There are many causes of postpartum hemorrhage in lying-in women.The authors retrospectively analyzed the clinical data of 40 cases of uterine inertia-induced postpartum hemorrhage,investigated its causes,and proposed that for different cases midwives should take different preventive measures,such as psychological persuasion,childbirth guidance,anticipation,prediction,and pretreatment,so as to reduce the incidence of uterine inertia-induced postpartum hemorrhage.

Objective To study the clinical findings and audiological characteristics of auditory neuropathy. Methods Clinical findings, pure tone threshold, acoustic impedance audiometry, speech audiometry, auditory brainstem response (ABR) and distortion product otoacoustic emission( DPOAE) were analyzed in 23 cases of auditory neuropathy. Results The patients were predominantly youngster, female more than male. Pure tone audiometry revealed mainly binaural symmetric upward - sloping audiogram with mild and moderate hearing loss at low frequencies. Speech discrimination score was obviously reduced, which was disproportionately to the pure tone threshold. Ipsilateral and contralateral stapedial reflex were absent. ABR was severely abnor- mal. DPOAIE was normal or nearly normal. Conclusion Clinical findings and systemic audiometry revealed the main characteristics of auditory neuropathy, which could be used not only for the understanding, but also for the diagnosis of this disease.

Objective To evaluate the feasibility and efficacy of percutaneous intratumor injection of gene-immunotherapy combined with capacitive radio-frequency hyperthermia treatment for advanced lung carcinoma under CT guided.Methods Thirty-one unresectable peripheric lung carcinomas(29 men and 2 women,10 squamous carcinomas,15 denocarcinoma and 6 alveolus carcinomas) in clinical Ⅲ~Ⅳ stage were undergone percutaneous intrastumor injection of H101 and ⅠL~Ⅱ under CT guided,and repeated at 8,29,35,57 and 64 d respectively as one course.During interventional therapy,radio-frequency hyperthermia carried out twice one week,totally 12 times per-patient.After one course 4 weeks later,the blood TSGF levels and CT changes of the tumors were observed.Results The short period effect included:CR in 0 case,PR in 22 cases,NC in 6 cases and PD in 3 cases,the total short-term efficacy rate was 71 percent(22/31).Significant statistical difference was found in the positive rate and quantitative level of the blood TSGF after on cycle(P

0.05).The volumes of PBSC collected each time in the 3 groups were about 60 ml,and there were(3.67—10.25)?1010 erythrocytes per pack in the ABO major incompatible group,and 22—38 ml of plasma in ABO minor incompatible component.All the PBSC were infused to recipients without the removal of erythrocytes or plasma,and no haemolytic reaction was observed in any recipients and all their hematopoietic functions were re-established.Conclusion Enough PBSC can be harvested by using CS-3000 Plus blood cell separator from ABO incompatible allogeneic donors.By modification of separator parameters,the number of erythrocytes in the collects can be reduced.The collected PBSC can be safely infused into the blood group incompatible recipients without removal of erythrocytes or plasma.

Objective To explore the characte ristics of pure tone threshold (PTT) in auditory neuropathy. Methods The results of PTT audiometry were analysed in 48 patients with auditory neuropathy and compared with that of cochlear deafness. Results PTT audiograms in auditory neuropathy group r evealed curves including ascending slope, peak, spoon, letter W, lain letter S, flat, gentle slope. Binaural symmetric PTT audiograms were seen in 38 cases and asymmetric in 10 cases. The auditory threshold in auditory neuropathy showed a e levated range from mild to moderate degrees. Elevated degrees of auditory thresh old in left and right ears were consistent. The elevations of low-frequency audi tory threshold or in the main feature of low-frequency auditory threshold were 9 3.75% (90/96 ears) in the PTT audiograms. Conclusion The elevations of biauricular symmetric and ba sic symmetric low-frequency auditory threshold or in the main feature of low-fre quency auditory threshold were important characteristics of auditory neuropathy.

For the purpose of studying the diagnostic significance of the traumatic perforation of the tympanic membrane by the otologic endoscopy and video tape recording, one hundred and fourteen patients 117 ears, with ear drum injury caused by the head and facial trauma were examined and analyzed by using the Hopkin modle mult angle otologic endoscopy and the video tape recorder. The results showed that the traumatic perforation of te tympanic membrane were found in all four quadrants of the membrane,61 91% of the perforation located in the anteriorinferior quadrant,of the tense part of the membrane. The shapes of the perforation were spindle,triangular,slit, irregular and lune. The nontraumatic perforation of the tympanic membrane often located in the center or the margin of the membrane and were round or oval in shape. The otologic endoscopy and video tape recording can display the morphologic features of the traumatic and nontraumatic perforations of the tympanic membrane objectively and provide reliable diagnostic and investitgative method for the forensic practice.

