Based on the lethal rate, positive and negative mutation rate, the optimal doses of UV, HNO2, UV + AO treating S. hygroscopicus NND-52-29 were determined. The mutant strain A19 that was obtained showed the derepres-sive property to glucose and the nigericin yield of A19 could be increased by 128%. When it was subcultured combined with natural screening, its stability was rather satisfied.

Objective To study the imaging features regarding perineural spread of tumor along the trigeminal nerve in malignant head and neck tumors, investigate its usefulness in improving diagnostic accuracy and palnning for clinical treatment. Methods Images in 9 patients with clinical or radiological findings suggestive of perineural spread along trigeminal nerve were retrospectively studied. Results Among the 9 patients, 6 were adenoid cystic carcinoma of the hard palate (n=3), maxillary sinus (n=1), parotid gland (n=1) and buccal space (n=1), respectively. Two were nasopharyngeal carcinoma and 1 was squamous carcinoma of the maxillary sinus. Enlargement and fat effacement of greater palatine foramen and pterygopalatine fossa distant from primary diseases were seen in all the 3 patients with adenoid cystic carcinoma of the hard palate and 1 with squamous carcinoma of maxillary sinus, furthermore, enlargement of foramen ovale and invasion of meckal cave was seen in 1 case. Erosion of infraorbital foramen and enlargement of the pterygopalatine fossa was seen in 1 patient with adenoid cystic carcinoma of maxillary sinus. Enlargement of pterygopalsatine fossa and foramen rotundum and invasion of the Meckal cave were seen in 1 patient with adenoid cystic carcinoma of buccal space. Perineural spread along auriculotemporal nerve and intracranial invasion through foramen ovale were seen in 1 patient with adenoid cystic carcinoma of parotid gland. Enhancement of mandibular nerve was seen in 2 patients with nasopharyngeal carcinoma. Conclusion Perineural tumor spread along trigeminal nerve can be seen in malignant head and neck tumors, and knowledge of the anatomy of trigeminal nerve and its surrounding structures is important for correct diagnosis.

Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

The diagnosis and treatment of prostate cancer are being improved due to the popularized screening of prostate specific antigen. Advanced prostate cancer, in spite of its response to androgen deprivation therapy, may finally develop into castration-resistant prostate cancer (CRPC) and shorten the overall survival of the patients. Many efforts have been made by worldwide researchers for new approaches to the management of CRPC, including new hormonal therapy, cytotoxic chemotherapy, immunotherapy, and bone metastasis-targeted therapy. This paper reviews the emerging agents undergoing clinical evaluation and drugs that have received approval for the treatment of CRPC in order to provide doctors and patients with more treatment options for CRPC and improve the overall survival rate and quality of life of the patients.

Objective To investigate the effect of perioperative pulmonary infection in elderly patients with mild to moderate chronic obstructive pulmonary disease (COPD) undergoing general anesthesia.Methods Forty elderly patients undergoing general anesthesia and abdominal surgery, 24 males, 16 females, aged 65-81 years, ASA physical status Ⅰ-Ⅲ, BMI 19-28 kg/m2, were randomly divided into two groups (n=20 each): protective ventilation group (group PV) and conventional ventilation group (group CV).Lung protective ventilation was received in group PV: intermittent positive pressure ventilation, tidal volume 6 ml/kg (ideal body weight), positive end expiratory pressure (PEEP) 5-10 cm H2O, alveolar recruitment maneuver every 30 minutes;conventional ventilation was received in group CV: intermittent positive pressure ventilation, tidal volume 10 ml/kg (ideal body weight), without using the PEEP and alveolar recruitment maneuver.Venous blood samples for interleukin 6 (IL-6) and interleukin-8 (IL-8) were taken at five different time points: before the anesthesia induction (T1), 2 h after mechanical ventilation (T2), at the end of operation (T3), 6 h (T4) and 24 h (T5) after operation.The clinical pulmonary infection score (CPIS) was recorded at before anesthesia, days 1, 3, 5 and 7 after surgery.The incidence of postoperative pulmonary inflammation was also recorded.Results There was no statistical difference in the two groups with respect to age, body mass index, ASA physical status, intraoperative volume of infusion, estimated blood loss, urine volume, mechanical ventilation time, operation method and IL-6, IL-8 levels at T1-T5.Compared with T1, the IL-6 and IL-8 levels in two groups at T2-T5 increased significantly (P<0.05).Compared that before anesthesia, CPIS in group CV on postoperative days 1, 3 and 5 increased significantly (P<0.05);compared with group CV, CPIS and the incidence of postoperative pulmonary inflammation in group PV reduced significantly on postoperative days 1, 3 and 5 (P<0.05).Conclusion Lung protective ventilation can not reduce perioperative IL-6, IL-8 levels in laparotomy elderly patients with COPD, but it can reduce the incidence of pulmonary inflammation and pulmonary infection within 5 postoperative days.

Objective To observe the abnormality of gray matter volume and density in patients undergoing postoperative delirium (POD).Methods Forty-seven cases of aged patients, 26 males and 21 females, aged 60-75 years, ASA physical status Ⅱ or Ⅲ, were selected.On the third day after operation, cognitive function estimation was performed.The patients were assigned into group POD and group C according to whether POD occurred and brain magnetic resonance imaging (MRI) scanning was implemented.The discrepancy in gray matter volume and density between the two groups were compared using voxel-based morphometry method (VBM).Correlation analysis was performed between the corresponding parameters in the regions where notable differences between the two groups existed and minimum mental state examination (MMSE) score were found.Results Global gray matter volume of group POD was notably lower than that of group C (P<0.01).Cerebrospinal fluid volume of group POD was significantly higher than that of group C (P<0.01).Gray matter volume of bilateral frontal gyrus and right parahippocampus was remarkably reduced in group POD (P<0.001).Gray matter density of bilateral hippocampus and right parahippocampus decreased significantly (P<0.001).Right parahippocampal gray matter volume was positively correlated with MMSE score in POD patients (P<0.05).Conclusion Structural abnormality in frontal regions, hippocampus and parahippocampus may play an important role in pathogenetic and developing process of POD.Gray matter volume in the right parahippocampus may be one of reference index for POD severity.
