OBJECTIVETo observe the effect of Ningzhi Capsule (NZC) on blood lipid spectrum in type 2 diabetes mellitus patients complicated with hyperlipemia (DM-HL).

METHODSAdopting randomized, parallel and controlled trail method, a total of 70 DM-HL patients of qi-yin deficiency and phlegm-blood stagnant syndrome type were randomized into two groups. The original medication for lowering blood sugar and blood pressure was unchanged, the trial group received oral administration of NZC 5 tablets, 3 times a day, while the control group received Lipanthgl or Simvastatin depending on their different constituents of blood lipids. After 6 months of treatment, sixty subjects completed the trail while two patients dropped out due to side effect and 8 patients lost follow-up (4 in each group). Levels of blood lipids, blood routine, liver and kidney function and symptoms in patients were detected and compared.

RESULTSAfter treatment, levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), apoprotein B, and lipoprotein a (LPa) lowered, while levels of high-density lipoprotein (HDL-C) and apoprotein A raised in the trial group as compared with those before treatment (P < 0.05, P < 0.01), but showed no difference between the two groups after treatment except HDL level (P > 0.05). Scores of symptoms were also lowered significantly in the trial group (P < 0.01). In the observation period, no abnormal findings in blood and urine routine examination as well as in liver and renal function were found.

CONCLUSIONNZC could lower the blood lipid spectrum and improve the TCM symptoms in DM-HL patients without any adverse reaction.

This article reviews the clinical and experimental researches on cognitive impairment related to diabetes in the recent decade. Most clinical studies indicate that the cognitive impairment in patients with type 1 diabetes mellitus is related to recurrent hypoglycemia closely. There is little research about whether or not hyperglycemia is related to cognitive impairment in patients with type 1 diabetes mellitus. Most studies indicate that the cognitive impairment in type 2 diabetes involves multiple factors through multiple mechanisms, including blood glucose, blood lipid, blood pressure, level of insulin, medication, chronic complication, etc. But, there has been no large-scale, multi-center, randomized controlled clinical trial in China recently. And what is more, some problems exist in this field of research, such as the lack of golden criterion of cognitive function measurement, different population of studied objects, and incomprehensive handling of confounding factors. Experimental studies found that hippocampal long-term potentiation (LTP) was impaired, which were manifested by impairment of spatial memory and decreased expression of LTP, but it's relation to hyperglycemia, the duration of diabetes, learning and memory has always been differently reported by different researches. Thus, there are a lot of unknown things to be explored and studied in order to clarify its mechanism. TCM has abundant clinical experience in treating cerebral disease with medicine that enforces the kidney and promotes wit. However, there has been no research on treating diabetic cognitive impairment, which requires work to be done actively and TCM to be put into full play, in order to improve the treatment of diabetes and enhance living quality of patients.

OBJECTIVETo improve the X-ray diagnosis of cervical spondylosis of vertebral artery type (VCS).

METHODSA blinded design research. The X-ray signs both 60 patients with VCS and 60 patients with cervical spondylotic radiculopathy were collected from January 2011 to November 2012. There were 36 males and 84 females, aged from 25 to 65 years old with an average of (48.4 ± 12.3) years old. Cervical curvature, atlanto-occipital joint angle, atlanto-axial joint angle, C2/C3 joint angle and lower cervical instability condition and segmental distribution were measured and recorded by X-rays. These data were analyzed and compared between the two groups after unblended. Combined with clinical manifestations,the X-ray imaging features of VCS were further analyzed.

RESULTSThere was significant difference in cervical curvature between two groups in anteflexion X-ray films (P < 0.05). There was significant difference in extension degree of atlanto-occipital joint angle between two groups (P < 0.01). There was significant difference in atlanto-axial joint angle between two groups in lateral X-ray films (P< 0.05). There was significant.difference in anteflexion degree of atlanto-axial joint angle between two groups (P < 0.05). There was no significant difference in C2/C3 joint angle between two groups. There was no significant difference in the lower cervical instability condition and segmental distribution between two groups. In VCS group, the mild and moderate dizziness was main symptom, flexion and extension activities of neck was most common cause in the dizziness; and always accompanied with headache; tenderness mostly concentrated in the upper cervical area.

CONCLUSIONBoth X-ray signs and clinical manifestations can prompt the abnormalities of the upper cervical structure or function in patients with VCS. Anteflexion activities of neck observed by functional position of X-ray films should be emphasized in diagnosis of VCS.

OBJECTIVETo investigate the effect of Wenjingtong Composita (WJTC) on blood glucose and advanced glycosylation end products (AGEs) in sciatic nerve of streptozotocin (STZ)-induced diabetic rats.

METHODSSTZ-induced diabetic rats were randomized to WJTC prevention group and WJTC treatment group. The levels of blood glucose and AGEs in sciatic nerve of the animals were checked after 12 weeks treatment and compared with that of aminoguanidine (AG) treatment group.

RESULTSBlood glucose level in the WJTC prevention and treatment group, and AGEs in sciatic nerve of the WJTC prevention group and the AG group were lower than those of the non-treated group (P < 0.01). Blood glucose level in the AG group was higher than that in the WJTC prevention group (P < 0.05), but was not significantly different from that in the non-treated group (P > 0.05).

CONCLUSIONWJTC might prevent diabetic peripheral neuropathy by decreasing blood glucose and inhibiting AGEs formation in sciatic nerve in STZ-induced diabetic rats.

