Objective To study the effect and mechanism of antisense oligodeoxynucleotides (ASONs) inhibiting hepatitis B virus (HBV) expression. Methods We designed and synthesized antisense oligodeoxynucleotides directly against HBV PreS 2 gene and noncomplementary sequence control. 2.2.15 cells were chosen as cell model. Inhibitory effect of ASONs on HBV gene expression were assayed by ELISA. Cell apoptosis and proliferation were detected by Fascan Flow Cell Cytometer. Effect of ASONs on cell metabolism was detected by radioimmunoassay (RIA) and MTT assay. Results ASONs were able to effectively inhibit HBV expression. Their inhibitory rates of HBsAg and HBeAg were 66% and 91%, respectively. Noncomplementary sequence control group (both inhibitory rates were 11%) was not able to inhibit HBV expression. ASON might induce host cell apoptosis. Cell apoptosis rates on 3rd and 6th day were 6.10% and 6.43%, respectively. Proliferation index were 37% and 36%, respectively. Results of RIA and MTT showed that ASON had not cytoxicity on host cell. Conclusions Not only are ASON able to inhibit HBV gene expression with sequence specific but also clear HBV in the way of apoptosis.

Objective To provide better emergency and patient services in well-equipped comprehensive hospitals, the organization and wisdom therapeutic strategy are of great importance for the recovery of injured patients from the earthquake zone. Method From 12 May 2008, following the 8.0 Magnitude earthquake in Wenchuan county of Sichuan Province, six Chongqing hospitals with third class in grade A were involved in the rescue of the injured patients with great effort. A total of 533 patients were retreated and followed up from quake zone. All the patients were scored with ISS and AIS system. The profiles of the patients examined, operated and clinical infection investigation were documented. Results Of 533 patients, the number of the patients whose ISS is below 16 is 456 (83.6%), the number between 16 and 25 is 65 (12.2%), and the humor above 25 is 12 (2.3%). The patients were classfled based on their fracture parts as follows: head and neck (n = 42), face (n = 7), chest (n = 114), abdominal and cavitas pelvis (n =81), limb and pelvis (n =314), body surface (n =205), with 180 single fracture site, 139 of them being two combined fracture sites, and 114 of them being above three combined fracture sites. Thirty-two of the patients were suffered from amputation. The number of patients suffered from crushing syndrome reached 21, with 281 surgical operations in hospitals. Seventy-nine patients were suffered from infections including 87.3% of pre-hespital infections. The results from bacteria culture and antibiotic susceptibility showed that the infected bacteria mainly involved in Escherichia coli, Staphylococcus anreus, Staphylococcus haemolyticns, Klebsiella pneumoniae, Baumanii, Aerobacter cloacae, Pseudomonas aeruginosa, C type chain coccus, Bacillus aerogenes capsulatus. The antibiotic susceptibility to diverse bacteria has no obvious changes and exists partial overlapping, and infected patients should be given the treatment of cephalosporin, macrolide antibiotic and so on. Conclusions For the emergency conditions after the catastrophe, the comprehensive hospitals must be prepared to meet large quantities of severe trauma and infection therapy. The scientific selection of antibiotics in the combinative therapy is of great importance to the enhancement of early specific treatment, prevention of severe trauma complications and rehabilitation of patients.

Objective To compare the efficacy and safety of induction therapy in 3+7 protocol and 3+10 protocol in children with acute myeloid leukemia (AML). Methods Two protocols were carried out in our hospital during January 2010 to January 2015, namely 3+7 protocol(AML-06,A group) and 3+10 protocol (modified AML protocol, B group). A total of 56 cases aged from 1 year-old to 13 year-old were enrolled in A group with male to female ratio at 31:25. Five of them were classified as FAB M1, 25 as M2, 11 as M4, 10 as M5, 2 as M6 and 3 as M7. Another 44 cases aged from 1 year to 12 years were enrolled in B group with a male to female ratio at 26:18, and 17 cases were classified as FAB M2, 14 as M4, 9 as M5, 2 as M6, and 2 as M7. Efficacy and adverse events were compared between the two groups. Results The complete remission rate (CR) of B group was 70.4%, while CR in A group was 48.2%. Considering the CR, 3+10 protocol showed higher efficacy than 3+7 protocol (P< 0.05). The major adverse event was bone marrow suppression. Treatment-related mortality (TRD) in A group was 1.8%, which was lower than that in B group (2.3%). The overall survival rate in A group was 75.0%, which was lower than that in B group (86.4%, P< 0.05). Conclusions The induction therapy of 3+10 protocol and 3+7 protocol showed effectiveness for AML treatment. The 3+10 protocol showed a higher CR than 3+7 protocol with no TRD increase, indicating that the 3+10 protocol should be recommended for AML treatment in children.

