AIM To observe the curative effects of Modified Buzhong Yiqi Decoction (Codonopsis Radix,Astragali Radix,Atractylodis macrocephalae Rhizoma,ect.) on perioperative period of intertrochanteric fractures in elderly patients with Qi deficiency and blood stasis type.METHODS One hundred and twenty cases of elderly intertrochanteric fractures were randomly divided into treatment group and control group,60 cases in each group.All patients underwent closed fracture reduction and proximal femoral nail anti-rotation (PFNA) fixation.During the perioperative period,the control group only received conventional treatment,while the treatment group received conventional treatment and Modified Buzhong Yiqi Decoction once a day.The levels of interleukin-6 (IL-6),interleukin-10 (IL-10) and tumor necrosis factor (TNF-α) of both groups in preoperative and in the 1st day,the 7th day,the 14th day of postoperative were observed and compared.The complications and the curative effects according to the Harris score also were observed and compared between the two groups.RESULTS In preoperative,there was no significant difference in levels of IL-6,IL-10 and TNF-α between the two groups (P ＞ 0.05).The levels of IL-6 and TNF-α in the 1 st day of postoperative in the control group were significantly higher than those in the treatment group (P ＜0.05,P ＜0.01).And the levels of IL-10 were similar between the two groups (P ＞0.05).In addition,in the 7th day and the 14th day of postoperative,the levels of IL-6,IL-10 and TNF-α in both groups were all decreased,moreover,the descent degree in treatment group was more significant than those in the control group (P ＜ 0.05,P ＜ 0.01).The treatment group had the lower incidence of complications and the higher curative effects than those in the control group,both differences were statistically significant (P ＜0.05).CONCLUSION Modified Buzhong Yiqi Decoction applying to the perioperative period of femoral intertrochanteric fractures in elderly patients with Qi deficiency and blood stasis,can effectively reduce the perioperative inflammatory response,reduce the incidence of postoperative complications,and improve the curative effects.So it has a positive effect on the rehabilitation for the traumatic patients and is worthy of clinical promotion.

OBJECTIVETo study the expression of Bcl-2 and Bax in rat liver fibrosis model induced by CCl4 and the role of IFN-gamma.

METHODSLiver fibrosis was induced in rats by subcutaneous injection of CCl4. The rats were divided into fibrosis model group, Bie-Jia-Ruan-Gan-Tablet treatment group and IFN-gamma treatment group (0.2 MU.kg.d, i. m. for 12 weeks), and another 10 rats without any treatment were used as normal control. Bcl-2 and Bax proteins expression were detected by immunohistochemistry.

RESULTSBcl-2 was expressed weakly in the homogenate of hepatocytes and hepatic sinusoid in normal control rats, and it was expressed stronger in fibrous septae, portal area, hepatic sinusoid, the homogenate and membrane of hepatocytes and central vein in fibrosis model rats (3.87%+/-2.37% vs 9.46%+/-4.29%, t=2.83, P<0.05). Bax was expressed slightly in central vein and the hepatic sinusoid around, and it was expressed stronger in the homogenate of hepatocytes, hepatic sinusoid, fibrous septae, membrane of hepatocytes and epithelial cells of bile duct (3.50%+/-1.88% vs 9.80%+/-3.75%, t=3.72, P<0.01). Compared with that in fibrosis model rats, the expression of Bax was significantly lower in rats treated with IFN-gamma (9.80%+/-3.75% vs 5.85%+/-2.35%, t=2.98, P<0.01), but the expression of Bcl-2 was not significantly different (t=1.49, P>0.05), however it was significantly lower in fibrous septae in IFN-gamma-treated group than in model group (6.58%+/-4.13% vs 9.46%+/-4.29%, t=2.80, P<0.05).

CONCLUSIONThe expression of Bcl-2 and Bax increases in liver fibrosis model rats, and IFN-gamma can promote myofibroblasts apoptosis

OBJECTIVE: To investigate the risk factors for cow's milk protein allergy (CMPA) among infants through a multicenter clinical study. METHODS: A total of 1 829 infants, aged 1-12 months, who attended the outpatient service of the pediatric department in six hospitals in Shenzhen, China from June 2016 to May 2017 were enrolled as subjects. A questionnaire survey was performed to screen out suspected cases of CMPA. Food avoidance and oral food challenge tests were used to make a confirmed diagnosis of CMPA CMPA. A multivariate logistic regression analysis was used to investigate the risk factors for CMPA. RESULTS: Among the 1 829 infants, 82 (4.48%) were diagnosed with CMPA. The multivariate logistic regression analysis showed that maternal food allergy (OR=4.91, 95%CI: 2.24-10.76, P<0.05), antibiotic exposure during pregnancy (OR=3.18, 95%CI: 1.32-7.65, P<0.05), and the introduction of complementary food at an age of <4 months (OR=3.55, 95%CI: 1.52-8.27, P<0.05) were risk factors for CMPA, while exclusive breastfeeding (OR=0.21, 95%CI: 0.08-0.58, P<0.05) and the introduction of complementary food at an age of >6 months (OR=0.38, 95%CI: 0.17-0.86, P<0.05) were protective factors. CONCLUSIONS The introduction of complementary food at an age of <4 months, maternal food allergy, and antibiotic exposure during pregnancy are risk factors for CMPA in infants.

