To obtain the genome sequence of human bocavirus 2 (HBoV2), different regions of HBoV2 genome were amplified through PCR in fecal specimens which had been identified as single-positive for HBoV2 in 2010. A genome sequence of HBoV2 (HBoV2-NC, 5444 bp) was obtained after sequence assembly. The phylogenetic analysis showed that HBoV2-NC had the closest evolutionary relationship with HBoV2 Lanzhou strain. The predication of inverted terminal repeats of HBoV2-NC by DINAMelt showed that inverted terminal repeats were contained in HBoV2-NC 5' terminal, which had the typical stem-loop structure in other parvoviruses. Finally, some flanking sequences of HBoV2-NC were amplified by linker-PCR.

OBJECTIVETo investigate the effect of Qianlie Huichun capsule on the microstructure and ultranstructure of prostate glandular tissue in the model rat.
METHODHynertophy of prostate model rat was established by injecting testosterone to gelding male rats. After having been fed with Qianlie Huichun capsule for 30 days, the rats were killed and prostate tissues were resected for pathomorphological studies with microscope and electromicroscope, and the diameter of glandular lumer and the height of glandular epithelial cells were measured under the microspcope for different groups of rats.
RESULTIn the model groups, the glandular epithelial cells mutiplycated notably, showing stratified and pseudostratified cells that made the glandular lumer cramped. Under the electromicroscope, the glandular epithelial cells became high columnor and the rough endoreticulum extremely expanded. But in treatment groups, the change of the diameter of the glandular lumer and the height of the glandular epithelial cells were less remarkable than those in model groups. So the differerence between the model group and the treatment groups was remarkable (P < 0.01).
CONCLUSIONQianlie Huichun capsule can depress the glandular epithelialceu multiplication of prostate gland in model rats.

Objective To investigate the causations, management and prevention methods on the complications of hysteroscopic procedures. Methods Retrospective analysis of 36 cases with hysteroscopic complication, focusing on their characteristics and clinical management as well as prevention methods during the ten years from 1993 to 2004. Results Among 36 cases, 11 cases with uterine perforation and incomplete perforation, which happened during the complicated procedures, were treated by both laparoscopy and laparotomy. Five cases with heavy bleeding were encountered because of the deeply injury to the uterine wall and Foley catheter was inserted into uterine cavity and it stopped the bleeding successfully except in one case done by hysterectomy. Three cases with fluid overload syndrome were cured by using diuretic agent and saline infusion. There is no serious consequence in one case with air embolism due to prompt diagnosis and treatment. Four cases with postablation-sterilization syndrome were treated effectively by performing hysterectomy plus single or bilateral salpingectomy, dilating cervical canal as well as resecting adhesions. Twelve cases with adhesion inside uterine cavity followed hysteroscopy were also treated by dilating cervical canal, underwent adhesionlysis and hysterectomy. Conclusions The potential factors causing complications of hysteroscopy include complicated procedures inside uterine cavity, higher pressure of irrigation, deep injury of endometrium as well as incomplete removal of endometrium during hysteroscopic operations. It is the necessary measures to reduce the complications by performing laparoscopy or B ultrasound monitoring simultaneously, standardizing the procedure and strengthening postoperation management.

Human bocavirus 1 (HBoV1) is a novel virus that mainly causes respiratory tract infection, and it has the characteristic of genome of Parvovirus, containing three open reading frames that encode non-structural proteins NS1 and NP1 and structural proteins VP1 and VP2. Circular episome is present during the rolling circle replication of HBoV1, which provides the possibility of full genome amplification and infectious clone construction to save HBoV1. The recombination between HBoV1 and HBoV2-4 occurs frequently. With the three-dimensional culture, in vitro culture of HBoV1 provides a powerful tool for research on the pathogenesis of HBoV1. This review focuses on the molecular characteristics, association with diseases, in vitro culture, diagnosis and treatment of HBoV1.

Puerariae Lobatae Radix, also known as Gegen, is a root derived from Pueraria lobata. Based on field investigation and the developmental anatomy of root tuber, we have elucidated the relationship between the growth of root tuber and the anomalous structure. The results of analysis showed that the root system of P. lobata was developed from seed and adventitious root and there existed root tuber, adventitious root and conductive root according to morphology and function. The root tuber was developed from adventitious root, its secondary structure conformed to the secondary structure of dicotyledon's root. With the development of root, the secondary phloem of root tuber appeared abnormal vascular tissue, which was distributed like ring in the outside of secondary vascular tissue. The root tuber might have 4-6 concentric circular permutation abnormal vascular tissuelobate, and was formed by the internal development of abnormal vascular tissue. The xylem and phloem of abnormal vascular tissue were the main body of the root tuber. The results reveal the abnormal anatomical structure development of P. lobata, also provides the theoretical basis for reasonable harvest medicinal parts and promoting sustainable utilization of resources of P. lobata.

AIM To study the pharmacokinetics and bioavailability of clinafloxacin in rats. METHODS The drug concentration was determined by HPLC. The main pharmacokinetic parameters were obtained by 3P87 program. An RP-C18 was used as the stationary phase. The mobile phase was a mixture of acetonitrile-0.05 mol*L-1 citric acid triethylamine (pH 2.5) (20∶80). The flow rate was 1.0 mL*min-1. The UV absorbance detector was set at 300 nm. RESULTS A good linearity was obtained from 0.03-20 μg*mL-1 of clinafloxacin in rat plasma with γ=0.9998. The plasma concentration-time curve of clinafloxacin conformed to one compartment open model. After ig administration of 50 mg*kg-1 and 100 mg*kg-1 dose of clinafloxacin in six rats, mean Cmax and AUC values increased in proportion to dose. Mean T1/2 appeared to be independent of dose. Mean AUC was 65±6 and 27±4 μg*h*mL-1 respectively after iv and ig adminostration of 100 mg*kg-1 dose. The extent of bioavailability (F) of clinafloxacin was 42%. CONCLUSION The results of the pharmacokinetic study of clinafloxacin showed that it exhibited first order kinetic characteristics and the bioavailability is low.
