RESUMEN
In the western United States, curly top disease (CTD) is caused by beet curly top virus (BCTV). In California, CTD causes economic loss to processing tomato production in central and southern areas but, historically, not in the north. Here, we document unusual CTD outbreaks in processing tomato fields in the northern production area in 2021 and 2022, and show that these were caused by the rare spinach curly top strain (BCTV-SpCT). These outbreaks were associated with proximity of fields to foothills and unusually hot, dry, and windy spring weather conditions, possibly by altering migrations of the beet leafhopper (BLH) vector from locations with BCTV-SpCT reservoirs. Support for this hypothesis came from the failure to observe CTD outbreaks and BLH migrations in 2023, when spring weather conditions were cool and wet. Our results show the climate-induced emergence of a rare plant virus strain to cause an economically important disease in a new crop and location.

OBJECTIVE: To observe the clinical therapeutic effect of herb-separated moxibustion on dysmenorrhea in ovarian endometriosis. METHODS: A total of 54 patients with ovarian endometriosis dysmenorrhea were randomized into a herb-separated moxibustion group and a waiting-list group, 27 cases in each one (3 cases dropped off in the herb-separated moxibustion group, 4 cases dropped off in the waiting-list group). Herb-separated moxibustion was applied at hypogastrium and lumbosacral area for 30 min in the herb-separated moxibustion group, once a week for 3 months, and oral ibuprofen sustained-release capsule was given to relieve pain when necessary. Excepting giving ibuprofen sustained-release capsule when necessary, no more intervention was adopted in the waiting-list group. Before and after treatment and in 3 months follow-up, visual analogue scale (VAS) score, days of dysmenorrhea, total dose of oral painkiller were observed. RESULTS: Compared before treatment, the VAS scores after tratment and in follow-up were decreased in the herb-separated moxibustion group (P<0.05), and were less than those in the waiting-list group (P<0.05); the days of dysmenorrhea and the total doses of oral painkiller after tratment and in follow-up were decreased in the herb-separated moxibustion group (P<0.05), and were less than those in the waiting-list group (P<0.05). CONCLUSION: Herb-separated moxibustion can effectively improve dysmenorrhea symptom and shorten dysmenorrhea days in patients with ovarian endometriosis.

OBJECTIVE: To compare the therapeutic effects on the relevant symtoms in the patients with dry eye syndrome treated with the acupoint thread-embedding therapy versus topical artificial tears eye drops. METHODS: A total of 88 patients with dry eye syndrome of deficiency lacrima production were randomized into an acupoint thread-embedding therapy group (thread-embedding group) and a control group with topical artificial tears eye drops (medication group), 44 cases in each one. In the thread-embedding group, 3 cases were dropped out. In the thread-embedding group, Ganshu (BL 18), Pishu (BL 20) and Shenshu (BL 23) etc. were selected and the acupoint thread-embedding therapy was operated once every 30 days, totally for two treatments. In the medication group, the topical artificial tears eye drops was used, 4 to 6 times a day, one drop each time, for 8 weeks totally. Separately, before treatment, after 4-week treatment and 8-week treatment as well as in 8 weeks and 12 weeks of the follow-up, the levels of lactoferrin in tears were determined and the scores of the relevant symptoms of ocular surface such as eye dryness, foreign body sensation in the eyes and eye fatigue were evaluated. RESULTS: In the thread-embedding group, after 4-week and 8-week of treatment as well as in 8-week and 12-week follow-up, the scores of eye dryness, foreign body sensation, burning sensation of eye, phengophobia and eye fatigue were reduced significantly as compared with those before treatment (all P<0.05). In the medication group, the relevant symptoms of ocular surface were reduced after 4-week and 8-week treatment as compared with those before treatment (all P<0.05). In the follow-up, the scores of the relevant symptoms of ocular surface in the thread-embedding group were significantly lower than the medication group (all P<0.05). Separately, after 4-week treatment and 8-week treatment as well as in 8 weeks and 12 weeks of the follow-up, the levels of lactoferrin in tears in the thread-embedding group were significantly increased as compared with those before treatment (all P<0.05). The change was not obvious as compared with that before treatment in the medication group (P>0.05). The levels of lactoferrin in tears at each time point after treatment in the thread-embedding group were higher than the medication group (P<0.05). CONCLUSION: The acupoint thread-embedding therapy effectively improves in the relevant symptoms of ocular surface, such as eye dryness, foreign body sensation, burning sensation of eye, phengophobia and eye fatigue, and increases the level of lactoferrin in tears in the patients with dry eye syndrome of deficiency aqueous production. In the follow-up, the therapeutic effects of the acupoint thread-embedding therapy are significantly better than artificial tears eye drops.

