OBJECTIVE: To explore short-term clinical efficacy of minimally invasive diagnosis and treatment system for hallux valgus in guiding the treatment of hallux valgus. METHODS: From March 2021 to November 2023, 68 patients (136 feet) with hallux valgus were treated under guidance of minimally invasive diagnosis and treatment system, including 12 males and 56 females;aged from 25 to 68 years old with an average of (42.5±8.5) years old, the course of disease ranged from 3.2 to 15.6 years with an average of (10.3±2.6) years. The changes of hallux valgus angle (HVA) and intermetatarsal angle (IMA), visual analog scale (VAS) and American Orthopaedic Foot Ankle Society (AOFAS) forefoot score were recorded and compared before operation and 12 months after operation. RESULTS: Sixty-five patients (130 feet) were followed up for 12 to 15 months with an average of (13.8±0.5) months, 3 patients (6 feet) were not followed up as required. HVA and IMA improved from (35.5±3.5) ° and (12.5±2.0) ° before operation to (10.5±2.5) ° and (8.5±1.5) °12 months after operation, respectively, with statistically significant differences (P<0.05);VAS decreased from (5.5±1.2) before operation to (1.2±0.5) at 12 months after operation, and the difference was statistically significant (P<0.05);AOFAS forefoot score increased from (50.6±5.1) before operation to (93.8±5.6) at 12 months after operation, with a statistically significant difference (P<0.05). Among them, 102 feet were got excellent result, 24 feet good, and 4 feet fair. Two patients were developed calf intermuscular vein thrombosis, and were cured after 3 months of symptomatic treatment. CONCLUSION Under the guidance of minimally invasive diagnosis and treatment system for hallux valgus, the treatment of HV could obviously improve HVA and IMA, and significantly alleviate pain symptoms, and accelerate functional recovery.

Purpose: We evaluated the therapeutic effects on overactive bladder (OAB) symptoms and sexual function of behavioral therapy with or without mirabegron in sexually active male patients with OAB. Mirabegron, a selective β3 adrenoceptor agonist for the treatment of OAB, has been shown to induce corpus cavernosum relaxation. Methods: In this 4-site, randomized controlled trial, 150 sexually active men with OAB were enrolled between June 2020 and May 2022. Participants were randomly allocated (1:2) into 2 treatment groups: (1) behavioral therapy alone (n = 50) and (2) a combination of mirabegron 50 mg daily and behavioral therapy (n = 100). The evaluation was based on the overactive bladder symptoms score (OABSS), the International Index of Erectile Function, the ejaculatory domain short form, the International Prostate Symptom Score, patient perception of bladder condition, quality of life, and urodynamic parameters. The therapeutic outcomes were assessed at baseline, 4 weeks, and 12 weeks. Results: There were 65 patients (65%) in the combination subgroup and 36 patients in the behavioral therapy who completed all 12 weeks of treatment. Both groups had a statistically significant improvement in OABSS after 12 weeks of treatment. The combination therapy group achieved a statistically significant improvement in all 4 subscores of OABSS, however, the urinary frequency (P = 0.120) and urinary incontinence (P = 0.234) subscores in the behavioral therapy only group did not show a significant change. Additionally, the combination group had a significant improvement in functional bladder capacity, which was not seen in the behavioral therapy group. However, both groups did not have a significant change in erectile or ejaculatory function. Conclusions Behavioral therapy combined with mirabegron had more significant impact on the improvement of OAB than behavior therapy alone. However, both groups did not have significant changes in erectile or ejaculatory function.

