Background::Psoriasis is a chronic systemic inflammatory disease, and hyperuricemia is a common comorbidity in patients with psoriasis. However, there are limited reports on the relationship between serum uric acid levels and biological treatment efficacy. The purposes of this study were to compare the differences in serum uric acid levels between patients with psoriasis and healthy controls and analyze the risk of hyperuricemia.Methods::A total of 196 patients with psoriasis and 191 age- and sex-matched healthy controls were enrolled in this retrospective cohort study. One hundred and twenty-seven patients with severe psoriasis were treated with biologics. Sixty-eight patients received adalimumab, and 59 patients received secukinumab. Serum uric acid levels were measured at baseline, week 24, and week 48 of treatment.Results::Patients with psoriasis had higher serum uric acid levels than healthy controls (6.4 ± 1.7 mg/dL vs. 5.7 ± 1.5 mg/dL, P < 0.001). Hyperuricemia was found in 33.7% (66/196) of patients with psoriasis, which was significantly higher than that in healthy controls (13.1% [25/191], P < 0.001). Serum uric acid levels and hyperuricemia were not related to the severity of psoriasis ( P > 0.05). No significant changes in serum uric acid levels and hyperuricemia were observed following adalimumab treatment ( P > 0.05). The serum uric acid level in patients treated with secukinumab was 6.7 ± 1.6 mg/dL at week 24, which was not statistically different from that at baseline (6.6 ± 1.4 mg/dL, P = 0.885). Serum uric acid levels were significantly decreased at week 48 (6.3 ± 1.5 mg/dL vs. 6.6 ± 1.4 mg/dL, P = 0.007) in patients treated with secukinumab. Secukinumab had no significant effect on hyperuricemia either ( P > 0.05). Conclusions::The serum uric acid levels and prevalence of hyperuricemia in patients with psoriasis were significantly higher than those in healthy controls. Secukinumab treatment for 48 weeks successfully decreased serum uric acid levels in patients with psoriasis, whereas adalimumab had no significant effect on serum uric acid levels.

The clinical data of 2 infants with infantile glycogen storage disease type II (GSD II) from one pedigree were collected. The method of dried blood spots (DBS) was applied to collect peripheral blood samples, and the activity of acid alpha-D-glucosidase (GAA) in leukocytes was measured. The coding region of GAA gene in this pedigree was amplified by polymerase chain reaction and then direct sequencing was used to analyze mutations in GAA gene. The two infants were twins, who were admitted to the hospital due to feeding difficulties, generalized muscle weakness and hypotonia, cardiomegaly, and cardiac insufficiency when they were 10 months old. The GAA activity in leukocytes in the two infants was significantly lower than in normal controls. Gene sequencing revealed 2 compound heterozygous mutations in the two infants, i.e., G1942A and G2214A, respectively. G1942A had been proved pathogenic, and the latter one, G2214A, was a nonsense mutation, resulting in the change of tryptophan, the 738th amino acid of GAA, into a stop codon. The two infants were diagnosed with GSD II by gene detection and no enzyme replacement therapy could be provided to them. Follow-up visits showed that the two infants died at home at the age of 15 months and 17 months, respectively. GSD II is caused by deficiency of GAA activity resulting from mutation of GAA gene. The detection of GAA activity in peripheral blood by DBS and GAA gene detection are effective and feasible methods for diagnosis of GSD II.

Objective To investigate the long-term follow-up results of patients treated with radical nephrectomy for small renal carcinoma.Methods Between January 1992 and June 2004,a total of 56 pa- tients(41 men and 15 women;mean age,54 years;age range,19-71 years)underwent radical nephrectomy for small renal carcinoma.The clinical data and long-term follow-up results of the 56 cases were analyzed ret- rospectively.All the patients were followed by questionnaire;and the 5-and 10-year survival rates were calcu- lated by Kaplan-Meier method.Results None of the patients was found to have metastasis preoperatively. Postoperative pathology showed renal clear cell carcinoma in 44 cases,granular cell carcinoma in 7,and mixed cell carcinoma in 5.Among these cases,ipsilateral adrenal metastasis was found in 1 case,local lymph- aden metastasis in 2,and perirenal fat metastasis in 4.Postoperatively,49 of the 56 patients(87.5%)were followed for 11-155 months with a mean of 71 months.The 5-and 10-year survival rates were 81.7% and 66.9%,respectively.Five patients died of metastasis from renal carcinoma.Conclusions Radical ne- phrectomy for small renal carcinoma has favorable long-term effects,therefore it is an optimal surgical proce- dure for small renal carcinoma.

