Objective To investigate the clinical and pathological features of pure type mitochondrial myopathy.Methods Clinical manifestations and pathological features of biopsied muscle specimens were summarized retrospectively in 9 cases of pure mitochondrial myopathy. 6 of them were followed up on the purpose of prognostic analysis.Results 9 cases of pure mitochondrial myopathy were clinical characterized by exclusive skeletal muscle involvement and fluctuating proximal muscle weakness. Extraocular muscles were spare. Most patients had moderately increased creatine phosphokinase level (539～2 913U/L). Electromyography examination showed myogenic changes in 6 cases and neurogenic in 3 cases. Pathologically, 8 cases had typical ragged red fibers (RRF) accounting for 5% to 60%. Mitochondrial intracristal inclusion bodies were observed by electron microscope in the patient with atypical RRF. Focal cytochrome C oxidase (COX) deficiency was seen in 4 cases and total deficiency in 2 cases. To a certain degree, the percentage of RRF was parallel to muscle weakness. Following-up data from 6 patients showed that symptoms had improved in 5 patients after treatment with vitamin B, vitamin E, CoQ 10 and inosine. One had a sudden death with unknown reason.Conclusion Pure mitochondrial myopathy may be a distinct subset of mitochondrial diseases that preferentially affects trunk and proximal muscles,Pathological charactoristic had typical RRF and COX deficiency,and RRF is related to patient's condition.It has relative chronic process and benign prognosis.

Objective: To study the accuracy of MRI-CT image registration in order to find a more effective method of image fusion and a standard for the evaluation of post-operative intra-cranial tumor radiotherapy.Methods: Twenty-four patients with intra-cranial tumor underwent MR T1-weighed sequence and post-operative location CT scan under the same location condition.The trans-axial MR T1-weighed sequence and CT image were registered and the correlation between registration scores and errors was analyzed by the method of Tris-Axes Landmark.The linear registration errors were observed in the three-dimensional space of every patient.Results: An improved linear correlation was found between registration scores and errors(r=-0.985,y=-0.551 3x+5.351 4).The registration met the clinical standard when the scores exceeded 6.61.Conclusion: Tris-Axes Landmark is a preferable registration method to be used in clinical radiotherapy for rapid and precise evaluation of MRI-CT image registration accuracy.

This investigation describes a new precise, sensitive and accurate stereoselective RP-HPLC method for determination of the enantiomers of a novel alpha- and beta-receptor blocking agent, 1-[4-(2-methoxyethyl) phenoxy]-3-[[2-(2- methoxyphenoxy) ethyl]amino]-2-propanol (TJ0711), in rat plasma. GITC was used for precolumn derivatization of TJ0711 enantiomers. Enantiomeric resolution was achieved on a Eurospher-100 C18 column (250 mmx4.6 mm ID, 5-mum particle size), with UV detection at 255 nm, and the mobile phase consisted of acetonitrile and water (58:42, v/v) containing 0.02% glacial acetic acid (v/v). Using the chromatographic conditions described, TJ0711 enantiomers were well resolved with mean retention time of 10.2 and 11.5 min, respectively. Linear response (r>0.999) was observed over the range of 0.125-12.5 mug/mL of TJ0711 hydrochloride enantiomers. The mean relative standard deviation (RSD%) of the results of within-day precision was [Symbol: see text] 10%. The proposed method was found to be suitable and accurate for the quantitative determination of TJ0711 enantiomers in rat plasma, and it can be used in pharmacokinetic studies.

Objective:To investigate the variations o f mitochondrial D-loop region in gastric cancers. Methods:The D-loop region of 12 gastric cancers together with th e adjacent normal tissues were amplified by PCR and sequenced. Results: Among the 12 cases,16 mutations and 28 polymorphisms were identified with the mutations rate of 50%.There were 3 new polymophisms which we re not reported previously in the GeneBank among the 28 polymorphisms. Conclusion:We think that the mitochondrial DNA D-loop region is a highly polymorphric and mutable region and the mutation rate is relatively high in patients with gastric cancer.

Objective·To identify the relationship between the estimated fetal weight (EFW) discordance and birth weight (BW) discordance, and evaluate the accuracy of ultrasonography in predicting birth weight discordance (△BW) of twin pregnancy. Methods·The ultrasound was used to detect the growth of twins at different gestational weeks and the data were analyzed to compare the difference between EFW discordance (△EFW) and ?BW. Results·About 15.9 percent of twins (totally 277 cases) had severe △BW (△BW ≥20%) in our study, and the percentages of dichorionic-diamniotic twin (DCDA) and monochorionic-diamniotic twin (MCDA) were 68.2% and 31.8%, respectively (P>0.01). Compared with △EFW in other gestational weeks,△EFW last time before parturition was most consistent of △BW. Furthermore, the negative predictive value of MCDA was highest (94%) at 22-24 gestational weeks. Conclusion·Twin △BW was relatively better predicted by △EFW last time before parturition. Twin pregnancy without severe △EFW (△EFW<20%), especially MCDA with △EFW<20% at 22-24 weeks, had low probability of selective intrauterine growth restriction in the future.

Objective To compare the oil yield of celery seeds and the contents of 3-n-butylphthalide and the total phthalocyanine lactones of celery seed oil extracted by different methods. Methods Three routine extraction methods involving organic solvent extraction, Soxhlet extraction, steam distillation extraction, as well as subcritical extraction method and supercritical fluid extraction method were used to extract the celery seed oil. The contents of 3-n-butylphthalide and total phthalocyanine lactones were respectively detected by high performance liquid chromatography(HPLC) and ultraviolet visible spectrophotometry. Results The ranges of oil yield and the contents of 3-n-butylphthalide and total phthalocyanine lactones of celery seed oil extracted by different methods were 0.30%-20.02%, 1.40%-10.13%, 4.74%-17.65%, respectively, indicating obvious differences. Conclusion With R134a and butane as the solvents, the subcritical extraction method is better than other extraction methods for the extraction of 3-n-butylphthalide. With dimethyl ether as the solvent, the subcritical extraction method is the best for the extraction of total phthalocyanine lactones.

Objective:To analyze the factors affecting lymph node failure pattern after radiotherapy/chemotherapy in esophageal squamous cell carcinoma without initial clinical metastasis. Methods:A total of 263 patients, who were diagnosed as thoracic esopha-geal carcinoma from January 2002 to December 2009, were included in this retrospective study. Factors affecting lymph node failure pattern with general clinical data and tumor local factors were analyzed. Results:Among the 263 esophageal cancer cases, 31 (11.8%) had lymph node metastasis after treatment, including 18 cases of simple lymph node metastasis and 13 other cases of lymph node metas-tasis with esophageal and other organ metastasis or recurrence. The numbers of cases for lymph node metastasis in the upper, middle, and lower thoracic esophagus were 11 (13.3%), 13 (10.1%), and 7 (13.7%), respectively. Univariate analysis showed that recent cura-tive effect, length of tumor on X-rays, maximum tumor diameter, and tumor volume were the significant factors associated with lymph node metastasis (χ2=7.597, 9.717, 5.361, and 4.815;P=0.006, 0.002, 0.021, and 0.028). Logistic regression analysis results showed that recent curative effect and length of tumor on X-rays were independent significant factors (P=0.004 and 0.026). Conclusion:Recent cu-rative effect and length of tumor on X-rays were the significant factors associated with lymph node failure pattern after radiotherapy/chemotherapy in esophageal squamous cell carcinoma without initial clinical metastasis.