Objective:Clinical characteristics and diagnosis and treatment process was reported and analyzed of a patient with brucellosis complicated with thyroid abscess, providing reference for the clinical diagnosis of brucellosis complicated with thyroid abscess.Methods:Clinical medical records of a patient with brucellosis complicated with thyroid abscess who was treated at the General Surgery Department of Yanchi County People's Hospital in Wuzhong City, Ningxia Hui Autonomous Region in November 2021 were collected. The clinical manifestations, blood routine, brucella antibodies, thyroid function, bacterial culture, thyroid ultrasound and other examination results, as well as the diagnosis and treatment process, were comprehensively analyzed. Results:The patient was a male, 61 years old, who presented with a neck mass without typical clinical manifestations of brucellosis. Thyroid ultrasound revealed a space occupying lesion, and the preliminary diagnosis was thyroid cystadenoma. Thyroid right lobe and isthmus resection surgery was performed. During the operation, it was found that some of the thyroid glands were tightly adhered to the cervical blood vessels, so the resection surgery was changed to abscess drainage, and the drainage fluid was purulent and bloody. The bacterial culture result of thyroid purulent fluid (intraoperative puncture fluid and postoperative drainage fluid) was brucella lamblia, and the serum brucella test tube agglutination test titer was 1 ∶ 400 (+++). The patient improved and was discharged after local drainage and anti brucella treatment. Follow up for 4 months showed no abnormalities. Conclusions:Brucellosis which begins with a local infection of the thyroid gland is extremely rare, with no characteristic clinical manifestations, and is prone to misdiagnosis. Timely correction of the surgical plan during the treatment process avoids the removal of the patient's thyroid, which has a certain clinical reference value.

METHODSSixty patients with menopausal syndrome of liver-kidney deficiency type were randomly divided into an acupoint stimulation group and a medication group, 30 cases in each group. The patients in the acupoint stimulation group were treated by acupoint catgut embedding at Taixi (KI 3), Sanyinjiao (SP 6), Shenshu (BL 23), Ganshu (BL 18) and Taichong (LR 3), combined with auricular point pressure at Gan (CO), Shen (CO), Neifenmi (CO), Shenmen (TF), Pizhixia (AT); the treatment was given once a week for consecutive four weeks. The patients in the medication group were treated with oral administration of nilestriol, 1 mg, once a day, combined with oral administration of oryzanol, 20 mg, three times per day for consecutive four weeks. The clinical symptom score was compared between the two groups before and after treatment as well as in follow-up visit. The level of Ewas obserced before and after treatment, and the clinical effect was compared.
RESULTS(1) Compared before treatment, the clinical symptom score in the two groups was significantly reduced after treatment and in follow-up visit (all<0.05); In follow-up visit, the clinical symptom score in the acupoint stimulation group was significantly lower than that in the medication group (<0.05). The different value before treatment and at follow-up in the acupoint stimulation group was better than that in the medication group (<0.05). (2) Compared before treatment, the level of Ein the two groups were increased after treatment (both<0.05); compared before and after treatment, the difference in the treatment group was significantly higher than that in the medication group (<0.05). (3) After treatment, the total effective rate was 93.33% (28/30) in the acupoint stimulation group, which was similar to 90.00% (27/30) in the medication group (P>0.05).
CONCLUSIONSCompared with nilestriol, acupoint catgut embedding combined with auricular point pressure with beans could better improve clinical symptoms for patients with menopausal syndrome of liver-kidney deficiency type, and increased the level of E.

