Objective To analyze the relation between ~(99)Tc~m-DTPA renal dynamic imaging and pathological changes in patients with lupus nephritis (LN).Methods Ten normal control and 29 patients with LN underwent ~(99)Tc~m-DTPA renal dynamic imaging.The LN patients were divided into two groups:silent LN (SLN) group,18 patients;and obvious LN (OLN) group,11 patients.For each case,glomerular filtration rate (GFR),peak time (t_p),half excretion time (t_(1/2)) and the excretion rate at 20 min (R_(20)) were calculated.Assessment of renal function on the scintigraphic images was evaluated by nuclear medicine physicians.The t-test,Fisher'exact probability and R×C association were used for data analysis.Results There were significant differences between normal people and two goups of LN in tp(t=5.3,9.3,both P<0.05),t_(1/2)(t=6.9,12.0,both P<0.05)and R_(20)(t=10.1,12.1,both P<0.05).As to GFR,there was significant decrease in OLN patients(t=4.1,P<0.05),but not in SLN patients(t=1.7,P>0.05).Diagnoses of renal function by renal dynamic imaging were compared with the renal pathological changes (r=0.2273,P<0.05).Conclusions ~(99)Tc~m-DTPA renal dynamic imaging is useful for evaluation of the early stage renal function for LN patients and to diagnose LN patients with no symptom of renal impairment.It may help to assess the degree of renal parenchymal damage while obviating the need for renal biopsy in these patients.

OBJECTIVETo study the blood pressure (BP) changes in the liver transplant recipients.
METHODSA total of 206 patients without preoperation hypertension received liver transplantation in our hospital from February 2001 to July 2005. The BP level and serum immunosuppressant concentration at preoperation and various time points post operation were determined.
RESULTSCompared with the preoperation, the average systolic and diastolic pressure was significantly increased at the 2 week, 1, 2, 4 and 6 months post operation. The mobility of hypertension increased significantly after liver transplantation, with the highest mobility (46.49%) at the 1st month post operation. There was no linear correlation between the immunosuppressant (FK506) concentration and the BP level at any time point.
CONCLUSIONThere was a high hypertension incidence after liver transplantation. Although the use of immunosuppressive drugs accompanied with the BP increase, there was no linear correlation between the immunosuppressant concentration and the BP level post operation.

OBJECTIVEAfter performed symptom-limited maximum cardiopulmonary exercise testing (CPET) before and after acute alkalized blood, we repeated CPET with pure oxygen.
METHODSFive volunteers, 3hr after alkalizing blood room air CPET, re-performed CPET inhaling from Douglas bag connected with pure oxygen tank. We compared with those of room air CPETs before and after alkalized blood.
RESULTSAfter alkalized blood oxygen CPET had a similar response pattern as those of CPETs before and after blood alkalization. During the CPET, all breath frequency, minute ventilation and tidal volume at each stage were similar to those of CPETs before and after alkalized blood (P > 0.05),except there was a lower peak tidal volume than those of both CPETs and a slightly higher resting minute ventilation only than CPET after alkalized blood (P > 0.05). After alkalized blood, oxygen CPET, all PaO2 and SaO2 and most Hb were lower than those of both CPETs (P < 0.05). The pHa and [HCO3-]a were higher than those of CPET before alkalized blood (P < 0.05); but were not CPET after alkalized blood (P > 0.05). PaCO2 was similar to that of CPET before alkalized blood (P > 0.05), but was lower than that of CPET after alkalized blood at resting and warm-up (P < 0.05); then was similar to both CPETs at anaerobic threshold (P > 0.05); but was higher at peak exercise higher than those of both CPETs (P < 0.01). Oxygen increased 2,3 volunteers' workload and time at AT and peak exercises.
CONCLUSIONRespiratory response pattern to oxygen CPET after alkalized blood is similar to those of both CPETs before and after alkalized blood. The CPET response is dominantly depended upon metabolic rate, but not levels of pHa, PaCO2 and PaO2.

8.Research advances in candidate genes for autism spectrum disorder.
Chinese Journal of Contemporary Pediatrics 2016;18(3):282-287
Autism spectrum disorder (ASD) is a kind of neurodevelopmental multigenic disorder. More than one hundred of candidate genes for ASD have been reported. The candidate gene research for ASD involves in chromosome loci and screening of candidate genes and epigenetic abnormalities for candidate genes. The reported genes encode neural adhesion molecules, ion channels, scaffold proteins, protein kinases, receptor protein and carrier protein, signaling modulate molecules and circadian relevant proteins. The research of mutation screening and expression regulation of candidate genes can help to elucidate genetic mechanisms for ASD, and may provide new approaches for the diagnosis and treatment of this disorder. This article reviews the research advance in candidate genes for ASD.

OBJECTIVETo investigate the dynamic changes of the epididymal size 1 year after vasectomy.
METHODSFifty male volunteers received vasoligation. Before and at 1, 2, 3, 6, and 12 months after operation, we measured the size and detected the internal echoes of the epididymis using color Doppler ultrasonography.
RESULTSThe bilateral epididymides were both thickened post-operatively in all the 50 cases, with statistically significant differences between the baseline and the 1st month, the 1st and the 2nd month, the 2nd and the 3rd month, or the 3rd and the 6th month after surgery (all P < 0.01), but not between the 6th and the 12th month (P > 0.05).
CONCLUSIONWithin 6 months after vasectomy, the bilateral epididymides manifested a progressive thickening, but basically restored their balance of secretion-absorption after 6 months.
