OBJECTIVE:To provide reference for the instructions of domestic Clindamycin phosphate injection. METHODS:The contents in the instructions of domestic Clindamycin phosphate injection approved the listing from Jan. 2006 to Dec. 2015 were statistically investigated according to Regulation for Drug Package Inserts and Label Management and Regulatory Guidelines for Chemicals and Biologicals,and the items with great differences in different approval number were analyzed comparatively. RE-SULTS:The labeling rate of clinical experiment in the collected 25 instructions of domestic Clindamycin phosphate injection was 0,the labeling rate of validity was 44%,the labeling rate of use for elderly patients was 68%,the labeling rate of overdosage was 76%,and the labeling rate of others was 100%. The items with great differences were mainly special populations,usage and dos-age,adverse reactions,validity,storage conditions and precautions. CONCLUSIONS:There are great differences in instructions of domestic Clindamycin phosphate injection,some items are inaccurate,incomplete and lack of scientificity,which may result in ir-rational drug use in patients and increase the risk of medication. It is suggested that the domestic enterprises should modify and per-fect the contents of the instructions of domestic Clindamycin phosphate injections referring to the instructions of foreign brand name drug;and the drug regulatory department should strengthen the monitoring of drug instructions.

The pancreatic tissues from patients with islet cell hyperplasia,insulinoma,and pancreatic adenocarcinoma,as well as normal pancreatic tissues were embedded with paraffin,serial sections were cut and mounted on glass slides.Immunohistochemical staining was carried out with N-myc down-stream regulated gene 2 (Ndrg2) monoclonal antibody by means of ABC method,and Western blotting was carried out to detect the expression and distribution of Ndrg2.The results showed that Ndrg2 positive immunoreactivity was mainly localized in the cytoplasm of islet cell,being similar to the localization of insulin positive immunoreactivity.The number and volume of pancreatic islets were increased in the patients with islet cell hyperplasia,and Ndrg2 expression was also increased.Western blotting results showed that the expression of Ndrg2 in the pancreas of patients with islet cell hyperplasia was increased compared with normal group.The above results suggest that Ndrg2 may play an important role in performing physiological function of islet cells.

Objective: To study the chemical constituents of the stem of Camellia oleifera. Methods: The chemical constituents were isolated and purified by column chromatography on silica gel, ODS, Sephadex LH-20, and PHPLC. Their structures were elucidated on the basis of physicochemical properties and special analysis. Results: Three compounds were isolated from the stem of C. oleifera and elucidated as 3-O-β-D-galactopyranosyl-(1→2)-[β-D-galactopyranosyl-(1→2)-β-D-xylopyranosyl-(1→3)]-β-D-glucuronopyranosyl-3β,15α, 16α,22α,28-pentol-22-O-angeloyloxy-olean-12-ene (1), camelliasaponin B2 (2), gordonsaponin H (3). Conclusion: Compound 1 was a new compound, and compounds 2 and 3 were isolated from the stem of this plant for the first time.

OBJECTIVE: To analyze the general and forensic pathological characteristics of death due to fat embolism syndrome (FES) and to provide reference data for forensic identification. METHODS: Twenty autopsy cases due to FES were selected from the forensic center of a medical college from 1999 to 2012. The general and forensic pathological characteristics such as the ways and types of injuries, clinical manifestation and the pathological changes were summarized. RESULTS: Fat embolism mainly occurred after long bone fracture or a large area of soft tissue injury with the majority of cases being fat embolism of lung and occasional cases being combined embolisms of lung and brain as well. The onset of symptoms appeared shortly after the injury or surgery. Lipid droplets could be observed within small pulmonary vessels and verified by special staining. CONCLUSION There are particular characteristics in death due to FES in concern with types of injuries, onset of symptoms and pathological findings. In order to find out the direct evidence of FES, special staining (oil red O staining) can be used in the forensic identification.

OBJECTIVETo develop a new technique for assessing the risk of birth defects, which are a major cause of infant mortality and disability in many parts of the world.

