Objective To investigate the association of serum C peptide concentration with the severity and the outcome of diabetic foot ulcer (DFU). Methods The clinical data of 257 inpatients with DFU were collected, including fasting and postprandial 2h C peptide levels and C peptide area under curve (AUCCP ). The patients were followed up on the outcomes of ulcers and death. The associations of serum C peptide concentration with the Wagner degree, infection severity, and healing rate were analyzed. Results The medians of fasting and 2h postprandial serum C peptide as well as AUCCP were 1. 37(0. 02 ~ 9. 00) nmol/ L, 3. 22(0. 02 ~ 29. 61) nmol/ L, and 511. 65 (3. 60 ~ 2 691. 30)nmol·min-1 ·L-1 respectively, which were lower than general levels. The time of follow-up in our study was 2. 8 (1. 0 ~ 5. 1) years. By the end of study, the wound of 75. 88% patients was healed, 3. 5%undergone major amputation, and 23. 74% died. After adjusting for relative factors, there were no significant associations of serum fasting and postprandial C peptide levels and AUCCP with Wagner degree and infection severity (P>0. 05). Cox regression analysis showed that the fasting plasma C peptide and hemoglobin were the independent protective factors for the healing of ulcers; old age, male, higher infection degree, and diabetes family history were their independent risk factors ( all P < 0. 05). Conclusions The lower plasma fasting C peptide concentration in patients with DFU is not correlated with Wagner degree and infection severity, but closely related with healing rate.

RNA interference(RNAi)is a process by which introduced small interfering RNA(siRNA)can cause the specific degradation of mRNA with identical sequences. The human herpes simplex virus type 1(HSV-1)RR is composed of two distinct homodimeric subunits encoded by UL39 and UL40, respectively. In this study, we applied siRNAs targeting the UL39 and UL40 genes of HSV-1. We showed that synthetic siRNA silenced effectively and specifically UL39 and UL40 mRNA expression and inhibited HSV-1 replication. Our work offers new possibilities for RNAi as a genetic tool for inhibition of HSV-1 replication.

OBJECTIVETo evaluate the clinical value of domestically manufactured digital colposcope system (SLC-2000) in the detection of early cervical lesions.
METHODSDuring a follow-up study of patients in Xiangyuan county, Shanxi, a high risk area for cervical cancer, a digital colposcope and an optical colposcope were randomly used for diagnosis, with pathology as the gold standard.
RESULTSIn 163 cervical biopsy specimens, 103 were diagnosed as chronic inflammation by histologic examination. Among 60 specimens which gave abnormal pathology, there were papilloma 1, cervical intra-epithelial neoplasia (CIN) I 37, CIN II 18 and CIN III 4. In 33 endocervical curettage specimens, 3 were pathologically positive. Comparing the digital and optical colposcope in diagnosing the positive lesions of > or = CIN I, the sensitivity of the former and latter were 83.3% and 95.0%, the difference without being statistically significant (P = 0.075). The specificity, positive predictive value, and accuracy of these two instruments were 61.2%, 21.4%, 55.6% and 41.3%, 69.3% 48.5%, with significant difference (P = 0.000, P = 0.035, and P = 0.000). In diagnosing > or = CIN II cervical lesions, these three results of the two instruments did not show any significant difference either. The negative predictive value of the digital and optical colposcope were 86.3% and 88.0%, also showing no significant difference (P = 0.075).
CONCLUSIONThe specificity, positive predictive value, and accuracy of the digital colposcope in diagnosing cervical lesions > or = CIN I are all superior to those of the traditional optical colposcope, even though the sensitivity of the latter is higher. There is no difference between the two instruments in diagnosing lesions > or = CIN II. Not only is domestic digital colposcope (SLC-2000) effective, but feasible and practical in the diagnosis, research and follow-up of cervical lesions.

Objective Secondary infection with pseudomonas aeruginosa( PA) in diabetic foot ulcer( DFU) was analyzed to investigate the related risk factor, antibiotic resistance, and prognoses of the infection. Methods Pathogen cultures were carried out in 966 DFU patients with their clinical data collected. All of the patients were followed-up for two years to observe the outcomes, including ulcer healing, amputation, recurrence of ulcers, non-fatal cardiovascular events, and death. The antibiotic susceptibility, risk factors and associated outcome of secondary PA infection were analyzed. Results Total incidence of PA infection was 13. 0% in DFU patients, of which 38. 1%was secondary. The susceptibility rates of secondary infected PA to tobramycin, meropenem, eftazidime, levofloxacin, cefepime, and cefepime were similar to those in primary infected PA. However, the susceptibility rates of secondary infected PA to piperacillin, piperacillin/tazobactam, ciprofloxacin, imipenen, gentamicin, aztreonam, and amikacin decreased by 12% to 22% as compared with primary infected PA. The healing rate was much lower in patients with secondary PA infection compared with those with primary PA infection, and the accumulated healing rates at2yearswere44.44% and70.4% (P=0.01) respectively. Theriskofulcerhealingfailurewithintwoyears increased by 3 folds in patients with secondary PA infection. After adjusting for age, sex, Wagner grade, infection grade, and duration of DFU, plasma albumin level was an independent risk factor for secondary PA infection in patients with DFU(P=0. 001). Conclusions The antibiotics susceptibility rates of secondary infected PA were lower than those of primary infected PA. Secondary PA infection in DFU was less likely to be healed. Plasma albumin level was a risk factor for secondary PA infection.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.
