Objective To evaluate the effect of acupointhot compress with warming moxibustion bag on treating radiation proctitis caused by radiotherapy in cervical cancer. Methods 78 patients of cervical cancer with acute radioactive proctitis caused by radiotherapy were divided into two groups according to the length of hospital stays. The experiment group was given compress Tianshu acupoint with warm moxibustion bag every day, along with drug and retention enema, while the control group was treated with drug and retention enema only. Then observe and evaluate the effect of different treatment on each group. Results The total effective rate of treating radiation proctitis in experimental group was 94.44%(34/36) which was superior to 76.19% (32/42) of the control group (χ2=4.962, P<0.05). The influence of tumor radiotherapy in experimental group was also superior to the control group, nine patients were forced to suspend to radiotherapy by (6.11 ± 1.96) days in the control group, while five cases were suspended to radiotherapy by (2.20±1.09) days in the experiment group (t=4.066,P<0.05). Conclusions Acupoint hot compress with warming moxibustion bag combine with retention enema have an advantage over retention enema only on radiation proctitis caused by radiotherapy in cervical cancer.

Objective To investigate the effects of different doses of dexmedetomidine combined with propofol and remifentanil target controlled infusion (TCI) on postanesthesia recovery of patients in functional endoscopic sinus surgery. Methods Eighty ASA Ⅰor Ⅱ grade patients, scheduled for the endoscopic sinus surgery, were divided into control group (20 cases) and dexmedetomidine group (60 cases) according to the random digits table method. The patients in dexmedetomidine group were given loading dose dexmedetomidine 0.6 μg/kg, then were given dexmedetomidine of different maintenance doses:0.3 μg/(kg·h) in D1 group, 0.6 μg/(kg·h) in D2 group and 0.9 μg/(kg·h) in D3 group. The patients in dexmedetomidine group were given TCI propofol and remifentanil during the maintenance of general anesthesia, rocuronium was administrated intermittently during operation, and bispectral index (BIS) was controlled at 40 - 50. The changes of hemodynamics 5 - 10 min after entering operation room (T0), before induction (T1), 1 min after intubation (T2), 5 min after intubation (T3), before extubation (T4) and 5 min after extubation (T5) were observed. The spontaneous breathing recovery time, call of eye-opening time, extubation time and adverse reaction after surgery were recorded. Moreover, the visual analogue score (VAS) and Ramsay sedation score were used to evaluate the comfort level of patients. Results The mean arterial pressure (MAP) at T5 in control group and D1 group were significantly higher that in D2 group and D3 group, and there were statistical differences (P<0.05). The heart rate at T1-T5 in D1-D3 group were significantly lower than that in control group, and there were statistical differences (P<0.05). The spontaneous breathing recovery time, call of eye-opening time, extubation time in D1 - D3 group were longer than those in control group, but there were no significant differences (P>0.05). The VAS 15 min after extubation in D1 - D3 group were significantly lower than that in control group: (3.7 ± 0.3), (3.1 ± 0.4) and (3.0 ± 0.5) scores vs. (6.2 ± 0.6) scores, and there were statistical differences (P<0.05). The Ramsay sedation scores in D1 - D3 group were significantly higher than that in control group:(2.5 ± 0.2), (2.7 ±0.2) and (5.3 ± 0.3) scores vs. (1.4 ± 0.3) scores. Moreover, Ramsay sedation score in D3 group was significantly higher than that in D1 group and D2 group, and Ramsay sedation score in D2 group was significantly higher than that in D1 group. There were statistical differences (P<0.05). Four and 2 patients occurred nausea vomiting respectively in control group and D1 group within 24 h after operation. Conclusions Dexmedetomidine combined with propofol and remifentanil TCI can maintain hemodynamic stability and improve anesthesia recovery quality.

Objective To test the protective effect of a new Ringer's malate solution on intestine's apoptosis caused by hemorrhagic shock in rats.Methods Forty-eight Sprague-Dawley male rats, weighing 280-320 g, were randomly assigned into four groups: sham shock group (group SS), normal saline group (group NS), Ringer's lactate group (group RL) and Ringer's malate (group RM), n=12 each.The group SS was served as control group, the other groups were subjected to 60 min of hemorrhagic shock followed by crystalloid resuscitation.Those rats were sacrificed 3 h after resuscitation.Intestinal tissue was harvested to detect Bcl-2/Bax protein level, the bioactivity of superoxide dismutase (SOD) and malondialdehyde (MDA) level.The level of intestinal cell apotosis was measured using TUNEL method and apoptosis index was calculated.The intestinal histopathology was examined.Results Compared with group SS, the expression of Bcl-2 and the bioactivity of SOD were lower, the level of Bax protein, MDA and apoptotic index were higher in groups NS, RL and RM (P<0.05).Compared with groups NS and RL, the expression of Bcl-2 and the bioactivity of SOD was higher, the level of Bax protein, MDA and apoptotic index were lower in group RM (P<0.05).Histopathological examination showed that group RM was better than group NS and group RL.Conclusion Ringer's malate alleviated intestinal apoptosis caused by hemorrhagic shock in rats.The study suggests that Ringer's malate solution could be a potential new therapeutic agent for fluid resuscitation.

