Methods From December 2008 to December 2009, 69 patients with epilepsy and 35 healthy people were selected as the patients group and control group. All the selected ones underwent continuous performance test (CPT), Stroop test and dual task, respetviely, to assess their sustained attention, selected attention and divided attention. Results In CPT, the reaction time prolonged and the omission rate increased significantly in the patient group compared with those in the control group (Plt;0.05). In Stroop test, the reaction time in the patients group prolonged under incongruous condition, and error rate increased under incongruous, congruous and neutral conditions. The reaction time interfered effects and error interfered effects increased under incongruous and neutral conditions (Plt;0.05); the boxes crossed and right rate of digit strings decreased and decrement increased during dual task than single task in the patient group (Plt;0.05). Conclusion The sustained attention, selected attention and divided attention of patients with epilepsy are impaired.
Prostate disease is one of the most common urological disease. A large number of studies have shown that prostate disease is related to changes in the local microenvironment. Periodontitis is a chronic inflammatory disease characterized by the destruction of periodontal tissue caused by a variety of pathogenic microorganisms. Its pathogenesis may involve many factors. Periodontitis may have adverse effects on cardiovascular, respiratory, digestive and endocrine systems. Recent studies have found that chronic periodontitis is associated with the occurrence and development of benign prostatic hyperplasia and prostatitis, but the relationship is not clear. Therefore, further research is needed. This article elaborates on inflammation and benign prostatic hyperplasia and prostatitis, periodontitis and prostatitis, and periodontitis and benign prostatic hyperplasia, aiming to provide certain ideas for clinical research and diagnosis and treatment.
Objective To explore the relationship between the HBsAg positive patients suffering from hepatocellular carcinoma (HCC) and HBV DNA genotype. Methods By using PCR type-specific primers combined with sequencing of genotype, we analyzed the genotype of HBV DNA in the serum of 500 patients with positive HBsAg in our hospital. Among them, 150 cases suffered from HCC. Results Genotype B and C were both predominant genotypes in HBsAg positive patients. But in HCC group, the rate of genotype C was 65.33% （98/150）, which was significantly higher than that in non-HCC group (88/350, 25.14%), while genotype B, in contrast, was 28.67% （43/150） and 68.86% （241/350）， χ2=75.45， Plt;0.05. The distribution of HBV DNA genotype B or genotype C in different gender or different age groups were not statistically significantly different in cases of HCC (Pgt;0.05). Conclusion Genotype C of HBV DNA is more common in patients with HCC, and maybe there is relationship between genotype C and the occurrence of HCC.
ObjectiveTo evaluate the safety and efficacy of unconventional abdominal drainage after laparoscopic hepatectomy.MethodsThe clinicopathologic data of patients who underwent laparoscopic hepatectomy for liver tumors in the Mianyang Central Hospital from June to December 2019 and met the inclusion criteria were retrospectively collected. Based on whether drainage tube was placed in the abdominal cavity during operation, the patients were divided into non-catheterized group (without drainage tube) and catheterized group (with drainage tube). The intraoperative data and postoperative complications (e.g. intraabdominal hemorrhage, bile leakage, abdominal infection, and liver failure) were compared between the two groups. Then, the intraoperative data and postoperative conditions of liver cancer and non-liver cancer patients with or without abdominal drainage tube were compared and analyzed.ResultsA total of 117 eligible patients were included in the study. The non-catheterized group had 59 patients and the catheterized group had 58 patients. The patients with liver cancer had 84 patients (44 non-catheterized patients and 40 catheterized patients) and the patients without liver cancer had 33 patients (15 non-catheterized patients and 18 catheterized patients). ① On the whole, the groups were comparable in the baseline data between the non-catheterized group and the catheterized group, such as gender, age, HBV infection, body mass index, hepatic function index, liver stiffness value, disease category, etc. (P>0.05). Compared with the catheterized group, the non-catheterized group had earlier off-bed activities and earlier flatus time (P<0.001), and shorter postoperative hospital stay (P=0.030). However, no statistically significant differences were found in other indicators between the two groups (P>0.05). ② Whether the patients had liver cancer or not, the non-catheterized patients still had earlier off-bed activities and earlier flatus time as compared with the catheterized patients (P<0.001). Among the patients with liver cancer, no difference was found in postoperative hospital stay. However, among the patients without liver cancer, the non-catheterized patients had shorter postoperative hospital stay than the catheterized patients (P=0.042). No statistically significant differences were found in other indicators between the catheterized patients and non-catheterized patients (P>0.05).ConclusionFor technologically skilled laparoscopic hepatectomy center, selectively not placing peritoneal drainage tube after surgery might better promote the health of patients.
