Objective:To observe the clinical efficacy of treating infantile diarrhea due to spleen deficiency with five-step pediatric tuina of Huxiang school. Methods:Using a randomized controlled trial design, sixty eligible kids with diarrhea due to spleen deficiency were randomized into an observation group and a control group, with 30 cases in each group. The observation group was intervened by the five-step pediatric tuina method of Huxiang school, and the control group received conventional tuina treatment. The intervention was conducted once a day, consecutive 5-day treatment as 1 course, at a 2-day interval between courses, successively for a total of 4 courses. Changes in the primary and secondary symptoms of diarrhea due to spleen deficiency were observed, and the clinical efficacy was evaluated. Results: After treatment, the scores of primary and secondary symptoms and the general score of diarrhea due to spleen deficiency were improved; the improvements in fecal form and frequency, decreased appetite, bloating after meals and fatigue and sluggishness were more significant in the observation group than in the control group. Conclusion: The five-step pediatric tuina method of Huxiang school and conventional tuina both can improve the primary and secondary symptoms in infantile diarrhea due to spleen deficiency, while the former one can produce more significant efficacy.

Objective: To observe the difference in clinical efficacy between acupuncture with point selection based on syndrome differentiation along the meridians and acupuncture at non-meridian and non-acupoint points for functional dyspepsia (FD). Methods: A total of 74 FD patients were randomized into an observation group and a control group, with 37 cases in each group. Both groups received acupuncture treatment. Zusanli (ST 36) and Neiguan (PC 6) were selected in the observation group, with Taichong (LR 3) and Neiting (ST 44) added for excess syndrome, and Gongsun (SP 4) and Yinlingquan (SP 9) added for deficiency syndrome. Four non-meridian and non-acupoint points were selected in the control group. The treatments in both groups were performed once a day with a 2-day break after 5 consecutive treatments, which constituted one treatment course. A total of 4 courses were performed. The scores of Nepean dyspepsia index (NDI) and Leeds dyspepsia questionnaire (LDQ) were recorded before and after treatment, and during follow-up (8, 12, 16, 20 and 24 weeks after recruitment) to assess the clinical efficacy. Results: The NDI scores in the two groups after treatment and at each time point during follow-up were higher than those before treatment (all P<0.05), and the LDQ scores were lower than those before treatment (all P<0.05). The NDI scores after treatment and at each time point during follow-up in the observation group were higher than those in the control group (all P<0.01); the total LDQ score and scores of upper abdominal pain, postprandial satiety and upper abdominal burning sensation after treatment and at each time point during follow-up in the observation group were significantly lower than those in the control group (P<0.01 or P<0.05).. Conclusion: Acupuncture with point selection based on syndrome differentiation along the meridians has a better curative effect than acupuncture at non meridian and non-acupoint points in the treatment of FD.

OBJECTIVETo analyze the causes of injury and poisoning during construction of urbanization and industrialization and to explore proper measures.

METHODSThe data of the patients with injury and poisoning during construction of urbanization and industrialization treated in out hospital from 1998 to 2002 were retrospectively analyzed.

RESULTSThe number of discharged patients of injury and poisoning accounted for 29.2% of the total number (49800) of discharged patients in the corresponding period in our hospital, which was greater than that of other city and county hospitals, and accounted for 94.3% of the total number (15,411) of discharged patients of the Surgery Department in the corresponding period in our hospital. Injuries caused by motor vehicle traffic accidents, cutting and piercing instruments or objects, homicide and injury purposely inflicted by other persons and accidental falls held 78.9%. The number of the inpatients in 2002 increased by 83.3% compared with that of 1998, the number of injured and poisoned inpatients increased by 76.1% and these patients aged mainly at age of 15-39 years, holding 80.1%. In a year, the peak period of trauma patients was in summer because of hot weather; the fewest in February for the floating people went home for Spring Festival holidays.

CONCLUSIONSDuring construction of rural urbanization and industrialization, injuries and poisoning increase evidently and are the main tasks of surgical management. So to raise its treatment level and therapeutic effect is a key point.

OBJECTIVETo study the status of iron deposition in patients with β-thalassemia intermedia and major in mainland China.

