ObjectiveTo observe the clinical efficacy of qi-blood-supplementing needling in treating the incipient leukopenia after chemotherapy for breast cancer.MethodSeventy-eight patients with incipient leukopenia after chemotherapy for breast cancer were recruited and randomized into a control group (38 cases) and a treatment group (40 cases). The control group was intervened by medications for increasing white blood cell (WBC) count, while the treatment group was by qi-blood-supplementing needling plus the medication. The therapeutic efficacies were evaluated at the end of the intervention.ResultThe WBC counts increased significantly in both groups after treatment (P<0.01), and the count in the treatment group was significantly higher than that in the control group (P<0.05). The total effective rate was 95.0% in the treatment group versus 89.5% in the control group, and the therapeutic efficacy of the treatment group was superior to that of the control group (P<0.05). The treatment group was also better than the control group in improving symptoms including poor appetite, fatigue, pale complexion, and lassitude (P<0.05,P<0.01).ConclusionFor patients with incipient leukopenia after chemotherapy for breast cancer, qi-blood-supplementing needling plus medication for increasing WBC count can up-regulate the WBC count and improve the symptoms due to qi-blood deficiency.

Objective To explore the effects of application of laparoscopic simulators in teaching of plastic surgery. Methods 10 plastic surgeons and 20 standardized training surgical residents with 2 to 4 years' experience were tested about their proficiency in moving beans, pinching, suturing and tying by timing and counting. After they were trained with laparoscopic simulators 3, 6, 9 times with each time for 90 min, tests were taken. SPSS 19.0 was used to make single factor variance analysis of the related data or conduct q test. Result There was significant difference before and after the residents' training of moving beans, pinching, suturing and tying (P<0.05). Less time to finish the operation was needed after training, but after training for 6 times or 9 times, there was no significant difference in operation time (P >0.05). Conclusion Application of laparoscopic simulator training can significantly improve the operation skills of the novices with some clinical experience in the short term, which is conducive to the endoscope assisted breast augmentation surgery, and is worthy of promotion.

A novel method was developed for the rapid determination of multi-indicators in corni fructus by means of near infrared (NIR) spectroscopy. Particle swarm optimization (PSO) based least squares support vector machine was investigated to increase the levels of quality control. The calibration models of moisture, extractum, morroniside and loganin were established using the PSO-LS-SVM algorithm. The performance of PSO-LS-SVM models was compared with partial least squares regression (PLSR) and back propagation artificial neural network (BP-ANN). The calibration and validation results of PSO-LS-SVM were superior to both PLS and BP-ANN. For PSO-LS-SVM models, the correlation coefficients (r) of calibrations were all above 0.942. The optimal prediction results were also achieved by PSO-LS-SVM models with the RMSEP (root mean square error of prediction) and RSEP (relative standard errors of prediction) less than 1.176 and 15.5% respectively. The results suggest that PSO-LS-SVM algorithm has a good model performance and high prediction accuracy. NIR has a potential value for rapid determination of multi-indicators in Corni Fructus.

OBJECTIVETo study the diagnosis and the differential diagnosis of nodular lymphocyte-predominant Hodgkin's lymphoma (NLPHL).

METHODS245 cases of Hodgkin's lymphoma (HL) diagnosed between 1980 and 2000 from 3 hospitals in Guangzhou were reviewed. Four cases of NLPHL were confirmed according to the WHO classification of lymphoid neoplasms. Among the other 3 cases of NLPHL, 2 collected from other clinical centers and 1 from Fudan University Cancer Hospital. Immunohistochemistry (IHC) were performed on paraffin sections through SP technique using a panel of markers to define the large neoplastic cells (CD45, CD20, CD15, CD30 and vimentin) as well as the non-neoplastic background cells (CD3, CD20, CD45RO, CD57, CD68 and TIA-1).

RESULTSSeven patients with NLPHL were 4 males and 3 females, age 29 to 70 years, average 43.8 years. All patients had lymphadenopathy. Histologically, in NLPHL, instead of the structure of normal lymph nodes, the tumor tissue became nodular in architecture. Characteristic lymphocytic and histiocytic (L&H) cells with scant cytoplasm and large multilobulated nuclei distributed among a predominant population of small lymphoid cells. The large cells exhibited a CD45+, CD20+, but CD15-, CD30- and vimentin-phenotype. The background cellularity was relatively rich in B cells and the majority of T-cells infiltrated were CD57(+) cells. TIA-1+ cells were few.