ObjectiveTo investigate the prevention and control measures and procedures for surgical operation safety during the outbreak of new coronavirus pneumonia.MethodsAfter interpreting the diagnosis and treatment plan of new coronavirus pneumonia, the prevention and control plan of new coronavirus pneumonia, and the technical guidelines for prevention and control of new coronavirus pneumonia infection in medical institutions, we formulated and improved the prevention and control measures and procedures for surgical safety in our hospital.ResultsA total of 567 patients were operated in our hospital from January 22, 2020 to February 10, 2020, including 501 were operated in the surgical center and 66 were operated in the interventional center. Among all the cases, there were 303 emergency operation and 264 scheduled or limited operation. In the emergency operation, the top three were 130 cases of caesarean section (42.9%), 63 cases of abdominal digestive system operation (20.8%) and 31 cases of skull operation (10.2%). In the scheduled or limited operation, the top four were 65 cases of benign diseases of the eye (24.6%), 57 cases of tumor (21.6%), 53 cases of orthopedic surgery (20.1%), and 25 cases of coronary angiography (9.4%). All the patients were successfully completed the operation and recovered well after the operation. No serious surgical complications or infection-related complications occurred.ConclusionDuring the outbreak of new coronavirus pneumonia, surgery and epidemic prevention and control can be carried out by adjusting and optimizing measures and procedures.
【Abstract】Objective To study the clinical application of laparoscopic operation. Methods The clinical findings from 13 840 cases of laparoscopic surgery in this hospital from 1992 to 2005 were reviewed retrospectively.Results Laparoscopic operation were performed successfully in 13 653（98.6%）,187 cases were transferred to open operation. Complications were occurred in 115 cases, including common bile duct injury in 3 cases. Combined treatment with laparoscope and endoscope were performed in 162 cases. Eleven thousand three hundred and fiftytwo patients had been succeeded in followup survey. Over 90.0 percent of patients recovered smoothly. Conclusion Laparoscopic operation may be applied in a more extensive scope. The major complications can be reduced by strict procedures of laparoscopic operation. The combined treatment of laparoscope and endoscope should be further studied and widely used.
Objective To explore the contribution of obstructive sleep apnea hypopnea syndrome(OSAHS) in the variations of blood pressure in the evening to morning and possible mechanisms.Methods In Sleep and Breathing Disorders Centre，from September 2003 to September 2007，adult patients whose Epworth sleeping scoregt;9 were undergone polysomnography(PSG) and divided into 4 groups according to apnea hyponea index(AHI).The levels of blood pressure were monitored and compared between evening and morning.Correlations between PSG indexes and variations of the systolic blood pressure(SBP) and diastolic blood pressure(DBP) were analyzed in OSAHS patients.Results 1 528 patients were enrolled in this study.There was no significant difference between the evening and morning blood pressure in the non-OSAHS group(AHIlt;5，n=172)，whereas DBP rised about 1.73 mm Hg in the mild OSAHS group(AHI≤20，n=435)，SBP and DBP rised about 3.52 and 3.71 mm Hg respectively in the moderate OSAHS group(AHI≤40，n=307)，and SBP and DBP rised about 3.72 and 4.22 mm Hg respectively in the severe OSAHS group(AHIgt;40，n=614).The variation of SBP during the night correlated positively with the arousal index in the mild OSAHS group（r=0.25，Plt;0.05），but with the body mass index (BMI) in the moderate OSAHS group（r=0.25，Plt;0.05）.In the severe OSAHS group，the variation of SBP during the night correlated positively with BMI and the longest apnea time (LA)（r=0.26，0.25，both Plt;0.05），the variation of DBP during the night correlated positively with AHI and mean apnea duration(MA)（r=0.22，0.17，both Plt;0.05），and the variation of mean arterial pressure during the night correlated positively with AHI and MA（r=0.25，0.20，both Plt;0.05）.Conclusion OSAHS may induce mild rises of the blood pressure at night.The relevant factors that influence the blood pressure are different in different severity of the OSAHS.
