Objective To investigate the feasibility of laparoscopic radical gastrectomy for gastric cancer.Methods Laparoscopic radical gastrectomy was performed in 8 cases from Febrary 2005 to April 2005,including radical distal gastrectomy in 6 cases,radical total gastrectomy in 1 case,and radical proximal gastrectomy in 1 case.Results All the 8 patients underwent laparoscopic radical gastrectomy smoothly and no conversion to open surgery was required.The operation time was 340?62 minutes in radical distal gastrectomy,was 362 minutes in radical proximal gastrectomy,and 423 minutes in radical total gastrectomy.The intraoperative blood loss was 100～250 ml(mean,140 ml) in radical distal gastrectomy,300 ml in radical total gastrectomy,and 170 ml in radical proximal gastrectomy.No blood transfusion was needed.The number of havested lymph nodes was 18～37(mean,23).No surgical-related complications occurred.The time to first flatus was 38～56 hours(mean,42.4 hours),and the time to liquid diet was 2～5 days(mean,2.5 days).All the 8 cases were followed for 12～14 months postoperatively and no recurrence or metastasis was observed.Conclusions Laparoscopic radical gastrectomy is a feasible technique for patients with gastric cancer at early stage or early progressive stage.

0.05). CONCLUSIONS Levofloxacin is suited to prevent and treat the infection during the perioperation of appendectomy due to acute appendicitis.

ObjectiveTo investigate the changes in liver function and the efficacy of either hand-assisted laparoscopic surgery (HALS) or open splenectomy (OS) in combination with pericardial devascularization in the treatment of portal hypertension. MethodsThe clinical data of 94 patients who received splenectomy combined with pericardial devascularization to treat portal hypertension due to cirrhosis from Jan 2002 to May 2008 were analyzed retrospectively. 56 patients received OS and 38patients HALS. The operating time, intraoperative blood loss, postoperative complications, liver dysfunction and mortality were analyzed according to the Child's grading. ResultsThere was no difference in the operating time between HALS and OS (P＞0. 05). The intraoperative blood loss and postoperative complications were 5.6% and 10.8%, respectively (P＜0. 05). There was no significant difference in the serum ALT between HALS and OS, but there was a significant difference in the ALB (P＜0. 05). The AST also had a significant difference on postoperative day 5 (P＜0. 05). The serum ALT and AST were elevated after HALS, but there was a significant difference only for AST (P＜0.05). The serum ALT and AST in OS were significantly higher after than before operation (P＜0. 05). The serum ALB in OS was significantly lower after operation (P＜0.05), but it was significantly lower only on postoperative days 1 and 3 (P＜0.05) in HALS. ConclusionsCompared with OS, HALS combined with pericardial devascularization caused less damage to the intestinal tract and the liver function. It is a feasible and safe operation and it had fewer postoperative complications.

The prognosis of malignant tumors of the digestive system is still a matter of close attention in the medical and health field. At present, evaluating the prognosis of patients with digestive system malignant tumors is mainly based on the TNM staging of the tumor after surgery. As one of the ten characteristics of cancer, inflammatory indicators have certain guiding significance for the prognosis and treatment of patients with malignant tumors of the digestive system. As a new type of inflammation index, the systemic inflammatory response index is significantly better than other traditional inflammatory indexes in evaluating the prognosis of patients with digestive system malignant tumors. This article reviews the related studies on the systemic inflammatory response index in evaluating the prognosis of digestive system malignant tumors.

Objective To explore the clinical value of autologous fat injection with platelet rich plasma in facial rejuvenation.Methods 35 female beauty seekers were collected in this study.They were divided into two groups:sample autologous fat group (FAT group,n=20) and combined autologous fat and platelet-rich plasma group (PRP group,n =15).The average level of injection was 34 ml.The fat was collected at the abdominal or thigh sites using 18 G needle connecting with negative pressure suction-pump.The fat was centrifugated 2 min to get rid of the lower layer of water and the upper layer of oil.Weigao PRP extract kit was used to obtain the PRP.The ratio of PRP to fat was 1:5.The injection technique was according to Colemen method.The survival rate,satisfaction and complication were compared between the 2 groups.Results There were no infection,hematoma,fat liquefaction necrosis occurred in the 2 groups.Compared with the FAT group,the skin texture and facial contour of the PRP group was improved.Conclusions The platelet rich plasma can improve the survival rate of fat and has a stable effect,which is one of the safe and ideal methods of facial rejuvenation.

Objective: To investigate the diagnostic value of 64 multislice spiral CT (64-MSCT) and 1.5T MRI in nurseling with congenital vascular rings.
Methods:We retrospectively studied the diagnostic records of 64-MSCT and 1.5T MRI in 48 nurseling with congenital vascular rings. There were 42 cases received CTA, 12 received MRA and 6 received both CTA and MRA. We classiifed the types of vascular rings by Edwards sketch map of aortic arch embryonic development and trachea wrapping conditions. The diagnostic values of 64-MSCT and 1.5T MRI on vascular rings were compared.
Results: There were 25 patients with complete vascular rings including 3 of double aortic arch, 12 right aortic arch with left subclavian artery and patent ductus arteriosus (PDA), 9 combining with arterial ligament, 1 neck right aortic arch with left subclavian artery combining left PDA;and 23 patients with in-complete vascular rings including 2 pulmonary artery sling, 9 left aortic arch with right subclavian artery combining left PDA, 10 combining with arterial ligament, 1 right aortic arch with left subclavian artery combining right PDA, 1 with innominate artery compressed trachea. There were 32/48 patients combined with cardiac malformations, both 64-MSCT and 1.5T MRI may well reveal the composition and special relationship of vessel rings. The minimum intensity projection (MinIP) and air volume rendering (VR) of 64-MSCT may clearly display the morphology and development of trachea, image fusion technique could directly show the special relationships among vascular rings, trachea and esophagus. While 1.5T MRI was relatively poor to present tracheal image.
Conclusion: 64-MSCT could accurately and comprehensively display the special relationships among the vessels rings, trachea and esophagus;which was the best method for diagnosing the nurseling with vessel rings in clinical practice.

