TCM Stage Differentiation Treatment of Diabetic Gangrene——An Observation on Microcirculatory Changes

Microcirculatory changes and therapeutic effects in 39 non-insulin dependent diabetes mellitus (NIDDM) cases were evaluated. Under the same basic treatment in both groups, the treatment group (21 cases) was treated with TCM drugs according to its stages and compared with the control group (18 cases, treated with 654-2). The results showed that the microcirculatory cumulative scores were significantly decreased in both groups (P<0.05), but the decrease in the treatment group was more marked (P<0.05). In the treatment group, 15 cases were cured, 3 markedly effective, 2 effective and 1 ineffective; while in the control group, 13 cases were cured, 1 markedly effective and 4 ineffective. Statistically, there is no significant difference between the 2 groups (P>0.05) in therapeutic effects.

Usefulness of contrast enhanced ultrasound in monitoring therapeutic response after hepatocellular carcinoma treatment

In the last years, the development in the oncology field has been huge and rapid. In particular, the evaluation of response to anti-tumour treatments has been being object of intense research, producing significant changes. Response assessment after therapy in solid neoplasias has always used radiological imaging techniques, with tumour size reduction representing a presumed therapeutic efficacy. However, with the introduction of anti-angiogenetic drugs the evaluation of tumour size has become unsuitable because some tumours, under treatment, show only tumour perfusion changes rather than lesion shrinkage. Between different imaging techniques with contrast-enhancement, contrastenhanced ultrasound(CEUS) and, in particular, dynamic CEUS have arisen as a promising and non-invasive device for monitoring cancer treatments. Moreover, the introduction of perfusion software has even more refined the technique since it is able to provide quantitative parameters related to blood flow and blood volume that can be associated with tumour response and clinical outcome such as the progression free survival and the overall survival. Here, we give an overview of the current status of CEUS in monitoring hepatocellular carcinoma response to different kind of treatments.

Contrastive Observation of Solar Thermal and Photovoltaic Resource

Solar thermal and photovoltaic applications are the most w idely used and the most successful w ay of commercial development in solar energy applications. Observation and assessment of solar thermal and photovoltaic resources are the basis and key of their large-scale development and utilization. Using the observational data carried out from Beijing southern suburbs observation station of China M eteorological Administration in summer of 2009,preliminary solar thermal and photovoltaic resources characteristics for different w eather conditions,different angle and different directions are analyzed. The results show that:(1) In sunny,cloudy or rainy w eather conditions,both of solar thermal and photovoltaic sensors daily irradiance have consistent change in trend. Solar thermal irradiance is larger than photovoltaic. Under sunny conditions,solar thermal global radiation has about 2.7%higher than the photovoltaic global radiation. Under cloudy w eather conditions,solar thermal global radiation has about 3. 9%higher than the photovoltaic. Under rainy w eather conditions,solar thermal global radiation has about 20% higher than the photovoltaic.(2) For different inclined plane daily global radiation,southern latitude-15 °incline is the maximum and southern vertical surface is the minimum. The order from large to small is southern latitude-15 ° incline,southern latitude incline,southern latitude+15 °incline,horizontal surface and southern vertical surface. Southern latitude-15 °incline global radiation has about 41% higher than the southern vertical surface.(3) For different orientation vertical surface daily global radiation,southern vertical surface is the maximum and w estern vertical surface is the minimum,w hich eastern vertical surface is in the middle. Southern vertical surface global radiation has about 20% higher than the w estern vertical surface.

Prescription of Cancer Treatment Modalities in Developing Countries:Results from a Multi-Centre Observational Study

Background: Treatment is an important component of a comprehensive cancer control approach and its outcomes strongly depend on infrastructure, equipment, human and financial resources available. Therefore it is imperative to generate evidence-based tools to assist health policy makers from low resourced countries in planning efficient and equitable treatment services for a defined population based on what it is feasible to these settings. Methods: The intended cancer spe-cific treatment planned and written in the patients’ medical record (treatment prescription) of untreated adult cancer cases (≥18 years of age), excluding non-melanoma skin cancer, was recorded in a chronological way from 1 January 2012 onwards in a group of eight comprehensive cancer centres located in middle income countries and offering the main modalities of cancer treatment (surgery, medical oncology and radiotherapy). Results: A total of 17,713 medical records were reviewed, of which 7106 (54.2%) met the eligibility criteria. Prescription of main cancer treatment modalities were distributed as follows: 57.6% for chemotherapy (n = 4093), 56.8% for surgery (n = 4038), and 46.8% for radiotherapy (n = 3327). There was a predominance of plans consisting of combined treatment modalities over monotherapy (55.2% versus 44.8%). At the time of diagnosis 54.3% of the cancer cases had disease that had spread beyond the primary site, 41.2% were considered as having local disease and in 4.5% of the cases the information on disease extension was unknown. Conclusions: The results obtained should be seen as an approximation of cancer treatment service demand based on what it is currently practiced and therefore feasible in developing countries, particularly in middle income countries.

