Objective To investigate the clonal rearrangement of T cell receptor (TCR) ? gene which was of monoclonality,oligoclona-lity or clonal evolution /subclonality during the course of disease in patients with acute lymphoblastic leukemia (ALL) and its significance.Methods Between Sep. 2004 and Sep. 2007,70 patients with ALL were diagnosed in Department of Pediatrics of the First Affiliated Hospital of Guangxi Medical University,among which 51 cases were boys and 19 cases were girls.Their ages ranged from 2 years to 14 years (average age was 8.5 years).DNA samples were extracted from bone marrow cells or venous blood cells by phenol/phenol-isoamyl alcohol-chloroform/isoamyl alcohol law.DNA was amplified by polymerase chain reaction (PCR).Single strand conformation polymorphism analysis (SSCP) of silver stained technique was employed to detect PCR products.Results The amplification products of 23 cases of the 70 ALL patients were positive,in which 10 cases still had positive results in period of complete remission and had poor sensitivity to chemotherapeutic drugs,4 cases were of oligoclonality/ subclonality,and 2 cases were of clonal evolution with poor prognosis.Conclusions Detecting TCR ? gene rearrangement reflects clonal evolution of leukemia cells.The oligoclonality clonal evolution continues to exist,whose multiplication is the main reason of recurrent ALL.Detecting TCR? gene rearrangement,evaluating ALL of the patient's prognosis,the judgment of recurrence and the development of individualized treatment programs have great guiding significance,which can maximize the possibility of the sick children to make long-term disease-free survival and reduce the side effects of chemotherapy on the long-term basis.

AIM: To analyze and summarize the effect of glaucoma trabeculectomy in the department of ophthalmology in basic hospital.
METHODS: Postoperative intraocular pressure ( IOP ) , filtering bleb and complications of 316 cases (405 eyes) of patients with glaucoma after trabeculectomy were analyzed.
RESULTS: After follow- up 12mo, 76. 5% IOP was controlled in normal level. 42. 5% was filtration bleb typeⅠ, 33. 1% typeII, 14. 6% in typeⅢand 9. 9% in typeⅣ. Intraoperative complication rate was 2. 5%, that was 31.4% at postoperative early stage ( before discharge ) , and 6. 7% at postoperative long - term ( 6mo after discharge) .
CONCLUSION:Trabeculectomy for glaucoma can better solve the problem of high IOP. It is more mature in primary hospitals, but there are still a variety of intraoperative and postoperative complications.

Objective: To investigate the level of maternal and infant health literacy and its influencing factors among rural pregnant and lying-in women in Guian New Area, Guiyang City, so as to provide insights into maternal and infant health education. Methods: All pregnant and lying-in women included in health management in township hospitals of Guian New Area from October to December 2021 were selected using a stratified cluster random sampling method. Participants' basic features, maternal and infant health literacy and health education needs were collected using electronic questionnaires, and factors affecting maternal and infant health literacy were identified among pregnant and lying-in women using unconditioned multivariable logistic regression model. Results: A total of 918 valid questionnaires were recovered, and the participants included 325 pregnant women (35.40%), 823 married women (89.65%), 466 women with an educational level of junior high school and below (50.76%), 847 rural household registration (92.27%), 695 women with monthly family income of 3 200 Yuan and less (75.71%), and 267 women with maternal and infant health literacy (29.08%). Multivariable logistic regression analysis identified pluripara (OR=3.418, 95%CI: 1.689-6.919), educational level (diploma, OR=2.901, 95%CI: 1.230-6.842; bachelor and above, OR=6.282, 95%CI: 2.548-15.489), household monthly income per capita (3 201-5 000 Yuan, OR=2.373, 95%CI: 1.499-3.757; 5 001 Yuan and more, OR=7.752, 95%CI: 3.072-19.558), a disease history (OR=3.045, 95%CI: 1.175-5.406), use of maternal and child health manuals (OR=1.881, 95%CI: 1.345-2.632) and emphasizing health education (OR=1.735, 95%CI: 1.122-2.463) as factors promoting for the level of maternal and infant health literacy. In addition, pregnant and lying-in women's major maternal and infant health education needs included infant growth and development knowledge (745 women, 81.15%), management of common infant diseases (719 women, 78.32%), daily infant nursing (651 women, 70.92%) and infant nutrition and feeding (646 women, 70.37%). Conclusions The level of maternal and infant health literacy is low among rural pregnant and lying-in women in Guian New Area, and there is a high demand for health education. High attention should be paid to rural pregnant and lying-in women with a low educational level, low incomes, and primipara.

