Objective To evaluate the availability and sensitivity of MR whole body diffusion weighted imaging (DWI) in searching primary tumors in patients with metastases.Methods Thirty-four patients with symptoms of metastases and unknown primary leasions were scanned by whole body DWI.All the metastases cases were diagnosed by CT,single photon emission computed tomography(SPECT) or MRL For the cases of suspected primary tumors,apparent diffusion coefficient (ADC) values of the primary and metastatic lesions were measured respectively.For the cases with primary lung cancers and metastases proved by pathology of biopsy or surgical specimens,statistics analysis of ADC values of primary and metastatic lesions was performed with paired samples t-test.The detection rate and sensitivity of this technique for screening primary tumors were evaluated.Results By whole body DWI,24 cases were found with suspected primary lesions,in which 23 cases were proved primary tumors,and 1 case was proved benign lesion.Ten cases were not identified with primary lesions on whole body DWI,but in which 2 cases were proved primary malignant tumor by biopsy later,and the other 8 cases remained unknown within follow-up of half a year to one year.For the 14 definite cases of lung cancers,the average ADC values of primary and metastatic lesions was (1.24±0.18)×10-3 and(1.16±0.27)×10-3mm2/s,respectively (t=1.28,P>0.05).The detection rate and sensitivity of whole body DWI for searching primary tumors was 67.6% (23/34) and 92.0% (23/25),respectively.Conclusion The sensitivity of whole body DWI for searching primary tumors is relatively high,and it can be used to search primary tumors in patients with metastases.

Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for dysmenorrhea due to deficiency cold. Methods: A total of 70 patients with dysmenorrhea who met the inclusion criteria were randomized into a mild moxibustion group and a herbal cake-partitioned moxibustion group by the random number table, with 35 cases in each group. Shenque (CV 8), Zhongji (CV 3) and bilateral Zigong (EX-CA 1) were selected for both groups. The treatment continued for 3 menstrual cycles. The visual analog scale (VAS) and COX menstrual symptom scale (CMSS) were scored in both groups before treatment, after treatment and at the end of the 3rd menstrual cycle after treatment. The clinical efficacy was evaluated at the end of the 3rd menstrual cycle after treatment. Results: After treatment, the clinical efficacy of the herbal cake-partitioned moxibustion group had the tendency to be superior to that of the mild moxibustion group, while there was no statistically significant difference in the overall efficacy between the two groups (P>0.05). The VAS and CMSS scores after treatment and at the follow-up were significantly lower than those before treatment in both groups (all P<0.05). At the follow-up, the VAS scores in both groups had no significant intra-group differences from those after treatment (both P>0.05). The CMSS scores in both groups were significantly lower than those after treatment (both P<0.05). The VAS scores at the follow-up of both groups had no statistical differences from those after treatment (both P>0.05). After treatment, the CMSS score in the herbal cake-partitioned moxibustion group was significantly lower than that in the mild moxibustion group (P<0.05). At the follow-up, there were no statistical differences in the CMSS score between the two groups (P>0.05). Conclusion: The herbal cake-partitioned moxibustion has the same therapeutic efficacy for dysmenorrhea as the mild moxibustion; the two moxibustion methods can significantly improve the concomitant symptoms of dysmenorrhea, and the herbal cake-partitioned moxibustion is little better.

Vascular endothelium plays an important role in regulating vascular homeostasis. Over the past years, it has become clear that endothelial dysfunction is a key event of pathophysiological changes in the initiation and progression of injuries induced by extreme environmental factors. The present review summarizes current understanding of vascular endothelial dysfunction induced by hypoxia, cold and heat, and provides the information for prevention and treatment of environmental exposure injuries.

The dissolution of substrate is the key step in steroid microbial conversion.The formation of surfactant micelle with a hydrophobic center directly results in increased pseudo-water-solubilities of hydrophobic compounds such as steroids.Results showed increased water solubility of steroid with the increased surfactant concentrations.Compared to mono-surfactant PSE,less quantity of multiple surfactants PSE-MGE was required to achieve the enhancement of steroid solubility at the same level,thus the negative effects of surfactants on mycelial growth were reduced and steroid conversion was therefore improved more.It was also shown that the surfactants and ultrasonic irradiation used jointly could result in better substrate dispersion and dissolution than surfactants used alone,and the best result was obtained when the comparatively high intensity (12.4 W/cm 2) and short time (5min) of ultrasonic irradiation were performed.

