Invigorating blood and dissolving stasis method is a kind of unique therapy of Traditional Chinese Medicine(TCM) treatment, which efficacy has become increasingly prominent in the treatment of ophthalmology.With the further studies of blood stasis and invigorating blood and dissolving stasis therapy, it is widely used in clinical ophthalmology, and get good effects beyond thought, especially when western medicine has no curative effects.It improved the cure rate of fundus oculi disease from the eyelids, conjunctiva, lacrimal sac, vitreous body to the choroid and retina, optic nerve and macula lutea, from surface to fundus, or pathological changes related to inflammation, degeneration, necrosis, atrophy, hyperplasia of fibrous tissue hyperplasia.This paper is aim to explain the definition of invigorating blood and dissolving stasis and make a review of basic research and clinical application about it in several diseases.

OBJECTIVETo investigate the possibility of applying multiplex ligation-dependent probe amplification (MLPA) to the detection of azoospermia factor (AZF) microdeletion on the Y chromosome in infertile men with azoospermia or severe oligozoospermia.

METHODSDNA samples were obtained from 147 azoospermia or severe oligozoospermia patients and 154 normal controls. After denatured at 95 degrees C, the samples were hybridized to the specific probes designed for the AZF region. With the ligase, the hybrid products were amplified by a pair of universal primers labeled with FAM fluorescence, and then separated by capillary electrophoresis for data analysis. Meanwhile all the samples were subjected to multiplex-PCR (mPCR) analysis for sequence-tagged sites (STS) in the AZF region.

RESULTSSTS deletion was detected in 22 (15.0%) of the 147 patients but not in the normal controls. By MLPA, 40 (27.2%) of the patients were found with specific probe omission in the AZF region, as compared with 20 cases in the control group.

CONCLUSIONCompared with mPCR, MLPA has a better sensitivity in detecting AZF microdeletions, and it provides more precise genetic information on the AZF regions, which may contribute to in-depth exploration into the etiological mechanism of impaired spermatogenesis.

OBJECTIVEStriatum may be involved in depressive disorders according to the neuroimaging analysis and clinical data. However, no animal model at present supported the possible role of striatum in the pathogenesis of depression. In the present study, we have investigated the depressive-like behavior in mice recently intoxicated with 3-nitropropionic acid (3-NP), a widely known toxin that selectively damages the striatum in the brain.

METHODSMouse model was made with subacute systemic 3-NP treatment, and the depressive-like behavior was measured using the duration of immobility during forced swimming test (FST).

RESULTSWhen the mice at day 15 post-intoxication just totally recovered from motor deficits, the duration of immobility in FST was significantly longer than that in controls. The depressive-like behavior was not due to the fatigue or general sickness following 3-NP intoxication and could be reversed by the antidepressant, desipramine hydrochloride. In two successive FST in 24 h interval, the depressive-like behavior could be observed again in subsequent FST (at day 16 post-intoxication), and the mice presented a normal "learned helplessness".

CONCLUSIONA novel depression animal model could be established in mice during the initial period of recovery from 3-NP intoxication. The depression-like behavior might occur independently without involvement of cognitive defects, and the striatal lesions may underlie the depression-like behavior attributable to 3-NP intoxication.

OBJECTIVETo study on effects of injection of Huangqi Injectio into Zusanli (ST 36) on the hospital infection and immune function in the patient of schizophrenia.

METHODSThirty inpatients of chronic schizophrenia were treated with injection of Huangqi Injectio into bilateral Zusanli (ST 36), 2 mL each point, thrice each week, for 8 weeks. Relative immune indexes and the hospital infection were investigated.

RESULTSThe hospital infection and the sub-infection were 4 cases (13.3%), 7 cases-times (23.3%) in the injection group; and 9 cases (15.0%), 19 cases-times (31.7%) in the control group, respectively, with no significant difference between the two groups (P>0.05). The drug-administration duration was 7.77 days/case and 11.87 days/case in the two groups, respectively (P<0.01). In the injection group, as compared with that of last 3 years the duration was 7.77 days/case and 14.08 days/case (P<0.01). IgG, IgA, IgM and T-cell subgroups did not have significant changes, but there was the most different value before and after injection in SIL-2R of the no-infection group, and the longer the drug administration duration, the smaller the different values.

CONCLUSIONInjection of Huangqi Injectio into Zusanli (ST 36) has definite effect for prevention of the hospital infection in inpatients of chronic schizophrenia, and SIL-2R is a valuable index for investigation of the hospital of infection.

Objective: To clarify the molecular basis of patients with Bartter syndrome type I and explore the therapeutic effect of trafficking-defective variations by chemical chaperone 4-Phenylbutyric acid(4-PBA). Methods: The clinical characteristics, laboratory findings and genetic data of 3 patients diagnosed with Bartter syndrome type I who were admitted to Department of Nephrology, Children's Hospital of Nanjing Medical University from 2017 to 2018 were retrospectively analyzed. Wild type and variant SLC12A1 gene constructs were transiently overexpressed in HEK293 cells. Western blotting was used to detect the expression levels of Na⁺-K⁺-2Cl^-cotransporter(NKCC2) protein. Immunofluorescent staining was applied to investigate the subcellular localization of NKCC2 protein. In addition, the effect of the chemical chaperone 4-PBA on the expression and localization of the SLC12A1 gene variants was investigated. Unpaired t test was used for statistical analysis of 4-PBA treatment. Results: All the 3 patients (2 males and 1 female), aged 3.0, 4.0 and 1.2 years, respectively. All patients had antenatal onset with polyhydramnios and were born prematurely. After birth, all patients presented with hypochlorine alkalosis accompanied by hypokalemia and hyponatremia. Sequencing analysis revealed that the 3 patients were homozygotes or compound heterozygotes for variants in the SLC12A1 gene. In HEK293 cells, the surface expression of NKCC2 in 3 variants (p.L463S, p.L479V, p.507-510del) are all lower than in wild type (0.718±0.039, 0.287±0.081, 0.025±0.156 vs. 1.001±0.028, t=5.92, 8.35, 30.49, all P<0.01). Moreover, the total protein expression of p.L479V and p.507-510del group were all lower than that in wild type group (0.630±0.032, 0.043±0.003 vs. 1.000±0.111, t=3.21, 8.65, all P<0.05). 4-PBA treatment increased the mature protein expression level of the p.L463S and p. L479V group in 4-PBA treatment group are all higher than the untreated group (0.459±0.018 vs. 1.123±0.024, 0.053±0.012 vs. 1.256±0.037, t=2.75, 18.35, all P<0.05). Cytoplasmic retention of the L479V and 507-510del variants were observed by immunofluorescent staining. 4-PBA treatment could rescue a number of NKCC2 L479V variants to the membrane. Conclusions: The 3 SLC12A1 variants cause expression or subcellular localization defects of the protein. The findings that plasma membrane expression and activity can be rescued by 4PBA might help to develop novel therapeutic strategy for Bartter syndrome type Ⅰ.
