Objective To investigate the effect of telephone call follow-up on compliance with opening-mouth exercises among nasopharyngeal carcinoma(NPC)patients with radiotherapy-induced difficulty in opening mouth.Methods Sixty four nasopharyngeal carcinoma patients undergoing radiotherapy were randomized into control group(n=31)and observation group(n=31).The former group was given health education and instructions for functional exercises of opening mouth at discharge and regular return visits after discharge,and the observation group received regular telephone call follow-ups by an appointed nurse besides the same treatment as in the control group.The two groups were compared in regard to the compliance with the exercises of opening mouth and the incidences of difficulties in opening mouth at the first and second years after discharge. Results The compliance of the observation group was significantly higher that in the control group(P<0.01).The incidences of difficulties in opening mouth in the observation group were significantly smaller than that in those of the control at the first and second years after discharge(P<0.01). Conclusion Telephone call follow-ups are effective in the improvement of compliance of functional exercises in NPC patients with radiotherapy-induced difficulty in opening mouth,the reduction of the incidence of mouth-opening problems and the improvement of their quality of life.

OBJECTIVETo research the clinical application of lower cervical pedicle screw fixation procedure.

METHODSFrom September 2011 to July 2013,32 patients underwent posterior pedicle screw-rod system fixation were retrospective analyzed includinig 20 males and 12 females with an average age of 56.4 years old ranging from 21 to 78 years. Among them, 10 patients were traumatic cervical spinal injury, 9 patients were cervical spinal canal tumors, 7 cases were posterior longitudinal ligament ossification of cervical vertebrae, 6 cases were multiple segmental cervical spondylopathy. Preoperatively, X-ray, computed tomography, magnetic resonance imaging and magnetic resonance angiography of the vertebral artery were performed in all patients. After the operation and during the follow-up,X-ray and computed tomography were performed to confirm the pedicle screw position. The accuracy of the pedicle screw placement was evaluated by 4 grades classification from Lee. The spinal cord function was assessed by ASIA impairment scale for traumatic patients and JOA score for non traumatic patients.

RESULTSTotally 144 pedicle screws performed on 32 patients from C3 to C7 involving 132 screws of grade 0,5 screws of grade 1,5 of screws grade 2 and 2 screws of grade 3 according to postoperative CT. There were 12 screws penetrating the pedicle cortex including 8 screws at lateral,2 screws at caudal, 1 screw at medial and 1 screw at cranial. The follow-up time was 12 to 33 months with an average of (21.0±1.5) months. The spinal cord function was not improved in 6 complete cervical spinal cord injury patients,but their paraplegic level descended 1 to 3 segments. Four incomplete cervical spinal cord injury patients' ASIA impairment scale was increased by 1 to 2 grades in average. The JOA score of 22 atraumatic patients increased from preoperative 11.5±0.8 to 15.9±0.6 of postoperative at 6 months (P<0.01). There were no screw loosening,screw pullout and screw-rod breakage.

CONCLUSIONThe lower cervical pedicle screw fixation can provide excellent 3D stability of the vertebral column. The operation risk and Complication could be minimized by adequate preoperative evaluation for appropriate cases and individual pedicle screw placement. It deserved the clinical expansion.

Objective To investigate the effect of one-lung ventilation (OLV) on the occurrence of subcutanous emphysema during retroperitoneal laparoscopic urologic surgery (RPLUS).Methods Twenty-seven ASA Ⅰor Ⅱ patients,aged 29-64 yr,with body mass index 19-25 kg/m2,scheduled for elective RPLUS,were randomly divided into 2 groups:two-lung ventilation (TLV) group (group Ⅰ,n =15) and OLV group (group Ⅱ,n =12).In group Ⅰ,the patients were tracheal intubated and TLV was performed.In group Ⅱ,the left-sided double lumen endobronchial tube was inserted and TLV was performed,OLV on the non-operated side was performed starting from 10-15 min before pneumoperitoneum and TLV resumed at the end of pneumoperitoneum.The end-tidal CO2 partial pressure and minute ventilation volume were measured before pneumoperitoneum (T1),at 30 and 60 min of pneumoperitoneum (T2,3),and at 30 min after the end of pneumoperitoneum (T4).The CO2 absorption capacity was calculated.The degree of pneumoderma was assessed and the occurance of pneumoderma was recorded at the end of pneumoperitoneum.Results Compared with group Ⅰ,the CO2 absorption capacity was significantly reduced,and the degree and incidence of pneumoderma were significantly decreased in group Ⅱ (P ＜ 0.05).Conclusion OLV on the non-operated side can reduce the CO2 absorption capacity,decrease the degree of subcutaneous emphysema and reduce the occurrence of subcutanous emphysema during pneumoperitoneum in patients undergoing RPLUS.

Hairy roots appeared in vitro 20 days after inoculation of Phytolacca esculenta leaf explants with the strain of Agrobacterium rhizogenes R1601. The frequency of leaf explants transformed by R1601 was up to 70%. Hairy roots can be incited directly from the veins of explants or via callus. Hairy roots induced by R1601 grew rapidly on medium MS without hormone and were 85.6% higher in respiration rate than control roots. Transformation was confirmed by opine detection and the amplification of rol B and rol C genes from the hairy roots of P. esculenta. The total saponin content in hairy roots of P. esculenta was about 1.54 times as much as in natural roots whereas polysaccharides content was about 70% times as much as in the natural roots.

MCP-1 level and MCA in bronchoalveolar lavage fluid (BALF) were measured. RESULTS: The concentration of MCP-1 and MCA in BALF in group A were much higher than those in group B and group C (P

OBJECTIVETo study the distribution of hepatitis B virus (HBV) genotype in population of Dong, Miao minority and Han in Guizhou.