Objective To investigate the distribution and antibiotic resistance of pathogens isolated fromlower respiratory tract in mechanically ventilated patients with acute exacerbation of chronic obstructive pulmonary disease ( AECOPD) . Methods The patients with AECOPD, who were hospitalized in RICU from January 2008 to November 2009, were divided into a community infection group and a nosocomial infection group. Lower respiratory tract isolates were collected by bronchoscopic protected specimen brush for bacterial identification and susceptibility test. Results 134 cases were enrolled in the study, with 75 cases in thecommunity infection group and 59 cases in the nosocomial infection group. The positive detection rate in the nosocomial infection group was significantly higher than that in the community infection group [ 81. 4%( 48/59) vs. 54. 7% ( 41/75) ] . In the community infection group, 49 strains were isolated, in which gramnegativebacteria, gram-positive bacteria, and fungi accounted for 55. 1% , 28. 6% , and 16. 3% , respectively.In the nosocomial infection group, 55 strains were isolated, in which gram-negative bacteria, gram-positive bacteria, and fungi accounted for 61. 8% , 21. 8% , and 16. 4%, respectively. There was no significant difference in the microbial distribution between the two groups ( P gt; 0. 05) . The detection rate of ESBLs producing strains in the nosocomial infection group was significantly higher than that in the community infection group ( 58. 8% vs. 37% ) . The resistance rates in the nosocomial groups were higher than those in the community infection group. Conclusions Antibiotic resistance is serious in mechanically ventilated patients with AECOPD, especially in the nosocomial infection patients. The increased fungi infection and drug resistance warrant clinicians to pay more attention to rational use of antibiotics, and take effective control measures.
【Abstract】 Objective To study the effects of obstructive sleep apnea hypopnea syndrome ( OSAHS) on blood pressure variations, and explore the possible mechanism. Methods 84 adult patients ( mean age 50. 1 ±14. 8 years, male /female 67 /17) were recruited for polysomnography ( PSG) and ambulatory blood pressure monitoring. Four groups were identified based on apnea hyponea index ( AHI) ,ie. non-OSAHS group ( n=9) ,mild group ( n=19) , moderate group ( n=23) , and severe group ( n =33) .The blood pressure levels were compared among the four groups. Correlations between PSG indexes,variations of systolic blood pressure ( SBP) and diastolic blood pressure ( DBP) were analyzed. Results Inter-group blood pressure comparison showed significant differences in SBP and DBP( P lt;0. 05) , except forthe mild and the moderate OSAHS patients. As compared with the non-OSAHS patients, SBP for those with severe OSAHS was about 15 mm Hg higher, and DBP 10 mm Hg higher. Observation on SBP non-dipping rate indicated that, except for the mild and the moderate OSAHS patients where no significant differences were found, SBP non-dipping rate increased with the severity of OSAHS( the rates were 78. 3%, 57. 1% ,54. 5%, and 32. 6% , respectively for the four groups) , whereas DBP non-dipping rate significantly increased in the severe OSAHS patients( 54. 3% ) ( P lt;0. 05) . For the mild OSAHS patients, blood pressure was found to be correlated positively with the body mass index ( correlation coefficient for day time SBP was 0. 26, and for DBP was 0. 22) , the arousal index ( correlation coefficient for day time SBP was 0. 25, and for DBP was 0. 17) , and heart rate variation ( correlation coefficient for night time SBP was 0. 18, and for DBP was 0. 17) . For the moderate OSAHS patients, a positive correlation was also found between blood pressure and AHI ( correlation coefficient for day time SBP was 0. 31, and for DBP was 0. 22, correlation coefficient fornight time SBP was 0. 26) , and between blood pressure and the longest hypopnea time during sleep ( LH) ( correlation coefficient for night time DBP was 0. 2) . For the severe OSAHS patients, blood pressure was correlated positively with apnea index ( AI) ( correlation coefficient for day time SBP was 0. 61, and for DBP was 0. 5, correlation coefficient for night time SBP was 0. 57 and for night time DBP was 0. 48) . Conclusions OSAHS has ber impact on SBP than on DBP. DBP hypertension and SBP non-dipping are usually found in early OSAHS-affected patients. Factors affecting blood pressure differ with the severity of the OSAHS.
Objective To evaluate the safety and tolerance of pegfilgrastin (PEG-G-CSF) in Chinese healthy volunteers. Methods Thirty healthy volunteers were randomly divided into five single-dose groups to receive PEG-G-CSF 15, 30, 50, 60 or 75μg/kg by hypodermic injection. The safety profile and tolerability were evaluated by observing symptoms, vital signs, laboratory tests and electro cardiogram. Results No serious adverse event was reported for any volunteer. Transient dizziness occurred in one person in the 50 μg/kg dose group, and mild dizziness and ostalgia was found in all six people in the 75μg/kg dose group, of whom one experienced transient fever and two experienced mild diarrhea. No clinically significant changes in laboratory tests and electrocardiogram were found during the follow-up period. Conclusions The maximum tolerated dose of PEG-G-CSF injection in Chinese healthy volunteers is 60 μg/kg. Doses below 60μg/kg can be well tolerated. The recommended dose for phase II clinical trials is 60 μg/kgone, one dose for each cycle of chemotherapy.
