Objective To evaluate the efficacy and safety of combination therapy of oxaliplatin and S-1 vs oxaliplatin and docetaxel for advanced gastric cancer (AGC)patients.Methods From April 201 1 to Janu-ary 201 3,62 cases of AGC were collected in the Fifth People′s Hospital of Qinghai Province.All cases were randomly divided into group A (31 cases)and B (31 cases)by random number table.In group A,oxaliplatin plus S-1 was administered,and in group B,oxaliplatin plus docetaxel was applied.The response rate (RR), time of diseases controlled rate (DCR),progression-free survival (PFS),overall survival (OS)and adverse reactions of the two groups were observed and compared.Results There were no statistically differences between group A and group B in RR (48.4% vs 54.8%),DCR (67.7% vs 77.4%),mPFS (5.4 months vs 6.2 months),mOS (9.0 months vs 9.8 months),and the statistical values were as follows:χ2 =0.26,P =0.71 1 ;χ2 =0.73,P =0.393;χ2 =0.51 ,P =0.473;χ2 =0.03,P =0.829.The incidence of degrees Ⅰ-Ⅱperipheral neuropathy (9.7% vs 22.6%),nausea and vomiting (1 2.9% vs 32.3%)in group A were signifi-cantly lower than those in group B (χ2 =5.78,P =0.002;χ2 =4.63,P =0.01 6).Conclusion Both the two chemotherapies are similar in therapeutic effect for patients with AGC.Oxaliplatin plus S-1 treatment may be better than oxaliplatin plus docetaxel in the tolerance of patients.

BACKGROUND: Breast augmentation with polyacrylamide hydrogel injection has been used nearly for a decade in some Chinese medical therapy units. More patients need to be removing injections or a second augmentation due to complications. More attention should be paid for possibility of complications concomitant with breast malignant tumor. OBJECTIVE: Two cases of breast invasive duct carcinoma diagnosed after removing injection were analyzed retrospectively in order to increase the importance of detection rate of breast malignant tumor. METHODS: Two cases in all 41 assembled patients which were removed polyacrylamide hydrogel injections from 82 breasts were diagnosed with invasive carcinoma. The characteristics of medical history, physical diagnosis, image diagnosis and pathological examination were analyzed retrospectively. RESULTS AND CONCLUSION: The detection rate of breast malignant tumor should arise more attention in patients requiring removal of polyacrylamide hydrogel injection. The following aspects should be emphasized such as the comprehensive analysis for the results of physical diagnosis and image diagnosis, tumor-free operation with more samples from suspicious nodules and frozen pathological examination. The principles of cancer surgery should be followed in pathological diagnosed cases in case of iatrogenic metastasis and spread of breast malignant tumor.

Fourteen compounds were isolated from the ethyl acetate fraction of 90% EtOH extracts of the dried fruits of Alpinia oxyphylla by silica gel, MCI, RP-18, Sephadex LH-20, TLC and semi-preparative HPLC column chromatography. Their structures were identified by HR-ESI-MS, UV, IR, NMR, ECD and X ray single crystal diffraction spectroscopic data as: (2R,5R,7R,10S)-2,7-dihydroxyl-eudesmane-3(4),11(12)-diene (1), α-rotunol (2), diketone I (3), (1S,4S,5R,7S)-1-hydroxyl-eremophilane-9(10),11(12)-diene-8-one (4), cyperusol A₁ (5), (6R,9S,10S)-10-hydroxyl-11,12,13-trinor-cadinane-4(5)-ene-3-one (6), (2E,4E)-6-hydroxy-2,6-dimethylhepta-2,4-dienal (7), oxyphyllacinol (8), yakuchinone A (9), (5R)-5-hydroxy-1,7-diphenylhept-3-heptanone (10), (5S)-5-hydroxy-7-(4″-hydroxyphenyl)-1-phenylhept-3-heptanone (11), (5S)-5-hydroxy-7-(4″-hydroxyl-3″-methoxyphenyl)-1-phenyl-3-heptanone (12), 7-(4″-hydroxy-3″-methoxyphenyl)-1-phenyl-3,5-heptadione (13), bis-(2-ethylhexyl) terephthalate (14). Compounds 1-6 were sesquiterpenoids in which compound 1 is a new eudesmane sesquiterpenoid and compound 7 was a monoterpenoid. Compounds 8-13 were diarylheptanoids, and compounds 2-6 and 14 were isolated from A.oxyphylla for the first time. The experiments on H₂O₂ induced SH-SY5Y cells showed that compounds 2, 6, 7, 12 and 13 had neuroprotective effects at low and medium concentrations. In particular, compound 6 showed obvious neuroprotective effect at low, medium and high concentrations whose cell viability was higher than that of the positive control.

Objective To compare the effect of injection with botulinum toxin type A (BTX-A) before serial casting with BTX-A injection alone for the treatment of spastic equinus in children with cerebral palsy (CP).Methods Sixty patients were divided into an experimental group and a control group with 30 patients in each.Those io the experimental group received a BTX-A injection followed by serial casting,while the controls received BTX-A only.Before treatment and 1 month,3 months and 6 months after treatment,the dorsiflexion range of motion (ROM)of the ankle recorded while the knee in flexion and extension were measured,and gait was evaluated with an observational gait scale.Results Before treatment there was no significant inter-group difference in any of the 3 outcome measures.At 1 montb,3 months and 6 months after treatment,there were significant inter-group differences in all 3 measures,and also significant differences compared with before treatment in both groups.Conclusion Lower muscle tone,greater ankle mobility and better gait patterns can be promoted in CP children with spastic equinus using serial casting combined with BTX-A injection.The improvements may last longer than those after BTX-A injection alone.