Objective To explore the clinical value of transvaginal four-dimensional hysterosalpingo-contrast sonography (TVS 4D-HyCoSy)in evaluation of the patency of fallopian tubes. Methods Totally 53 patients underwent SonoVue TVS4D-HyCoSy to observe the tubal patency. Results Among the 106 tubes in 53 patients, TVS 4D-HyCoSy showed 47 unobstructed tubes, 23 obstructed tubes, and 36 partially passable tubes. In unobstructed cases, the fallopian tubes were smooth and regular in morphology, and contrast agents flowed into and dispersed over pelvic cavity rapidly and evenly. In the cases of partially passable tube, fallopian tubes were discontinuous and irregular in morphology, and contrast agents lfowed into and dispersed over pelvic cavity slowly and unevenly. In obstructed cases, there were no or little contrast agents into the fallopian tubes. Compared with the results of laparoscopy, the diagnostic accuracy of TVS 4D-HyCoSy was 94.4%(17/18). Conclusions TVS 4D-HyCoSy is a useful tool in demonstrating the morphological features of fallopian tube, diagnosing intrauterinc adhesion and lesion and assessing the tubal patency.

The effective quality control in clinical practices is an effective guarantee for the authenticity and scientificity of the findings. The post-marketing reevaluation for traditional Chinese medicines (TCM) focuses on the efficacy, adverse reaction, combined medication and effective dose of drugs in the market by expanded clinical trials, and requires a larger sample size and a wider range of patients. Therefore, this increases the difficulty of quality control in clinical practices. With the experience in quality control in clinical practices for the post-marketing reevaluation for Kangbingdu oral for cold, researchers in this study reviewed the study purpose, project, scheme design and clinical practice process from an overall point of view, analyzed the study characteristics of the post-marketing reevaluation for TCMs and the quality control risks, designed the quality control contents with quality impacting factors, defined key review contents and summarized the precautions in clinical practices, with the aim to improve the efficiency of quality control of clinical practices. This study can provide reference to clinical units and quality control-related personnel in the post-marketing reevaluation for TCMs.

To propose a formula method of medicated diet based on medicinal property combination patterns in this paper under the context of lack of innovation in medicated diets. By analyzing the property combination patterns of traditional Chinese medicine and commonly used foods recorded in the pharmacopoeia, medicated diet formulae were optimized by using the greedy algorithm, with the property combination patterns of classical formulae based on the syndrome differentiation and treatment. In this paper, the Baihu Rensheng decoction, which is a classical formula for treating lung and stomach heat-derived diabetes, was taken for example in the formula design. As a result, totally 18 medicated diet formulae were developed and proved to be rational in the analysis on traditional Chinese medicines and nutriology. This method expands the way of thinking for personalized diet therapies and provides theoretical basis the industrial development and clinical application of medicated diets.

Objective To assess the proficiency of water monitoring laboratory at rural, county, and provincial levels in Guangdong province, to ensure the province's drinking water monitoring results accurate and reliable. Methods State quality of certified reference materials as water arsenic, fluoride and chloride of 90 copies each were numbered and distributed to 90 monitoring laboratories in the province for testing, The measurement results of the participatory labs were evaluated through normative values and expanded uncertainty, and were compared with those of robust statistics method. Results All participatory labs had timely feedback of their measurement results. The qualified rate was higher when arsenic was tested by hydride generation atomic fluorescence spectrometry and zinc-new silver salt of sulfuric acid spectrophotometric system, while fluoride and chloride by ion chromatography. The average qualified rates of water arsenic, fluoride and chloride of the province's rural drinking water quality monitoring laboratory were 66% (59/90), 72% (65/90) and 72% (65/90), respectively.Seven participatory labs failed the proficiency testing of all three analytes and unqualified rate was 7.8% (7/90)among the ninety participated monitoring labs. The qualified rates of robust statistics method for arsenic fluoride and chloride were greater than those evaluated by the expanded uncertainty, and large deviations with small sample sizes. Conclusions The testing ability of drink-water monitoring labs in Guangdong province has improved.However, by comparison with the requirements of national quality control and testing skills, there is still a gap. It is suggested that internal quality control be included in routine inspeetion to improve laboratory testing technology.