METHODSThe status of transfusion and chelation was examined in 39 patients with β-thalassemia intermedia or major. Serum ferritin levels were measured. MRI T2* technique was used to detect cardiac and hepatic iron deposition.

RESULTSSerum ferritin levels ranged from the minimum of 1500 ng/mL up to a maximum of 11491 ng/mL. From liver MRI T2* measurement, 15 cases had severe hepatic iron deposition (38%) and moderate deposition was found in 15 cases (38%), mild in 7 cases (18%), and normal in 2 cases (5%). Heart MRI T2* showed severe heart iron deposition in 7 cases (18%), mild in 5 cases (13%), and normal in 27 cases (69%). One case had cardiac arrhythmia. Four cases were over 20 years of age, and presented with gonadal function hypoplasia. The majority of patients did not receive regular transfusion and they had delayed, suboptimal chelation due to financial problems. Serum ferritin level was closely related with timing and dosage of chelation.

CONCLUSIONSIn patients with β-thalassemia who do not receive early regular transfusion and iron chelation therapy, iron deposition may occur at an early age. Important organs and tissue functional lesions and related complications also result. Relevant agencies and family members should be aware of this trend and develop appropriate strategies to improve the medical condition and quality of life of patients with this disorder.

OBJECTIVETo design a clinically applicable transoralpharyngeal atlantoaxial reduction plate (TARP), introduce the operation procedure, and evaluate its preliminary clinical effects.

METHODSA novel TARP system, including butterfly titanium alloy plate, self-locking screws, atlantoaxial reductor and other operational instruments was developed. This system was applied clinically on five patients with irreducible atlantoaxial dislocation of congenital or traumatic origin. During operation, the reduction was completed by the combined action of the plate and the atlantoaxial reductor after transoral joint release and cord decompression. Bone graft granules were implanted between the bilateral atlantoaxial joints and TARP was used to immobilize subsequently the atlas and axis.

RESULTSClinical application demonstrated that TARP could induce instant reduction and that the method was operationally feasible and its postoperational effect was satisfactory.

CONCLUSIONSThe design of TARP is novel. The operational procedure is simple and easy to use. Furthermore, instant reduction can be completed during the operation and the fixation is relatively stable. TARP is an ideal alternative for irreducible atlantoaxial dislocation and may have excellent prospects for further clinical applications.

OBJECTIVETo evaluate the efficiency of one-step multiplex RT-PCR for identifying four common fusion transcripts (TEL/AML1, E2A/PBX1, MLL/AF4 and BCR/ABL) in children with acute lymphoblastic leukemia (ALL).

METHODSTotal RNA was extracted from bone marrow samples of 76 children who were newly diagnosed with ALL between January 2003 and December 2010. These RNAs were analyzed for TEL/AML1, E2A/PBX1, MLL/AF4 and BCR/ABL by one-step multiplex RT-PCR or common nested-multiplex PCR. The PCR products were confirmed by DNA sequencing.

RESULTSTEL/AML1 was found in 12 cases (the length of products was 298 bp in 9 cases and 259 bp in 3 cases), E2A/PBX1 was found in 3 cases (the length of products was 373 bp), BCR/ABL was found in 1 case (the length of products was 2 124 bp), and MLL/AF4 was found in 7 cases (the length of products was 427 bp in 1 case and 673 bp in 6 cases) using one-step multiplex RT-PCR combined with DNA sequencing. The results were consistent with those using common nested-multiplex PCR.

CONCLUSIONSOne-step multiplex RT-PCR may be another alternative for detection of common fusion transcripts in children with ALL.

OBJECTIVETo study the status of iron metabolism and erythropoietic proliferation in children with various genotypes of thalassemia.

METHODSSerum concentrations of ferritin (SF), transferrin receptor (sTfR) and erythropoietin (EPO) were measured in 158 children with thalassemia. The differences in the concentrations of the three indices among children with different genotypes of thalassemia were compared. The correlations of the hemoglobin level with sereum SF, sTfR and EPO levels were assessed.

