Objective To investigate the clinical significance of gamete intrafallopian transfer (GIFT) under laparoscope. Methods The gonadotropin was adopted to induce superovulation and the spermatic fluid was managed with the swim-up method. After oviums were dislodged by puncture under laparoscope, gametes were transplanted by intubating the fallopian tube. Results Among a total of 19 patients, 4 were pregnant, the pregnancy rate being 21.1% (4/19). Three women had a delivery at term and 1 had an abortion. No serious complications were seen. Of the 15 unfertilized patients, normal pregnancy was observed within 6 months after surgery in 5 patients, the circle pregnancy rate being 5.6% (5/89). Conclusions GIFT under laparoscope is a practical assisted reproductive technique (ART) that may achieve a relatively high pregnancy rate. Some other pelvic diseases resulting in infertility can be treated simultaneously, which contributes to natural fertilization in the future.

Objective To investigate the effects of different acupuncture therapies on serum branched-chain amino acids (BAC and free tryptophan (F-Trp) in high-intensity military training soldiers. Methods Ninety healthy soldiers were randomly allocated to groups A, B and C, 30 soldiers each. Group A received treatment with electroacupuncture at Zusanli; group B, treatment by cupping on Zusanli;group C, no treatment. The three groups did a high-intensity 5 km running exercise after two weeks of treatment. Serum BACC and F-Trp contents were measured in the three groups before and at the end of treatment and at five days after treatment. Results It can be seen from table 2 that there were no statistically significant pre-treatment differences in serum BACC and F-Trp contents between the three groups of soldier subjects (P>0.05); there were statistically significant pre-/post-treatment differences in serum BACC and F-Trp contents in the three groups of soldier subjects (P＜0.05). There was a statistically significant post-treatment difference in serum BACC content between group A or B and group C (P＜0.05). There was a statistically significant difference in serum F-Trp content between group A or B and group C at the end of treatment and at five days after treatment (P＜0.05). Conclusion Acupuncture therapy can effectively improve bodily anti-fatigue ability and reduce high-intensity exercise induced muscular injury in military training soldiers.

Objective To study the dosimetric characteristics of flattened and flattening filter free (FFF) beams with 6 MV and 10 MV photon energy using a novel dual-energy medical linear accelerator (Elekta Versa HDTM),to identify the dosimetric characteristics and advantages of FFF beams,and to provide a basis for their clinical application.Methods The percentage depth dose (PDD),profiles/dose rate of off-axis ratio (OAR),field size,penumbral width,dose out of the fields,collimator scatter factor (Sc),and total scatter factor (Sc,p) were compared between flattened and FFF beams.Results (1) After beam energy matching,the FFF beams had the same beam energy with the flattened beams.The matching error of PDD at a depth of 10 cm was less than 1％ between fields.(2) The FFF beams had a smaller variation in dose rate of OAR with the depth than the flattened beams.(3) The FFF beams had smaller variations in field size and penumbral width than the flattened beams.Moreover,the penumbral width of the FFF beams increased with the increasing field size or depth.The FFF beams had a lower dose out of the fields than the flattened beams.(4) The FFF beams had smaller variations in Sc and Sc,p with the field size and depth than the flattened beams.Conclusions Removal of the flattening filter can substantially improve the dose rate,shorten radiotherapy time,and reduce leakage and scattering of the head.The dosimetric advantages make the FFF beams appropriate for clinical treatment.

