Abstract: Objective　To investigate the growth and development of HIV-infected children initiating antiretroviral therapy (ART) and its influencing factors. Methods　This retrospective cohort study was conducted in Guangxi. HIV-infected children initiating free antiretroviral therapy (ART) from 2004 to 2019 were included. Z-score was calculated according to the Chinese Child Growth and Development Standard, the Cox-Stuart test was used for trend analysis, and the generalized estimating equation was used to analyze HAZ (Height-for-age Z-score)≥-2 and WAZ (Weight-for-age Z-score)≥-2 influencing factors. Results　A total of 943 children with HIV infection were enrolled in the cohort. The median HAZ at baseline and 1, 2, 5, and 10 years after treatment was -2.47, -2.14, -1.94, -1.55, -1.23, respectively, and the median WAZ was -1.85, -1.40, -1.30, -1.21, -1.09, respectively. By Cox-Stuart trend test, HAZ and WAZ showed an upward trend with the treatment time (P<0.05). The proportions of HAZ≥-2 at baseline and at 1, 2, 5, and 10 years after treatment were 38.1%, 46.5%, 51.6%, 66.8%, and 74.6%, respectively, and the proportions of WAZ≥-2 were 57.1%, 76.9%, 81.1%, 85.8% and 89.2%, respectively. According to Cox-Stuart trend test, the proportions of HAZ≥-2 and WAZ≥-2 increased with the treatment time (P<0.05). The results of multivariate generalized estimating equation analysis showed that the associated factors with HAZ≥-2 were that age at ART initiation was 3-7 years old (aOR=0.71, 95%CI: 0.53-0.94), age at ART initiation was >7 years old (aOR=0.66, 95%CI: 0.47-0.93), CD4 cell counts before ART was <200/μL (aOR=0.64, 95%CI: 0.47-0.87), WHO clinical stage before ART was Stage Ⅲ/Ⅳ (aOR=0.74, 95%CI: 0.56-0.97) and time on ART (aOR=1.01, 95%CI: 1.01-1.01); the associated factors with WAZ≥-2 were male (aOR=0.72, 95%CI: 0.53-0.97), WHO clinical stage before ART was Stage Ⅲ/Ⅳ (aOR=0.63, 95%CI: 0.45-0.86) and time on ART (aOR=1.01, 95%CI: 1.01-1.01). Conclusion　Antiretroviral therapy can effectively improve the growth and development status of children with HIV infection, but a large proportion of children still have stunted growth and development in the 10th year after treatment. It is necessary to strengthen the training of antiretroviral treatment staff and the publicity and education of parents of children infected with HIV. Improve the effect of antiviral treatment and guide children's nutrition reasonably.

OBJECTIVETo observe the clinical effects of two different circumcision procedures with the Shang Ring and compare their advantages and disadvantages.

METHODSA total of 527 adult males with phimosis or redundant prepuce underwent Shang Ring circumcision by conventional outward replacement (n = 254) and inward placement (n = 273), respectively. We observed the in-ring nocturnal pain, complications, ring-removal pain, degree of edema, recovery time, and patients' satisfaction after surgery, and compared them between the two groups.

RESULTSCompared with the conventional outward placement (5.9%) of the Shang Ring, the inward placement method showed the advantages of mild in-ring nocturnal pain, a low complication rate, significantly reduced ring-removal pain, and mild edema, but exhibited longer healing time.

CONCLUSIONIn Shang Ring circumcision for phimosis and redundant prepuce in adult males, each of the outward and inward placement methods has advantages and disadvantages of its own, but the latter is more advantageous and feasible.

OBJECTIVETo explore the feasibility of human leucocyte antigen (HLA) haploidentical related T-cell undepleted allogeneic bone marrow transplantation (Allo-BMT) combined with Chinese medicine for the treatment of leukaemia.

METHODSFour patients with chronic myeloblastic leukemia (CML) and 4 with acute myeloid leukemia (AML) received allo-BMT with graft from 1 - 3 HLA-mismatched related donors. All patients were pre-treated with standardized conditioning regimen consisting of high dose Ara-c, cyclophosphamide (CY) and total body irradiation (TBI) or busulfan. Donors were given G-CSF 250 microg/d for 7 days prior to marrow harvest. To prevent GVHD, besides application of CSA and MTX, ATG 2.5 mg/kg was given everyday for 4 days before transplantation, and MMF 1.0 g per day starting from the 7th day after transplantation. Chinese medicine for replenishing qi and yin and strengthening Pi and Wei was administrated orally after transplantation.

RESULTSSuccessful haematopoietic reconstruction was seen in all patients. The median days for reaching of granulocyte >0.5 X 10(9)/L and platelet > 20 x 10(9)/L were 12 (range 10-14) and 20 (range 18-25) days respectively. GVHD of skin in various grade was seen in 7 patients, among whom only one advanced to grade IV; besides, 2 accompanied with GVHD of gut, one with hemorrhagic cystitis, one died for concurrent infection on the 81st day, and one left hospital of his own accord on the 46th day. The median follow-up duration was 18 (range 2-32) months, during this period six patients were alive in a disease-free situation.

CONCLUSIONCombined therapy of HLA haploidentical related T-cell undepleted Allo-BMT and Chinese medicine plus immunosuppressants with pre-harvest G-CSF application in doner could effectively reduce the incidence of acute severe GVHD and raise the disease-free survival rate in treating leukaemia.
