Objective To study the clinical features and diagnostic analysis of 30 cases with refractory myco-plasma pneumonia.Methods 60 patients with mycoplasma pneumonia treated in our hospital during 2012.03 to 2014.03 were selected, and 30 cases were diagnosed as normal mycoplasma pneumonia and the others as refractory mycoplasma pneumonia.The clinical manifestations, percentage of neutrophils, peripheral blood leukocytes , C -re-active protein (CRP) level, and chest radiographic were retrospectively analyzed , and the clinical judging indicators of refractory mycoplasma pneumonia were obtained by multivariate logistic regression analysis .Results Considering the time of fever, the difference between two groups was statistically significant (χ2 =12.27, p <0.01).The differ-ence of percentage of neutrophils , peripheral blood leukocytes and CRP between the two groups were all significant (p <0.05); Logistic regression analysis showed that time of fever >10 d, CRP >40 mg /L, appearance of large high -density lung opacities were the judging indicators of mycoplasma pneumonia refractory .Conclusion Time of fever, CRP level and imaging Findings are the judging indicators of mycoplasma pneumonia refractory .

Objective To investigate the treatment effect of daily low dose of sildenafil treating interstitial cystitis .Methods 68 patients with interstitial cystitis in our hospital from June , 2012 to December, 2013 were divided into observation group and con-trol group by digital randomized method, 34 cases in each group.Observation group adopted daily dose of sildenafil 0.25 g treatment every day, and control group adopted the same dose of starch placebo every day.Two groups were treated for 3 months.Curative effect, micturition number a day before and after the treatment, the maximum bladder capacity, interstitial bladder inflammation shape index and problem index score ( ICSI, ICPI) , pelvic pain and urinary frequency score ( PUF) and quality of life scores ( QOL) of two groups were compared.Results The rate of significant curative effect and total effective rate of observation group were significantly higher than that of the control group, and the difference was statistically significant (p<0.01).Micturition number every day, the maximum bladder capacity, ICSI, ICPI, PUF and QOL scores of the two groups before treatment had no statistical significant differ-ences(p>0.05).Maximum bladder capacity and QOL scores of observation group after treatment were (265.44 ±43.85) ml and (44.15 ±4.69) respectively, which were higher than the (92.45 ±25.71) ml and (22.14 ±2.97) of the control group after treat-ment and (94.12 ±23.95)ml and (22.38 ±3.18) of observation group before treatment;Urine per day, ICSI, ICPI and PUF of ob-servation group after treatment is lower than that of the observation groups after treatment and that of the control group before treat-ment, and the difference had statistically significant (p<0.05).Conclusion Daily low dose of sildenafil for treating women with in-terstitial cystitis is worthy of clinical use for it can effectively relieve clinical symptoms and improve patient's life quality.

The changes of the spinal cord blood flow(SCBF),the content of TXB2 and 6-keto-PGF1a of the injured segment of the cord and other neurological manifestations were observed on a rat model of spinal cord injury(SCI)established with Allen's weight drop(50g-cm)method and the effects of indomethacin on these changes were studied.It was found that SCBF was significantly reduced in the first 2 hours after SCI and further reduced in the 4th ~ 8th hour.Increase of TXB2 was observed in the 1st hour and reached the peak in the 4th hour.The level of 6-keto-PGF1a was also increased in the 1st hour and maintained at that level for 24 hours.The changes of TXB2/6-keto-PGF1a was similar to those of TXB2.There was a negative correlation of SCHF with TXB2 content and TXB2/6-keto-PGF1a ratio.The intravenous injection of 10mg/kg indomethacin could inhibit the increase of TXB2 content and increase 6-keto-PGF1a content relatively.It could also alleviate or retard the decrease of SCBF after SCI and improve the motar function of the hind limbs of the rats.These findings suggest that indomethacin can improve SCBF and promote the recovery of neurological functions through its regulatory effects on the levels of TXB2 and 6-keto-PGF1a

