OBJECTIVE: To investigate the causes of graft loss in kidney transplant recipients. METHODS: We retrospectively analyzed the clinical data of 135 recipients with graft loss after renal transplantation in the Eighth Medical Center of Chinese PLA General Hospital from January 1, 2002 to January 1, 2022. RESULTS: A total of 135 kidney transplant recipients experienced graft failure. The causes of graft loss included graft rejection (70 cases, 51.8%), death of the recipients with functional graft (37 cases, 27.4%), surgical complications (12 cases, 8.9%), drug toxicity (4 cases, 3.0%), carbapenem-resistant Klebsiella pneumoniae infection (4 cases, 3.0%), polyoma BK virus-related nephropathy (3 cases, 2.2%), primary nonfunctioning kidney (2 cases, 1.5%), recurrence of primary disease (2 cases, 1.5%), and prerenal acute renal failure (1 case, 0.7%). CONCLUSION The main cause of graft loss after renal transplantation is graft rejection, and the secondary cause is death of the recipient with functional graft, and other reasons can be rare.

Since December 2019, the corona virus disease 2019 (COVID-19) caused by the 2019 novel coronavirus (2019-nCoV) has been reported in Wuhan, Hubei Province. Almost 70% of patients susceptible to 2019-nCoV are over age of 50 years, with extremely large proportion of critical illness and death of the elderly patients. Meanwhile, the elderly patients are at high risk of osteoporotic fractures especially osteoporotic vertebral compression fractures (OVCF). During the prevention and control of COVID-19 epidemic, orthopedists are confronted with the following difficulties including how to screen and protect OVCF patients, how to accurately diagnose and assess the condition of OVCF patients with suspected or confirmed COVID-19, and how to develop reasonable treatment plans and comprehensive protective measures in emergency and outpatient clinics. In order to standardize the diagnosis and treatment of patients with OVCF diagnosed with COVID-19, the authors jointly develop this expert consensus. The consensus systematically recommends the standardized emergency and outpatient screening and confirmation procedures for OVCF patients with suspected or confirmed COVID-19 and protective measures for emergency and outpatient clinics. Moreover, the consensus describes the grading and classification of OVCF patients diagnosed with COVID-19 according to the severity of illness and recommends different treatment plans and corresponding protective measures based on the different types and epidemic prevention and control requirements.

OBJECTIVETo investigate the risk factors for the development of congenital anal atresia in neonates.

METHODSA total of 70 neonates who were admitted to 17 hospitals in Foshan, China from January 2011 to December 2014 were enrolled as case group, and another 70 neonates who were hospitalized during the same period and had no anal atresia or other severe deformities were enrolled as control group. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for the development of congenital anal atresia.

RESULTSThe univariate analysis revealed that the age of mothers, presence of oral administration of folic acid, infection during early pregnancy, and polyhydramnios, and sex of neonates showed significant differences between the case and control groups (P<0.05). The multivariate logistic regression analysis revealed that infection during early pregnancy (OR=18.776) and male neonates (OR=9.304) were risk factors for congenital anal atresia, and oral administration of folic acid during early pregnancy was the protective factor (OR=0.086).

CONCLUSIONSInfection during early pregnancy is the risk factor for congenital anal atresia, and male neonates are more likely to develop congenital anal atresia than female neonates. Supplementation of folic acid during early pregnancy can reduce the risk of congenital anal atresia.

OBJECTIVETo compare efficacy differences between fire filiform needle combined with mild moxibustion and gabapentin combined with sham acupuncture for postherpetic neuralgia (PHN).

METHODSOne hundred cases of PHN were randomly divided into a needle group and a medicine group, 50 cases in each one. In the needle group, pricking method of fire filiform needle was given at the Ashi points, and then mild moxibustion was applied for 15 min. In the medicine group, the oral administration of gabapentin capsule and sham acupuncture at non-acupoints in the distal end of lesions were applied. The treatment was required for 21 days in both groups. The visual analogue score (VAS) was recorded before treatment and on the 1st day, 2nd day, 3rd day, 6th day, 9th day and 12th day of treatment. The most severity of pain within last 24 h, preset severity of pain, immediate analgesia effect and starting time of pain relief were observed, also the efficacy was assessed and improvement of symptoms was observed in the follow-up visit.

RESULTSThe total effective rate was 94.0% (47/50) in the fire filiform needle group, which was superior to 86.0% (43/50) in the medicine group (P < 0.05). Compared with medicine group, the VAS of the most severity of pain within last 24 h was obviously reduced after the 2nd treatment in the fire filiform needle group while that of present severity of pain was relieved after the 1st treatment (both P < 0.05). The immediate analgesia effect in the fire filiform needle group was obviously superior to that in the medicine group in the first three times of treatment (all P < 0.05). The average time of pain relief was (3.91 +/- 0.82) days in the fire filiform needle group, which was significantly earlier to (6.53 +/- 1.13) days in the medicine group (P < 0.05). 26 cases were cured in the fire filiform needle group in the follow-up visit, which was superior to 2 cases in the medicine group (P < 0.05). The improvement of VAS, pain range and sleep quality in the needle group were also superior to those in the medicine group (all P < 0.05). The direct medical cost in the fire filiform needle group was (232.32 +/- 48.108) yuan, which was significantly lower than (466.00 +/- 41.09) yuan in the medicine group (P < 0.05). There was only one case of adverse effect in the medicine group during the treatment.

