OBJECTIVE: To compare clinical efficacy of tibial transverse transport (TTT) microcirculation reconstruction and periosteal distraction in treating patients with early diabetic foot(DF). METHODS: From June 2021 to June 2024, 60 patients with DF were admitted and divided into bone transport group and stretch group according to different treatment methods. There were 30 patients in bone transport group, including 16 males and 14 females;aged from 48 to 65 years old with an average of (55.59±3.78) years old;the course of disease ranged from 2 to 9 months with an average of(5.95±1.32) months;TTT microcirculation reconstruction surgery was performed. There were 30 patients in distraction group, including 17 males and 13 females;aged from 47 to 67 years old with an average of (55.24±3.81) years old;the course of disease ranged from 2 to 10 months with an average of (5.68±1.54) months;periosteal distraction surgery was performed. The skin temperature of the affected feet, the time of getting out of bed and walking after operation, the time of full weight-bearing, the wound healing time and complications were compared between two groups;the pain was evaluated by visual analogue scale (VAS) before operation and one month after operation respectively;the changes of blood flow velocity of dorsal foot arteries, ankle brachial index(ABI), epidermal growth factor (EGF), and basic fibroblast growth factor (bFGF) before and after operation at 3 months were compared between two groups. RESULTS: All patients were followed up for 3 to 4 months with an average of (3.52±0.12) months. There were no statistically significant differences in comparison of foot skin temperature, postoperative walking time, full weight-bearing time and complications between two groups (P>0.05). The wound healing time of bone transport group (61.26±7.31) days was shorter than that of distraction group (70.17±7.15) days, and the difference was statistically significant (P<0.05). Postoperative VAS at 1 month of bone transport group (2.19±0.21) was lower than that of distraction group (2.55±0.20), and the difference was statistically significant (P<0.05). At 3 months after operation, the blood flow velocity of dorsal foot artery, ankle-brachial index, EGF and bFGF in bone transport group were(34.73±4.18) cm·s^-1, (0.95±0.13), (716.61±71.13) pg·ml^-1 and (175.69±31.28) pg·ml^-1, respectively;which were higher than that of distraction group (31.86±3.23) cm·s^-1, (0.84±0.11), (677.37±70.21) pg·ml^-1, (149.26±30.13) pg·ml^-1, and the differences were statistically significant (P<0.05). There was no recurrence of ulcers in situ or at other sites in both groups during follow-up. CONCLUSION Compared with periosteal distraction, TTT microcirculation reconstruction surgery has a definite effect in the treatment of early DF. It could effectively reduce pain level, improve blood flow indicators and vascular endothelial function of the foot, and has a relatively high safety.

Objective:To establish autoverification rules for coagulation tests in multicenter cooperative units, in order to reduce workload for manual review of suspected results and shorten turnaround time (TAT) of test reports, while ensure the accuracy of results.Methods:A total of 14 394 blood samples were collected from fourteen hospitals during December 2019 to March 2020. These samples included: Rules Establishment Group 11 230 cases, including 1 182 cases for Delta check rules; Rules Validation Group 3 164 cases, including 487cases for Delta check; Clinical Application Trial Group 77 269 cases. Samples were analyzed for coagulation tests using Sysmex CS series automatic coagulation analyzers, and the clinical information, instrument parameters, test results, clinical diagnosis, medication history of anticoagulant and other relative results such as HCT, TG, TBIL, DBIL were summarized; on the basis of historical data, the 2.5 and 97.5 percentile of all data arranged from low to high were initially accumulated; on the basis of clinical suggestions, critical values and specific drug use as well as relative guidelines, autoverification rules and limits were established.The rules were then input into middleware, in which Stage I/Stage II validation was done. Positive coincidence, negative coincidence, false negative, false positive, autoverification pass rate, passing accuracy (coincidence of autoverification and manual verification) were calculated. Autoverification rules underwent trial application in coagulation results reports.Results:(1) The autoverification algorisms involve 33 rules regarding PT/INR, APTT, FBG, D-dimer, FDP,Delta check, reaction curve and sample abnormalities; (2)Autoverification Establishment Group showed autoverification pass rate was 68.42% (7 684/11 230), the false negative rate was 0%(0/11230), coincidence of autoverification and manual verification was 98.51%(11 063/11 230), in which positive coincidence and negative coincidence were respectively 30.09% (3 379/11 230) and 68.42%(7 684/11 230); Autoverification Validation Group showed autoverification pass rate was 60.37%(1 910/3 164), the false negative rate was 0%(0/11 230), coincidence of autoverification and manual verification was 97.79%(3 094/3 164), in which positive coincidence and negative coincidence were respectively 37.42%(1 184/3 164) and 60.37%(1 910/3 164); (3) Trialed implementation of these autoverification rules on 77 269 coagulation samples showed that the average TAT shortened by 8.5 min-83.1 min.Conclusions:This study established 33 autoverification rules in coagulation tests. Validation showedthese rules could ensure test quality while shortening TAT and lighten manual workload.