Objective : To investigate the epidemiological characteristics of influenza among the elderly in Heilongjiang Province from 2017 to 2021 (April 2017 to March 2022), so as to provide insights into influenza control among the elderly. Methods : The data pertaining to surveillance of patients with influenza-like illness (ILI) at ages of 60 years and older in Heilongjiang Province from 2017 to 2021 were retrieved from Chinese Influenza Surveillance Information Management, and the temporal distribution of ILI cases and the results of influenza virus tests were descriptively analyzed. Results : Totally 26 908 ILI cases at ages of 60 years and older were reported in Heilongjiang Province from 2017 to 2021, with an ILI prevalence rate of 0.17%. The prevalence of ILI appeared a tendency towards a rise in Heilongjiang Province from 2017 to 2021 (χ2trend=268.554, P<0.001), and the epidemic peaked in the 3rd to 7th weeks of 2019 and 2020. The overall positive rate of influenza virus was 6.80%, and the positive rate of influenza virus showed a tendency towards a decline from 2017 to 2021 (χ2trend=425.268, P<0.001). Influenza A (H1N1) pdm09 (46.82%) and A (H3N2) (22.79%), as well as influenza B virus lineages B/Victoria (12.11%) and B/Yamagata (18.28%) were predominant types, which changes among the study period. The detection of influenza virus-positive samples peaked from December to March of the next year, and a high positive rate of influenza virus was detected in Hegang (12.35%), Heihe (11.47%) and Daqing cities (11.07%). There was no significant correlation between the prevalence of ILI and the positive rate of influenza virus in Heilongjiang Province from 2017 to 2021 (rs=-0.800, P=0.104). Conclusions The prevalence of ILI appeared a tendency towards a rise among the elderly at ages of 60 years and older in Heilongjiang Province from 2017 to 2021, and the epidemic peaked in winter and spring. Influenza A (H1N1) pdm09, A (H3N2), B/Victoria, B/Yamagata were alternately prevalent and there was no obvious correlation between ILI prevalence and the positive rate of influenza virus.

Objective　To explore the changes of ER-IR and the ultra structure in the medial preoptic area, arcuate nuclei of early-aged mice treated with estrogen. Methods　Immunohistochemistry assay and electron microscopy were used in this study. Results　ER-IR in the medical preoptic area and arcuate nuclei were greatly reduced after estrogen was given. The cell nuclei of neurons in these areas migrated towards the side, the nuclear membrane became folded, synapse became richer, and the number of synapse vesicle increased. Conclusion　Estrogen can affect the neuron structure and function through the change of estrogen receptor expression in the medial preoptic area and arcuate nuclei of the hypothalamus cardiovascular center.

Objective:To investigate the feasibility of replacing the femoral prosthesis and implanting antibiotic calcium sulfate carriers in a two-stage revision for periprosthetic infection following total knee arthroplasty (TKA).Methods:Between May 2017 and January 2020, 35 patients were admitted to Department of Orthopaedic Surgery, The First Affiliated Hospital to Zhengzhou University for periprosthetic infection after TKA. They were 12 males and 23 females, aged from 49 to 84 years (average, 67.9 years). The two-stage revision for periprosthetic infection was performed for all of them and replacement of femoral prosthesis and implantation of antibiotic calcium sulfate carriers were carried out in stage-one revision. Recorded were postoperative culture of micro-organisms, white blood cell count (WBC), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) before stage-one and stage-two revisions; the Hospital for Special Surgery (HSS) knee score, range of motion (ROM) and American Knee Society Score (KSS) were compared between preoperation and the last follow-up.Results:Postoperative negative culture was found in 22 cases (62.9%), and positive one in 13 cases (37.1%) of which 4 were caused by Staphylococcus aureus, 2 by Staphylococcus epidermidis, 2 by Candida glabrata, 2 by Candida parapsilosis, one by Candida albicans, one by Mycobacterium tuberculosis and one by Escherichia coli. WBC, ESR and CRP decreased on average from 13.67×10 9/L, 49.71 mm/h and 45.13 mg/L before stage-one revision to 6.44×10 9/L, 18.79 mm/h and 7.82 mg/L before stage-two revision. All patients were followed up for an average of 22.4 months (from 8 to 41 months). At the last follow-up, ROM, HSS and KSS were significantly increased from preoperative 73.2°±15.9°, 59.5±14.6 and 36.1±6.0 to 105.6°±13.2°, 84.3±10.0 and 86.1±5.6, respectively ( P<0.05). None of the patients showed any sign of re-infection at the last follow-up. Conclusion:For patients with periprosthetic infection following total knee arthroplasty, replacing femoral prosthesis and implantation of antibiotic calcium sulfate carriers can well control infection, facilitating recovery of range of motion and function after surgery.
