Objective To observe the clinical efficacy of ginger-partitioned moxibustion in improving blood flow velocity in lower limbs of post-stroke patients.Methods Ninety post-stroke patients were randomized into a treatment group and a control group, 45 in each group. The treatment group was intervened by ginger-partitioned moxibustion, while the control group was by conventional acupuncture. Before and after intervention, the blood flow velocity in lower limbs, National Institute of Health Stroke Scale (NIHSS) and modified Barthel Index (MBI) were evaluated.Results After 4-week treatment, the maximum blood flow velocity (Vmax) was significantly changed in the treatment group (P<0.05), and there was a significant difference in comparing the Vmax between the two groups after intervention (P<0.05); the NIHSS and MBI scores were significantly changed after intervention in the treatment group (P<0.05), and there was a significant difference in comparing MBI score between the two groups after intervention (P<0.05).Conclusions Ginger-partitioned moxibustion can accelerate the blood flow velocity in lower limbs of the post-stroke patients, improve blood circulation and the activities of life.

OBJECTIVEThis longitudinal study aimed to investigate the caries status of primary and permanent teeth among 6-year-old children in Sichuan Province from 2010 to 2012.

METHODSA sample that comprised 652 6-year-old children from six different elementary schools (three represented the urban areas, and the other three represented the rural areas) were examined according to a baseline, with follow-up examinations at 1, 2, and 3 years. Eruption and caries experience were re- corded using World Health Organization criteria.

RESULTSThe prevalence rates of primary tooth caries of 6-year-old children in Sichuan Province for 3 years were 74.23% (484/652), 75.61% (493/652), and 81.90% (534/652). The filling rate of the primary teeth was 5.87% (145/2,471) in 2012, with significant differences (P < 0.01) between the urban areas [10.84% (133/ 1,227)] and rural areas [0.96% (12/1,244)]. The total pit and fissure rate of the first molar was 14.11% (92/652) in 2012, with significant differences between the two areas (P < 0.01) [rural: 0.66% (2/303); urban: 25.79% (90/349)].

CONCLUSIONThe pre- valence of caries in the primary and permanent teeth of 6-year-old children was high. An increasing prevalence tendency was observed as the age increased. The prevalence of first molar caries indicated that prevention and control of dental caries should be performed as early as possible.

Objective To investigate the related risk factors,clinical features and prognosis of hospital-acquired acute kidney injury (AKI) in intensive care unit (ICU).Methods We retrospectively analyzed 48 patients with both acute kidney injury and multiple organ dysfunction syndrome (MODS),who received renal replacement therapy from October 2006 to February 2011 in our ICU.According to whether the occurrence time of AKI was 48 hours after admission,they were divided into hospital-acquired AKI (HA-AKI) group and community-acquired AKI (CA-AKI) group,with 13 and 35 cases respectively.We compared the differences between these two groups in gender,age,acute physiology and chronic health evaluation Ⅲ (APACHE Ⅲ),primary diseases,days of mechanical ventilation,times of renal replacement therapy,number and indicators of organ failure,prognosis,renal function recovery,length of stay in ICU and hospital.Results The mean age of HA-AKI group is ( 64.5 ± 21.4) years,which is older than that in CA-AKI group ( 50.2 ± 17.5 ) years (P=0.022).The top three primary diseases in CA-AKI group are severe infection(42.8％ ),chronic kidney disease (CKD) concurrency of AKI ( 11.4％ ) and multiple trauma without head injury ( 8.6％ ).However severe infection still occupies the first in HA-AKI group ( 30.8％ ),followed by stroke (23.1％,P=0.024),multiple trauma with head injury( 15.4％,P=0.018 ) and gastrointestinal bleeding( 15.4％ ) ;Patients in HA-AKI group with more than four organ failures account for 84.6％,significantly higher than 65.7％ in CA-AKI group (P=0.000).On the first day,the levels of serum sodium ( P =0.036 ) and bicarbonate ( P=0.001 ) in HA-AKI group are higher than that in CA-AKI group,and the urinary volume is more(P =0.046).In HA-AKI group,the level of urea nitrogen on the seven day increases so progressively that it becomes significantly higher than that on the first day(P=0.015),but in CA-AKI group,there is no significant change in the levels of serum creatinine and urea nitrogen after AKI,while the levels of seruum sodium ( P=0.023 ) and bicarbonate ( P=0.030) increase significantly;APACHE Ⅲ score in HA-AKI group after admission 24 hours is significandy lower than that in CA-AKI group(53.2 ±22.8) point vs (89.1±25.7) point,P=0.000),and the length of stay in ICU and hospital and days of mechanical ventilation in HA-AKI group are significantly longer than that in CA-AKI group,but there are no significant differences in times of RRT therapy,prognosis and recovery of renal function.Conclusion APACHE Ⅲ score after 24 hours of admission does not accurately reflect the prognosis of patients with MODS and HA-AKI.There are great differences in age,primary diseases,organ function changes and other aspects of HA-AKI when compared with CA-AKI.