Intensifying the continuing education of doctors in hospitals at primary level is one of the important measures for increasing their specialized skills and improving the condition of primary care.In recent years,following the trend of national medical reform,the Fourth Military Medical University (FMMU) has made full use of its advantages to provide training for civilian doctors in hospitals at primary level.In the training,with the reform measures of ‘ four focuses' and ‘ five combinations',FMMU actively advanced teaching reform to make innovations in curriculum system and teaching methods,which was approved by teachers and students.These measures were very effective,which in turn greatly enhanced the ability of the doctors and training quality.This practice obviously pushed forward development of primary-level medical and health-care service in Shanxi province.

The clinical characteristics of patients who presented in poor clinical grade due to ruptured middle cerebral artery aneurysms (MCAAs) associated with large sylvian hematomas (SylH) were analyzed and an ingenious designed prophylactic hinged craniectomy was introduced. Twenty-eight patients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries (aneurysm clipping, hematoma evacuation and prophylactic hinged craniectomy) were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable outcomes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients' anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding (P<0.05). There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups (P>0.05). However, ingenious designed prophylactic hinged craniectomy efficiently reduced the patients' intracranial pressure (ICP) after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis of MCAA patients presenting with large SylH.

Objective: To observe the clinical efficacy of DZWJY-1 type electronic moxibustion apparatus and traditional moxibustion in treating knee osteoarthritis (KOA). Methods: A total of 76 eligible patients were randomized into an electronic moxibustion apparatus group and a traditional moxibustion group, with 38 cases in each group. The electronic moxibustion apparatus group was intervened by DZWJY-1 type electronic moxibustion apparatus, and the traditional moxibustion group received moxa stick moxibustion for treatment. Neixiyan (EX-LE 4), Dubi (ST 35), Xuehai (SP 10) and Liangqiu (ST 34) were selected for both groups and the treatment was conducted 3 times a week for a total of 12 times. The visual analog scale (VAS) and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) scores were observed before treatment and after 6 and 12 sessions of treatment, respectively. Results: There were 4 dropout cases in the traditional moxibustion group. Therefore, this trial had 72 valid cases, including 38 cases in the electronic moxibustion apparatus group and 34 cases in the traditional moxibustion group, the differences in the baseline data between the two groups were statistically insignificant (P>0.05). After 6 and 12 sessions of treatment, the VAS scores decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the betweengroup differences were statistically insignificant at the same time points (both P>0.05). The pain intensity was evaluated using the weighted value of VAS score. The markedly effective rate was 47.4％ and the total effective rate was 89.5％ in the electronic moxibustion apparatus group, versus 50.0％ and 94.1％ in the traditional moxibustion group, and the betweengroup differences were statistically insignificant (both P>0.05). After 6 and 12 sessions of treatment, the total score and the component scores including pain, stiffness and difficulty moving in the WOMAC decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the between-group differences were statistically insignificant (all P>0.05). Conclusion: Electronic moxibustion apparatus and traditional moxibustion both are effective in reducing joint pain and improving joint function in KOA patients, and they are equivalent comparing the clinical efficacy.

Objective To evaluate the clinical efficacy of electronic mild moxibustion equipment in treating knee osteoarthritis (KOA) by using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Method Sixty-six eligible patients were randomized into a mild moxibustion equipment group of 33 cases and a moxibustion group of 33 cases. The mild moxibustion equipment group was intervened by electronic mild moxibustion equipment, and the moxibustion group was treated with moxibustion. In the two groups, same acupoints were selected, including Neixiyan (EX-LE4), Dubi (ST35), Xuehai (SP10) and Liangqiu (ST34), and the treatment lasted for 4 weeks. The WOMAC scores of the two groups were observed before and after the treatment.Result The WOMAC scores dropped significantly in both groups after the intervention (P<0.001), and the score of the mild moxibustion equipment group was significantly lower than that of the moxibustion group (P<0.05).Conclusion Electronic mild moxibustion equipment and moxibustion both can effectively mitigate joint pain and improve knee joint function, but the moxibustion equipment can produce a more significant effect in improving the joint function than moxibustion.
