Objective To explore clinical characteristics of severe pre-eclampsia and eclampsia complicated with reversible posterior leukoencephalopathy syndrome(RPLS).Methods Clinical data of 31 cases of severe pre-eclampsia and eclampsia complicated with RPLS were studied retrospectively.ResulIs These 31 cases with RPLS accounted for 48% of those with eclampsia,.and all presented with hypertension,headache and disturbalice of vision,24 cases with seizure episodes,19 cases with nausea and vomiting and 13 with continuous dysphoria after seizure.Neuroradiologic findings showed edema predominantly in the bilateral posterior cerebral white matter,especially in occipital-parietal lobe,with low density lesions in CT and long T1 and T2 signals in brain MRI. Conclusions Severe pre-eclampsia and eclampsia tended to complicate with RPLS,presenting severe hypertension,headache,disturbance of vision and recurrent seizure as major clinical manifestations.

Objective To investigate the surgical techniques of the modified presigmoid trans-partial bony labyrinth approach and the advantages in exposure of the petroclival region and in treat the lesion of this area.Methods By simulate the modified presigmoid trans-partial bony labyrinth approach in 15 adult cadaveric heads with the aid of an operating microscope and record important structures in the petroclival region.Results The petroclival region,the posterior cavernous sinus,Meckel cave,the vertebral-basilar artery,the anterior inferior cerebellar artery,the superior cerebellar artery,ipsilateral Ⅲ-Ⅹ cranial nerve nere fully exposured and contralateral Ⅵ cranial nerve were fully exposured.The range of presigmoid exposure was (19.41 ± 1.58)mm,the exposurein of inferior temporal was (14.18 ± 1.88) nun,the maximum exposure angle of slope center depression was (60.54 ± 6.93) °,the depth of operation was (55.87 ± 4.34) mm.Conclusion The advantages of the modified presigmoid trans-partial bony labyrinth approach can earn enough exposures of deep part of petroclival region and posterior part of cavernous sinus,improved petroclival exposure,multiple axes of visualization,preservation of hearing and facial nerve function,and early devascularization of the tumor.

Moderate to severe unilateral ptosis has previously been treated with levator resection or frontalis sling and cosmetic double fold in the opposite eyelid. This method often resulted in undesirable asymmetrical lid lag phenomenon in down gaze. From December 1991 to December 1994, we treated 65 cases of unilateral ptosis with frontalis sling or levator resection, and simultaneously cosmetic frontalis sling have been performed in the unaffected normal eyes of 41 patients and cosmetic double fold have been performed in the unaffected normal eyes of 11 patients. After 6 months of operation, authors survey the patients content. The number of cases of content were 4(36.36%) in 11 cosmetic double fold group and 31(75.6%) in 41 cosmetic frontalis sling group. The content after cosmetic frontalis sling was higher than cosmetic double fold. Asymmetrical lid lag phenomenon on downward gaze which is inevitable complication postoperatively was reduced by means of cosmetic frontalis sling of unafeected normal eye in unilatral ptosis. The authors expect that the patient will be more satisfied with the result of symmetrical lid lag in down gaze after cosmetic frontalis sling of unaffected normal eye in aesthetic aspect.

Objective To evaluate the treatment effects of middle and proximal phalangeal fractures with lateral fixation of mini-titanium plate.Methods From December 2011 to April 2015,56 patients (64 phalanges) suffered from closed middle and proximal phalangeal fractures were treated with lateral fixation of mini-titanium plate.There were 48 males and 8 females,aged from 17 to 65 years (average,36.3 years).Fractures included 25 cases of middle phalangeal fracture and 39 cases of proximal phalangeal fracture.According to site of fracture,12 cases were middle phalangeal condyle fractur,7 cases were middle phalangeal shaft fracture,6 cases were middle phalangeal base fracture,10 cases were proximal phalangeal condyle fracture,22 cases were proximal phalangeaal shaft fracture and 7 cases were proximal phalangeal base fracture.According to the type of fracture,13 cases were transverse,9 cases were short oblique,11 cases were long oblique,6 cases were spiral and 25 cases were comminuted fracture.All phalangeal fractures were exposed by lateral approach,in which the lateral band and oblique fibers of proximal phalanx were excised to fully expose proximal phalangeal fracture.After the reduction,the fractures were fixed with mini-titanium plate laterally.The Disabilities of the Arm,Shoulder and Hand (DASH)and the bilateral fingers total active motion (TAM) were employed to evaluate the functions.All patients took X ray during follow-up.Results All 56 patients were followed up from 9 to 47 months,average (14 ± 6) months.Phalangeal fractures were healed from 7 to 14 weeks,average (8.8 ± 2.4) weeks without loss of fixation or malunion.At final follow-up,DASH score were from 1.7 to 7.5,with an average of 4.8 ± 2.2.TAM of the fingers was excellent (＞ 90％ TAM of the contralateral side) in 33/64 (51.5％) cases,good (75％-90％ TAM of the contralateral side) in 30/64 (46.9％) cas es,fair (50％-75％ TAM of the contralateral side) 1/64 (1.6％) cases.Conclusion Lateral approach fully exposes middle and proximal phalangeal fractures and less interferes with the extensor mechanism.Lateral fixation with mini-titanium plate could provide stability and allow early motion.This technique may be an optional choice in clinical practice.