OBJECTIVE To investigate the effects of total flavonoids of bugloss(TFB)on left ventricular (LV)remodeling after myocardial infarction(MI),LV size and function was compared in mice subjected to left anterior descending coronary artery ligation. METHODS 28 d after MI, the infarcted fraction of the LV and LV mass, systolic and diastolic function were measured. Capillary density and myocyte width in the nonischemic portion of the LV were also determined.RESULTS 28 d after MI,both groups had dilated LVs with decreased fractional shortening and lower ejection fractions. Although the infarcted size of the LV was similar in both groups,LV end-diastolic internal diameter,end-diastolic volume,and mass were lower, but fractional shortening, ejection fraction, and the maximum rate of developed LV pressure(dp/dtmax)were greater in TFB treated mice than in control mice.Impairment of diastolic func-tion, as measured by the time constant of isovolumic relaxation (t) and the maximum rate of LV pres-sure decay(dp/dtmin),was more marked in control mice than in TFB treated mice.Mortality after MI was greater in control mice than in TFB treated mice.In control mice,capillary density and myocyte width in the nonischemic portion of the LV did not differ before and 28 days after MI, whereas in TFB treated mice, capillary density increased and myocyte width declined after MI. CONCLUSION These results suggest that the presence of TFB limits LV dysfunction and remodeling in a murine model of MI in part by decreasing myocyte hypertrophy in the remote myocardium.

We typed Yersinia pestis isolated from plague foci of Shaanxi Province using different region (DFR) and analyzed epidemiological characteristics.Twenty-three DFRs primers and PMT1 (plasmid) primer were used to verify the DFR genomovars and 48 Yersinia pestis were involved to analyze DFR profiles and epidemiological characteristics.In the same year,the genotypes of Yersinia pestis isolated from different infected vector and animals were basically the same.Three genomovars named Genomovar 11,17,and 20 were verified in 48 Yersinia pestis strains in Shaanxi Province.The main genotypes were different in different epidemic years.In 1987-1988 and 2000-2001 years,genomovar 17 was major genomovar and genomovar 20 in 2006 year.In conclusion,the dominant genotypes were different in different epidemic years.As time goes on,DFR genomovars of Yersinia pestis undergone the evolution of gene deletion,which changes genomovar 17 into genomovar 20.

Objective: To study the safety and efficacy of Bushen Daozhuo Granules (BDG) in the treatment of type Ⅲ prostatitis. METHODS: This multicenter randomized controlled clinical trial included 478 patients with type Ⅲ prostatitis, 290 in the trial group and 188 as controls, the former treated with BDG at 200 ml bid and the latter with tamsulosin hydrochloride sustainedrelease capsules at 0.2 mg qd, both for 4 weeks. Before treatment, after 4 weeks of medication, and at 4 weeks after drug withdrawal, we obtained the NIH Chronic Prostatitis Symptom Index (NIHCPSI) scores and compared the safety and effectiveness rate between the two groups of patients. RESULTS: Compared with the baseline, the NIHCPSI score was markedly decreased in the control group after 4 weeks of medication (21.42 ± 4.02 vs 15.67 ± 3.65, P < 0.05) but showed no statistically significant difference from that at 4 weeks after drug withdrawal (19.03 ± 3.86) (P>0.05), while the NIHCPSI score in the trial group was remarkably lower than the baseline both after 4 weeks of medication and at 4 weeks after drug withdrawal (10.92 ± 2.06 and 12.91 ± 2.64 vs 21.58 ± 3.67, P < 0.05). The trial group exhibited both a higher rate of total effectiveness and safety than the control (P < 0.05). CONCLUSIONS BDG is safe and effective for the treatment of type Ⅲ prostatitis.

Recently, compound Ejiao slurry (FFEJJ) had been applied to treat cancer patients in clinic, with obvious curative effect. In this study, data and literatures were collected from the TCM chemical component database to establish the chemical component database of FFEJJ. Afterwards, MetaDrug software was used to predict the targets of FFEJJ and obtain the compound-target network. Next, the compound-target network was compared and analyzed to obtain the "compound-target-tumor target" heterogeneous network. Besides, further analysis was made on gene functions and metabolic pathway. The results indicated that FFEJJ could directly resist tumors by regulating cancer cell differentiation, growth, proliferation and apoptosis, and show an adjuvant therapeutic effect by enriching the blood and increasing the immunity.

OBJECTIVETo observe the effects of Yangjing Capsule (YJC) on the ultrastructure of seminal vesicles in aged male rats, and explore its mechanism of improving the secretion of seminal vesicles.

METHODSFifty male SD rats aged 18 -20 months were randomly and equally divided into a control group, a testosterone undecanoate group, and a high-dose, a medium-dose and a low-dose YJC group, all fed intragastrically for 30 days. Then the seminal vesicles of the rats were removed and the seminal fluid squeezed into the test tube to be weighed and measured for the concentration of seminal vesicle fluid fructose, and the bilateral seminal vesicles were placed in formaldehyde and glutaraldehyde fixatives for histological observation.