RESULTSAmong the 158 children with thalassemia, 52(32.9%) were diagnosed with alpha-thalassemia minor, 27(17.1%) with HbH disease, 59(37.4%) with beta-thalassemia minor, 13(8.2%) with beta-thalassemia major, and 7(4.4%) with combining alpha beta thalassemia. The SF levels in children with HbH disease or beta-thalassemia major were significantly higher than those in the other thalassemia groups (P<0.01). The sTfR levels in children with beta-thalassemia major were the highest when compared with those in the other thalassemia groups (P<0.05). The EPO levels in children with beta-thalassemia major were also the highest when compared with those in the other thalassemia groups (P<0.01). There was a negative correlation between hemoglobin and EPO levels in children with HbH disease (r=-0.656, P<0.01) and beta-thalassemia major (r=-0.641; P<0.05).

CONCLUSIONSThe status of iron metabolism and erythropoietic proliferation is different in children with different genotypes of thalassemia. A combined measurement of SF, sTfR and EPO may reflect the status of erythropoietic proliferation.

OBJECTIVETo identify the relationship between the expression of alpha and beta-isoforms of glucocorticoid receptors (GR) in peripheral blood mononuclear cells (PBMC) and glucocorticoid resistance in children with idiopathic thrombocytopenia purpura (ITP).

METHODSReal-time PCR was used to detect the expression of GR alpha and GR beta mRNA in PBMC from 30 children with ITP (glucocorticoid-sensitive, n=18; glucocorticoid-resistant, n=12) and 10 healthy children (control group). Enzyme immunoassay was used to measure plasma levels of total glucocorticoids.

RESULTSThere were no significant differences in PBMC GR alpha mRNA levels among the glucocorticoid sensitive, the glucocorticoid-resistant and the control groups. Compared with the glucocorticoid-sensitive and the control groups, the expression of GR beta mRNA in the glucocorticoid-resistant group was significantly up-regulated (p<0.01). Plasma total glucocorticoids level in the glucocorticoid-resistant group was found to be much higher than that in the glucocorticoid-sensitive and the control groups (p<0.01).

CONCLUSIONSThe up-regulated expression of GR beta mRNA may associated with glucocorticoid resistance in children with ITP.

OBJECTIVETo study the feasibility of genetic diagnosis for female carriers of human glucose-6-phosphate dehydrogenase (G6PD) deficiency by reverse transcriptase-PCR-denaturing gradient gel electrophoresis (RT-PCR-DGGE).

METHODSBlood samples were collected from suspected 54 female carriers of G6PD deficiency. Total RNAs of peripheral blood were prepared and reverse-transcripted into cDNA. Design of 6 primer pairs for DGGE was based on 17 mutation sites of G6PD cDNA described in the Chinese population. Mutations in the coding region of G6PD gene were screened and genotyped by combination of PCR-DGGE and DNA sequencing.

RESULTSOne case of 1024C/T, 20 cases of 1376G/T and 12 cases of 1388G/A were detected in the 54 samples. The total detection rate was 66.1% (33/54).

CONCLUSIONSHeterozygous mutation rate in female carriers of G6PD deficiency detected by RT-PCR-DGGE is high. RT-PCR-DGGE is value of clinical diagnosis for G6PD-deficiency female carriers.

OBJECTIVETo design transoralpharyngeal atlantoaxial reduction plate (TARP), evaluate its biomechanical performance and observe its preliminary clinical effect.

METHODSA brand-new TARP system was designed, including butterfly titanium alloy plate, self-locking screws, atlantoaxial reductor and other operation instruments. Twelve fresh occipital bone-C(3) specimen were designed for biomechanical test including range of motion (ROM) (n = 6) and screw pull-out strength (n = 12). Preliminary clinical application of TARP was reported.

RESULTSThe reduction mechanism of the TARP system was designed cleverly. TARP had equal effect with Magerl + Brooks and it was more stable than the other three clinically widely used atlantoaxial fixators: Magerl, Brooks and anterior transarticular screw fixation through C(2) vertebral body. TARP's C(1) and C(2) screws were strong enough for atlantoaxial arthrodesis and their antipull-out performance was excellent. Clinical application on irreducible atlantoaxial dislocation proved that TARP had the function of instant reduction, the operation was feasible and the operation effect was significant.

CONCLUSIONTARP's design is novel and it has excellent biomechanical performance. The operation procedure is simple and reasonable. Furthermore, instant reduction could be completed during the operation and the fixation is strong. Above all, TARP is creative and will have excellent prospect.
