Objective To evaluate the therapeutic effect of laser induced chorioretinal venous anastomosis on macular edema of non ischemic retinal vein occlusion. Methods Thirty seven eyes of 37 cases of non ischemic retinal vein occlusion received the treatment of laser induced chorioretinal venous anastomosis and were followed up for 6～12 months. All affected eyes underwent the clinical examinations of visual acuity, ocular fundus photography, fundus fluoreceine angoigraphy (FFA) and light sensitivity of central 5 degree of the retina, and the pre and post operative clinical materials were analyzed. Results Successful chorioretinal venous anastomosis was formed in 18 eyes (48.6%) within 2 months after laser photocoaglation, with the mean best improved corrected visual acuity of (4 25?0 46) lines, while the mean best corrected visual acuity of the other 19 eyes with unsuccessful anastomosis decreased (0 20?0 54) lines ( P

BACKGROUND: Mesenchymal stem cells (MSCs) have the abilities of self-renewal, multidirectional differentiation and immunomodulation, and have become the focus of current research. OBJECTIVE: To summarize the immunomodulation of MSCs to different immune cells and the clinical applications of MSCs in the treatment of immune-related diseases. METHODS: The first author searched the PubMed and the CKNI databases for relative articles from January 1974 to December 2016. The key words were mesenchymal stem cells, immunomodulation, MSC1 and MSC2, autoimmune diseases in English and Chinese, respectively. Finally, 52 representative articles were included. RESULTS AND CONCLUSION: MSCs can inhibit the function of T lymphocytes, reduce the activation, proliferation and antibody secretion of B lymphocytes, affect the polarization of macrophages, inhibit the maturation of dendritic cells, inhibit the proliferation and toxicity of NK cells, so MSCs have the great potential in the treatment of immune-related diseases. However, MSCs exhibit the opposite immunomodulatory abilities under different inflammatory microenvironments, and moreover the definite and controllable mechanism of this phenomenon is still unclear, Therefore, future investigations may focus on the specific mechanism of MSCs in the clinical treatment of immune-related diseases.

Objective To observe the clinical efficacy and safety ofZhilou Lotion combined with modified Sihuang Ointment in treatment of anal cryptitis.MethodsOne hundred patients with anal cryptitis were randomly divided into observation group and control group, with 50 cases in each group. The control group was given propylene dispersible tablets oral and topicalHuazhi embolism. The observation group received steaming and hip bath with Zhilou Lotion combined with modifiedSihuang Ointment topical external application treatment, 7 days as a course of treatment and 2 courses successive. The TCM syndrome scores of two groups were compared before and after treatment to evaluate the clinical efficacy. The remission time of symptoms, hospitalization time, recurrence rate in 6 months and adverse reactions were observed.Results After treatment, the TCM syndrome scores of two groups were improved (P<0.01), and the scores in the observation group was lower than those in the control group (P<0.01). The total effective rate was 96.0% (48/50) in the observation group, and 80.0% (40/50) in the control group, with statistical significance (P<0.01). The remission time of anal edema, anal dampness, anal pain and anal fall-swell in observation group was obviously shorter than that in the control group, with statistical significance (P<0.01). The average hospitalization time was (15.25±2.78) days in the observation group and (18.46±3.41) days in the control group, the difference was significant (P<0.01). In the observation group, the recurrence rate was 0, 0 and 2.0% in 2, 4, 6 months follow-up, while that was 4.0%, 12.0% and 16.0% in the control group, respectively. The recurrence rates of the control group in 4 months and 6 months were higher than those of the observation group (P<0.05). No significant adverse reactions occurred in the two groups.Conclusion Zhilou Lotion combined with modifiedSihuang Ointment has good clinical efficacy in treatment of anal cryptitis, with low recurrence rate and high safety.

Objective To determine the safety, pregnancy outcome and the affect on neonates in pregnant patients with systemic lupus erythematosus(SLE).Methods Sixty-two pregnant patients with SLE were evaluated retrospectively from 1999 to 2009 in our hospital. These patients were divided into two groups:selective pregnancy group and nonselective pregnancy group. The pregnancy outcomes, fetal outcomes, and lupus activity during pregnancy were compared between the two groups. The children of the SLE patients were followed up. Results There were 43 patients in the selective pregnancies group and 19 patients in nonselective pregnancies group. In the selective pregnancies group, lupus flare occurred in 10 pregnancies(23%), 35(81%)had a live birth, 7 had low birth weight infants and 7 had premature delivery; however, in the nonselective pregnancies group, lupus flare occurred in 16 pregnancies(84%), 13(68%) had abortion,6 had a live birth, but all neonates were low birth weight infants. The rates of lupus flare and pregnancy loss in the nonselective pregnancy group were higher than those of the selective pregnancy group(P＜0.05). None of the 22 children had SLE during the follow-up period. Conclusion Both selective and nonselective pregnancy may adversely affectmaternal and fetal outcomes, but patients with selective pregnancy have better outcomes either in lupus flare or maternal and fetal outcomes compared with those of the nonselective pregnancy.

