Background Neovascular glaucoma (NVG) is a serious ocular disease which may cause blindness.The primary pathogenesis of NVG is ischemic retinopathy derived by central retinal vein occlusion (CRVO) and diabetic retinopathy (DR).Clinical characteristics of NVG are variable based on the difference of primary diseases,such as CRVO and DR.However,there is a few studies regarding the diffcrcnces of NVG initiated by CRVO and DR.Objective This study was to compare the clinical characteristics in NVG patients secondary to CRVO and DR.Methods A series case observational study was carried out in Hiserve Hospital of Qingdao University from January 2009 to June 2012.Twenty-nine eyes of 27 patients with NVG caused by CRVO (10 eyes of 10 patients) and DR (19 eyes of 17 patients) were included.The history of underlying diseases,course of NVG,intraocular pressure(IOP),fundus findings and complications after treatment were analyzed and compared between the CRVO-derived NVG and DR-derived NVG.All patients underwent panretinal photocoagulation,improving microcirculation therapy,anti-glaucoma (drug or surgery) and causative disease treatment,and some of them received vitrectomy or/and cataract surgery.Two eyes from each group received intravitreal injection of ranibizumab.The follow-up time in both groups was (14.00±10.13) months and (17.89±12.52) months,respectively.Results The median time of underlying disease was 3.3 months (2 weeks to 6 months) in the CRVO patients and 11.1 months (4 to 36 mouths) in the DR patients,with a significant difference between them (Z =-2.40,P＜0.05).CRVO-derived NVG progress was much faster than that of DR-derived NVG.The number of the eyes with visual acuity improvement after treatment was 2 in the CRVO-derived NVG and 15 in the DR-derived NVG;while the number of the eyes with unchanged or worse visual acuity was 8 and 4 in the CRVO-derived NVG eyes and the DR-derived NVG eyes (x2 =9.38,P＜0.01).The difference of IOP in pre-and post-treatment was (37.00±9.91)mmHg in the CRVOderived NVG eyes and (8.92±12.05)mmHg in the DR-derived NVG eyes,showing a significant difference between them (t =6.30,P＜0.01).In the CRVO-derived NVG eyes,optic disc edema,retinal hemorrhage,and vein dilatation were seen in 6 eyes,and mild optic disc edema and retinal hemorrhage were observed in 4 eyes.After treatment,fundus could not be seen in 4 eyes,in other 2 eyes optic disc and retinal laser spots were unclearly observed.In addition,pale optic disc and retinal vessel occlusion appeared in 2 eyes,and silver wire-like arteries exhibited in 2 eyes.In pre-treated DR-derived NVG eyes,fundus could not be seen in 8 eyes and Ⅲ-Ⅳv stages of DR findings appeared in 11 eyes.After treatment,retinopathy was stabilized in 16 eyes of 15 cases.Advanced retinopathy(V-Ⅵ stages of DR findings) was revealed in 3 eyes of 3 cases.The incidence of the complication after treatment was 100.0％ in the CRVO-derived NVG eyes and 21.1％ in the DR-derived NVG eyes (x2=5.18,P＜0.05).Conclusions The clinical characteristics of NVG secondary to CRVO and DR are variable,an appropriate treatment option should be selected according to different features of NVG.

This study was aimed to explore the expression of 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) in 3 different lymphoblastic cell lines with relation to their glucocorticoid (GC) sensitivity. The 11β-HSD2 expressions in acute lymphoblastic leukemia Jurkat cells, lymphoma Daudi and Raji cells, and peripheral blood T cells of a healthy volunteer were analyzed by real time PCR and Western blot. Glucocorticoid (GC)-induced apoptosis in 3 different cell lines was detected by flow cytometry. Cell growth in Jurkat cells treated with cortisol was analyzed by trypan blue dye exclusion. Flow cytometry was performed to observe GC-induced apoptosis in Jurkat cells treated by combination of GC with 11β-HSD2 inhibition 18β-glycyrrhetinic acid (18β-GA). The results demonstrated that 11β-HSD2 highly expressed in Jurkat cells, but not in Daudi, Raji cells and normal blood T cells. Compared to Daudi and Raji cells, Jurkat cells were more resistant to GC-induced apoptosis. Furthermore, the inhibition of 11β-HSD2 by 18β-GA resulted in increased cellular sensitivity to GC as shown by elevated induction of apoptosis. it is concluded that 11β-HSD2 is at least partly responsible for GC resistance in Jurkat cells. 11β-HSD2 may be a potential target for reduction of GC-resistance in therapeutic applications.

