Three-dimensional conformal radiation therapy(3DCRT) is a new physical method which can enhance the therapeutic gain factor(TGF) of radiotherapy. It can escalate the doses of local tumor and decrease the doses of normal tissue. For patients with primary liver tumors, 3DCRT can increase the local control rates, prolong patients survival and decrease the incidence of radiation-induced complications.

Objective To explore the relationship between temperature and change of serum electrolytes (potassium, natrium, chlorine,and calcium) in patients with spinal cord injury. Methods 321 patients with spinal cord injury (SCI) following fever were regarded as observation group, while 313 SCI patients in normal temperature as control group. The level of serum electrolytes (potassium, natrium, chlorine, and calcium) in both groups was analyzed. Results There was no significant difference in the level of serum potassium (P>0.05), but was in the serum natrium, chlorine, and calcium (P<0.05) between 2 groups. The level of serum potassium didn't correlated with their temperature, and the level of serum natrium, chlorine, and calcium correlated with the temperature negatively. Conclusion The level of serum natrium, chlorine, and calcium may decrease in SCI patients following fever while the level of serum natrium is unchanged.

Objective To investigate the associated effect of 125I implantation plus chemotherapy in local recurrent stage Ⅲ NSCLC patients.Methods From January 2006 to January 2009,34 patients documented with local recurrent stage Ⅲ NSCLC were divided into two groups by random number table.The treatment group was treated with 125I permanent implantation combined with DP regimen (docetaxel 60 mg/m2 + cisplatinum 75 mg/m2),while the control group received only DP chemotherapy.According to the TPS,the treatment group received CT-guided percutaneous implantation of 125 I seeds with a particle activity of 2.22 ×107-2.59 × 107 Bq.The prescribed dose was in the range of 90-110 Gy and the postoperatively matched peripheral dose (mPD) and D9o were verified by TPS.The control group received a DP chemotherapy regime for 4 cycles after the procedure.This study was approved by the ethics committee,and all patients signed informed consents.The follow up time was up to disease progression.Kaplan-Meier survival analysis was used to describe the local lesion control (LLC) time and progression free survival (PFS).Log-rank test was used in the comparison of the survival rates between the two groups.Fisher's exact test was used to analyze the differences of CR rate and recent efficiency between two groups.Results In the treatment group,postoperative mPD was 93.9-130.4 (M 116.7) Gy,and D90 was 103.6-148.2 (M 130.6) Gy.The LLC time was 4.7 to 24.0 months with a median of 11.6 (95％ CI:8.7-14.6) months.In two cases,there was no recurrence during the follow-up time of 24 months.PFS was 4.7 to 24.0 months with a median of 10.5 (95％ CI:7.4-13.6) months.The recent effective rate of the treatment group was 64.7％ (11/17).CR,PR,SD and PD were 41.2％ (7/17),23.5％ (4/17),23.5％ (4/17) and 11.8％ (2/17),respectively.In the control group,the LLC time was 4.5 to 11.4 months with a median of 7.5 (95 ％ CI:6.7-8.3) months,and the median of PFS was 6.5 (4.5-10.5) (95％ CI:5.7-8.3) months.The response rate,CR,PR,SD and PD were 41.2％ (7/17),5.9％ (1/17),35.3％ (6/17),35.3 ％ (6/17) and 23.5％ (4/17),respectively.There was no statistical significance of the recent effective rate between the treatment group and control group (P =0.30),but the LLC time (x2 =8.40,P ＜ 0.01),the median of PFS time (x2 =6.27,P ＜ 0.05) and CR (P =0.04) of the treatment group were all significantly higher than those of the control group.Concltusion The implantation of 125I seeds combined with chemotherapy for recurring stage Ⅲ NSCLC patients is safe and effective,and its efficacy is superior to the second line chemotherapy alone.