Radiopharmaceutical is an essential component of nuclear medicine and molecular imaging, as well as a key component of precision medicine. The United States Food and Drug Administration (FDA) has recently approved the marketing of several peptide-based radiopharmaceuticals, sparking a global trend of research in this area and propelling nuclear medicine into the precision theranostic era. This has created a new wave of technological competition in the field of nuclear medicine. It is the responsibility of Chinese scientists in the radiopharmaceutical field to capitalize on this opportunity, leverage the momentum, and strengthen their independent innovation capability in order to stay ahead in the future global nuclear science and technology competition. This review provides an overview of the remarkable progress made in the research, development, and translation of global peptide-based radiopharmaceuticals. It examines the advantages of peptide-based radiopharmaceuticals and outlines the current hot targets and progress in drug development in this field. Additionally, it proposes six opportunities for China to overtake others in the field of peptide-based radiopharmaceuticals and achieve technological self-reliance, based on interdisciplinary collaboration and independent innovation. Lastly, the future prospect of peptide-based radiopharmaceuticals is discussed.

Objective: To investigate the effect of adiponectin levels with its related mechanism in diabetic myocardial ischemia-reperfusion injury and ischemia post-conditioning in experimental rats. Methods: A total of 80 male SD rats were randomly divided into 6 groups: Normal sham (NS) group,n=8, Normal ischemia-reperfusion injury (NIRI) group,n=16, Normal ischemia post-conditioning (NIPO) group,n=16 and Diabetic mellitus sham (DMS) group,n=8, Diabetic mellitus ischemia-reperfusion injury (DMIRI) group,n=16, Diabetic mellitus ischemic post-conditioning (DMIPO) group,n=16. DM rats model was established by intraperitoneal injection of streptozotocin; IR model was established by occlusion of left anterior descending (LAD) coronary artery for 30 min followed by reperfusion for 120min; IPO model was established by 3 cycles of ischemia for 10s and reperfusion for10s; the rats in Sham group received silk line wrapping of LAD without occlusion. The myocardial infarction (MI) area was measured by TTC staining, plasma adiponectin level was examined by ELISA, the protein expressions of p-Akt and total-Akt were detected by Western blot analysis. Results: Compared with NIRI group, NIPO group had decreased MI area,P<0.05, while DMIRI group and DMIPO group had increased MI area,P<0.01; compared with NS group, NIRI group and NIPO group showed up-regulated expression of adiponectin and p-Akt,P<0.05 and DMS group showed down-regulated p-Akt,P<0.05. Compared with NIPO group, three DM groups presented down-regulated adiponectin and p-Akt,P<0.05. Linear correlation analysis indicated that plasma adiponectin expression level was negatively related to MI area and positively related to myocardial tissue p-Akt expression with the correlation coefifcient at 0.63 and 0.65 respectively, P<0.01. Conclusion: Down-regulated plasma adiponectin expression may cause the inactivation of PI3K/Akt signal pathway and therefore aggravate DM ischemia-reperfusion injury which cannot be protected by ischemic post-conditioning in experimental rats.

Re-evaluation of bioequivalence of generic drugs is one of the key research focus currently. As a means to ensure consistency of the therapeutic effectiveness of drug products, clinical bioequivalence has been widely accepted as a gold standard test. In vitro dissolution testing based on the theory of the BCS is the best alternative to in vivo bioequivalence study. In this article, the conventional dissolution method and flow-through cell method were used to investigate the dissolution profiles of domestic amoxicillin capsules in different dissolution media, and the absorption behavior of the drugs with different release rates (t85% = 15-180 min) in the gastrointestinal tract was predicted by Gastro Plus. The flow-through cell method was thought better to reflect the release characteristics in vivo, and amoxicillin capsules with regard to the release rates up to 45 min (t85% = 45 min) were having a satisfied bioequivalence with the oral solution according to the C(max) and AUC. Although two different dissolution profiles of domestic amoxicillin capsules were found by flow-through cell methods, prediction results revealed that domestic capsules were probably bioequivalent to each other.

