OBJECTIVE:To provide reference for medication and chemotherapy in patients with colorectal cancer. METH-ODS:Through retrospective study,case histories and doctor’s advice of the colorectal cancer patients receiving chemotherapy in our hospital during 2011-2014 were consulted to analyze the chemotherapy,medication and irrational drug use. RESULTS:A total of 593 cases of colorectal cancer patients with chemotherapy frequency of 1 940 times were collected to analyze the choice of che-motherapy regimen mainly from the following aspects:indications of chemotherapy,choice of chemotherapy regimen,chemothera-py process and chemotherapy period. There was 409 cases of irrational drug use according to the analysis of drug dosage,selection of solvents and drug concentration,the unqualified rate was 21.08% . CONCLUSIONS:The medication and chemotherapy in pa-tients with colorectal cancer in our hospital are basically rational,but there are still certain problems and shortcomings. In future clinical applications,the medication and chemotherapy need to be improved.

BACKGROUNDHemodynamic evaluation is crucial for the management of patients with pulmonary hypertention. Clinicians often prefer a rapid and non-invasive method. This study aimed to examine the feasibility of transthoracic echocardiography for the measurements of hemodynamic parameters in patients with pulmonary hypertension.
METHODSA prospective single-center study was conducted among 42 patients with pulmonary hypertension caused by different diseases. Transthoracic echocardiography and right-heart catheterization were performed within 24 hours. Pulmonary artery systolic, diastolic and mean pressure (PASP, PADP and PAMP), cardiac output (CO), and pulmonary capillary wedge pressure (PCWP) were measured by both methods. A linear correlation and a Bland-Altman analysis were performed to compare the two groups of hemodynamic parameters.
RESULTSA good correlation was found between invasive and non-invasive measurements for PASP (r = 0.96), PADP (r = 0.85), PAMP (r = 0.88), CO (r = 0.82), and PCWP (r = 0.81). Further agreement analysis done by the Bland-Altman method showed that bias and a 95% confidence interval for PASP, PADP, and CO were clinically acceptable while great discrepancies existed for PAMP and PCWP.
CONCLUSIONSThe non-invasive measurements by PASP, PADP, and CO in patients with pulmonary hypertension correlate well with the invasive determinations. Transthoracic echocardiography (TTE) was inappropriate for estimating PCWP and PAMP.

OBJECTIVETo investigate the methods and effects of secondary intervention for mid-long term complications of endovascular repair (EVR) in aortic diseases.
METHODSFrom May 1999 to Jun 2007, 21 patients with mid-long term complications after EVR were treated in our center. Of these cases, 15 cases received first EVR for abdominal aortic aneurysm (AAA), 3 cases for thoracic aortic aneurysm (TAA) and 3 cases for aortic dissection (TAD). The mid-long term complications included 11 cases of type I endoleak, 4 cases of type II endoleak, 2 cases of type III endoleak and 4 cases of migration of stent grafts. Proximal or distal extensions were used for type I and III endoleak in 9 cases. Fenestrated, scallop and bifurcated stent grafts were used to reconstruct the aortic arch in 3 cases. Emboli technique was used in treating type II endoleak. Thrombectomy and bypass technique were used in 4 cases with stent graft limb occlusion. One ruptured AAA accepted open surgery.
RESULTSSecondary endovascular technique were undergone in 20 (95.2%) cases. One case died in 30 days after the secondary intervention and endoleak remained after the secondary operation in 5 cases. Three cases died of the secondary intervention.
CONCLUSIONSEndoleak and limb occlusion were the chief mid-long complications after EVR. Secondary endovascular technique can be used in most cases and carries great challenges in aortic arch lesions.

