Objective To evaluate the key points of anesthetic management for retroperitoneoscopic nephrectomy combined with inferior vena cava ( IVC ) tumor thrombectomy. Methods Perioperative clinical data of 3 patients undergoing retroperitoneoscopic nephrectomy combined with IVC tumor thrombectomy from December 2010 to June 2014 were retrospectively analyzed.There were 2 cases of level Ⅰthrombus and 1 case of level Ⅱthrombus.All the patients were given general anesthesia with intubation.Brief inferior vena cava occlusion was performed in the patient with level Ⅱ thrombus. Results The operation was completed smoothly in all the cases without conversions to open surgery. The operating time was 244, 333, and 289 min, respectively. The total IVC control time for level Ⅱ thrombus was 10 min.No intraoperative pulmonary embolism and other severe anesthetic complications occurred. One patient with level ⅠIVC thrombus was extubated and sent back to surgical ward after surgery, and the remaining 2 patients underwent intensive care monitoring overnight and were extubated and discharged to surgical ward on the next day. Conclusions Retroperitoneoscopic nephrectomy and IVC thrombectomy is a brand-new, difficult but feasible procedure. Anesthesiologist should have a full recognition of surgical procedures and make perfect anesthetic plan to ensure close collaboration. Furthermore, circulatory swing during IVC clamping and perioperative severe complications such as pulmonary embolization and massive hemorrhage cannot be neglected.

[Summary] Regional cerebral oxygen saturation ( rSO2 ) can be used to monitor the changes of cerebral oxygen demand and supply, and postoperative cognitive dysfunction ( POCD ) is a relatively common adverse effect following cardiac surgery. The intraoperative rSO2 decrease may associate with the incidence of POCD. Real-time intraoperative monitoring of rSO2 and necessary interventions performed to correct cerebral rSO2 desaturation may reduce the incidence of POCD of cardiac surgery.

The authors described two cases with primitive trigeminal artery. Case 1 was a 32-year-old woman who suffered dizziness and a serious pulsatile intracranial bruit on the left ear, and sometimes associated with pulsatile intracranial bearing-pain on the left temporal side six months before she was admitted to the hospital. She also suffered from obvious diplopia on left lateral gaze for the last 5 months. She had suffered no recent trauma. Magnetic resonance imaging(MRI) demonstrated a suspected intracranial aneurysm located in left cavernous sinus. Digital subtraction angiography (DSA) was performed and a primitive trigeminal artery-cavernous sinus fistula in left side was found. Intraluminal occlusion of the fistula was successfully performed immediately after angiography using 6 Guglielmi detachable coils (GDC), and the patient was cured finally. Case 2 was a 28-year-old woman who suffered a serious intermittent cephalodynia associated with soreness on the left body two years before she was admitted to the hospital. She had suffered no recent trauma. Magnetic resonance angiography(MRA) demonstrated a suspected intracavernous aneurysm of the right internal carotid artery, Digital subtraction angiography (DSA) was performed. Right internal carotid angiography showed a primitive trigeminal artery (PTA) run between the cavernous segment of the internal carotid artery and the distal portion of the basilar artery. On initiation of PTA of R-ICA a small wide-necked saccular aneurysm was incidentally visualized. The aneurysm was successfully embolized after angiography using 2 Stent (Neuroform, 4.5mmm × 20mmm)-assisted detachable coils (Matrix), the ICA and PTA were preserved, and the patient was cured finally.

This study is to establish the methods for determination of iridoid glycosides and triterpenic acids in Corni Fructus and provide technical support for the quality control of Corni Fructus. Morroniside, loganin and sweroside were determined by HPLC-UV method with acetonitrile and 0.1% formic acid as the mobile phase, and the detective wavelength was set at 240 nm. Oleanolic acid and ursolic acid were determined by HPLC-ELSD method with methanol-0.5% ammonium acetate (87:13) as the mobile phase. The results showed that the linear ranges of morroniside, loganin and sweroside were 5.335-213.4 mg · L(-1) (r = 0.9999), 5.515-220.6 mg · L(-1) (r = 1.0000), 1.992-79.68 mg · L(-1) (r = 1.0000), respectively. The average recoveries of the above three iridoid glycosides were 98.49%-99.28% with RSDs of recoveries being less than 2%. The linear ranges of oleanolic acid and ursolic acid were 7.74-154.8 mg · L(-1) (r = 0.9964), 10.82-216.4 mg · L(-1) (r = 0.9996), respectively. The average recoveries of the above two triterpenic acids were 98.11%-99.27% with RSDs of recoveries being less than 3%. The method established in this research is simple, rapid and reliable, and can be used for quality control of Corni Fructus. Furthermore, the research provided experimental data for the improvement of present quality standard of Corni Fructus, which has important significance to guarantee its quality and clinical curative effect.

