A 43-year-old man was diagnosed as massive left occipital lobe hemorrhage with the hematoma expanded into the entire ventricular system. On admission, he was in deep coma with clinical signs of brain herniation and a Glasgow Coma Scale (GCS) score of 4. Vascular malformations were highly suspected since he was young with no history of hypertension. Considering the life-threatening situation, open craniotomy and hematoma evacuation was proposed as the first therapeutic option, but this was refused by his family members for non-medical reasons. In order to save his life, stereotactic aspiration was suggested again and was accepted. UK at an aggressive dosage of 50 000 IU was administered during and after the surgical procedure for 5 days. One month later, this patient gained an excellent recovery with a Glasgow Outcome Scale (GOS) score of 5.

OBJECTIVE To explore the interventions for ventilator-associated pneumonia(VAP) caused by Acinetobacter baumannii by making investigation to the ICU patients on ventilators.METHODS Bacteria culture of bronchial discharge of patients on ventilators was conducted and followed by causation analysis of VAP caused by A.baumannii.RESULTS The prevalence of VAP caused by A.baumannii was 8.7%.The main reasons for VAP caused by A.baumannii were inappropriate use of antibiotics,long duration of mechanical assisted ventilation,contaminated ventilator and its accessories,unable to perform proper aseptic technique,and severity of the underlying illness.CONCLUSIONS For patients on ventilator,effective nursing interventions and sterilization and isolation techniques can reduce the infection and promote the treatment effects.

Objective To evaluate the indications and intraoperative management of nephron-spar- ing surgery (NSS) for renal cell carcinoma (RCC).Methods A total of 53 patients (32 men and 21 women;age range,21 -76 years) with unilateral RCC and a normal contralateral kidney underwent NSS.The disease course ranged from 1 week to 13 months.The unilateral RCCs were detected by B-uhrasonography. Partial nephrectomy was performed on 38 cases of polar RCC and wedge nephrectomy was performed on 15 cases of central RCC.Both renal vein and artery were blocked for 10 - 15 min,and unclamped for 1 -2 min if necessary.The resections were finished within 7 -21 min (mean,12 min).No inosine and regional hypo- thermia were used during operation.Absorbable hemostatic gauze and terylene flake were used to suture renal wound surface.After operation all patients were treated with interferon hypodermic injection of 5 000 000 U every other day for 3 months.Results The diagnosis of RCC with negative cutting margin was confirmed by pathological examination in all patients.The greatest dimension of the renal cancers were＜4 cm except for one of 6 cm.The clinical stage was T_1N_0M_0 in all patients.During the follow-up of 6 -48 months,all pa- tients were alive without recurrence and had normal renal function.Conclusions NSS can be rapidly per- formed for T_1 stage renal cancer＜4 cm or single clearly localized cancer＞4 cm in diameter.The follow-up results are satisfactory.

OBJECTIVE: To investigate the expression of hyperpolarization-activated cyclic nucleotide-gated cation channel 4 (HCN4) and connexin43 (Cx43) in the sinoatrial node of electric shock death. METHODS: As experimental group, 34 cases of electric shock death who had definite current mark evidence were selected from pathology department of Xuzhou Medical College from 2010 to 2013. As the control group, 20 cases of fatal severe craniocerebral injury in traffic accidents were chosen. The expressions of HCN4 and Cx43 in the sinoatrial node were observed by immunohistochemical technology. RESULTS: HCN4 positive cells expressed in the cell membrane and cytoplasm of the sinoatrial node. Cx43 positive cells expressed in the cell membrane and cytoplasm of T cells and myocardial cells. The expression of HCN4 was significantly higher than that of the control group (P < 0.05) and the expression of Cx43 was significantly lower than that of the control group (P < 0.05). CONCLUSION The changes of HCN4 and Cx43 expressions in the sinoatrial node illustrate electric shock death might be related to the abnormalities of cardiac electrophysiology and conduction.

