Background and purpose:Previous researches have shown that procalcitonin differentiates infec-tious from non-infectious fever and assesses the severity of infectious diseases. This study aimed to investigate the clin-ical value of procalcitonin in patients with chemotherapy-induced febrile neutropenia.Methods:A total of 147 patients with chemotherapy-induced febrile neutropenia admitted to intensive care unit from Jan. 2012 to Dec. 2014 were di-vided into infectious group and fever of unknown origin group according to clinical symptoms, signs and etiology. The infectious group was divided into sepsis, severe sepsis, and septic shock groups according to the severity of infection. The procalcitonin levels were compared between different groups.Results:A procalcitonin cut-off value>0.935 ng/mL provided a sensitivity of 90.0%, speciifcity of 90.0% and AUC=0.905. The procalcitonin level of the infectious group was signiifcantly higher than that of the fever of unknown origin group [1.805 (1.268-2.523) ng/mLvs 0.555 (0.398-0.818) ng/mL,P<0.001]. There is a signiifcant difference between the severe sepsis group and the sepsis group [13.885 (7.600-17.961) ng/mLvs 1.805 (1.268-2.563) ng/mL,P<0.001]. Compared with the severe sepsis group, the value of procalcitonin in the septic shock group was signiifcantly higher [23.800 (20.050-30.478) ng/mLvs 13.885 (4.955-19.133) ng/mL,P<0.001].Conclusion:Plasma procalcitonin is a useful marker for diagnosing neutropenia in patients with infection. Meanwhile, procalcitonin can be used to assess the severity of infection in patients with neutropenia.

To evaluate the prevalence of mosquito-borne viruses in Manshi and Ruili (Yunnan Province, China), we collected 2 149 mosquitoes (17 species) in August 2010. Virus isolation was undertaken by the cul- ture of baby hamster kidney cells (BHK-21 cells). Two virus-like isolates were obtained: DHL10M117 was isolated from collected in Mangshi; DHL10M110 was obtained from Anopheles vagus collected in Rui- li. Both isolates caused cytopathic effects,illness and death in suckling mice inoculated with these isolates via the intracerebral route. Two positive amplicons, 702-bp from the S segment and 456-bp from the M segment,were obtained using reverse transcription-polymerase chain reaction using primers specific for the Akabane virus (AKV). Phylogenetic analysis suggested that these two virus stains had a distant relation- ship with AKVs from Kenya and Australia,but were genetically close to those from Japan,South Korea, and Taiwan. However,they were separate from other Asian strains and grouped into a small branch. The highest nucleotide and amino-acid sequence identity of the S segment was found with the CY-77 strain from Taiwan (96.6% and 99.6% for DHL10M117 and 96.7% and 100% for DHL10M110,respectively). Com- parison of the M segment showed they shared the highest amino acid identity with CY-77 (99.6% and 100%, respectively), whereas the highest nucleotide identity was found with the Iriki strain from Japan (99.6% and 100%, respectively). Compared with the MP496 strain from Kenya,they displayed lower lev- els of sequence homology, at 69.7% and 70.0% for nucleotide sequences of the two loci,and 91. 0% for a- mino acids. Our results identified that DHL10M117 and DHL10M110 were strains of AKV,and provided molecular biological evidence for the existence of AKV in Yunnan Province. These AKV strains that are circulating in Yunnan Province share a close genetic relationship with strains from the rest of Asia. Culex tritaeniorhynchus and Anopheles vagus may serve as transmission vectors.

Objective To observe the effect of bilateral movement training on upper extremities dysfunction in stroke patients in convalescent phase. Methods 52 patients with hemiplegia were randomly divided into treatment group (n=26) and control group (n=26). The treatment group accepted bilateral upper extremities movement training, and the control group accepted routine neurodevelopment training mainly with affected upper extremities, for 6 weeks. They were assessed with Fugl-Meyer Assessment upper-extremity section (FMA-UE) and modified Barthel Index (MBI) before and after treatment. Results The FMA-UE and MBI scores improved in both groups after treatment (P<0.01), and improved more in the treatment group than in the control group (P<0.001). Conclusion Bilateral movement training may improve upper extremity function and activities of daily living more effectively for stroke patients in convalescent phase.

OBJECTIVETo investigate the characteristics of inhibitory and activating receptor expressions on natural killer (NK) cells in HIV/HCV co-infected patients.

METHODSNumbers, frequencies and expressions of activating and inhibitory receptors of NK cells were measured with flow cytometry (FCS) from HIV/HCV co-infected group (n = 24), HCV mono-infected group (n = 34), HIV mono-infected group (n = 21) and healthy control group (HC, n = 20), then analysis and compare were performed among those groups.

RESULTSThe NK cell absolute counts in HIV/HCV group were significantly lower than those in other three groups. The NKP30 and NKP46 frequencies on NK cells in HIV/HCV, HIV and HCV groups were all significantly lower than those in HC group, but there were no significant differences of NKP30 among former three groups; and NKP46 frequencies in HIV/HCV and HIV groups were lower than those in HCV group, but there were no significant differences between former two groups. The NKG2A frequencies in HIV/HCV and HCV groups were all higher than those in HIV and HC groups significantly, but the NKG2A frequencies in HIV group were lower than those in HC group; There were no significant differences of NKG2D, CD158a and CD158b among those four groups.

CONCLUSIONNK cell numbers and expressions of activiting receptors on NK cells obviously decreased in HIV/HCV co-infected patients, but some inhibitory receptors expressions increased, even higher than those of HIV mono-infected patients. NK cells impairments in HIV/HCV co-infection is more severe than HIV or HCV mono-infection.

OBJECTIVETo study the expression of apoptosis and their regulatory genes, Bcl-2, Bax in hemangioma and vascular malformations.

METHODSThe specimens were taken from 68 cases of strawberry hemangioma or vascular malformations and 11 cases of normal skin. The expression of Bcl-2, Bax and Ki-67 in endothelial cells were investigated by immunohistochemical S-P method. The apoptosis index (AI) in endothelial cells was investigated by TUNEL method.

RESULTSKi-67 was positive in all the proliferating strawberry hemangioma, negative in the other groups. The expression of Bax was significantly higher in strawberry hemangioma than in vascular malformations and normal skin (P < 0.01). Bcl-2 was negative in all groups. The AI in endothelial cells of strawberry hemangioma was significantly higher than that of vascular malformations and normal skin. There were no statistically significant differences between the proliferating and involution strawberry hemangioma. There were no statistically significant differences between various types of vascular malformations and normal skin. With the increasing of the expression of Bax in strawberry hemangioma, the AI increased.

CONCLUSIONThese findings clearly demonstrate a much higher apoptotic activity in strawberry hemangioma than in vascular malformations and normal skin and suggest that apoptosis might be a cause of spontaneous involution of strawberry hemangioma and might not be a cause of the pathogenesis of vascular malformation. Bcl-2, Bax might play an important regulatory role in apoptosis in endothelial cells of strawberry hemangioma.