OBJECTIVE: To verify the clinical efficacy of acupuncture on motor dysfunction in ischemic stroke of subacute stage. METHODS: The multi-central randomized controlled trial was adopted. One hundred and twenty-six cases of ischemic stroke of subacute stage were randomized into an acupuncture group (61 cases) and a conventional treatment group (65 cases). The basic treatment of western internal medicine and rehabilitation training were applied to the patients of the two groups. In the acupuncture group, acupuncture was supplemented at the body points located on the extensor of the upper limbs and the flexor of the lower limbs. In combination, scalp acupuncture was applied to NS5, MS6 and MS6 on the affected side. The treatment was given 5 times a week and totally 8 weeks were required. The follow-up observation lasted for 3 months. The scores in Fugl-Meyer scale and NIHSS scale and Barthel index were compared between the two groups before treatment, in 4 and 8 weeks of treatment and the 3-month follow-up observation after treatment separately. RESULTS: In 4 and 8 weeks of treatment and the follow-up observation, Fugl-Meyer scale score was improved obviously in the patients of the two groups (all P<0. 01). In 8 weeks of treatment and the follow-up observation, Fugl-Meyer scale score in the acupuncture groupwas im proved much apparently as compared with that in the conventional treatment group [68. 0 (43. 0,86. 5) vs 52. 5 (30.3, 77.0), 77.0 (49.5, 89.0) vs 63. 0 (33.0, 84.0), both P<0. 05]. Except that NIHSS scale score was not reduced apparently in 4 weeks of treatment in the conventional treatment group (P>0.05), the results of NIHSS scale at the other time points were all decreased obviously as compared with those before treatment in the patients of the two groups (all P<0. 01). In 8 weeks of treatment and the follow-up observation, the results in the acupuncture group were reduced much apparently as compared with those in the conventional treatment group [5. 0 (3.0,8.0) vs 7. 0 (3.0,13.8), 4. 0 (1.5,7.0) vs 6.0 (2.0,11.7) ,both P<0. 05]. In 8 weeks of treatment and the follow-up observation, Barthel index was improved obviously as compared with that before treatment in the patients of the two groups (all P<0. 05). The improvement in the acupuncture group was much more significant as compared with the conventional treatment group [75. 0 (60. 0,87. 5) vs 65. O (36. 3, 87. 5), P<0. 051. CONCLUSION: Based on the conventional treatment, Acupuncture achieves the satisfactory clinical efficacy on motor dysfunction in ischemic stroke of subacute stage.

Up to now, in the treatment of stroke patients by acupuncture therapy, three main representative achievements involving scalp acupuncture intervention, "Xing Nao Kai Qiao" (restoring consciousness and inducing resuscitation) acupuncture technique and nape acupuncture therapy have been got. Regarding their neurobiological mechanisms, the scalp acupuncture therapy is based on the functional localization of the cerebral cortex, "Xing Nao Kai Qiao" acupuncture therapy is closely related to nerve stem stimulation, and the nape acupuncture therapy is based on the nerve innervation of the regional neck-nape area in obtaining therapeutic effects. In fact, effects of these three acupuncture interventions are all closely associated with the modern neuroanatomy. In the treatment of post-stroke spastic paralysis, cognitive disorder and depression with acupuncture therapy, modern neuroanatomical knowledge should be one of the key theoretical basis and new therapeutic techniques should be explored and developed continuously.