Background and purpose:Multiple microRNAs (miRNAs) are abnormally expressed in breast cancer and play an important role in the regulation of breast cancer. miRNAs may be a new target for the treatment of breast cancer. This study aimed to investigate the expression of miR-199a-3p in breast cancer and the effect of miR-199a-3p on proliferation and apoptosis of breast cancer.Methods:Real-time PCR was used to test the expression of miR-199a-3p in breast cancer tissues, normal breast tissues, breast cancer cells and normal breast cells. Overexpression (or silencing the expression) of miR-199a-3p was conducted by transfecting MDA-MB-231 with miR-199a-3p mimics (or inhibitors). The proliferation of MDA-MB-231 was detected by MTT method. The apoptosis of MDA-MB-231 was investigated by Hoechst staining and caspase-3 activity assay kit.Results:Compared to corresponding non-tumor breast tissues (or normal breast cell HBL-100), lower levels of miR-199a-3p were expressed in breast cancer tissues or breast cancer cells. Overexpression of miR-199a-3p induced by miR-199a-3p mimic inhibited the proliferation and promoted the apoptosis of MDA-MB-231, while silencing the expression of miR-199a-3p induced by miR-199a-3p in-hibitor increased the proliferation and suppressed the apoptosis of MDA-MB-231.Conclusion:The expression of miR-199a-3p is lower in breast cancer, which shows its tumor suppression effect by regulating the proliferation and apoptosis of breast cancer cells.

Objective:To study the correlation among lipoprotein (a) [Lp (a)] ,its gene polymorphism and degenera‐tive calcific aortic valve disease (DCAVD) .Methods :From Feb 2010 to Jan 2014 ,a total of 164 DCAVD cases trea‐ted in our hospital were enrolled as DCAVD group ,another 164 healthy subjects undergoing physical examination in the same period were selected as normal control group .Relationship among Lp (a) level ,its gene polymorphism and aortic valvular calcification was compared and analyzed ,and Logistic regression analysis was used to analyze in‐dependent risk factors of DCAVD . Results :Lp (a ) gene possesses four point mutations in population , namely rs10455872 ,rs6415084 ,rs3798221 and rs7770628. In DCAVD group ,Lp (a) level of AG genotype was significantly higher than that of AA genotype [ (325.5 ± 108.2) mg/L vs .(211.7 ± 135.4) mg/L] in rs10455872 gene pheno‐type ,Lp (a) level of CC+TT genotype was significantly higher than that of CT genotype [ (287.9 ± 144.1) mg/L vs .(240.7 ± 127.2) mg/L] in rs6415084 gene phenotype ,and Lp (a) level of TT+ CC genotype was significantly higher than that of CT genotype [(304.1 ± 124.1) mg/L vs .(226.8 ± 101.6) mg/L] in rs7770628 gene phenotype , P<0.05 or <0.01 ;patient′s percentage of valvular calcification of AG genotype was significantly higher than that of AA genotype (90.0% vs .61.7% ) in rs10455872 , patients percentage of valvular calcification of CC +TT geno‐type was significantly higher than that of CT genotype (83.8% vs .66.7% ) in rs6415084 ,and patient′s percentage of valvular calcification of TT+CC genotype was significantly higher than that of CT genotype (87.3% vs .63.4% ) in rs7770628 , P<0.05 or <0.01. Logistic regression analysis indicated that rs10455872 ,rs6415084 ,rs7770628 and Lp (a) level were independent risk factors for valvular calcification of DCAVD (OR=1.67~2.31 , P<0.01 all) . Conclusion :Lp (a) gene polymorphism (rs10455872 ,rs6415084 and rs7770628) and plasma Lp (a) level are signifi‐cantly correlated to valvular calcification of DCAVD ,which may be susceptible genes for DCAVD occurrence .

