Objective To evaluate the changes of hypersplenism patients with post-hepatitis cirrhosis and hypertension who treated by partal splenic embolization.Methods 24 patients with hypertension and hypersplenism were treated by PSE.In the operations we measured the free portal pressure(FPP).Before and after the operation,all patients diameter and velocity of portal veins and splenic veins were measured by Doppler ultrasonography.Results Compared with the condition before operation,the FPP decreased 3.2?0.4 mmHg,the quantity of blood flow of portal veins from 1104 ml/min dropped to 793 ml/min,and that of splenic veins from 897 ml/min dropped to 355 ml/min.Conclusion PSE can improve the state of hyperdynamic circulation of portal veins system in a little time.

Chinese Journal of Postgraduates of Medicine 2015;38(4):273-275
Objective To explore the clinical significance of serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and plasma D-dimer (D-D) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and stable chronic obstructive pulmonary disease (COPD).Methods The clinical data of 76 patients with AECOPD (AECOPD group) and 68 patients with stable COPD (stable COPD group) were analyzed retrospectively.Serum NT-proBNP,plasma D-D levels and arterial blood gas analysis were measured and compared.Results The levels of serum NT-proBNP and plasma D-D in AECOPD group were (918 ± 271) ng/L and (0.269 ±0.048) mg/L,in stable COPD group were (264 ± 32) ng/L and (0.223 ± 0.042) mg/L.The levels of serum NT-proBNP and plasma D-D in AECOPD group were significantly higher than those in stable COPD group (P < 0.01).The levels of serum NT-proBNP and plasma D-D were negatively correlated with arterial blood oxygen partial pressure (r =-0.181,P =0.030;r =-0.166,P =0.047),and were positively correlated with arterial blood carbon dioxide partial pressure (r =0.763,P < 0.01;r =0.424,P < 0.01).Conclusion Combined detection of serum NT-proBNP and plasma D-D has important clinical significance in evaluating severity of COPD,and may indicate AECOPD.

Objective To compare the clinical efficacy of minimally invasive removal of intracranial hematomas and medical con-servative treatment for hypertensive cerebral hemorrhage .Methods A total of 75 patients with hypertensive cerebral hemorrhage were collected and randomly divided into two groups according to the treatments :38 patients treated with conservative medicine and 37 patients treated with minimally invasive removal of intracranial hematomas based on standard drug therapy .Neurological impair-ment and recovery of self-care ability of patients in both groups before and after three weeks and six weeks of treatment were scored by National Institute of Health Stroke Scale (NIHSS) .Changes of diffusion tensor imaging before treatment and after two weeks of treatment were evaluated by fractional anisotropy value (FA) .Results There was no significant difference between neurological im-pairments of the patients in two groups before treatment .But the recovery degree of functional impairment and muscle nerve in min-imally traumatic treatment group was more significant than those in the conservative medical treatment group after treatments . There was significant difference between two groups (P< 0 .05) .Conclusion Minimally traumatic of hematomas is an effective method of treating hypertensive intracerebral hemorrhage .

Objective:To explore the correlativity between facial morphologic angles of Xi'an youths.Methods:60 Xi'an residents aged 18 -40 years(30 males and 30 females)with normal facial profile,without operation and trauma experience,received 3dMD scaning.12 morphologic angles were measured.Data were statistically analysed by SPSS 19.0 software.The correlative relationship and formulas of facial angles were studied.Results:Nasofrontal angle of the males was larger than that of the females(P <0.05), the other angles showed no difference between sexes(P >0.05).Correlativity between each pair of 5 angles was concluded by a logic diagram(R≥0.7),the correlativity of 4 pairs was positive and 3 negative.Conclusion:The facial morphologic angles of Xi'an youths are correlated and coordinated.