The clinical data of 820 cirrhotic portal hypertension patients who were admitted to 21 medical centers in Niangxia region from January 2018 to December 2020 were collected, including 85 cases in Ningxia Hui Autonomous Region People′s Hospital, 73 cases in the Fifth People′s Hospital of Ningxia Hui Autonomous Region, 59 cases in the Wuzhong People′s Hospital, 52 cases in the Qingtongxia People′s Hospital, 50 cases in the Guyuan People′s Hospital, 47 cases in the Yuanzhou District People′s Hospital of Guyuan City, 47 cases in the Yinchuan Second People′s Hospital, 40 cases in the General Hospital of Ningxia Medical University, 40 cases in the Tongxin People′s Hospital, 35 cases in the Yinchuan First People′s Hospital, 34 cases in the Third People′s Hospital of Ningxia Hui Autonomous Region, 32 cases in the Zhongwei People′s Hospital, 30 cases in the Lingwu People′s Hospital, 30 cases in the Wuzhong New District Hospital, 30 cases in the Yanchi People′s Hospital, 29 cases in the Ningxia Hui Autonomous Region Academy of Traditional Chinese Medicine, 28 cases in the Shizuishan Second People′s Hospital, 25 cases in the Shizuishan First People′s Hospital, 21 cases in the Haiyuan People′s Hospital, 20 cases in the Pengyang People′s Hospital, 13 cases in the Longde People′s Hospital. There were 538 males and 282 females, aged (56±13)years. Observation indicators: (1) clinical charac-teristics of cirrhotic portal hypertension patients; (2) overall prevention and treatment of EVB in cirrhotic portal hypertension patients; (3) prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Results:(1) Clinical characteristics of cirrhotic portal hypertension patients: of 820 cirrhotic portal hypertension patients, 271 cases were in compensated stage and 549 cases were in decompensated stage. Of the 271 cases in compensated stage, there were 183 maels and 88 females, aged (53±12)years. There were 185 Han people, 85 Hui people and 1 case of other ethic group. The etiological data of liver cirrhosis showed 211 cases of viral hepatitis B, 4 cases of alcoholic liver disease, 8 cases of viral hepatitis C, and 48 cases of other etiology. There were 235 cases of Child-Pugh grade A and 36 cases lack of data. Of the 549 cases in decompensated stage, there were 355 males and 194 females, aged (57±14) years. There were 373 Han people, 174 Hui people and 2 cases of other ethic group. The etiological data of liver cirrhosis showed 392 cases of viral hepatitis B, 33 cases of alcoholic liver disease, 10 cases of viral hepatitis C, and 114 cases of other etiology. There were 80 cases of Child-Pugh grade A, 289 cases of grade B, 170 cases of grade C and 10 cases lack of data. (2) Overall prevention and treatment of EVB in cirrhotic portal hypertension patients: of 271 patients in compensated stage, 38 cases received non-selective β-blocker (NSBB) therapy, 16 cases received endoscopic treatment, 6 cases received interventional therapy. Of 549 patients in decompensated stage, 68 cases received NSBB therapy, 46 cases received endoscopic treatment, 28 cases received interventional therapy. (3) Prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals: of 271 patients in compensated stage, 181 cases came from tertiary hospitals, of which 28 cases received NSBB therapy, 15 cases received endoscopic treatment, 6 cases received interventional therapy. Ninety cases came from secondary hospitals, of which 10 cases received NSBB therapy, 1 cases received endoscopic treatment. There was no significant difference in NSBB for prevention of EVB between tertiary and secondary hospitals ( χ2=0.947, P>0.05), while there was a significant difference in endoscopic treatment for prevention of EVB between tertiary and secondary hospitals ( χ2=5.572, P<0.05). Of 549 patients in decompensated stage, 309 cases came from tertiary hospitals, of which 22 cases received NSBB therapy, 29 cases received endoscopic treatment, 22 cases received interventional therapy. Two hundreds and fourty cases came from secondary hospitals, of which 46 cases received NSBB therapy, 17 cases received endoscopic treatment, 6 cases received interven-tional therapy. There were significant differences in NSBB and interventional therapy for prevention of EVB between tertiary and secondary hospitals ( χ2=18.065, 5.956, P<0.05). Conclusions:The proportion of receiving EUB prevention in cirrhotic portal hypertension in Ningxia is relatively low. For patients with compensated liver cirrhosis, the proportion of NSBB therapy and endoscopic treatment in the secondary hospitals was lower than that in tertiary hospitals. For patients with decompensated liver cirrhosis, the proportion of interventional treatment in secondary hospitals is lower than that of tertiary hospitals, but the proportion of NSBB in secondary hospitals taking is higher than that of tertiary hospitals.