OBJECTIVETo determine the safety and efficacy of total percutaneous endovascular abdominal aortic aneurysm repair using the Perclose ProGlide suture-mediated closure system.
METHODSFrom May 2008 to April 2010, 36 abdominal aortic aneurysm patients were undergone total percutaneous endovascular repair. There were 30 male and 6 female patients with a mean age of 68 years. Endografts used included 3 Endurant endografts, 13 Talent endografts, and 20 Zenith endografts. Prior to insertion of the introducer sheath, two ProGlides were pre-set to 18 to 24 F access sites and one to 14 to 16 F access sites. At last, suture the arteriotomy by tying down knots of the ProGlide following removal of the sheath. Technical success, complications, and procedure and access closure times were evaluated. Follow-up protocol consisted of computed tomography angiograms performed at 3, 6, 9, 12 months, and annually thereafter.
RESULTSTwenty patients were operated under local anesthesia and 16 patients under general anesthesia. A total of 68 femoral arteries were closed with 128 devices. Thirty-eight vessels were with 2 devices, while 8 arteries required 3 devices and 2 arteries required 4 devices for hemostasis and an additional 20 vessels only required a single device. Sixty-three (63/68, 92.6%) vessels were closed successfully. Two vessels converted to open closure. Three vessels complicated with hematomas without surgical procedure. The mean follow-up was (12±3) months. There was one asymptomatic femoral artery dissection 3 months after operation.
CONCLUSIONSTotal percutaneous endovascular abdominal aortic aneurysm repair is safe and effective. But it should be performed at hybrid operating room where can convert to open procedure if necessary.

OBJECTIVETo analyze the characteristics of subjective visual horizontal (SVH) and evaluate its clinical value for vestibular function in peripheral unilateral vestibular hypofunction (UVH).
METHODSEighty-five patients with UVH (study group) and 39 normal persons (control group) accepted vestibular function tests, including SVH, subjective visual vertical (SVV) and caloric test by video-nystagmography. The parameters of the angle of SVH and SVV, directional preponderance (DP) and unilateral weakness (UW) of caloric test were observed. The correlation between SVH/SVV, DP, UW and the course of disease were investigated respectively. SPSS 16.0 software was used to analyze the data.
RESULTSReference range of SVH and SVV was from -2° to 2° in the control group. Among the 85 patients, 46 cases (54.1%) and 43 cases (50.6%) had the abnormal values of SVH and SVV respectively, with no statistical significance (χ(2) = 12.5, P = 0.481) by chi square test. Fifty-five cases (64.7%) with abnormal DP had no statistical significance when compared with SVH and SVV respectively (χ(2) values were 0.19 and 2.86, respectively, P value were 0.164, 0.067, respectively). In UVH, there were positive correlation between SVH, SVV and DP (r value was 0.939, 0.648, 0.658, all P < 0.05) respectively, but no correlation between UW and SVH or SVV (r value was 0.048, 0.085, all P > 0.05). According to the permutation and combination of the four parameters, positive or negative, three main groups could be defined [SVH(+)DP(+)UW(+), SVH(-)DP(+)UW(+), SVH(-)DP(-)UW(+); SVV(+)DP(+)UW(+), SVV(-)DP(+)UW(+), SVV(-)DP(-)UW(+)]. The course of disease in the three main groups was positively skewed distribution, with median of 5.0, 10.0, 15.0 d and 5.0, 9.5, 14.5 d respectively. By Kruskal-Wallis Test, χ(2) value were 8.80 and 6.26, respectively(P value were 0.012, 0.040, respectively), with statistical significance between the above three main groups.
CONCLUSIONSThe SVH value can evaluate the function of the otolithic. The angle of SVH and SVV are changing in the course of disease, SVH and SVV can be used as a guidance of the vestibular compensation evaluation.

OBJECTIVETo review the experience of hybrid conventional open and endovascular treatment of thoracoabdominal aortic aneurysm (TAAA), and evaluate the immediate and long term outcomes.
METHODSFrom September 1998 to October 2008, 15 TAAA patients were treated by hybrid-procedures. The mean patient age was 58.7 years (ranged from 44 to 72 years). The aneurysms were Crawford type I in 2, type II in 8, type III in 2, type IV in 3. The median aneurysms diameter was (67.5 +/- 7.5) mm (ranged from 55 to 82 mm). Patients were followed up before dismissal, 3, 6, 12 months later, and annually thereafter.
RESULTSTwo patients were antegrade revascularization, the others were retrograde revascularization. Mean operation time was (8.1 +/- 1.4) h (ranged from 6.8 to 12.7 h), mean blood loss was (956.7 +/- 80.1) ml (ranged from 750 to 3,000 ml). Two patients died during perioperative time, no paraplegia. During follow up revealed shrinkage of aneurysm, no graft migration and paraplegia, but 1 died for acute myocardial infarct.
CONCLUSIONSHybrid treatment is a safe and effective option for treatment of TAAA. Immediate and mid-term outcomes are favorable, but long-term surveillance is indefinite.