OBJECTIVE:
To investigate the correlation between tongue body MRI measurements and the lingual region obstruction in patients with obstructive sleep apnea hypopnea syndrome (obstructive sleep apnea hypopnea syndrome, OSAHS), and the relationship of two diagnosis methods in positioning obstructive level, in order to improve the preoperative diagnostic accuracy of obstructive level in OSAHS patients .
METHOD:
Fifty-nine patients with OSAHS definited by the AG200 sleep apnea monitoring and obstruction plane positioning system was included. They all underwent tongue MRI scan, after three-dimensional reconstruction, the tongue body length to diameter, relative thickness, basal diameter, wide around central about wide diameter and tongue body volume were measured. The lower blocking (mainly composed of lingual region) constituent ratio P established by AG200 was correlated with tongue parameters measured by MRI. At the same time, To analysis of differences of P in patients with different degree of OSAHS.
RESULT:
Among these patients with OSAHS in different degree, the coefficient correlation between tongue parameters(tongue length, relative thickness, basal diameter, wide middle diameter, tongue body volume) and lower blocking constitute ratio P werer LP = 0.051,rHP = 0.069, r1 = 0.215, r2 = 0.147, rVP = 0.259, respectively. lower obstruction of form than the differences had statistical significance. The measured tongue parameters and value P(the lower blocking constituent ratio) were negatively correlated, which demonstrated that exclusing of the larynx and hypopharynx airway obstruction, the lower airway obstruction detected by AG200 was related with tongue parameters measured by MRI, and was strongestly related with the tongue body volume.
CONCLUSION
The volume of tongue and AG had correlation in judgement of lower blocking. In OSAHS patients the lower blocking constituent ratio varies between the defferent severity groups of the disease, the combina tion of the two method can be used to predict the obstructive plane in OSAHS patients with upper airway obstruction, and provide the basis for the individual treatment of patients with OSAHS.

Objective To study the association of biallelic polymorphism at position 196 in exon 6 of tumor necrosis factor receptor 2(TNFR2) gene and coronary artery disease(CAD).Methods A retrospective case control study was designed in this investigation.Patients with angiographically proven CAD (n=142)and coronary atherosclerosis(n=215)were compared to healthy volunteers(n=631). Genotyping was performed by ShineRoar probes analysis.Results People with GG genotype at position 196 in exon 6 of TNFR2 gene have more risks of development of CAD(OR=2.556,95% CI:1.051~6.218, χ2=4.57,P=0.033)and CA(OR=2.547,95% CI:1.162~5.579,χ2=5.81,P=0.016) than those with TT genotype.Further analysis after adjustment for sex and age demonstrated that GG genotype was not associated with CAD(OR=0.614,95% CI:0.166~2.279,χ2=0.53,P=0.466)and coronary atherosclerosis(OR=O.644,95%CI:0.200-2.069,χ2=0.55,P=0.459).Conclusion Tumor necrosis factor receptor 2 gene polymorphism at position 196 in exon 6 was not an independent risk factor of development of CAD and coronary atherosclerosis among Han Chinese.

OBJECTIVE To investigate the application of near-total laryngectomy on the treatment of advanced laryngeal and hypopharyngeal carcinoma. METHODS Thirty patients with laryngeal carcinoma(T3N0~T3N1 17cases,T4N0~T4N1 13cases) and nine with hypopharyngeal carcinoma(T3N0~T3N1 6cases,T4N0~T4N1 3cases) were treated with near-total laryngectomy from May 1995 to March 2003 according to Peaeson modifying method of Tangpingzhang. Concurrent neck dissection were performed in sixteen patients. RESULTS The speech function was obtained in 36 cases (92.3 %) and good swallowing function was obtained in 38 cases(97.4%). Three year survival rates were 73.3% (22/30) in laryngeal carcinoma and 55.6 %(5/9)in hypopharyngeal carcinoma and five year survival rate in laryngeal carcinoma was 61.1%(11/18) . Local recurrence rate was only 2.56 %. CONCLUSION Near-total laryngectomy and speech rehabilitation can be used in most cases that might be treated with total laryngectomy in the past. It can provide satisfying survival rate, good swallowing and speech function.
