The rice gall dwarf disease, caused by the Rice gall dwarf virus (RGDV) is a serious disease occurring in rice in many regions of Guangdong province. As a basis to control the disease we have studied the genomic diversity of a variety of isolates from different locations. Genome segment 8(S8), encoding a main outer capsid protein (Pns8) of RGDV five isolates (BL, CH, DQ, GZ, XY) from Guangdong province was cloned and sequenced. The results revealed that all the S8 segments of the five isolates consisted of 1 578 nucleotides and had a single open reading frame (ORF) extending for 1 301 nucleotides from nucleotide 21 which encoded a polypeptide of 426 amino acids with an estimated molecular weight of 47.4 kDa. The S8 full-length sequence and the ORF sequence shared 97.3%-98.8% and 97.3%-99.1% nucleotide sequence identities within the five Chinese isolates, and shared 94.8%-95.6% and 95.0%-96.0% identities with those of the Thailand isolate respectively. The deduced amino acid sequence of Pns8 in GZ isolate was identical to that in the Thailand isolate, while the amino acid sequence variability of Pns8 within five Chinese isolates ranged from 0.5% to 2.1%. These results indicate that the S8 segment of RGDV is highly conserved in different isolates from different locations. The S8 cDNA from the XY isolate was cloned into the plasmid vector pET-28b(+) and a fused expression protein with an apparent molecular mass of 51kDa was specifically detected in an analysis of Escherichia coli Rossetta(DE3)Ⅱcells. To our knowledge, this is the first report on analysis of the RGDV segment 8 sequence and genetic comparison of different RGDV isolates and their protein expression.

OBJECTIVETo explore the distribution characteristics of basic syndromes and its related factors in patients with chronic functional constipation (CFC).

METHODSThe complete data of 538 patients with CFC were collected and initial database was established with Epidata 3. 0. TCM syndrome typing was performed. The distribution characteristics of basic syndromes were analyzed using SPSS 17. 0 Software. The univariate and multivariate Logistic regression analyses were performed with SPSS 17. 0 Software to determine basic syndrome related factors such as age, engaged professionals, sleep quality, depression, mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation, and so on.

RESULTSThe TCM syndrome frequency of CFC patients was sequenced from high to low as qi deficiency syndrome (380 cases, 70.6%), qi stagnation syndrome (337 cases, 62.6%), blood deficiency syndrome (234 cases, 43.5%), yin deficiency syndrome (220 cases, 40.9%), yang deficiency syndrome (197 cases, 36.6%), and others(58 cases, 10. 8%) . Most patients were complicated with complex syndromes, and the most common complex syndromes were qi deficiency complicated qi stagnation syndrome (275 cases, 51.1%) and qi deficiency complicated blood deficiency syndrome (222 cases, 41.3%). Aging, work fatigue, and exercise conditions were main related factors for qi deficiency syndrome (P <0. 01, P <0. 05). Poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, defecation barriers constipation were main related factors for qi stagnation syndrome (P <0.01). Sleep quality and poor emotional (depression and anxiety tendencies) were main related factors for blood deficiency syndrome (P <0. 01, P < 0.05). Stimulating beverages were main related factor for yin deficiency syndrome (P <0.05). Engaged in mental work and slow transit constipation were main related factors for yang deficiency syndrome (P < 0. 01, P <0. 05).

CONCLUSIONSCFC is featured as complex syndromes. The most common complex syndromes were qi deficiency complicated qi stagnation syndrome and qi deficiency complicated blood deficiency syndrome. Basic syndrome related factors such as age, engaged professionals, sleep quality, poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation were associated with the distribution of CFC syndromes.