Objective To compare the degree of liver injury during resuscitation with different crystalloid solutions in a rat model of hemorrhagic shock.Methods Forty-eight SPF healthy male SpragueDawley rats,aged 7-9 weeks,weighing 280-320 g,were assigned into 4 groups (n=12 each) using a random number table:sham operation group (group S),normal saline group (group NS),Ringer's lactate solution group (group RL) and Ringer's malate solution group (group RM).Hemorrhagic shock was induced by withdrawing blood from the right internal jugular vein until mean arterial pressure was reduced to 35-45 mmHg which was maintained for 1 h.The internal jugular vein and artery were cannulated after anesthetization,but no animals were subjected to hemorrhage in group S.The crystalloid solution (2 times the volume of blood loss) was infused intravenously over 30 min starting from 1 h of shock.The animals were resuscitated with 0.9％ sodium chloride solution in group NS,with Ringer's lactate solution in group RL,and with Ringer's malate solution in group RM.Mean arterial pressure was continuously monitored and recorded during the experiment.Before shock (T1),at 1 h of shock (T2) and at 4 h after resuscitation (T3),blood samples were collected from the right internal jugular vein for determination of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) concentrations by enzyme-linked immunosorbent assay.Rats were sacrificed at T3,and livers were removed for measurement of malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in liver tissues (using colorimetric method) and for examination of pathological changes of liver tissues (with light microscope).Results Compared with group S,the serum ALT and AST concentrations at T2.3 and SOD activity and MDA content at T3 were significantly increased in NS,RL and RM groups (P＜0.05).Compared with group NS or group RL,the serum ALT and AST concentrations were significantly decreased,the SOD activity was increased,and the MDA content was decreased at T3 (P＜0.05),and the pathological changes of liver tissues were significantly attenuated in group RM.Conclusion Ringer's malate solution produces better efficacy than normal saline and Ringer's lactate solution when used for resuscitation and mitigating liver injury in a rat model of hemorrhagic shock.

Objective To study the effects of two types of crystalloids on postoperative inflam-matory reaction during the process of cesarean section.Methods Sixty patients undergoing cesarean section were randomly divided into Ringer lactate solution group (RL)and Ringer acetate solution group (RA)with 30 cases in each group.Before anesthesia,10 ml/kg crystal solution was infused, the infusion rate was 1 5-20 ml·kg-1 ·h-1 .The patients were performed epidural anesthesia in left lateral position.Crystal solution was infused to maintain the blood pressure during the operation.Ve-nous blood was drawn at the beginning of the operation (T1 ),the end of the operation (T2 ),four hours after operation (T3 ),twenty-four hours after operation (T4 )in order to measure the blood plasma value of IL-6,TNF-α,CRP.Results The blood plasma value of IL-6,TNF-α,CRP had no significant differences at T1 ,T4 ;but the value of group RA was significantly higher than that of group RL (P <0.05)at T2 ,T3 .Conclusion Ringer acetate solution causes more significant postop-erative inflammatory cytokine release than Ringer lactate solution does during the process of cesarean section.

Objective To evaluate the immunoprotection by the inactivated whole bacteria(IWB) of Stenotrophomonas maltophilia K279a in mice.Methods Mice were immunized by inactivated whole bacteria of S.maltophilia K279a made from formaldehyde.When the indicated the antibody titer of the mice reached the require level, the protective effect of the IWB was evaluated by performing the opsonophagocytic killing test in vitro and the poison attack experiments in vivo. Results It was found that IgG in serum of the immunized mice measured by ELISA was significantly increased after the second immune enhancement, and antiserum in vitro had strong phagocytic effect.Meanwhile, immunoprotection of the immunized groups was also significantly increased when challenged by S.maltophilia K279a.Conclusion Effective humoral immune response can be predominantly induced by the inactivated whole bacteria of S.maltophilia K279a, providing protection against challenge by S.maltophilia K279a in BALB/c mice.

