Objective To investigate the value of detecting BK virus(BKV)in urine of renal al- lograft recipients for the diagnosis and treatment of BKV infection.Methods Using polymerase chain re- action(PCR)method combined with DNA sequencing,61 urine samples from renal allograft recipients,30 u- fine samples from dialytic patients and 30 urine samples from healthy volunteers(controls)were detected. The results were compared among the 3 groups.Results The BKV positive rate in renal allograft recipi- ents was 36.1%,compared with 13.3% in dialytic patients(P＜0.05)and 0.0% in controls(P＜0.05). One renal allograft recipient who was positive for BKV developed ureteral obstruction.The BKV positive rate was 40.9%(9/22)in renal allograft recipients with rejection episode,compared with 33.3%(13/39)in the recipients without rejection episode(P＞0.05);and the BKV positive rate was 36.0%(18/50)in the recip- ients with normal graft function,compared with 36.4%(4/11)in the recipients with abnormal graft function (P＞0.05).Conclusions Renal allograft recipients are the high risk population who may develop BKV viruria.There is no correlation between recipients with or without rejection episode and BKV viruria,and also no correlation between recipients with normal or abnormal graft function and BKV viruria.Detection of BKV in the urine of renal allograft recipients is helpful in differential diagnosis of BKV induced ureteral obstruc- tion,and PCR method for detecting BKV DNA can be used to screen for BK virus-associated nephropathy (BKVAN).

AIM:To evaluate the efficacy and safety of large sized continuous curvilinear capsulorhexis ( CCC ) involving zonular area in manual small incision cataract surgery ( MSICS) .
METHODS:Totally 1 443 cataract patients ( 1 965 eyes ) underwent MSICS, in which large CCC up to 7-8mm were performed . The related conditions such as success rate of performing CCC, capsule rupture, corneal edema and visual acuity after surgery were recorded and statistically analyzed.
RESULTS:In total of 1 965 eyes, 1 942 eyes ( 98. 83%) had successful CCC, 15 eyes (0. 76%) had a radial tear which could not be saved when performing CCC, 8 eyes (0. 41%) had anterior capsule opened with a cystotome or a scissor due to capsule membrane calcification. No posterior capsule rupture occurred, and intraocular lens was transplanted in all cases. Transient corneal edema was noted in 36 eyes (1. 83%). One day after surgery, 1650 eyes (83. 97%) had visual acuity ≥0. 5, 1867 eyes (95. 01%) ≥0. 3. No unstable intraocular lens was noted in all cases.
CONCLUSION:Large CCC technique for MSICS is safe and reliable, not decreasing stability capsular bag and intraocular lens. It is of high originality despite zonular area is involved so that it is worthy of application in basic medical institutions.

AIM To examine the effect of metabotropic glutamate receptor ligand (s) 4 carboxy 3 hydroxyphenyl glycine 〔(s) 4C3HPG〕 on kainic acid induced epileptic seizures and brain damage in rats. METHODS Rats were given (s) 4C3HPG (500 nmol/rat) by icv infusion prior to kainic acid (KA) injection ip(10 mg?kg -1 ). The behavoir changes, electrographic seizure duration and histological alterations between different group of rats were compared. RESULTS (s) 4C3HPG markedly reduced seizures severity in response to kainate. The seizure score in the rat with (s) 4C3HPG injection icv was significantly lower than that of control during the first three hours observation period after KA administration ( P

Objective To investigate the iodine nutritional status in the key populations before and after the adjustment of salt iodine content in Yantai of Shandong.Methods In 2010 (the pre-adjustment period) and 2014,2015 (the post-adjustment period),the changes in the residents' iodized salt,the goiter prevalence and urinary iodine of children aged 8-10,the urinary iodine of pregnant women,and the iodine content of drinking water before and after the adjustment were analyzed.Results The coverage rate of iodized salt and the edible rate of qualified iodized salt were 98.27％ and 97.28％,respectively before the adjustment of salt iodine content,and 97.44％ and 96.14％ after the adjustment.The mean of salt iodine after the adjustment (21.96 mg/kg) was significantly lower than that of 2010 (31.45 mg/kg,t =66.29,P ＜ 0.05).The goiter prevalence of children aged 8-10 by thyroid palpation was 0.92％ in 2010,while it was 1.89％ by ultrasonic in 2014,2015.There was significant difference in the iodine nutritional status of children in 2010 (191.0 μg/L) and in 2014,2015 (173.0 μg/L,Z =3.56,P ＜ 0.05).The difference of iodine nutritional status in pregnant women between pre-adjustment (154.0 μg/L) and post-adjustment (130.4 μg/L) was also significant (Z =5.54,P ＜ 0.05).The median of water iodine was 5.4 μg/L after the adjustment.There were 52 towns with medians of water iodine below 10 μg/L.Conclusions The coverage rate of iodized salt and the edible rate of qualified iodized salt have all met the national standard before and after the adjustment of salt iodine content.The mean of salt iodine during 2014,2015 is significantly lower than that of 2010.Before and after the adjustment,the goiter rates of children aged 8-10 are all below 5％.The adjustment of salt iodine content is more suitable to children aged 8-10 than to pregnant women currently.It is suggested that pregnant women eat more foods rich in iodine.

OBJECTIVETo analyze the relationship of anxiety state with CD4(+) level and CD4(+)/CD8(+) ratio and to observe the effect of Chinese medicine (CM) treatment on anxiety in chronic hepatitis B (CHB) patients.

METHODSThe anxiety state of 120 CHB patients was evaluated based on Hamilton Anxiety Scale (HAMA) scoring. According to the scores, 63 patients with scores ≥14 were classified to anxiety and 57 patients with scores <14 to non-anxiety. The differences in CD4(+) cells and CD4(+)/CD8(+) ratio between patients with anxiety and non-anxiety were analyzed. Moreover, 63 patients with anxiety were randomized into two groups: 31 in the control group were treated with lamivudine (100 mg per day) alone and 32 in the observation group were given equal dosage lamivudine combined with CM treatment depending on syndrome differentiation, all for 12 weeks. The effects of treatment on anxiety state and T-lymphocyte subsets as well as its impact on some CHB-related indices were observed and compared.

RESULTSThe anxiety state of CHB patients was negatively correlated with CD4(+) and CD4(+)/CD8(+); the level of CD4(+) in patients with anxiety was significantly lower than that in non-anxiety patients (P<0.01 or P<0.05). After treatment, anxiety state in the observation group was significantly improved, with their HAMA scores significantly lowered (P<0.01), and the levels of CD4(+) and CD4(+)/CD8(+) were significantly higher than those in the control group (P<0.05 or P<0.01). Moreover, the alanine transaminase recovery rate and the HBV-DNA-negative conversion rate in the observation group were significantly higher than those in the control group, respectively (P<0.05).

CONCLUSIONSThe anxiety state of CHB patients was related to CD4(+) and CD4(+)/CD8(+) levels. CM treatment could improve the anxiety state and showed certain regulatory effect on the patients' immune system.