RESULTSThe seminal vesicle gland viscera coefficient, seminal vesicle fluid weight and fructose concentration of the rats were (1164.5 +/- 212.6) g/g x 10(6), (0.83 +/- 0.30) g and (4.35 +/- 0.31) mg/ml in the control group, (1510.5 +/- 313.1) g/g x 10(6), (0.82 +/- 0.25) g and (5.35 +/- 0.71) mg/ml in the testosterone undecanoate group, (1484.3 +/- 262.7) g/g x 10(6), (1.14 +/- 0.18) g and (5.30 +/- 0.45) mg/ml in the high-dose YJC group, (1396.6 +/- 268.9) g/g x 10(6), (0.83 +/- 0.24) g and (4.71 +/- 0.41) mg/ml in the medium-dose YJC group, and (1475.0 +/- 305.2) g/g x 10(6), (0.74 +/- 0.28) g and (4.50 +/- 0.23) mg/ml in the low-dose YJC group. Compared with the control, high-dose YJC significantly improved seminal vesicle secretion (P < 0.05), while medium- and low-dose only achieved a trend of improvement. After HE staining, the YJC groups showed more active epithelial hyperplasia, increased cellular layers, rich and transparent cytoplasm with abundant secretory granules, fat droplets and lipofuscin, blurred glandular cavity edge, and eosinophilic intraluminal secretions, as compared with the control group. The structural change was most significant in the high-dose group. Statistically significant differences were observed in the numerical density and bulk density of the secretory granules between the YJC and control groups (P < 0.05).

CONCLUSIONYangjing Capsule can improve the secretion of seminal vesicles by increasing the secretory granules of the main

OBJECTIVETo observe the effect of Yangjing Capsule on the expressions of P-Erk1 and P-Akt1 in the corpus cavernosum of aged rats and to explore its action mechanism.

METHODSForty 24-month-old SD rats were equally randomized into an experimental and a control group, 10 selected from each group for detection of the eNOS expression before medication. The rats in the experimental group (n = 10) were treated intragastrically with Yangjing Capsule, while those in the control with physiological saline, both at 0.5 g per kg body weight per day for 4 weeks. Then all the rats were killed, and the corpus cavernosum tissues harvested for determination of the expressions of eNOS, P-Erk1 and P-Akt1 by HE staining, RT-PCR and immunohistochemistry.

RESULTSObvious distension was observed in the experimental group, but not in the control. The expression of eNOS in the rat corpus cavernosum was significantly higher after treatment than before treatment in the experimental group (24.10 +/- 2.40 vs 18.80 +/- 2.04, P < 0.05), but presented no obvious difference in the control (18.15 +/- 1.98 vs 19.35 +/- 1.50, P > 0.05), and it was remarkably higher in the former than in the latter (P < 0.05). The expression of P-Erk1 was markedly lower in the experimental than in the control rats (0.71 +/- 0.13 vs 0.83 +/- 0.17, P < 0.01), but that of P-Akt1 exhibited no remarkable difference in the same condition of GAPDH between the two groups (0.58 +/- 0.17 vs 0.48 + 0.13, P > 0.01).

CONCLUSIONBoth P-Erk1 and P-Akt were expressed in the corpus cavernosum of the aged rats. Yangjing Capsule could improve the sexual function of aged rats, which might be associated with the lowered expression of P-Erk1.

OBJECTIVETo evaluate the safety, feasibility, and efficacy of robotic gastrectomy for gastric cancer using da Vinci surgical system.

METHODSA total of 120 patients who underwent robotic gastrectomy using da Vinci surgical system for gastric cancer from May 2010 to April 2012. Data regarding surgical and early oncological outcomes were systematically collected in a specific database for statistical analysis.

RESULTSThere were 74 males and 46 females, with a mean age of 58.5 (22-80) years old. The type of robotic operation included 62 distal subtotal gastrectomies, 35 total gastrectomies, and 23 proximal gastrectomies. Reconstruction of the alimentary tract was achieved using extracorporeal method through a minilaparotomy in 55 cases, and intracorporeal robot-sewn anastomosis in 65 cases. There was 1 conversion (0.9%). The operative time was (245±50) min and the docking time (17±5) min. The blood loss was (70±45) ml. The number of harvested lymph nodes was 22.5±10.7. The resection margins were negative in all surgical specimens. The postoperative pathological stage consisted of stage I B in 24 cases, stage II in 28, stage III A in 47, and stage III B in 21. Six patients (5%) developed postoperative complication including 1 case of duodenal stump leakage, 2 cases of esophagus-gastric leakage, 1 case of small bowel obstruction, 1 case of delayed gastric emptying, and 1 case of abdominal bleeding. All the complications were cured by reoperation or conservative therapy, and there were no postoperative 30-day deaths. The postoperative hospital stay was (6.3±2.6) days.

CONCLUSIONRobotic gastrectomy for the treatment of gastric cancer is a feasible and safe procedure, and is advantageous in terms of lymphadenectomy and alimentary tract reconstruction.