This study aimed to amplify major genome segments (VP7, VP4, VP6, VP2 and NSP2-5) of porcine G3 group A rotavirus (GARV) LLZ212 isolated in our laboratory, determine their genotypes, and explore the evolutionary relationships between G3 GARV strains isolated from humans and pigs in Lulong County, Hebei Province, China. Major genome segments of seven GARV strains were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and the segments were sequenced. The genome segments of seven GARV strains were determined by the online RotaC genotyping tool (RotaC v2.0). The reference sequences of each GARV genome segment were downloaded from GenBank. Homology and phylogenetic evolutionary analyses were conducted using the MEGA 5.0 and DNAStar software packages. LLZ212 isolated from pigs in Lulong had the following genotype: G3-P[8]-I5-C1-N1-T1-E1-H1. All human GARV strains had the following genotype: G3-P[8]-I1-C1-N1-T1-E1-H1. The VP7, VP4, NSP4 and NSP5 genes of the LLZ212 strain had the highest nucleotide identities with the human GARV E885, CMH014/07, Wa and RMC321 strains, respectively, and these clustered together in a sublineage. The VP6, NSP4 and NSP5 genes of the LLZ212 strain shared the highest nucleotide identities with the porcine GARV PRG921 strain, while VP2 associated most closely with porcine GARV OSU strain, and these also clustered in a sublineage. A rare porcine G3-P[8]-I5-C1-N1-T1-E1-H1 GARV strain was identified, which may represent a reassortment between porcine and human viruses. In conclusion, the VP7, VP4, NSP4 and NSP5 genes of LLZ212 share high levels of sequence identity with human GARV, while VP2, VP6, NSP2 and NSP3 cluster with porcine GARV.

OBJECTIVE:To investigate the improvement effects of Zhuanggushenjin capsules on osteoporosis induced by reti-noic acid in mice. METHODS:84 mice were randomly divided into normal control group,model control group,positive control group [Gushukang granules,5 g(crude drug)/kg] and Zhuanggushenjin capsules high-dose,medium-dose and low-dose groups [7.80,3.90,1.95 g(crude drug)/kg]. Except for normal control group,those groups were given retinoic acid(90 mg/kg)to induce osteoporosis model. 7 days after modeling,all drug groups were given relevant medicine intragastrically,normal control group and model control group given normal saline intragastrically ,once a day,for consecutive 14 days. ALP activity and the contents of cal-cium and phosphorus in serum and thigh-bone were determined. The body weight, the dry weight, length and diameter of thigh-bone were determined,and organ coefficients (spleen,testicle,ovarium and uterus) were calculated. RESULTS:Compared with normal control group,the activity of ALP in serum of mice increased in model control group,while the contents of calcium and phosphorus,body weight,length and diameter of thigh-bone decreased significantly;spleen coefficients increased,while testi-cle and uterus coefficients decreased(P<0.05 or P<0.01). Compared with model control group,the contents of calcium and phos-phorus increased in Zhuanggushenjin capsules groups,while spleen coefficient decreased;the activity of ALP in serum of mice de-creased in high-dose and medium-dose groups,while body weight,the length of thigh-bone,testicle and uterus coefficients in-creased;diameter of thigh-bone increased in high-dose group (P<0.05 or P<0.01). CONCLUSIONS:Zhuanggushenjin capsules can improve retinoic acid-induced osteoporosis in mice to certain extent.

Rotavirus is the leading causal agent of severe acute gastroenteritis in children aged <5 years. A specific pharmacologic agent for the treatment of rotavirus-infected children is lacking. In China, only the Luo Tewei oral vaccine (Lanzhou Institute of Biological Products, Shanghai, China), which is produced from Lanzhou lamb rotavirus vaccine (LLR), is available. Studies have hypothesized that the genotype of LLR is G10P[12], To identify the genotype of LLR by reverse transcription-polymerase chain reaction, we showed that the VP7 and VP4 genotypes of LLR were G10 and P[15], respectively, based on sequencing, alignment and phylogenetic analyses. In conclusion, we identified the genotype of rotavirus strain LLR to be G10P[15].

This study aimed to study the epidemiological and clinical characteristics of human bocavirus 1-4 (HBoV1-4) in children with acute diarrhea in Lanzhou and to investigate the association between HBoV and acute gastroenteritis. A total of 331 stool samples were collected from children aged under 5 years with acute diarrhea at the Department of Pediatrics, the First Hospital, Lanzhou University, between July 2012 and June 2013. Nested PCR was used to screen for HBoV and a general PCR was employed to screen other common diarrhea viruses. We found human bocavirus 1, 2, 3 and 4 in 26, 15, 7 and 1 cases, respectively. There was no specific seasonal distribution of HBoV, with infections occurring throughout the year. HBoV was mostly found in children aged between 7 and 12 months, with a mean age of 11.04 months (+/- 6.92 months), and 93.88% of affected children were aged under 2 years. Overall, 71.3% of mixed infections were mixed and the majority of other infections were caused by rotavirus. There was no statistical difference in the incidence of fever and vomiting associated with HBoV infection. A rare virus strain, HBoV4 (LZFB086), was identified, which showed highest levels of nucleotide sequence identity (99.0%) with a single Thai HBoV strain (JQ267789). No case of HBoV2B was found. In conclusion, HBoV1 was a major etiological pathogen of HBoV in pediatric cases in Lanzhou. HBoV4 was detected in feces for the first time in China. The rate of mixed infections was high and rotavirus was dominant. The data presented suggests that HBoV is not a major causative agent of gastroenteritis.

Abstract:This study aims to investigate the genetic characteristics of group A rotavirus (GARV) G9P[8] strains from infantile diarrhea samples in Hebei Lulong region from 2009 to 2011. We randomly selected five GARV G9P[8] strains in Hebei Lulong region from 2009 to 2011, amplified the 11 gene fragments of GARVs by RT-PCR, and analyz their full-genome sequences by homology and phylogenetic analysis with DNAStar and MEGA. The nucleotide homology between strains LL11131077 and LL11131083 in 2011 was significantly higher than hat etween them and the other three strains in 2009 and 2010. The G9P[8] GARVs circulating in Hebei Lulong region from 2009 to 2011 elenged to the same genotype as the prevalent G9P[8] GARVs in other parts of the world. However,the two strains in 2011, compared with those in 2009 and 2010, were located in a different sub-branch of the phylogenetic tree and had amino acid mutations at many sites.