METHODSThe region of interest in this study was Heshun County, the county in China with the highest rate of neural tube defects (NTDs). A hybrid particle swarm optimization/ant colony optimization (PSO/ACO) algorithm was used to quantify the probability of NTDs occurring at villages with no births. The hybrid PSO/ACO algorithm is a form of artificial intelligence adapted for hierarchical classification. It is a powerful technique for modeling complex problems involving impacts of causes.

RESULTSThe algorithm was easy to apply, with the accuracy of the results being 69.5%±7.02% at the 95% confidence level.

CONCLUSIONThe proposed method is simple to apply, has acceptable fault tolerance, and greatly enhances the accuracy of calculations.

Objective To compare the effect of diversification rehabilitation team mode on function in patients with cerebral infarction. Methods Sixty-six patients with cerebral infarction were divided into diversification rehabilitation team mode group (diversification group) and routine rehabilitation mode (routine group) according to the rehabililation method with 33 cases each. All patients of 2 groups were treated for 2 weeks. Evaluations were made before and after treatment. The simplified Fugl-Meyer motor function rating scale was used to evaluate motor function, modified Barthel index was used to evaluate activities of daily living, and MOS 36-item short form health survey was used to evaluate quality of life;and 0-100 digital simulation assessment was used to evaluate patient satisfaction after treatment. Results The simplified Fugl-Meyer motor function rating scale score, modified Barthel index score, MOS 36-item short form health survey score and patient satisfaction rate after treatment in diversification group were significantly better than those in routine group: (76 ± 4) scores vs. (63 ± 3) scores, (65 ± 3) scores vs. (52 ± 4 ) scores, (57 ± 7) scores vs. (44 ± 6) scores, (92 ± 5) scores vs. (77 ± 3) scores, and there were statistical differences (P<0.05). Conclusions Both kinds of rehabilitation model can promote functional recovery in patients with cerebral infarction, but diversification rehabilitation team model is better than conventional model.

OBJECTIVE: To investigate the efficacy of combined medical treatment on auditory neuropathy spectrum disorder and the effect of related factors on the prognosis. METHOD: Eleven cases (22 ears) diagnosed as auditory neuropathy spectrum disorder using multiple criteria including pure tone auditory threshold, impedance audiometry, acoustic reflexes, distortion products otoacoustic emission (DPOAE) and auditory brainstem response (ABR) were subjected to combined medical treatment . Eleven auditory neuropathy spectrum disorder patients diagnosed during the corresponding period but refused treatment were selected as control group. The change of pure tone auditory threshold and speech discrimination score after treatment or follow-up were evaluated for both 2 groups, and the relationship between the patients' gender, age, accompanying symptoms and curative effect were also analyzed. Data were analyzed by SPSS 19.0 statistical software using pared-sample t-test, independent-sample test and Pearson's chi-square test. RESULT: The effective rate of combined medical therapy was 59.09% (13/22) in the therapy group. PTA levels before and after-treatment were (53.92 +/- 18.86) dB HL and (47.44 +/- 14.98) dB HL respectively in 22 ears with the combined medical therapy, the improvement of which showed statistically significance (t = 5.20, P < 0.05). No obvious hearing change was noted in the 11 patients who refused therapy (P > 0.05). Speech discrimination score before and after-treatment were (29.20 +/- 25.80)% and (41.60 +/- 22.90)% respectively for the treatment group. The average improvement of speech discrimination score was (12.40 +/- 13.80)% with statistically significant difference (t = 4.02, P < 0.05). Patients accompanied with tinnitus had relatively poorer effect compared with individuals without tinnitus (t = -3.85, P < 0.05). Age is negatively correlated with the prognosis (r = -6.72, P < 0.05). Gender had no effect on the prognosis (P > 0.05). CONCLUSION The combined medical therapy with glucocorticoids helps improving the pure tone auditory threshold and speech discrimination score of auditory neuropathy spectrum disorder. In light of our findings we support the combined medical therapy as an option for patients with auditory neuropathy spectrum disorder.
