Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective To characterize a species of the genus Tricula and parasitized trematodes in schistosomiasis-endemic areas of Yunnan Province using a molecular analysis, so as to understand their taxonomic positions. Methods Tricula spp. and Oncomelania snails were collected from Xiangyun County, Yunnan Province, and cercaria parasitizing snails were observed using crushing followed by microscopy. Cercaria parasitizing Tricula snails at various morphologies were sampled using a shedding method. Genomic DNA was extracted from snail soft tissues and cercariae, and the 16S rRNA, COI, 28S rDNA genes in snails and the ND1 and 28S rDNA genes in cercariae were amplified using a PCR assay and sequenced. The species of Tricula snails and their parasitized trematodes was characterized using sequence alignment and phylogenetic analysis. Results Among 382 Tricula snails detected, there were three types of trematode cercariae found, including the non-forked (20.94%, 80/382), double-forked (3.40%, 13/382) and swallow shapes (7.07%, 27/382). Sequence and phylogenetic analyses showed that the 16S rRNA, COI and 28S rDNA gene sequences of this species of Tricula had high homology to those in Delavaya dianchiensis, and were clustered in a branch. Sequencing analysis of the ND1 and 28S rDNA genes revealed that the non-forked cercariae belonged to the family Pleu- rogenidae, the swallow-shaped cercariae belonged to the family Opecoelidae, and the double-forked cercariae belonged to another species of the genus Schistosoma that was different from S. sinensium and S. ovuncatum. Conclusion The species and taxonomy of Triculla spp. and their parasitized trematodes are preliminarily determined in schistosomiasis-endemic areas of Yunnan Province; however, further studies are required to investigate the more definite taxonomy and pathogenicity.

The patients with severe traumatic brain injury(sTBI)have a higher incidence of epilepsy.It's controversial whether prophylactic antiepileptic drugs(AEDs)are needed to prevent epilepsy in sTBI.Patients with sTBI do not need prophylactic AEDs on the basis of analgesic and sedative treatment in the early stage(within 7 days),and prophylactic AEDs are also not needed in late stage.Patients diagnosed with epilepsy need to take AEDs.

A three-level (provincial, municipal and county levels) schistosomiasis diagnosis network platform had been created in Yunnan Province, and assessment of laboratory quality-control samples and field evaluation of nucleic acid diagnostic techniques and immunodiagnostic reagents had been performed. This paper described the review process of the schistosomiasis diagnosis network laboratory and the operation of schistosomiasis diagnosis network laboratory and analyzed the problems of the schistosomiasis diagnosis network laboratory in Yunnan Province. The establishment of the schistosomiasis diagnosis reference (network) laboratory will provide a strong support for schistosomiasis control in Yunnan Province in the new era.

The study was designed to investigate the effect of IMPDH1 gene polymorphism on the pharmacodynamics of mycophenolic acid in the renal transplant patients. 315 patients with renal transplantation were treated with triple immunotherapy (mycophenolic acid + tacrolimus + prednisone). The Agena MassARRAY assay was used to detect the IMPDH1 genotypes in patients above. The plasma drug concentration of mycophenolic acid (MPA) and its main metabolite mycophenolic acid glucuronide (MPAG) was detected by high performance liquid chromatography (HPLC). The correlation between IMPDH1 gene polymorphism (rs10954183, rs12536006, rs13242340, rs2278293, rs2288549) and rejection and postoperative infection in renal transplant recipients were analyzed by SPSS 21 software. The result showed that IMPDH1 rs2288549 GG is a risk factor for acute rejection after renal transplantation (P<0.05), and IMPDH1 rs2278293 CT is a risk factor for infection after renal transplantation (P<0.05). Above all, IMPDH1 rs2288549 is an important factor of acute rejection after renal transplantation, IMPDH1 rs2278293 is an important factor affecting the emergence of infection after renal transplantation. The SNPs may help to optimize clinical medication to reduce the incidence of adverse reaction.

