0 .346 ,P=0 .005) .(4)Marital status ,parent‐child rela‐tionship ,physical illness and social support were the main factors affecting the quality of life(r2 =0 .409) .Conclusion Strengthen the social support and psychological intervention of dementia caregivers who has a spouse ,poor parent-child relationship and poor physical condition may help to improve the quality of life .

The diagnosis and treatment of the lacrimal passage obstruction with lacrimal endoscope was investigated and its subsidiary surgical procedures were evaluated. Ninety-three patients (109 eyes) with lacrimal passage obstruction, including presaccal canalicular obstruction (PSCO) and nasolacrimal duct obstruction (NLDO), were examined under a lacrimal endoscope, and the obstructions were treated with laser or micro-drill. All patients were followed up after the operation for 3-6 months. The difference between the laser and the micro-drill treatment was observed. During the period of follow-up, the curative rate was 82.57%. The healing rate in PSCO group and NLDO was 80.36% and 84.91% respectively (P>0.05). After treatment with the laser, the healing rate was 93.33% in the PSCO group and 66.67% in the NLDO group respectively (P<0.05). After treatment with the micro-drill, the healing rate in PSCO and NLDO groups was 65.39% and 94.28% respectively (P<0.01). The lacrimal passage obstruction can be observed and treated directly through the lacrimal endoscope. Choosing different surgical procedures in operation according to the locations of the obstruction is helpful to improve the effectiveness.
