Objective To observe the clinical efficacy of lesion removal,bone grafting,fusion,and external fixation in the treatment of late-stage wrist tuberculosis.Methods From October 2015 to May 2019,25 patients with late-stage wrist tubercu-losis were treated using lesion removal,bone grafting,fusion,and external fixation.Among these patients,there were 14 males and 11 females,aged from 40 to 74 years old,with an average age of(60.72±8.45)years old.The duration of the disease ranged from 5 to 24 months,with an average of(11.52±7.61)months.There were 11 cases of left wrist tuberculosis and 14 cases of right wrist tuberculosis,with 5 cases accompanied by sinus formation.Postoperative regular anti-tuberculosis treatment was continued.Visual analogue score(VAS),inflammatory indicators,Gartland-Werley wrist function score,and upper limb function score were observed before and after treatment.Results All 25 patients were followed up for ranging from 12 to 36 months with an average of(19.7±6.3)months.At the latest follow-up,all wounds were healed satisfactorily,and there was no recurrence of tuberculosis or infection.VAS at one week before operation and three months after operation were(5.16±1.14)score and(1.68±0.80)score respectively.One week before operation and three months after operation,erythrocyte sedimenta-tion rate(ESR)was(44.20±20.56)mm·h-1 and(14.44±1.14)mm·h-1,and C-reactive protein(CRP)was(12.37±7.95)mg· L-1and(4.3±3.37)mg·L-1.The differences in all three data sets were statistically significant(P＜0.01).According to Gartland-Werley wrist function scoring,the scores at one week before operation and one year after operation were(21.32±3.44)and(14.96±1.37)respectively,showed a statistically significant difference(P＜0.01).According to the upper limb function score(disabilities of the arm,shoulder,and hand,DASH),the score was(70.52±7.95)at one week before operation and(28.84± 2.30)at one year after operation.The difference was statistically significant(P＜0.01).At the latest follow-up,no patient had a recurrence of tuberculosis.Conclusion The short-term clinical efficacy of treating wrist tuberculosis with lesion removal,bone grafting,fusion,and external fixation is satisfactory.

SARS-CoV-2 Omicron variant (B.1.1.529) was first discovered in South Africa in November 2021 and has since become a mainstream strain worldwide. Omicron variant was defined as the fifth "variant of concern (VOC)" by World Health Organization on November 26, 2021. This paper illustrates the mutation trends of Omicron variants in terms of SARS-CoV-2 genome and protein structure as well as nucleic acid site mutations and amino acid site mutations, describes the features of Omicron mutation sites in terms of lineage comparison among the VOCs and Omicron sublineages, and further highlights the influences of Omicron site mutations from the aspects of immune escape, virulence and transmission ability. Moreover, this paper also reviews the development of direct antiviral agents, antibodies and vaccines, aiming to provide reference for further investigation.

Objective:To investigate the effect of early postoperative enteral nutrition(EN)on postoperative rehabilitation and inflammation after laparoscopic radical gastrectomy for gastric cancer,in order to provide reference for postoperative rehabilitation of such patients.Methods:Patients who received laparoscopic assisted radical gastrectomy in Department of Gastrointestinal Surgery of The First Affiliated Hospital of Bengbu Medical College from January 2020 to December 2022 were included in the analysis.According to the different ways of postoperative nutritional treatment,patients were divided into the observation group(early postoperative EN group)and the control group(parenteral nutrition group),and indexes such as postoperative rehabilitation,abdominal drainage flow and the level of inflammatory mediators in drainage fluid were compared between the two groups.Results:A total of 81 patients were included,including 41 in the observation group and 40 in the control group.Interval of the first postoperative exhaust(t=3.806;P＜0.001)and resuming diet day(t=5.510;P＜0.001),and length of postoperative hospital stay(t=2.401;P=0.019)in the observation group were shorter than those in the control group.Levels of peripheral blood albumin(t=14.040;P＜0.001)and prealbumin(t=9.832;P＜0.001)of the observation group at postoperative day(POD)5 were significantly higher than those of the control group,but there was no significant difference in hemoglobin level(t=1.477;P=0.144).The level of CRP in peripheral blood of the observation group at POD 5(t=7.758;P＜0.001)and the incidence of postoperative SIRS[(12.2％,5/41)vs(32.5％,13/40),x2=4.830;P=0.028)]were significantly lower than those in the control group.The average drainage volume(t=6.858;P＜0.001),drainage removal time(t=5.016;P＜0.001),and TNF-α level(t=4.993;P＜0.001)and IL-6 level(t=20.640;P＜0.001)in postoperative drainage at POD 5 were significantly lower in the observation group than those in the control group.Conclusion:Early postoperative EN could accelerate the rehabilitation process after laparoscopic radical gastrectomy,improve postoperative nutritional status,and reduce abdominal inflammation.