CONCLUSIONSNLPHL can be diagnosed according to the morphologic and immunophenotypic features rather than by morphology alone. It is important to distinguish this tumor from its morphologic mimics, such as lymphocyte-rich classical Hodgkin's lymphoma (LRCHL) and T-cell rich B-cell lymphoma (TCRBCL). The immunophenotype of neoplastic cells and background cells are the helpful criteria for the differential diagnosis.

OBJECTIVE: To screen for mutations of fragile X mental retardation 1 (FMR1) gene during early and middle pregnancy and provide prenatal diagnosis for those carrying high-risk CGG trinucleotide expansions. METHODS: Peripheral blood samples of 2316 pregnant women at 12 to 21(+6) gestational weeks were collected for the extraction of genomic DNA. CGG repeats of the FMR1 gene were detected by fluorescence PCR and capillary electrophoresis. Genetic counseling and prenatal diagnosis were provided for 3 women carrying the premutations. RESULTS: The carrier rate of CGG repeats of the FMR1 gene was 1 in 178 for the intermediate type and 1 in 772 for the premutation types. The highest frequency allele of CGG was 29 repeats, which accounted for 49.29%, followed by 30 repeats (28.56%) and 36 repeats (8.83%). In case 1, the fetus had a karyotype of 45,X, in addition with premutation type of CGG expansion of the FMR1 gene. Following genetic counseling, the couple chose to terminate the pregnancy through induced labor. The numbers of CGG repeats were respectively 70/- and 29/30 for the husband and wife. In case 2, amniocentesis was performed at 20 weeks of gestation. The number of CGG repeats of the FMR1 gene was 29/-. No abnormality was found in the fetal karyotype and chromosomal copy number variations. The couple chose to continue with the pregnancy. Case 3 refused prenatal diagnosis after genetic counseling and gave birth to a girl at full term, who had a birth weight of 2440 g and no obvious abnormality found during follow-up. CONCLUSION Pregnant women should be screened for FMR1 gene mutations during early and middle pregnancy, and those with high-risk CGG expansions should undergo prenatal diagnosis, genetic counseling and family study.

OBJECTIVE: To report on a case of Smith-Magenis syndrome (SMS) due to a rare small-scale deletion. METHODS: Muscle samples from the the third fetus was collected after the in Medical history and clinical data of the patient were collected. The child and his parents were subjected to chromosome karyotyping analysis, multiplex ligation-dependent probe amplification (MLPA) and copy number variation sequencing (CNV-seq). RESULTS: The child was found to have a normal karyotype. MLPA and CNV-seq detection showed that he has harbored a 1.22 Mb deletion and a 0.3 Mb duplication in the 17p11.2 region. Neither of his parents was found to have similar deletion or duplication. CONCLUSION The child was diagnosed with SMS due to a rare 1.22 Mb deletion in the 17p11.2 region, which is among the smallest deletions associated with this syndrome.

OBJECTIVE: To detect potential mutations of the PKHD1 gene in two pedigrees affected with infantile polycystic kidney disease. METHODS: Clinical data and peripheral venous blood samples were collected from the probands and their parents as well as fetal amniotic fluid cells. Genome DNA was extracted from the peripheral blood samples and amniotic fluid cells. Exons 32 and 61 of the PKHD1 gene were amplified with PCR and subjected to direct sequencing. RESULTS: The proband of pedigree 1 was found to carry c.4274T>G (p.Leu1425Arg) mutation in exon 32 and c.10445G>C (p.Arg3482Pro) mutation in exon 61 of the PKHD1 gene, which were inherited from her father and mother, respectively. The fetus has carried the c.4274T>G (p.Leu1425Arg) mutation. In pedigree 2, the wife and her husband had respectively carried a heterozygous c.5979_5981delTGG mutation and a c.9455delA mutation of the PKHD1 gene. No chromosomal aberration was found in the umbilical blood sample, but the genetic testing of their fetus was failed. Based on software prediction, all of the 4 mutations were predicted to be pathogenic. CONCLUSION PKHD1 c.4274T>G (p.Leu1425Arg), c.10445G>C (p.Arg3482Pro), c.5979_5981delTGG and c.9455delA were likely to be pathogenic mutations. The results have facilitated genetic counseling and prenatal diagnosis for the two pedigrees.