By a orthogonal experiment, the influence of different ratio of phosphorus and potassium fertilizers on imperatorin, isoimperatorin and psoralen contents and yield of Glehnia littoralis were studied. The results showed that root dry weight and the yield of G. littoralis increased when reasonably applied phosphorus fertilizer combined with potassium fertilizer within a certain range. And the influence of phosphorus fertilizer was greater than that of potassium fertilizer. The optimal value of root dry weight and yield achieved at both P2O5 360 kg x hm(-2), K2O 270 kg x hm(-2) and P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2). The effects of different phosphorus and potassium treatments on the content of imperatorin, isoimperatorin and psoralen in G. littoralis were determined, which shows that the content increased with the moderate increase of phosphorus and potassium. And the effects of phosphorus fertilizer were more significantly. The isoimperatorin content achieved the largest value at P2O5 360 kg x hm(-2), K2O 270 kg x hm(-2), also a larger content of imperatorin and psoralen. The imperatorin content is the largest when applied P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2), and the isoimperatorin content was higher as well. So that the treatment of P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2) are suitable for promote to the agricultural production, which could improve the quality and yield of G. littoralis.

BACKGROUNDPancreaticogastrostomy (PG) has been proposed as an alternative to pancreaticojejunostomy (PJ), assuming that postoperative complications are less frequent. The aim of this research was to compare the safety of PG with PJ reconstruction after pancreaticoduodenectomy.

METHODSArticles of prospective controlled trials published until the end of December 2010 comparing PJ and PG after PD were searched by means of MEDLINE, EMBASE, Cochrane Controlled Trials Register databases, and Chinese Biomedical Database. After quality assessment of all included prospective controlled trials, meta-analysis was performed with Review Manager 5.0 for statistic analysis.

RESULTSOverall, six articles of prospective controlled trials were included. Of the 866 patients analyzed, 440 received PG and 426 were treated by PJ. Meta-analysis of six prospective controlled trials (including RCT and non-randomized prospective trial) revealed significant difference between PJ and PG regarding postoperative complication rates (OR, 0.53; 95%CI, 0.30 - 0.95; P = 0.03), pancreatic fistula (OR, 0.47; 95%CI, 0.22 - 0.97; P = 0.04), and intra-abdominal fluid collection (OR, 0.42; 95%CI, 0.25 - 0.72; P = 0.001). The difference in mortality was of no significance. Meta-analysis of four randomized controlled trials (RCT) revealed significant difference between PJ and PG regarding intra-abdominal fluid collection (OR, 0.46; 95% CI, 0.26 - 0.79; P = 0.005). The differences in pancreatic fistula, postoperative complications, delayed gastric emptying, and mortality were of no significance.

CONCLUSIONSMeta-analysis of six prospective controlled trials (including randomized controlled trials (RCT) and non-randomized prospective trial) revealed significant difference between PJ and PG regarding overall postoperative complications, pancreatic fistula, and intra-abdominal fluid collection. Meta-analysis of four RCT revealed significant difference between PJ and PG with regard to intra-abdominal fluid collection. The results suggest that PG may be as safe as PJ.

Objective To develop a BP26 recombinant BCG (rBCG-BP26) vaccine,and to observe the effects of rBCG-BP26 on CD4+,CD8+ T cells in immunized mice.Methods The recombinant shuttle vector pMV261-Ag85B-BP26 was constructed by using traditional molecular biological technology.The recombinant strains were obtained by kanamycin resistance screening and PCR identification after electroporation.Western blotting was used to detect the expression of recombinant BP26 vaccine in immunized mice.Safety experiment was carried out in three different groups:the target experiment(rBCG-BP26) group,the positive control(BCG) group and the negative control(PBS) group,15 BALB/c mice in each group.Intradermal inoculations of 100 μl rBCG-BP26 [containing 106 colony forming units(CFU)],BCG,and PBS were carried out,respectively.Signs of mice in each group were observed.After immunization for 10,20,30,and 40 days,body weight was weighed,and tail blood was collected to observe the change of peripheral blood CD4+ and CD8+ T cells by flow cytometry.Results The rBCG-BP26 was successfully constructed.The expression of BP26 protein was detected in the liquid medium and the bacteria cells.The results of safety test analysis showed that there were no significant differences in signs and body weights(F=2.468,0.331,1.520,0.739,all P＞ 0.05),between PBS group[ (19.24 ± 0.54),(21.37 ± 0.66),(22.83 ± 0.62),(25.06 ± 0.37)g],BCG group[ (19.90 ± 0.02),(21.53 ± 1.57),(21.95 ± 0.55),(24.70 ± 0.39)g]and rBCG-BP26 group[ (19.16 ± 0.55 ),(20.89 ± 0.20),(22.15 ± 0.76),(24.60 ± 0.64)g].The results of flow cytometry showed that the percentages of CD4+ T cell level were lower in BCG group(26.70％,33.07％) and rBCG-BP26 group( 13.40％,26.70％) than that of the PBS group(33.85％,29.33％) and the values of CD4+/CD8+ T cells increased in rBCG-BP26 group (0.69％,1.27％,1.57％,1.70％ ) 10,20 and 30 days after immunization.Conclusions Recombinant BCG-BP26 vaccine strain can express brucella BP26 protein efficiently.Furthermore,its virulence is mild,and it can activate CD4+,CD8+ T cells in the body.It can be used as one of candidate vaccine strain against brucellosis.