OBJECTIVE: To verify the therapeutic effect of vascular dementia treated with three-line puncture on the Governor Vessel and Bladder Meridian on head. METHODS: Sixty cases were randomly divided into a head-line puncture group and a routine acupuncture group, 30 cases in each group. In head-line puncture group, line puncture was applied on three lines of the Governor Vessel and Bladder Meridian from anterior hairline to occipital tuberosity. In routine acupuncture group, Yintang (GV 29), Fengchi (GB 20), Sishencong (EX-HN 1) penetrating to Baihui (GV 20) and Shenting (GV 24) penetrating to Shangxing (GV 23) were selected. Once a day, 5 times in a week and 8 weeks totally. Score was evaluated with Mini-Mental State Examination scale (MMSE) before and after treatment, and the therapeutic effects in both groups were compared. RESULTS: The total effective rate of cognitive function was 76. 7% (23/30) in head-line puncture group, superior to that of 43.3% (13/30, P < 0.05) in routine acupuncture group. The MMSE scores in both groups were improved after treatment (both P < 0.01), and it in head-line puncture group was superior to that in routine acupuncture group (P < 0.01). CONCLUSION: Three-line acupuncture on the Governor Vessel and Bladder Meridian on head can remarkably improve the cognitive function of vascular dementia, and the therapeutic effect is superior to that of routine acupuncture.

OBJECTIVE: To observe on the transient analgesic effect of abdominal points transcutaneous electrical nerve stimulation (TENS) combined with abdominal acupuncture according to the holographic theory on pain of neck, shoulder, loin and legs. METHODS: One hundred and twenty cases of pain of neck, shoulder, loin and legs were randomly divided into 4 groups: abdominal acupuncture TENS group, acupoints TENS group, electroacupuneture (EA) group, non-abdominal acupuncture TENS group, 30 cases in each group. All the cases were treated by the same stimulation parameters, but different stimulation points. The VAS scores were recorded before and after treatment. RESULTS: The VAS scores were significantly different before and after treatment in abdominal acupuncture TENS group (P < 0.01); the total effective rate of the transient analgesic effec t was 96.7% in the abdominal acupuncture TENS group, 93.3% in the acupoints TENS group, 96.7% in the EA group with no significant difference among the 3 groups, but with a very significant difference between the abdominal acupuncture TENS group and the non-abdominal acupunctureTENS group (10.0%), P < 0.01. CONCLUSION: Abdominal acupuncture TENS has a better transient analgesic effect and can use less stimulation points to increase the analgesic effect.

OBJECTIVE: To observe the effect of acupoint injection by astragalus injection on local SIgA and pathomorphologial changes in rats with chronic pelvic inflammatory disease (CPID). METHOD: 50 female Wistar rats were randomly devided into 6 groups, in which CPID model was made except the normal group and sham operation group. The astragalus injection group and the 0.9% NaCl injection group were treated by acupoint injection in Guanyuan (RN4) and Zusanli (ST36). The group was fed Qianjinpian solution into stomach. The histopathologic changes of rats' uterus of each group were observed and SIgA in vagina flushing was detected. RESULT: The model group showed inflammatory changes, and astragalus injection group and Qianjinpian group showed little histopathologic changes. The levels of SIgA in astragalus injection group were significantly higher than those in other groups, but that in the model group was the lowest. CONCLUSION: The deficiency of local SIgA lead to repeatedly attack of CPID. The treatment of acupoint injection by astragalus injection can improve the excretion of SIgA, reinforce the local immunity, and prevent the repeatedly attack.

OBJECTIVE: To observe the effect of acupoint injection with astragalus parenteral solution in rat chronic pelvic inflammatory disease (CPID). METHODS: Fifty female Wistar rats were randomly divided into 6 groups: CPID model was induced in 4 groups, in addition to control group and false surgery group. The rats were given acupoint (Guanyuan and Zusanli) injection with astragalus parenteral solution and saline. The drug group was fed with Qianjinpian solutions. The histopathologic changes of uterus were observed and serum IL-2 and TNF-alpha levels detected. RESULT: The rats in the model group showed chronic inflammatory changes, the animals in astragalus parenteral injection group and Qianjinpian group showed little histopathological changes. The serum TNF-alpha levels in the model group were significantly higher than those in the normal group and the astragalus parenteral injection group; while the IL-2 levels in model group were significantly lower than those of other 5 groups. The TNF-alpha and IL-2 levels in astragalus parenteral injection group were similar to those of normal group. CONCLUSION: The treatment of chronic pelvic inflammatory disease with acupoint injection of astragalus parenteral solution might be effective.