Effects of Steam Heat Treatment on the Surface Contact Angle of Chinese Fir

The aim of this study was investigate the effects of heat treatment on the contact angle of Chinese fir, and the indicators affecting the change of contact an-gle change. It was determined that the duration of treatment had significant effect on the change curves of contact angle of Chinese fir wood due to the change curves of contact angle became more centralized and orderly after the specimens heat treated at 180 ℃. Compared with the untreated wood, the contact angle in-creased from 51＆#176; to 124＆#176; after 4 h treatment, and hydroxyl absorbance of hy-drophilic functional groups decreased from 2.08 to 1.63, while carbonyl absorbance from 0.92 to 0.62. The surface roughness has not significant influence on the con-tact angle. Heat treatment of the Chinese fir caused surface morphological change, which produced hol owed-out phenomenon. The increased surface contact angle caused by heat treatment can be used for outdoor and sauna facilities.

“Wait and scan” management of patients with vestibular schwannoma and the relevance of non-contrast MRI in the follow-up

Vestibular schwannoma(VS) is a slow-growing benign neoplasm. There has been an evolution in the management of VS from active treatments(microsurgery and stereotactic radiotherapy) to conservative management(wait and scan). Regular MRI scanning is necessary to monitor tumor progression. Conservative management causes significantly less complications and offers a higher quality of life compared with active treatments. The mean growth rate of VS varies from 0.4 to 2.9 mm/year, and spontaneous shrinkage is observed in 3.8 percent of tumors during observation. If significant growth occurs, active treatment is considered. Significant growth is defined as an increase of at least 3 mm in the largest extrameatal diameter in any plane between the first and last available scans. The vestibulocochlear nerve is surrounded by cerebrospinal fluid, which provides natural contrast for MRI; thus, gadolinium may not be needed to detect VS. Specific sequences have high sensitivity, specificity, and accuracy for detection of progression. Hypointense signal in the ipsilateral inner ear fluid might be a useful sign to distinguish VS from meningioma. In this paper, we summarize the current status of research on conservative management and non-contrast MRI for the detection of VS.

A modified active disturbance rejection control for a wastewater treatment process

Waste water treatment process(WWTP)control has been attracting more and more attention.However,various undesired factors,such as disturbance,uncertainties,and strong nonlinear couplings,propose big challenges to the control of a WWTP.In order to improve the control performance of the closed-loop system and guarantee the discharge requirements of the effluent quality,rather than take the model dependent control approaches,an active disturbance rejection control(ADRC)is utilized.Based on the control signal and system output,a phase optimized ADRC(POADRC)is designed to control the dissolved oxygen and nitrate concentration in a WWTP.The phase advantage of the phase optimized extended state observer(POESO),convergence of the POESO,and stability of the closed-loop system are analyzed from the theoretical point of view.Finally,a commonly accepted benchmark simulation model no.1.(BSM1)is utilized to test the POESO and POADRC.Linear active disturbance rejection control(LADRC)and the suggested proportion-integration(PI)control are taken to make a comparative research.Both system responses and performance index values confirm the advantage of the POADRC over the LADRC and the suggested PI control.Numerical results show that,as a result of the leading phase of the total disturbance estimation,the POESO based POADRC is an effective and promising way to control the dissolved oxygen and nitrate concentration so as to ensure the effluent quality of a WWTP.

Unilateral contrast-induced encephalopathy with contrast medium exudation:A case report

BACKGROUND Contrast-induced encephalopathy(CIE)is a rare transient,reversible abnormality in the structure or function of the nervous system caused by the intravascular use of contrast agents.CIE can present with a range of neurological manifestations,including focal neurological deficits(hemiplegia,hemianopia,cortical blindness,aphasia,and parkinsonism)and systemic symptoms(confusion,seizures,and coma).However,if not accurately diagnosed and treated in a timely manner,CIE can cause irreversible damage to patients,especially critically ill patients.CASE SUMMARY A male in his 50 s,2 h after digital subtraction angiography,had a progressive disorder of consciousness,mixed aphasia,bilateral pupillary sluggish light reflex,and right limb weakness.Seven hours after the procedure,he developed unconsciousness,high fever(39.5°C),seizures,hemiplegia,neck stiffness(+),and right Babinski signs(+).computed tomography(CT)findings 2 h postprocedure were very confusing and led us to misdiagnose the patient with subarachnoid hemorrhage.Brain CT was performed again 7 h after the procedure.Compared with the CT 2 h after the procedure,the CT 7 h after the procedure showed that the manifestations of subarachnoid hemorrhage in the left cerebral hemisphere had disappeared and were replaced by brain tissue swelling,and the cerebral sulci had disappeared.Combined with the clinical manifestations of the patient and after the exclusion of subarachnoid hemorrhage and cerebrovascular embolism,we diagnosed the patient with CIE,and intravenous fluids were given for adequate hydration,as well as mannitol,albumin dehydration,furosemide and the glucocorticoid methylprednisolone.After 17 d of active treatment,the patient was discharged with no sequelae.CONCLUSION CIE should be taken seriously,but it is easily misdiagnosed,and once CIE is diagnosed,rapid,accurate diagnosis and treatment are critical steps.Whether a follow-up examination using a contrast agent can be performed should be closely evaluated,and the patient should be fully informed of the associated risks.
