RESUMEN
A 57-year-old male patient was referred to our department with complaints of his right adrenal gland occupancy and hypertension about 6 months. When admitted to the hospital, the blood pressure was about 160/100 mmHg, and the heart rate was 110 beats/min. He was no obvious obesity, acne, abnormal mood, without weakness of limbs, acral numbness, palpitation and headache. He presented with type 2 diabetes for more than 3 years, with oral administration of metformin enteric coated tablets and subcutaneous injection of insulin glargine to control blood glucose, and satisfied with blood glucose control. Enhanced CT showed that: the right adrenal gland showed a kind of oval isodense, slightly hypodense shadow, the edge was clear, lobular change, the size was about 5.8 cm×5.4 cm, uneven density, there were nodular and strip calcification, round lipid containing area and strip low density area, and the CT value of solid part was about 34 HU. Enhanced scan showed heterogeneous nodular enhancement in the solid part of the right adrenal gland, nodular enhancement could be seen inside. The CT values of solid part in arterial phase, venous phase and delayed phase were 45 HU, 50 HU and 81 HU, respectively. Considering from the right adrenal gland, cortical cancer was more likely. No obvious abnormality was found in his endocrine examination. After adequate preoperative preparation, retroperitoneal laparoscopic adrenalectomy was performed under general anesthesia. During the operation, the 6 cm adrenal tumor was closely related to the inferior vena cava and liver, and after careful separation, the tumor was completely removed and normal adrenal tissue was preserved. The operation lasted 180 min and the blood loss was 100 mL, and the blood pressure was stable during and after the operation. There was no obvious complication. The results of pathological examinations were as follows: the size of the tumor was 7.5 cm×6.0 cm×3.5 cm, soft, with intact capsule and grayish-red cystic in section. Pathological diagnosis: (right adrenal gland) cavernous hemangioma, secondary intravascular thrombosis, old hemorrhagic infarction with calcification and ossification. After 6 months of observation, no obvious complications and tumor recurrence were found. In summary, cavernous hemangioma of adrenal gland is a rare histopathological change. Its essence is a malformed vascular mass. Blood retention is the cause of thrombosis and calcification in malformed vessels. The imaging findings were inhomogeneous enhancement of soft tissue masses, and the adrenal function examination showed no obvious abnormalities. Retroperitoneal laparoscopic surgery is feasible after adequate preoperative preparation. It is difficult to diagnose the disease preoperatively and needs to be confirmed by postoperative pathology.

Objective To analyze the epidemic trend of hepatitis B virus (HBV) in 18 minority nationalities in Yunnan Province from 2009 to 2018, so as to explore the ethnic differences in the incidence of HBV in Yunnan Province. Methods Based on the reported incidence data of hepatitis B in China's disease prevention and control information system from 2009 to 2018, descriptive epidemiology method was used to describe and analyze the incidence of hepatitis B in different ethnic groups, and K-means clustering method was used to explore and analyze the annual average incidence of hepatitis B in different ethnic groups. Results From 2009 to 2018, the average incidence of hepatitis B in Yunnan Province was 44.26/100 000, which was much lower than the overall level of China every year; the average incidence of hepatitis B in ethnic groups was 41.27/100 000, slightly lower than the overall level of Yunnan every year. The prevalence of hepatitis B was different in different ethnic groups. The average incidence of Wa was significantly higher than others (95.26/100 000), and Jingpo was the lowest (22.51/100 000). According to the incidence of hepatitis B, different ethnic groups were divided into three categories: high incidence ethnic group, middle incidence ethnic group and low incidence ethnic group. Conclusion There are ethnic differences in the incidence of hepatitis B in Yunnan Province. The incidence of hepatitis B in some ethnic groups is higher than that in the whole country all the year round, which is the key population in the prevention and control of hepatitis B.
RESUMEN
To find out epidemiological feature of paralytic cases caused by type 2 vaccine-derived poliovirus (VDPV) and the excretion status of the case and to explore the enterovirus infection status among healthy children under five years old around the case in Zhaotong city, Yunnan Province in 2010. Field epidemiological studies at the epidemic area were conducted and a total of 108 stool samples were collected, three from the case, seven from the close contacts and 98 from the healthy children. VDPV was not isolated again from the case; Sabin-like PV strains or VDPV were not isolated from the close contacts and the healthy children; An active search for acute flaccid paralysis cases was conducted in the area, which indicated that the VDPV did not cause virus circulation in local area. Twenty one (20.0%) NPEVs were isolated from 105 stool samples. Among the 21 NPEV isolates, 11 isolates (52.4%) were HEV-A (3 serotypes), 10 isolates (47.6%) were HEV-B (4 serotypes).

Molecular typing was conducted according to the reported method for one HBsAg positive carrier who had a physical examination in Yunnan Province. The S gene of this HBV sample was amplified by nested PCR and the PCR products were directly sequenced. Blast searching was done on the Genbank database and the sequence were compared with the HBV reference sequences in database. The phylogenetic tree was constructed. Homology analysis of nucleotide and smino acid were performed between the sequences from the sample and the reference sequences corresponding to HBV genotype A to I. Analysis of nucleotide and amino acid identities suggested that the sample belonged to HBV genotype I. The HBV genotype I is the first reported in China.

<p><b>OBJECTIVE</b>To know genotypes and serotypes of hepatitis B virus (HBV) detected from hepatitis B infected people in Yunnan Province.</p><p><b>METHODS</b>Serum samples were collected from HBsAg carriers detected from people who had a physical examination at Yunnan Provincial Center for Disease Control and Prevention. The S genes of HBV were amplified by nested PCR and the PCR products were sequenced. The viral genotype was identified by phylogenetic analysis. 27 reference sequences corresponding to HBV genotype A to I were obtained from GenBank. According to the amino acid sequences deduced from the nucleotide sequences of S gene, the dominant serotype of HBV detected from these people were confirmed.</p><p><b>RESULTS</b>39 HBsAg positive serum samples were detected from 2216 people who had a physical examination. The results shows that 76.9% were C genotype; 15.4% were B genotype; 5.1% were D genotype; 2.5% were I genotype. Three serotypes were found. The rates of adw2, adrq+ and ayr serotypes are 71.8%, 17.9% and 10.3% respectively. All of adw2 subtype specimens are C genotype. Among the serum specimens in which both HBsAg and HBeAg are positive, 75% were C genotype and adw2 subtype.</p><p><b>CONCLUSION</b>It is determined that the main genotype and subtype of HBV prevailed in Yunnan province is C genotype and adw2 subtype.</p>