Objective To explore the associations between vitamin D receptor ( VDR) Fok- Ⅰ and Apa- Ⅰ polymorphisms and myasthenia gravis (MG) in Chinese Han population.Methods Polymorphisms of VDR Fok- Ⅰ and Apa-Ⅰ were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.The frequencies of genotypes and hyplotypes were compared among 286 normal controls and 267 MG patients in different subgroups classified by gender,age of onset,presence of thymoma,and Osserman classification sat maximal severity in the follow-up.The association between the genotypes and maximal severity of MG and short-term glucocorticoid treatment were also investigated.Results There were no significant differences in frequencies of genotypes and hyplotypes of both Fok-Ⅰ and Apa-Ⅰ between MG group and control group,and among subgroups of MG.The Fok- Ⅰ showed no statistical difference between the patients with better and less improvement after short-term treatment of glucocorticoid.The frequency of Apa-Ⅰ alleles in the patients with better improvement (55/186,29.6% ) significantly differed from the less improved group ( 7/48,14.6%,OR = 2.46,95% CI 1.04-10.43,x2 = 4.400,P = 0.036).The patients with the genotype A A/Aa were more likely to improve better after the treatment(48/93,51.6%) than in the worse group(7/24,29.2%,OR =2.59,95% CI 0.98-14.60,x2 =3.858,P= 0.049).Conclusions Alleles and genotypes of VDR-Fok- Ⅰ and Apa-Ⅰ were not found to be related with MG onset and severity.MG patients with VDR-Apa-A allele may have better improvement short-term treatment of glucocorticoid.

OBJECTIVETo screen for genomic copy number variants (CNVs) in a fetus with one sibling affected with Prader-Willi syndrome using single nucleotide polymorphism (SNP) array.

METHODSThe fetus and its parents were subjected to chromosomal karyotyping and SNP array analysis.

RESULTSA 5p15.33 microdeletions was identified in the fetus and its phenotypically normal mother with a size of 344 kb (113 576 to 457 213). The father was normal for both testing. Analysis of literature and CNVs database indicated the above CNV to be variant of unclear significance. The couple decided to continue with the pregnancy and gave birth to a healthy boy at full-term. No abnormalities were found during the follow-up.

CONCLUSIONThis study may provide further data for the phenotype-genotype correlation of 5p15.33 microdeletion, which differs from Cri du Chat syndrome.

OBJECTIVETo screen for genomic copy number variants (CNVs) in a fetus with cardiac abnormalities and intrauterine growth retardation through single nucleotide polymorphism microarray (SNP array) and karyotyping analysis.

METHODSThe fetus and its parents were subjected to conventional G banding and SNP-array analysis. The results were confirmed with fluorescence in situ hybridization (FISH).

RESULTSG-banding analysis showed that the fetus has a karyotype of 47,XX,+mar. The father has a karyotype of 46,XY,t(4;18) (p15.2q11.2), while the mother showed a normal karyotype. SNP-array detected two microduplications at 18p11.32q11.2 (20.5 Mb) and 4p16.3p15.2 (24.7 Mb) in the fetus. The supernumerary marker chromosome carried by the fetus has derived from the balanced translocation carried by its father. The result was confirmed by FISH.

CONCLUSIONBased on the two microduplications, the fetus was diagnosed as Wolf-Hirschhorn syndrome in conjunction with Edward syndrome. Verification of the origin of the supernumerary marker chromosome by SNP-array has provided a basis for prenatal genetic diagnosis.

OBJECTIVETo explore the genetic etiology of two fetuses with Dandy-Walker malformation using single nucleotide polymorphism microarray (SNP-array).

METHODSThe fetuses and their parents were subjected to G banding karyotype analysis. The fetuses were also subjected to SNP-array analysis.

RESULTSThe parents of both fetuses showed a normal karyotype. One fetus has a 46,X,?i(X)(q10), while for another conventional cell culture has failed. SNP-array showed that one fetus carried a 6p25.3p25.2 microdeletion, and another carried a Xp22.33p22.2 deletion and a Yq11.221q11 duplication. The abnormal fragments have involved FOXC1, SHOX and STS genes, which are associated with Dandy-Walker malformation.

CONCLUSIONAlteration of 6p25.3p25.2, Xp22.33p22.2 copy numbers probably underlies the Dandy-Walker syndrome in the fetuses. The disorder may be attributed to abnormal expression of FOXC1, SHOX, and STS genes. SNP-array can provide an important supplement for prenatal diagnosis.