Objective To investigate the kinetic changes of inflammatory cell infiltration and thyroid autoantibodies in the development of iodine-induced autoimmune thyroiditis in NOD.H-2~(h4)mice.Methods Either 128 five-week-old NOD.H-2~(h4)mice or 128 Kunming mice were randomly divided into two groups,and received plain water or water containing 0.05% sodium iodide.At the time points of 1,2,4,8,12,16,and 24 week after receiving iodinated water,mice were anesthetized by diethyl ether and bled from eye socket vein,and their thyroid glands were collected.Indirect ELISA method was used to measure the levels of serum thyroglobulin autoantibodies (TgAb)and thyroid hormone.After being fixed with paraformaldehyde and embedded in paraffin,thyroid sections were stained with HE and used for morphometrieal analysis.Results In the iodine treated group of NOD.H-2~(h4) mice,autoimmune thyroiditis was observed as early as 1 week after they began receiving indinated water.The prevalence as well as the degree of autoimmune thyroiditis reached the maximum at 12 weeks and remained until 24 weeks.Serum TgAb level increased after 8 weeks of iodine ingestion in NOD.H-2~(h4) mice,then increased steadily throughout the 24 weeks of experiment.On the contrary,serum TgAb was not increased in the control group of Kunming mice.Conclusion Iodine may induce and exacerbate lymphocytic infiltration of the thyroid in genetically susceptible NOD.H-2~(h4) mice,and serum TgAb is just a marker of autoimmune thyroiditis.

OBJECTIVETo analyze the clinical characteristics of 267 cases with occupational chronic carbon disulfide (CS(2)) poisoning and to provide the basis for revising the items of periodical medical examination of workers occupationally exposed to CS(2).

METHODSThe subjects of present study were 267 patients with mild CS(2) poisoning diagnosed according to "Diagnostic Criteria of Occupational Chronic Carbon Disulfide Poisoning (GBZ4-2002)" from April in 2006 to May in 2010. All patients were from the same chemical fiber factory. When a subject was diagnosed as patient with CS(2) poisoning, who should interview with questionnaire which included the illness and occupational history, symptoms, individual habits. The physical examination, nervous test, cardiovascular test, biochemical test and electromyogram were performed.

RESULTSThe rate of decreased motor conduction velocity was 87.3% (233/267 roots). The highest detection rate of slowing conduction velocity was the common peroneal motor nerve which was 48.6% (138/248 roots) and the second was median motor nerve with delay rate of 37% (155/419 roots). The main symptoms of the patients were neurasthenia, numbness and paresthesia. The rates of abnormal achilles tendon reflex and knee jerk reflex in patients were were 79.4% and 49.8%, respectively. The detected rates of patients with ST-segment changes and hypertension were 19.1% and 27.5%, respectively. The rates of hypertension, systolic pressure and diastolic pressure were 27.3%, 22.5% and 21.1%, respectively. The rates of lactate dehydrogenase (LDH), triglycerides (TG) and low density lipoprotein (LDL) were high. The detected rates of urine acid, indirect bilirubin and total bilirubin in male patients were higher than those in female patients. In addition, the abnormal detected rate of urea nitrogen and indirect bilirubin increased with exposure years.

CONCLUSIONOccupational chronic CS(2) poisoning mainly affects the nervous system, as well as liver and kidney function. Detecting the median and common peroneal motor nerve conduction velocities could be the screening indicators for the peripheral nerve injury induced by CS(2) in the occupational exposure population during the periodical occupational medical examinations.

Percutaneous osteoplasty (POP) as a technical extension of percutaneous vertebroplasty (PVP) has been used to treat malignant disease that affects the skeletal system. POP has demonstrated good outcome for pain relief and functional improvement. Few studies have reported on the efficiency of POP to treat malignancies located in the femoral head. We designed a pilot study with the use of POP to treat intractable pain caused by a femoral head metastatic tumor in a 43-year-old man. During the follow-up period, the patient experienced sustained pain relief and improvement of quality of life that persisted for more than three months.

OBJECTIVETo investigate the changes in plasma levels of thrombomodulin (TM) and D-dimer (DD) in children with different types of Mycoplasma pneumoniae pneumonia (MPP), and their role in the pathogenesis of MPP in children.

METHODSFifty-two children with MMP were divided into lobar pneumonia (n=30) and interstitial pneumonia groups (n=22) and another 30 healthy children were selected as the control group. Plasma levels of TM and D-D were measured using enzyme-linked immunosorbent assay and latex-enhanced immunoturbidimetric assay, respectively.

RESULTSThe lobar pneumonia, interstitial pneumonia and control groups had median plasma TM levels of 23.83, 15.56 and 8.78 μg/L respectively, with significant differences between the three groups (P<0.01). The lobar pneumonia and interstitial pneumonia groups had significantly higher plasma TM levels than the control group (P<0.01), and the lobar pneumonia group had a significantly higher plasma TM level than the interstitial pneumonia group (P<0.05). Median plasma D-D levels in the lobar pneumonia and interstitial pneumonia groups were significantly higher than the reference value (P<0.01). The lobar pneumonia group had a significantly higher plasma D-D level than the interstitial pneumonia group (0.35 μg/mL vs 0.13 μg/mL; P<0.01), and the percentage of patients with elevated plasma D-D levels was significantly higher in the lobar pneumonia group than in the interstitial pneumonia group (87% vs 59%; P<0.05).

CONCLUSIONSChildren with MPP, especially those with lobar pneumonia, have increased plasma levels of TM and D-D. This suggests that damage to vascular endothelial cells and blood hypercoagulability may be involved in the pathogenesis of MPP.