OBJECTIVETo explore whether neutrophil-lymphocyte ratio (NLR) is an effective prognostic marker in gastric cancer.

METHODSClinical data of 775 patients with gastric cancer in the First Affiliated Hospital of Sun Yat-sen University from 1994 to 2006 were analyzed retrospectively. According to preoperative NLR, the patients were divided into the low NLR group (NLR≤3.79, n=652) and the high NLR group (NLR>3.79, n=123). The 5-year survival rates of two groups of different TNM stage, different surgical intervention were separately analyzed.

RESULTSThe 5-year survival rates in the low NLR group and high NLR group were 44.0% and 12.2% respectively (P<0.01). In different TNM stages: stage I (97.8% vs 33.3%), stage II (55.4% vs 32.0%), stage IIIA (30.2% vs 11.1%), stage IIIB (15.5% vs 8.3%), stage IV (10.7% vs 2.1%), and in different surgical intervention: D1 curative gastrectomy (93.3% 33.3%), D2 group (51.3% vs 20.4%), D3 group (42.4% vs 10.5%), D4 group (14.3% vs 2.0%), and in palliative operation group (8.3% vs 2.2%). There were significant differences of 5-year survival rate in TNM staging and surgical procedures between the high and low NLR groups (all P<0.05).

CONCLUSIONPreoperative NLR may be a prognostic marker in patients with gastric cancer.

Background and Objective: Treatment planning for radiotherapy of upper thoracic esophageal carcinoma is challenging due to the anatomical features. The difficulty may be resolved by intensity-modulated radiotherapy (IMRT).This study was to compare the dosimetric advantages of IMRT to that of conformal radiotherapy (CRT) for upper thoracic esophageal carcinoma, and to explore the clinical application of IMRT. Methods: Eleven patients with upper thoracic esophageal carcinoma were enrolled. In addition to the actually used CRT plan,a five-field IMRT plan was generated for each case. The parameters of dose volume histogram for targets and organs at risk were compared between two techniques. Results: For the planning target volume (PTV) of tumor and para-tumor tissues, the mean dose, maximal dose, doses covering 99% and 95% volume were similar in IMRT and CRT plans (P＞0.05). However, IMRT plan had a higher conformity index than CRT plan (0.68 ±0.04 vs. 0.46 0.11, P＜0.01). For the PTV of supraclavicular region, IMRT plan showed a better dose heterogeneity index than CRT plan (1.17 0.05 vs. 1.33 0.15, P=0.01). IMRT plan had lower maximal dose to the planning risk volume of the spinal cord (44.4 Gy vs, 52.5 Gy, P＜0.05) and lower lung volume received dose of 10 Gy or higher [(32 6)%vs. (35 9)%, P＜0.05] than CRT plan. Conclusion: For the upper thoracic esophageal carcinoma,IMRT has more conformal distribution of dose and better spinal cord sparing than CRT, and can reduce the volume of lung that received dose of 10 Gy or higher.