OBJECTIVE: To investigate the expression and clinical significance of soluble interleukin-2 receptor(sIL-2R) in patients with multiple myeloma(MM). METHODS: 54 newly diagnosed MM patients in the Second Affiliated Hospital of Fujian Medical University from February 2020 to December 2021 were selected as the observation group, and 60 healthy people in our hospital in the same period were selected as the control group. The expression levels of sIL-2R in the serum of the two groups were detected by enzyme-linked immunosorbent assay. The differences of sIL-2R expression level among different clinical parameter groups in MM patients were compared. The clinical parameters include:gender, age, ISS stage, hemoglobin, albumin, serum creatinine, lactate dehydrogenase and β₂-microglobulin, blood calcium, bone marrow plasma cell ratio and treatment response. The relationship between sIL-2R expression level and progression-free survival(PFS) and overall survival(OS) in MM patients were analyzed. RESULTS: The expression of serum SIL-2R in MM patients was significantly higher than that in healthy control group (P<0.05). The expression of sIL-2R in MM patients who did not achieve complete remission(CR) was significantly higher than those of CR patients (P=0.037). There was no significant difference in the expression of serum sIL-2R between the groups of different sex, age, ISS stage, hemoglobin concentration, albumin content, serum creatinine level, lactate dehydrogenase level, the content of β₂-microglobulin, the concentration of blood calcium, and the proportion of bone marrow plasma cells(P>0.05). The PFS of sIL-2R high expression group(15 months) was shorter than that of sIL-2R low expression group (22 months), which was significant difference (P=0.041). But there was no significant difference in OS between sIL-2R high expression group and sIL-2R low expression group (P=0.124). Univariate analysis results showed that the high expression of serum sIL-2R was associated with poor PFS in MM patients. Multivariate analysis results showed that the high expression of serum sIL-2R was still an independent adverse prognostic factor for PFS in MM patients, However, the expression of serum sIL-2R was not statistically significant in evaluating OS in MM patients by univariate and multivariate analysis. CONCLUSION The expression of serum sIL-2R in MM patients was significantly higher than that in healthy people. Serum sIL-2R is an independent prognostic factor of PFS in MM patients.

OBJECTIVE: To analyze the influence of preoperative serum nutritional indexes and postoperative nutritional guidance on 1-year mortality in elderly patients with hip fracture. METHODS: From January 2015 to December 2017, 396 elderly patients with hip fracture were included in the study, including 267 females and 129 males, aged 68 to 80(75.48±2.62) years; the course of disease was 2 to 10 (6.12±1.35) days;all patients were followed up for 1-year, and were divided into death group and survival group according to whether the patients died or not. Multivariate logistic regression model was used to analyze the influencing factors of 1 year mortality. RESULTS: Duringthe follow-up, 4 patients lost contact and were treated as shedding, among which 67 patients died and 325 patients survived. The age, male patients, patients with more than three basic diseases, American Society of Anesthesiologists grade Ⅲ-Ⅳ and patients with postoperative complications in the death group were significantly higher than those in the survival group (all CONCLUSION Advanced age, male and multiple underlying diseases were independent risk factors for 1-year mortality in elderly patients with hip fracture, while higher preoperative nutritional level and routine nutritional guidance were protective factors.