Objective To evaluate the immune effects of bivalent inactivated rotavirus vaccine (IRV) and investigate the viability of development of bivalent IRV.Methods Firstly,bivalent IRV was prepared by mixing G1 IRV and G3 IRV with equal amount,G1 IRV and G3 IRV as monovalent control,PBS as negative control.Secondly,those vaccines were vaccinated to the mice by intramuscular injection.Then,to evaluate the immune effects of bivalent IRV,the levels of serum or fecal rotavirus specific IgG and IgA were assessed by ELISA,the levels of serum neutralized antibody were measured by microneutralization assay,the number of IFN-γ or IL-4 secreting cells were analyzed by ELISPOT assay.Results Compared to negative control group,bivalent IRV induced the higher levels of serum and fecal G1 and G3 rotavirus specific antibody.It was found that there were no significant differences for the levels of serum IgG and IgA,fecal IgG and IgA,serum neutralized antibody between induced by bivalent IRV and induced by G1 type monovalent vaccines ; but there were significantly increase for the levels of serum IgG (t =2.691,P＜0.05) and serum neutralized antibody (t =2.561,P＜0.05) between induced by bivalent IRV and induced by G3 monovalent vaccines,there were no significant differences for other antibodies between induced by bivalent IRV and induced by G3 monovalent vaccines.At the same time,compared to negative control group,bivalent IRV induced significantly increase in the number of IFN-γ or IL-4 secreting cells in spleen lymphocytes.It was found that there were no significant differences for the number of IFN-γ or IL-4 secreting cells stimulated by G1 rotavirus between bivalent IRV and G1 monovalent vaccines; but there were significantly increase for the number of IL-4 secreting cells (t =2.327,P＜0.05) stimulated by G3 rotavirus between bivalent IRV and G3 monovalent vaccines,there were no significant differences for the number of IFN-γ secreting cells stimulated by G3 rotavirus between bivalent IRV and G3 type monovalent vaccines.Conclusion The bivalent IRV can induce effective immune response,in which there were no inhibitory interference between the components of bivalent IRV,which provided the experimental basis for the development of bivalent IRV.

Objective· To investigate the prospective value of early postoperative PI-APD in children with hydronephrosis.Methods· Data of children with hydronephrosis who underwent pyeloplasty in Xinhua Hospital,Shanghai Jiao Tong University School of Medicine between Jan 2012 to Nov 2015 was collected.PI-APD was divided into 3 categories (≤ 19％,19％＜PI-APD＜40％ and ≥ 40％).The relationship between PI-APD value and the degree of renal function (DRF) and dilation recovery after surgery was analyzed.Results· There were 360 children with hydronephrosis.The median follow-up was 20 months.The PI-APD value (3 months after pyeloplasty) was positively correlated with the degree of DRF recovery (r=0.631,P=0.000).Five patients received redo-pyeloplasty.PI-APD of all these patients was ＜19％.Conclusion· PI-APD is a new feasible ultrasound parameter in pyeloplasty followup.PI-APD ≥ 40％ at the first post-operative visit predicts pyeloplasty success.PI-APD ≤ 19％ indicates close follow-up after operation.PI-APD can also help select children at high risk for repeat intervention after pyeloplasty.

ObjectiveTo investigate the effects of morin treatment on bone metabolism and bone mass in aged rats， and to clarify the possible mechanism. MethodsTen young female Sprague-Dawley rats （3 months old） and 20 old female Sprague-Dawley rats （24 months old） were randomly divided into three groups： Control group （CON， 10 young rats）； Model group （MOD， 10 young rats）； 10 old rats and SangHuangSu Group （SSS， 10 old rats）. During the experiment， the SSS group received intraperitoneal injection of morin （10 mg / kg） daily. The treatment lasted for 12 weeks. After treatment， Micro-CT， HE stained sections， serological tests and Western blot were used to observe the treatment effect and possible mechanism. ResultsAfter 12 weeks of treatment， compared with MOD group， the number and density of bone trabeculae in SSS group were significantly improved. The BMD， Conn. D， Tb. N， Tb.Th and Tb.Sp of the left femur in the SSS group were significantly better than those in the MOD group（P <0.05）. After 12 weeks of treatment， the levels of CTX-1， osteocalcin， TRACP-5b and PINP in SSS group were significantly lower than those in MOD group（P <0.05）. Compared with the MOD group， the ERK1/2-p38 signal pathway was significantly inhibited and the levels of ERK1/2 and p38 were significantly decreased in the SSS group（P <0.05）. ConclusionMorin pigment mediates the protective effect on the bones of aged rats by inhibiting the ERK1/2-p38 signaling pathway and reducing bone turnover.