Objective To study the effect of different doses of atorvastatin in the treatment of coronary heart disease with chronic heart failure. Methods 100 patients with chronic heart failure who were admitted to Ankang Hospital from April 2013 to April 2016 were selected and randomly divided into the experimental group and the control group with a total of 50 patients in each group. Two groups of patients were treated with conventional treatment, the control group was given 20 mg of calcium a day, the experimental group was given a daily dose of 40 mg of calcium. The therapeutic effects of the two groups were compared. Results After treatment, the left ventricular end diastolic diameter in the control group was significantly higher than that in the experimental group, the left ventricular ejection fraction and E/A were significantly lower than those in the experimental group, and the difference was statistically significant (P<0.05). Patients in the control group were significantly higher than those in the experimental group in the incidence of cardiac death and recurrence of heart failure (P<0.05). Before treatment, there was no significant difference between the experimental group and the control group in serum NT-proBNP, hs-CRP levels and 6MWT. After treatment, the serum levels of NT-proBNP, hs-CRP in the control group were significantly higher than those in the experimental group, 6MWT was significantly shorter than that in the experimental group, and the difference was statistically significant (proBNP) (P<0.05). Conclusion Compared with 20mg/d, 40mg/d dose atorvastatin in the treatment of coronary heart disease with chronic heart failure curative effect, low recurrence rate, high safety, worthy of further promotion in clinical.

Objective To assess the characteristics of abdominal hernia and summarize the therapeutic efficacy of mesh plug tension-free hernioplasty in elderly ventral hernia. Methods All 207 elderly patients with abdominal hernia who were admitted to our hospital during January 1999 to December 2001 and received the mesh plug tension-free hernioplasty were analyzed retrospectively. Results There were 405 patients receiving the mesh plug tension-free hernioplasty from 1999 to 2001, in whom 207 had elderly ventral hermia. Among the 207 elderly patients, 144 had inguinal oblique hernia, 38 direct hernia, 11 direct and indirect hernia, 6 sliding hernia, 6 incisional hernia, 1 femoral hernia, and 1 femoral and inguinal direct hernia. Postoperative complications were urinary retention(8 cases), hypoincisional hematoma(4), scrotal hydroceles(1), and incisional infection (1). One hundred eithty-seven patients were followed-up for 4-40 months and no recurrence was found. Conclusions The mesh plug tension-free hernioplasty is of advantages for elderly abdominal hernia, such as simpleness in performance and a good therapeutic effect. It is especially suitable for the elderly patients due to less trauma and low recurrence rate. It is also important to pay attention to the postoperative complications to the elderly.

Objective To investigate the significance and surgical skill for lymphadenectomy around common hepatic artery in gastric cancer.Methods Two hundred and fifty-seven cases with undergoing lymphadenectomy around common hepatic artery in gastric cancer between January 2001 and December 2006 were retrospectively reviewed.Experiences and understanding of dealing with this procedure in curative gastrectomy for gastric cancer were concluded.Results The number of dissected No.8 lymph node was 2.2?1.7,and the positive rate of No.8 lymph node was 30.35%.There were no lymphadenectomy related complications,such as anastomotic leakage,lymphatic fistula and postoperative hemorrhage in this series.Dissection around common hepatic artery lymph nodes along artery intrathecal space,division and ligation of left gastric vein at its root,and sufficient exposure of anatomic structures were important to dissection lymph nodes around the common hepatic artery.The exposure of anatomic structures included liberation of common hepatic artery by traction with the band,and the exposure of posterior side of pancreas by Kocher incision.Conclusion Being familiar with the anatomy around common hepatic artery,careful dissection,and attention to the surgical skill of lymphadenectomy are very important to improve the effectiveness of lymphadenectomy around common hepatic artery in gastric cancer.

Aim: To preliminarily investigate the antioxidant activity of the acidic exopolysaccharide(EPS-A) from cultivated Cordyceps sisnensis in vitro and in vivo. Methods: PC12 cells were injured by H_2O_2 after the cells were treated with different doses of EPS-A for 6 h, and then the levels of malondialdelyde( MDA) and superoxide dis-mutase (SOD) in PC12 cells were determined. H22 cells were inoculated into the right oxter of each mouse after ICR mice were treated with EPS-A for 7 days, and tumor-bearing mice were treated with EPS-A for 7 days. MDA level and SOD activity in liver, brain and serum were assayed, and tumor weight of each mouse was measured as well. Results: EPS-A significantly decreased the production of MDA and increased SOD activity in H_2O_2-injured PC12 cells. Moreover, EPS-A inhibited H22 tumor growth in mice, in which the level of MDA in liver and brain was reduced, and SOD activity in liver, brain and serum was enhanced. Conclusion: EPS-A exhibited antioxidant activity in cell cultures and mice.