Objective To observe the peripheral arterial Doppler flow velocity curve changes and elucidate the blood flow characteristics by adding extra pressure on the limbs,and to provide evidence for better diagnosis of peripheral arterial diseases by ultrasound.Methods Color Doppler ultrasound instrument was used to record the brachial artery(BA),radial artery(RA),common femoral artery(CFA) and popliteal artery(POA) Doppler flow velocity curves both at rest and under different grades of distal and proximal limb pressuring in 40 randomly selected healthy adults.The peak systolic and early diastolic reverse flow velocity(PSV,PRV) and the resistance index (RI) were measured and analyzed.Results Three-phase waveform was seen at rest.Significant changes were noticed in PRV and RI under distal pressuring,while no significant difference was seen in PSV between groups.Conclusions Normal peripheral arteries show pulsed step-by-step blood flow pattern along with the cardiac cycles.Peripheral arterial Doppler flow curves changes regularly with limb grading pressuring.

Viral hepatitis is clinical multiple strong infectious disease, to know characteristics of traditional Chinese medicine and western medicine clinical use in patients with viral hepatitis, the research object of this study is 41 180 cases of hospitalized patients with viral hepatitis in hospital information system from 17 grade A hospitals, using frequency statistics and association rules method to analyze the traditional Chinese medicine and western medicine clinical use information, the drug kinds analysis results: western medicine of reduced glutathione tablets use frequency is highest, 14 079 cases (34.61%), traditional Chinese medicine of diammonium glycyrrhizinateuse frequency is highest, 14 058 cases (34.56%); traditional Chinese medicine and western medicine drug combination in diammonium glycyrrhizinate combined with reduced glutathione tabletsuse frequency is highest, 8 607 cases (25.09%). The mechanism of drug classification results :both traditional Chinese medicine and western medicine are the sort of educed enzyme medicine that has the highest percentage of drug use, traditional Chinese medicine 10 983 cases (27.01%), western medicine, 9 595 cases (23.59%); traditional Chinese medicine and western medicine combination in a kind of medicine to clear heat and promote diuresis combined with educed enzyme drug use frequency is highest, 5 621 cases (13.82%). Through the analysis above, combine traditional Chinese and western medicine therapy for the treatment of viral hepatitis should be given priority. Traditional Chinese medicine to clear heat and promote diuresis combined with western medicine of educed enzyme drug is the most commonly appear in clinical two drug combination scheme, traditional Chinese medicine to clear heat and promote diuresis combined with western medicine of educed enzyme drug and nucleustide analogsis the most commonly appear in clinical three drug combination scheme.

OBJECTIVETo investigate effects of the variation of immune function in high humidity environment in different time, and lay a foundation for further study of the related mechanism.

METHODThirty SD rats were divided into 3 groups (n = 10): 20 day group, 40 day group in 90% relative humidity chamber and control group in normal relative humidity. Peripheral blood and spleens were collected to detect the levels of T lymphocyte subsets by Flow Cytometery.

RESULTSIn peripheral blood of the 20 day group rats, the CD3+ %, CD4+ %, CD8+ % and CD4+/CD8+ were 52.91 +/- 6.27, 37.80 +/- 4.11, 14.85 +/- 3.73 and 2.72 +/- 0.82 separately. Expect CD3+ %, they all had significant differences (P < 0.05). In addition, the data of the 40 day group rats showed no diversity in statistics. In spleen, CD8+ % of the 20 day group rats was 6.23 +/- 2.87 with significant differences (P < 0.05) and IgG, IgA and IgM did not change a lot in blood serum of the high humidity groups except C3 of the 20 days group (P < 0.05).

CONCLUSIONIn high humidity environment, the immune function of the rats increased in the initial stage. As time went on, the immune function gradually went to normal level through the self adjustment.
