Objective: To observe the efficacy of acupuncture combined with naloxone hydrochloride in the treatment of coma after surgery for cerebral hemorrhage and to explore its possible mechanism of action. Methods: Seventy-two patients were divided into a control group and an observation group according to the random number table method, with 36 cases in each group. The control group was treated with intravenous naloxone hydrochloride, and the observation group received additional acupuncture treatment. After 1 month of treatment, the awakening rate, Glasgow coma scale (GCS) score, cerebral edema volume, mean velocity (Vm) of the middle cerebral artery, and cerebrospinal fluid Caspase-3, and macrophage migration inhibitory factor (MIF) levels were compared between the two groups. Results: During the study, there were 2 cases of shedding in the control group and 34 remaining valid cases; 1 case of shedding in the observation group and 35 remaining valid cases. After treatment, the awakening rate was higher in the observation group than in the control group (P<0.05); the GCS score increased in both groups compared with that before treatment (P<0.05), and was higher in the observation group than in the control group (P<0.05); the volume of cerebral edema decreased in both groups (P<0.05), and was smaller in the observation group than in the control group (P<0.05); the middle cerebral artery Vm increased in both groups (P<0.05), and was higher in the observation group than in the control group (P<0.05); the cerebrospinal fluid Caspase-3 and MIF levels decreased significantly in both groups (P<0.05) and were lower in the observation group than in the control group (P<0.05). Conclusion: Acupuncture combined with naloxone hydrochloride for the treatment of coma after surgery for cerebral hemorrhage can promote patients' awakening, improve the degree of coma, reduce the volume of cerebral edema, and enhance cerebral blood flow velocity, producing a better effect than naloxone hydrochloride used alone; it may be related to its reduction of cerebrospinal fluid Caspase-3 and MIF levels.

Objective To investigate the differential diagnostic value of CT scan minimum attenuation values (minAVsCT) in adrenal adenomas and non-adenomas.Methods CT scan data of 89 cases of clinical and pathologically confirmed adrenal adenomas were subjected to retrospective analysis and compared with data of 46 cases involving 50 non-adenomas (25 metastases,20 pheochromocytomas,3 lymphomas,and 2 cortical carcinomas).The distributions of mean attenuation values (meanAVs) ￥ 10 Hu and minAVs ￥0 Hu and CT histogram analysis with ≥ 10％ negative pixels were observed in adrenal adenomas and non-adenomas,and the diagnostic sensitivity and specificity of these 3 methods for adenomas were calculated.Results The distributions of unenhanced meanAVs ￥ 10 Hu,minAVs ￥0 Hu,and CT histogram analysis with ≥ 10％ negative pixels among cases of adenoma and non-adenoma were 62.9％ (56/89) and 0％ (0/50) (x2=52.687,P=0.000),84.3％ (75/89) and 2％ (1/50) （x2=83.917,P=0.000),and 77.5％ (69/89) and 0％ (0/50) (x2=83.917,P=0.000),respectively.The respective diagnostic sensitivities,specificities,false negative rate (FNR),false positive rate (FPR),positive pre dictive value (PPV),negative predictive value (NPV) and accuracy of these 3 methods for adenomas were 62.9％vs 84.3％ vs 77.5％,100％ vs 98.0％ vs 100％,37.1％ vs 15.7％ vs 22.5％,0 vs 2％ vs 0,100％ vs 98.7％ vs 100％,60.2％ vs 77.8％ vs 71.4％,and 76.3％ vs 89.2％ vs 85.6％.Conclusion Although the specificity and PPV of minAVs≤0Hu is slightly less than meanAVs≤10Hu and CT histogram analysis with ≥ 10％ negative pixels,it exhibits the best sensitivity and accuracy with a simple operation,and is thus suitable for clinical application.

Objective: Identification of the genes specially expressed in tumor cell but not in normal cell is important for understanding the molecular mechanisms of carcinogencsis. This study will focus on identification of differentially expressed gene fragments in human stomach cancer. Methods: By using the new developing mRNA differential display (DD) technique, genes fragments differentially expressed in stomach cancer tissues from a patient and the adjacent normal tissues beyond the tumor mass were studied. Results: Two differentially displayed complementary DNA fragments from stomach cancer tissues, scgl and scg2 (stomach cancer-associated gene, scg), cofirmed by Northern Blot, were cloned and sequenced. The nucleotide length of scgl is 194 base pairs and that of scg2 is 343 base pairs. After searching against GenBank databases by BLASTN, neither scgl nor scg2 had significant homological gene sequences with the known genes. Conclusion: These results suggested scgl and scg2 might be complementary DNA fragments of novel genes expressed in stomach cancer tissues, but not in normal tissues and may play a role in the occurrence and development of stomach cancer. Further characterization of full-length of these two complementary DNA fragments will be continued.

Objective To compare the efficacy and safety of two kinds of homemade sirolimus-eluting stents (Firebird and Excel) for treatment of acute ST segment elevation myocardial infarction (STEMI) in patients who underwent percutaneous coronary intervention (PCI). Methods The 249 consecutive patients with STEMI who underwent PCI were randomly divided into two groups: Excel group (n=136) and Firebird group (n=113). They were followed up for 6-24 months, and coronary angiography was reviewed average 12 months later. The primary endpoints were major adverse cardiac events, including death, reinfarction and target vessel revascularization. The second endpoints included late luminal loss and restenosis 12 months after treatment. Results There were no significant differences in baseline data, coronary arterial lesion before operation, and immediateness condition after PCI between the two groups (all P＞0.05). Within follow-up, there were 2 (1.47%) death cases and 1 (0.88%) death case, 1 (0.74%) and 1 (0.88%) nonfatal myocardial infarction case, 2 (1.47%) and 2 (1.77%) target vessel revascularization cases in the two groups respectively (all P＞0.05). There were no significant differences in late luminal loss of in-stent and in-segment, the rates of in-stent restenosis, in-segment restenosis and stent thrombosis, the in-stent minimal lumen diameter and in-segment minimal lumen diameter between the two groups (all P＞0.05). Conclusions The two kinds of homemade sirolimus-eluting stents may have similar efficacy and safety in patients with STEMI treated with primary PCI.
