Objective To investigate the effect of different levels of positive pressure (PEEP) during one-lung ventilation on blood gas and hemodynamics in patients with thoracoscopic lung bullae resection surgery.Methods Seventy-eight patients undergoing thoracoscopic lung bullae resection surgery were divided into three groups by random number table method,26 cases in each:group Ⅰ was only given one-lung intermittent positive pressure ventilation (IPPV) after two-lung ventilation,group Ⅱ was given one-lung IPPV and PEEP 5 cmH2O (1 cmH2O =0.098 kPa) after two-lung ventilation,group Ⅲ was given one-lung IPPV and PEEP 10 cmH2O after two-lung ventilation.Blood gas and hemodynamics were recorded and compared in the supine position and lateral position two-lung ventilation,one lung ventilation 10 and 30 min among three groups.Results Oxygen saturation was maintained at 0.99-1.00 in three groups.pH value,base excess,arterial carbondioxide partial pressure (PaCO2) and HCO3-at each time point in three groups had no statistical significance (P ＞ 0.05).Arterial oxygen partial pressure (PaO2) in group Ⅱ and group Ⅲ at one-lung ventilation 10,30 min was significantly higher than that in group Ⅰ [(336.2 ± 113.2),(348.5 ± 109.7) mmHg (1 mmHg =0.133 kPa) vs.(285.0 ± 103.5) mmHg,(357.6 ± 104.0),(358.9 ±103.2) mmHg vs.(276.0 ± 107.2) mmHg] (P ＜0.05),but were within the normal range,there was no statistical difference between group Ⅱ and group Ⅲ (p ＞ 0.05).Heart rate,mean arterial pressure,left ventricular ejection time,systemic vascular resistance at each time point in three groups had no statistical significance (P ＞0.05).Stroke volume,cardiac output in group Ⅱ and group Ⅲ at one-lung ventilation 10,30 min were lower than those in supine position and lateral position two-lung ventilation and the same period in group Ⅰ (P ＜ 0.05),but were within the normal range,there were no statistical differences between group Ⅱ and group Ⅲ (p ＞ 0.05).Conclusions Two-lung ventilation after one-lung IPPV and PEEP 5 cmH2O in thoracoscopic lung bullae resection surgery can maintain satisfactory PaO2 and PaCO2,hemodynamic change is not obvious; PEEP 5 cmH2O compares with only IPPV can further improve PaO2,but PEEP 10 cmH20 can't further improve PaO2.

The therapeutic effect and mechanism of moxibustion in the treatment of Herpes Zoster were studied. It was found that the level of T lymphocyte subsets of the patients with Herpes Zoster was within the normal range before treatment, but slightly lower than in the health group. Th cells and NK cells were significantly decreased in the patients with Herpes Zoster as compared with those in the health group (P＜0. 05),suggesting the cellular immunity of the patients with Herpes Zoster was decreased. After treatment with moxibustion, the level of all the T lymphocyte subsets was increased, close to the normal. Among them the levels of Th cells and NK cells were significantly different from those before the treatment (P＜0. 05). The disappearance of exanthema and relief of neuralgia in the patients was also quicker than in the controls (P＜0. 01). It was indicated that moxibustion had a good effect in the treatment of Herpes Zoster, which was contributed to the enhancement of the body antiviral ability by the improvement of immunity, especially the cellular immunity.

Objective To study the role of insulin-like growth factor 2 (IGF- Ⅱ ) in the proliferation and degeneration of hemangiomas. Methods The expression of IGF- Ⅱ and Ki-67 was detected with SP im-munohistochemical method in 52 specimens of hemangiomas, 27 of vascular malformation and 5 of normal skin. The expression of IGF-Ⅱ mRNA was examined by reverse transcription polymerase chain reaction (RT-PCR) in specimens from 9 cases of hemangiomas and 5 of vascular malformation. Results The labelling indexes (LI) of IGF- Ⅱ and Ki-67 and the expression of IGF- Ⅱ mRNA were significantly higher in heman gioma than those in vascular malformation and normal skin (P

Objective To explore the principles and methods of surgcal treatment for acute neoplastic colorectal obstruction.Methods The clinical data of 103 patients diagnosed as acute neoplastic colorectal obstruction were analyzed retrospectively.Results In this group,80 cases underwent emergency surgical treatment,(among) which,25 cases of carcinoma of right colon underwent primary resection and anastomosis;in 45 cases of carcinoma of left colon,primary resection and anastomosis was performed in 37 cases;and emergent(operations) were performed in 10 cases of rectal cancer.23 cases received non-emergency surgery.(Anastomotic) fistula occurred in 3 patients,pulmonary infection in 2 patients,pelvic cavity infection in 1(patient),1 patient died and the rest recovered well and were discharged.Conclusions The initial treatment for acute neoplastic colorectal obstruction should be non-surgcal treatment for 1~3d to make non-emergency surgical treatment more possible.If indications are properly selected,primary tumor resection and anastomosis is safe.For patients with severe contamination of abdominal cavity and bowel perforation, primary tumor(resection) should be performed if possible.