U-shaped sacral fractures are rare and often difficult to diagnose primarily due to the difficulty in obtaining adequate imaging and the severe associated injuries.These fractures are highly unstable and frequently cause neurological deficits.The majority of surgeons have limited experience in management of U-shaped sacral fractures.No standard treatment protocol for U-shaped sacral fractures has been available till now.This study aimed to examine the management of U-shaped sacral fractures and the early outcomes.Clinical data of 15 consecutive patients with U-shaped sacral fracture who were admitted to our trauma center between 2009 and 2014 were retrospectively analyzed.Demographics,fracture classification,mechanism of injury and operative treatment and deformity angle were assessed.All the patients were treated with lumbopelvic fixation or (and) sacral decompression.EQ-5d score was applied to evaluate the patients' quality of life.Of the 15 consecutive patients with U-shaped sacral fracture,the mean age was 28.8 years (range:15-55 years) at the time of injury.There were 6 females and 9 males.The mean followup time was 22.7 months (range:9-47 months) and mean full weight-bearing time was 9.9 weeks (range:8-14 weeks).Ten patients received lumbopelvic fixation and sacral decompression,one lombosacral fixation,and 4 merely sacral decompression due to delayed diagnosis or surgery.The post-operation deformity angle (mean 27.87°,and range:8°-90°) of the sacrum was smaller than that pre-operation (mean 35.67;range:15-90) with no significance difference noted.At the latest follow-up,all patients obtained neurological recovery with different extents.Visual analogue score (VAS) was reduced from preoperative 7.07 (range:5-9) to postoperetive 1.93 (range:1-3).All patients could walk without any aid after treatment.Eight patients were able to care for themselves and undertook some daily activities.Five patients had returned to work full time.In conclusion,lumbopelvic fixation is an effective method for stabilization of U-shaped sacral fractures with fewer complications developed.Effective reduction and firm fixation are the prerequisite of early mobilization and neurological recovery.Sacral decompression effectively promotes neurological recovery even in patients with old U-shaped sacral fractures.

Objective To assess the effect of leukocyte fihration on systemic inflammatory response to cardiopulmonary bypass.Methods Twelve mongrel dogs weighing 25-30 kg were randomly divided into 2 groups (n=6 each):control group(C)and leukocyte depletion group(LD).The dogs were anesthetized with intraperitoneal pentobarbital 25 mg?kg~(-1).The trachea was intubated.The arterial line of CPB was connected with aortic cannula and the venous line with a cannula inserted into right atrium.The leukocyte-depletion filter LD-1 was positioned in the venous line of CPB circuit.Aorta was clamped at 10 min of CPB and St.Thomas cardioplegic solution 20 ml?kg~(-1) was injected into the root of aorta.The filter was used for 5 min starting from 2 min of CPB. Aorta was clamped for 60 min.Blood samples were taken from femoral vein before CPB(T_0,baseline), immediately after aortic clamping(T_1)at 30 min of aortic clamping(T_2)5 min after aortic unclamping(T_3)at the termination of CPB(T_4)and 2 h after termination of CPB(T_5)for leukocyte count and determination of plasma L-selectin,IL-6 and IL-8 concentrations and MPO activity.The IL-6 and IL-8 concentrations in the filter LD-1 were measured at 30,60 and 90 rain after leukocyte filtration.The membrane of filter LD-1 was taken at 90 min after filtration for microscopic examination.Results The leukocyte count was significantly lower at T_1 in LD group than in C group.The plasma L-selectin,IL-6,IL-8 concentrations and MPO activity were significantly increased during CPB as compared to the baseline at T_0 in both groups but were lower at T_5 in LD group than in C group.The IL-6 and IL-8 concentrations in LD-1 filter were increased at 60 and 90 min after filtration as compared to those at 30 min.The filter membrane was covered with enormous number of leukocytes.Conclusion Leukocyte filtration can decrease systemic inflammatory response to CPB in dogs.

OBJECTIVETo compare the clinical effectiveness of blind intubation through the Cookgas intubating laryngeal airway(CILA) or Fastrach intubating laryngeal mask airway(FT-LMA) for anticipated difficult tracheal intubation.