OBJECTIVEThe expressions of caspase-1 and cytokines activated by caspase-1 are associated with the pathophysiology of many diseases for its proinflammatory and proapototic peculiarity. However its relationship to brain injury of developing rats following recurrent seizures has not yet been identified. This study aimed to investigate the role of caspase-1 and cytokines activated by caspase-1 in brain injury of developing rats following recurrent seizures.

METHODSA total of 96 postnatal 20 day Sprague-Dawley rats were randomly assigned into Control and Seizure groups. Seizures were induced in the Seizure group by flurothyl inhalation daily for six days. Brain tissues were sampled at 6 hrs, and at 1, 3, and 7 days after last seizure. The expressions of caspase-1, interleukin (IL)-18 and IL-1beta mRNA in the cerebral cortex were detected by RT-PCR. The water content of the brain and the pathological changes of cortex nerve cells were observed. Brain injury was evaluated using a semiquantitative neuropathological scoring system.

RESULTSThe levels of caspase-1 and IL-18 mRNA in the cerebral cortex of the Seizure group were obviously higher than those in the Control group at 6 hrs, and at 1, 3, and 7 days after seizure (P < 0.05 or P < 0.01). The expression of IL-1beta mRNA in the Seizure group exhibited a biphasic pattern: increased significantly at 6 hrs, and at 1 and 7 days post-seizure (P < 0.01), but was not significantly different from the Control group at 3 days post-seizure. Edema, degeneration and necrosis of nerve cells in cerebral cortex, accompanying by inflammatory cell infiltration and apoptosis of nerve cells, were observed under a light microscope in the Seizure group after recurrent seizures. The water content of the brain in the Seizure group increased significantly compared with that in the Control group at 6 hrs, and at 1 and 3 days after recurrent seizures (P < 0.01). The Seizure group had significantly higher neuropathological scores than the Control group at each time point (P < 0.01).

CONCLUSIONSCaspase-1 and cytokines activated by caspase-1 play an important role in the developing brain injury after recurrent seizures.

OBJECTIVETo explore the distribution characteristics of basic syndromes and its related factors in patients with chronic functional constipation (CFC).

METHODSThe complete data of 538 patients with CFC were collected and initial database was established with Epidata 3. 0. TCM syndrome typing was performed. The distribution characteristics of basic syndromes were analyzed using SPSS 17. 0 Software. The univariate and multivariate Logistic regression analyses were performed with SPSS 17. 0 Software to determine basic syndrome related factors such as age, engaged professionals, sleep quality, depression, mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation, and so on.

RESULTSThe TCM syndrome frequency of CFC patients was sequenced from high to low as qi deficiency syndrome (380 cases, 70.6%), qi stagnation syndrome (337 cases, 62.6%), blood deficiency syndrome (234 cases, 43.5%), yin deficiency syndrome (220 cases, 40.9%), yang deficiency syndrome (197 cases, 36.6%), and others(58 cases, 10. 8%) . Most patients were complicated with complex syndromes, and the most common complex syndromes were qi deficiency complicated qi stagnation syndrome (275 cases, 51.1%) and qi deficiency complicated blood deficiency syndrome (222 cases, 41.3%). Aging, work fatigue, and exercise conditions were main related factors for qi deficiency syndrome (P <0. 01, P <0. 05). Poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, defecation barriers constipation were main related factors for qi stagnation syndrome (P <0.01). Sleep quality and poor emotional (depression and anxiety tendencies) were main related factors for blood deficiency syndrome (P <0. 01, P < 0.05). Stimulating beverages were main related factor for yin deficiency syndrome (P <0.05). Engaged in mental work and slow transit constipation were main related factors for yang deficiency syndrome (P < 0. 01, P <0. 05).

CONCLUSIONSCFC is featured as complex syndromes. The most common complex syndromes were qi deficiency complicated qi stagnation syndrome and qi deficiency complicated blood deficiency syndrome. Basic syndrome related factors such as age, engaged professionals, sleep quality, poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation were associated with the distribution of CFC syndromes.