METHODSS region nucleotides were compared in 127 strains whole sequence of HBV and three restriction enzymes which can be used for genotyping were found by DNA software analysis system. The partial gene fragment of HBV S region was amplified by nested polymerase chain reaction (nPCR). The products were digested with Mbo I, BstN I or BsmA I and subjected to electrophoresis on agarose gel, respectively. The patterns of restriction fragment length polymorphism (RFLP) were analysed. The genotypes were determined by nPCR-RFLP in 166 asymptomatic HBV carriers (ASC), including 48 Dong minority, 52 Miao minority and 66 Han subjects. Some of the ASC were also analysed by direct sequencing of PCR products.

RESULTSThe nPCR-RFLP method was simple and accurate. Of the 166 ASC, 138 (83.13%) were genotype B, and 28 (16.87%) were genotype C. Of the 48 Dong minority subjects, 47 (97.2%) were genotype B and 1 (2.08%) was type C. Of the 52 Miao minority subjects, 49 (94.23%) were genotype B and 3 (5.77%) were genotype C. Of the 66 Han subjects, 42 (63.64%) were genotype B and 24 (36.36%) were genotype C. There was a statistical significance in the distribution of genotype C between Dong, Miao minority and Han (7.85% vs 36.36% P less than 0.005).

CONCLUSIONGenotype B and C exist in Guizhou and genotype B is the major genotype. Genotype C is found more frequently in Han than in Dong and Miao minority.

This study was aimed to retrospectively analyze and compare the clinical curative efficacy of patients with hematologic malignancies after G-CSF-mobilized sibling HLA-matched (sm) peripheral blood hematopoietic stem cell transplantation (sm-allo-PBHSCT) and sm-allo-PBHSCT combined with bone marrow transplantation (BMT). 100 patients received sm-allo-HSCT in a single center from October 2001 to October to 2010, included 38 patients received sm-allo-PBHSCT and 62 patients received sm-allo-PBHSCT combined with BMT. The myeloablative or reduced intensity conditioning regimens were chosen according to the condition of patients. All patients received standard cyclosporine (CsA) and mycophenolate mofetil (MMF) as prophylaxis for GVHD. The results showed that the rapid hematopoietic reconstitution was observed in all patients. The median time of ANC ≥ 0.5 × 10(9)/L in both groups were 12 days, the median time of platelet count ≥ 20 × 10(9)/L was 15 days in sm-allo-PBHSCT group and 16 days in sm-allo-PBHSCT + BMT group. The incidence of acute GVHD, acute GVHD of III-IV grade and chronic GVHD in sm-allo-PBHSCT and sm-allo-PBHSCT + BMT groups were 37.1% and 34.2%, 7.89% and 8.06%, 36.11% and 41.38% respectively, there were no statistical differences. The relapse rates were similar in two groups (sm-allo-PBHSCT 13.16% vs sm-allo-PBHSCT + BMT 12.9%). The 3-year disease-free survivals in sm-allo-PBHSC and sm-allo-PBHSCT + BMT groups were 57.1 ± 8.7% and 61.3 ± 6.4% respectively (p = 0.852). The 2-year overall survival of high-risk patients was 41.4 ± 12.8% in sm-allo-PBHSCT group, while 60.9 ± 9.6% in sm-allo-PBHSCT + BMT group (p = 0.071). It is concluded that the rhG-CSF mobilized sibling matched allo-PBHSCT + BMT is superior to the rhG-CSF mobilized sibling matched allo-PBHSCT in increasing the overall survival of high-risk hematologic malignancies.

OBJECTIVETo explore the clinicopathological characteristics and prognostic factors of primary gastric lymphoma (PGL).

METHODSThe clinical data of 204 patients with PGL was reviewed and analyzed. There were 106 males and 98 females, their age were 19 to 85 years (average age was 53.7 years). The Focal areas included gastric fundus lesions 41 cases (20.1%), stomach body lesions 127 cases (62.3%), distal gastric lesions 105 cases (51.5%), cardia lesions 13 cases (6.4%), duodenal bulb lesion 1 cases (0.5%). The clinical characteristics and the outcomes in patients with influence were analysed.

RESULTSIn 204 PGL patients, the most common complaints were abdominal pain (62.3%) and weight loss (52.9%). Most of the PGL patients appeared ulcerative (76.0%) and results showed that 62.7% patients involved single location. As to the factors of cellulate grading and pathological characteristics, most patients (87.7%) show low-grade or intermediate-grade lymphoma, Musshoff stages I and II (74.0%). In 186 patients with complete follow-up data, survival rates of 1-, 3- and 5-year were 75.8%, 63.4% and 60.2% respectively. The median overall survival time was 50.0 months. In univariate survival analysis, age (χ(2) = 5.030), level of LDH (χ(2) = 40.084), cellulate grading (χ(2) = 35.238), Musshoff stage (χ(2) = 71.601), tumor diameter (χ(2) = 12.018) and option of managements (χ(2) = 14.140) were obviously correlated with the prognosis (all P < 0.05). Musshoff stage (RR = 2.230, 95%CI: 1.372 - 3.625) and cellulate grading (RR = 1.892, 95%CI: 1.010 - 3.543) were independent prognostic factors in multivariable analysis (both P < 0.05). There was no prognostic difference between surgery and chemotherapy in stage I and II (χ(2) = 1.223, P = 0.542).

CONCLUSIONSMusshoff stage and grade malignancy are independent prognostic factors. For patients with stage I and II, surgical resection is not the first-choice for clinical therapy.
