Objective To study the clinical features of invasive pulmonary aspergillosis (IPA) with chronic obstructive pulmonary diseases (COPD),so as to provide evidence for early diagnosis and treatment.Methods A retrospective analysis was made upon clinical data,diagnosis,treatment and prognosis of 53 patients with IPA and COPD admitted between January 2005 and February 2011 collected in a respiratory unit of the Second Xiangya Hospital Affiliated Central South University.Results There were 53 cases of diagnosed as IPA with COPD,with history of using broad-spectrum antibiotics.And there were 43 cases using steroids more than 2 weeks,51 with obvious breathlessness,and 20 with fever.Early stage didn't present characteristical changes on CT scan.However,after disease progression,32 cases had maculas shadows and nonspecific consolidations in bilateral lung,14 with solitary or multiple nodules,4 with solitary or multiple air crescent sign,and 2 with halo sign.Four patients of COPD with IPA underwent bronchoscopy examination.In fungi pathogeny,sputum positive rate and galactomannan positive rate were 56.6％ and 52.8％,respectively.A total of 53 cases received antifungal treatment.Among 37 cases which underwent mechanical ventilation,24 received noninvasive ventilation and 13 received invasive ventilation.There were 33 cases which were improved and cured,and 20 cases which had no relief after half-a-month treatment or withdrew treatment.Among them,13 cases died because of multiple-organ failure (5/15) or acute renal failure (8/15).Conclusions Early suspected diagnosis,timely examination in allusion to IPA,actively searching for etiological and imaging evidences,early established diagnosis and antifungal treatment would improve prognosis of patients with COPD combined IPA who have history of high doses of cortieosteroids,obvious breathlessness and non-response to antibiotics.

Objective: This present study is to investigate the biochemical adaptations in the related brain regions of the mesolimbic dopamine system, such as the ventral tegrnental area (VTA), nucleus accumbens (Nac), amygdale (Amy), prefrontal cortex (PFC) , substantia nigra (SN) and caudateputamen (Cpu) in response to heroin self-administration in rats and observe the effect of electroacupuncture on them. Methods: 2hirty rats were trained by nose-poking response to establish stable intravenous heroin self-administration within 14 days, and then divided randomly into model group (group B) including 6 rats, withdrawal group which were withdrawn from heroin for 1 week (group C, n = 6) and for 2 weeks (group D, n= 6), during which time they only lived in their individual home cages,and electro-acupuncture group which were also withdrawn from heroin for 1 week (group E, n= 6) and for 2 weeks (group F, n= 6), during which time they were given electro-acupuncture treatment for 20 min daily and then returned to their individual home cages; in the meantime, another 6 rats were trained by nose-poking response with saline for 14 days as control (group A); Then the levels of tyrosine hydroxylase (TH) and glial fibrillary acidic protein (GFAP) in VTA, Nac, Amy, PFC, SN, Cpu were detected with immunohistochemistry method. Results: The leveks of TH and GFAP in VTA of the heroin self-administrating rats were obviously increased, and the levels of TH and GFAP in Nac were also decreased, and these changes were not found in SN, Cpu, Amy and PFC; Electro-acupuncture could promote the up-regulation of TH and GFAP in VTA and down-regulation of TH and GFAP in Nac to return to the normal level. Conclusions: The chronic heroin self-administration produced some biochemical adaptations in the rdated brain regions of the mesolimbic dopamine system and electroacupuncture could promote the repair of the injured DA neurons in VTA of heroin addicted rats and their functional recovery.

Objective To investigate the role of serotonin transporter (SERT) in pathogenesis of abdominal pain in irritable bowel syndrome (IBS). Methods Neonatal SD rats were divided into control group and IBS abdominal pain model group which was established by colorectal distension.The colon, nucleus raphes dorsalis (NRD) and prefrontal cortex (FC) tissues were harvested when all rats grew into adults. Expressions of SERT and 5-HT were determined by real-time PCR and immunohistochemistry. Results The expression of SERT mRNA in colon, NRD and FC tissues in model and control group were 13.95±2.05 vs 8.65±1.33, 52.69±22.59 vs 13.82±5.71 and0.48±0.17 vs 0.17±0.14, respectively, with significant differences (all P values ＜0.05). The protein expression of SERT in colon and NRD,but not FC tissues,decreased in model group compared with control group (13.19±3.82 vs 21.35±4.49,2.47±0.44 vs 4.55±0.92, respectively, P＜0.05).Meanwhile, in comparison with control group, the expression of 5-HT in colon was significantly increased in model group (5.56±0.48 vs 2.68±0.22), but decreased in NRD and FC tissues (3.75±0.43 vs 7.46±0.72, 5.07 ± 0.80 vs 7.97 ±1.10, respectively, P＜0.05). Conclusions Low expression of SERT in brain and colon may attribute to the pathogenesis of abdominal pain in IBS.