Objective To explore the effect of carbohydrate administration on postoperative insulin resistance after gastroenteric tumor resection.Methods Sixty elective gastroenteric tumor resection patients were divided into observation group and control group by random number table method,with 30 cases in each.Observation group was given carbohydrate administration before surgery,that was 2 h before anesthesia oral carbohydrates 300 ml containing 50 g glucose;control group was treated according to the traditional methods,preoperative fasting 12 h,6 h forbidden to drink.The blood samples were collected to measure the levels of fasting blood glucose (FBG) and fasting insulin (FINS) at 3 h before operation and 1,3,7 d postoperation respectively.Homeostasis model assessment (HOMA) was applied to calculate the insulin resistance index.Results The levels of FBG,FINS,HOMA-IR at 1,3 d postoperation in two groups were significantly higher than those at 3 h preoperation [observation group:(10.65 ± 1.78),(7.32 ± 1.48) mmol/L vs.(5.09 ±0.43) mmol/L,(25.78 ± 12.43),(16.23 ±7.56) mU/L vs.(10.48 ± 1.57) mU/L,11.67 ±6.32,5.12 ± 2.11 vs.2.35 ± 0.54;control group:(11.18 ± 1.25),(8.04 ± 1.53) mmol/L vs.(5.12 ± 0.39) mmol/L,(39.67 ± 10.37),(24.34 ± 6.78) mU/L vs.(9.98 ± 2.04) mU/L,19.07 ± 5.49,8.56 ± 2.87 vs.2.28 ± 0.39](P ＜ 0.05).The levels of FINS,HOMA-IR at 1,3 d postoperation in control group were higher than those in observation group (P ＜ 0.05).The levels of FINS and HOMA-IR at 7 d postoperation in observation group were returned to the 3 h preoperative (P ＞ 0.05),while the levels in control group [(16.32 ± 4.56) mU/L,3.87 ± 1.12] was still higher than those at 3 h preoperation (P ＜0.05).Conclusion Carbohydrate administration may shorten the insulin resistance durion after gastroenteric tumor resection,and reduce the intensity of insulin resistance,thus contributing to the rehabilitation of patients.

Objective To explore the clinical aspects and related EEG characteristics of epilepsy (EP) in children with cerebral palsy (CP).Methods The clinical data and the EEG Results of seizure-interictal-period in 84 CP children complicated with EP were collected and compared with the data of 124 CP children without EP.Results Among 84 CP children complicated with EP, 46 cases (54.76%) were partial seizures. Followed 26 cases (30.95%) were infantile spasms, 6 cases (7.14%) were tonic-clonic seizures. Spastic CP children tended to be the most patients seizures in EP, it was 82.14%. Children with teraplegia CP were the most type among the spastic CP children compliated with EP. The abnormal rate of EEG of CP children complicated with EP was significantly higher than that of CP children without EP ( P＜0.001), and local epilptiform discharges and multilocal epileptiform discharges were main types.Conclusion Partial seizures is the most epilepsy type in CP children complicated with EP, and spastic CP is the main type. EEG abnormal ratio is obviously higher in the CP children complicated with EP than the CP children without EP. The types of abnormal EEG are mainly local epilptiform discharges and multilocal epileptiform discharges.

Objective To probe the therapeutic effect of ginger-salt-partitioned moxibustion on urge incontinence after stroke. Methods 40 stroke patients following urge incontinence were randomly divided into control group (n=20) and experimental group (n=20). 2 groups all received the same treatment, routine acupuncture and rehabilitation. Additionally, the experimental group received ginger-salt-partitioned moxibustion at Shenque (CV8). The curative effect was compared after treatment (4 weeks). Results 36 cases finished the treatment, 17 in the control group and 19 in the experimental group. Total number of urination, urinary incontinence and nocturia reduced, and the average volume of each urine increased (P<0.05), and volume of bladder residual urine reduced in 2 groups after treatment (P<0.001), while the experimental group was better than the control group (P<0.05). The scores of modified Barthel Index increased in 2 groups after treatment, but there was no significant difference between 2 groups (P>0.05). Conclusion The effect of ginger-salt-partitioned moxibustion at Shenque on poststroke following urination disorders is remarkable.