Objective To study the application value of serum umbilical cord blood bilirubin and hemolysis three test in the prediction of neonatal hyperbilirubinemia.Methods 1 200 cases of healthy newborn were selected,whose mothers were type O blood and fathers were not type O blood.According to the situation of maternal and infant blood type,they were divided into the same maternal and child blood type group with 539 cases and different blood type group with 661 cases;According to the umbilical cord blood bilirubin concentration range was divided into five groups,and analyzed umbilical cord blood bilirubin and hemolysis three test in the prediction of neonatal hyperbilirubinemia.Results (1) The concentrations of umbilical cord blood bilirubin,the incidence of ABO-HDN,the incidence of hyperbilirubinemia in the maternal-fetal blood(O-A/B) group were (38.1 ± 10.3) μmol/L,47.35％,26.02％,respectively,which were all significantly higher than (33.4 ± 7.9)μmol/L,15.21％,14.66％ in the maternal blood type (O-O) group (t =5.8,x2 =120.7,x2 =20.1,all P =0.000) ; (2) When the concentrations of umbilical cord blood bilirubin was higher,the incidence of hyperbilirubinemia was higher,but the sensitivity and the specificity both were bad; (3) According to the result of hemolysis three to predict the neonatal hyperbilirubinemia,when the concentrations of umbilical cord blood bilirubin was less than 21μmol/L or more than 55μmol/L,the positive predictive value and the specificity both were 100.00％,and the sensitivity was not low(75.00％ and 86.96％).Conclusion Detection of umbilical cord blood bilirubin and hemolysis three test in the maternal-fetal blood group incompatibility could predict early hyperbilirubinemia of newborn,which had certain clinically practical value.

BACKGROUND:Individuals with different vertical facial types have different chin morphologies. For the individuals with different vertical facial types, what is the most beautiful chin morphology?
OBJECTIVE:To evaluate the effects of vertical facial types and chin morphology on facial profile attractiveness.
METHODS:Three beautiful females were selected, including one with high mandibular angle, one with average angle and one with low angle. Their facial profile photographs were taken. A series of new pictures were generated by the smal scale (2 mm per unit) modification of soft tissue chin in the sagittal direction and vertical direction. Raters consisting of 17 orthodontists and 35 laypersons were selected for aesthetic ratings, in order to evaluate the facial profile attractiveness of the individuals with different vertical facial types.
RESULTS AND CONCLUSION:There was no esthetic difference of vertical change in female with high angle;while slightly protrude chin was perceived to be more beautiful than retruded chin. For the female with average angle, lower chin was more attractive than higher chin;slightly protruded chin was beautiful than excessive protruded chin and retruded chin. For the individual with low angle, higher chin was preferred by raters;slightly protruded chin was more beautiful than excessive protruded chin and retruded chin.The results indicate that the effects of vertical facial types and chin morphology to facial profile attractiveness are different. In clinical orthodontic, vertical facial types should be taking into consideration to change the chin morphology of the patents, in order to obtain better profile attractiveness.

This paper is to report the study of the metabolism of lidamycin in vitro including in plasma and microsomes to guide clinical therapy. Lidamycin was quantified by detecting its active ingredient using HPLC-MS/MS. The metabolic stability of lidamycin in rat, Beagle dog, monkey and human plasma and liver microsomes, and its inhibition to cytochrome P450 isoforms in human liver microsomes were studied. Results showed that lidamycin was metabolized in the four species of plasma, and the sequence of metabolic rates in plasma were in rat > in dog > in human > in monkey. But among the four species of liver microsomes, lidamycin was metabolized only in monkey liver microsomes. There was almost no inhibition to cytochrome P450 isoforms at the concentrations of between 0.0005 and 10 ng x mL(-1). Therefore, the property of lidamycin metabolism in human is similar with that in dog, and metabolism of other drugs would not be decreased by cytochrome P450 as used along with lidamycin in clinic.

Objective To explore the enhancement effects and mechanisms of IL-32β on human cervical carcinoma cells C33A to hypoxic/hypoglycemic condition.Methods After cultured in hypoxia/hypoglycemic circumstance and normal circumstance for 20 hours respectively, the mRNA and protein expression of IL-32β in C33A cells were detected by real time-polymerase chain reaction (RT-PCR) and Western blotting respectively.Trypan blue stain was used to detect C33A cells viability in hypoxia/hypoglycemic circumstance and adding 10, 100,500 ng/ml IL-32β circumstance.The xenografted tumor of nude mice was established by intraperitoneal injection, and their volumes were tested for a given time after injecting 0, 1.0 mg/kg IL-32β.siRNA was used to construct IL-32β knockdown cells and detect the expression of VEGF.Results Under the hypoxia/hypoglycemic circumstance, the expressions of IL-32β mRNA were (6.12 ± 0.03) times of the normal circumstance (F =43.16, P ＜ 0.05), the expressions of IL-32β protein were (2.23 ± 0.04) times of the normal circumstance (F =22.32, P ＜ 0.05).The C33A cells viability in hypoxia/hypoglycemic circumstance was (51.92 ± 3.41) ％, whereas, viability in 10 ng/ml IL-32β group was (55.23 ± 3.92) ％ (F =14.25, P ＜ 0.05), viability in 100 ng/ml IL-32β group was (62.52 ± 4.14) ％ (F =35.53, P ＜ 0.01), viability in 500 ng/ml IL-32β group was (69.14 ± 2.45) ％ (F =56.28, P ＜ 0.01).After 28 days, the volume of xenografted tumor of 0 mg/kg IL-32β group was (578 ± 64)mm3, and 1.0 mg/kg IL-32β group up to (1 402 ± 142) mm3 (F =27.84, P ＜ 0.01).In addition, compared with control group, the expression of VEGF in IL-32β knockdown C33A cells was significantly decreased (F =36.85, P ＜ 0.05).Conclusion IL-32β can enhance the resistance to hypoxic/hypoglycemic condition of C33A cells, which is associated with the increase of VEGF.