With the rapid development of genome sequencing technologies, a large amount of prokaryote genomes have been sequenced in recent years. To further investigate the models and functions of genomes, the algorithms for genome annotations based on the sequence and homology features have been widely implemented to newly sequenced genomes. However, gene annotations only using the genomic information are prone to errors, such as the incorrect N-terminals and pseudogenes. It is even harder to provide reasonable annotating results in the case of the poor genome sequencing results. The transcriptomics based on the technologies such as microarray and RNA-seq and the proteomics based on the MS/MS have been used widely to identify the gene products with high throughput and high sensitivity, providing the powerful tools for the verification and correction of annotated genome. Compared with transcriptomics, proteomics can generate the protein list for the expressed genes in the samples or cells without any confusion of the non-coding RNA, leading the proteogenomics an important basis for the genome annotations in prokaryotes. In this paper, we first described the traditional genome annotation algorithms and pointed out the shortcomings. Then we summarized the advantages of proteomics in the genome annotations and reviewed the progress of proteogenomics in prokaryotes. Finally we discussed the challenges and strategies in the data analyses and potential solutions for the developments of proteogenomics.

Objective: This present study is to establish a rat model of intravenous heroin self-administration and observe the effect of electro-acupuncture on the heroin-seeking behavior of the heroin self-administrating rat. Methods: Six Male Wistar rats were surgically implanted with an intra-jugular intravenous catheters under sodium pentobarbital anesthesia,following a minimum recovery of 7 days, the rats were trained by nose-poke response with one daily 4-hour session for 14 consecutive days to self administer heroin (50 μg /kg / per injection), the session ended after 25 infusions were earned or 4 hours had passed, whichever came first, the reinforcement schedule was fixed ratio 1 (FR1) that the rat received a heroin injection for each nose poke response. And then the rats were given electro-acupuncture treatment daily 30min prior to each session and then were trained with one daily 4-h session for 7 consecutive days. Results: Stable intravenous heroin self-administration behavior of rats was established after 7-8 days' drug training, electro-acupuncture given to the stable heroin self-administrating rat 30 min prior to each session could reduce the drug self-administration behavior, namely the total heroin intake in each session was reduced, especially the 1st hour heroin intake, the initiation of first nose-poke response in each session was relayed, and the haste heroin-seeking behavior also became slower. Conclusions: The above results suggested that the electro-acupuncture had better detoxification effect.

BACKGROUND:Intraarticular cocktail analgesic injection is a popular postoperative analgesia method and can effectively control postoperative pain and relieve side effects after total hip arthroplasty.
OBJECTIVE:To compare and assess the effectiveness and safety of intraarticular analgesic injection or intravenous injection of parecoxib after total hip arthroplasty.
METHODS:A total of 60 patients undergoing total hip arthroplasty were randomly assigned to:treatment group (intraarticular cocktail analgesic injection with morphine, bupivacaine, and compound betamethasone), and control group (intravenous injection of parecoxib). Al patients received tramadol hydrochloride at 24 hours after replacement. Analgesic consumption, visual analog scale at rest and during activity, range of motion, and postoperative complication of patients in each group were recorded.
RESULTS AND CONCLUSION:Intraarticular cocktail analgesic injection significantly reduced analgesic consumption. When comparing visual analog scale scores, rest pain scores were significantly less in the treatment group at 12, 24 and 48 hours after replacement than that in the control group (P<0.05). Scores on range of motion were significantly less in the treatment group at 24 and 36 hours than that in the control group (P<0.05). No significant differences in total complications were detectable between the treatment and control groups (P>0.05). Results suggested that intraarticular cocktail analgesic injection lessened analgesic consumption after replacement, relieved early pain after replacement, and contributed to early rehabilitation of patients. Moreover, no significant adverse reactions were visible.