METHODSEighty-six patients with anticipated difficult tracheal intubation who were undergoing elective plastic surgery under general anesthesia were randomly allocated into CILA group(n=43) and FT-LMA group(n=43) . After general anesthesia being induced and CILA or FT-LMA being inserted, the patients were treated with blind intubation through CILA or FT-LMA. In each case, the number and the time of intubating laryngeal airway(ILA) insertion and blind intubation attempts and ILA removal were recorded. The view of glottis under fiberoptic bronchoscope(FOB) via CILA or FT-LMA was recorded. In addition, noninvasive blood pressure and heart rate were recorded before and after intravenous anesthetic induction, at ILA insertion, at intubation, at ILA removal and every minute thereafter for 5 minutes.

RESULTSCILA or FT-LMA was inserted successfully in all 86 patients. The rate of the first successful insertion was not significantly different between two groups(P>0.05) . In CILA group, the first intubation attempt succeeded in 35 patients;5 and 2 cases were intubated blindly at the second and the third attempt, one patient failed who was intubated successfully by FOB via CILA. In FT-LMA group, 32 patients were intubated successfully at the first attempt, 4 at the second attempt, 3 at the third attempt, and 4 cases failed, three of them were intubated smoothly with FOB through FT-LMA, one failed patient was intubated by FOB. The time of FT-LMA insertion(34.2∓13.9) s was significantly longer when compared with CILA(22.4∓18.9) s (P<0.05) . However, the time of blind intubation through CILA and FT-LMA [(46.0∓26.7) s vs.(51.8∓41.1) s]and the time of ILA removal[(39.3∓11.9) s vs.(35.3∓10.4) s] were not significantly different between groups(P>0.05) . Hemodynamic changes during blind intubation in the two groups showed no significant differences(P>0.05) .

CONCLUSIONSBlind intubation via CILA or FT-LMA is safe and effective for anticipated difficult tracheal intubation. Nevertheless, CILA is easier to be inserted, with relatively higher success rate of blind intubation.

OBJECTIVETo investigate the feasibility and advantages of transurethral transumbilical laparoendoscopic single-site surgery (TU-LESS) for radical prostatectomy.

METHODSFive patients with prostate cancer underwent TU-LESS for radical prostatectomy, with a four-channel single-port device inserted into a 2. 5 cm periumbilical incision and another placed through the urethra, followed by analysis of the perioperative data.

RESULTSAll the operations were successfully accomplished, with neither conversion to open surgery nor additional channel. The mean operation time, intraoperative blood loss, and postoperative hospital stay were 168 min, 120 ml, and 15 d, respectively. No severe perioperative complications were observed. TNM stage classification manifested T2cN0M0 in 2 cases and T2bN0M0 in the other 3. Postoperative pathology showed no negative surgical margins in any of the cases.

CONCLUSIONTU-LESS is safe and feasible for radical prostatectomy and can reduce the complication of low urinary tract surgery by single-site laparoendoscopy.

This study was aimed to detect the methylation status of FHIT gene promoter region in the DNA from plasma of patients with myelodysplastic syndrome (MDS), and to investigate the demethylating effect of decitabine. Methylation-specific PCR method was used to detect the methylation status of FHIT gene promoter region in the DNA from plasma of 4 patients with MDS before and after treatment with decitabine plus semis CAG therapy (among them, 1 case of newly diagnosed MDS, 3 cases progressed into acute leukemia). The results indicated that 3 cases were found to have an increased methylation in the promoter region. After treatment with decitabine plus semis CAG, increased methylation was reversed in 2 cases. In 4 cases, 2 cases displayed clinical response. It is concluded that FHIT gene hypermethylation is associated with MDS pathogenesis. Decitabine has demethylating effect on the FHIT gene hypermethylation of plasma from MDS patients. Detecting the methylation status of FHIT gene in DNA from plasma may play a role in MDS auxiliary diagnosis or prognosis.
