Infectious endophthalmitis refers to the acute suppurative inflammation of the uveal and retinal, with acute onset, severe symptoms, and poor prognosis.Early diagnosis and effective treatment is particularly important.Based on the way of intraocular infection, endophthalmitis can be divided into endogenous endophthalmitis and exogenous endophthalmitis.In the East Asian, liver abscess is the main source of endogenous endophthalmitis, and Klebsiella pneumoniae is the main pathogen.Liver abscess endophthalmitis is a serious cause of blindness caused by intraocular infection.A liver infection disseminated through hematogenous and the primary focus was hidden, which makes the disease was easy to be confused with immune related uveitis, causing high misdiagnosis rate, delaying the best time for diagnosis and treatment.In this article we reviewed the etiology, clinical features, diagnosis and treatment and prognosis of endogenous endophthalmitis caused by liver abscess.Clinicians should maintain a high index of suspicion to the endogenous endophthalmitis caused by liver abscess.

OBJECTIVE: Moxibustion is one of the commonly used therapy of traditional Chinese medicine by applying burning dried mugwort on particular acupoints of the body surface. In the present paper，we reviewed progress of researches about the mechanisms of moxibustion treatment undering imporvement of blood circulation in recent 15 years. Research results displayed that moxibustion can dilate blood vessels to increase blood flow and improve microcirculation, not only in the local superficial vessels of body, but also in the deep tissues as the brain, stomach and mesentery, kidney, heart, etc., as well as in the distal blood vessels. The vasodilator action of moxibustion stimulation is related to nerve regulation, endothelium derived relaxing factors and vasodilator mediator, etc. through 1) interaction of acetylcholine (Ach)/muscarinic receptor (MR) and noradrenaline (NE)/α- or β-receptor; 2) nitric oxide synthase (NOS)/NO/arachidonic acid/prostacyclin (PGI2)/endothelium-derived hyperpolarizing factor (EDHF) pathway; 3) EDHF/TRPV 4/KCa channel, cytochrome P 450 oxidase/epoxyeicosatrienoicacid (EET); 4) EET/TRPV 4/big conductance calcium-activated potassium channel (BKCa); 5) sulfuretted hydrogen (H2S)/ATP-sensitive potassium channel (KATP) or voltage-gated potassium channels (Kv 7); 6) NO/substance P (SP) or CGRP and adrenergic β 2 receptor(R)/TRPV 1/adenosin A 1 R and A 2 R/NK 1 R pathway; 7) PGI2/adenylyl cyclase (cAMP)/PKA and vasoactive intestinal peptide (VIP), etc. in the vascular endothelium and smooth muscle. These research results may help us understand the effects and mechanisms of moxibustion in the treatment of different clinical conditions by improving microcirculation.

PURPOSE: Intestinal dysfunction is one of the most common complications in patients after abdominal surgery. Daikenchuto (DKT), a traditional herbal medicine, is recently employed to improve postoperative intestinal dysfunction. The aim of this meta-analysis was to assess the efficacy of DKT in improving intestinal dysfunction after abdominal surgery. METHODS: PubMed, Embase, and the Cochrane library were systematically searched to identify randomized controlled trails (RCTs) in adult patients undergoing abdominal surgery, who were randomly distributed to administrate DKT and placebo. The primary outcomes included the time to first postoperative flatus or bowel movement. We used random-effects models to calculate summary mean differences (MDs) with 95% confidence intervals (CIs). RESULTS: Nine RCTs totaling 1,212 patients (618 in DKT, 594 in control group) were included in our study. Compared with control group, DKT can effectively improve postoperative intestinal dysfunction by shortening the time to first postoperative flatus (MD, −0.41; 95% confidence interval [CI], −0.66 to −0.16; P = 0.001) with significant heterogeneity (I2 = 71%, P = 0.004), and bowel movement (MD, −0.65; 95% CI, −0.97 to −0.32; P < 0.001) without significant heterogeneity (I2 = 40%, P = 0.14). Sensitivity analyses by indication of surgery and type of surgery yielded similar results. CONCLUSION: These data provide limited evidence that DKT shows efficacy on improving intestinal dysfunction after abdominal surgery. However, the results should be interpreted cautiously, due to the heterogeneity of the studies included. Thus, the efficacy of DKT on improving postoperative intestinal dysfunction warrants further investigation.

OBJECTIVETo study the prevention and treatment of postoperative diabetes insipidus after removal of pituitary tumor through transsphenoidal operation, to decrease the incidence of postoperative complications and improve the treatment of pituitary tumor.

METHODSThe clinical data of 86 cases of transsphenoidal resection of pituitary tumor in recent 8 years were retrospectively reviewed, including 35 endoscopic operation and 51 microscopic operation. The incidence, prevention and treatment of diabetes insipidus were statistically analysed.

RESULTSThere were 18 cases of postoperative diabetes insipidus in total of 86 operations, including 15 acute cases, 3 delayed cases. Twelve were temporary , which recovered within 1 week. After prompt treatment, 14 recovered within 1 week, 4 recovered within 2 weeks. No persistent diabetes insipidus was found.