Background: We estimated the incidence and mortality of nasopharyngeal carcinoma (NPC) in China in 2010 according to the data of 145 domestic population-based cancer registries in 2014, and no such reports since then. Hence, to further and better understand its epidemiology in China and to provide more precise scientific information for its control and prevention in China, we analyzed the NPC incidence and mortality of 255 domestic population-based cancer registries, and estimated the national rates in 2013 again. Methods: NPC incidence and mortality data of 255 domestic cancer registries in 2013, accepted by the 2016 National Cancer Registry Annual Report, were collected and collated, and the indices of NPC such as the numbers of new cases and deaths, crude rates, age-standardized rates, and truncated rates of incidence and mortality were calculated and analyzed. The incidence and mortality in China and its constituent areas were estimated according to the national population in 2013. Results: An estimated 42,100 new cases and 21,320 deaths were attributed to NPC in China in 2013, accounting for 1.14% of all new cancer cases and 0.96% of all cancer-related deaths that year in China. Crude incidence and mortal-ity of NPC were 3.09/100,000 and 1.57/100,000, respectively. World age-standardized incidence and mortality were 2.17/100,000 and 1.08/100,000, respectively. The incidence and mortality of males were obviously higher than those of females and slightly higher in urban areas than in rural areas. Among seven Chinese administrative regions, NPC incidence and mortality were obviously higher in South China than in other regions and lowest in North China. Top 3 incidence and mortality provinces and registering areas all located in South China. The age-specific incidence and mortality rose quickly from age 25–29 and 35 to 39 years, respectively, peaked at different ages and varied by location. Conclusions: These results demonstrated that NPC incidence and mortality in China in 2013 were also at high levels worldwide, which suggested that its control and prevention should be enhanced.

OBJECTIVETo study the distribution of ScrF1 restriction polymorphism in intron 2 of the 3-hydroxy-3-methylglutaryl coenzyme A(HMG-CoA) reductase gene in Chinese Han population and the association of the polymorphism with coronary heart disease(CHD).

METHODSHMG-CoA reductase genotyping was performed using polymerase chain reaction-restriction fragment polymorphism.

RESULTSHMG-CoA reductase allelic frequencies of A, a were 0.519, 0.481; 0.440, 0.560 in CHD group and control group respectively. There was no significant difference in frequencies of allele and genotype in ScrF1 polymorphism between CHD group and control group(P>0.05). However, the levels of plasma very low density lipoprotein (VLDL) and TG in CHD patients with AA genotype were higher than those in CHD patients with other genotypes(P<0.05). The frequencies of A, a alleles at ScrF1 polymorphic site were significantly different from those reported in European Caucasians (0.44 vs 0.55, 0.56 vs 0.45, P<0.05).

CONCLUSIONNo direct association was found between the ScrF1 polymorphism and CHD, but there is a significant correlation between the AA genotype of the HMG-CoA reductase gene and the levels of plasma VLDL and TG in CHD group.

Liver cancer is a common malignant tumor in China and a major health concern. We aimed to estimate the liver cancer incidence and mortality in China in 2010 using liver cancer data from some Chinese cancer registries and provide reference for liver cancer prevention and treatment. We collected and evaluated the incidence and mortality data of liver cancer in 2010 from 145 cancer registries, which were included in the 2013 Chinese Cancer Registry Annual Report, calculated crude, standardized, and truncated incidences and mortalities, and estimated new liver cancer cases and deaths from liver cancer throughout China and in different regions in 2010 from Chinese practical population. The estimates of new liver cancer cases and deaths were 358,840 and 312,432, respectively, in China in 2010. The crude incidence, age-standardized rate by Chinese standard population (ASR China), and age-standardized rate by world standard population (ASR world) were 27.29/100,000, 21.35/100,000, and 20.87/100,000, respectively; the crude, ASR China, and ASR world mortalities were 23.76/100,000, 18.43/100,000, and 18.04/100,000, respectively. The incidence and mortality were the highest in western regions, higher in rural areas than in urban areas, and higher in males than in females. The age-specific incidence and mortality of liver cancer showed a rapid increase from age 30 and peaked at age 80-84 or 85+. Our results indicated that the 2010 incidence and mortality of liver cancer in China, especially in undeveloped rural areas and western regions, were among high levels worldwide. The strategy for liver cancer prevention and treatment should be strengthened.

Nasopharyngeal carcinoma (NPC) is common in South China. Although regional epidemiological data on NPC in China is available, national epidemiological data have been unavailable up to now. The goal of this study was to analyze the NPC incidence and mortality data in some domestic cancer registries, estimate these rates in China in 2010, and provide scientific information that can be harnessed for NPC control and prevention. To accomplish this goal, NPC incidence and mortality data for 2010 were collected from 145 Chinese cancer registries from which data were included in the 2013 National Cancer Registry Annual Report. Such indices as its incident and death numbers, crude rates, age-standardized rates and truncated rates were calculated and analyzed. The incidence and mortality in China and constituent areas were estimated according to the national population in 2010. An estimated 41,503 new cases and 20,058 deaths were attributed to NPC in China in 2010, accounting for 1.34% of all new cancer cases and 1.03% of all cancer-related deaths that year in China. Crude incidence and mortality were 3.16/100,000 and 1.53/100,000, respectively. World age-standardized incidence and mortality were 2.44/100,000 and 1.18/100,000, respectively. Incidence and mortality were higher among males than among females and slightly higher in urban areas than in rural areas. Among seven Chinese administrative regions, NPC incidence and mortality were obviously higher in South China than in other regions and lowest in North China. The male and female age-specific incidence and mortality both rose quickly from age 25-29 years, but peaked at different ages and varied by location. These results demonstrated that NPC incidence and mortality in China especially in South China were at high levels in the world, and suggested that control and prevention efforts should be enhanced.