To explore the characteristics of hematological abnormalities in patients with systemic lupus erythematosus (SLE) through retrospective analysis.A total of 445 SLE patients were recruited and divided into 5 groups of low white blood cell,immune thrombopenic purpura,anemia,pancytopenia and control without hematological abnormalities.Among them,351 (78.9％) had hematological abnormalities and 94 (21.1％) without hematological abnormities.The prevalence of anemia,leucocytopenia,thrombocytopenia and pancytopenia were 56.0％ (246/445),27.6％ (123/445),13.5％ (60/445) and 8.5％ (38/445) respectively.The incidence of renal damage in anemia group was significantly higher than that in control group (P ＜ 0.01).SLE patients with hematological abnormalities had lower complement C3 levels (P ＜ 0.05) and higher systemic lupus erythematosus disease activity index (SLEDAI) (P ＜ 0.01).Anemia is the most common findings in SLE patients with hematological abnormalities who have lower complement C3 levels and higher SLEDAI.

This study was aimed to establish an identification method between leaflets of Dimocarpus longan and leaflets of Litchi chinensis. The leaflet morphological-venation pattern (LMVP) and quantitative analysis were reliable identification method for Chinese herbs. The results showed that the main differences of leaflets of Dimocarpus lon-gan were the eucamptodromous camptodromous pinnate venation; the secondary veins gradually changed into little near margin and a few brochidodromous; the type of tertiary vein was percurrent or reticulate. The main differences of leaflets of Litchi chinensis were brochidodromous camptodromous pinnate venation; the course of the secondary veins was sinuous or zigzag, and abruptly curved then linked; the type of tertiary vein was reticulate. With three groups of key differences mentioned above, both plants can be successfully identified from each other. The accuracy of identification results (AC) was from 98.1% to 100%. The agreement rate for observation (ARO) was from 98.5% to 100%. And the Kappa value was from 0.97 to 1.00. It was concluded that the established LMVP is simple, rapid, e-conomic and reliable in the identification between leaflets of Dimoc arp us longan and leaflets of its confused herb Litchi chinensis.

Purpose To explore the value of three vessels and trachea view in rapid screening of aortic arch malformations. Materials and Methods 51 fetal subjects who were prenatally diagnosed with aortic arch abnormalities were enrolled, and their diagnoses were confirmed by postnatal echocardiography or autopsy results after induction. Targeted fetal cardiac examinations were conducted under obstetric ultrasound examination conditions, ultrasound images were restored and compared with sonographic features of normal aorta. Results Among the 51 fetus cases with aortic arch anomalies, right-oriented aortic arch with left subclavian artery vagus was shown in 17 cases, left-oriented aortic arch with right subclavian artery vagus in 2 cases, double aortic arch in 2 cases, aortic arch disarticulation in 6 cases, and aortic arch coarctation in 24 cases. Diagnostic accuracy of ultrasound was 94.1%. Sonographic changes were displayed in three-vessel or three vessels and trachea view in all cases. Conclusion Three vessels and trachea view plays an important prompt role in ultrasound diagnosis for fetal aortic arch abnormalities. But when it is manifested as the“1oo”sign, it will be rather difficult for the differential diagnosis of aortic arch disarticulation and severe aortic arch coarctation.

Objective To observe the clinical efficacy of therapeutic method of eliminating phlegm, tranquilizing and calming wind on essential hypertension (EH) with accumulation of phlegm-wetness and influence on biochemical parameters. Methods One hundred cases of EH were selected and randomly divided into the treatment group and the control group (50 cases for each group). The two groups were given the same western treatment. The therapeutic method of eliminating phlegm, tranquilizing and calming wind (with recipe of eliminating phlegm, tranquilizing and calming wind) was given to the treatment group additionally. The course of treatment was 60 days. Grade of phlegm-wetness syndrome, blood pressure (BP), rhythm of the heart (HR), blood lipid, uric acid (UA), blood-glucose, fasting insulin and C-reactive protein of the two groups before and after treatment were observed and compared. Results BP in the two groups were improved after treatment, and BP in the treatment group was improved more than that in the control group (SBP P=0.000, DBP P =0.049). HR in the treatment group was improved notably than that in the control group (P =0.000). After treatment, the blood-glucose, fasting insulin and C-reactive protein in the treatment group were improved notably compared with those in the control group (the former P =0.001, the latter two P=0.000). UA, TC, LDL-C and HDL-C in the treatment group after treatment were improved in comparison with those before treatment (P =0.000). Conclusion On the basis of western treatment, the therapeutic method of eliminating phlegm, tranquilizing and calming wind can improve BP, HR and C-reactive protein in the patients of EH with accumulation of phlegm-wetness, and it can probably improve the blood lipid and UA to some extent.