CONCLUSIONThe fire filiform needle combined with mild moxibustion could obviously relieve the pain in PHN patients, which has superior immediate analgesia effect and pain relieving time compared with gabapentin, which also has less adverse effects and cheap cost.

OBJECTIVETo evaluate cyto- and molecular genetic characteristics of adult patients with acute lymphoblastic leukemia (ALL) and its prognostic significance.

METHODSTwo hundred and seventeen adult patients with ALL were analyzed for cyto- and molecular genetic characteristics with combined conventional cytogenetics, fluorescence in situ hybridization (FISH), real-time quantitative PCR (qPCR) and nested PCR. Significance of genetic findings for prognosis was evaluated.

RESULTSt(9;22)(q34;q11)/BCR-ABL has been the most frequent abnormality found in the cohort (56.3%). And 22.4% of cases with BCR-ABL detected by FISH was negative by cytogenetic analysis. Ratio of patients in high-risk group increased with age; Patients with B-ALL had a higher risk group than the average-risk group (98.40% vs. 65.70%, P=0.000). The overall survival (OS) rates at 3-month (67.30% vs. 85.10%, P=0.042), 6-month (55.1% vs. 80.4%, P=0.008), 12-month (34.0% vs. 59.1%, P=0.017) and 24-month (13.0% vs. 36.6%, P=0.010) were lower in high-risk group than in average-risk group, with medium OS time (11 months, 95% CI 8.0-13.9) being significantly shorter compared with the average-risk group (19 months, 95%CI 10.8-27.1).

CONCLUSIONAdult patients with ALL have unique cyto- and molecular genetic characteristics, which has important value for prognosis and guiding treatment. Moreover, combined cytogenetic and molecular genetic techniques can precisely define sub-groups of ALL patients.

This study was purposed to investigate the incidence of mixed lineage leukemia (MLL) gene rearrangement and partner gene types as well as the clinical features and prognosis of acute leukemia (AL) with this rearrangement through detection in adult AL using combination of 3 techniques, and to evaluate the clinical value of this combination detection. The MLL gene rearrangement in 183 cases of adult AL was detected by combination of conventional cytogenetics, split signal FISH and multiplex nested PCR. The results showed that the incidence of MLL rearrangements in adult patients with AL was low (8.2%), and MLL-AF4 fusion gene was most common and predominant in acute lymphoblastic leukemia (ALL), while the MLL-AF6 and MLL-AF9 were most frequent in acute myeloid leukemia (AML). Extramedullary involvements were found in 40% of MLL-rearranged AL patients, and 33.3% of patients with MLL-rearranged AL reached to complete remission within 30 days during induction chemotherapy. In addition, in this cohort of MLL-rearranged adult AL patients, the 3-month relapse rate and 6-month overall survival rate were 50.0% and 50.0% respectively. It is concluded that the rate of missed diagnosis of CC technique for patients with MLL-rearranged AL reached to 60% in this study, while the combination of CC, FISH and multiplex nested PCR has been confirmed to have important significance for evaluating prognosis and conducting clinical therapy of patients with MLL-rearranged AL.

OBJECTIVETo discuss the clinical safety about repairing the peripheral nerve defects with the acellular allogeneic nerve.

METHODSThe 41 patients (male 38, female 3, age 10 - 55 years old, average 28.9 years old) who were performed chemically extracted acellular nerve allograft transplanting to repair nerve defects from 2002 to 2011. The average interval from injury to nerve repairing was 4.1 months (range, 10 hours to 9 months). There were 41 cases nerve defects including 10 brachial plexus nerves, 3 radial nerves of upper arm, 4 ulnar nerves of forearm, 12 digital and toe nerves, 2 sciatic nerves, 2 femoral nerves, 3 tibial nerves and 5 common peroneal nerves. There were 12 cases combined fractures and 20 soft tissue injury or defects. The average length of the nerve allograft to bridge the nerve defects was 6.1 cm (range, 2 - 10 cm). No immunosuppressive drugs were used in all cases. The clinical safety was evaluated through physical examination, blood biochemistry and immunity detection.

RESULTSAll cases were followed up post-operation. They got primary wound healing except 2 superficial infection who got delay healing through dressings changing. No any adverse effects happened including immunological rejection, hypersensitivity reaction, deep infection, hepatotoxicity and nephrotoxicity.

CONCLUSIONSIt is safe and feasible to repairing human peripheral nerve defects with chemically extracted acellular nerve allograft.