Objective To investigate the influence of a catastrophic event to the mental health of servicemen,and to observe the effect of mental intervention and drug treatment for them after experiencing a catastrophic flood attack.Methods 57 servicemen survived a catastrophic flood attack were regarded as the disaster group,and 70 others who were not involved in the flood disaster were regarded as the control group.The service men of the two groups were subjected to investigation with Chinese Military Mental Health Scale(CMMHS),and corresponding mental intervention or medication was given to those who had experienced mental disorders.Results The disaster resulted in different degrees of somatic trauma and various mental disorders including instability of emotion,mental depression,grievance,nervous tension,sensation of fear,sleep disorder and apprehensions.The influential factor scores of CMMHS,including compulsive neurosis,anxiety,depression,fear,psychosis,somatization,interpersonal sensitiveness,and total score were much higher in disaster group than that in control group,and that of norm of Chinese servicemen,while the neurasthenia factor score in disaster group showed no significant difference with that in control group and that of normal Chinese servicemen.The main influential factors to changes in mental health of the servicemen were witness of someone washed away by the flood,and participation in identifying corpses.Conclusion The mental health of servicemen who experienced a catastrophic flood disaster was harmed in various degrees,and medication or mental intervention appeared to be of value.

Objective To investigate the causes, prevention and treatment of recurrent laryngeal nerve (RLN) injury during operation in patients with thyroid cancer. Methods Clinical data of 192 patients undergone thyroidectomy operation were reviewed. Results RLN was exposed during operation in 192 patients. There were 3 cases of RLN injury, then RLN anastomosis was happened immediately during operation. It was significantiy improved in pronunciation after operation. 2 ～ 3 d after surgery, transitory hoarseness was observed in 3 patients. Unilateral RLN resection performed in 1 case with cancer involving RLN. Conclusions There were some causes of RLN injury. Exposure of RLN selectively,delicate operation and thyroid gland surgery specialist were the key point for prevention of the injury of RLN. Once RLN injury occured ,repairing should be performed as soon as possible.

Objective To obtain an accurate and effective method for thalamus segmentation based on resting-state functional magnetic resonance imaging (fMRI).Methods Based on the fact that resting-state fMRI technique examined spatial synchronization of spontaneous fluctuations in blood oxygen level-dependent (BOLD) signals indirectly reflect the neuronal and synaptic activity,the in-thalamus BOLD signal correlations were calculated,and then the k-means clustering algorithm was applied to obtain functional connectivity-based thalamus segmentation.Results The thalamus was divided into seven regions.Voxels within the same region were highly correlated with each other.The segmentation result was similar to that divided by functional connectivity between thalamus and the cerebral cortex.Conclusions Resting-state fMRI could provide not only the functional connectivity network between cortical and subcortical brain regions,but also the functional characteristics of thalamus.Segmentation algorithm using only internal information of thalamus shows lower computational complexity and higher processing speed than that based on the functional connectivity between thalamus and the cerebral cortex.

To compare the effects of polysaccharide nucleic acid fraction of bacillus calmette guerin (BCG-PSN) and thymopeptides on T-lymphocytes of normal and immunosuppressed mice, CD4+ and CD8+ T-lymphocyte subsets of single nucleic cell in thymus, spleen and peripheral blood were detected successively by flow cytometry after application of BCG-PSN and thymopeptides. Meanwhile, CD4+/CD8+ ratio was also calculated. The results showed that both BCG-PSN and thymopeptides could decrease the proportion of CD4+ CD8+ T-lymphocyte subsets in the thymus, at the same time increase CD4+ T-lymphocyte, CD8+ T-lymphocyte proportion in the three tissues. The fluctuation in amplitude was greater in thymopeptides group than that in BCG-PSN group. It is concluded that acting location of thymopeptides is in thymus, its stimulating action is stronger than that of BCG-PSN, while BCG-PSN not only accelerates the differentiation in thymus, but also has some direct stimulation to peripheral CD4+ T-lymphocytes, and can maintain CD4+/CD8+ ratio within normal range. So, BCG-PSN is safer.