In vitro amplified human leukocyte antigen (HLA)-haploidentical donor immune cell infusion (HDICI) is not commonly used in children. Therefore, our study sought to evaluate its safety for treating childhood malignancies. Between September 2011 and September 2012, 12 patients with childhood malignancies underwent HDICI in Sun Yat-sen University Cancer Center. The median patient age was 5.1 years (range, 1.7-8.4 years). Of the 12 patients, 9 had high-risk neuroblastoma (NB) [7 showed complete response (CR), 1 showed partial response (PR), and 1 had progressive disease (PD) after multi-modal therapies], and 3 had Epstein-Barr virus (EBV)-positive lymphoproliferative disease (EBV-LPD). The 12 patients underwent a total of 92 HDICIs at a mean dose of 1.6×10(8) immune cells/kg body weight: 71 infusions with natural killer (NK) cells, 8 with cytokine-induced killer (CIK) cells, and 13 with cascade primed immune cells (CAPRIs); 83 infusions with immune cells from the mothers, whereas 9 with cells from the fathers. Twenty cases (21.7%) of fever, including 6 cases (6.5%) accompanied with chills and 1 (1.1%) with febrile convulsion, occurred during infusions and were alleviated after symptomatic treatments. Five cases (5.4%) of mild emotion changes were reported. No other adverse events occurred during and after the completion of HDIDIs. Neither acute nor chronic graft versus host disease (GVHD) was observed following HDICIs. After a median of 5.0 months (range, 1.0-11.5 months) of follow-up, the 2 NB patients with PR and PD developed PD during HDICIs. Of the other 7 NB patients in CR, 2 relapsed in the sixth month of HDICIs, and 5 maintained CR with disease-free survival (DFS) ranging from 4.5 to 11.5 months (median, 7.2 months). One EBV-LPD patient achieved PR, whereas 2 had stable disease (SD). Our results show that HDICI is a safe immunotherapy for childhood malignancies, thus warranting further studies.

Objective:To investigate the effectiveness and compliance of the 2 year specific immunotherapy in patients with allergic rhinitis. Method:Two hundred and sixty-two patients of allergic rhinitis were treated with SLIT for 2 years. The symptom questionnaire about effectiveness and compliance were obtained 2 years after SLIT. The patient satisfaction was also investigated. Result:Sixty patients had complete compliance and 202 patients had poor compliance. Of the 142 children, 40 (28%) cases had complete compliance, and of the 118 adult patients, 20 cases (17%) had complete compliance. There was obvious difference between the two (P<0.05). Comparing of before and after treatment, total medication score, total nasal symptom score and every symptom score decreased obviously (P<0.05). Two years after treatment, the total effective rate was 63%,there was significant difference between the children group and the adult group (P<0.05). Conclusion:There are a lot of factors affecting the treatment compliance of sublingual immunotherapy, such as patients, family, health care workers and social support, etc. In the course of treatment, a series of strategies can be adopted to improve the treatment compliance. SLIT is an effective method for the treatment of allergic rhinitis, and the treatment effect of children is better.

OBJECTIVES: To study the clinical features and prognosis of high hyperdiploid (HHD) childhood acute lymphoblastic leukemia (ALL). METHODS: A retrospective analysis was performed on the medical data of 1 414 children who were newly diagnosed with ALL and were admitted to five hospitals in Fujian Province of China from April 2011 to December 2020. According to karyotype, they were divided into two groups: HHD (n=172) and non-HHD (n=1 242). The clinical features and treatment outcome were compared between the two groups, and the factors influencing the prognosis were further explored. RESULTS: Among the 1 414 children with ALL, 172 (12.16%) had HHD. Compared with the non-HHD group, the HHD group had significantly lower proportions of children with risk factors for poor prognosis at diagnosis (age of onset ≥10 years or <1 year, white blood cell count ≥50×10⁹/L, and T-cell phenotype) or positive fusion genes (TEL-AML1, BCR-ABL1, E2A-PBX1, and MLL gene rearrangement) (P<0.05). The HHD group had a significantly higher proportion of children with minimal residual disease (MRD) <0.01% at the end of induction chemotherapy (P<0.05). The 10-year event-free survival (EFS) rate and overall survival (OS) rate in the HHD group were significantly higher than those in the non-HHD group (P<0.05). The univariate analysis showed that the number of chromosomes of 58-66, trisomy of chromosome 10, trisomy of chromosome 17, bone marrow MRD <1% on day 15 or 19 of induction chemotherapy, and bone marrow MRD <0.01% on day 33 or 46 of induction chemotherapy were associated with a higher EFS rate (P<0.05), and trisomy of chromosome 10 was associated with a higher OS rate (P<0.05). The multivariate Cox analysis showed that trisomy of chromosome 17 was closely associated with a high EFS rate (P<0.05). CONCLUSIONS The ALL children with HHD have few risk factors for poor prognosis at diagnosis and often have good prognosis. The number of chromosomes and trisomy of specific chromosomes are associated with prognosis in these children.

To preliminarily analyze the prevention and control of COVID-19, a general hospital outpatient service took six management measures, including setting up a leading group, building rules and regulations, infection control and supervision, special training, humanized service, public opinion propaganda. After nearly two months, the rates of both body temperature monitoring and epidemiological history screening are 100%, the medical staff infection rate is zero, and no cross infection between the patients due to adopting outpatient service comprehensive management measures which had strong organization and leadership, effective targeted training, effective control of all links in epidemic prevention and control work. During the fight against COVID-19, outpatient management played an important role in hospital management. The above approaches provide valuable experience for preventing the spread of infectious diseases effectively and winning the biological weapon wars in the future.