OBJECTIVETo discuss the objective characteristics and mechanism of nystagmus direction, intensity and time in horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) .
METHODSA total of 233 patients with HSC-BPPV, whereas 179 horizontal semicircular canalithasis (HSC-Can) and 54 horizontal semicircular cupulolithiasis (HSC-Cup) were involved respectively. The induced nystagmus in roll tests recorded by video-nystagmograph(VNG) , whose direction, intensity and time characteristics were compared in various BPPV.
RESULTSHorizontal nystagmus was both induced by turning left or right in HSC-BPPV roll tests. The direction of the induced nystagmus was the same with turning in HSC-Can. The latency, duration time and intensity ([AKx(-)D] ± s) turning to lesion and normal side were (1.922 ± 1.501)s and (1.447 ± 0.855)s, (25.620 ± 10.409)s, and (22.110 ± 10.931)s, (56.441 ± 33.168)°/s and (24.239 ± 13.892) °/s in HSC-Can. The latency, duration time and intensity turning to lesion side were larger than normal side (t = 3.715, 15.219 and 4.070, P < 0.01) , the difference was statistically significant, and the intensity rate was about 2: 1. The direction of the induced nystagmus was opposite to turning in HSC-Cup. The intensity turning to normal side was larger than lesion side obviously. The intensity rate was about 2: 1, the difference was statistically significant (t = -7.634, P < 0.01) . While the latency and intensity of turning to lesion side in HSC-Can were larger than turn to normal side in HSC-Cup, and the difference detected no statistically significant difference (t = 1.554 and 0.305, P > 0.05).
CONCLUSIONSThe induced nystagmus intensity of head to two sides in roll tests for HSC-BPPV both follow Ewald's law, and the ratio between stronger and weaker are both 2: 1. These nystagmus parameters of VNG in roll tests are an objective guideline for BPPV diagnosis.

Objective:To evaluate the clinical efficacy of Bazheng Powder combined with Traditional Chinese Medicine (TCM) fumigation in the treatment of refractory urinary tract infection patients with Yin deficiency damp-heat syndrome.Methods:Randomized controlled trial design. Ninety-seven patients with Yin deficiency and damp-heat syndrome of refractory urinary tract infection in our hospital from April 2021 to May 2022 were selected as observation objects, and were divided into observation group (49 cases) and control group (48 cases) by random number table method. The control group was treated with antibiotics, and the observation group was treated with Bazheng powder plus or minus plus TCM fumigation on the basis of control group. Both groups were treated for 14 days. TCM syndrome score was performed before and after treatment. Test tube method was used to measure WBC, urine routine nitrite was used to measure urinary bacteria count, and the time to return to normal urine routine, symptom remission time and symptom disappearance time were recorded. Adverse reactions were recorded and clinical efficacy was evaluated.Results:The total effective rate was 95.92% (47/49) in the observation group and 81.25% (39/48) in the control group, and the difference between the two groups was statistically significant ( χ2=5.19, P=0.022). After treatment, TCM syndrome score of observation group was significantly lower than that of the control group ( t=13.18, P<0.01), WBC and urinary bacteria count were significantly lower than those in the control group ( t values were 19.77 and 22.99, P<0.01). The time of urine routine recovery, symptom remission and symptom disappearance in the observation group were significantly faster than those in the control group ( t values were 23.61, 9.80, 7.34, P<0.01). During the treatment period, the incidence of adverse reactions was 8.33% (4/48) in the control group, and no adverse reactions occurred in the observation group, the difference between the two groups was statistically significant ( χ2=4.26, P=0.039). Conclusion:The addition and reduction of Bazheng Powder combined with TCM fumigation can improve the clinical symptoms and clinical efficacy of patients with Yin deficiency damp-heat syndrome of refractory urinary tract infection, and no adverse reactions occurred.