Objective To observe the effect of Dengzhan Xixin injection on prevention and intervention of cardiovascular and cerebrovascular system disease of older people caused by metabolic disorder. Method A Group with metabolic syndrome were treated with a mixture of 30～40 mL of Dengzhan Xixin injection in 250 mL of physiological saline by intravenous injections (n=52). A treatment session was one injection once a day for 10～14 days. Each session was repeated every six months for a duration of three years. Cardiovascular and cerebrovascular disease symptoms, and changes of high sensitivity C-reactive protein (hsCRP) were measured compared with the control group (n=50). Results Compared to the control group, the intervention group had improved symptoms, lower occurrence of cardiovascular and cerebrovascular disease and ruduced hsCRP test result. The difference was significant (P

Mutation and overexpression of the tumor suppressor gene product, p53, is believed to play an important role in the development of human malignant tumors. Many studies shows that overxpression of the mutant p53 gene product is common in human malignant tumours including esophageal cancer. However, the prognostic significance of overexpression of p53 gene is not well defined. In this study, we have investigated the overexpression of p53 gene product in 174 esophageal squamous cell carcinoma collected from Sichuan Cancer Hospital, Chengdu, China. 48.9% of these esophageal squamous cell carcinomas were positive for p53 staining. Correlations of overexpression of p53 with clinicopathological features including histological type and grade, clinical staging, age and sex was analyzed in all specimens. The prognostic significance of p53 stained esophageal squamous cell carcinoma was analyzed in 111 of these patients follow-up for five-year. Significant statistical correlations were observed between p53 positive and poor prognosis analyzed by Cox proportional hazard regression analysis, (F=0.04). No statistically significant differences were observed between p53 overexpression and the clinicopathological factors including age, sex, differentiation and clinical staging of the cancer, but patients with Vositioly expressed p53 has a poorer prognosis than those with negative expression. The present study indicate that overexpression of p53 may be a useful independent prognostic factor in esophageal squamous cell carcinoma at its early stage.

Objectives To evaluate the valproate plasma l ev els,the clinical efficacy and adverse effects in patients with epilepsy treated with the conventional preparations and the sustained-release preparations of sodium valproate (VPA-Na?SR).Methods 33 patients received oral conventional formul ation of sodium valproate for over six months and a similar dosage of VPA-Na?SR for 4 weeks.After 12 or 24 hours,the valproate plasma concentr ations of the two formulations were measured respectively before taking drugs in the early mor ning.The valproate plasma concentrations and the clinical efficacy of the VPA-N a?SR were assessed by comparing with that of conventional valproate.The adverse effects were recorded.Results The average valproate plasma trough concentration was s ignificantly higher in patients receiving VPA-Na?SR than that of those receiving conventional valproate.Seizure free in patients was achi eved by 76%(n=25) with VPA-Na?SR and by 45%(n=15) with conventional valproate resp ectively.There was statistical difference between the two formulations.The seizu re frequency was significantly reduced in 5 patients treated with VPA-Na?SR.A dverse ef fects were observed in 2 patients with conventional valproate,5 patients with V PA-Na?SR whose valproate plasma levels were higher than that of conventional p reparations.Adverse effects were related to increased valproate plasm a levels and individual drugtolerance. Conclusions The advantage of VPA-Na?SR is that serum valproa te con centrations may increase smoothly and minimize fluctuation in serum dr ug concentrations during a dosing interval. It is a more effective and more convenient antiepileptic agent.
