?AIM: To investigate NO levels in tears and anterior chamber inflammation after phacoemulsification and intraocular lens implantation with trabeculectomy through different operative incisions.?METHODS: Totally 49 patients ( 50 eyes ) with primary acute angle - closure glaucoma and cataract were randomly divided to single-incision group and double-incision group. Both were treated by phacoemulsification and intraocular lens implantation and trabeculectomy after routine IOP-lowering drugs treatment. Preoperative and postoperative NO levels in tears were compared, and the aqueous flare and cells were examined using a laser flare-cell meter ( LFCM) .?RESULTS:Postoperative tear NO was 9. 86±0. 78μmol/L in single-incision group , it was 9. 13 ± 0. 67μmol/L in double-incision group, the differences was statistically significant(t=3. 57,P<0. 05). Postoperative aqueous flare values was 62. 42±18. 16 pc/ms in single-incision group;it was 52. 20 ± 17. 57 pc/ms in double-incision group, the differences was statistically significant(t=2. 02, P<0. 05).?CONCLUSION: The early inflammatory injury of double-incision was significantly lower than that of single -incision. It has the advantages of safety. But the surgical skill should be improved to less the injuries caused by operations.

Observed index is a very important element in a research design, because it is a specific reflection of the effects of research factors on the research subjects and is indispensable in any research. Generally, there are two types of observed indexes: the indexes that reflect natural attributes, habits or states of the research subjects and the indexes that reflect the effects of different drugs or treatments on research subjects. This article mainly introduces the definition, characteristics, selection and observation of research indexes and the major and minor indexes.

OBJECTIVETo observe the therapeutic efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined Wenshen Xiaozheng Decoction (WXD) in auxiliary treating endometriosis after laparoscopy.

METHODSOne hundred and thirty-four endometriosis patients with confirmative pathological diagnosis were assigned to three groups depending on whether they would receive adjuvant therapy or Chinese medicine treatment, i.e., the control group, the observation 1 group, and the observation 2 group. The 22 patients in the control group received no adjuvant therapy after laparoscopy. The 42 patients in the observation 1 group were treated with GnRHa 3.6 mg by subcutaneous injection starting from the 1st day to the 5th day of menstruation, once per 28 days. The 70 patients in the observation 2 group were treated with GnRHa 3.6 mg by subcutaneous injection in combination with WXD starting from the 1st day to the 5th day of menstruation, once per 28 days. They also took WXD for 7 doses, one cycle per every 28 days. The treatment lasted for three to six months. Serum levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cancer antigen 125 (CA125), as well as clinical efficacy, and adverse drug reactions were observed before and after treatment.

RESULTSThere was statistical difference in serum levels of E2, FSH, or LH between the control group and the observation 1 and 2 groups (P < 0.05). There was no statistical difference in serum levels of E2, FSH, or LH between the observation 1 group and the observation 2 group (P > 0.05). There was statistical difference in the clinical efficiency among the 3 groups (P < 0.05). There was statistical difference in the pre-post difference of CA125 levels among the three groups (P < 0.01). Compared with the control group, there was no statistical difference in the pre-post difference of CA125 levels between the observation 1 group and the observation 2 group (P > 0.05). No obvious adverse reaction occurred during the treatment.

CONCLUSIONSGnRHa combined WXD showed confirmative clinical efficacy in treating endometriosis after laparoscopy. It also could lower serum levels of E2, FSH, and LH levels. So it was an ideal solution for treatment of endometriosis.

Persicae Semen (PS), a traditional Chinese medicine, has been widely used for the syndrome of blood stasis in China since the Eastern Han Dynasty. In the present study, we developed an HPLC-UV fingerprint analysis method for the quality control of PS. The HPLC fingerprint was performed on Shimadzu Inertsil C18 column (4.6 mm x 250 mm, 5 microm) at 35 degrees C. The mobile phases were composed of acetonitrile and water using a gradient elution. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 210 nm. The fingerprint method was validated according to the Guidelines for Traditional Chinese Medicine Injection Fingerprint, and applied to determine 41 batches representative herbs collected from Xinjiang of China. The chromatographic peaks were characterized by UPLC-Q-TOF-MS, and nine of them were identified by comparison with the literature and/or reference standards. In order to classify and assess the samples, hierarchical clustering analysis and partial least square discriminant analysis were performed based on the common chromatographic peaks, and the samples were geographically classified into two classes, with six chemical compounds as classification markers which were significantly different between the two classes (P < 0.05).