ObjectiveTo investigate the effect of vacuum sealing drainage (VSD) with different negative pressures on variation of oxygen partial pressure (PtO2 ) and wound healing in the rabbits.MethodsTwelve rabbit wound models were made and randomly (random number) divided into two groups, namely vacuum group ( n =6 )in which rabbits were treated with VSD by different negative pressures ( - 75 mmHg,- 125 mmHg,- 225 mmHg and - 350 mmHg) for 7 days, and routine treatment group ( n =6). At each interval of measurement, variation of PtO2 was measured by oxygen partial pressure admeasuring device, and area of VSD dressing and surface of wound were measured by vernier caliper, and growth of anaerobic bacteria was detected by bacterial culture, and morphological change and the course of wound healing were observed under by light microscope after HE tissue staining. Meanwhile anther two groups (n =6, in each) were set for comparing, including normal group, sham operation group. ResultsAverage PtO2 value of vacuum group was in the range of ( 1.87 +0. 19) kPa to ( 1.54 ±0. 21 ) kPa which was decreased gradually in 7 days under different negative pressures. Average PtO2 value of routine treatment group and normal group were ( 2. 82 ± 0. 37 ) kPa and ( 5.79 + 0. 50 ) kPa, respectively which weresignificant higher than that in vacuum group ( P ＜ 0. 01 ). PtO2 was fell to 80. 94％ of its original value after VSD for 5 seconds, and continued the downward trend with the increasing of negative pressure at the same interval of measuring. Area of VSD dressing significantly decreased to 65. 36％ of its original area after VDS for5 minutes (P＜0.01). Surface of wound was minimized to 62. 82％ of its original area after VSD for 7 days ( P ＜ 0. 01 ), and variations of those in - 350 mmHg group were significant greater than those in other groups ( P ＜ 0. 01 ). There was no evidence of anaerobic bacteria growth in vacuum group during this experiment. ConclusionsPtO2 could be down-regulated by VSD significantly without growth of anaerobic bacteria, and minimization of VSD dressing at - 350 mmHg was significantly helpful to reduce the area of wound for promoting the healing.

The institutional cooperation between military and civilian hospitals was also based on the principle of proximity of locations and similiarity of research.Cooperation between productive authors mainly occurred in the same research group but co-au-thorship outside the research group was scarce.The potential competition or cooperation between research fields and authors can be analyzed by comparing co-authorship and author-keyword co-occurrence.

AIM: To investigate the visual recovery and complications in patients with traumatic cataract treated by intraocular lens Ⅰ phase implantation and Ⅱ phase implantation.?METHODS: Totally 86 patients with traumatic cataract (86 eyes) treated in our hospital from January 2014 to December 2016 were enrolled in the retrospective study, and they were divided into the control group ( treated by intraocular lens Ⅰ phase implantation, 46 eyes) and the observation group ( treated by intraocular lens Ⅱ phase implantation, 40 eyes). The general situation of surgery, the visual recovery at 6mo after operation and the incidence rate of complications in two groups were observed.?RESULTS: There were no significant differences in surgical time, intraoperative blood loss and hospitalization time between the two groups (P>0. 05). There was no significant difference in the excellent and good rate of visual acuity between the two groups before operation between the twogroups (P>0. 05). At 6mo after operation, the excellent and good rates of visual acuity in two groups obviously increased ( P<0. 05 ), while there was no significant difference in the excellent and good rates of visual acuity at 6mo after operation between the two groups ( P > 0. 05 ). There was no significant difference between the two groups in the incidence rates of posterior capsule rupture and vitreous body prolapse (P>0. 05). The incidence rates of corneal edema, iridocyclitis and posterior capsular opacification in the observation group after operation were significantly lower than those in control group (P<0. 05).?CONCLUSION:The effects of IOLⅠphase implantation and Ⅱ phase implantation are similar in patients with traumatic cataract, in terms of the general situation and improvement of visual recovery. However, the incidence of complications after Ⅱ phase implantation is relatively lower.