Objective To master the prevalence status of schistosomiasis in Yunnan Province in 2016,so as to provide the evidence for formulating the control strategy and intervention measures. Methods The schistosomiasis heavy-endemic villages were selected from each of 18 endemic counties as the survey sites. Then,the serological and etiological tests were carried out in the local residents and floating population,and the infection status of the livestock,field feces and Oncomelania hupensis snails were surveyed. Results The serum positive rate of schistosomiasis of local residents was 8.78％and the serum positive rate was 2.26％of floating population. No schistosome eggs were found in the stool examinations in the population. The area with snails was 80.0546 hm2 in 2016 with an increasing rate of 45.47％compared to that in 2015. The average density of living snails was 0.0317/0.1 m2. No schistosome-infected snails were found for the last four years and no new area with snails was found for the last three years. No positive livestock or feces were found. Conclusions The schistosomiasis epidemic situation is stabilized in Yunnan Province in 2016. However,the area with snails and the number of living snails are increasing,and therefore,the schis-tosomiasis epidemic risk still exists. So,the comprehensive control measures should be strengthened continuously.

Objective: To study the safety and efficacy of Bushen Daozhuo Granules (BDG) in the treatment of type Ⅲ prostatitis. METHODS: This multicenter randomized controlled clinical trial included 478 patients with type Ⅲ prostatitis, 290 in the trial group and 188 as controls, the former treated with BDG at 200 ml bid and the latter with tamsulosin hydrochloride sustainedrelease capsules at 0.2 mg qd, both for 4 weeks. Before treatment, after 4 weeks of medication, and at 4 weeks after drug withdrawal, we obtained the NIH Chronic Prostatitis Symptom Index (NIHCPSI) scores and compared the safety and effectiveness rate between the two groups of patients. RESULTS: Compared with the baseline, the NIHCPSI score was markedly decreased in the control group after 4 weeks of medication (21.42 ± 4.02 vs 15.67 ± 3.65, P < 0.05) but showed no statistically significant difference from that at 4 weeks after drug withdrawal (19.03 ± 3.86) (P>0.05), while the NIHCPSI score in the trial group was remarkably lower than the baseline both after 4 weeks of medication and at 4 weeks after drug withdrawal (10.92 ± 2.06 and 12.91 ± 2.64 vs 21.58 ± 3.67, P < 0.05). The trial group exhibited both a higher rate of total effectiveness and safety than the control (P < 0.05). CONCLUSIONS BDG is safe and effective for the treatment of type Ⅲ prostatitis.

The etiology and pathogenesis of moyamoya disease (MMD) remain elusive. Some inflammatory proteins, such as cyclooxygenase (COX)-2, are believed to be implicated in the development of MMD. So far, the relationship between COX-2 and MMD is poorly understood and reports on the intracranial vessels of MMD patients are scanty. In this study, tiny pieces of middle cerebral artery (MCA) and superficial temporal artery (STA) from 13 MMD patients were surgically harvested. The MCA and STA samples from 5 control patients were also collected by using the same technique. The expression of COX-2 was immunohistochemically detected and the average absorbance (A) of positively-stained areas was measured. High-level COX-2 expression was found in all layers of the MCA samples from all 5 hemorrhagic MMD patients, while positive but weak expression of COX-2 was observed only in the endothelial layer of the MCA samples from most ischemic MMD patients (6/8, 75%). The average A values of COX-2 in the hemorrhagic MMD patients were substantially higher than those in their ischemic counterparts (t=4.632, P=0.001). There was no significant difference in the COX-2 expression among the "gender" groups, or "radiographic grade" groups, or "lesion location" groups (P>0.05 for all). The COX-2 expression was detected neither in the MCA samples from the controls nor in all STA specimens. Our results suggested that COX-2 was up-regulated in the MCA of MMD patients, especially in hemorrhagic MMD patients. We are led to speculate that COX-2 may be involved in the pathogenesis of MMD and even contribute to the hemorrhagic stroke of MMD patients.

The histopathological features of the middle cerebral artery (MCA) and superficial temporal artery (STA) from moyamoya disease (MMD) and their relationships with gender, age, angiography stage were explored. The causes and the clinical significance of vasculopathy of STA were also discussed. The clinical data and specimens of MCA and STA from 30 MMD patients were collected. Twelve samples of MCA and STA from non-MMD patients served as control group. Histopathological examination was then performed by measuring the thickness of intima and media, and statistical analysis was conducted. The MCA and STA specimens from MMD group had apparently thicker intima and thinner media than those from the control group. There was no significant pathological difference between the hemorrhage group and non-hemorrhage group, and between the males and females in MMD patients. Neither the age nor the digital subtraction angiography (DSA) stage was correlated with the thickness of intima in MCA and STA. MMD is a systemic vascular disease involving both intracranial and extracranial vessels. Preoperative external carotid arteriography, especially super-selective arteriography of the STA, benefits the selection of donor vessel.