CONCLUSIONSThe key points to prevent postoperative diabetes insipidus lay in the improvement of operative skills, careful protection during operation and avoidance of unnecessary injury. In case of diabetes insipidus occurred, rational use of antidiuretics and correction of electrolyte balance were effective in the treatment of postoperative diabetes insipidus.

OBJECTIVE: To investigate the features and diagnosis way of small round cell tumor of nasal sinus and bases of skull. METHOD: A retrospective analysis of 123 case with small round cell tumor of nasal sinus and bases of skull were carried out in our hospital in past ten year. Clinical, histological, radiological and immunohistochemical characters of these cases were studied. RESULT: All cases usually complained of nasal obstruction, headache, diplopia, nasal mucus with bleeding, vision or weight loss. Expansible or infiltrative lumps were found in nasal sinus or bases of skull in radiological examination. A lot of small round cells were found in these tumors in histological pathology. At least 5-6 cell, tissue or tumor markers were examined immunohistochemically in most of cases before the final diagnosis were made. In some cases over 20 markers were examined. Five cases were carried out transmission electron microscope examination, special features such as desmosome and myofilament were found. CONCLUSION Clinical symptom, physical signs and radiological finding can supply malignant evidences of these tumors. Histological examination can make certain that they are small round cell tumors, but final diagnosis is still hard to make only by these. Immunohistochemical examination of various markers can tell the original characters of the specimen tissues, it is the key for final diagnosis. Transmission electron microscope examination is another helpful way for diagnosis.

OBJECTIVETo investigate the mRNA expressions of RASSF1A, Galectin-3 and TPO in papillary thyroid carcinoma and some other thyroid benign lesions, and evaluate their diagnostic significance.

METHODSReverse transcription polymerase chain reaction (RT-PCR) was used to detect the mRNA expression of RASSF1A, galectin-3 and TPO in the samples from 73 cases, including 23 cases with papillary thyroid cancer, 16 with nodular goiter, 29 with thyroid adenoma and 5 with Hashimoto's disease.

RESULTSA statistically significant difference in the mRNA expression of RASSF1A, Galectin-3 and TPO was observed between papillary thyroid carcinoma and follicular benign lesions (P<0.05). However, there was no significant difference among various kinds of benign lesions (P>0.05). A negative correlation of the expression of RASSF1A and Galectin-3 mRNA was found between thyroid benign lesions and malignant ones (P = 0.000). While the mRNA expression of RASSF1A and TPO was positively correlated between benign and malignant lesions (P = 0.028).

CONCLUSIONLoss of expression of RASSF1A and TPO mRNA but high expression of Galectin-3 mRNA in papillary thyroid carcinoma are common. Therefore, the products of these three genes may be closely related to the development of thyroid papillary carcinoma, and may be used as useful markers in differential diagnosis of papillary thyroid carcinoma from the benign lesions. The results are more reliable if this detection method is used in combination with other techniques.

OBJECTIVETo investigate the biological effects of overexpression of the human DNA polymerase (pol-beta) on cellular response to DNA damage.

METHODSThe cell strain HLFbeta from the stable overexpression of the human pol-beta was contaminated with methyl methanesulfonate (MMS) for investigating the effects of the pol-beta on the cellular responses to DNA damage on the aspects such as the DNA damage, the cell cycle and the induced mutation rate.

RESULTSThe cell HLFbeta from the stable overexpression of the human pol-beta was obtained through the screening. The cellular response to DNA damage of HLFbeta induced by the MMS in the intermediate and high dosage group (ranging from 0.5 to 0.8 mmol/L) was significantly lower than that in the control group. The analysis for the cell cycle distribution showed that both the two types of cells contaminated by MMS had retardation at G(2) phase. In the HLFbeta group, the cells had the obvious G(2) phase retardation and 49.0% of the cells were retarded at G(1) phase as well when the MMS was increased to 0.5 mmol/L while in the control, only 20.1% of the cells were retarded at the G(1) phase when the same dosage of MMS was administered. Moreover, the MMS-induced mutagenesis in HLFbeta was increased from 4.5 x 10(-6) to 8.2 x 10(-6), significantly higher than that in the control group (P < 0.05).

CONCLUSIONHigh Pol-beta level decreases cellular DNA damage induced by MMS. Nevertheless, the overexpression of Pol-beta can also increase error-prone DNA synthesis during DNA repair process.

OBJECTIVETo observe the induction of apoptosis of cisplatin (DDP) to oral squamous cell carcinoma cell line (Tca8113) in vitro and study the role of Survivin on the apoptosis of Tca8113 cells induced by cisplatin.

METHODSThe inhibitory effects of different doses of DDP on Tca8113 cells were assayed with MTT test. Apoptosis was determined by flow cytometry. The expression of Survivin was detected by RT-PCR and immunocytochemistry.

RESULTSCisplatin obviously inhibited Tca8113 cells growth in a dose and time dependent manner. The apoptotic index showed the similar trend. Survivin gene expression was decreased with increasing of time and reached the lowest level at 24 hours after DDP treatment, then increased after that time.

CONCLUSIONCisplatin gene can effectively induce apoptosis in Tca8113 cells and the inhibition of Survivin gene expression may play a critical role on Tca8113 cell apoptosis induced by cisplatin.