OBJECTIVETo ascertain whether other variations coexist with 1555(A--> G) mutation in the mitochondrial DNA and may aggravate the severity of hearing loss or increase the penetrance of 1555(A--> G) mutation in a large family with maternally inherited nonsyndromic deafness in Huaiyin, Jiangsu province.

METHODSPCR-restriction fragment length polymorphism (PCR-RFLP) was used to screen both the nt1555 and the nt7445 of the mitochondrial DNA from 27 maternal members in the core family; and then the mitochondrial genomes from two maternal members, and the 12S rRNA genes MTRNR1 and tRNA-Ser(UCN) gene MTTS1 from the others, were amplified by PCR-RFLP and were sequenced.

RESULTS1555(A--> G) mutation in the mitochondrial DNA was reverified to be one of the major factors which cause maternally inherited nonsyndromic deafness and the cosegregation of 955-960(insC) and 1555(A--> G) was present in this family. Moreover, 7449 (insG), a novel homoplasmic mutation in the tRNA-Ser(UCN) gene, was found to co-exist with 1555(A--> G) mutation in two maternal members.

CONCLUSIONThe cosegregation of 955-960(insC) and 1555(A--> G) implies that 955-960(insC) may synergistically cause hearing loss in the presence of an 1555(A--> G) mutation, serving as an aggravating factor to enhance the sensitivity to aminoglycosides, and may sometimes increase the penetrance of 1555(A--> G) mutation.

OBJECTIVETo investigate the effectiveness of testicular sperm cryopreservation in male fertility preservation by evaluating the clinical outcome of ICSI cycles with frozen-thawed testicular sperm for azoospermia patients.

METHODSWe retrospectively analyzed 96 samples of cryopreserved testicular sperm obtained by testicular biopsy, vasovasostomy (V-V), vasoepididymostomy (V-E) , of which 55 were subjected to 60 ICSI cycles with frozen-thawed testicular sperm. We evaluated the rates of sperm recovery, fertilization, cleavage, transferable and good-quality embryos, clinical pregnancy, pregnancy outcome, and health of the newborns.

RESULTSAll the frozen testicular sperm samples were recovered successfully. The rates of fertilization, 2PN fertilization, cleavage, available embryos and good-quality embryos were 77.6, 69.4, 99.4, 84.5 and 40.8%, respectively. There were transferable embryos in all cycles. Fresh embryos were transferred in 52 of the 60 cycles, with the clinical pregnancy rate of 57.7% (30/52), including 19 singletons and 11 twins, and the rates of implantation and miscarriage were 38.7% (41/106) and 3.33% (1/30). Up to the present time, there have been 20 healthy newborns, including 12 boys and 8 girls, and another 13 ongoing pregnancies. No birth defects have been found so far.

CONCLUSIONDesirable clinical outcomes can be obtained from ICSI cycles with frozen-thawed testicular sperm, and testicular sperm cryopreservation is an effective method of fertility preservation for azoospermia males.

OBJECTIVETo explore the method of digestive tract reconstruction and postoperative management in the upper abdominal multivisceral transplantation (MVT).

METHODSThe data of a pancreatic cancer patient with multiple liver metastases, undergone the first upper abdominal MVT in Asia on May 2004, was investigated retrospectively.

RESULTSDuring the operation, liver, gall bladder, pancreas, duodenum, part of jejunum, total stomach, greater and lesser omentum, and spleen were all resected from the recipient. Roux-en-Y procedure was adopted for the reconstruction of digestive tract, including closing the proximal end of donor duodenum, anastomosing recipient jejunum with horizontal part of donor duodenum, transecting the jejunum 35 cm from the anastomosis, end-to-side anastomosing the distal cut end of jejunum with the end of esophagus, and end-to-side anastomosing proximal cut jejunum with jejunum 50 cm away from esophageal anastomosis. Drainage tube was left inside duodenum and jejunum stoma was made for nutrient canal.The endocrine of pancreas was suppressed by the use of somatostatin postoperatively. Removing of nasogastric tube and duodenum draining tube were delayed. Bowel function recovered 4 days postoperatively and gradually resumed ordinary diet. One month after operation, the patient had no other complications except diarrhea.

CONCLUSIONThe success of upper abdominal MVT supplies precious experience in digestive tract construction and postoperative management.

Background: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This study assessed the efficacy and safety of tofacitinib in Chinese patients with RA enrolled in Phase 3 and long-term extension (LTE) studies. Methods: ORAL Sync was a 1-year, randomized, placebo-controlled, Phase 3 trial. Patients received tofacitinib 5 or 10 mg twice daily (BID) or placebo advanced to tofacitinib 5 or 10 mg BID at 3 or 6 months. All patients remained on ≥1 background conventional synthetic disease-modifying antirheumatic drug. ORAL Sequel is an open-label LTE study (data-cut: March 2015; data collection and analyses were ongoing, and study database was not locked at the time of analysis; study was closed in 2017). Efficacy outcomes: American College of Rheumatology (ACR) 20/50/70 response rates and Disease Activity Score in 28 joints using erythrocyte sedimentation rate (DAS28-4 [ESR]). Patient- and physician-reported outcomes: Health Assessment Questionnaire-Disability Index (HAQ-DI), Patient and Physician Global Assessment of Arthritis, and pain (visual analog scale). Safety was assessed throughout. Results: ORAL Sync included 218 patients; 192 were subsequently enrolled into ORAL Sequel. In ORAL Sync, more patients achieved ACR20 (tofacitinib 5 mg BID, 67.4%; 10 mg BID, 70.6%; placebo, 34.1%) and DAS28-4 (ESR) <2.6 (tofacitinib 5 mg BID, 7.1%; 10 mg BID, 13.1%; placebo, 2.3%) with tofacitinib versus placebo at Month 6. Mean changes from baseline in HAQ-DI were greater with tofacitinib versus placebo at Month 6. In ORAL Sequel, efficacy was consistent to Month 48. Incidence rates for adverse events of special interest in tofacitinib-treated patients were similar to the global population. Conclusions: Tofacitinib significantly reduced signs/symptoms and improved physical function and quality of life in Chinese patients with moderate-to-severely active RA up to Month 48. The safety profile was consistent with the global population. Clinical Trial Identifier NCT00856544 and NCT00413699.

Since the 18th National Congress of the Communist Party of China(CPC), the CPC and the government have highligh-ted the development of traditional Chinese Medicine(TCM) and issued a series of policies, such as the Plan for Protection and Deve-lopment of Chinese Medicinal Materials(2015-2020) forwarded by the General Office of the State Council in 2015, the Plan for Healthy Development of Traditional Chinese Medicine(2015-2020) released by the General Office of the State Council in the same year, the Healthy China 2030 Plan published by the CPC Central Committee and the State Council in 2016, the Law of the People's Republic of China on Traditional Chinese Medicine which took effect on July 2017, On the Preservation and Innovative Development of Traditional Chinese Medicine promulgated by CPC Central Committee and the State Council in 2019, and Plan for the Development of Traditional Chinese Medicine during the 14th Five-Year Plan Period of China released by the General Office of the State Council in March 2022, to promote the development of the TCM industry, which have brought historical opportunities to the TCM industry. However, TCM industry faces various challenges in the development. In terms of drug development in TCM, the current studies mainly focused on the chemical research and technical requests, which neglected TCM characteristics and cased in conformity between new drug transformation of TCM and clinical practice. Therefore, a more considerable and profound authoritative guideline is needed, and innovative thought and research are necessary for academics and the industry. Through the investigation of the development TCM industry in recent years, this study summarized the policies on and trends of Chinese medicinal materials, new drug development in TCM, catalogue of national basic drugs, and national basic health insurance, and proposed suggestions for further development of TCM industry.
